Prevalence and correlates of substance use disorders among older adolescents in Puerto Rico and the United States: a cross-cultural comparison.
Although there are substantial data on adolescent substance use, little systematic research has studied the prevalence of adolescent substance disorders in general populations, let alone cultural differences in disorder prevalence. In this paper we report the prevalence and correlates of alcohol and drug use and disorder among older adolescents on Puerto Rico (PR) and in the United States (US). Data come from an island-wide survey of the PR general residential population (15-18 year old subsample, unweighted N=922) fielded in 1997, and from the National Comorbidity Survey of the US household population (15-18 year old subsample, unweighted N=641), fielded in 1991. Both surveys used a similar standardized interview based on the Composite International Diagnostic Interview (CIDI) to generate DSM-IV diagnoses. Bivariate analyses and logistic regression were used. The major findings are: (1) US youth report higher rates of lifetime alcohol and drug use and substance-related disorder than PR youth; (2) the transition to abuse or dependence occurs for one-third of US drinkers, one-fifth of drinkers in PR, and about one-half of the drug users in both US and PR; (3) there are marked variations across sites in the types of symptoms substance users are likely to experience; (4) with the exception of family income, most correlates operate similarly in both sub-samples; and (5) the majority of both US and PR youth with a past year substance use disorder did not report any service utilization in the past year.
