Abstract

BACKGROUND

This study aimed to explore association of self-reported physical activity domains of work, leisure, and transport-related physical activity and body mass index (BMI) in 9388 adult men and women from the Africa-Wits-INDEPTH partnership for Genomic (AWI-Gen) study in Africa. Africa-Wits-INDEPTH partnership for Genomic is a large, population-based cross-sectional cohort with participants from 6 sites from rural and urban areas in 4 sub-Saharan African countries.

METHODS

A sex-stratified meta-analysis of cross-sectional data from men and women aged 29-82 years was used to assess the association of physical activity with BMI.

RESULTS

Overall, meeting physical activity guidelines of at least 150 minutes per week was associated with 0.82 kg/m2 lower BMI in men (β = -0.80 kg/m2; 95% confidence interval [CI], -1.14 to -0.47) and 0.68 kg/m2 lower BMI in women (β = -0.68 kg/m2; 95% CI, -1.03 to -0.33). Sex and site-specific differences were observed in the associations between physical activity domains and BMI. Among those who met physical activity guidelines, there was an inverse association between transport-related physical activity and BMI in men from Nanoro (Burkina Faso) (β = -0.79 kg/m2; 95% CI, -1.25 to -0.33) as well as work-related physical activity and BMI in Navrongo men (Ghana) (β = -0.76 kg/m2; 95% CI, -1.25 to -0.27) and Nanoro women (β = -0.90 kg/m2; 95% CI, -1.44 to -0.36).

CONCLUSIONS

Physical activity may be an effective strategy to curb rising obesity in Africa. More studies are needed to assess the impact of sex and geographic location-specific physical activity interventions on obesity.

摘要

背景

本研究旨在探讨在非洲开展的非洲 - 威特沃特斯兰德大学 - 深入基因组学伙伴关系（AWI - Gen）研究中，9388名成年男性和女性自我报告的工作、休闲及交通相关身体活动领域与体重指数（BMI）之间的关联。非洲 - 威特沃特斯兰德大学 - 深入基因组学伙伴关系是一项大型的基于人群的横断面队列研究，参与者来自撒哈拉以南非洲4个国家农村和城市地区的6个地点。

方法

对年龄在29 - 82岁的男性和女性的横断面数据进行性别分层的荟萃分析，以评估身体活动与BMI之间的关联。

结果

总体而言，每周至少进行150分钟的身体活动与男性BMI降低0.82kg/m²相关（β = -0.80kg/m²；95%置信区间[CI]，-1.14至-0.47），与女性BMI降低0.68kg/m²相关（β = -0.68kg/m²；95%CI，-1.03至-0.33）。在身体活动领域与BMI之间的关联中观察到了性别和特定地点的差异。在达到身体活动指南的人群中，来自布基纳法索纳诺罗的男性的交通相关身体活动与BMI之间存在负相关（β = -0.79kg/m²；95%CI，-1.25至-0.33），加纳纳夫龙戈的男性的工作相关身体活动与BMI之间存在负相关（β = -0.76kg/m²；95%CI，-1.25至-0.27），纳诺罗的女性的工作相关身体活动与BMI之间存在负相关（β = -0.90kg/m²；95%CI，-1.44至-0.36）。
