This study aimed to associate physical activity habits with cardiometabolic variables (blood pressure, fasting glucose, HDL cholesterol, and triglycerides), body composition (body fat percentage and fat-free mass), and physical performance (handgrip strength (HGS), timed up-and-go (TUG), and walking speed) in Chilean older women. An analytical cross-sectional study analyzed 179 older women with a mean age of 75.4 years distributed into physically inactive (PI) older women ( = 74) and physically active (PA) older women ( = 105). A logistic regression showed that PI older women presented an increased risk of hyperglycemia (OR = 4.70; = 0.000), high blood pressure (OR = 3.83; = 0.000), low HDL cholesterol levels (OR = 2.13; = 0.03), hypertriglyceridemia (OR = 2.54; = 0.01), excess body fat percentage (OR = 4.33; = 0.000), low fat-free mass (OR = 2.22; = 0.02), low HGS in their dominant hand (OR = 3.37; = 0.001) and non-dominant hand (OR = 3.60; = 0.0001), and poor performance in TUG (OR = 5.60; = 0.000) and walking speed (OR = 5.52; = 0.000). In conclusion, physical inactivity was associated with increased cardiometabolic risk, excess body fat percentage, lower fat-free mass, and poorer physical performance in Chilean older women. At the same time, PA older women showed a lower cardiometabolic risk, better body composition, and better physical performance than PI older women.
本研究旨在探讨智利老年女性的体力活动习惯与心血管代谢变量（血压、空腹血糖、高密度脂蛋白胆固醇和甘油三酯）、身体成分（体脂肪百分比和去脂体重）和身体表现（握力（HGS）、计时起立行走测试（TUG）和步行速度）之间的关联。这是一项分析性横断面研究，共纳入了 179 名平均年龄为 75.4 岁的老年女性，其中 74 名为非活跃体力活动老年女性（PI），105 名为活跃体力活动老年女性（PA）。逻辑回归分析显示，PI 老年女性发生高血糖（OR=4.70； =0.000）、高血压（OR=3.83； =0.000）、低 HDL 胆固醇水平（OR=2.13； =0.03）、高甘油三酯血症（OR=2.54； =0.01）、体脂肪百分比过高（OR=4.33； =0.000）、去脂体重过低（OR=2.22； =0.02）、优势手握力较低（OR=3.37； =0.001）和非优势手握力较低（OR=3.60； =0.000）以及 TUG 表现较差（OR=5.60； =0.000）和步行速度较慢（OR=5.52； =0.000）的风险较高。总之，智利老年女性体力活动不足与心血管代谢风险增加、体脂肪百分比过高、去脂体重过低以及身体表现较差有关。同时，与 PI 老年女性相比，PA 老年女性具有较低的心血管代谢风险、更好的身体成分和更好的身体表现。
