Teen Alcohol Misuse is a Driver of Poorer Health and Dissatisfaction in Midlife, according to a New Twin Study

Alcohol misuse in adolescence affects physical health and life satisfaction over multiple decades, outcomes that are driven by ongoing alcohol problems, a new study has found. The link between teen drinking and poor health into the 30s held even after accounting for the effects of nature (genes) and nurture (early family environments). Problematic drinking in adolescence is known to be linked to ongoing health and life struggles. Better understanding this process could inform early targeted interventions that may prevent or ameliorate long-term negative consequences. The new study, in Alcoholism: Clinical & Experimental Research, sought to clarify the pathways — direct or indirect — by which teen drinking has such far-reaching effects. Investigators explored participants’ alcohol misuse in adolescence and early adulthood, and physical health and life satisfaction in their mid-30s. The study sample was restricted to twins, allowing for consideration of shared genetic and environmental f
