Executive function, behavioral problems, and insulin resistance in adolescents with obesity

Abstract

Abstract Objectives In this study, we examined executive function (EF) abilities, behavioral and emotional (BE) issues, and overall quality of life (QoL) of adolescents with obesity and compared them with a control group and also aimed to investigate whether the presence of insulin resistance (IR) is associated with these problems. Methods This cross-sectional study included a sample of 50 adolescents aged 11–18 years with obesity and age- and gender-matched 50 normal weight adolescents who had attended and were treated at the pediatric outpatient clinic. Sociodemographic data were collected through personal interviews with the adolescents and their parents. Measurements of the height and weight, fasting blood glucose, and insulin levels of all adolescents were assessed. In addition, the participants and their parents completed the Kiddo-KINDL, the Strengths and Difficulties Questionnaire, and the Behavior Rating Inventory Scale from Executive Function. Results Of the 50 adolescents with obesity, 27 (54.0 %) were girls, and 23 (46.0 %) were boys, with a mean age of 14.06 ± 1.83 years. Adolescents with obesity have more EF deficiencies, BE difficulties, more problems in peer relationships and lower QoL scores than those without obesity. The QoL was worse in girls, adolescents with obesity, and those with IR. Adolescents with obesity and those with and without IR did not differ about EF deficiencies and BE problems. Conclusions Addressing these EF deficits and BE problems in interventions for adolescents who have difficulty adapting to lifestyle changes, an essential part of obesity treatment in clinical practice, may contribute to treatment success.
