Abstract:

$\textbf{Background:}$
Children with underweight or overweight show different physical activity (PA) levels than their peers with normal weight, and PA enjoyment may explain this difference. This cross-sectional study examined whether PA enjoyment mediates the association between weight status and PA in children and adolescents who are overweight or underweight compared to those with normal weight.

$\textbf{Methods:}$
We analysed questionnaire-based data from 3,718 participants (52.4% male, mean age 10.4 ± 3.7 years) and accelerometer-based data from 1,531 participants (52.1% male, mean age 10.7 ± 3.6 years) of the nationwide MoMo 2.0-Study in Germany (2023–2024). Weight status was categorized according to cut-offs of the International Obesity Task Force into underweight, normal weight, and overweight. PA enjoyment was measured with the short version of the Physical Activity Enjoyment Scale, PA was assessed via MoMo-Physical Activity Questionnaire and with accelerometers (activPAL4). Mediation analyses were performed using Hayes PROCESS mediation macro for total, direct, and indirect effects, adjusted for age, sex, and socioeconomic status.
