Abstract
Objective: To investigate the association between dietary adherence and glycemic control among youth with type 1 diabetes.
Research Design And Methods: We conducted a cross-sectional analysis of 119 youth ages 9-14 years (12.1± 1.6) with diabetes duration ≥1 year (5.4± 3.1). Dietary adherence was assessed using the Diabetes Self-Management Profile (DSMP) diet domain. Higher score defined greater dietary adherence. Glycemic control was determined by A1C.
Results: Dietary adherence score was inversely correlated with A1C (r=-.36, p<.0001). In a multivariate model (R2=.34, p<.0001), dietary adherence (p=.004), pump use (p=.03), and caregiver education (p=.01) were associated with A1C. A1C of youth in the lowest (9.0%) tertile of diet score was higher than the A1C of youth in the middle (8.1%, p=.004) and upper (8.4%, p=.06) tertiles. Dietary adherence uniquely explained 8% of the variance in A1C in the model.
Conclusions: Greater dietary adherence was associated with lower A1C among youth with type 1 diabetes.
