Objective: Indigenous infants are disproportionately more likely to have negative outcomes compared to non-Indigenous infants with suboptimal nutrition in the first 1000 d playing a major role. This review aimed to systematically assess the effectiveness of interventions designed to optimise dietary intake and/or nutrition-related behaviours among Indigenous infants globally and to identify whether Indigenous populations were involved in the co-design of the intervention. Design: Articles published before June 2020 that reported nutrition-related interventions and outcomes for Indigenous infants were identified from a database search. Data extracted included study aims and design, target population, geographical location, the health condition of the participants, intervention characteristics and outcomes. A narrative synthesis consisting of effects and acceptability of the interventions and involvement of participants in the study design were highlighted. Settings: Population-based intervention studies that focused on improving dietary intakes and/or nutrition-related behaviours of Indigenous infants in the first 1000 d of life were included in this review. Results: Of the 2784 studies identified, three studies met the inclusion criteria. These were conducted among two Indigenous tribes in Guatemala and the USA. Two studies reported the food and nutrient intake of participants with one study showing an improvement in dietary intake of the infants. Only one study reported community participation in the study design, intervention design and implementation, and acceptability of the intervention by the participants. Conclusion: Engaging Indigenous communities throughout the entire process of nutrition interventions could have beneficial effects through improved outcomes in the first 1000 d of life.

Asthma is the most common respiratory illness in Aboriginal and Torres Strait Islander Australians. From the Mater Mothers routinely collected perinatal data in Brisbane we have identified that 24% of Indigenous and 17% of non-Indigenous women have pregnancies complicated by asthma. Indigenous women with asthma are more likely to have poorer birth outcomes when compared to non-Indigenous women with asthma, with neonatal death being doubled in asthmatic Indigenous women. These data indicate that asthma management during pregnancy is an unmet need for Indigenous women and essential if we are to avoid these devastating outcomes for Indigenous families.

Objectives To describe the current contraception usage patterns from a cohort of Australian Indigenous women, including their ideal family size and spacing between children. Design Cross‐sectional analysis of data (2012‐2019). Setting Data are from a longitudinal study, the Gomeroi gaaynggal (babies from Gomeroi lands) program, based in rural and remote Gomeroi lands in New South Wales. Participants Women carrying an Indigenous baby who enrolled during pregnancy were eligible for the study. The mother and child are then followed for up to 10 years. Main outcome measures Contraception usage in the postnatal period was recorded, as well as whether they were sexually active, whether they wanted more children and their preferred spacing between children. Medical, social and demographic information was also collected. These measures were self‐reported via an online tool (Survey Monkey®) at their first visit to the study following the birth of their child. Results Ninety‐nine women were included in the analysis. Most women reported that they were sexually active at the time they were questioned about their contraceptive usage. The most popular contraception choices were condoms, the oral contraceptive pill and implant rods. Those answering that they did not want more children had a median of three children already. Those who wanted more children had a median of one child. The majority of the women stated that 2‐3 years between babies was ideal. Conclusion The sampled women had clear beliefs about their ideal family size, in which contraceptive usage played an important part.

INTRODUCTION An optimal diet is imperative in preparing women for pregnancy and this may be influenced by socio-economic status (SES). This research aims to investigate the role of SES on the dietary energy density (ED) in Australian women of preconception age. METHODS A secondary analysis of the Australian National Nutrition and Physical Activity Survey 2011-12 for females aged 18-39 years (n = 1617) was conducted. Dietary intake was assessed by 24-hr recalls and dietary ED by dietary energy per weight (kJ.g-1 ). ED was further categorised as ED of foods and beverages separately. SES was assessed by three variables: Socio-Economic Indexes for Areas (SEIFA), developed by the Australian Bureau of Statistics; income decile; and level of education. Linear mixed model regressions were used to identify associations between ED and SES. RESULTS The median ED for food, beverages and combined food and beverages was 9.38 kJ g-1 , 1.02 kJ g-1 and 7.11 kJ g-1 , respectively. No significant variation was explained by SES variables when analysing combined ED in the adjusted model or ED from foods. Income decile reduced ED of beverages, although with little effect (coefficient: -0.04, P = 0.002). Significant confounders included inactivity, which increased ED in both combined ED and ED foods (coefficient: 0.51, P = 0.001 and coefficient: 0.78, P

Objective: to determine the adequacy of gestational weight gain for a cohort of Indigenous Australian women and investigate whether it is associated with pre-pregnancy body mass index.Design: analysis of observational data collected from a longitudinal cohort study that follows Indigenous Australian women through pregnancy.Setting: women recruited through antenatal clinics in regional and remote towns in NSW, Australia to the Gomeroi gaaynggal program.Participants: 110 pregnant women who either identified as being an Indigenous Australian or as carrying an Indigenous child.Measurements and findings: measurements included weight and height, self-reported pre-pregnancy weight and smoking status, parity and health conditions that may contribute to gestational weight gain, such as hypertensive or diabetic disorders. Compared to the 2009 Institute of Medicine recommendations for gestational weight gain and based on pre-pregnancy body mass index, the rate of adequate gestational weight gain in this cohort was low (26%). 33% of women had inadequate weight gain and 41% had exces-sive weight gain. The highest rate of excessive gestational weight gain was found in overweight women (65%), with rates of 39% and 31% found in healthy and obese (all classes) categories, respectively. Parity (coefficient 4.2, p < 0.01) and hypertension (coefficient 4.3, p = 0.049) were found to be significantly associated with gestational weight gain in mixed model linear regression.Conclusions: few women gained adequate gestational weight gain in this study. Culturally acceptable ways of addressing this issue are needed for this group of women, as inadequate and excessive rates of gestational weight gain have health implications for women and their offspring. Implications for practice: a systematic approach to addressing gestational weight gain within antenatal care is required, including asking about diet and exercise, for all women identifying as Indigenous Aus-tralian.

IntroductionThe perinatal–postnatal family environment is associated with childhood outcomes including impacts on physical and mental health and educational attainment. Family longitudinal cohort studies collect in-depth data that can capture the influence of an era on family lifestyle, mental health, chronic disease, education and financial stability to enable identification of gaps in society and provide the evidence for changes in government in policy and practice.Methods and analysisThe Queensland Family Cohort (QFC) is a prospective, observational, longitudinal study that will recruit 12 500 pregnant families across the state of Queensland (QLD), Australia and intends to follow-up families and children for three decades. To identify the immediate and future health requirements of the QLD population; pregnant participants and their partners will be enrolled by 24 weeks of gestation and followed up at 24, 28 and 36 weeks of gestation, during delivery, on-ward, 6 weeks postpartum and then every 12 months where questionnaires, biological samples and physical measures will be collected from parents and children. To examine the impact of environmental exposures on families, data related to environmental pollution, household pollution and employment exposures will be linked to pregnancy and health outcomes. Where feasible, data linkage of state and federal government databases will be used to follow the participants long term. Biological samples will be stored long term for future discoveries of biomarkers of health and disease.Ethics and disseminationEthical approval has been obtained from the Mater Research Ethics (HREC/16/MHS/113). Findings will be reported to (1) QFC participating families; (2) funding bodies, institutes and hospitals supporting the QFC; (3) federal, state and local governments to inform policy; (4) presented at local, national and international conferences and (5) disseminated by peer-review publications.

Aim The nutritional quality of foods consumed by infants and young children to complement breastfeeding or formula feeding influences growth and development. The aim of this study was to identify the dietary intake of Indigenous infants and young children in the Gomeroi gaaynggal cohort, and evaluate the nutritional adequacy of their intake compared with Australian recommendations. Methods Dietary intake was assessed using diet recalls at approximately 9‐, 12‐ and 24‐month visits. Nutrient values of foods were obtained from AUSNUT 2011‐13 and nutrient intake compared to the Australian Nutrient Reference Values. Foods were categorised into food groups and intakes compared to the Australian Guide to Healthy Eating. Results A total of 206 infants and young children were included in the study. Of these, 95 individual children had dietary data collected between 7.6 and 24.7 months. Infant formula and breastfeeding rates were highest among infants (70% and 20%, respectively). Cow's milk intake was highest among young children (75%). Infants and young children in the cohort met most macro‐ and micronutrient intake recommendations. Few young children met recommendation for iron (42%), no infant met recommendation for omega‐3 fatty acids and almost all exceeded recommendation for sodium. Most young children met daily dairy and fruit recommendations although intake of discretionary foods was high. Conclusions This study found that diets of Indigenous infants and young children met most key nutrient reference targets. Potential target areas that require dietary optimisation have been identified and will be the focus of community‐led strategies in adequate infant nutrition promotion.

Suboptimal nutrition during pregnancy is recognised as a significant modifiable determinant in the development of chronic disease in offspring in later life. The current study aimed: (i) to assess the dietary intakes of pregnant Indigenous Australian women against national recommendations and (ii) to investigate the associations between maternal nutrition during pregnancy and the growth of the offspring, including kidney development in late gestation in the Gomeroi gaaynggal cohort (n = 103). Maternal dietary intake in the third trimester was assessed using the Australian Eating Survey Food Frequency Questionnaire. Estimated fetal weight (EFW) and kidney size were obtained by ultrasound. Birth weight was retrieved from hospital birth records. Of the five key nutrients for optimal reproductive health (folate, iron, calcium, zinc and fibre), the nutrients with the highest percentage of pregnant women achieving the nutrient reference values (NRVs) were zinc (75.7%) and folate (57.3%), whereas iron was the lowest. Only four people achieved all NRVs (folate, iron, calcium, zinc and fibre) important in pregnancy. Sodium and saturated fat intake exceeded recommended levels and diet quality was low, with a median score of 28 out of 73 points. After adjusting for smoking and pre-pregnancy body mass index, only maternal intake of retinol equivalents and the proportion of energy from nutrient-dense or energy-dense, nutrient-poor (EDNP) foods were associated with fetal growth. EFW decreased by 0.13 g and birth weight decreased by 0.24 g for every µg increase in maternal dietary retinol intake. Interestingly, EFW, but not actual birth weight, was positively associated with percentage energy from nutrient dense foods and negatively associated with percentage energy from EDNP foods. Dietary supplement usage was associated with increased birthweight, most significantly iron and folate supplementation. Current dietary intakes of pregnant Australian women from this cohort do not align with national guidelines. Furthermore, current findings show that maternal retinol intake and diet composition during pregnancy can influence fetal growth, but not fetal kidney growth in late gestation. Strategies that aim to support and optimise nutrient intakes of Indigenous pregnant women are urgently needed. Future studies with long-term follow-up of the children in the current cohort to assess renal damage and blood pressure are imperative.

Background The Australian population has an unmet need for contraception. However, evidence suggests contraceptive patterns of Aboriginal and Torres Strait Islander populations are unique. To tailor contraceptive services and meet the contraceptive needs of Aboriginal and Torres Strait Islander people, it is important to understand the contributing factors to contraceptive use and non-use. Methods This study aimed to systematically review and narratively synthesise the evidence exploring the factors influencing contraceptive use among Aboriginal and Torres Strait Islander people. A systematic literature search was initially run in September 2016 and was updated again in April and August of 2018. A qualitative narrative synthesis was conducted from 2018 to 2019. Factors influencing contraceptive use or non-use were explored using a Social Ecological Model. Results The review identified 17 studies meeting the inclusion criteria published between 1972 and 2018. Most of the included studies were qualitative (n = 11), with the remaining studies being mixed methods (n = 3) or quantitative (n = 3). The majority focused on either a localised geographic area or specific Aboriginal or Torres Strait Islander community (n = 11). One study specifically focused on factors influencing contraceptive use, albeit among postpartum women. The remaining studies discussed factors influencing contraceptive use within the context of risky behaviour, sexual transmitted infections, or contraceptive practices more generally. Factors unique to individual communities included community attitudes (e.g. importance of not being too young to have a baby), specific cultural norms (e.g. subincising the penis as part of transition to manhood), and access to culturally appropriate health services. Other factors, including contraceptive characteristics (e.g. discomfort of condoms) and reproductive coercion (e.g. partner wants a baby), were similar to those found in the broader population of Australia and internationally. Most studies were lacking in quality, warranting more methodologically sound studies in the future to further assess the factors contributing to contraceptive use or non-use among Aboriginal and Torres Strait Islander people. Conclusions Identifying community specific facilitators, as well as understanding the more broadly applicable factors contributing to contraceptive use or non-use, is essential if wanting to offer appropriate contraceptive services within an Aboriginal or Torres Strait Islander community.

Introduction An imbalance in angiotensin (Ang) peptides could contribute to the pathophysiology of preeclampsia (PE) and poor fetal growth. Methods We measured maternal plasma levels of Ang peptides and converting enzymes in non-pregnant women (n = 10), in normal pregnant women (n = 59), women delivering small for gestational age babies (SGA, n = 25) across gestation (13-36 weeks) and in women with PE (n = 14) in their third trimester. Results Plasma ACE, ACE2, and Ang-(1-7) levels, and ACE2 activity were significantly higher in normal pregnant women compared with non-pregnant women; neprilysin (NEP) levels were not changed. In SGA pregnancies, ACE and ACE2 levels were higher in early-mid pregnancy compared with normal pregnant women. In women with PE, plasma ACE, ACE2, NEP, and Ang-(1-7) levels and ACE2 activity were lower than levels in normal pregnant women. Conclusion The higher plasma ACE2 levels and activity in pregnancy could be driving the higher Ang-(1-7) levels. The early gestation increases in ACE and ACE2 levels in SGA pregnancies highlights the possibility that these enzymes could be used as potential early biomarkers of poor fetal growth. In women with PE, the reduced ACE2 and NEP levels at term, could be contributing to the reduction in Ang-(1-7) levels. These findings suggest that dysfunctional relationships between two key enzymes in the circulating RAS are involved in the pathogenesis of PE and SGA. Since soluble ACE2 can prevent binding of the novel coronavirus, SARS-CoV-2, to membrane bound ACE2, the interplay between ACE2 and the coronavirus and its impact in pregnancy requires further investigation.

The intrarenal renin-angiotensin system (iRAS) is implicated in the pathogenesis of hypertension, chronic kidney disease and diabetic nephropathy. Urinary angiotensinogen (uAGT) levels reflect the activity of the iRAS and are altered in women with preeclampsia. Since Indigenous Australians suffer high rates and early onset of renal disease, we hypothesised that Indigenous Australian pregnant women, like non-Indigenous women with pregnancy complications, would have altered uAGT levels. The excretion of RAS proteins was measured in non-Indigenous and Indigenous Australian women with uncomplicated or complicated pregnancies (preeclampsia, diabetes/gestational diabetes, proteinuria/albuminuria, hypertension, small/large for gestational age, preterm birth), and in non-pregnant non-Indigenous women.Non-Indigenous pregnant women with uncomplicated pregnancies, had higher uAGT/creatinine levels than non-Indigenous non-pregnant women (P < 0.01), and levels increased as pregnancy progressed (P < 0.001). In non-Indigenous pregnant women with pregnancy complications, uAGT/creatinine was suppressed in the third trimester (P < 0.01). In Indigenous pregnant women with uncomplicated pregnancies, there was no change in uAGT/creatinine with gestational age and uAGT/creatinine was lower in the 2nd and 3rd trimesters than in nonIndigenous pregnant women with uncomplicated pregnancies (P < 0.03, P < 0.007, respectively). The uAGT/creatinine ratios of Indigenous women with uncomplicated or complicated pregnancies were the same.A decrease in uAGT/creatinine with advancing gestational age was associated with increased urinary albumin/creatinine, as is seen in preeclampsia, but it was not specific for this disorder. The reduced uAGT/creatinine in Indigenous pregnant women may reflect subclinical renal dysfunction which limits the ability of the kidney to maintain sodium balance and could indicate an increased risk of pregnancy complications and/or future renal disease.

Objective To determine sources of key nutrients contributing towards nutritional adequacy during pregnancy (fibre, calcium, iron, zinc and folate) in a cohort of women carrying an Indigenous child. Design Analysis of cross-sectional data from a prospective longitudinal cohort study that followed Indigenous women through pregnancy. Setting Women recruited via antenatal clinics in regional and remote locations in NSW, Australia as part of the Gomeroi gaaynggal project. Participants One hundred and fifty-two pregnant Australian women who identified as Indigenous or carrying an Indigenous child. Measurements and Findings Measurement outcomes included demographic information, smoking status, anthropometrics (weight and height,), self-reported pre-pregnancy weight, health conditions and dietary information (24-hour food recall). Findings indicate the inadequate intake of key pregnancy nutrients in this cohort. Supplements contributed to the nutrient adequacy of the cohort with 53% reporting use. As expected, predominant sources of fibre were from core food groups, whereas calcium was attained from a range of sources including food and beverages, with small amounts from supplementation. Importantly, supplements contributed significant amounts of iron, zinc and folate. Key Conclusions There is limited literature on Indigenous Australian maternal nutrition. This study highlights the key dietary contributors of nutritional adequacy during pregnancy for the cohort and that supplementation may be considered a viable source of nutrients during pregnancy for these women. Few women met national nutrient recommendations. The findings present an opportunity to optimise nutrient intakes of Indigenous pregnant women. Implications for practice Culturally appropriate targeted interventions to optimise dietary intakes of Indigenous Australian pregnant women is required. Collaborative support of health workers, Indigenous Australian communities, dietitians, and researchers to raise awareness of nutrition during pregnancy is imperative to achieving nutrient targets and optimising pregnancy outcomes. Targeted interventions provide positive opportunities to achieve improvements.

Maternal obesity during pregnancy has a detrimental impact on offspring renal development and function. This is pertinent to Indigenous Australians as they are twice as likely as non‐Indigenous Australians to develop chronic kidney disease (CKD). The aim of this study was to examine whether there was an association between maternal adiposity and fetal kidney growth in late gestation (>28 weeks) and kidney function in infants, 28 weeks gestation by bioelectrical impedance analysis. Fetal kidney structure was assessed by ultrasound. Renal function indicators (urinary albumin:creatinine and protein:creatinine) were measured in infants from a spot urine collection from nappies. Multiple linear regression and multi‐level mixed effects linear regression models with clustering were used to account for repeated measures of urine. 147 mother–child pairs were examined. Estimated fetal weight (EFW), but not fetal kidney size, was positively associated with maternal adiposity and pre‐pregnancy BMI. When adjusted for smoking, combined kidney volume relative to EFW was negatively associated with maternal percentage body fat. Infant kidney function was not influenced by maternal adiposity and pre‐pregnancy BMI (n = 84 observations). Current findings show that Indigenous babies born to obese mothers have reduced kidney size relative to EFW. We suggest that these babies are experiencing a degree of glomerular hyperfiltration in utero, and therefore are at risk of developing CKD in later life, especially if their propensity for obesity is maintained. Although no impact on renal function was observed at

Issue addressed Undergraduate dietetic students are required to demonstrate cultural awareness and culturally respectful communication to meet national competencies, but exposure to practical experiences may be limited. The Gomeroi gaaynggal ArtsHealth Centre was established in 2009 after community consultation with the Indigenous community in Tamworth, New South Wales. The Centre provides a safe and welcoming space where women can create art while discussing health issues with visiting health professionals and students. The present study aimed to evaluate the cultural experiences of student and new-graduate dietitians visiting an Aboriginal ArtsHealth centre through a quality assurance project. Methods Six student and new-graduate dietitians were invited to provide feedback on their experiences for this report. A generic inductive approach was used for qualitative data analysis. Results Key qualitative themes of ‘building rapport’ and ‘developing cultural understanding’ were identified. Four of the participants interviewed felt they gained a deeper understanding of the context around health disparity for Indigenous Australians through their experiences. Key ways to build rapport with community members were identified. Conclusions Results suggest that first-hand experiences working in an Aboriginal ArtsHealth centre are effective in building cultural competency skills for student and new-graduate dietitians. These experiences could be better supported through improved preparation for the cultural setting, and ongoing monitoring of participant experiences is recommended. So what? The authors encourage undergraduate dietetic programs and students to seek out opportunities for further development of cultural awareness through increased practical experiences working with Indigenous communities.

Adverse pregnancy outcomes including prematurity and low birth weight (LBW) have been associated with life-long chronic disease risk for the infant. Stress during pregnancy increases the risk of adverse pregnancy outcomes. Many studies have reported the incidence of adverse pregnancy outcomes in Indigenous populations and a smaller number of studies have measured rates of stress and depression in these populations. This study sought to examine the potential association between stress during pregnancy and the rate of adverse pregnancy outcomes in Australian Indigenous women residing in rural and remote communities in New South Wales. This study found a higher rate of post-traumatic stress disorder, depression and anxiety symptoms during pregnancy than the general population. There was also a higher incidence of prematurity and LBW deliveries. Unfortunately, missing post-traumatic stress disorder and depressive symptomatology data impeded the examination of associations of interest. This was largely due to the highly sensitive nature of the issues under investigation, and the need to ensure adequate levels of trust between Indigenous women and research staff before disclosure and recording of sensitive research data. We were unable to demonstrate a significant association between the level of stress and the incidence of adverse pregnancy outcomes at this stage. We recommend this longitudinal study continue until complete data sets are available. Future research in this area should ensure prioritization of building trust in participants and overestimating sample size to ensure no undue pressure is placed upon an already stressed participant.

Evidence from animal models indicates that exposure to an obesogenic or hyperglycemic intrauterine environment adversely impacts offspring kidney development and renal function. However, evidence from human studies has not been evaluated systematically. Therefore, the aim of this systematic review was to synthesize current research in humans that has examined the relationship between gestational obesity and/or diabetes and offspring kidney structure and function. Systematic electronic database searches were conducted of five relevant databases (CINAHL, Cochrane, EMBASE, MEDLINE and Scopus). Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines were followed, and articles screened by two independent reviewers generated nine eligible papers for inclusion. Six studies were assessed as being of ‘neutral’ quality, two of ‘negative’ and one ‘positive’ quality. Observational studies suggest that offspring exposed to a hyperglycemic intrauterine environment are more likely to display markers of renal dysfunction and are at higher risk of end-stage renal disease. There was limited and inconsistent evidence for a link between exposure to an obesogenic intrauterine environment and offspring renal outcomes. Offspring renal outcome measures across studies were diverse, with a large variation in offspring age at follow-up, limiting comparability across studies. The collective current body of evidence suggests that intrauterine exposure to maternal obesity and/or diabetes adversely impacts renal programming in offspring, with an increased risk of kidney disease in adulthood. Further high-quality, longitudinal, prospective cohort studies that measure indicators of offspring renal development and function, including fetal kidney volume and albuminuria, at standardized follow-up time points, are warranted.

Objective To synthesise primary research regarding the facilitators and barriers to smoking cessation amongst Aboriginal and/or Torres Strait Islander women during pregnancy. Design An integrative review. Review methods A systematic search of peer-reviewed literature from five databases published from January 2008 to April 2018. Articles were reviewed using the approach outlined by Whittemore and Knafl, with the identified themes collated and synthesised according to study characteristics and barriers and facilitators of smoking cessation. Findings Of the 310 papers retrieved, nine studies were included within the review (five quantitative and four qualitative). The quality of the studies were ascertained via Joanna Briggs Institute checklists for cross sectional analysis, randomized controlled trials, and qualitative research. The overall quality of the research was deemed acceptable. Two facilitators to smoking cessation within the studied population were identified: ‘support to quit’ and ‘information and advice’, while four barriers to smoking cessation within pregnant Aboriginal and/or Torres Strait Islander women were identified: ‘smoking prevalence’, ‘high daily stress’, ‘ambivalence regarding adverse effects of smoking’, and ‘attitudes, knowledge and training of the healthcare professional’. Conclusions Social and familial influences and daily stress have a strong impact on whether a woman feels she can quit smoking during pregnancy. However, in this study, information and advice regarding potential adverse effects of smoking on the foetus, or lack thereof, from health professionals either facilitated cessation of smoking in pregnancy or was a barrier to quitting. Likewise, a lack of awareness from midwives and doctors on smoking cessation strategies, such as nicotine replacement therapy, was a barrier for women. Implications for practice The findings indicate that education regarding the adverse effects of smoking in pregnancy, as well as strategies on smoking cessation from midwives, doctors, and Aboriginal Health Workers within the antenatal period may have a positive effect on current smoking rates among pregnant Aboriginal and/or Torres Strait Islander women. Involving the partner/support person and family of the woman in this education may have a greater impact on smoking cessation rates through the woman gaining social and familial support in her decision to quit. Thus, healthcare workers require additional professional development to provide information and knowledge within a culturally competent manner. Successful smoking cessation programs for Aboriginal and Torres Strait Islander women during pregnancy could have measurable impacts on mortality rates for Indigenous infants and significantly contribute to ‘Closing the Gap’.

Childhood obesity rates are higher among Indigenous compared with non-Indigenous Australian children. It has been hypothesized that early-life influences beginning with the intrauterine environment predict the development of obesity in the offspring. The aim of this paper was to assess, in 227 mother–child dyads from the Gomeroi gaaynggal cohort, associations between prematurity, Gestation Related-Optimal Weight (GROW) centiles, maternal adiposity (percentage body fat, visceral fat area), maternal non-fasting plasma glucose levels (measured at mean gestational age of 23.1 weeks) and offspring BMI and adiposity (abdominal circumference, subscapular skinfold thickness) in early childhood (mean age 23.4 months). Maternal non-fasting plasma glucose concentrations were positively associated with infant birth weight (P=0.005) and GROW customized birth weight centiles (P=0.008). There was a significant association between maternal percentage body fat (P=0.02) and visceral fat area (P=0.00) with infant body weight in early childhood. Body mass index (BMI) in early childhood was significantly higher in offspring born preterm compared with those born at term (P=0.03). GROW customized birth weight centiles was significantly associated with body weight (P=0.01), BMI (P=0.007) and abdominal circumference (P=0.039) at early childhood. Our findings suggest that being born preterm, large for gestational age or exposed to an obesogenic intrauterine environment and higher maternal non-fasting plasma glucose concentrations are associated with increased obesity risk in early childhood. Future strategies should aim to reduce the prevalence of overweight/obesity in women of child-bearing age and emphasize the importance of optimal glycemia during pregnancy, particularly in Indigenous women.

Background: Little is known about the adequacy of nutrient intakes and the overall diet quality of Indigenous Australian pregnant women. The aim of this cross-sectional study was to assess nutrient sufficiency and diet quality, as measured using the Australian Recommended Food Score (ARFS), in pregnant women from the Gomeroi gaaynggal cohort (n = 58).Methods: Maternal dietary intake during pregnancy was assessed using the Australian Eating Survey Food Frequency Questionnaire, which was self-administered in the third trimester. Diet quality was determined using the ARFS. Food group servings and nutrient intakes were compared to the Australian Guide to Health Eating (AGHE) and Australian Nutrient Reference Values (NRVs). The current analysis examined the adequacy of usual intakes from food sources only, excluding supplements. Results: None of the women met all AGHE daily food group serving recommendations. The highest alignment rates were for dairy (33%), meat/alternatives (31%) and vegetables (29.3%). Almost 93% of participants exceeded the recommended intake of energy-dense, nutrient-poor foods and percentage energy from saturated fat was high (15%). Of the five key nutrients for optimal reproductive health (folate, iron, calcium, zinc and fibre), the nutrients with the highest percentage of pregnant women achieving the NRVs were zinc (77.6%) and folate (68.9%), whereas iron was the lowest. Only one person achieved all NRVs (folate, iron, calcium, zinc and fibre) important in pregnancy. The median ARFS was 28 points (maximum of 73).Conclusions: Although the small cohort limits the generalisability of the findings of the present study, the data obtained indicate that the diets of these Indigenous pregnant women are inadequate. Therefore, strategies aiming to optimise nutrient intakes of Indigenous pregnant women are needed urgently.

to determine the adequacy of gestational weight gain for a cohort of Indigenous Australian women and investigate whether it is associated with pre-pregnancy body mass index.analysis of observational data collected from a longitudinal cohort study that follows Indigenous Australian women through pregnancy.women recruited through antenatal clinics in regional and remote towns in NSW, Australia to the Gomeroi gaaynggal program.110 pregnant women who either identified as being an Indigenous Australian or as carrying an Indigenous child.measurements included weight and height, self-reported pre-pregnancy weight and smoking status, parity and health conditions that may contribute to gestational weight gain, such as hypertensive or diabetic disorders. Compared to the 2009 Institute of Medicine recommendations for gestational weight gain and based on prepregnancy body mass index, the rate of adequate gestational weight gain in this cohort was very low (15%). 32% of women had inadequate weight gain and 54% had excessive weight gain. The highest rate of excessive gestational weight gain was found in overweight women (74%), with rates of 48% and 50% found in healthy and obese (all classes) categories, respectively. Parity (coefficient 4.5, p0.01) and hypertension (coefficient 4.8, p = 0.04) were found to be significantly associated with gestational weight gain in mixed model linear regression.few women gained adequate gestational weight gain in this study. Culturally acceptable ways of addressing this issue are needed for this group of women, as inadequate and excessive rates of gestational weight gain have health implications for women and their offspring.a systematic approach to addressing gestational weight gain within antenatal care is required, including asking about diet and exercise, for all women identifying as Indigenous Australian.

Indigenous Australians experience high rates of cardiovascular disease (CVD). The origins of CVD may commence during pregnancy, yet few serum reference values for CVD biomarkers exist specific to the pregnancy period. The Gomeroi gaaynggal research project is a program that undertakes research and provides some health services to pregnant Indigenous women. Three hundred and ninety-nine non-fasting samples provided by the study participants (206 pregnancies and 175 women) have been used to construct reference intervals for CVD biomarkers during this critical time. A pragmatic design was used, in that women were not excluded for the presence of chronic or acute health states. Percentile bands for non-linear relationships were constructed according to the methods of Wright and Royston (2008), using the xriml package in StataIC 13.1. Serum cholesterol, triglycerides, cystatin-C and alkaline phosphatase increased as gestational age progressed, with little change seen in high-sensitivity C-Reactive Protein and γ glutamyl transferase. Values provided in the reference intervals are consistent with findings from other research projects. These reference intervals will form a basis with which future CVD biomarkers for pregnant Indigenous Australian women can be compared.

Image-based dietary records could lower participant burden associated with traditional prospective methods of dietary assessment. They have been used in children, adolescents and adults, but have not been evaluated in pregnant women. The current study evaluated relative validity of the DietBytes image-based dietary assessment method for assessing energy and nutrient intakes. Pregnant women collected image-based dietary records (via a smartphone application) of all food, drinks and supplements consumed over three non-consecutive days. Intakes from the image-based method were compared to intakes collected from three 24-h recalls, taken on random days; once per week, in the weeks following the image-based record. Data were analyzed using nutrient analysis software. Agreement between methods was ascertained using Pearson correlations and Bland-Altman plots. Twenty-five women (27 recruited, one withdrew, one incomplete), median age 29 years, 15 primiparas, eight Aboriginal Australians, completed image-based records for analysis. Significant correlations between the two methods were observed for energy, macronutrients and fiber (r = 0.58–0.84, all p < 0.05), and for micronutrients both including (r = 0.47–0.94, all p < 0.05) and excluding (r = 0.40–0.85, all p < 0.05) supplements in the analysis. Bland-Altman plots confirmed acceptable agreement with no systematic bias. The DietBytes method demonstrated acceptable relative validity for assessment of nutrient intakes of pregnant women.

Background: Dietitians ideally should provide personally tailored nutrition advice to pregnant women. Provision is hampered by a lack of appropriate tools for nutrition assessment and counselling in practice settings. Smartphone technology, through the use of image-based dietary records, can address limitations of traditional methods of recording dietary intake. Feedback on these records can then be provided by the dietitian via smartphone. Efficacy and validity of these methods requires examination. Objective: The aims of the Australian Diet Bytes and Baby Bumps study, which used image-based dietary records and a purpose-built brief Selected Nutrient and Diet Quality (SNaQ) tool to provide tailored nutrition advice to pregnant women, were to assess relative validity of the SNaQ tool for analyzing dietary intake compared with nutrient analysis software, to describe the nutritional intake adequacy of pregnant participants, and to assess acceptability of dietary feedback via smartphone. Methods: Eligible women used a smartphone app to record everything they consumed over 3 nonconsecutive days. Records consisted of an image of the food or drink item placed next to a fiducial marker, with a voice or text description, or both, providing additional detail. We used the SNaQ tool to analyze participants’ intake of daily food group servings and selected key micronutrients for pregnancy relative to Australian guideline recommendations. A visual reference guide consisting of images of foods and drinks in standard serving sizes assisted the dietitian with quantification. Feedback on participants’ diets was provided via 2 methods: (1) a short video summary sent to participants’ smartphones, and (2) a follow-up telephone consultation with a dietitian. Agreement between dietary intake assessment using the SNaQ tool and nutrient analysis software was evaluated using Spearman rank correlation and Cohen kappa. Results: We enrolled 27 women (median age 28.8 years, 8 Indigenous Australians, 15 primiparas), of whom 25 completed the image-based dietary record. Median intakes of grains, vegetables, fruit, meat, and dairy were below recommendations. Median (interquartile range) intake of energy-dense, nutrient-poor foods was 3.5 (2.4-3.9) servings/day and exceeded recommendations (0-2.5 servings/day). Positive correlations between the SNaQ tool and nutrient analysis software were observed for energy (ρ=.898, P

Background: Pregnancy can be a stressful time for many women. There is ample evidence of numerous physical and mental health inequities for Indigenous Australians. For those Indigenous women who are pregnant, it is established that there is a higher incidence of poor physical perinatal outcomes when compared with non-Indigenous Australians. However, little evidence exists that examines stressful events and post-traumatic stress disorder (PTSD) symptoms in pregnant women who are members of this community.Aims: To quantify the rates of stressful events and PTSD symptoms in pregnant Indigenous women.Methods: One hundred and fifty rural and remote Indigenous women were invited to complete a survey during each trimester of their pregnancy. The survey measures were the stressful life events and the Impact of Events Scale.Results: Extremely high rates of PTSD symptoms were reported by participants. Approximately 40% of this group exhibited PTSD symptoms during their pregnancy with mean score 33.38 (SD = 14.37) significantly higher than a study of European victims of crisis, including terrorism attacks (20.6, SD = 18.5).Conclusions: The extreme levels of PTSD symptoms found in the women participating in this study are likely to result in negative implications for both mother and infant. An urgent response must be mounted at government, health, community development and research levels to address these findings. Immediate attention needs to focus on the development of interventions to address the high levels of PTSD symptoms that pregnant Australian Indigenous women experience.

Indigenous Australians continue to experience disparities in chronic diseases, many of which have nutrition-related trajectories. Optimal nutrition throughout the lifespan is protective for a number of adverse health outcomes, however little is known about current dietary intakes and related anthropometric outcomes of Indigenous women and their infants. Research is required to identify nutrition issues to target for health promotion activities. The Gomeroi gaaynggal programme is an ongoing, prospective cohort of pregnant Indigenous Australian women and their children. A cross-sectional examination of postnatal dietary intakes and anthropometric outcomes of mothers and children are reported. To date, 73 mother–child dyads have participatedpostpartum. Breastfeeding initiation was 85.9% and median (interquartile range) duration of any breastfeeding was 1.4 (0.5–4.0) months. Infants were introduced to solid foods at 5.0 months (4.0–6.0) and cow’s milk at 12.0 (10.0–13.0) months. At 12 monthspostpartum, 66.7% of women were overweight or obese, 63.7% at 2 years. Compared with recommendations, reported median maternal nutrient intakes from 24-h recall were low in fibre, folate, iodine, calcium, potassium and vitamin D and high in proportions of energy from total and saturated fat. Limitations of this study include a small sample size and incomplete data for the cohort at each time point. Preliminary data from this ongoing cohort of Indigenous Australian women and children suggest that women may need support to optimize nutrient intakes and to attain a healthy body weight for themselves and their children.

This article argues that mental health services need to be designed according to the specific needs of Indigenous families, including support for those who are suffering distress related to forced removal.

Indigenous Australians have high rates of chronic diseases, the causes of which are complex and include social and environmental determinants. Early experiences in utero may also predispose to later-life disease development. The Gomeroi gaaynggal study was established to explore intrauterine origins of renal disease, diabetes and growth in order to inform the development of health programmes for Indigenous Australian women and children. Pregnant women are recruited from antenatal clinics in Tamworth, Newcastle and Walgett, New South Wales, Australia, by Indigenous research assistants. Measures are collected at three time points in pregnancy and from women and their children at up to eight time points in the child’s first 5 years. Measures of fetal renal development and function include ultrasound and biochemical biomarkers. Dietary intake, infant feeding and anthropometric measurements are collected. Standardized procedures and validated tools are used where available. Since 2010 the study has recruited over 230 women, and retained 66 postpartum. Recruitment is ongoing, and Gomeroi gaaynggal is currently the largest Indigenous pregnancy-through-early-childhood cohort internationally. Baseline median gestational age was 39.1 weeks (31.5–43.2, n=110), median birth weight was 3180 g (910–5430 g, n=110). Over one third (39.3%) of infants were admitted to special care or neonatal nursery. Nearly half of mothers (47.5%) reported tobacco smoking during pregnancy. Results of the study will contribute to knowledge about origins of chronic disease in Indigenous Australians and nutrition and growth of women and their offspring during pregnancy and postpartum. Study strengths include employment and capacity-building of Indigenous staff and the complementary ArtsHealth programme.

Background Children residing in rural areas face unique barriers to physical activity participation. Further, while children with a disability who reside in metropolitan areas face barriers hindering physical activity, rurally residing children with a disability may face the augmented combination of these barriers that could have negative health implications. Parents are often the key advocates for children with disabilities and are likely to have valuable insight into the opportunities and barriers to physical activity for their child. Objective The aim of this study was to investigate parents' perceptions of physical activity opportunities for their child with a disability in a rural area. Methods A mixed method survey examining parent's perceptions of their child's physical activity and possible barriers to participation was mailed to rurally residing parents of children with a disability. Quantitative data were analyzed descriptively using frequencies and proportions. Qualitative data were analyzed using qualitative content analysis. Results There were 34 completed surveys, a response rate of 37%. Participants' responses indicated 74% of children were not meeting daily recommendations of physical activity. Participation barriers including emotional, physical and environmental issues. Three main themes emerged from qualitative data; segregation, access to facilities and resources and barriers specific to the child. Conclusion The children in this study were from rural areas and face similar barriers to children in metropolitan areas. However, they are also confronted with the same barriers children without a disability in rural areas face, participating in physical activity. This may have detrimental effects on their health and development.

Personalised medicine is a newly emerging field with much to offer to all populations in improved clinical treatment options. Since the 1970s, clinicians and researchers have all been working towards improving the health of Indigenous Australians. However, there has been little research on the impact of genetics on Indigenous health, how genetic and environmental factors interact to contribute to poor health in Indigenous people, and how genetic factors specific to Indigenous people affect their responses to particular treatments. This short review highlights the urgent need for more genetic studies specific to Indigenous people in order to provide more appropriate care and to improve health outcomes. This paper explores why genetic work with Indigenous communities has been limited, how personalised medicine could benefit Indigenous communities, and highlights a number of specific instances in which personalised medicine has been critical for improving morbidity and mortality in other high-risk groups. In order to take the next step in advancing the health of Indigenous peoples, targeted research into the genetic factors behind chronic diseases is critically needed. This research may allow clinicians a better understanding of how genetic factors interact with environmental factors to influence an Indigenous Australian's individual risk of disease, prognosis, and response to therapies. It is hoped that this knowledge will produce clinical interventions that will help deliver clearly targeted, more appropriate care to this at-risk population.

The intrauterine environment is critical for fetal growth and organ development. Evidence from animal models indicates that the developing kidney is vulnerable to suboptimal maternal nutrition and changes in health status. However, evidence from human studies are yet to be synthesised. Therefore, the aim of the current study was to systematically review current research on the relationship between maternal nutrition during pregnancy and offspring kidney structure and function in humans. A search of five databases identified 9501 articles, of which three experimental and seven observational studies met the inclusion criteria. Nutrients reviewed to date included vitamin A (n = 3), folate and vitamin B12 (n = 2), iron (n = 1), vitamin D (n = 1), total energy (n = 2) and protein (n = 1). Seven studies were assessed as being of “positive” and three of “neutral” quality. A variety of populations were studied, with limited studies investigating maternal nutrition during pregnancy, while measurements of offspring kidney outcomes were diverse across studies. There was a lack of consistency in the timing of follow-up for offspring kidney structure and/or function assessments, thus limiting comparability between studies. Deficiencies in maternal folate, vitamin A, and total energy during pregnancy were associated with detrimental impacts on kidney structure and function, measured by kidney volume, proteinuria, eGFRcystC and mean creatinine clearance in the offspring. Additional experimental and longitudinal prospective studies are warranted to confirm this relationship, especially in Indigenous populations where the risk of renal disease is greater.

The life expectancy of Indigenous Australians is amongst the lowest of any population group within developed nations and chronic diseases collectively account for over 80% of the gap in life expectancy between Indigenous and non-Indigenous Australians. The Gomeroi gaaynggal cohort is a prospective, longitudinal maternal-infant cohort established to examine the origins of chronic disease in Indigenous Australians. This study aimed to determine the major antenatal factors associated with adverse birth outcomes (preterm delivery, low birth weight) and other pregnancyrelated complications (gestational diabetes and hypertensive disorders of pregnancy) in Indigenous Australian women. Pregnant women who identified as Indigenous Australians or pregnant non-Indigenous women giving birth to an Indigenous infant were eligible to participate in the cohort (n=227). Physical measurements and biological sample collection (including blood and urine) were undertaken up to 3 times in pregnancy. Median weight and BMI of the cohort was 80.7 kg and 30.3 kg/m2 at enrolment (median 23 weeks gestation). 43% reported smoking cigarettes during pregnancy. Of the 158 women in whom pregnancy outcomes were known, 43% had an uncomplicated pregnancy, 13.9% delivered preterm, 14.6% delivered a small-for-gestational age infant, 10% developed a hypertensive disorder of pregnancy, and 6.3% developed gestational diabetes. In addition, many women showed evidence of underlying renal dysfunction (proteinuria or albuminuria). The ratio of male to female offspring in this cohort was 1.38. Eightyseven percent of preterm infants were male, as were 83.3% of babies from women with gestational hypertension. This skewed sex distribution was far higher than for those who had a healthy pregnancy outcome (59%). This study demonstrates that key factors including maternal obesity, exposure to cigarette smoke and underlying renal impairment, influence pregnancy outcome. Preliminary findings from this study also suggest that more male babies are born early and from complicated pregnancies in this Indigenous cohort.

Introduction Indigenous people continue to experience health disparities relative to non-Indigenous populations. Interventions to improve nutrition during pregnancy in these groups may improve health outcomes for mothers and their infants. The effectiveness of existing nutrition intervention programs has not been reviewed previously. Objective The objective was to identify interventions targeting improving nutrition-related outcomes for pregnant Indigenous women residing in Organisation for Economic Co-operation and Development countries, and to identify positive factors contributing to successful programs. Methods Thirteen electronic databases were searched up until October 2015. Key words identified studies intervening to improve nutrition-related outcomes for pregnant Indigenous women. Two reviewers assessed articles for inclusion and study quality and extracted data. Only studies published in English were included. Data were summarized narratively. Results Abstracts and titles were screened (n=2,566) and 315 full texts were reviewed for eligibility. This review included 27 articles from 20 intervention programs from Australia, Canada, and the United States. The most prevalent measurable outcomes were birth weight (n=9) and breastfeeding initiation/duration (n=11). Programs with statistically significant results for these outcomes employed the following nutrition activities: individual counseling/education (n=8); delivery by senior Indigenous woman (n=2), peer counselor (n=3), or other Indigenous health worker (n=4); community-wide interventions (n=2); media campaigns (n=2); delivery by non-Indigenous health professional (n=3); and home visits (n=3). Conclusions Heterogeneity of included studies made it challenging to make firm recommendations regarding program success. Authors of included studies recommended community consultation be included when designing studies and working with communities at all stages of the research process. Individualized counseling/education can contribute to successful program outcomes, as can the use of Indigenous workers to deliver program content. Limitations of some studies included a lack of details on interventions and the use of nonrandom control groups. Future studies should include detailed descriptions of intervention components and include appropriate evaluation protocols.

This paper recounts a journey of discovery by a scientist who inadvertently takes on coordination of an ArtsHealth programme. The dynamics of role change are explored showcasing the vulnerabilities and fears that often accompany these career adjustments. The associated ArtsHealth programme (Gomeroi gaaynggal) works with Aboriginal and Torres Strait Islander women in Australia throughout their pregnancy to improve understanding of issues that impact the health of themselves and their developing baby. By wearing someone else shoes, the scientist is immersed in the project and must confront issues including skill mix, learning and cultural diversity.

Follistatin has been isolated from human placenta and has been identified in human foetal membranes and fluids. Serum follistatin levels in women rise during pregnancy particularly near term. In this study, we examined the effect of induction and stage of labour on maternal plasma concentrations of follistatin. Women who gave birth after a normal pregnancy were retrospectively divided into three groups: those who went in labour spontaneously (n= 33), needed induction by amniotomy and IV oxytocin (n= 18) or underwent planned caesarean section (n= 10). Serum was collected at 38–40 weeks of gestation, periodically through labour with a vaginal examination and once within 36 h postpartum and assayed for oestradiol, progesterone, prolactin and C-reactive protein. Follistatin was measured using a rabbit antiserum (#204) raised against purified 35 kDa bovine follistatin. Human recombinant follistatin was used as both standard and tracer. Concentrations of follistatin at 38–40 weeks of gestation were significantly different between groups. Those who had a spontaneous labour had concentrations higher than those who were induced. Similarly, those who were induced had concentrations higher than those who underwent a caesarean. In the spontaneous group, follistatin rose during labour, peaking at 57.9 ± 5.48 ng/ml at > 3 cm of cervical dilation, and after delivery follistatin decreased to 26.16 ± 3.4 ng/ml at 24 h post-delivery. In induced patients follistatin continued increasing to peak following delivery at 26.9 ± 3.0 ng/ml and decreased at > 3 h post-delivery. Follistatin concentrations in caesarean section patients at 24 h post-surgery (18.53 ± 3.74 ng/ml) were not different from that before the surgery and were comparable with the other two groups. Follistatin is clearly implicated in the onset of labour; however, further studies with a larger cohort of women are necessary to determine the nature of its role.

To see if urinary angiotensinogen (uAGT)/creatinine and other urinary components of the RAS could be used to detect renal disease in pregnancy, as renal disease predisposes to preeclampsia.Plasma and urinary prorenin, ACE and AGT (iRAS) were measured by ELISA. Urinary active renin levels were measured enzymatically (9 males, 10 non pregnant, 61 Australian Indigenous pregnant women).No relationships between plasma RAS and iRAS were found. In non-pregnant females plasma AGT levels were inversely related to protein and albumin/creatinine (r=-0.72, P=0.019, n=10; r=-0.65, P=0.042, n=10). In pregnancy, plasma ACE levels were related to protein/creatinine (r=0.29, P=0.036, n=54). Urinary protein/creatinine was not related to iRAS activity (males and non-pregnant females) but in pregnancy was related to prorenin and active renin/creatinine (r=0.45, P=0.02, n=26 r=0.47, P0.001, n=50). Urinary albumin/creatinine was related to uAGT and active renin/creatinine in pregnancy (r=0.39, P=0.005, n=51; r=0.37, P=0.008, n=51). uACE/creatinine and uAGT/creatinine were related (r=0.52, P0.001, n=51).Excretion of components of the iRAS is independent of plasma levels. Not only is uAGT/creatinine related to albumin/creatinine but there are similar relationships with other iRAS components. Measurement of the iRAS in human pregnancy may detect early stage renal disease, endemic in Indigenous Australians.

Context: Australian Aboriginal communities in urban, rural and remote areas are continuing to suffer high rates of perinatal mortality and morbidity that will impact on the future health of the community. It has been well documented that Aboriginal women have extreme distrust of mainstream pregnancy-related health care and suggested that late entry into antenatal care is as high as 50% in the Aboriginal population. Although medical and midwifery staff have long discussed strategies to improve uptake of antenatal health care for Aboriginal women, researchers in many areas have found the recruitment of Aboriginal people into scientific studies almost impossible. This article seeks to share the strategies that have been developed over a period of time by the authors that have proved useful for recruitment and retention into research. It is anticipated that these strategies would also apply for health practitioners in maintaining their patients for clinical care management.Issue: Although each research location (regional, rural and remote) has had to spend time determining what approach is best for meeting the research outcomes, many of these suggestions become applicable to clinicians seeking to develop better connections with Aboriginal patients in their clinics. With the management of ongoing chronic health conditions for Aboriginal people a priority in 'Closing the Gap', a number of these suggestions could easily be implemented by clinicians. Remembering that each community has specific needs that must be addressed, priorities for assistance for that community will be easily identifiable after community consultation (eg transport, or ability to access medical testing). Opportunities for the use of new social media (eg Facebook) as communication tools for researchers and clinicians will have increasing applicability as further software updates are created.Lessons learnt: With open and trusting dialogues between researchers, clinicians and Aboriginal communities, we can go a long way towards understanding the needs of individual communities and working in partnerships to close the gap.
