abstract="BACKGROUND: We aimed to identify different categorical phenotypes based upon the DSM-V criteria of alcohol use disorders (AUD) among alcohol users who had at least one drink per week in the past year (n=948). METHODS: Data are from the São Paulo Megacity Mental Health Survey collected in 2005-2007, as part of the World Mental Health Survey Initiative. A latent class analysis of the 11 DSM-5-AUD criteria was performed using Mplus, taking into account complex survey design features. Weighted logistic regression models were used to examine demographic correlates of the DSM-5-AUD latent classes. RESULTS: The best latent-class model was a three-class model. We found a &quot;non-symptomatic class&quot; (69.7%), a &quot;use in larger amounts class&quot; (23.2%), defined by high probability (>70%) of the &quot;use in larger amounts&quot; criterion only, and a &quot;high-moderate symptomatic class&quot; (7.1%), defined by high-moderate probability of all the 11 AUD criteria. Compared to those in the non-symptomatic class, individuals in the &quot;high-moderate symptomatic class&quot; were more likely to have been married, have lower educational attainment and to be unemployed or in non-regular/informal employment. Those on the &quot;use in larger amounts class&quot; were more likely to have been married or never married. CONCLUSION: The two symptomatic classes clearly represented the dimensionality of the new proposed AUD criteria, and could be more specifically targeted by different prevention or treatment strategies. DSM-5-AUD has the advantage of shedding light on risky drinkers included in the &quot;use in larger amounts class&quot;, allowing for preventive interventions, which will reach a large number of individuals.<p /> <p>Language: en</p>",
