BACKGROUND: Past research suggests that adolescents who witness violence are at risk of adjustment problems. However, few studies have implemented a longitudinal design and have accounted for direct experiences of victimisation and other major confounders. This prospective study examines the relationship between witnessing school violence and subsequent impairment and whether such associations depend on the kind of violence witnessed. METHODS: 3936 adolescents from Quebec (Canada) were followed from ages 12 through 15 years...

BACKGROUND: International evidence indicates relationships between pre-pregnancy body mass index (BMI) and breastfeeding behaviours. This study aims to assess associations between key points in the breastfeeding trajectory (initiation, early cessation and longevity) and pre-pregnancy BMI in a recent, nationally representative British cohort. It also aims to explore in the British context potential moderation by mothers' ethnic group. METHODS: The sample comprises 17 113 mothers from the UK Millennium Cohort Study who have information on pre-pregnancy BMI...

BACKGROUND: Socioeconomic status (SES) is a fundamental contributor to health; however, limited research has examined sexual orientation differences in SES. METHODS: 2008-2009 data from 14 051 participants (ages 24-32 years) in the US-based, representative, National Longitudinal Study of Adolescent to Adult Health were analysed using multivariable regressions that adjusted for age, race-ethnicity, childhood SES, urbanicity and Census region, separately for females and males...

BACKGROUND: Due to the sustained increases in life expectancy over the past half century, the elderly today will receive supports from their children for a longer period than ever before. Therefore, understanding the spillover effects of children's socioeconomic status on parents' health becomes increasingly important for both scholars and policy makers. METHODS: The Ordinary Least Squares regression is applied to the China Health and Retirement Longitudinal Study 2011, a national representative dataset including approximately 10 000 households and 17 600 middle-aged and elderly respondents...

BACKGROUND: Childhood overweight/obesity has been associated with environmental context, such as green space, gardens, crime and deprivation. This paper assesses the longitudinal association between environment and body mass index (BMI) for children across the ages of 3-11 years. It also investigates the relationship between environment and child overweight/obesity METHODS: 6001 children from the UK Millennium Cohort Study living in England were analysed. We estimated fixed effects linear and logistic regression models of the association between environment (levels of green space, gardens, crime and deprivation) and BMI/overweight of children at four time points between the ages of 3 and 11...

BACKGROUND: Substantial disparities in life expectancy exist between Chicago's 77 defined community areas, ranging from approximately 69 to 85 years. Prior work in New York City and Boston has shown that community-level racial and economic segregation as measured by the Index of Concentration at the Extremes (ICE) is strongly related to premature mortality. This novel metric allows for the joint assessment of area-based income and racial polarisation. This study aimed to assess the relationships between racial and economic segregation and economic hardship with premature mortality in Chicago...

BACKGROUND: Children who experience parental cancer are at increased risk of developing emotional, social, cognitive and behavioural problems. Our aim was to investigate how experience of parental cancer in childhood or adolescence is associated with primary school achievement, educational attainment and income in early adult life. METHODS: This is a register-linkage, prospective study of children born in Denmark from 1978 through 1999 and their parents. Parental cancer experience before the ages of 15 and 18 was identified in the Danish National Patient Registry...

BACKGROUND: Based on existing studies, there is no conclusive evidence as to whether and why paternal age matters for birth outcomes. METHODS: We used Finnish population registers on 106 652 children born 1987-2000. We first document the unadjusted association between paternal age and the risk of low birth weight (LBW; <2500 g) and preterm birth (<37 weeks' gestation). Second, we investigate whether the unadjusted association is attenuated on adjustment for child's, maternal and parental socioeconomic characteristics...

BACKGROUND: Vitamin C insufficiency occurs across many countries and has been hypothesised to increase risk of various diseases. Few prospective studies with measured circulating vitamin C have related deficiency to disease mortality, particularly in low-income and middle-income countries. METHODS: We randomly selected 948 subjects (473 males and 475 females) aged 53-84 years from a Chinese cohort and measured meta-phosphoric acid-preserved vitamin C concentrations in plasma samples collected in 1999-2000...

BACKGROUND: Literature on health promotion evaluation and public understanding of health suggests the importance of investigating behaviour over time in conjunction with information environment trends as a way of understanding programme impact. We analysed population response to online promotion of an educational tool built by the Ask About Aspirin campaign in the USA to inform people about aspirin as a preventive aid. METHODS: We collected 156 weeks of time series data on audience behaviour, namely use of a self-assessment tool...

BACKGROUND: Adverse childhood socioeconomic status (cSES) predicts higher late-life risk of memory loss and dementia. Veterans of U.S. wars are eligible for educational and economic benefits that may offset cSES disadvantage. We test whether cSES disparities in late-life memory and dementia are smaller among veterans than non-veterans. METHODS: Data came from US-born men in the 1995-2014 biennial surveys of the Health and Retirement Study (n=7916 born 1928-1956, contributing n=38 381 cognitive assessments)...

BACKGROUND: A J-curve association has been demonstrated for blood pressure (BP) and all-cause mortality, but data on longitudinal change of BP and mortality in Chinese population are limited. METHODS: We performed a retrospective cohort study to examine the association between BP (at baseline and longitudinal change) and risk of mortality in Yinzhou District, Ningbo, China, based on the Yinzhou Health Information System. At baseline, a total of 181 352 subjects aged over 18 years with at least one BP examination record were recruited through the Yinzhou Health Information System...

BACKGROUND: Separation from one's child can have significant consequences for parental health and well-being. We aimed to investigate whether parents whose children were placed in care had higher rates of avoidable mortality. METHODS: Data were obtained from the Swedish national registers. Mortality rates among parents whose children were placed in care between 1990 and 2012 (17 503 mothers, 18 298 fathers) were compared with a 1:5 matched cohort of parents whose children were not placed...

BACKGROUND: We explore how mortality is related to unemployment and intragenerational social mobility in Finland. Unemployment and social mobility are two labour market experiences that are largely studied separately, despite the fact that selection processes into unemployment and downward mobility are intertwined. Because both causal and health selection mechanisms may vary depending on the timing of these experiences, we consider heterogeneity by age and economic context. METHODS: We run discrete time event history analysis for death (at age 30-75 years) in two periods (economic recession and growth) and analyse younger and older individuals and men and women separately...

BACKGROUND: Little is known about the effects of physical activity and fitness on sleep timing parameters in adolescence. METHODS: We investigated the development of sleep timing between age 8 and 15 and its association with physical fitness at age 15 in 787 adolescents (408 males, 379 females). Physical fitness was measured using the physical work capacity (PWC) protocol. Information on sport activity was collected at ages 11 and 15. Finally, the contribution of other covariates (sex, body mass index (BMI), parental education and occupational skill level) to the association between sleep parameters and physical fitness was evaluated...

BACKGROUND: Racial discrimination may play a significant role in higher incidence and poorer prognosis of chronic kidney disease among Black individuals. This study set out to investigate the association between racial discrimination and renal function and to estimate the contribution of racial discrimination to existing racial disparities in renal function. METHODS: A cross-sectional analysis using baseline data (2008-2010) of 14 355 participants (35-74 years) in the Brazilian Longitudinal Study of Adult Health cohort study...

BACKGROUND: Previous evidence of an association between body mass index (BMI) and mortality in patients with diabetes was inconsistent. The BMI-mortality association with normal fasting glucose (NFG), impaired fasting glucose (IFG) and prevalent diabetes is still unclear in the Chinese population. METHODS: We analysed data for 17 252 adults from the Rural Chinese Cohort Study during 2007-2008 and followed for mortality during 2013-2014. Participants were classified with NFG, IFG and diabetes according to baseline measurement values of fasting glucose and self-reported diabetes...
