Quarantine periods change routines and behaviors with potential impact on different health outcomes.
To determine the association between changes in physical activity and sedentary behaviors with changes in back pain during the COVID-19 pandemic quarantine among Brazilian adults.
This was a nationwide survey through online questionnaires using data from 43,062 adults (≥ 18 years of age). Information on back pain was assessed using questions about episodes of back pain and worsening symptoms during the quarantine. The pattern of movement behaviors adopted before and during the pandemic were considered for physical inactivity (< 150 min/week of activity), high TV-viewing (≥ 4 h/d), and high computer/tablet use (≥ 4 h/d). Covariates included sex, age group, academic achievement, skin color, working status during the quarantine, and adherence to the quarantine. Logistic regression models were used for statistical analyses (weighted for national representativity).
Becoming inactive (OR=1.76, 95% CI: 1.32, 2.37), with high TV-viewing (OR=1.35, 95% CI: 1.14, 1.61) and high computer/tablet use (OR=1.39, 95% CI: 1.11, 1.73) during the pandemic were associated with a higher incidence of back pain. The incidence of physical inactivity was also associated with increased back pain (OR=2.71, 95%CI: 1.64, 4.48).
We conclude that increased physical inactivity and sedentary behaviors due to the COVID-19 pandemic quarantine are associated with the incidence and worsening symptoms of back pain among Brazilian adults.
检疫期改变了日常生活习惯和行为，可能对不同的健康结果产生影响。
确定在 COVID-19 大流行检疫期间，巴西成年人的身体活动和久坐行为的变化与背痛变化之间的关系。
这是一项全国性的在线问卷调查研究，共纳入了 43062 名成年人（≥18 岁）。使用关于背痛发作和检疫期间症状恶化的问题来评估背痛信息。在流行前和流行期间采用的运动行为模式被认为是身体活动不足（<150 分钟/周的活动量）、高电视观看（≥4 小时/天）和高电脑/平板电脑使用（≥4 小时/天）。协变量包括性别、年龄组、学历、肤色、检疫期间的工作状态和遵守检疫情况。采用逻辑回归模型进行统计分析（加权以反映全国代表性）。
在流行期间变得不活跃（OR=1.76，95%CI：1.32，2.37）、高电视观看（OR=1.35，95%CI：1.14，1.61）和高电脑/平板电脑使用（OR=1.39，95%CI：1.11，1.73）与背痛的发生率增加相关。在流行期间身体活动不足也与背痛增加相关（OR=2.71，95%CI：1.64，4.48）。
我们得出结论，由于 COVID-19 大流行检疫，身体活动减少和久坐行为的增加与巴西成年人背痛的发生率和症状恶化有关。
