Background: Early alcohol use is hazardous to health and restrictions to age at first drink (AFD) is a cornerstone of public health policy in many nations. We explored the long-term impact of AFD on mortality after early adulthood in community-dwelling Koreans.
Methods: A cohort of 36 159 adults aged 35-64 years from the Korean National Health and Nutrition Examination Survey, linked to cause-of-death statistics, was followed up for a median of 9.9 years. Based on AFD with a cutoff at South Korea's legal drinking age, the participants were divided into three groups: AFD < 19, AFD ≥ 19, and lifetime abstainer. The outcome variable was all-cause mortality.
Results: A total of 9723 (26.9%) participants reported AFD < 19. During the follow-up, 1073 (3.0%) participants died. AFD < 19 was associated with an increased risk of mortality than lifetime abstainers (adjusted hazards ratio [aHR] 1.29, 95% confidence interval [CI] 1.02-1.64). Female drinkers with AFD < 19 showed an increased risk of mortality than female lifetime abstainers (aHR 2.02, CI 1.26-3.25). Current drinkers with AFD < 19 was associated with a greater risk of mortality than those with AFD ≥ 19 (aHR 1.20, 95%CI 1.01-1.42). Among participants with hazardous drinking habits, AFD < 19 was associated with a greater risk of mortality than AFD ≥ 19 (aHR 1.32, 95%CI 1.07-1.64).
Conclusion: Individuals with AFD < 19 were at greater risk of mortality than lifetime abstainers; earlier AFD was associated with a greater mortality risk than later AFD. Prevention and early intervention programs can improve the long-term health of alcohol-consuming population.

Introduction: Epidemiological studies focusing on the association of exposure to perfluoroalkyl substances (PFAS) with cardiovascular disease (CVD) morbidity and mortality are limited, with inconsistent findings.
Objectives: This register-based study aimed to investigate the associations between exposure to PFAS and the risk of CVD morbidity and mortality in a Swedish population exposed to PFAS, dominated by perfluorohexane sulfonic acid (PFHxS) and perfluorooctane sulfonic acid (PFOS), through drinking water for decades.
Methods: The study included 46 553 individuals aged ≥30 who lived in Ronneby (1985-2013).

Pedestrian injuries remain a public health concern, with child pedestrians being particularly vulnerable due to their unique physical and cognitive characteristics. This study presents a comprehensive analysis comparing injury severity patterns between child (≤14 years) and non-child (>14 years) pedestrians using Lasso logistic regression and advanced machine learning techniques, specifically Catboost with SHAP (SHapley Additive exPlanations) values to interpret the models. By analyzing six years of national crash data from the Crash Report Sampling System (CRSS) from 2016 to 2021, we identify significant factors influencing injury outcomes for both age groups.

Plantation forest areas are rapidly expanding worldwide. Forests at different stand ages exhibit distinct patterns in litterfall input, soil microbial diversity, and enzyme activity, all of which potentially affect the properties of dissolved organic matter (DOM). DOM is an important precursor of disinfection byproducts (DBPs).

Background: Prior longitudinal studies demonstrate that sleep disturbance is a risk factor for alcohol misuse. Experimental research also shows that alcohol intake negatively impacts sleep. The present study evaluated temporal bidirectional relationships between sleep and alcohol intake using intensive longitudinal methods.

Despite rising concerns about alcohol use in artisanal mining, a focused investigation into its psychosocial drivers and mental health implications within sub-Saharan Africa's informal mining sector remains scarce. This study investigates the prevalence, motivations, and the association between alcohol use and mental health outcomes (depression, anxiety, and stress) among artisanal miners in Ghana. Using community based cross-sectional survey data from 664 miners, alcohol use was assessed using the Alcohol Use Disorders Identification Test, while symptoms of anxiety, stress, and depression were measured via the GAD-7, PSS, and PHQ-9 instruments.
