Data on use and health benefits of active travel in rural low- and middle- income country settings are sparse. We aimed to examine correlates of active travel, and its association with adiposity, in rural India and Bangladesh.
Cross sectional study of 2,122 adults (≥18 years) sampled in 2011-13 from two rural sites in India (Goa and Chennai) and one in Bangladesh (Matlab). Logistic regression was used to examine whether ≥150 min/week of active travel was associated with socio-demographic indices, smoking, oil/butter consumption, and additional physical activity. Adjusting for these same factors, associations between active travel and BMI, waist circumference and waist-to-hip ratio were examined using linear and logistic regression.
Forty-six percent of the sample achieved recommended levels of physical activity (≥150 min/week) through active travel alone (range: 33.1 % in Matlab to 54.8 % in Goa). This was more frequent among smokers (adjusted odds ratio 1.36, 95 % confidence interval 1.07-1.72; p = 0.011) and those that spent ≥150 min/week in work-based physical activity (OR 1.71, 1.35-2.16; p < 0.001), but less frequent among females than males (OR 0.25, 0.20-0.31; p < 0.001). In fully adjusted analyses, ≥150 min/week of active travel was associated with lower BMI (adjusted coefficient -0.39 kg/m(2), -0.77 to -0.02; p = 0.037) and a lower likelihood of high waist circumference (OR 0.77, 0.63-0.96; p = 0.018) and high waist-to-hip ratio (OR 0.72, 0.58-0.89; p = 0.002).
Use of active travel for ≥150 min/week was associated with being male, smoking, and higher levels of work-based physical activity. It was associated with lower BMI, and lower risk of a high waist circumference or high waist-to-hip ratio. Promotion of active travel is an important component of strategies to address the growing prevalence of overweight in rural low- and middle- income country settings.
关于农村低收入和中等收入国家积极出行的使用情况及其对健康益处的数据很少。我们旨在研究印度农村地区和孟加拉国积极出行的相关因素及其与肥胖的关联。
2011年至2013年在印度的两个农村地区（果阿邦和金奈）以及孟加拉国的一个农村地区（马特莱布）对2122名成年人（≥18岁）进行了横断面研究。采用逻辑回归分析每周进行≥150分钟积极出行是否与社会人口学指标、吸烟、油/黄油摄入量以及额外的体育活动有关。在对这些相同因素进行调整后，使用线性回归和逻辑回归分析积极出行与体重指数（BMI）、腰围和腰臀比之间的关联。
46%的样本仅通过积极出行就达到了推荐的体育活动水平（每周≥150分钟）（范围：马特莱布为33.1%，果阿邦为54.8%）。在吸烟者（调整后的优势比为1.36，95%置信区间为1.07 - 1.72；p = 0.011）以及每周在工作场所进行体育活动≥150分钟的人群中（优势比为1.71，1.35 - 2.16；p < 0.001）更为常见，但女性比男性少见（优势比为0.25，0.20 - 0.31；p < 0.001）。在完全调整后的分析中，每周进行≥150分钟的积极出行与较低的BMI（调整系数为-0.39 kg/m²，-0.77至-0.02；p = 0.037）以及高腰围（优势比为0.77，0.63 - 0.96；p = 0.018）和高腰臀比（优势比为0.72，0.58 - 0.89；p = 0.002）的较低可能性相关。
每周进行≥150分钟的积极出行与男性、吸烟以及较高水平的工作场所体育活动有关。它与较低的BMI以及高腰围或高腰臀比的较低风险相关。促进积极出行是解决农村低收入和中等收入国家超重患病率不断上升问题的战略的重要组成部分。
