The aim was to evaluate the changes in the prevalence of physical inactivity in the Brazilian adults from 2009-2017.
This study used a time-series research design based on the cross-sectional data of 462,498 Brazilian adults from 2009-2017. Participants were classified as physically inactive if they indicated not participating in physical activity in the last three months. The Prais-Winsten regression analyzed physical inactivity trends over time.
The overall prevalence of physical inactivity was stable (p>0.05). Physical inactivity increased for women in four state capitals (annual growth rate: Goiânia 1.62%, Campo Grande 3.28%, Porto Velho 0.93%, and Vitória 2.09%) and decreased in one (annual growth rate: Rio Branco 4.50%). Physical inactivity decreased for men in four state capitals (annual growth rate: Campo Grande 4.72%, Natal 2.73%, São Luís 4.94%, and Rio Branco 2.95%).
The physical inactivity among the Brazilian adults was stable between 2009 and 2017. Physical inactivity increased in women from Goiânia, Campo Grande, Porto Velho, and Vitória and decreased in women from Rio Branco and in men from Campo Grande, Natal, São Luís, and Rio Branco.
评估 2009-2017 年巴西成年人身体活动不足患病率的变化。
本研究采用时间序列研究设计，基于 2009-2017 年 462498 名巴西成年人的横断面数据。如果参与者表示在过去三个月内没有参加体育活动，则将其归类为身体活动不足。采用普赖斯-温斯坦（Prais-Winsten）回归分析身体活动不足随时间的趋势。
身体活动不足的总体患病率保持稳定（p>0.05）。在四个州首府，女性的身体活动不足增加（年增长率：戈亚尼亚 1.62%、坎波格兰德 3.28%、波多韦柳 0.93%和维多利亚 2.09%），而在一个州首府（年增长率：里奥布兰科 4.50%）减少。在四个州首府，男性的身体活动不足减少（年增长率：坎波格兰德 4.72%、纳塔尔 2.73%、圣路易斯 4.94%和里奥布兰科 2.95%）。
2009 年至 2017 年间，巴西成年人的身体活动不足率保持稳定。戈亚尼亚、坎波格兰德、波多韦柳和维多利亚的女性身体活动不足增加，里奥布兰科的女性和坎波格兰德、纳塔尔、圣路易斯和里奥布兰科的男性身体活动不足减少。
