Information on fortifiable food consumption is essential to design, monitor and evaluate fortification programmes, yet detailed methods like 24‐h recalls (24HRs) that provide such data are rarely conducted. Simplified questionnaire‐based methods exist but their validity compared with 24HRs has not been shown. We compared two simplified methods (i.e., a household food acquisition and purchase questionnaire [FAPQ] and a 7‐day semiquantitative food frequency questionnaire [SQ‐FFQ]) against 24HRs for estimating fortifiable food consumption. We assessed the consumption of fortifiable wheat flour and oil using a FAPQ and, for wheat flour only, a 7‐day SQ‐FFQ and compared the results against 24HRs. The participants included children 12−18 months (n = 123) and their mothers 18−49 years selected for a study assessing child vitamin A intake and status in Mandaluyong City, Philippines. For fortifiable wheat flour, the FAPQ estimated considerably lower mean intakes compared to 24HRs for children and mothers (2.2 vs. 14.1 g/day and 5.1 vs. 42.3 g/day, respectively), while the SQ‐FFQ estimated slightly higher mean intakes (15.7 vs. 14.1 g/day and 51.5 vs. 42.3 g/day, respectively). For fortifiable oil, the FAPQ estimated considerably higher mean intakes compared to 24HRs for children and mothers (4.6 vs. 1.8 g/day and 12.5 vs. 6.1 g/day, respectively). The SQ‐FFQ, but not the FAPQ, generated useful information on fortifiable food consumption that can inform fortification programme design and monitoring decisions in the absence of more detailed individual‐level data. Potential adaptations to improve the FAPQ, such as additional questions on foods prepared away from home and usage patterns, merit further research. Key messages: Fortifiable (i.e., industrially processed) food consumption data are essential to design, monitor and evaluate fortification programmes, yet 24‐h recalls (24HRs) that provide such data are rarely conducted.Simplified methods, such as targeted food acquisition and purchase questionnaires (FAPQs) and semiquantitative food frequency questionnaires (SQ‐FFQs), exist but their validity compared to 24HRs has not been shown.Among Filipino children 12−18 months and their mothers, the SQ‐FFQ generated useful information on fortifiable wheat flour consumption while the FAPQ systematically underestimated wheat flour and overestimated oil.Further research could strengthen the FAPQ to better capture foods prepared away from home and usage patterns.

Using a quasi‐experimental design, our study aimed to determine the effectiveness of the 'Eggs Make Kids Sharp & Bright and Strong & Active' demand‐creation campaign in Nigeria. The intervention arm received emotionally compelling radio and television advertisements about eggs, and was exposed to promotional activities and advertising about eggs at points of purchase, schools and health facilities; the comparison arm received no intervention. Children 6–59 months of age (intervention: n = 1359; comparison: n = 1485) were assessed 14 months apart. Intent‐to‐treat analyses with analysis of covariance method assessed the impact of the intervention on caregivers' behaviour towards eggs, caregivers' willingness to pay for eggs, availability of eggs in households, and consumption of eggs by children 6–59 months of age. Analyses were adjusted for possible confounders and perceived effects of COVID‐19 on finances and food consumption. Compared to the comparison arm, the intervention arm showed a greater prevalence of household egg acquisition (odds ratio = 1.34, p < 0.0001), and larger improvements in caregiver self‐efficacy (β = 0.242, p = 0.004) and intent to feed eggs to children (β = 0.080, p = 0.021). No effects were found on children's egg consumption or caregivers' reported willingness to pay for eggs. The lack of impact on child egg consumption despite increased acquisition of eggs and caregiver self‐efficacy suggests that other barriers to child consumption may exist. Additional research should further investigate factors that may influence intrahousehold distribution of eggs and whether these may also influence other nutritious foods. Key messages: An emotionally engaged demand creation campaign around eggs resulted in small improvements in household acquisition of eggs and caregivers' self‐efficacy and intent to feed eggs to their child 6–59 months of age, but did not improve egg consumption in children.Economic hardships imposed by the COVID‐19 pandemic and low interpersonal communication associated with the campaign may have contributed to the lack of effects of egg consumption.Demand generation activities as stand‐alone activities are insufficient in improving egg consumption among children 6–59 months of age in this context.

Calcium intake remains inadequate in many low‐ and middle‐income countries, especially in Africa and South Asia, where average intakes can be below 400 mg/day. Given the vital role of calcium in bone health, metabolism, and cell signaling, countries with low calcium intake may want to consider food‐based approaches to improve calcium consumption and bioavailability within their population. This is especially true for those with low calcium intake who would benefit the most, including pregnant women (by reducing the risk of preeclampsia) and children (by reducing calcium‐deficiency rickets). Specifically, some animal‐source foods that are naturally high in bioavailable calcium and plant foods that can contribute to calcium intake could be promoted either through policies or educational materials. Some food processing techniques can improve the calcium content in food or increase calcium bioavailability. Staple‐food fortification with calcium can also be a cost‐effective method to increase intake with minimal behavior change required. Lastly, biofortification is currently being investigated to improve calcium content, either through genetic screening and breeding of high‐calcium varieties or through the application of calcium‐rich fertilizers. These mechanisms can be used alone or in combination based on the local context to improve calcium intake within a population. [ABSTRACT FROM AUTHOR]

Daily consumption of iron‐containing supplements is recommended for all pregnant women but there is no approved global standard indicator for assessing supplementation coverage. Furthermore, the validity of commonly used coverage indicators for iron‐containing supplement consumption is questionable. The WHO–UNICEF Technical Expert Advisory Group on Nutrition Monitoring, and partners, have systematically worked to identify a feasible and valid indicator of iron‐containing supplement coverage for reporting by countries. In 2019, we conducted key informant interviews with respondents in eight countries, fielded an online survey (in three languages using SurveyMonkey) to which 142 nutrition professionals from 52 countries responded, and used Demographic and Health Surveys (DHS) data from four countries to assess determinants of the quality of iron‐containing supplement coverage data. Less than half (45%) of online survey respondents were satisfied with the current methods for collecting iron‐containing supplement coverage data in their context. Recommended changes by study respondents include recall period <5 years, adding questions about counselling, including other beneficiary groups, and assessing supply chain functionality. The DHS analysis suggested an association between time since pregnancy and data quality. Data heaping on multiples of 30 was observed in 40%–75% of data. There is a clear demand for a revised indicator and measurement guidance for coverage of iron‐containing supplementation during pregnancy. Future research should continue the development and validation of a global indicator, to more precisely validate the quality of recall data, including the distinction between distribution and consumption using various question formulations. Key messages: Health and nutrition professionals have described concerns with current methods for reporting coverage of daily iron‐containing supplementation in pregnant women.The long recall period (5 years) of commonly used iron‐containing supplement consumption indicators calls into question the validity of these indicators.Our study indicates that there is demand for a revised indicator and guidance for data collection.

Most low‐ and middle‐income countries present suboptimal intakes of calcium during pregnancy and high rates of mortality due to maternal hypertensive disorders. Calcium supplementation during pregnancy is known to reduce the risk of these disorders and associated complications, including preeclampsia, maternal morbidity, and preterm birth, and is, therefore, a recommended intervention for pregnant women in populations with low dietary calcium intake (e.g., where ≥25% of individuals in the population have intakes less than 800 mg calcium/day). However, this intervention is not widely implemented in part due to cost and logistical issues related to the large dose and burdensome dosing schedule (three to four 500‐mg doses/day). WHO recommends 1.5–2 g/day but limited evidence suggests that less than 1 g/day may be sufficient and ongoing trials with low‐dose calcium supplementation (500 mg/day) may point a path toward simplifying supplementation regimens. Calcium carbonate is likely to be the most cost‐effective choice, and it is not necessary to counsel women to take calcium supplements separately from iron‐containing supplements. In populations at highest risk for preeclampsia, a combination of calcium supplementation and food‐based approaches, such as food fortification with calcium, may be required to improve calcium intakes before pregnancy and in early gestation.

Double fortified salt (DFS) has proven efficacy in addressing iron deficiency and anaemia, thus improving maternal and child nutrition outcomes. However, DFS delivery in large‐scale settings is less understood, with limited documentation of its fidelity of implementation (FOI). We assessed the FOI of the DFS intervention in Uttar Pradesh, India, to improve the design and implementation of such programmes that aim to reduce the anaemia burden, especially in women of reproductive age (WRA). We conducted in‐depth interviews with DFS programme staff (n = 25) and end‐user WRAs (23), guided by a programme impact pathway. We transcribed and thematically analysed the interviews and used an adapted analytic framework to document FOI across four domains—objects of intervention, implementation staff, implementation context and target of implementation. DFS utilisation remained low due to a combination of factors including poor product quality, distribution challenges, ineffective promotion and low awareness amongst end‐user WRAs. Motivation levels were higher amongst district‐level staff compared to frontline staff, who lacked supervisory support and effective incentives to promote DFS. Three typologies of DFS users emerged—'believers', 'thrifters' and 'naysayers'—who indicated differing reasons for DFS purchase and its use or nonuse. The implementation of the DFS programme varied significantly from its theorised programme impact pathway. The adapted analytic framework helped document FOI and assess the programme's readiness for impact assessments and subsequent scale‐up. The programme needs product quality improvements, incentivised distribution and stronger promotion to effectively deliver and improve the realisation of its potential as an anaemia prevention strategy.

Prenatal micronutrient deficiencies are associated with negative maternal and birth outcomes. Multiple micronutrient supplementation (MMS) during pregnancy is a cost‐effective intervention to reduce these adverse outcomes. However, important knowledge gaps remain in the implementation of MMS interventions. The Child Health and Nutrition Research Initiative (CHNRI) methodology was applied to inform the direction of research and investments needed to support the implementation of MMS interventions for pregnant women in low‐ and middle‐income countries (LMIC). Following CHNRI methodology guidelines, a group of international experts in nutrition and maternal health provided and ranked the research questions that most urgently need to be resolved for prenatal MMS interventions to be successfully implemented. Seventy‐three research questions were received, analyzed, and reorganized, resulting in 35 consolidated research questions. These were scored against four criteria, yielding a priority ranking where the top 10 research options focused on strategies to increase antenatal care attendance and MMS adherence, methods needed to identify populations more likely to benefit from MMS interventions and some discovery issues (e.g., potential benefit of extending MMS through lactation). This exercise prioritized 35 discrete research questions that merit serious consideration for the potential of MMS during pregnancy to be optimized in LMIC. [ABSTRACT FROM AUTHOR]

Anemia is an important public health challenge and accurate prevalence estimates are needed for program planning and tracking progress. While venous blood assessed by automated hematology analyzers is considered gold standard, most population‐based surveys use point‐of‐care diagnostics and capillary blood to estimate population prevalence of anemia. Several factors influence hemoglobin (Hb) concentration, including human and analytic error, analysis method, and type of instrument, but it is unclear whether biological variability exists between venous and capillary blood. The objective of this paper was to systematically review sources of Hb variability and the potential biological basis for venous and capillary differences. We use data from a recent survey in the state of Uttar Pradesh, India, to illustrate the implications on anemia prevalence estimates. Significant differences in Hb concentration between capillary and venous blood samples are common. Most but not all find capillary Hb concentration to be higher than venous. Instrument/method variability and human error play an important role, but cannot fully explain these differences. A normative guide to data collection, analysis, and anemia diagnosis is needed to ensure consistent and appropriate interpretation. Further research is needed to fully understand the biological implications of venous and capillary Hb variability. [ABSTRACT FROM AUTHOR]

Vitamin D is an essential nutrient for bone health and may influence the risks of respiratory illness, adverse pregnancy outcomes, and chronic diseases of adulthood. Because many countries have a relatively low supply of foods rich in vitamin D and inadequate exposure to natural ultraviolet B (UVB) radiation from sunlight, an important proportion of the global population is at risk of vitamin D deficiency. There is general agreement that the minimum serum/plasma 25‐hydroxyvitamin D concentration (25(OH)D) that protects against vitamin D deficiency–related bone disease is approximately 30 nmol/L; therefore, this threshold is suitable to define vitamin D deficiency in population surveys. However, efforts to assess the vitamin D status of populations in low‐ and middle‐income countries have been hampered by limited availability of population‐representative 25(OH)D data, particularly among population subgroups most vulnerable to the skeletal and potential extraskeletal consequences of low vitamin D status, namely exclusively breastfed infants, children, adolescents, pregnant and lactating women, and the elderly. In the absence of 25(OH)D data, identification of communities that would benefit from public health interventions to improve vitamin D status may require proxy indicators of the population risk of vitamin D deficiency, such as the prevalence of rickets or metrics of usual UVB exposure. If a high prevalence of vitamin D deficiency is identified (>20% prevalence of 25(OH)D < 30 nmol/L) or the risk for vitamin D deficiency is determined to be high based on proxy indicators (e.g., prevalence of rickets >1%), food fortification and/or targeted vitamin D supplementation policies can be implemented to reduce the burden of vitamin D deficiency–related conditions in vulnerable populations. Here we report the outcome of a working group convened in January and March 2017 by the Sackler Institute for Nutrition Science at the New York Academy of Sciences and the Bill & Melinda Gates Foundation to assess the global prevalence and disease burden of vitamin D deficiency, and population‐based strategies to improve vitamin D status, particularly in low‐ and middle‐income countries. The working group aimed to examine definitions of vitamin D deficiency based on biomarkers and correlations with disease or health outcomes. [ABSTRACT FROM AUTHOR]

Abstract: Child stunting reduction is the first of 6 goals in the Global Nutrition Targets for 2025 and a key indicator in the second Sustainable Development Goal of Zero Hunger. The prevalence of child stunting in Indonesia has remained high over the past decade, and at the national level is approximately 37%. It is unclear whether current approaches to reduce child stunting align with the scientific evidence in Indonesia. We use the World Health Organization conceptual framework on child stunting to review the available literature and identify what has been studied and can be concluded about the determinants of child stunting in Indonesia and where data gaps remain. Consistent evidence suggests nonexclusive breastfeeding for the first 6 months, low household socio‐economic status, premature birth, short birth length, and low maternal height and education are particularly important child stunting determinants in Indonesia. Children from households with both unimproved latrines and untreated drinking water are also at increased risk. Community and societal factors—particularly, poor access to health care and living in rural areas—have been repeatedly associated with child stunting. Published studies are lacking on how education; society and culture; agriculture and food systems; and water, sanitation, and the environment contribute to child stunting. This comprehensive synthesis of the available evidence on child stunting determinants in Indonesia outlines who are the most vulnerable to stunting, which interventions have been most successful, and what new research is needed to fill knowledge gaps.

Iron deficiency anaemia is estimated to be the leading cause of years lived with disability among children. Young children's diets are often inadequate in iron and other micronutrients, and provision of essential vitamin and minerals has long been recommended. With the limited programmatic success of iron drop/syrup interventions, interest in micronutrient powders (MNP) has increased. MNP are a mixture of vitamins and minerals, enclosed in single-dose sachets, which are stirred into a child's portion of food immediately before consumption. MNP are an efficacious intervention for reducing iron deficiency anaemia and filling important nutrient gaps in children 6-23 months of age. As of 2014, 50 countries have implemented MNP programmes including 9 at a national level. This paper provides an overview of a 3-paper series, based on findings from the 'Micronutrient Powders Consultation: Lessons Learned for Operational Guidance' held by the USAID-funded Strengthening Partnerships, Results, and Innovations in Nutrition Globally (SPRING) Project. The objectives of the Consultation were to identify and summarize the most recent MNP programme experiences and lessons learned for operationalizing MNP for young children and prioritize an implementation research agenda. The Consultation was composed of 3 working groups that used the following methods: deliberations among 49 MNP programme implementers and experts, a review of published and grey literature, questionnaires, and key informant interviews, described in this overview. The following articles summarize findings in 3 broad programme areas: planning, implementation, and continual programme improvement. The papers also outline priorities for implementation research to inform improved operationalization of MNP. [ABSTRACT FROM AUTHOR]

Continual course correction during implementation of nutrition programmes is critical to address factors that might limit coverage and potential for impact. Programme improvement requires rigorous scientific inquiry to identify and address implementation pathways and the factors that affect them. Under the auspices of 'The Micronutrient Powders Consultation: Lessons Learned for Operational Guidance,' 3 working groups were formed to summarize experiences and lessons across countries regarding micronutrient powder (MNP) interventions for young children. This paper focuses on how MNP interventions undertook key elements of programme improvement, specifically, the use of programme theory, monitoring, process evaluation, and supportive supervision. Methods included a review of published and grey literature, interviews with key informants, and deliberations throughout the consultation process. We found that although much has been written and published about the use of monitoring and process evaluation to inform MNP interventions at small scale, there has been little formal documentation of lessons for the transition from pilot to scaled implementation. Supervision processes and experiences are not documented, and to our knowledge, there is no evidence of whether they have been effective to improve implementation. Improving the efficiency and effectiveness of interventions requires identification of critical indicators for detecting implementation challenges and drivers of impact, integration with existing programmes and systems, strengthened technical capacity, and financing for implementation of effective monitoring systems. Our understanding of programme improvement for MNP interventions is still incomplete, especially outside of the pilot stage, and we propose a set of implementation research questions that require further investigation.

Abstract: ‘Implementation research in nutrition’ is an emerging area of study aimed at building evidence‐based knowledge and sound theory to design and implement programs that will effectively deliver nutrition interventions. This paper describes some of the basic features of ethnography and illustrates its applications in components of the implementation process. We review the central purpose of ethnography, which is to obtain the emic view – the insider's perspective – and how ethnography has historically interfaced with nutrition. We present examples of ethnographic studies in relation to an analytic framework of the implementation process, situating them with respect to landscape analysis, formative research, process evaluation and impact evaluation. These examples, conducted in various parts of the world by different investigators, demonstrate how ethnography provided important, often essential, insights that influenced programming decisions or explained programme outcomes. Key messages Designing, implementing and evaluating interventions requires knowledge about the populations and communities in which interventions are situated, including knowledge from the ‘emic’ (insider's) perspective. Obtaining emic perspectives and analysing them in relation to cultural, economic and structural features of social organisation in societies is a central purpose of ethnography. Ethnography is an essential aspect of implementation research in nutrition, as it provides important insights for making decisions about appropriate interventions and delivery platforms; determining how best to fit aspects of programme design and implementation into different environmental and cultural contexts; opening the ‘black box’ in interventions to understand how delivery and utilisation processes affect programme outcomes or impacts; and understanding how programme impacts were achieved, or not.

Abstract: The few available studies of programme effectiveness in nutrition find that programmes are less effective than would be predicted from the efficacy trials that are the basis for evidence‐based programming. Some of these are due to gaps in utilisation within households. To a greater extent, these gaps can be attributed to problems in programme design and implementation. ‘Implementation research in nutrition’ is an emerging area of study aimed at addressing this problem, by building an evidence base and a sound theory to design and implement programmes that will effectively deliver nutrition interventions. The purpose of this supplement to Maternal & Child Nutrition is to contribute to this growing area of implementation research. The series of papers presented and the reflections for policymaking and programmes, combined with the reflections on the application of ethnography to this area of inquiry, illustrate the value of systematic research undertaken for the purpose of supporting the design of nutrition interventions that are appropriate for the specific populations in which they are undertaken. © 2015 Blackwell Publishing Ltd [ABSTRACT FROM AUTHOR]

Pre-pregnancy overweight and obesity is associated with shorter breastfeeding ( BF) duration. Whether pre-pregnancy overweight and obesity is associated with other aspects of infant and young child feeding ( IYCF) has not been investigated. We used data from 370 children born January 1999- September 2001 in a semi-urban community in Morelos, Mexico, where information on how they were fed was available at 1, 3, 6, 9, 12, 18 and 24 months of age. We modified the World Health Organization's dietary diversity indicator to assess the quality of the complementary foods. An index that included BF, quality of complementary foods and other behaviours was constructed to measure IYCF. We used survival analysis to examine the association of pre-pregnancy body mass index ( pBMI) category and BF duration and mixed models for quality of complementary food and IYCF index. Mean maternal pBMI was 24.4 ± 4.1; 31% were overweight, and 9% were obese. pBMI was not associated with BF duration. Quality of complementary food improved over time (6 months, 1.3 ± 1.3; 24 months, 3.8 ± 1.04). Compared with normal-weight women, overweight and obese women were more likely to feed from more food groups (0.24 ± 0.11 point, P = 0.03), but this did not improve diet diversity from 6 to 24 months. IYCF index decreased throughout follow-up (1 month, 7.8 ± 2.4; 24 months, 5.5 ± 1.8), and pBMI was not associated with IYCF (−0.11 ± 0.13 point, P = 0.4). We conclude that heavier women were not engaging in IYCF behaviours that were distinct from those of normal-weight women from 1 to 24 months post-partum. [ABSTRACT FROM AUTHOR]

The accurate estimation of gestational age in field studies in rural areas of developing countries continues to present difficulties for researchers. Our objective was to determine the best method for gestational age estimation in rural Guatemala. Women of childbearing age from four communities in rural Guatemala were invited to participate in a longitudinal study. Gestational age at birth was determined by an early second trimester measure of biparietal diameter, last menstrual period (LMP), the Capurro neonatal examination and symphysis-fundus height (SFH) for 171 women–infant pairs. Regression modelling was used to determine which method provided the best estimate of gestational age using ultrasound as the reference. Gestational age estimated by LMP was within ±14 days of the ultrasound estimate for 94% of the sample. LMP-estimated gestational age explained 46% of the variance in gestational age estimated by ultrasound whereas the neonatal examination explained only 20%. The results of this study suggest that, when trained field personnel assist women to recall their date of LMP, this date provides the best estimate of gestational age. SFH measured during the second trimester may provide a reasonable alternative when LMP is unavailable. [ABSTRACT FROM AUTHOR]

Micronutrient powders (MNP) are recommended by the World Health Organization as an effective intervention to address anaemia in children. A formative process evaluation was conducted to assess the viability of a model using free vouchers in two districts of Mozambique to deliver MNP and motivate adherence to recommendations regarding its use. The evaluation consisted of (a) an examination of programme outcomes using a cross‐sectional survey among caregivers of children 6–23 months (n = 1,028) and (b) an ethnographic study to investigate delivery experiences and MNP use from caregiver perspectives (n = 59), programme managers (n = 17), and programme implementers (n = 168). Using a mixed methods approach allowed exploration of unexpected programme outcomes and triangulation of findings. The survey revealed that receiving a voucher was the main implementation bottleneck. Although few caregivers received vouchers (11.5%, CI [9.7, 13.6]), one‐fourth received MNP by bypassing the voucher system (26.3%, CI [23.6, 29.0]). Caregivers' narratives indicated that caregivers were motivated to redeem vouchers but encountered obstacles, including not knowing where or how to redeem them or finding MNP were not available at the shop. Observing these challenges, many programme implementers redeemed vouchers and distributed MNP to caregivers. Virtually, all caregivers who received MNP reported ever feeding it to their child. This study's findings are consistent with other studies across a range of contexts suggesting that although programmes are generally effective in motivating initial use, more attention is required to improve access to MNP and support continued use.

A theory‐driven evaluation was conducted to assess performance of a trial to deliver micronutrient powder (MNP) through the Ethiopian Ministry of Health. We adapted an approach to coverage assessment, originally developed to identify bottlenecks in health service delivery, to examine sequential program outcomes and their correlates using cross‐sectional survey data of caregivers of children 6–23 months (N = 1915). Separate multivariable Poisson regression models were used to estimate adjusted risk ratios of conceptually relevant determinants of coverage and adherence. Caregivers of children >11 months were more likely to have received MNP than caregivers of younger infants, yet children 12–17 months were 32% (P < 0.001) and children 18–23 months 38% (P < 0.001) less likely to have been fed MNP in the 14 days preceding the survey than children 6–11 months. Among caregivers who initiated feeding MNP, the most frequently reported reasons for discontinuing use were not obtaining additional supply (36.1%) and perceived child rejection of food with MNP (22.9%). For each additional time a caregiver met with frontline workers in the 3 months preceding the survey, they were 13% more likely to have recently fed MNP (P < 0.001). Caregivers' perception that MNP produced positive changes in children was associated with a 14% increase in the likelihood of having recently fed it (P < 0.001). These results emphasize the importance of counselling for MNP and infant and young child feeding for initial use and the importance of multiple contacts with frontline workers for continued use.

As part of a formative evaluation of a micronutrient powder (MNP) trial in Ethiopia that was organized according to a programme impact pathway model, we conducted in‐depth focused ethnographic interviews with caregivers of children between 6 and 23 months who had accepted to try "Desta," a locally branded MNP. After stratification into two subgroups by child age, respondents were randomly selected from lists of caregivers who had received MNP from government health workers between 1 and 3 months prior to the interview date. Thirty women who were either currently giving Desta to their child ("continuing users," n = 14) or had stopped feeding Desta ("noncontinuing users," n = 16) were purposefully recruited from both urban and rural areas in the two different regions where the trial was conducted. Interviews were recorded, transcribed and translated, and coded for both emerging and prespecified themes. On the basis of identifiable components in the caregiver adherence process, this paper focuses exclusively on factors that facilitated and inhibited "appropriate use" and "continued use." For "appropriate use," defined as the caregiver preparing and child consuming MNP as directed, we identified four common themes in caregiver narratives. With respect to "continued use," the caregiver providing and child consuming the minimum number of MNP sachets over a recommended time period, our interviews spontaneously elicited five themes. We also examined caregivers' perceptions related to problems in obtaining refills. Attention to caregivers' perspectives reflected in their narratives offers opportunities to improve MNP utilization in Ethiopia, with potential application in other social and cultural settings.

- Abstract
The objective of this study was to assess the acceptability of three nutritional supplements among pregnant and lactating women: sprinkles, fortified foods and tablets. This is the first study of acceptability of Sprinkles in any adult population. All participants were beneficiaries of the Oportunidades program and came from urban, rural and indigenous communities in Mexico. Women were surveyed about the acceptability of these three supplements (n=268). Furthermore, semi-structured interviews were conducted with women about their knowledge, perceptions, preferences, and preferred education delivery mechanisms (n=40). All participants recognized health benefits of the three supplements. However, tablets were the first choice because of their convenience (no mixing with food or preparation needed) and the absence of perceptible taste or smell. Women disliked that Sprinkles modified the taste and consistency of food and experienced the portion sizes of the fortified food as too large. Our results suggest that most women interviewed preferred tablets irrespective of residence and physiological status (pregnant/lactating). The Oportunidades program financed this study and holds the rights to the data presented. [ABSTRACT FROM AUTHOR]

Objective: To assess the ability of anthropometric measurements to identify young women at risk of developing diabetes, hypertension and heart disease in the future and to compare cut-offs established with ROC curves to those in the literature. Measurements/Methods: The ability of anthropometric measures of fatness and fat distribution (BMI, skinfolds, waist circumference (WC), waist-to-hip ratio, conicity index, abdominal volume index) to predict risk of future disease (pre-diabetes, pre-hypertension, hypertriglyceridemia, or a combination of risk factors) was assessed using Receiver Operating Characteristics (ROC) analysis. Results: Mean age of the 729 women was 29.6&5.4 yr and mean BMI 27.74±4.5 kg/m². There were no significant differences in the area under the ROC curve for BMI, WC abdominal volume index or summed skinfolds for any of the four outcomes. However, these indices performed significantly better than waist-to-hip ratio or conicity index (p<0.05). The BMI cut-off points that maximized sensitivity and specificity for the four outcomes were 27.7-28.4 kg/m⊃2, and for WC were 89.3-91.2 mm. To detect 90% of the cases of any metabolic alteration, the necessary BMI cut-off was 26.1 kg/m². Younger women (< 25 yr) were at great risk than older women for a given BMI increment (p < 0.05).
