One-third of adults worldwide are physically inactive causing over 5.3 million deaths annually. Despite a growing focus on physical activity and health, population-based data on physical activity trends in low- and middle-income countries are still limited. To help fill the gap, this study provides trend data over a 10-year period in Pelotas, a southern Brazilian city.
The short version of the International Physical Activity Questionnaire was used to assess the prevalence of physical inactivity in 2002 (n = 3119), 2007 (n = 2969), and 2012 (n = 2868). Levels of inactivity and trends were assessed according to sex, age, schooling, and socioeconomic position (SEP).
The prevalence of physical inactivity rose from 41.1% (95% CI: 37.4-44.9) in 2002 and 52.0% (95% CI: 49.1-53.8) in 2007 to 54.4% (95% CI: 51.8-56.9) in 2012 (P < .001). Physical inactivity significantly increased in all subgroups except in the highest SEP and 70+ year age subgroups.
After a sharp increase in the prevalence of physical inactivity from 2002-2007, levels plateaued from 2007-2012. However, it is important to stress that current levels are still unacceptably high, and that efforts must be intensified to reverse the trend.
全球三分之一的成年人缺乏身体活动，每年导致超过530万人死亡。尽管对身体活动与健康的关注日益增加，但关于低收入和中等收入国家身体活动趋势的基于人群的数据仍然有限。为了填补这一空白，本研究提供了巴西南部城市佩洛塔斯10年期间的趋势数据。
采用国际身体活动问卷简版评估2002年（n = 3119）、2007年（n = 2969）和2012年（n = 2868）身体不活动的患病率。根据性别、年龄、受教育程度和社会经济地位（SEP）评估不活动水平和趋势。
身体不活动的患病率从2002年的41.1%（95%CI：37.4 - 44.9）、2007年的52.0%（95%CI：49.1 - 53.8）上升至2012年的54.4%（95%CI：51.8 - 56.9）（P <.001）。除最高SEP和70岁及以上年龄亚组外，所有亚组的身体不活动情况均显著增加。
2002 - 2007年身体不活动患病率急剧上升后，2007 - 2012年水平趋于平稳。然而，必须强调的是，目前的水平仍然高得令人无法接受，必须加大力度扭转这一趋势。
