Introduction

A protective role of leisure time physical activity with regard to non-communicable chronic diseases (NCDs) is well established. However, shapes of dose-response relationships and the extent of BMI mediation between physical activity and disease risk are not well known. Furthermore, the knowledge about risk reductions from active commuting is limited.

Methods

Meta-analyses of prospective cohort studies published from January 1990 to June 2019 were conducted, 1) to assess the effect of leisure time and commuting physical activity on cardiovascular disease (CVD), type 2 diabetes, breast cancer and colon cancer, and 2) to quantify the extent to which adjustment for BMI affect these relations.

Results

Random effect meta-analyses of 59 prospective cohort studies estimated that individuals who engaged in 11.25 MET-hours/week of active commuting had a decreased risk of myocardial infarction (MI) by 18% (95% CI: 1–33%) and type 2 diabetes by 22% (95% CI: 4–37%) compared with non-commuters. Corresponding risk reductions for leisure-time physical activity (LTPA) were 22% for MI, 26% for CVD, 27% for heart failure, 23% for stroke, 22% for type 2 diabetes, 15% for colon cancer and 7% for breast cancer. Except for breast cancer, adjustment for BMI reduced the benefit of physical activity.

Conclusion

Both active commuting and LTPA are associated with lower risk for NCD. Currently, available data is insufficient to establish detail and reliable dose-response curves.

休闲时间和通勤体育锻炼对健康的益处:对发病率影响的荟萃分析

介绍

闲暇时间体育锻炼对非传染性慢性病(NCD)的保护作用已得到充分确立。但是,还不了解剂量反应关系的形状以及身体活动与疾病风险之间的BMI介导程度。此外,关于主动通勤降低风险的知识是有限的。

方法

进行了1990年1月至2019年6月发表的前瞻性队列研究的荟萃分析,1)评估休闲时间和通勤体力活动对心血管疾病(CVD),2型糖尿病,乳腺癌和结肠癌的影响,以及2)量化BMI调整对这些关系的影响程度。

结果

对59项前瞻性队列研究的随机效应荟萃分析估计,每周通勤时间为11.25 MET小时的个体,其心肌梗死(MI)的风险降低了18%(95%CI:1-33%)和类型与非通勤者相比,2例糖尿病患病率高出22%(95%CI:4–37%)。相应的休闲时间体育锻炼(LTPA)风险降低:MI为22%,CVD为26%,心力衰竭为27%,中风为23%,2型糖尿病为22%,结肠癌为15%,结肠癌为7%乳腺癌。除乳腺癌外,调整BMI会降低体育锻炼的益处。

结论

主动通勤和LTPA都降低了非传染性疾病的风险。当前,可用数据不足以建立详细和可靠的剂量反应曲线。
