Substantial evidence shows that physical inactivity (PI) and sedentary behavior (SB) increases the risk of many chronic diseases and shortens life expectancy. We describe evidence that certain domains of physical activity (PA) in the United States (US) population have declined substantially over 5 decades. The prevalence of PI is very high worldwide, which has contributed to 6%-10% of the burden of many chronic diseases and premature mortality. Reduction or elimination of PI would likely produce substantial increases in life expectancy of the world's population. Great efforts are needed to reduce PI and SB and increase levels of PA in the US and worldwide.
大量证据表明，身体活动不足（PI）和久坐行为（SB）会增加许多慢性疾病的风险并缩短预期寿命。我们描述了美国（US）人口中某些身体活动（PA）领域在过去 5 个十年中大幅下降的证据。全球范围内 PI 的患病率非常高，这导致了许多慢性疾病和过早死亡的负担的 6％-10％。减少或消除 PI 可能会使世界人口的预期寿命大大增加。需要付出巨大努力来减少美国和全球范围内的 PI 和 SB，并提高 PA 水平。
