Alcohol: Intake, consequences and neurological complications. results from the atahualpa project

Information about the burden and consequences of alcohol intake in rural communities of Latin America is scarce. This study aims to assess the magnitude of alcohol intake in Atahualpa as well as its consequences and prevalence of neurological complications. Male residents aged ≥40 years (n=277) were interviewed with a structured questionnaire designed to evaluate prevalence, drinking patterns and consequences of chronic alcohol intake. Most of them were current drinkers and 40% started drinking below the legal age (18 years). Weekly binge drinking were admitted by 81% individuals, 58% referred physical consequences related to alcohol intake, 59% had social consequences, and 51% recognized alcohol intake as a major economic burden. Individuals who started drinking below the legal age were more often involved in binge drinking and consumed more alcohol than those aged ≥18 years at first regular drink. The relationship between alcohol intake and alcoholic cerebellar degeneration was evaluated by the use of the BARS scale, with 14.6% of individuals having clinically relevant alcoholic cerebellar degeneration. Predictive models showed significant relationships between BARS score margins and years of drinking and the amount of alcohol intake. Our study also provided robust evidence favoring an independent and synergistic effect of age and years of drinking in the relationship between ACD and cognitive decline. This study shows a high prevalence of chronic alcohol intake in community-dwelling men living in Atahualpa.
