Abstract
BackgroundThe study aimed to characterize the prevalence of alcohol consumption and further investigate the relationship between alcohol consumption and type 2 diabetes mellitus (T2DM).MethodsWe studied 39,259 participants aged 18 to 79 years of the Henan Rural Cohort study. The associations between alcohol consumption and T2DM were examined using the logistic regression models and restricted cubic spline.ResultsFor men, alcohol abstinence was associated with an increased risk of T2DM (1.491(1.265, 1.758)), whereas current drinkers were not associated with T2DM (1.03(0.91, 1.15)). Further analysis of alcohol drinkers revealed that only high-risk drinkers of WHO drinking risk levels increased the risk of T2DM (1.289(1.061,1.566)) compared to never drinkers. The risk of T2DM increased as the age of starting to consume alcohol decreased and as the number of years of consuming alcohol and the alcohol intake increased only in men. We further found that the risk of T2DM decreased as the number of years of abstinence increases and no association between alcohol abstinence and T2DM was found after more than 10 years of abstinence among men.ConclusionsOur results suggested that reducing the amount of alcohol consumed and adhering to abstinence from alcohol consumption are beneficial in reducing the risk of T2DM.Trial registrationThe Henan Rural Cohort Study has been registered at Chinese Clinical Trial Register (Registration number: ChiCTR-OOC-15006699).

Highlights
The study aimed to characterize the prevalence of alcohol consumption and further investigate the relationship between alcohol consumption and type 2 diabetes mellitus (T2DM)
Similar results were observed in men, while higher proportion of overweight, lower TC and FPG were observed among women who were current drinkers compared to noncurrent drinkers (Table 1 and Table S1)
We further found that the risk of T2DM decreased as the number of years of abstinence increases and no association between alcohol abstinence and T2DM was found after more than 10 years of abstinence in men
Summary
The study aimed to characterize the prevalence of alcohol consumption and further investigate the relationship between alcohol consumption and type 2 diabetes mellitus (T2DM). Alcohol consumption is one of the leading risk factors for death and disease worldwide, and studies link its consumption to 60 acute and chronic diseases [1,2,3,4]. Per capita alcohol consumption in China rose from 4.1 l in 2005 to 7.1 l in 2010, which was higher than the world average [4]. Alcohol consumption is very common during important festivals, business occasions, ceremonies, and special events in China. The Survey on the Health and Nutrition Status of the Chinese Population showed that the alcohol consumption rate in China in the past year was about 34% [6]. Alcohol consumption is a normal part of the daily diet, especially in rural areas of China
