Ventura-Cots M, et al. - Using extensive data from 193 sovereign countries, as well as 50 states and 3,144 counties in the United States, researchers evaluated whether climate has a causal effect on alcohol consumption and its weight on alcoholic cirrhosis. Data showed that the percentage of heavy episodic drinking and total drinkers among population inversely related to temperature −0.45 and −0.49 and sunshine hours −0.39 and −0.57. Findings suggested an association of liters of alcohol consumption with the alcohol-attributable fraction (AAF) in the multivariate analysis. Colder climates demonstrated a positive correlation with the age-standardized prevalence of heavy and binge drinkers in the United States. Results of this study suggested that colder climates may have a causal role on AAF mediated by alcohol consumption.
