Tobacco and Alcohol Use by Muslim Indonesian Adolescents: Longitudinal Associations With Religiosity and Problem Behavior.

Abstract

This three-wave (10th to 12th grade) longitudinal study explored the interrelations of religiosity, tobacco and alcohol use, and problem behavior in Indonesian Muslim adolescents. The sample included 721 Muslim Indonesian adolescents (48% girls) who participated in at least one assessment when they were in 10th, 11th, or 12th grade. Of these, 499 were recruited in 10th grade, with others added at 11th and 12th grades. Prior month use for 10th-grade boys and girls, respectively, was 49.2% and 5.2% for tobacco and 19.0% and 3.6% for alcohol. Tobacco use and alcohol use were negatively associated with religiosity for boys, but these associations were more inconsistent for girls. Consistent with U.S. findings, there was a bidirectional longitudinal association between tobacco and alcohol use. The longitudinal models and associations with problem behavior were similar for both sexes. These results provide evidence of negative longitudinal associations between religiosity and tobacco use. The more frequent use of tobacco than alcohol may be attributable to religion, cost differentials, and social norms. Despite large gender differences in the frequencies of use, the similar predictors of tobacco and alcohol use for boys and girls suggest that models accounting for substance use are comparable for both sexes. These results have implications for the design of prevention programs in Indonesia and other culturally and religiously similar countries.
