Abstract
Objectives: To evaluate differences in dietary intake in diabetic GLP1-RA users and non-users and to assess if length of use was associated with differences in dietary intake. Methods: Data Source: Cross-sectional data from National Health and Nutrition Examination Survey (NHANES) from 2007-2020. Population: Adult participants >30 years of age in NHANES with diabetes who had complete and reliable dietary intake data, had complete data for confounding variables, and were not currently breastfeeding or pregnant. GLP1-RA Use: Ascertained from self-reported medication use with medication-label checking performed by trained technicians. Users were divided into short-term and long-term users based on a 1-year use cut-off. Dietary Intake: Ascertained from self-reported 24- hour recalls. Statistical Analysis: Multivariable regression models were used to adjust for gender, race/ethnicity, poverty-to-income ratio, age, body weight, and height. Food consumption was additionally adjusted for energy intake. Key Conclusions: Short-term GLP1-RA use may be associated with a lower likelihood of being nutritionally adequate for some key nutrients. Long-term users and short-term users have dietary intake patterns, which may occur from selection bias (long-term users have fewer side effects) or adaptation, which carries additional considerations for potential long-term efficacy of GLP1-RA use.
