To describe the worldwide prevalence of physical inactivity and to analyze its association with development level of each country.
Pooled analysis of three multicenter studies, conducted between 2002 and 2004, which investigated the prevalence of physical inactivity in 76 countries, and comprised almost 300,000 individuals aged 15 years or older. Each study used the International Physical Activity Questionnaire to assess physical inactivity. The level of development of each country was analyzed by the Human Development Index (HDI).
The crude worldwide prevalence of physical inactivity was 21.4% (95%CI 18.4-24.3), being higher among women (mean=23.7%, 95%CI 20.4-27.1) than men (mean=18.9%, 95%CI 16.2-21.7). It ranged from 2.6% (in Comoros) to 62.3% (in Mauritania), with a median equal to 18%. After weighting for the total population of each country, the worldwide prevalence of physical inactivity was 17.4% (95%CI 15.1-19.7). There was a positive association between HDI and prevalence of physical inactivity (rho=0.27). Less developed countries showed the lowest prevalence of physical inactivity (18.7%), while physical inactivity was more prevalent among the most developed countries (27.8%).
One out of five adults around the world is physically inactive. Physical inactivity was more prevalent among wealthier and urban countries, and among women and elderly individuals.
描述全球范围内缺乏身体活动的流行情况，并分析其与各国发展水平的关系。
对 2002 年至 2004 年间进行的三项多中心研究进行汇总分析，这些研究调查了 76 个国家的缺乏身体活动的流行情况，共有近 30 万名 15 岁及以上的个体参与。每个研究都使用国际身体活动问卷评估身体活动。各国的发展水平通过人类发展指数（HDI）进行分析。
全球缺乏身体活动的粗患病率为 21.4%（95%置信区间 18.4-24.3），女性（均值 23.7%，95%置信区间 20.4-27.1）高于男性（均值 18.9%，95%置信区间 16.2-21.7）。范围从 2.6%（科摩罗）到 62.3%（毛里塔尼亚），中位数为 18%。对每个国家的总人口进行加权后，全球缺乏身体活动的患病率为 17.4%（95%置信区间 15.1-19.7）。HDI 与缺乏身体活动的患病率之间呈正相关（rho=0.27）。欠发达国家的缺乏身体活动患病率最低（18.7%），而最发达国家的缺乏身体活动患病率最高（27.8%）。
全世界有五分之一的成年人缺乏身体活动。在较富裕和城市国家、女性和老年人中，缺乏身体活动更为普遍。
