For the first time, a question relating to certain long-term health conditions was asked in the 2021 Australian population census. The conditions included arthritis, asthma, cancer (including remission), dementia (including Alzheimer’s), diabetes (excluding gestational diabetes), heart disease (including heart attack or angina), kidney disease, lung condition (including COPD or emphysema), mental health condition (including depression or anxiety), and stroke. Respondents could indicate either none or any number of these conditions. In this paper, the data on these conditions have been analysed to compare the self-reported prevalence of diseases among the 23.4 million Australians who responded to this question (median age 39 years), of whom 3.2% were Aboriginal and Torres Strait Islander peoples (median age 24 years). Standardised Morbidity Ratios for each disease were calculated for the Aboriginal and Torres Strait Islander peoples by using the relevant age-disease specific morbidity rates for the total population as the ‘standard’. Findings of this research revealed that the prevalence of diseases was much higher among the Aboriginal and Torres Strait Islander peoples compared to the total population. The only exception was cancer, where the rates for the two groups were not much different. Gaps in prevalence of diseases in the two groups generally increased with age. The higher rates among the Aboriginal and Torres Strait Islander peoples emphasise the need for continued action on health equity and the development of more nuanced and focused initiatives to reduce the gaps between the Aboriginal and Torres Strait Islander peoples vis-à-vis the total population of Australia. Findings in this paper were consistent with similar studies (albeit largely surveys) on health of the Indigenous peoples in Canada and the Maoris in New Zealand.

When traditional measures for material conditions are scarce or unreliable, body mass, height, and weight are complements to standard income and wealth measures. A persistent question in welfare studies is the 19th century’s 2nd and 3rd quarter’s stature diminution, a pattern known as the antebellum paradox. However, the question may not be well stated nor experienced equally by women and non-white male samples. The late 19th century’s political Granger, Greenback, and Populist movements may have affected farmer and non-farmer’s net nutrition. Despite 19th and early 20th century US political movements, farmers had greater BMIs, taller statures, and heavier weights than non-farmers. From the 1870s through 1890s, women’s body mass, height, and weight increased relative to men. Individuals of African or mixed European-African descent had heavier weights and greater BMIs than their taller, European-white counterparts, indicating that the traditional antebellum paradox needs to include women and non-European males and weight measures.

Premised on the Developmental Origins of Health and Disease theory and on the limited effectiveness of antenatal interventions, interventions in the preconception period are being conducted to potentially improve intergenerational health and non-communicable disease burdens. The Healthy Life Trajectories Initiative (HeLTI) is an international health research consortium primarily investigating the intergenerational effects of behavioural interventions on obesity via a complex four-phase intervention initiated preconceptionally, through pregnancy, and into early childhood. HeLTI, in partnership with the World Health Organization, aims to generate evidence that will shape health policy focused on preconception as part of a life course approach to population health. It is necessary to ensure that a renewed public health focus on preconception prioritises justice and equity in its framing. This article presents collaborative interdisciplinary work with HeLTI-South Africa. It applies a feminist bioethics methodology, which is empirical, situated, intersectional, and fundamentally concerned with justice, to investigate what South African HeLTI community health workers, or ‘Health Helpers’, who deliver the complex behavioural intervention, think about preconception health and responsibility. Seven semi-structured interviews were conducted with HeLTI-SA Health Helpers, and data were analysed using reflexive thematic analysis. Our findings show that Health Helpers’ perceptions of preconception health and related responsibility were significantly gendered, heteronormative, and concerned with child-bearing intentionality and desires. These themes were inflected with Health Helpers’ perceptions about how attributions of responsibility are shaped by culture, demonstrating the situated nature of epistemologies. Their ideas also highlight how preconception health knowledge can distribute responsibility unjustly. Understanding the contextual impact and relevance of values around responsibility is critical to prospectively design preconception health interventions that promote equity and fairness. This understanding can then be used for effective policy translation, with the goal that public health policy is founded upon contextual responsivity and justice for the public it aims to serve.

Low birth weight (LBW) and preterm birth (PTB) are primary factors contributing to morbidity and mortality among children aged under 5, resulting in a range of short- and long-term health consequences worldwide. Among the various risk factors, ambient air pollution poses a significant environmental risk and is a key determinant of child health. The prevalence of LBW and PTB among under 5 children sampled from the NFHS-5, 2019–2021, was combined with monthly PM2.5 data (2013–2021) obtained from the Atmospheric Composition Analysis Group at Washington University. Multivariable logistic regression models were used, and a stratified analysis was applied to understand the potential effect modifiers in LBW and PTB. Further, the geographical variation of LBW and PTB spatial autocorrelation (Moran’s I) was used. Geographically weighted regression and ordinary least square spatial regression were used to identify the spatial heterogeneity associated with selected variables. The study comprises a total of 208,181 under 5 children. Out of these children, the LBW rate was 17.41%, and the rate of PTB was 12.42%. The in-utero exposure to the mean concentration of PM2.5 was 56.01 μg/m3. The odds of suffering from LBW showed a non-linear shift when PM2.5 levels rose from the first octile (<28.02 μg/m3) to the last octile (>93.84 μg/m3) (adjusted odds ratio (AOR): 1.06, 95% CI: 1.01–1.12). While comparing the first octile of exposure to PM2.5 (>93.84 μg/m3) to the last octile, there was a 52% more likelihood of having PTB (AOR: 1.52, 95% CI: 1.43–1.61) after accounting for all relevant factors. These findings highlight the urgent need for a thorough strategy to control the air quality in India. Further, to reduce adverse birth outcomes, longitudinal studies and other co-pollutants can consider assessing the possible mechanisms mediating the relationship between maternal exposure and ambient air pollution.

Spousal age differences are highest in Sub-Saharan Africa, where trends in age at first marriage indicate an increase for both men and women. However, the net outcome for spousal age difference is difficult to predict without explicit analysis of these distributions. This study examines differentials in spousal age for women in first union. Further, it examines differences within population sub-groups and across countries, focusing on the influence of age at marriage and educational attainment. The analysis pools 144 survey datasets from the Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) conducted between 1980 and 2020 in 34 countries. OLS regression analysis was used to predict the spousal age difference at marriage with five-year cohorts used to study time trends. The analysis finds a decline of 1.7 years in the spousal age difference at first marriage between the earliest (1980–1984) and most recent (2014–2019), indicating that there has been minimal reduction in age at first marriage over four decades, despite rising ages at marriage for females. Increasing age at first marriage and educational attainment of women partly explain the decline observed over time.
