Objective: To investigate whether marijuana use is associated with involuntary job loss Methods: Multivariable survey logistic analysis of longitudinal (2001–2002/2003–2004) and cross-sectional data (2012–2013) from National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Results: Marijuana use increased for all user groups with most workers who use marijuana using marijuana monthly (2.7% in 2001–2002 and10.8% in 2012–2013). Past year marijuana users in 2001–2002 had higher odds of involuntary job loss in 2003–2004 (OR 1.27; 95%CI 1.13–1.41). Daily marijuana use is associated with higher odds of job loss in adjusted analyses using longitudinal (OR 2.18; 95%CI 1.71–2.77) and cross-sectional data (OR 1.40; 95%CI 1.06–1.86). Income significantly modifies these effects. Conclusions: Findings indicate that job loss may be an overlooked social cost of marijuana use for US workers. Future studies using an occupational health perspective are needed.
ImportanceHigher educational attainment is associated with reduced dementia risk, but the role of educational quality is understudied, presenting a major evidence gap, especially as it may contribute to racial inequities.ObjectiveTo evaluate the association between state-level educational quality during childhood and dementia risk.Design, Setting, and ParticipantsThis cohort study analyzed longitudinal data collected from January 1, 1997, through December 31, 2019 (23-year follow-up period). The sample comprised members of Kaiser Permanente Northern California (KPNC), a large integrated health care delivery system, who completed an optional survey during 1964-1972. Eligible individuals were US born; non-Hispanic Black or non-Hispanic White; aged 65 years or older as of January 1, 1996; were still alive; and did not have a dementia diagnosis or lapse in KPNC membership greater than 90 days between January 1 and December 31, 1996.ExposuresHistorical state-level administrative indicators of school quality (school term length, student-teacher ratio, and attendance rates) linked to participants using birth state and birth year (with a 6-year lag) and divided into tertiles using the pooled sample.Main Outcomes and MeasuresDementia diagnoses from electronic health records between 1997 and 2019 were analyzed between March 1 and August 31, 2022. The associations of educational quality with incident dementia were estimated using Cox proportional hazards regression models.ResultsAmong 21 450 KPNC members who participated in the optional survey, individuals born before availability of educational quality records (n = 87) and missing educational attainment (n = 585) were excluded. The final analytic sample was 20 778 individuals (56.5% women, 43.5% men; mean [SD] age, 74.7 [6.5] years; 18.8% Black; 81.2% White; 41.0% with less than high school education). Among Black individuals, 76.2% to 86.1% (vs 20.8%-23.3% of White individuals) attended schools in states in the lowest educational quality tertiles. Highest (vs lowest) educational quality tertiles were associated with lower dementia risk (student-teacher ratio: hazard ratio [HR], 0.88 [95% CI, 0.83-0.94]; attendance rates: HR, 0.80 [95% CI, 0.73-0.88]; term length: HR, 0.79 [95% CI, 0.73-0.86]). Effect estimates did not differ by race and were not attenuated by adjustment for educational attainment.Conclusions and RelevanceIn this cohort study, lower state-average educational quality was more common among Black individuals and associated with higher dementia risk. Differential investment in high-quality education due to structural racism may contribute to dementia disparities.
This article discusses the impacts of midlife social exposures on health in later life, especially for women. Of particular interest is the period of early adulthood. Social epidemiology and life course frameworks help reveal how workplace exposures, family dynamics, and public policies related to work and family shape opportunities in midlife that have long-run health consequences. This is especially important for American women, who have experienced health disadvantages over the last decades compared to women in similarly advanced industrialized countries. In most countries, single women are especially at high risk for poor health at older ages, and job strain can elevate future risks particularly for this subpopulation. Public policies such as maternity leave can reduce risks for poor mental health outcomes among working mothers 30 to 40 years after childbirth, suggesting that the period of early and middle adulthood may influence health trajectories well into old age.
Background: Evidence suggests a link between depressive symptoms and risk of subsequent stroke. However, most studies assess depressive symptoms at only one timepoint, with few examining this relationship using repeatedly measured depressive symptoms. This study aimed to examine the relationship between depressive symptom trajectories and risk of incident stroke. Methods: This prospective cohort included 12 520 US individuals aged ≥50 years enrolled in the Health and Retirement Study, free of stroke at study baseline (1998). We used the 8-item Center for Epidemiologic Studies Depression scale to assess depressive symptoms (high defined as ≥3 symptoms; low <3 symptoms) at 4 consecutive, biennial timepoints from 1998 to 2004. We assigned individuals to 5 predefined trajectories based on their scores at each timepoint (consistently low, decreasing, fluctuating, increasing, and consistently high). Using self-reported doctors’ diagnoses, we assessed incident stroke over a subsequent 10-year period from 2006 to 2016. Cox regression models estimated the association of depressive symptom trajectories with risk of incident stroke, adjusting for demographics, health behaviors, and health conditions. Results: During follow-up, 1434 incident strokes occurred. Compared with individuals with consistently low symptoms, individuals with consistently high depressive symptoms (adjusted hazard ratio, 1.18 [95% CI, 1.02–1.36]), increasing symptoms (adjusted hazard ratio, 1.31 [95% CI, 1.10–1.57]), and fluctuating symptoms (adjusted hazard ratio, 1.21 [95% CI, 1.01–1.46]) all had higher hazards of stroke onset. Individuals in the decreasing symptom trajectory group did not show increased stroke risk. Conclusions: Depressive symptom trajectories characterized by high symptoms at multiple timepoints were associated with increased stroke risk. However, a trajectory with depressive symptoms that started high but decreased over time was not associated with higher stroke risk. Given the remitting-relapsing nature of depressive symptoms, it is important to understand the relationship between depressive symptoms and stroke risk over time through repeated assessments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
