This study examined prevalence of alcohol dependence symptoms and diagnosis  among a nationally representative sample of recent onset adolescent drinkers  aged 12-21 years (mean 17 years) across different levels of drinking drawn from  National Survey of Drug Use and Health (N = 9,490).
We assessed whether the  relationship between level of alcohol use and alcohol dependence was similar for  individuals from different socio-demographic groups (i.e., gender, age group,  ethnic group, family income, and substance use in the past year).
The most  prevalent DSM-IV alcohol dependence criteria at low levels of alcohol use were  “unsuccessful efforts to cut down”, “tolerance”, and “time spent” in activities  necessary to obtain alcohol or recover from its effect.
Logistic regression with  polynomial contrasts indicated increasing rates of each criterion and an overall  dependence diagnosis with increasing alcohol exposure that differed most between  the lowest levels of recent drinking frequency.
After controlling for drinking  quantity, younger adolescents, females, Native American/Alaskans and  Asian/Pacific Islanders were most likely to experience alcohol dependence  symptoms and a diagnosis of dependence, suggesting that these demographic  subgroups may experience dependence symptoms or develop dependence more quickly  after beginning to drink.
Recognizing early symptoms of alcohol dependence may assist in early identification and intervention of those at risk for heavier drinker in the future.
