Researchers conducted a descriptive study using a convenience sample to determine rates of and risk factors for alcohol consumption among 470 girls enrolled in a girls-only high school in a high-risk district of Lima, Peru. A survey was distributed to the students and returned after parental consent and student assents were obtained. Results analyzed by chi square and logistic regression indicated that 5.96% of the students drank alcoholic beverages. Risk factors for drinking were self-described aggressiveness (6.6 times more likely to drink), unhappiness with behavior or family life (3.4 and 4.1), and attending parties (3.7). Protective factors that contributed to a 66-67% less likelihood of drinking were self-descriptions of being kind and responsible. Directions for future research and development of prevention programs are discussed.
