title: Weight trajectory of youth with new-onset type 1 diabetes comparing standard and enhanced dietary education.
abstract: Youth with type 1 diabetes (T1DM) gain weight after insulin therapy initiation. We aimed to study the effects of Enhanced Dietary Counseling (EDC) compared to Standard of Care Dietary Counseling (SDC) on BMI trajectory in youth with new-onset T1DM. Youth with new-onset T1DM (n = 47; 8.9 + 4.2 years) were randomized 6 weeks post-diagnosis to either SDC per American Diabetes Association guidelines (n = 25) or EDC (n = 22: SDC plus monthly nutritional education and 3-day food records (FRs) at 6 and 24 weeks). Weights and heights were measured at diagnosis, 6 weeks, 3, 6, and 12 months post-diagnosis; pre-diagnosis BMI was obtained from pediatricians' records. BMI Z score was used to track BMI change. Knowledge of recommended daily energy intake (DEI) and daily carbohydrate intake was assessed at follow-up visits. Changes in BMI Z scores were similar in SDC versus EDC subjects from pre-diagnosis to 12 months post-diagnosis. BMI Z score at 12 months exceeded pre-diagnosis level in 58.5 % subjects (54.5 % EDC vs. 63.1 % SDC, p = 0.75). From 6 weeks to 6 months, percentage of subjects correctly recalling recommended DEI increased in EDC along with percentage of subjects meeting recommended daily fruit servings intake from 25 % (6 weeks) to 64 % (6 months), p = 0.047). EDC did not prevent BMI Z score increases in youth with new-onset T1DM, and BMI Z score exceeded pre-diagnosis levels in >50 % 12 months post-diagnosis. A family-based approach and/or additional intervention may be needed to prevent excessive weight gain.
