          Abstract

          Researchers examining injection drug users (IDUs) in drug treatment have been trying for decades to determine the optimal way to intervene to prevent the transmission and spread of human immunodeficiency virus (HIV) in this population. Although efficacious HIV risk reduction interventions are widely available, questions remain about what specific factors are most related to HIV risk behavior and defined as unprotected sexual activity and/or high risk drug use. This review involved an evaluation of the research literature in order to better understand the association between drug use and sexual behavior debut on HIV risk behavior. Findings suggest that drug use debut and sexual behavior debut may be related to subsequent HIV risk behavior. Evidence to date implies that intervening at an earlier age to assist youth to avoid or delay these high risk behaviors may be an additional means of reducing subsequent HIV risk.

          Age at drinking onset and alcohol dependence: age at onset, duration, and severity.

          To examine whether starting to drink at an early age is associated with developing alcohol dependence at a younger age and chronic relapsing dependence, controlling for respondent demographics, smoking and illicit drug use, childhood antisocial behavior and depression, and family alcoholism history. Cross-sectional survey. Nationwide face-to-face survey with a multistage probability sample. A total of 43,093 adults were surveyed in 2001-2002. Based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria, lifetime alcohol dependence, dependence within 10 years of starting drinking, multiple episodes, an alcohol dependence episode in the past year, episodes exceeding 1 year, and meeting 6 or 7 dependence criteria. Relative to respondents who began drinking at 21 years or older, those who began drinking before age 14 years were more likely to experience alcohol dependence ever and within 10 years of first drinking (adjusted hazard ratios and 95% confidence intervals [CIs], 1.78 [1.51-2.11] and 1.69 [1.38-2.07], respectively). They also more often experienced past-year dependence and multiple dependence episodes (adjusted odds ratios, 1.93 [95% CI, 1.40-2.64] and 3.09 [95% CI, 2.19-4.35], respectively). Among alcohol-dependent persons, the odds were 2.62 (95% CI, 1.79-3.84) for having at least 1 episode exceeding 1 year and 2.89 (95% CI, 1.97-4.23) for meeting 6 or 7 dependence diagnostic criteria. There is a need to screen and counsel adolescents about alcohol use and to implement policies and programs that delay alcohol consumption.

            Age at first alcohol use: a risk factor for the development of alcohol disorders.

            This study aimed to describe the natural course of DSM-III-R alcohol disorders as a function of age at first alcohol use and to investigate the influence of early use as a risk factor for progression to the development of alcohol disorders, exclusive of the effect of confounding influences. Data were obtained from a community sample (N=5,856) of lifetime drinkers participating in the 1990-1991 Mental Health Supplement of the Ontario Health Survey. Survival analyses revealed a rapid progression to alcohol-related harm among those who reported having their first drink at ages 11-14. After 10 years, 13.5% of the subjects who began to drink at ages 11 and 12 met the criteria for a diagnosis of alcohol abuse, and 15.9% had a diagnosis of dependence. Rates for subjects who began to drink at ages 13 and 14 were 13.7% and 9.0%, respectively. In contrast, rates for those who started drinking at ages 19 and older were 2.0% and 1.0%. Unexpectedly, a delay in progression to harm was observed for the youngest drinkers (ages 10 and under). Hazard regression analyses revealed a nonlinear effect of age at first alcohol use, marked by an elevated risk of developing disorders among subjects first using alcohol at ages 11-14. First use of alcohol at ages 11-14 greatly heightens the risk of progression to the development of alcohol disorders and therefore is a reasonable target for intervention strategies that seek to delay first use as a means of averting problems later in life.

              Age at first drink and the first incidence of adult-onset DSM-IV alcohol use disorders.

              Existing studies of the association between age at first drink (AFD) and the risk of alcohol use disorders (AUD) suffer from inconsistent levels of control and designs that may inflate associations by failure to control for duration of exposure to risk. This study examined associations between AFD (ages <15 and 15-17 vs. 18+ years) and first incidence of DSM-IV alcohol dependence, abuse, and specific AUD criteria over a 3-year follow-up in a longitudinal study of U.S. drinkers 18 years of age and older at baseline (n = 22,316), controlling for duration of exposure, family history, and a wide range of baseline and childhood risk factors. After adjusting for all risk factors, the incidence of dependence was increased for AFD <15 years (OR = 1.38) and for women only with AFD at ages 15 to 17 (OR = 1.54). The incidence of abuse was increased at AFD <15 and 15 to 17 years (OR = 1.52 and 1.30, respectively). Most dependence criteria showed significant associations with AFD, but hazardous drinking and continued drinking despite interpersonal problems were the only abuse criteria to do so. All associations were nonsignificant after controlling for volume of consumption, except that AFD at all ages <18 combined was associated with a reduced likelihood of impaired control, and AFD at ages 15 to 17 was associated with lower odds of drinking more/longer than intended among heavy-volume drinkers. In a population of low-risk drinkers that excluded those with positive family histories, personality disorders, and childhood risk factors, there were strong associations between early AFD (<18) and the incidence of dependence (OR = 3.79) and continued drinking despite physical/psychological problems (OR = 2.71), but no association with incidence of abuse. There is a robust association between AFD and the risk of AUD that appears to reflect willful rather than uncontrolled heavy drinking, consistent with misuse governed by poor decision-making and/or reward-processing skills associated with impaired executive cognitive function (ECF). Additional research is needed to determine causality in the role of impaired ECF, including longitudinal studies with samples of low-risk adolescents.
