Exploration of motivation to be physically active among overweight adolescents in Switzerland.

Abstract

Motivation plays an important role in the field of medicine, as it significantly influences behavior change, such as becoming more physically active. This study aimed to investigate the role of motivation in engagement in a physical activity and its impact on quality of life for adolescents suffering from obesity. We assessed the time dedicated to physical activities, the type of motivation, and the relationship between those factors and their quality of life. Seventy-two adolescents aged 12-18 years (51% girls) participated in the study. Fifteen percent of the sample (11/72) were overweight, 56% (n = 40) were affected by obesity and 29% (n = 21) by severe obesity. We found that adolescents were mostly driven to engage in physical activity by self-determined motivation, but those affected by severe obesity were more motivated by external factors. Moreover, there was a disparity in physical activity engagement between genders, with boys being more active than girls. Finally, our data demonstrated that physical exercise contributed to improving quality of life of our population. This study demonstrates that self-determined motivation plays a significant role in promoting physical activity among adolescents with overweight or obesity, with notable differences between genders. Encouraging intrinsic motivation can improve physical functioning and quality of life.
