Effect of body mass index on the association between alcohol consumption and the development of chronic kidney disease

The influence of body mass or metabolic capacity on the association between alcohol consumption and lower risks of developing chronic kidney disease (CKD) is not fully elucidated. We examined whether the body mass index (BMI) affects the association between drinking alcohol and CKD. We defined CKD as an estimated glomerular filtration rate decline < 60 mL/min/1.73 m(2) and/or positive proteinuria (>/= 1+). Participants were 11,175 Japanese individuals aged 40-74 years without baseline CKD who underwent annual health checkups. Daily alcohol consumption at baseline was estimated using a questionnaire, and the participants were categorized as "infrequent (occasionally, rarely or never)," "light (< 20 g/day)," "moderate (20-39 g/day)," and "heavy (>/= 40 g/day)." Over a median 5-year observation period, 936 participants developed CKD. Compared with infrequent drinkers, light drinkers were associated with low CKD risks; adjusted hazard ratios (95% confidence intervals) were 0.81 (0.69-0.95). Stratified by BMI (kg/m(2)), moderate drinkers in the low (< 18.5), normal (18.5-24.9), and high (>/= 25.0) BMI groups had adjusted hazard ratios (95% confidence intervals) of 3.44 (1.60-7.42), 0.75 (0.58-0.98), and 0.63 (0.39-1.04), respectively. Taken together, the association between alcohol consumption and CKD incidence was not the same in all the individuals, and individual tolerance must be considered.
