Almost 80% of deaths from non-communicable diseases (NCDs) occur in low- and middle-income countries. Physical inactivity is a key risk factor for NCDs. Enhancing understanding of the scientific evidence linking physical activity and health in low- and middle-income countries is important for supporting national efforts to promote physical activity and reduce NCDs in these countries. A systematic review of three electronic databases was conducted in July 2013, including large population-based epidemiological studies with adult participants, conducted in low- and middle-income countries, and published in the past 30 years. Physical activity was consistently associated with a reduced risk of all-cause mortality, cardiovascular disease (CVD), diabetes and several types of cancer. Positive associations were also found between physical activity and body composition (including overweight and obesity), blood pressure, cholesterol, metabolic indices and bone mineral density. Overall, the results confirm that the epidemiological research into the health benefits of physical activity in low- and middle-income countries is consistent with previous research conducted in high-income countries. This summary of the available research can be used as an advocacy tool in low- and middle-income countries to support greater prominence of physical activity in NCD policies.
近 80%的非传染性疾病（NCDs）死亡发生在中低收入国家。身体活动不足是非传染性疾病的一个主要危险因素。加强对中低收入国家身体活动与健康之间科学证据的理解，对于支持这些国家促进身体活动和减少非传染性疾病的国家努力非常重要。2013 年 7 月对三个电子数据库进行了系统审查，包括过去 30 年在中低收入国家进行的、有成年人参与的大型基于人群的流行病学研究。身体活动与全因死亡率、心血管疾病（CVD）、糖尿病和几种癌症的风险降低呈一致相关。身体活动与身体成分（包括超重和肥胖）、血压、胆固醇、代谢指数和骨矿物质密度之间也存在正相关关系。总的来说，这些结果证实了在中低收入国家进行的身体活动对健康益处的流行病学研究与在高收入国家进行的先前研究是一致的。本研究的总结可作为中低收入国家的宣传工具，以支持在非传染性疾病政策中更加突出身体活动的地位。
