EV0653 E-PosterAddictionProspective cohort # Low-level alcohol consumption and incident depression among Mexican female teachers: a prospective cohort analysis of 73,915 women LOW-LEVEL ALCOHOL CONSUMPTION AND INCIDENT DEPRESSION IN MEXICAN FEMALE TEACHERS: A PROSPECTIVE COHORT ANALYSIS OF 73,915 WOMEN Presenter: Silvia G. Bennett Carreño Country: Mexico Institution: National Medical Center "20 de Noviembre", Department of Psychiatry No level of alcohol consumption was risk-free; even 1 drink per month was associated with a significant increase in the odds of incident depression and a clear dose–response trend. The aim was to determine whether even low-level alcohol consumption increases the odds of incident depression in a population with historically low consumption, by comparing true abstainers with light drinkers. The study was conducted prospectively within the Mexican Teachers’ Cohort (ESMaestras), comprising 115,315 female teachers recruited across 12 states between 2006 and 2010; the analysis included 73,915 teachers aged 25 to 74 who were free of depression at baseline (2006 and 2008). Follow-up took place in 2011 and 2014, with a follow-up rate of 82.9%; exposure was measured using a validated food frequency questionnaire (FFQ) (1 drink = 13 g of ethanol; no consumption, 1 per month, 2 to 3 per month, and 4 or more per month), and the outcome was defined as a PHQ-9 score of 10 or higher (2011), a physician diagnosis, or initiation of antidepressant treatment after 2008. Three logistic regression models were constructed: Model 1 included sociodemographic variables (marital status, ethnicity, region, socioeconomic status, and education); Model 2 additionally included biological variables (parity, comorbidities, and menopausal status); and Model 3 further added behavioral variables (sleep behavior and smoking). There were 3,069 cases (9.8%) among abstainers, who served as the reference group (OR 1.00); among those consuming 1 drink per month, there were 1,352 cases (10.3%), with an odds ratio of 1.18 (95% CI 1.11 to 1.27); among those consuming 2 to 3 drinks per month, there were 2,072 cases (10.4%), with an odds ratio of 1.20 (1.13 to 1.28); and among those consuming 4 or more drinks per month, there were 995 cases (10.4%), with an odds ratio of 1.32 (1.23 to 1.42). Strengths of the study include the use of a validated FFQ and PHQ-9 (Cronbach’s alpha = 0.89 in the Mexican Teachers’ Cohort validation), as well as distinguishing true abstainers from light drinkers to limit “sick-quitter” bias. In conclusion, even low-level alcohol consumption was associated with a statistically significant, dose-dependent increase in the odds of incident depression among Mexican women; these findings challenge the assumption of a risk-free threshold for low-level consumption with respect to mental health and have public health implications for clinical counseling in populations with low baseline consumption.
