Disturbed eating behavior (DEB), which includes subthreshold and full-syndrome eating disorders (EDs) as well as milder eating disturbances, is more common in girls and women with type 1 diabetes than in their nondiabetic peers (1,2). DEB is associated with poorer metabolic control (1,3) and increased hospitalizations and diabetesrelated medical complications (4 -7). At baseline of the present study, there were higher rates of DEB in girls with type 1 diabetes 9 -13 years of age than in a nondiabetic control group (8 vs. 1%) (8), and baseline DEB persisted in one-half of individuals 1 year later (9). The current brief report summarizes data from baseline to 5-year follow-up. for a description of methodology. Participants were classified as normal weight, overweight, or obese using the International Obesity Task Force cutoffs for children and adolescents (10), which extrapolate BMI values of 25 and 30 kg/m 2 into the pediatric age range. Rates of DEB and ED were organized by age (in years) at the time of each assessment (Table 1). Point prevalence was calculated as all "cases" of DEB in participants of a particular age/total number assessed at that age. Similar calculations were carried out for point prevalence of ED. Cumulative prevalence includes current and/or past DEB or ED.
RESEARCH DESIGN AND METHODSRESULTS -A total of 126 girls participated at baseline (71.2% participation), 106 at 1 year (84.1%), 88 at 2 years (83.0%), 76 at 3 years (86.4%), and 98 at 5 years (77.8%). Girls who dropped out at 5 years were not more likely to have DEB at baseline than those who stayed in the study ( 2 ϭ 0.18, d.f. ϭ 1; P ϭ 0.9). Mean age was 11.8 Ϯ 1.5 years at baseline and 16.5 Ϯ 1.6 years at 5 years. Mean BMI was 20.1 Ϯ 3.2 kg/m 2 at baseline and 24.8 Ϯ 4.2 kg/m 2 at 5 years. Mean A1C was 8.3 Ϯ 1.1% at baseline and 8.5 Ϯ 1.1% at 5 years. At 5 years, 55.1% (54 of 98) of girls were classified as normal weight, 34.7% (34 of 98) as overweight, and 10.2% (10 of 98) as obese.At 5 years, 49.0% (48 of 98) of participants reported current DEB, 43.9% (43 of 98) active dietary restraint, 6.1% (6 of 98) binge-eating episodes, 3.1% (3 of 98) self-induced vomiting, 3.1% (3 of 98) insulin omission, and 25.5% (25 of 98) intense, excessive exercise for weight control. Thirteen participants (13.3%) met criteria for an ED: three girls had bulimia nervosa, three had an eating disorder not otherwise specified, and seven had a subthreshold ED. A1C was not higher in girls with DEB (8.7 vs. 8.4%; t ϭ 1.60, d.f. ϭ 91; P ϭ 0.11), although there was a trend for higher A1C in those with an ED (9.1 vs. 8.5%; t ϭ Ϫ1.75, d.f. ϭ 91; P ϭ 0.08). BMI was higher in those with DEB (26.1 vs. 23.5 kg/m 2 ; t ϭ Ϫ3.28, d.f. ϭ 96; P ϭ 0.001).Of 126 baseline participants, 64 (50.8%) reported DEB at one or more assessments. At least two assessments are available for 116 of the 126 at baseline (92.1%). Of these 116 girls, 26 (22.4%) had early DEB at baseline and/or at 1-year follow-up, and 90 (77.6%) did not. Of 26 girls, 24 (92.3%) with early DEB also reported DEB...
