Background: 2015 saw the largest annual spike of mortality rates in England in almost 50 years. We examine whether these changes in mortality rates are associated with an indicator of poor functioning of health and social care: delay in hospital discharges., Methods: Office for National Statistics monthly data of death counts and mortality rates for the period August 2010-March 2016 were compared with delays in discharges from National Health Service (NHS) England data on transfers of care for acute and non-acute patients in England. Autoregressive Integrated Moving Average regression models were used in the analysis., Results: We estimate that each additional day an acute admission was late being discharged was associated with an increase in 0.394 deaths (95% CIs 0.220 to 0.569). For each additional acute patient delayed being discharged, we found an increase of 7.322 deaths (95% CIs 1.754 to 12.890). Findings for non-acute admissions were mixed., Conclusion: The increased prevalence of patients being delayed in discharge from hospital in 2015 was associated with increases in mortality, accounting for up to a fifth of mortality increases. Our study provides evidence that a lower quality of performance of the NHS and adult social care as a result of austerity may be having an adverse impact on population health., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Background: Since 2008, use of food banks has risen sharply in the UK; however, evidence on the epidemiology of UK food insecurity is sparse. The aim of this study was to describe the trajectory of common mental disorder across the pre-pregnancy, pregnancy and postnatal period for food secure compared with food insecure women., Methods: Data from the Born in Bradford (BiB) cohort, the nested BiB1000 study and primary care records were linked based on National Health Service (NHS) numbers. Data linkage was completed for 1297, and primary care records were available from 18 months prior to 40 months after birth of the cohort child. Incidence rates of common mental disorders per 1000 patient years at risk were compared between food secure and insecure women, and for Pakistani compared with white British women, in 10 6-month periods around pregnancy. Poisson regression was used to calculate incidence rate ratios, adjusted for ethnicity and exposure., Results: Food insecurity was significantly associated with an increased risk of common mental disorder before and during pregnancy (incidence rate ratio 1.9, 95% confidence interval 1.3 to 2.8, p=0.001) and after giving birth (incidence rate ratio 1.3, 95% confidence interval 1.0 to 1.7, p=0.029)., Conclusions: Our study shows that food insecure women have worse mental health than food secure women, and that this difference is most pronounced for white British pregnant women. These findings provide evidence for concerns expressed by public health experts that food insecurity may become the next public health emergency., (Published by the BMJ Publishing Group Limited.

Background: Maternal smoking during pregnancy has been consistently associated with disruptive behaviour in male offspring; however, results for girls are inconsistent and little is known about emergent patterns in young children. Additionally, it is unclear whether maternal smoking is independently associated in offspring with hyperactivity-inattention or only when it co-occurs with conduct problems. Further, few studies have controlled for a broad range of maternal psychosocial problems., Methods: Associations between self-reported smoking in pregnancy and maternal reports of externalising behaviour were analysed in more than 13 000 3-year-old boys and girls in the UK Millennium Cohort Study. Conduct and hyperactivity-inattention problems were assessed using the Strength and Difficulties Questionnaire., Results: Boys whose mothers persistently smoked throughout pregnancy were at significant risk of conduct and hyperactivity-inattention problems compared with sons of non-smokers: the effect was stronger for heavy smokers. After excluding children with co-occurring problems, conduct-only problems remained a significant risk for sons of heavy smokers, OR 1.92 (95% CI 1.29 to 2.86); and hyperactivity-inattention only for sons of light or heavy smokers, OR 1.79 (95% CI 1.27 to 2.51) and 1.64 (1.10 to 2.46). Daughters of light or heavy smokers were at significant risk of conduct-only problems, OR 1.73 (95% CI 1.14 to 2.61) and 1.73 (1.06 to 2.83). Relative to non-smokers, daughters of pregnancy quitters had significantly reduced odds of having conduct 0.61(0.39 to 0.97) or co-occurring problems 0.26(0.08 to 0.82), although only 79 and 20 girls met these criteria, respectively. All findings were robust to controlling for key social and psychosocial factors., Conclusions: Associations between maternal smoking during pregnancy and disruptive behaviour in 3-year-old children vary by sex, smoking status and whether or not conduct or hyperactivity problems occur together or separately.

Background: Although pregnancy is a time when women have increased motivation to quit smoking, approximately half of female smokers persist in smoking throughout their pregnancies. Persistent pregnancy smokers are known to be more nicotine dependent and to have greater sociodemographic disadvantage. Less is known about the psychosocial context of persistent pregnancy smokers and factors that distinguish them from pregnancy quitters., Methods: A cross-sectional study was conducted within the UK Millennium Cohort Study. Participants were 18 225 women, including 13.3% quitters, 12% light smokers and 8% heavy smokers. Data were collected when the infants were 9 months old. Maternal psychosocial problems were assessed in three domains: interpersonal, adaptive functioning and health-related behaviours., Results: In general, psychosocial problems in all domains increased across the pregnancy smoking continuum (non-smoker, quitter, light smoker, heavy smoker). All three psychosocial domains added incremental utility to prediction of pregnancy smoking status, after adjustment for sociodemographic risk., Conclusion: Problems in multiple psychosocial domains systematically distinguish women along a pregnancy smoking gradient, with heavy smokers having the most problematic psychosocial context. This subgroup of pregnant smokers is unlikely to be able to benefit from usual-care antenatal cessation interventions, which rely on women's capacity for self-initiation, self-control and social resources. Consideration should be given to tiered interventions that provide more intensive and targeted interventions to pregnant women unable to quit with usual care.

Background: Smoking during pregnancy has been consistently associated with risk of problem behaviour in offspring. There is debate about whether this association reflects a teratological effect or is a marker for problematic maternal characteristics. We test these "competing" hypotheses by examining whether (1) exposure is associated with an early risk pathway by testing its association with infant temperamental difficultness, and (2) whether pregnancy quitting is associated with an early protective pathway, testing its association with easy infant temperament., Methods: We used the 9-month-old sweep of the Millennium Cohort Study, a cohort of over 18,000 infants born in 2000-2. Mothers were classified as pregnancy non-smokers, quitters and light or heavy smokers. Temperamental positive mood, receptivity to novelty and regularity were assessed with the Carey Infant Temperament Scale., Results: Pregnancy quitters had infants with the highest scores of easy temperament and heavy smokers had infants with the lowest scores (F = 28.51, p<0.001). Pregnancy smoking also predicted difficult temperament: heavy smoking was associated with increased risk of low positive mood (OR = 1.17, p = 0.09). In contrast, pregnancy quitting exerted a protective effect with decreased risk of distress to novelty (OR = 0.79, p<0.01) and irregularity (OR = 0.89, p = 0.02) in these infants., Conclusions: Pathways from pregnancy smoking to offspring behaviour are complex and multi-determined. These findings suggest that both exposure and maternal characteristics associated with pregnancy smoking status contribute to offspring behavioural patterns. Research that characterises differences between quitters and persistent smokers and examines the role of these differences in prediction of early vulnerabilities and problems in adaptation over time will be important for elucidating these pathways.

Objectives: To see if obesity, deaths from diabetes, and daily calorie intake are associated with income inequality among developed countries., Design: Ecological study of 21 developed countries.Countries: Countries were eligible for inclusion if they were among the top 50 countries with the highest gross national income per capita by purchasing power parity in 2002, had a population over 3 million, and had available data on income inequality and outcome measures., Main Outcome Measures: Percentage of obese (body mass index >30) adult men and women, diabetes mortality rates, and calorie consumption per capita per day., Results: Adjusting for gross national per capita income, income inequality was positively correlated with the percentage of obese men (r = 0.48, p = 0.03), the percentage of obese women (r = 0.62, p = 0.003), diabetes mortality rates per 1 million people (r = 0.46, p = 0.04), and average calories per capita per day (r = 0.50, p = 0.02). Correlations were stronger if analyses were weighted for population size. The effect of income inequality on female obesity was independent of average calorie intake., Conclusions: Obesity, diabetes mortality, and calorie consumption were associated with income inequality in developed countries. Increased nutritional problems may be a consequence of the psychosocial impact of living in a more hierarchical society.

Study Objective: Research shows that neighbourhood socioeconomic factors are associated with preterm delivery. This study examined whether cigarette smoking and individual socioeconomic factors modify the effects of neighbourhood factors on preterm delivery., Design: Case-control study., Setting: Moffit Hospital in San Francisco, California., Participants: 417 African American and 1244 white women, including all preterm and a random selection of term deliveries 1980-1990, excluding non-singleton pregnancies, congenital anomolies, induced deliveries, and women transported for special care. US census data from 1980 and 1990 were used to characterise the women's neighbourhoods, defined as census tracts., Results: Cigarette smoking increased the risk of preterm delivery among both African American (OR=1.77, 95% confidence intervals (CI) (1.12 to 2.79)) and white women (OR=1.25, 95% CI (1.01 to 1.55)). However, cigarette smoking did not attenuate or modify the association of neighbourhood factors with preterm delivery. Among African American women, having public insurance modified the relation between neighbourhood unemployment and preterm delivery; among women without public insurance, the risk of preterm delivery was low in areas with low unemployment and high in areas with high unemployment, while among women with public insurance the risk of preterm delivery was highest at low levels of neighbourhood unemployment., Conclusions: Cigarette smoking was associated with preterm delivery, especially among African Americans. Adverse neighbourhood conditions had an influence on preterm delivery beyond that of cigarette smoking. The effects of some neighbourhood characteristics were different depending on individual socioeconomic status. Examining socioeconomic and behavioural/biological risk factors together may increase understanding of the complex causes of preterm delivery.

Purpose: Interest in the effects of neighbourhood or local area social characteristics on health has increased in recent years, but to date the existing evidence has not been systematically reviewed. Multilevel or contextual analyses of social factors and health represent a possible reconciliation between two divergent epidemiological paradigms-individual risk factor epidemiology and an ecological approach., Data Sources: Keyword searching of Index Medicus (Medline) and additional references from retrieved articles., Study Selection: All original studies of the effect of local area social characteristics on individual health outcomes, adjusted for individual socioeconomic status, published in English before 1 June 1998 and focused on populations in developed countries., Data Synthesis: The methodological challenges posed by the design and interpretation of multilevel studies of local area effects are discussed and results summarised with reference to type of health outcome. All but two of the 25 reviewed studies reported a statistically significant association between at least one measure of social environment and a health outcome (contextual effect), after adjusting for individual level socioeconomic status (compositional effect). Contextual effects were generally modest and much smaller than compositional effects., Conclusions: The evidence for modest neighbourhood effects on health is fairly consistent despite heterogeneity of study designs, substitution of local area measures for neighbourhood measures and probable measurement error. By drawing public health attention to the health risks associated with the social structure and ecology of neighbourhoods, innovative approaches to community level interventions may ensue.
