Socio-demographic risk factors for alcohol and drug dependence: the 10-year follow-up of the national comorbidity survey.

Aims: Continued progress in etiological research and prevention science requires more precise information concerning the specific stages at which socio-demographic variables are implicated most strongly in transition from initial substance use to dependence. The present study examines prospective associations between socio-demographic variables and the subsequent onset of alcohol and drug dependence using data from the National Comorbidity Survey (NCS) and the NCS Follow-up survey (NCS-2).

Design: The NCS was a nationally representative survey of the prevalence and correlates of DSM-III-R mental and substance disorders in the United States carried out in 1990-2002.

Improving targets for the prevention of drug use disorders: sociodemographic predictors of transitions across drug use stages in the national comorbidity survey replication.

Objectives: Models of drug use etiology and prevention require precise information concerning the expression of population-based risk factors across the continuum of drug use. However, the majority of previous epidemiologic research on this topic has not addressed transitions between specific drug stages. The present investigation examined the sociodemographic predictors of progression across six stages of drug use in the National Comorbidity Survey Replication (NCS-R), a nationally representative household survey of the U.
