E-Mail New research from the Prevention Research Center of the Pacific Institute for Research and Evaluation and the Illinois State University examines changes in adolescent drinking over the course of the evening and finds that: Drinking earlier in the evening is positively associated with continued drinking over the night course. Adolescents' drinking contexts change through the evening including: Situational factors, such as alcohol availability and adult supervision, social factors, such as the number of people and presence of friends, location factors, such as home settings Specific contextual characteristics shape drinking behavior at later times in the evening: Being at home earlier in the evening (5pm-8pm) was associated with lower odds of drinking in mid-evening (8pm to 11pm) and being at home in mid-evening increased alcohol use in the late evening (11pm+).
