Abstract

OBJECTIVE

Menopause status has been associated with weight gain and increased central adiposity. Obesity and postural instability are related to an increased risk of falls. The purpose of our study was to analyze the association of body weight and body fat distribution with postural balance and their correlation with falls in postmenopausal women.

METHODS

A cross-sectional, observational study was conducted on 100 postmenopausal women aged 50 to 65 years with at least 12 months of amenorrhea. The participants were divided into obese, overweight, and normal-weight groups according to their body mass index (BMI) and into android, uniform, and gynoid body fat distribution types according to waist-to-hip ratio. Postural stability was assessed with force platforms. χ and Kruskal-Wallis tests were used for statistical analysis.

RESULTS

A total of 18 participants reported falls in the previous 12 months. The obese group had significantly higher values for the root-mean-square amplitude of the center of pressure in the posteroanterior direction under both eyes-open and eyes-closed conditions (P = 0.005 and P = 0.007, respectively), as well as for the velocity of center-of-pressure displacements (P = 0.032). In the android group, most stabilometric parameters under the condition "eyes open and standing on a foam surface" were significantly higher, whereas greater values were observed in the uniform-type group with eyes closed. A BMI of 25 kg/m or higher (odds ratio, 3.58; 95% CI, 1.07-11.9; P = 0.038) and android body fat distribution (odds ratio, 5.35; 95% CI, 1.75-16.39; P = 0.003) were correlated with the risk of falling.

CONCLUSIONS

Postural instability is associated with obesity and uniform and android body fat distribution types (waist-to-hip ratio > 0.76) in Spanish postmenopausal women aged 50 to 65 years. Our results also suggest that a BMI of 25 kg/m or higher and android body fat distribution can be considered as independent risk factors for falls.

摘要

目的

绝经状态与体重增加和中心性肥胖有关。肥胖和姿势不稳与跌倒风险增加有关。我们的研究目的是分析体重和体脂分布与姿势平衡的关系，以及它们与绝经后妇女跌倒的相关性。

方法

对 100 名年龄在 50 至 65 岁、绝经至少 12 个月的绝经后妇女进行横断面、观察性研究。根据体重指数（BMI）将参与者分为肥胖组、超重组和正常体重组，根据腰臀比分为安卓体型、均匀体型和女性型体脂分布类型。使用力台评估姿势稳定性。使用 χ 和 Kruskal-Wallis 检验进行统计分析。

结果

共有 18 名参与者报告在过去 12 个月内跌倒。肥胖组在睁眼和闭眼条件下，后前方向的中心压力均方根振幅显著升高（分别为 P = 0.005 和 P = 0.007），压力中心速度也显著升高（P = 0.032）。在安卓体型组中，“睁眼站在泡沫表面”条件下的大多数稳定参数显著升高，而在闭眼时均匀体型组的数值更高。BMI 为 25 kg/m 或更高（比值比，3.58；95%可信区间，1.07-11.9；P = 0.038）和安卓体脂分布（比值比，5.35；95%可信区间，1.75-16.39；P = 0.003）与跌倒风险相关。
