RESUMEN
STUDY QUESTION: Are women's reproductive factors associated with physical frailty and comprehensive frailty in middle-age and later life? SUMMARY ANSWER: Early menarche at <13 years, age at menopause <45 years, surgical menopause, experiencing miscarriage and a shorter reproductive period of <35 years were associated with increased odds of frailty, while having two or three children was related to decreased likelihood of frailty. WHAT IS KNOWN ALREADY: Evidence has shown that women are frailer than men in all age groups and across different populations, although women have longer lifespans. Female-specific reproductive factors may be related to risk of frailty in women. STUDY DESIGN SIZE DURATION: A population-based cross-sectional study involved 189 898 women from the UK Biobank. PARTICIPANTS/MATERIALS SETTING METHODS: Frailty phenotype and frailty index were used to assess physical frailty and comprehensive frailty (assessed using 38 health indicators for physical and mental wellbeing), respectively. Multivariable logistic regression models were used to estimate odds ratios (ORs) and 95% CI between reproductive factors and likelihood of physical frailty and comprehensive frailty. Restricted cubic spline models were used to test the non-linear associations between them. In addition, we examined the combined effect of categorized age at menopause and menopause hormone therapy (MHT) on frailty. MAIN RESULTS AND THE ROLE OF CHANCE: There was a J-shape relationship between age at menarche, reproductive period, and frailty; age at menarche <13 years and >16 years, and reproductive period <35 years or >40 years were all associated with increased odds of frailty. There was a negative linear relationship between menopausal age (either natural or surgical) and odds of frailty. Surgical menopause was associated with 30% higher odds of physical frailty (1.34, 1.27-1.43) and 30% higher odds of comprehensive frailty (1.30, 1.25-1.35). Having two or three children was linked to the lowest likelihood of physical frailty (0.48, 0.38-0.59) and comprehensive frailty (0.72, 0.64-0.81). Experiencing a miscarriage increased the odds of frailty. MHT use was linked to increased odds of physical frailty in women with normal age at natural menopause (after 45 years), while no elevated likelihood was observed in women with early natural menopause taking MHT. LIMITATIONS REASONS FOR CAUTION: The reproductive factors were self-reported and the data might be subject to recall bias. We lacked information on the types and initiation time of MHT, could not identify infertile women who later became pregnant, and the number of infertile women may be underestimated. Individuals participating in the UK Biobank are not representative of the general UK population, limiting the generalization of our findings. WIDER IMPLICATION OF THE FINDINGS: The reproductive factors experienced by women throughout their life course can potentially predict frailty in middle and old age. Identifying these reproductive factors as potential predictors of frailty can inform healthcare providers and policymakers about the importance of considering a woman's reproductive history when assessing their risk for frailty.

RESUMEN
Background: We estimated the health gains and health inequality impacts for the Australian population alive in 2021 (n = 25.0 million) in the next 20 years and over their remaining lifespan, from shifting everyone above a BMI of 25 kg/m2 to 25 kg/m2 compared to the BMI distribution in 2021 persisting into the future. Methods: National Health Survey 2017-2018 was used to estimate BMI distributions by sex, age and, socio-economic status (Socio-Economic Indexes for Areas; SEIFA). A proportional multistate life table linking BMI to 19 associated diseases and allowing for time lags and competing morbidity and mortality, was used to estimate the future stream of health adjusted life years (HALYs) gained from eradicating high BMI. Findings: Undiscounted health gains in the first 20 years and lifetime of the population were, respectively, 2.00 million (95% uncertainty interval 1.70-2.32) and 20.4 million (17.0-24.2) (at a 3% annual discount rate, HALY gains were 1.37 and 5.77 million, respectively). Reductions in the incidence of cardio metabolic diseases contributed 61% (95% UI: 54%-68%) of the undiscounted health gains in the first 20 years, musculoskeletal diseases contributed 26% (20%-32%) and cancer 5% (3%-8%). HALY gains in the first 20 years and lifetime, per person alive in 2021, were 2.5 (2.4-2.5) and 1.9 (1.9-2.0) times higher for the most compared to the least deprived SEIFA quintile. Interpretation: The total theoretical envelope of health gains, and health inequality reductions, through eradication of BMI is substantial. Our modeling infrastructure can be used to estimate the health impacts and cost effectiveness of many actual interventions. Funding: No funding was received for the study.
RESUMEN
Background: Whether the relationships between ABO blood genotypes (AA, AO, BB, BO, AB, and OO) and dementia are modified by gender and APOE status has been unclear. Methods: We used data from the UK Biobank, a population-based cohort study of 487,425 individuals. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CI) between ABO genotypes and risk of dementia. Multivariable linear regression models were used to estimate the relationship between ABO genotypes and MRI-based brain indices. Results: Overall, 487,425 participants were included at baseline. After 34 million person-years follow up, 7,548 patients developed all-cause dementia. Before stratifying by sex and APOE status, compared to OO genotype, BB genotype was associated with increased risk of all-cause dementia (1.36, 1.03-1.80) and other types dementia (1.65, 1.20-2.28). After stratifying by sex, only in males, BB genotype was associated with higher risk of all-cause dementia (1.44, 1.02-2.09) and other types of dementia (1.95, 1.30-2.93). AB genotype in males was also associated with increased AD (1.34, 1.04-1.72). After further stratifying by APOE e4 status, BB genotype with two APOE e4 alleles showed even stronger association with all-cause dementia 4.29 (1.57, 11.72) and other types dementia (5.49, 1.70-17.69) in males. Also in males, AA genotype with one APOE e4 was associated with increased risks of all-cause dementia (1.27, 1.04-1.55), AD (1.45, 1.09-1.94) and other types dementia (1.40, 1.08-1.81). Linear regression models showed that in both sexes with APOE e4, AA genotype was associated with reduced total grey matter volume. Conclusion: Sex and APOE e4 carrier status modified the association between ABO genotypes and risk of dementia. In males, BB genotype was consistently associated with increased risk of dementia, especially in those with two APOE e4 alleles. Also, in males with one APOE e4, AA genotype might be linked to higher risk of dementia.
RESUMEN
This study examined the association between salt-related knowledge, attitudes, and behaviors (KAB) and salt excretion using the 24-hour (24 h) urinary collection method. Data were utilized from the Community-Based Management of Non-Communicable Diseases in Nepal (COBIN) Salt Survey, a community-based cross-sectional study conducted among a sub-sample of COBIN cohort in Pokhara Metropolitan City, Western Nepal, from July to December 2018, among adults aged 25-70 years. A total of 451 adults participated in the study, and a single 24 h urine sample was collected from each participant. The mean [(standard deviation (SD)] age of the participants was 49.6 (9.82) years, and the majority were female (65%). The mean urinary salt excretion was 13.28 (SD: 4.72) g/day, with 98% of participants consuming ≥5 g of salt/day. Although 83% of participants knew the risks of high salt intake and 87% believed it was important to reduce their intake, only 10% reported doing so. Salt-related attitude i.e., self-perceived salt intake was significantly associated with urinary salt excretion, adding extra salt to food, consuming processed foods, and taking actions to salt control. Participants who perceived themselves as consuming high salt had higher urinary salt excretion [(14.42 g/day; 95% confidence interval (95% CI): 13.45, 15.39, p = 0.03)], were more likely to add extra [(Odds ratio (OR) = 3.59; 95% CI: 2.03, 6.33, p < 0.001)], and consume processed foods more often (OR = 1.90; 95% CI: 1.06, 3.40, p < 0.05) compared to those who self-perceived consuming a normal amount of salt. Conversely, participants who perceived themselves as consuming low salt were more likely to take actions to control salt intake (OR = 4.22; 95% CI: 1.90, 9.37, p < 0.001) compared to their counterparts who perceived consuming a normal amount of salt. There existed a gap between salt-related knowledge, attitudes, and actual behaviors, resulting in a high salt intake among the Nepalese population. Nepal urgently requires tailored national salt reduction programs that comprise both policy and community-level interventions to achieve a 30% reduction in mean population salt intake by 2025. Further validation studies are needed to assess the effectiveness of community-based intervention in Nepal.

Globally, demands for the kidneys have surpassed supply both living and deceased donors. High demands relative to the availability have made the kidney one of the most saleable human organs. The main objective was to explore the drivers of kidney selling. Literature related to kidney selling and its drivers was explored in three databases including MEDLINE (PubMed), Scopus (Elsevier), and JSTOR covering the period from 1987 to 2022. A total of 15 articles were selected, which underwent thematic analysis. Investigators independently assessed the articles for relevance and study quality to synthesize the data. The thematic analysis involved a critical approach to understanding the reasons for kidney selling by examining power disparities and social inequities. Kidney selling and the underlying reasons for it showed similarities across various geographic regions. Several factors were identified which increased individuals' vulnerability for kidney selling. At the micro level, poverty and illiteracy emerged as significant factors. Lack of financial safety nets obliged family to resort to kidney selling which helped to alleviate poverty, resolve debt, and other urgent financial issues. Nonetheless, the revenues from kidney selling were also used to purchase luxury items (diverting away from investing in livelihood expenses) such as buying motorbikes, mobile phones and televisions. Family, and gender responsibilities also played roles in kidney selling such as obligations related to paying dowry made parents particularly vulnerable. Surprisingly, a few victims of kidney selling later adopted kidney brokering role to support their livelihood. Kidney selling was further fostered by lack of stringent policy to regulate and monitor background checks for kidney transplantation. There were myriad factors that affected individual's vulnerability to kidney selling which stemmed from micro (poverty, illiteracy), meso (weak legal system, lacking stringent institutional policy, regulatory framework) and macro (social inequalities, corruption, organ shortage, insufficient health infrastructure) levels.
RESUMEN
BACKGROUND: The prevalence of low birth weight (LBW) has remained high (24.9%) in the South Asian region with a significant impact on newborn survival. This region bears nearly 40% of global burden of LBW. While antenatal care (ANC) and iron-folic acid supplementation independently have been considered effective for improving maternal and newborn outcomes, the evidence on the combined effect of these two supplements on LBW is lacking. This study aimed to examine the synergistic association of ANC and iron-folic acid supplementation on LBW in the South Asian region using pooled data from six South Asian countries. METHODS: Nationally representative surveys from Nepal, India, Bangladesh, Pakistan, Maldives, and Afghanistan were included in the study. Birth weight and the prevalence of LBW for singleton last-born children were reported using descriptive statistics. The association between LBW and ANC visits and the interaction between iron-folic acid consumption and ANC were examined using multiple logistic regression. RESULTS: The mean birth weight in the region was 2841.8 g with an LBW prevalence of 17.1%. Country-specific prevalence ranged from 11.4% in Nepal to 22.4% in Pakistan. Not attending ANC visits (adjusted odds ratio (AOR): 1.24; 95% confidence interval (CI): 1.16, 1.34) and not consuming iron-folic acid (AOR: 1.14; 95% CI: 1.08, 1.21) were significantly associated with a higher likelihood of LBW. Furthermore, jointly, having < 4 ANC visits and < 180 days of iron-folic acid supplementation was associated with a higher likelihood (AOR: 1.29; 95% CI: 1.22, 1.36) of having LBW compared to those who had ≥ 4 ANC visits and ≥ 180 days of iron-folic acid consumption after controlling for key confounding factors. CONCLUSIONS: The current study provides important evidence on the synergy between ANC visits and iron-folic acid consumption during pregnancy to capitalize on the existing national maternal health programs in the South Asian region, including low-and middle-income countries for positive foetal outcomes.

BACKGROUND: Cold indoor temperature (<18 °C) is associated with hypertension-related and respiratory disease, depression, and anxiety. We estimate total health, health expenditure and income impacts of permanently lifting the temperature in living areas of the home to 18 °C in cold homes in South-eastern Australia (N = 17 million). METHODS: A proportional multistate lifetable model was used to estimate health adjusted life years (HALYs), health expenditure and income earnings, over the remainder of the lifespan of the population alive in 2021 (3% discount rate). Multiple data were integrated including the prevalence of cold housing (5.87%; mean temperature 15 °C), the effect of temperature to hypertension-related, respiratory disease, depression and anxiety. FINDINGS: Eradicating cold housing was predicted to lead to 89,600 (95% UI 47,700 to 177,000) lifetime HALYs gained over the population's remaining lifespan, nearly half of which occurred from 2021 to 2040. Respiratory disease (32.4%) and mental illness (60.6%) made large contributions to HALYs gained, but also had large uncertainty (95% UI 30.0%-42.9% and 45.1%-64.6%, respectively) due to uncertain estimates of their magnitude of causal association with cold housing. Health gains per capita were 6.1 times greater (95% UI 4.7 to 8.1) among the most compared to least deprived quintile. From 2021 to 2040, health expenditure decreased by AUD$0.87 billion (0.35-1.98) and income earnings increased by AUD$4.35 billion (1.89-9.81). INTERPRETATION: Eliminating cold housing would lead to substantial health gains, reductions in health inequalities, savings in health expenditure, and productivity gains. Next steps require research to reduce uncertainty about the magnitude of causal associations of cold with mental and respiratory health.

BACKGROUND: Antenatal care (ANC) ensures continuity of care in maternal and foetal health. Understanding the quality and timing of antenatal care (ANC) is important to further progress maternal health in Nepal. This study aimed to investigate the proportion of and factors associated with, key ANC services in western Nepal. METHODS: Data from a community-based cohort study were utilized to evaluate the major ANC service outcomes: (i) three or less ANC visits (underutilization) (ii) late initiation (≥ 4 months) and (iii) suboptimal ANC (< 8 quality indicators). Mothers were recruited and interviewed within 30 days of childbirth. The outcomes and the factors associated with them were reported using frequency distribution and multiple logistic regressions, respectively. RESULTS: Only 7.5% of 735 mothers reported not attending any ANC visits. While only a quarter (23.77%) of mothers reported under-utilizing ANC, more than half of the women (55.21%) initiated ANC visits late, and one-third (33.8%) received suboptimal ANC quality. A total of seven factors were associated with the suboptimal ANC. Mothers with lower education attainment, residing in rural areas, and those who received service at home, were more likely to attain three or less ANC visits, late initiation of ANC, and report receiving suboptimal ANC. Furthermore, mothers from poor family backgrounds appeared to initiate ANC late. Mothers from disadvantaged Madhesi communities tended to receive suboptimal ANC. CONCLUSIONS: Despite a high ANC attendance, a significant proportion of mothers had initiated ANC late and received suboptimal care. There is a need to tailor ANC services to better support women from Madhesi ethnic community, as well as those with poor and less educated backgrounds to reduce the inequalities in maternal health care.

Objectives: To summarize the evidence on the association between sleep problems and multimorbidity. Methods: Six electronic databases (PubMed, Web of Science, Embase, China National Knowledge Infrastructure, VIP, and Wan fang) were searched to identify observational studies on the association between sleep problems and multimorbidity. A random-effects model was used to estimate the pooled odds ratios (ORs) and 95% confidence intervals for multimorbidity. Results: A total of 17 observational studies of 133,575 participants were included. Sleep problems included abnormal sleep duration, insomnia, snoring, poor sleep quality, obstructive sleep apnea (OSA) and restless legs syndrome (RLS). The pooled ORs (95% CIs) for multimorbidity were 1.49 (1.24-1.80) of short sleep duration, 1.21 (1.11-1.44) of long sleep duration and 2.53 (1.85-3.46) for insomnia. The association of other sleep problems with multimorbidity was narratively summarized due to limited number of comparable studies. Conclusion: Abnormal sleep duration and insomnia are associated with higher odds of multimorbidity, while the evidence on association of snoring, poor sleep quality, obstructive sleep apnea and restless legs syndrome with multimorbidity remains inconclusive. Interventions targeting sleep problems should be delivered for better management of multimorbidity.
RESUMEN
BACKGROUND: The sustainability and scalability of limited-duration interventions in low-income and middle-income countries remain unclear. We aimed to investigate the sustainability in reduction of blood pressure through a 12-month lifestyle intervention led by community health workers to reduce blood pressure in Nepal, 4 years after the intervention ceased. METHODS: The Community-Based Intervention for Control of Hypertension in Nepal (COBIN) trial was a non-blinded, cluster-randomised trial done in Kaski, Nepal. Adults aged 25-65 years were eligible. People were excluded if they declined consent, were severely ill, unlikely to be in the community throughout the intervention, or pregnant. During the 12-month intervention, female community health volunteers (FCHVs) visited participants in the intervention groups and provided lifestyle counselling and blood pressure measurement every 4 months. At the end of the 12-month intervention, systolic blood pressure was significantly lower in the intervention group than in the usual care group in all cohorts, ranging from -2·3 mm Hg (95% CI -3·8 to -0·8) lower in those with normal blood pressure to -4·9 mm Hg (-7·8 to -2·0) in the hypertensive cohort. The primary outcome for this follow-up study was a mean change in systolic blood pressure from baseline to follow-up at 60 months. We did an intention-to-treat analysis. FINDINGS: Between April 1, 2015, and Dec 31, 2015, 1638 participants were recruited in COBIN (939 [57·3%] assigned to intervention and 699 [42·7%] assigned to usual care). Of the 1468 (89·6%) who completed the 12-month assessments, we followed up 1352 (92·1%) participants at 60 months, between Oct 11, 2020, and May 5, 2022. 964 (71·3%) participants were women and 388 (28·7%) were men. From baseline to 60 months, the mean systolic blood pressure increased by 10·4 mm Hg (95% CI 9·1-11·6) in the intervention group and 6·0 mm Hg (4·6-7·5) in the usual care group (adjusted mean difference 4·1 mm Hg [2·2 to 5·8]). INTERPRETATION: Lifestyle counselling and blood pressure monitoring by community health workers is effective in substantially reducing blood pressure while adults are being monitored in a trial but, following cessation of the intervention, this benefit is not maintained in the long term, with potential for harm. This finding could have important implications for funders and research communities to regularly target participants for education and follow-up at an optimal timepoint to reduce any likelihood of harm.

BACKGROUND: Dementia and hearing loss are both highly prevalent conditions among older adults. We aimed to examine the association between hearing aid use and risk of all-cause and cause-specific dementia among middle-aged and older-aged adults, and to explore the roles of mediators and moderators in their association. METHODS: We used data from the UK Biobank, a population-based cohort study, which recruited adults aged 40-69 years between 2006 and 2010 across 22 centres in England, Scotland, and Wales. We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% CIs between self-reported hearing aid use status (hearing loss with or without hearing aids) at baseline and risk of dementia (all-cause dementia, Alzheimer's disease, vascular dementia, and non-Alzheimer's disease non-vascular dementia). Dementia diagnoses were ascertained using hospital records and death-register data. We also analysed the roles of mediators (self-reported social isolation, loneliness, and mood) and moderators (self-reported education and income, smoking, morbidity, and measured APOE allele status). FINDINGS: After the exclusion of people who did not answer the question on hearing difficulties (n=25 081 [5·0%]) and those with dementia at baseline visit (n=283 [0·1%]), we included 437 704 people in the analyses. Compared with participants without hearing loss, people with hearing loss without hearing aids had an increased risk of all-cause dementia (HR 1·42 [95% CI 1·29-1·56]); we found no increased risk in people with hearing loss with hearing aids (1·04 [0·98-1·10]). The positive association of hearing aid use was observed in all-cause dementia and cause-specific dementia subtypes (Alzheimer's disease, vascular dementia, and non-Alzheimer's disease non-vascular dementia). The attributable risk proportion of dementia for hearing loss was estimated to be 29·6%. Of the total association between hearing aid use and all-cause dementia, 1·5% was mediated by reducing social isolation, 2·3% by reducing loneliness, and 7·1% by reducing depressed mood. INTERPRETATION: In people with hearing loss, hearing aid use is associated with a risk of dementia of a similar level to that of people without hearing loss. With the postulation that up to 8% of dementia cases could be prevented with proper hearing loss management, our findings highlight the urgent need to take measures to address hearing loss to improve cognitive decline.

Objectives: The association between birth-related factors and dementia is unclear. We aimed to investigate their association and subsequent risk of dementia in a large-scale follow-up prospective study. Materials and Methods: This population-based cohort study used data from U.K. Biobank (2006-2010), and the median follow-up was 12.0 years. Multivariable-adjusted Cox proportional hazard models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) between number of children, age of first live birth, age of last live birth, span of births, and dementia. Restricted cubic spline models were used to quantify dose-response relationships. Results: A total of 253,611 women with mean age (standard deviation) of 56.3 (8.0) years were included. Compared with women with no child, women who had three or more children and first birth at age before 25 years, had elevated risk of all-cause dementia (HR: 1.30, 95% CI: 1.10-1.54), Alzheimer's disease (AD; 1.21, 1.00-1.46), and vascular dementia (VD; 1.59, 1.19-2.13). Also, women with three or more children and the last birth at age before 30 years, had increased risk of all-cause dementia (1.33, 1.11-1.59), AD (1.27, 1.03-1.57), and VD (1.55, 1.12-2.13). Moreover, women who had three or more children in <7 years, had an increased risk of all-cause dementia (1.25, 1.04-1.49). Dose-response relationship showed a lowest risk of dementia at having two children, and having three or more children in 7-9 years. Conclusions: Number of children, age of births, and span of births were all related to risk of dementia. These findings may help developing fertility policies or dementia prevention programs.

BACKGROUND: The Aotearoa/New Zealand Government is aiming to end the tobacco epidemic and markedly reduce Maori:non-Maori health inequalities by legislating: (1) denicotinisation of retail tobacco, (2) 95% reduction in retail outlets and (c) a tobacco free-generation whereby people born after 2005 are unable to legally purchase tobacco. This paper estimates future smoking prevalence, mortality inequality and health-adjusted life year (HALY) impacts of these strategies. METHODS: We used a Markov model to estimate future yearly smoking and vaping prevalence, linked to a proportional multistate life table model to estimate future mortality and HALYs. RESULTS: The combined package of strategies (plus media promotion) reduced adult smoking prevalence from 31.8% in 2022 to 7.3% in 2025 for Maori, and 11.8% to 2.7% for non-Maori. The 5% smoking prevalence target was forecast to be achieved in 2026 and 2027 for Maori males and females, respectively.The HALY gains for the combined package over the population's remaining lifespan were estimated to be 594 000 (95% uncertainty interval (UI): 443 000 to 738 000; 3% discount rate). Denicotinisation alone achieved 97% of these HALYs, the retail strategy 19% and tobacco-free generation 12%.By 2040, the combined package was forcat to reduce the gap in Maori:non-Maori all-cause mortality rates for people 45+ years old by 22.9% (95% UI: 19.9% to 26.2%) for females and 9.6% (8.4% to 11.0%) for males. CONCLUSION: A tobacco endgame strategy, especially denicotinisation, could deliver large health benefits and dramatically reduce health inequities between Maori and non-Maori in Aotearoa/New Zealand.
RESUMEN
BACKGROUND: Although diet has been extensively studied in relation to individual chronic conditions, studies linking diet with multiple chronic conditions (multimorbidity) remained scarce. We aimed to undertake a comprehensive analysis evaluating associations of overall dietary patterns and specific food groups with long-term risk of multimorbidity. METHODS: The study included 348,290 participants from UK Biobank who completed eligible food frequency questionnaires (FFQ) and were not diagnosed with any of the 38 chronic or mental health conditions of interest at baseline (2006-2010). Dietary patterns were identified using exploratory factor analysis. Cox regression models were used to estimate corresponding hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: The median follow-up was 8.01 years, and 50,837 (14.60%) participants developed multimorbidity. Among the three identified dietary patterns, the Western Pattern was associated with an increased risk of multimorbidity (HRQ5 vs Q1 = 1.06, 95% CI: 1.03-1.09), while inverse associations were observed for moderate adherence to the White Meat Pattern (HRQ3vs Q1 = 0.97, 95% CI: 0.94-0.99) and highest adherence to the Prudent Pattern (HRQ5 vs Q1 = 0.92, 95% CI: 0.90-0.95). For specific food groups, more frequent intakes of processed meat and poultry were associated with higher risks of multimorbidity, whereas higher intake frequency of fish and more intakes of fruits and cereal were associated with decreased risks. CONCLUSION: Dietary patterns and specific food groups are associated with the risk of multimorbidity. These findings suggest the importance of considering dietary interventions in the prevention and management of multimorbidity.

BACKGROUND: Behavioural risk factors of non-communicable diseases (NCDs) are socially patterned. However, the direction and the extent to which socioeconomic status (SES) influences behaviour changes before and after the diagnosis of NCDs is not clearly understood. We aimed to investigate the influence of SES on behaviour changes (physical inactivity and smoking) before and after the diagnosis of major NCDs. METHODS: In this multicohort study, we pooled individual-level data from six prospective cohort studies across 17 countries. We included participants who were diagnosed with either diabetes, cardiovascular disease, chronic lung disease, or cancer after recruitment. Participants were surveyed every 2 years. Education and total household wealth were used to construct SES. We measured behaviour changes as whether or not participants continued or initiated physical inactivity or smoking after NCD diagnosis. We used multivariable logistic regression models to estimate odds ratios (ORs), prevalence ratios (PRs), and 95% CIs for the associations between SES and continuation or initiation of unfavourable behaviours. FINDINGS: We included 8107 individuals recruited between March, 2002, and January, 2016. Over the 4-year period before and after NCD diagnosis, 886 (60·4%) of 1466 individuals continued physical inactivity and 1018 (68·8%) of 1480 participants continued smoking; 1047 (15·8%) of 6641 participants with physical activity before diagnosis initiated physical inactivity after diagnosis and 132 (2·0%) of 6627 non-smokers before diagnosis initiated smoking after diagnosis. Compared with participants with high SES, those with low SES were more likely to continue physical inactivity (244 [70·3%] of 347 vs 23 [50.0%] of 46; PR 1·41 [95% CI 1·05-1·99]; OR 2·28 [1·18-4·41]), continue smoking (214 [75·4%] of 284 vs 39 [60·9%] of 64; PR 1·27 [1·03-1·59]; OR 2·08 [1·14-3·80]), but also to initiate physical inactivity (188 [26·1%] of 720 vs 47 [7·4%] of 639; PR 3·59 [2·58-4·85]; OR 4·31 [3·02 - 6·14]). INTERPRETATION: Low SES was associated with continuing or initiating physical inactivity and continuing smoking after NCD diagnosis. Reducing socioeconomic inequality in health behaviour changes should be prioritised and integrated into NCD-prevention programmes.

Recent crises have underscored the importance that housing has in sustaining good health and, equally, its potential to harm health. Considering this and building on Howden-Chapman's early glossary of housing and health and the WHO Housing and Health Guidelines, this paper introduces a range of housing and health-related terms, reflecting almost 20 years of development in the field. It defines key concepts currently used in research, policy and practice to describe housing in relation to health and health inequalities. Definitions are organised by three overarching aspects of housing: affordability (including housing affordability stress (HAS) and fuel poverty), suitability (including condition, accessibility and sustainable housing) and security (including precarious housing and homelessness). Each of these inter-related aspects of housing can be either protective of, or detrimental to, health. This glossary broadens our understanding of the relationship between housing and health to further promote interdisciplinarity and strengthen the nexus between these fields.

BACKGROUND: Whether the association of cardiovascular diseases (CVDs) with dementia differs by sex remains unclear, and the role of socioeconomic, lifestyle, genetic, and medical factors in their association is unknown. METHODS: We used data from the UK Biobank, a population-based cohort study of 502,649 individuals. We used Cox proportional hazards models to estimate sex-specific hazard ratios (HRs) and 95% confidence intervals (CI), and women-to-men ratio of HRs (RHR) for the association between CVD (coronary heart diseases (CHD), stroke, and heart failure) and incident dementia (all-cause dementia, Alzheimer's Disease (AD), and vascular dementia (VD)). The moderator roles of socioeconomic (education, income), lifestyle (smoking, BMI, leisure activities, and physical activity), genetic factors (APOE allele status), and medical history were also analyzed. RESULTS: Compared to people who did not experience a CVD event, the HRs (95%CI) between CVD and all-cause dementia were higher in women compared to men, with an RHR (Female/Male) of 1.20 (1.13, 1.28). Specifically, the HRs for AD were higher in women with CHD and heart failure compared to men, with an RHR (95%CI) of 1.63 (1.39, 1.91) and 1.32 (1.07, 1.62) respectively. The HRs for VD were higher in men with heart failure than women, with RHR (95%CI) of 0.73 (0.57, 0.93). An interaction effect was observed between socioeconomic, lifestyle, genetic factors, and medical history in the sex-specific association between CVD and dementia. CONCLUSION: Women with CVD were 1.5 times more likely to experience AD than men, while had 15% lower risk of having VD than men.
