This study aimed to investigate longitudinal associations between physical activity levels and obesity in adults in Colombia, where participation in large amounts of light-intensity physical activity is a necessity for many people.
Participation in moderate- and vigorous-intensity physical activity was assessed from 2005 to 2009, and obesity was assessed from 2011 to 2019 in men and women from the Prospective Urban Rural Epidemiology (PURE) study. Total physical activity level was categorized as low (<600 MET·min·wk -1 ), medium (600-3000 MET·min·wk -1 ), or high (>3000 MET·min·wk -1 ; 600 MET·min·wk -1 is equivalent to 150 min of moderate activity or 75 min of vigorous activity per week). Obesity was defined as body mass index ≥30 kg·m -2 . Analyses were adjusted for age, sex, smoking, socioeconomic status, diet, alcohol, sedentary time, and sleep.
The main analysis included 3086 men and women aged 51 ± 9 yr at baseline (mean ± SD). Compared with the low physical activity group, the odds ratio (95% confidence interval) for obesity was 0.67 (0.53-0.85) in the medium physical activity group and 0.78 (0.62-0.98) in the high physical activity group after adjustment for potential confounders. Smoking is probably a major confounder, and it is noteworthy that similar associations were observed in participants who reported never smoking.
The PURE study is the only prospective cohort study in Colombia. The present analysis is important because it suggests that even the busy people of Colombia could substantially reduce their risk of obesity by participating in moderate- and vigorous-intensity physical activity.
本研究旨在调查哥伦比亚成年人中身体活动水平与肥胖之间的纵向关联，在哥伦比亚，许多人都需要大量进行低强度身体活动。
Prospective Urban Rural Epidemiology（PURE）研究于 2005 年至 2009 年期间评估了参与者的中高强度身体活动参与情况，2011 年至 2019 年评估了参与者的肥胖情况。总身体活动水平分为低（<600 MET·min·wk -1 ）、中（600-3000 MET·min·wk -1 ）或高（>3000 MET·min·wk -1 ；600 MET·min·wk -1 相当于每周 150 分钟的中等强度活动或 75 分钟的剧烈强度活动）。肥胖定义为体质指数≥30 kg·m -2 。分析调整了年龄、性别、吸烟、社会经济地位、饮食、酒精、久坐时间和睡眠等因素。
主要分析纳入了基线时年龄为 51±9 岁的 3086 名男性和女性。与低身体活动组相比，中身体活动组肥胖的优势比（95%置信区间）为 0.67（0.53-0.85），高身体活动组为 0.78（0.62-0.98），调整了潜在混杂因素后。吸烟可能是一个主要的混杂因素，值得注意的是，在从未吸烟的参与者中也观察到了类似的关联。
PURE 研究是哥伦比亚唯一的前瞻性队列研究。本分析很重要，因为它表明，即使是忙碌的哥伦比亚人，通过参与中高强度身体活动，也可以大大降低肥胖的风险。
