Onset and course of alcoholism over 25 years in middle class men.

BACKGROUND

Patterns of drinking and alcohol problems change with age. However, few studies use multiple data points and detailed history spanning early adulthood to middle age. This study reports such data from 373 men in the San Diego Prospective Study.

METHODS

Data were generated at baseline (T1) at ∼age 20, and through face-to-face followup interviews ∼every 5 years in >90% of these eligible Caucasian and relatively higher educated men. Subjects were placed into 4 groups regarding their course: 62.5% with no alcohol use disorder (AUD); 17.2% with AUD onset <age 30 and a chronic course; 6.7% with onset ≥age 30 and no recovery; and 13.7% with AUD onset <age 30 and maintained remission for >5 years before the 25-year followup.

RESULTS

On a univariate level, low level of response (LR) to alcohol, family history of AUDs, and higher Novelty Seeking at ∼age 20 predicted AUDs with onset before age 30 (mean age∼25), but among these only LR predicted later onset (mean age 38) as well. Additional predictors of AUDs included demography (lower education), and greater involvement with alcohol, drugs, and nicotine prior to T1. Sustained remission from AUDs among alcoholics was predicted by lower T1 and T10 drinking frequencies, and being separated or divorced at T10, along with a trend for higher Reward Dependence.

CONCLUSION

These data indicate that information available in ages of the late teens to early twenties can help predict the future onset and course of AUDs, and underscore the importance of longitudinal studies in substance use disorders.
