Adolescents' expectations for the future predict health behaviors in early adulthood.

ABSTRACT: Health-related behaviors in adolescence establish trajectories of risk for obesity and chronic degenerative diseases, and they represent an important pathway through which socio-economic environments shape patterns of morbidity and mortality. Most behaviors that promote health involve making choices that may not pay off until the future, but the factors that predict an individual's investment in future health are not known. In this paper we consider whether expectations for the future in two domains relevant to adolescents in the U.S.-perceived chances of living to middle age and perceived chances of attending college-are associated with an individual's engagement in behaviors that protect health in the long run. We focus on adolescence as an important life stage during which habits formed may shape trajectories of disease risk later in life. We use data from a large, nationally representative sample of American youth (the US National Longitudinal Study of Adolescent Health) to predict levels of physical activity, fast food consumption, and cigarette smoking in young adulthood in relation to perceived life chances in adolescence, controlling for baseline health behaviors and a wide range of potentially confounding factors. We found that adolescents who rated their chances of attending college more highly exercised more frequently and smoked fewer cigarettes in young adulthood. Adolescents with higher expectations of living to age 35 smoked fewer cigarettes as young adults. Parental education was a significant predictor of perceived life chances, as well as health behaviors, but for each outcome the effects of perceived life chances were independent of, and often stronger than, parental education. Perceived life chances in adolescence may therefore play an important role in establishing individual trajectories of health, and in contributing to social gradients in population health.

Project description:ImportanceDeaths from self-injury are increasing. Understanding the sources of risk is important for prevention and treatment.ObjectiveTo estimate the risks of suicide and drug poisoning deaths among adult men whose adolescent occupational expectations were not met in adulthood.Design, setting, and participantsThis cohort study included a sample of men interviewed as part of the High School and Beyond study, a nationally representative study of US high school sophomores and seniors in 1980, who were interviewed every 2 years through 1986; those who were sophomores in 1980 were reinterviewed in 1992. Men who survived to 1992 and reported occupational expectations were included in the present study. Death records prior to 2018 were linked to mortality databases and released in 2019. Data analysis was conducted from May to October 2020.ExposureOccupational expectations.Main outcomes and measuresSurvival or death by suicide, drug poisoning, chronic liver disease, heart disease, cancer, or some other cause, categorized from International Classification of Diseases, Ninth Revision and Tenth Revision codes. Competing risk Fine-Gray survival models regressed cause of death on adolescent occupational expectations and covariates.ResultsThe 11 680 men in the High School and Beyond cohort study had a median (interquartile range) age of 29 (28-30) years in 1992, when the analysis of their future mortality began. Most men survived until 2015 (11 060 [weighted percentage, 95.0%]). Reported causes of death were suicide (60 [weighted percentage, 0.5%]), drug poisoning (40 [weighted percentage, 0.4%]), chronic liver disease (20 [weighted percentage, 0.2%]), heart disease (130 [weighted percentage, 1.0%]), cancer (100 [weighted percentage, 1.0%]), and other (280 [weighted percentage, 2.0%]). Subhazard ratios for death by suicide and drug poisoning were 2.91 (95% CI, 1.07-7.88; P = .04) and 2.62 (95% CI, 1.15-5.94; P = .02) times higher, respectively, among those who in 1980 expected to hold a subbaccalaureate occupation that later declined in labor market share compared with those with professional occupational expectations. The actual job held by men did not attenuate the hazards of deaths from suicide and drug poisoning.Conclusions and relevanceIn this cohort study, men whose occupational expectations were not met because of labor market declines were at a higher risk of death from suicide or drug poisoning than men with different occupational expectations. Interventions to mitigate labor market changes should account for individuals' expectational ideals.

Project description:OBJECTIVES:We sought to examine the association of early adulthood blood pressure with cardiovascular disease (CVD) mortality, while accounting for middle-age hypertension. BACKGROUND:Elevated blood pressure in middle age is an established CVD risk factor, but evidence for association with measurements earlier in life is sparse. METHODS:The HAHS (Harvard Alumni Health Study) is a cohort study of 18,881 male university students who had their blood pressure measured at university entry (1914 to 1952; mean age 18.3 years) and who responded to a questionnaire mailed in either 1962 or 1966 (mean age 45.8 years) in which physician-diagnosed hypertension status was reported. Study members were subsequently followed for mortality until the end of 1998. RESULTS:Following adjustment for age, body mass index, smoking, and physical activity at college entry, compared with men who were normotensive according to the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure criteria (<120/<80 mm Hg), there was an elevated risk of coronary heart disease (CHD) mortality (1,917 deaths) in those who were pre-hypertensive (120 to 139/80 to 89 mm Hg) (hazard ratio [HR]: 1.21; 95% confidence interval [CI]: 1.07 to 1.36), stage 1 (140 to 159/90 to 99 mm Hg) (HR: 1.46; 95% CI: 1.25 to 1.70), and stage 2 hypertensive (?160/?100 mm Hg) (HR: 1.89; 95% CI: 1.46 to 2.45), incremental across categories (p(trend) < 0.001). After additionally accounting for middle-age hypertension, estimates were somewhat attenuated, but the pattern remained. Similar associations were apparent for total and CVD mortality, but not stroke mortality. CONCLUSIONS:Higher blood pressure in early adulthood was associated with elevated risk of all-cause mortality, CVD, and CHD, but not stroke, several decades later. Effects largely persisted after taking into account mediation by middle-age hypertension. Thus, the long-term benefits of blood pressure lowering in early adulthood are promising, but supporting trial data are required.
