Course of Disordered Eating Behavior in Young People With Early-Onset Type I Diabetes: Prevalence, Symptoms, and Transition Probabilities
2019
Abstract Purpose The aims of this study were to analyze the prevalence and course of disordered eating behavior (DEB) in adolescents with intensively treated type I diabetes, describe differences in age-specific DEB symptoms, and identify predictors of current DEB. Methods Data were taken from 332/218 11- to 27-year-old participants (55.7% girls/women, mean age [SD] 17.8 [3.4] years, mean diabetes duration 14.9 [3.0] years) of two/three surveys of a Germany-wide longitudinal study on early-onset and long duration diabetes, respectively. A diabetes-adapted version of the SCOFF questionnaire was used to assess DEB. Both screening-based overall and age- and sex-specific prevalence of DEB and its symptoms were determined. To estimate transition probabilities between DEB states, first-order Markov transition models were implemented adjusting for previous sociodemographic, socioeconomic, and diabetes-specific covariates. Results The overall screening-based DEB prevalence among all 1,318 observations was 10.8% (95% confidence interval [CI]: 9.2%, 12.6%) with age-specific differences in symptom prevalence. Transition probabilities for developing/persistent DEB were twofold higher among female than male participants (risk ratio [RR] 2.3 [1.4, 3.9]/2.1 [1.3, 3.4]). In multiple adjusted regression, previous DEB (odds ratio [OR] 2.8 [95% CI 1.4, 5.6]), follow-up time (ORper 1-year increase 3.4 [1.4, 8.0]), and sex (ORgirls/women 2.1 [1.1, 3.9]) were the most important predictors of current DEB with further weaker associations for previous age and HbA1c. Conclusions Our results contribute to better understanding the course of DEB in patients with early-onset diabetes and emphasize the relevance of regular DEB screenings including the age group of young adults.
