Abstract：
OBJECTIVE: This study aimed to quantify the association between step count and multiple health outcomes in a healthy population.
METHODS: PubMed, Embase, Web of Science, and The Cochrane Library were systematically searched for systematic reviews and meta-analyses from inception to April 1, 2022. Literature screening, data extraction, and data analysis were performed in this umbrella review. The intervention factor was daily step counts measured based on devices. Multiple health outcomes included metabolic diseases, cardiovascular diseases, all-cause mortality, and other outcomes in the healthy population.
RESULTS: Twenty studies with 94 outcomes were identified in this umbrella review. The increase in daily step count contributed to a range of human health outcomes. Furthermore, the special population, different age groups, countries, and cohorts should be carefully considered. Negative correlation between step counts and the following outcomes: metabolic outcomes, cardiovascular diseases, all-cause mortality, postural balance, cognitive function, and mental health. However, there was no association between participation in the outdoor walking group and the improvement of systolic blood pressure and diastolic blood pressure. Analysis of the dose-response association between increasing daily step count and the risk of cardiovascular disease events and all-cause mortality showed a substantially linear relationship.
CONCLUSIONS: A wide range of health outcomes can benefit from the right number of steps.

摘要：
目的：本研究旨在量化健康人群中步数与多种健康结果之间的关联。
方法：PubMed，Embase,WebofScience,从开始到2022年4月1日，系统搜索了Cochrane图书馆的系统评价和荟萃分析。文学筛选,数据提取,并在本综述中进行了数据分析。干预因素是基于设备测量的每日步数。多种健康结果包括代谢疾病，心血管疾病,全因死亡率,以及健康人群的其他结果。
结果：本综述确定了20项研究，结果为94项。每日步数的增加促成了一系列人类健康结果。此外，特殊人群,不同年龄段,国家,和队列应该仔细考虑。步数与以下结果之间的负相关：代谢结果，心血管疾病,全因死亡率,姿势平衡,认知功能,和心理健康。然而,户外步行组的参与与收缩压和舒张压的改善之间没有关联.每日步数增加与心血管疾病事件和全因死亡率风险之间的剂量反应相关性分析显示出基本的线性关系。
结论：正确的步骤可以使各种健康结果受益。
