The purpose of the study was to examine the impact of a 12-month weight loss intervention with either a lowcarbohydrate or a low-fat diet on quality of life (QOL) among obese patients with type 2 diabetes.Methods
Participants were enrolled in a randomized trial comparing a low-carbohydrate to a low-fat diet in type 2 diabetes. QOL was assessed with the Diabetes-39 questionnaire, which measures QOL within 5 distinct scales: anxiety and worry, diabetes control, energy and mobility, social burden, and sexual functioning. Repeated measures ANOVA compared change in QOL scales at baseline and 6 and 12 months.Results
Forty-six participants completed all measures. Following 12 months, there was a significant reduction in the scores related to sexual function and energy and mobility, suggesting improvement in QOL related to these domains. These changes were not significantly different between dietary arms. Changes in weight, A1C, and dietary composition were not significantly correlated with changes in QOL.Conclusions
Participants with diabetes have various options for weight loss. Dietary interventions with either low-carbohydrate or low-fat diets may lead to some improvements in QOL in patients with type 2 diabetes.
