Physical activity patterns in adults: prevalence and associated factors

Abstract Background Insufficient practice of physical activity associated with some factors related to life habits increase the risk of non-transmissible chronic diseases and reduce quality of life. Objective Identify the pattern of physical activity and associated factors in adults aged ≥20 years. Method A cross-sectional, population survey conducted with 600 individuals. Data on demographic, socioeconomic and behavioral aspects, work, and physical activities were collected through home interviews. Descriptive, bivariate and Poisson regression analyses were performed. Results Prevalence of insufficient physical activity was 35.0% (95% CI: 31.2-38.9). Zero to four years of schooling [PR=2.35; 95% CI: 1.07-5.15], working in sitting position [PR=1.52; 95% CI: 1.02-2.48], and number of days at the computer [PR=4.60; 95% CI: 2.38-14.28] remained in the final model for females, whereas 0-4 years [PR=2.30; 95% CI: 1.21-4.06] or 5-8 years [PR=3.70; 95% CI: 0.79-4.00] of schooling, working in sitting position [PR=2.22 95% CI: 1.36-3.62], number of days at the computer [PR=2.04; 95% CI: 1.26-3.32], and number of days of TV viewing [PR=2.12; 95% CI: 1.03-4.36] remained in the final model for males. Conclusion High prevalence of insufficient practice of physical activity is associated with schooling, working in sitting position, and number of days at the computer and TV viewing.

摘要

背景：缺乏身体活动，加之与生活习惯相关的多项因素，会增加非传染性慢性病的发病风险并降低生活质量。

研究目的：明确20岁及以上成年人的身体活动模式及其相关影响因素。

研究方法：本研究采用横断面人群调查设计，共纳入600名研究对象。通过入户访谈收集人口学特征、社会经济状况、行为习惯、工作情况及身体活动相关数据，随后开展描述性分析、双变量分析及泊松（Poisson）回归分析。

研究结果：身体活动不足的患病率为35.0%（95%置信区间（95% CI）：31.2~38.9）。女性最终回归模型中保留的影响因素包括：受教育年限0~4年[相对危险度（PR）=2.35；95%CI：1.07~5.15]、坐位工作[PR=1.52；95%CI：1.02~2.48]及使用电脑的天数[PR=4.60；95%CI：2.38~14.28]；男性最终回归模型中保留的影响因素包括：受教育年限0~4年[PR=2.30；95%CI：1.21~4.06]或5~8年[PR=3.70；95%CI：0.79~4.00]、坐位工作[PR=2.22；95%CI：1.36~3.62]、使用电脑的天数[PR=2.04；95%CI：1.26~3.32]及看电视的天数[PR=2.12；95%CI：1.03~4.36]。

研究结论：身体活动不足的高患病率与受教育程度、坐位工作、使用电脑的天数及看电视的天数密切相关。
