Fenger KN, Andersen IG, Holm LA, et al. - Researchers conducted this cross-sectional study to explore the connection between obstructive sleep apnea (OSA) and health-related quality of life (HRQOL) in children and adolescents referred to an obesity treatment clinic. They also analyzed the link between body mass index standard deviation score (BMI SDS) and HRQOL contrasting children and adolescents with overweight or obesity without OSA with a control group of children and adolescents with normal weight without OSA. The sample consisted of 130 children and adolescents with overweight or obesity (BMI SDS > 1.28), aged 7 to 18 years, from an obesity treatment clinic. The control group consisted of 28 children and adolescents with normal weight (BMI SDS ≤ 1.28), aged 7 to 18 years, who had been selected from school. In total, 56 children and adolescents with overweight or obesity were diagnosed with OSA (43%). No connection was found between AHI or OSA and HRQOL in children and adolescents with overweight or obesity. However, in children and adolescents without OSA, a link was noted between BMI SDS and HRQOL.
