BackgroundThis study aimed to investigate the impact of tobacco industry interference on the implementation and management of tobacco control and the tobacco epidemic using the Tobacco Industry Interference Index (TIII) and MPOWER—a package of measures for tobacco control—and adult daily smoking prevalence in 30 countries.MethodsThe TIII was extracted from the Global Tobacco Industry Interference Index 2019 and Global Center for Good Governance in Tobacco Control (GGTC). MPOWER measures and adult daily smoking prevalence rate were extracted from the World Health Organization (WHO) report on the global tobacco epidemic in 2021. We assessed the ecological cross-lagged association between TIII and MPOWER scores and between TIII and age-standardized prevalence rates for adult daily tobacco users.ResultsTobacco industry interference was inversely correlated with a country’s …

ObjectivesThe sense of coherence refers to effectively using available resources to manage stress and promote overall health. Previous studies have linked it to various health outcomes; however, evidence regarding its association with the risk of incident dementia is limited. Hence, this study aimed to fill this research gap using data from a large-scale population survey.DesignProspective cohort study.Setting and ParticipantsThis study included 31,556 participants aged 65 years and older who were free from dementia and disabilities. The participants were enrolled in the 2010 baseline survey of the Japan Gerontological Evaluation Study, and were followed up until the end of 2019.MethodsThe sense of coherence was assessed using a 6-item short-version questionnaire. Incident dementia cases were ascertained through the public long-term care insurance database in Japan.ResultsDuring a median follow-up of …

Despite major strides in cancer research and therapy, these advances have not been equitable across race and ethnicity. Historically marginalized groups (HMG) are more likely to have inadequate preventive screening, increased delays in diagnosis, and poor representation in clinical trials. Notably, Black, Hispanic, and Indigenous people represent 30% of the population but only 9% of oncology clinical trial participants. As a result, HMGs lack equitable access to novel therapies, contradicting the principle of distributive justice, as enshrined in the Belmont report, which demands the equitable selection of subjects in research involving human subjects. The lack of clinical trial diversity also leads to low generalizability and potentially harmful medical practices. Specifically, patients with brain cancer face unique barriers to clinical trial enrollment and completion due to disease-specific neurologic and treatment …

BackgroundResearch on the health and economic costs due to insufficient sleep remains scant in developing countries. In this study we aimed to estimate the years of life lost (YLLs) due to short sleep and quantify its economic burden in China.MethodsWe estimated both individual and aggregate YLLs due to short sleep (ie,≤ 6 hours) among Chinese adults aged 20 years or older by sex and five-year age groups in 2010, 2014, and 2018. YLL estimates were derived from 1) the prevalence of short sleep using three survey waves of the China Family Panel Studies, 2) relative mortality risks from meta-analyses, and 3) life tables in China. YLL was the difference between the estimated life expectancy of an individual in the short sleep category vs in the recommended sleep category. We estimated the economic cost using the human capital approach.ResultsThe sample sizes of the three survey waves were 31 393, 31 …

Background We examined associations between dog ownership, morning dog walking and its timing and duration, and depression risk in female nurses, exploring effect modification by chronotype. We hypothesized that dog ownership and morning walking with the dog are associated with lower odds of depression, and that the latter is particularly beneficial for evening chronotypes by helping them to synchronize their biological clock with the solar system. Methods 26,169 depression-free US women aged 53–72 from the Nurses’ Health Study 2 (NHS2) were prospectively followed from 2017–2019. We used age- and multivariable-adjusted logistic regression models to estimate odds ratios (ORs) and 95% confidence intervals (95%CIs) for depression according to dog ownership, and morning dog walking, duration, and timing. Results Overall, there was no association between owning a dog (ORvs_no_pets = 1.12, 95%CI = 0.91–1.37), morning dog walking (ORvs_not = 0.87, 95%CI = 0.64–1.18), or the duration (OR>30min vs. ≤15mins = 0.68, 95%CI = 0.35–1.29) or timing of morning dog walks (ORafter9am vs. before7am = 1.06, 95%CI = 0.54–2.05) and depression. Chronotype of dog owners appeared to modify these associations. Compared to women of the same chronotype but without pets, dog owners with evening chronotypes had a significantly increased odds of depression (OR = 1.60, 95%CI = 1.12–2.29), whereas morning chronotypes did not (OR = 0.94, 95%CI = 0.71–1.23). Further, our data suggested that evening chronotypes benefited more from walking their dog themselves in the morning (OR = 0.75, 95%CI = 0.46–1.23, Pintx …

Background: The global increase of the incidence of early-onset cancers (defined as cancers diagnosed at 20-49 years) is a serious public health problem. However, it is understudied whether the incidence of early-onset cancers has increased in parallel with that of later-onset cancers (defined as cancers diagnosed at 50 years or above) or only the incidence of early-onset cancer has increased worldwide. We therefore evaluated the recent global trends of the incidence of early-onset cancers and later-onset cancers. Method: We retrieved sex-stratified age-standardized incidence rates of early-onset cancer and later-onset cancer diagnosed between 2000 and 2012 in 39 countries where data was available from the GLOBOCAN database. Using joinpoint regression models, we assessed average annual percentage change (AAPC) by cancer types and countries, with statistical significance corresponding to a 95 …

RationalePrevious research has shown that uncertainty can affect mental health, and that unemployment and economic recessions are associated with increased suicide rates.ObjectiveThe objective of this article was to examine whether daily fluctuations in economic uncertainty can result in short-term spikes in the number of suicides. While existing evidence has focused on medium- and long-term effects of economic conditions on suicide, this study examined immediate daily deviations from the background general trend.MethodsWe used daily suicide data from England and Wales that were matched to a daily economic policy uncertainty index over the period 2001–2015. We followed an econometric approach to examine the impact of uncertainty on suicides, controlling for unemployment rates.ResultsWe found that a spike in daily economic uncertainty leads to an immediate, yet short-lived, impact on suicides.

The COVID-19 pandemic has worsened health disparities worldwide. Across all nations, the burden of COVID-19 has fallen most heavily on the socially disadvantaged. In the United States, the COVID-19 mortality rate for Black Americans is over twice that of their White American counterparts, and people in prisons have more than double the COVID-19 mortality rate of the general US population. Other social dimensions such as income, gender, sexuality, and immigration status have also played a significant role in COVID-19 infection, hospitalization, and mortality. The Social Epidemiology of the COVID-19 Pandemic provides an interdisciplinary analysis of the pandemic's effect across populations and its disproportionate impact on vulnerable groups in society, including racial/ethnic minority, immigrant, and incarcerated populations. Written by leading international scholars, this essential volume describes how the COVID-19 pandemic intersects with nearly every social determinant of health, from race and ethnicity to income inequality, and how such interactions compound existing structural disadvantages. Using examples from upper-middle and high-income countries such as the United States, contributing experts delve into the differential impacts of COVID-19 by major social determinants of health and reveal the resultant effect of pandemic-related policy on health outcomes. Together, these authors underline the urgent need for further integration of social epidemiology into public health decision-making to ensure that every population receives the care it requires. Drawing from research across epidemiology, sociology, psychology, and public …
