Abstract

Background: Weight abnormalities are a growing global health concern, particularly among adolescents. While the association between weight abnormalities and postural instability has been explored in various populations, its impact on adolescent postural control remains less understood. Purpose: This study aimed to compare the effect of 
different weight statuses and postural control in adolescents. Methods: Two hundred adolescents ranging from 16 to 18 years were categorized into normal weight, obese, overweight, and underweight groups based on body mass index (BMI) percentiles. Postural stability was assessed using a force platform, measuring the anteroposterior (AP) and mediolateral (ML) sway length range of the center of pressure (COP) trajectory and average COP speed. Results: Obese, overweight, and underweight adolescents exhibited significant increased AP sway compared to their normal-weight peers, while there was no significant difference between the obese and overweight groups. Obese and 
underweight adolescents exhibited significantly greater ML sway compared to their normal-weight peers, while there was no significant difference between the normal and overweight groups. Conclusion: The findings indicate a strong association between weight abnormalities (obesity, overweight, or underweight) and impaired postural  stability in adolescents. Increased or decreased body weight and altered body geometry likely contribute to these postural deficits. Early identification and targeted interventions are crucial for addressing postural instability in this population.
