Abstract

To examine the potential impact of prevalence of alcohol use in a birth-sex cohort on subsequent initiation and progression of alcohol use in the PEGASUS-Murcia project, a cross-sectional survey of a representative sample of non-institutionalized adults in Murcia (Spain). Data on lifetime history of alcohol use, DSM-IV use disorders, and remission were collected from 1,459 adults using face-to-face interviewers based on the Composite International Diagnostic Interview (CIDI 3.0). Life-table estimates based on survival functions for alcohol use age-of-onset and remission were used as time-varying predictors of subsequent individual-level alcohol use in discrete-time survival models. Nearly nine out of ten adults had a lifetime alcohol use history at time of interview. Of these lifetime users, 84.3% became regular users (>12 drinks a year) and 5.5-1.6% went on to meet criteria for DSM-IV alcohol abuse or dependence, respectively. By the age of 18, 70.9% of respondents had used alcohol, and one half (50.2%) had used regularly. Regular use sharply increased during early adulthood to reach 90.8% by age 22. Birth-sex cohort alcohol use was significantly and positively associated with increased odds of all subsequent transitions examined except for the transition from use to abuse. The findings highlight sensitive periods with rapid transitions to higher levels of alcohol use and emphasize the importance of cohort experiences in the full spectrum of stages of alcohol use. These results may contribute to predicting population-levels trends in alcohol-related problems in Spain.
