To analyze the correlation between arm muscle area and handgrip strength among postmenopausal community dwelling low-income women in order to provide an easy anthropometric indicator to assess muscle mass quantity and quality.
This was a cross-sectional study involving postmenopausal women ( = 171) from three urban-marginal communities of Guayaquil, Ecuador. Corrected arm muscle area was calculated using the Frisancho formula. Dynapenia was defined as HGS < 16 kg. Spearman's correlation coefficient was calculated at a 5% significance level to test the correlation between corrected arm muscle area and handgrip strength.
Median (interquartile range: IQR) age of the sample was 72.0 years (17.0). The median of corrected arm muscle area was 34.8 cm (20.7). The overall prevalence of dynapenia was 57.9% ( = 99). There was a significant decreasing trend with age regarding all anthropometric characteristics and handgrip strength, as well as a higher prevalence of dynapenia with age. For the whole sample, a statistically significant positive correlation was found between corrected arm muscle area and handgrip strength [ = 0.267; < .001].
There was a significant yet weak positive correlation between corrected arm muscle area and handgrip strength in this postmenopausal sample. There is a need for additional research in this regard.
分析绝经后社区低收入女性的手臂肌肉面积与握力之间的相关性，以便提供一种易于测量的人体测量指标来评估肌肉质量的数量和质量。
这是一项横断面研究，涉及厄瓜多尔瓜亚基尔三个城市边缘社区的绝经后妇女（ = 171）。使用 Frisancho 公式计算校正后的手臂肌肉面积。握力下降定义为 HGS < 16 kg。在 5%的显著性水平下计算 Spearman 相关系数，以测试校正后的手臂肌肉面积与握力之间的相关性。
样本的中位数（四分位距：IQR）年龄为 72.0 岁（17.0）。校正后的手臂肌肉面积中位数为 34.8 cm（20.7）。握力下降的总体患病率为 57.9%（ = 99）。所有人体测量特征和握力均随年龄呈显著下降趋势，且握力下降的患病率随年龄增长而增加。对于整个样本，校正后的手臂肌肉面积与握力之间存在显著的正相关关系[ = 0.267； < .001]。
在这个绝经后样本中，校正后的手臂肌肉面积与握力之间存在显著但较弱的正相关关系。在这方面需要进一步的研究。
