Studies have focused on obesity-induced balance instability in the older population, which has been understudied in young adults. This study aimed to determine the impact of obesity on dynamic balance in young adult Saudi males.
A cross-sectional study of 704 young adult males aged between 18 and 35 years from Umm Al-Qura University, Makkah, KSA, was performed. The obesity-induced balance was evaluated with a Biodex Balance System apparatus with a movable platform, and the overall stability index (OSI) was measured as an indicator of dynamic balance. Participants with a body mass index (BMI) ≥30 kg/m were considered obese.
The mean age and BMI of the participants was 20 years and 25.6 kg/m, respectively. The mean OSI of the entire sample was 0.9, and the OSI values increased significantly ( < 0.001) with increasing BMI. The adjusted correlation between OSI and BMI was 0.487 ( < 0.001). Logistic regression showed that for each one-unit increment in BMI, there was an expected rise of 0.115 units in the OSI value. The receiver operating characteristic curve showed that the optimal threshold of the weight and BMI cutoff points that optimized the OSI values were 18.8 kg/m and 54.5 kg, respectively, with high sensitivity and specificity values. In addition, BMI affected approximately 23% of the total variability on balance (partial eta squared = 0.227, < 0.001).
Obesity has a clear impact on dynamic balance in the selected young males. Weight management programs for obese subjects should be encouraged to optimize BMI and weight, which can attenuate balance stability.
研究主要聚焦于肥胖导致的老年人群平衡不稳定问题，而在年轻成年人中对此研究较少。本研究旨在确定肥胖对沙特年轻成年男性动态平衡的影响。
对沙特麦加乌姆古拉大学704名年龄在18至35岁之间的年轻成年男性进行了一项横断面研究。使用带有可移动平台的Biodex平衡系统仪器评估肥胖引起的平衡，测量总体稳定性指数（OSI）作为动态平衡的指标。体重指数（BMI）≥30 kg/m²的参与者被视为肥胖。
参与者的平均年龄和BMI分别为20岁和25.6 kg/m²。整个样本的平均OSI为0.9，随着BMI的增加，OSI值显著增加（P<0.001）。OSI与BMI的调整后相关性为0.487（P<0.001）。逻辑回归显示，BMI每增加一个单位，OSI值预期上升0.115个单位。受试者工作特征曲线显示，优化OSI值的体重和BMI切点的最佳阈值分别为18.8 kg/m²和54.5 kg，具有较高的敏感性和特异性值。此外，BMI影响了平衡方面约23%的总变异性（偏 eta 平方 = 0.227，P<0.001）。
肥胖对所选年轻男性的动态平衡有明显影响。应鼓励肥胖受试者的体重管理计划，以优化BMI和体重，从而减弱平衡稳定性。
