This study's main objective was to investigate the emergence of back pain as a consequence to changes in usual activities due to the COVID-19 pandemic among teachers in public schools in the state of Minas Gerais, Brazil.
A cross-sectional study was conducted among 15,276 schoolteachers using an online questionnaire. The variables included sociodemographic and occupational data, health situation, habits and behaviors during the COVID-19 pandemic. Bivariate analyses using Pearson's chi-square test and multiple analyses using Poisson regression were performed to identify the associated factors.
About 58% of schoolteachers reported back pain due to changes in routine activities during the pandemic. The adjusted model showed a correlation between back pain and female sex, longer working hours, overwork, difficulties concerning distance working, negative changes in health status and quality of sleep; frequent feeling of sadness, depression, or anxiety; use of medications to relax, sleep or against stress/anxiety/depression; physical inactivity or negative changes in the practice of physical activities; increased body weight; reduction of leisure time; increased time of use of computer or tablet and overload of housework.
During the COVID-19 pandemic, schoolteachers reported a high prevalence of emergence of back pain, which delineates a contradiction in terms: on the one hand, distance education allows social distancing that contributes to the preservation of teachers' health by reducing the risk of contamination by COVID-19. On the other hand, it imposes new demands that-in disagreement with working conditions-can threaten the health of these workers.
本研究的主要目的是调查巴西米纳斯吉拉斯州公立学校教师因 COVID-19 大流行而改变日常活动后出现背痛的情况。
采用横断面研究方法，使用在线问卷对 15276 名学校教师进行调查。变量包括社会人口学和职业数据、健康状况、COVID-19 大流行期间的习惯和行为。采用 Pearson 卡方检验进行二变量分析，采用泊松回归进行多变量分析，以确定相关因素。
约 58%的教师报告因大流行期间日常活动的改变而出现背痛。调整后的模型显示，背痛与女性、工作时间延长、过度劳累、远程工作困难、健康状况和睡眠质量的负面变化、频繁感到悲伤、抑郁或焦虑、使用药物放松、睡眠或缓解压力/焦虑/抑郁、身体活动减少或身体活动习惯的负面变化、体重增加、休闲时间减少、使用电脑或平板电脑时间增加以及家务负担增加有关。
在 COVID-19 大流行期间，教师报告背痛的发生率很高，这描绘了一个矛盾：一方面，远程教育允许社交距离，通过降低 COVID-19 感染的风险，有助于保护教师的健康。另一方面，它提出了新的要求，这些要求与工作条件不符，可能会威胁到这些工人的健康。
