BACKGROUND: In the USA, states can set higher minimum wages than the federal government. We investigated the association between state minimum wages and racial/ethnic inequities in food insecurity. METHODS: Household-level food insecurity and sociodemographic data were obtained from the cross-sectional Current Population Survey 2015-2019 (n=189 665 households) and merged by state and year with minimum wage and cost-of-living data obtained from the US Department of Labor and US Bureau of Economic Analysis, respectively...

BACKGROUND: The transition to retirement is a significant turning point in life, which may lead to changes in food habits. OBJECTIVE: To examine changes in red meat, fish, vegetables and fruit consumption during the retirement transition and whether these changes vary between sociodemographic groups. METHODS: The data were from the Whitehall II study, a cohort of 10 308 British civil servants aged 35-55 years at study induction (1985-1988)...

BACKGROUND: Alcohol misuse is a major public health issue. Understanding factors that contribute to alcohol misuse or risky drinking behaviour is important for policy. This study examined if crime rates in the neighbourhood (postcode) where a person lives influences their likelihood of engaging in risky drinking behaviour. We further explored social capital and mental health as channels through which neighbourhood crime influences risky drinking behaviour. METHODS: Using 18 waves of household longitudinal data from the Household, Income and Labour Dynamics in Australia Survey for the period 2002 to 2019 merged with official police statistics on neighbourhood crime rates, we adopted fixed-effect regression models that allow us to address concerns relating to endogenous sorting of participants as well as omitted variable bias...

BACKGROUND: Unpaid carers deliver critical social care. We aimed to examine differences by ethnicity in (1) profiles of unpaid caring and (2) associations between caring and physical and mental health trajectories. METHODS: We used 10 waves of data from 47 015 participants from the UK Household Longitudinal Study (2009-2020). Our outcomes were 12-item Short Form Health Survey physical and mental component scores. We performed bivariate comparison of profiles of caring by ethnicity...

The recent paper by Dunn et al showed that the positive relationship between US state-level income inequality and mortality was small in the 1950s, rose to a large value around 1990 but had largely disappeared by 2019. We consider these findings in the context of the mechanisms that have been advanced for reasons why a positive relationship might be expected, and in relation to studies using alternative methods included in systematic reviews that fail to confirm an independent inequality/mortality relationship...

BACKGROUND: The association between change in high-sensitivity cardiac troponin T (hs-cTnT) and stroke risk in the general population remains unknown. We aimed to assess the association of a 6-year change in hs-cTnT with incident stroke and its subtypes in the general American adult population. METHODS: 8675 middle-aged adults without prevalent cardiovascular disease from the Atherosclerosis Risk in Communities study were included. Hs-cTnT was measured at two time points (visits 2 and 4), 6 years apart...

BACKGROUND: Diet is an important risk factor for cardiovascular disease and shows well-established socioeconomic patterning among adults. However, less clear is how socioeconomic inequalities in diet develop across the life course. This study assessed the associations of early adulthood socioeconomic trajectories (SETs) with adult diet quality, adjusting for childhood socioeconomic position (SEP) and testing for mediation by adulthood SEP. METHODS: Participants from the 1970 British Cohort Study with socioeconomic data in early adulthood were included (n=12 434)...

BACKGROUND: Little is known about education-related inequalities in late-life disability. Here, we use individual-level register data on the receipt of the Austrian long-term care allowance (ALTCA) to assess education-related inequalities in the duration of late-life disability. METHODS: In this retrospective mortality follow-back study, we analyse receipt of ALTCA, a universal cash benefit based on physician-assessed disability in activities of daily living, during the last 5 years of life among all decedents aged 65 years and over from 2020 in Austria (n=76 772)...

BACKGROUND: Structural racism's influence on workforce policies and practices presents possible upstream targets for assessing and reducing racial health disparities. This study is the first to examine workforce racial diversity in association with racial disparities in cardiovascular disease (CVD) outcomes. METHODS: This retrospective cohort study of 39 693 hourly autoworkers from three Michigan automobile plants, includes 75 years of follow-up (1941-2015)...

BACKGROUND: Prior studies have shown a positive relationship between income inequality and population-level mortality. This study investigates whether the relationship between US state-level income inequality and all-cause mortality persisted from 1989 to 2019 and whether changes in income inequality were correlated with changes in mortality rates. METHODS: We perform repeated cross-sectional regressions of mortality on state-level inequality measures (Gini coefficients) at 10-year intervals...

BACKGROUND: Evidence suggests historical redlining shaped the built environment and health outcomes in urban areas. Only a handful of studies have examined redlining's association with air pollution and adverse birth outcomes in New York City (NYC). Additionally, no NYC-specific studies have examined the impact of redlining on birth weight. METHODS: This longitudinal cohort study analysed data from the National Institute of Health Environmental Influences on Child Health Outcomes Programme to investigate the extent to which maternal residence in a historically redlined neighbourhood is associated with fine particulate matter (PM2...

BACKGROUND: Material disadvantage is associated with poor health, but commonly available area-based metrics provide a poor proxy for it. We investigate if a measure of material disadvantage could be constructed from UK primary care electronic health records. METHODS: Using data from Clinical Practice Research Datalink Aurum (May 2022) linked to the 2019 English Index of Multiple Deprivation (IMD), we sought to (1) identify codes that signified material disadvantage, (2) aggregate these codes into a binary measure of material disadvantage and (3) compare the proportion of people with this binary measure against IMD quintiles for validation purposes...

BACKGROUND: Childhood infection might be associated with adverse child development and neurocognitive outcomes, but the results have been inconsistent. METHODS: Two population-based record-linkage cohorts of all singleton children born at term in New South Wales, Australia, from 2001 to 2014, were set up and followed up to 2019 for developmental outcome (N=276 454) and school performance (N=644 291). The primary outcome was developmentally high risk (DHR) at age 4-6 years and numeracy and reading below the national minimum standard at age 7-9 years...

BACKGROUND: Socioeconomic status (SES) is associated with many chronic diseases, indicators of senescence and mortality. However, the changing salience of SES in the prediction of adult health is not well understood. Using mRNA-seq abundance data from wave V of the National Longitudinal Study of Adolescent to Adult Health (Add Health), we examine the extent to which SES across the early life course is related to gene expression-based signatures for chronic diseases, senescence and inflammation in the late 30s...

BACKGROUND: This study investigates the association between frailty and mortality in Eastern European populations, which remains largely unexplored compared with Western Europe. The aim is to assess the risk of all-cause and cardiovascular mortality associated with varying levels of frailty. METHODS: A prospective multicentre cohort study was conducted, involving random population samples from the Czech Republic, Poland and Lithuania. The baseline survey (2002-2005) included 26 746 individuals aged 45-69 years, with an average follow-up of 13 years...

BACKGROUND: Longitudinal studies can generate valuable scientific knowledge, but can be compromised by systematic attrition. Previous research shows that sociodemographic characteristics (eg, ethnicity, age, educational level, socioeconomic circumstances) are associated with attrition rates. However, little is known about whether these characteristics differ by ethnicity, and how this impacts cohort retention strategies. METHODS: Using antenatal to 12-year data from the Growing Up in New Zealand birth cohort study (N=6743), we examined transversal response rates by ethnicity (Māori, Pacific, Asian, European), used sequence analysis and cluster analysis to identify unique longitudinal response patterns, and binary logistic regression to examine ethnic-specific sociodemographic characteristics associated with these response patterns...

BACKGROUND: Women sex workers face substantial health inequities due to structural barriers including criminalisation and stigma. Stigma has been associated with HIV-related inequities among marginalised populations, however, we know less about the impacts of sex work-specific occupational stigma on HIV/sexually transmitted infection (STI) risk among women sex workers. Given these research gaps and the disproportionate burden of stigma faced by sex workers, we evaluated the association between sex work occupational stigma and recent inconsistent condom use with clients, over an 8-year period (2014-2022)...

BACKGROUND: The association of maternal cigarette smoking during pregnancy with severe neonatal morbidity (SNM) is still inconclusive. We aimed to examine the associations of the timing and the intensity of maternal cigarette smoking with infant SNM in the USA. METHODS: We used birth certificate data of 12 150 535 women aged 18-49 years who had live singleton births from the 2016-2019 US National Vital Statistics System. Women self-reported the daily number of cigarettes they consumed before pregnancy and in each trimester of pregnancy...

BACKGROUND: Research has long documented the increased emergency department usage by persons who are homeless compared with their housed counterparts, as well as an increased prevalence of infectious diseases. However, there is a gap in knowledge regarding the comparative treatment that persons who are homeless receive. This study seeks to describe this potential difference in treatment, including diagnostic services tested, procedures performed and medications prescribed. METHODS: This study used a retrospective, cohort study design to analyse data from the 2007-2010 United States National Hospital Ambulatory Medical Care Survey database, specifically looking at the emergency department subset...

BACKGROUND: Child mental health has become an increasingly important issue in the UK, especially in the context of significant welfare reforms. Universal Credit (UC) has introduced substantial changes to the UK's social security system, significantly impacting low-income families. Our aim was to assess the effects of UC's introduction on children's mental health for families eligible for UC versus a comparable non-eligible sample. METHODS: Using Understanding Society data from 5806 observations of 4582 children (aged 5 or 8 years) in Great Britain between 2012 and 2018, we created two groups: children whose parents were eligible for UC (intervention group) and children whose parents were ineligible for UC (comparison group)...
