Alcohol Consumption Patterns in Young Adults with Type 1 Diabetes: the SEARCH for Diabetes in Youth Study

Abstract Aims The objective of this study is to describe alcohol consumption behaviors of young adults with T1D and to examine associations between alcohol consumption and diabetes-related clinical markers Methods Data from 602 SEARCH for Diabetes in Youth Study participants age ≥18 yrs. with T1D were collected from 12/2011 to 6/2015 (50% female, mean age 21.3(SD 2.4), 22% race/ethnic minority). Participants were characterized as alcohol non-drinkers (n=269), drinkers but non-binge drinkers (n=167), or binge drinkers (n=166) based on reported consumption in the past 30 days. Analyses were conducted using one-way ANOVAs, chi-square tests, and logistic regression modeling to examine associations between drinking and clinical markers. Results Fifty-five percent of participants reported alcohol consumption; 27.6% of participants reported binge drinking. After adjusting for demographic characteristics, neither binge drinking nor non-binge drinking were associated with HbA1c or severe hypoglycemic events relative to non-drinkers. Binge drinking was associated with higher HDL (p=0.008), lower systolic blood pressure (p-=0.011), and a lower waist:height ratio compared to non-drinkers (p=0.013). Conclusions Young adults with T1D in the SEARCH cohort reported similar alcohol use but higher rates of binge drinking compared to the general United States population and previously reported rates in adults with T1D.
