Researchers analyzed the first three waves of data collected during the National Longitudinal Study of Adolescent Health for 2,447 twin and sibling pairs (30% male pairs, 32% female pairs, 38% opposite sex pairs) ranging in age from 13 to 27 years. Wave 1 was collected from 1994 to 1995, Wave 2 from 1995 to 1996, and Wave 3 from 2001 to 2002.<\/p>\n Results supported previous findings showing that genetic and environmental influences on alcohol use change during adolescence and young adulthood<\/strong>. In addition to genetic and environmental influences that were common to these age groups, there were genetic and environmental influences that were important only during adolescence. Friends’ drinking behavior was a more pervasive influence on adolescents’ drinking than parenting practices<\/strong>. The authors suggested that interventions and prevention programs geared toward reducing alcohol use in younger populations could benefit from a focus on peer influence<\/strong>.<\/p>\n<\/div>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":" From the Research Society on Alcoholism press release: The etiology (i.e., underlying causes) of a behavior, such as alcohol drinking, can change during adolescence and young adulthood.

The etiology (i.e., underlying causes) of a behavior, such as alcohol drinking, can change during adolescence and young adulthood<\/strong>. Prior alcohol research has shown that, in general: shared\/common environment influences are strongest in early adolescence, declining in strength until young adulthood; unique environmental influences are moderate, but stable, during adolescence and young adulthood; and genetic influences are weakest during early adolescence, steadily increasing in strength until young adulthood. This study examined the relations between genetic and environmental etiologies of alcohol use<\/strong> and the influence of peer use, parental autonomy granting, and maternal closeness<\/strong> on this behavior.<\/p>\n
