Chunk #17 — 3. Results — 3.1 Prevalence and Mean Ages of Onset and Years to Transition — 3.1.3 Time to Progression from Initiation of Drinking to Alcohol Dependence: Race/ethnicity and Sex Differences
One fifth (20.8%) of persons reporting an age of drinking initiation (excluding lifetime abstainers) progressed to alcohol dependence. As shown in Table 1, the mean time from initiation of drinking to the development of alcohol dependence was 5.19 years. Similar to age at first episode of dependence, there were no sex differences overall or by race/ethnicity. White men and women had a shorter mean time from onset of drinking to development of dependence than Black men (F1,714 = 10.00; p = 0.002) and women (F1, 598 = 12.93; p < 0.001), respectively. Hispanics were not significantly different from Whites or Blacks.
