OBJECTIVE
To assess the influence of BMI group (lean/overweight/obese) and gender on the postural sway of adults and adolescents during quiet upright stance.
METHODS
90 women and 90 men, aged 12 to 67 years old, accepted to participate. The center of pressure during quiet upright stance was recorded using a force platform, during 4 conditions (eyes open/closed on hard/soft surface). Statistical analysis was performed using multivariate analysis of covariance.
RESULTS
During recordings on hard surface, closing the eyes produced a larger increase of sway on obese subjects than on lean and overweight subjects, with a larger increase on the length and the area of sway. Although gender differences were found during the four sensory conditions, no interaction was observed between the BMI group and the gender. These results were not related to the age of the subjects.
CONCLUSION
Compared to non-obese subjects, the postural stability of obese subjects may be more vulnerable when vision is not available, with no influence of the gender.
目的
评估 BMI 组别（消瘦/超重/肥胖）和性别对成年人和青少年在安静直立姿势下姿势摆动的影响。
方法
90 名女性和 90 名男性，年龄 12 至 67 岁，同意参与。使用力平台记录安静直立姿势期间的中心压力，记录在 4 种条件（睁眼/闭眼于硬/软表面）下进行。使用协方差的多变量分析进行统计分析。
结果
在硬表面记录期间，与消瘦和超重受试者相比，肥胖受试者闭眼时的摆动幅度增加更大，摆动长度和面积的增加更大。尽管在四种感觉条件下都发现了性别差异，但在 BMI 组别和性别之间没有观察到相互作用。这些结果与受试者的年龄无关。
结论
与非肥胖受试者相比，肥胖受试者的姿势稳定性在没有视觉的情况下可能更脆弱，性别没有影响。
