Consuming a low or moderate amount of alcohol may reduce the risk of developing chronic kidney disease

In January 2020 researchers from the USA published the results of their study to assess the association between alcohol consumption and chronic kidney disease. A total of 12,692 individuals, aged 45-64 years, were involved in the study. Information on alcohol consumption was collected via a food frequency questionnaire at the start of the study and the individuals were divided into 6 alcohol consumption categories, namely never drinkers, former drinkers, 1 drink per week, 2 to 7 drinks per week, 8 to 14 drinks per week, and over 15 drinks per week. Cronic kidney disease was defined as estimated glomerular filtration rate under 60 mL/minute/1.73 m2 accompanied by at least an estimated 25% decline in glomerular filtration rate, a kidney disease-related hospitalization or death or end-stage renal disease. During an average follow up of 24 years, a total of 3,664 diagnoses of chronic kidney disease were made. Results showed that there was no significant association between being a former drinker and risk of chronic kidney disease. Individuals who had 1 drink per week had a 12% reduced risk of chronic kidney disease compared with never drinkers, whilst those who consumed 2 to 7 drinks per week had a 20% reduced risk, 8 to 14 drinks per week a 29% reduced risk, and 15 and over drinks per week a 23% reduced risk. The researchers therefore concluded that consuming a low or moderate amount of alcohol may reduce the risk of developing chronic kidney disease.
