Combined with insufficient physical activity (PA) prolonged and improperly performed sedentary work can lead to musculoskeletal disorders (MSDs). The aim of this study was (I) to evaluate the self-reported level of PA and the prevalence of MSDs in male and female teachers, and (II) to investigate the association between PA and MSDs in teachers in Polish primary and secondary schools.
The study included 254 teachers from primary and secondary schools from Upper Silesia, Poland, excluding physical education teachers. The level of PA was assessed using the Seven-Day Physical Activity Recall (SDPAR). A standardized Nordic Musculoskeletal Questionnaire (NMQ) was used to assess the prevalence of MSDs.
A similar percentage of female (80%) and male (90%) teachers met the WHO recommendations on moderate-intensity PA. The recommendations on performing vigorous-intensity PA were met by significantly ( = 0.002) less female than male teachers (50% and 75% respectively). Lower back disorders during the last 12 months and the last 7 days (57% and 45%, respectively) were the most commonly reported MSDs by teachers, followed by neck (53%, 40%), upper back (39%, 28%), and knee disorders (37%, 26%). The highest pain intensity was experienced by the teachers in the lower back and neck. Teachers with a greater number of MSDs were less likely to engage in vigorous-intensity PA and total PA than those with fewer painful areas of the body. Pain intensity in the neck, knees, upper- and lower back, and wrists/hands was negatively related to moderate and total PA. BMI negatively correlated with total PA, moderate-intensity PA vigorous-intensity PA, and high vigorous-intensity PA.
The study revealed the association between PA and MSDs in studied teachers. The most of the studied teachers met the WHO recommendation, and women were less likely to perform vigorous and high-vigorous PA than men. The lower back and neck disorders were the most common among the teachers.
结合体力活动不足（PA）和长时间不当的坐姿工作，可能会导致肌肉骨骼疾病（MSD）。本研究的目的是：（一）评估男女性教师的自我报告体力活动水平和 MSDs 的流行率；（二）调查波兰中小学教师体力活动与 MSDs 之间的关系。
本研究纳入了来自波兰上西里西亚地区的 254 名中小学教师（不包括体育教师）。体力活动水平使用 7 天体力活动回忆（SDPAR）进行评估。使用标准化的北欧肌肉骨骼问卷（NMQ）评估 MSDs 的流行率。
相似比例的女教师（80%）和男教师（90%）符合世界卫生组织关于中等强度 PA 的建议。而进行高强度 PA 的建议则分别有显著差异（= 0.002），女教师（50%和 75%）明显少于男教师。在过去 12 个月和过去 7 天中，下背部疾病（分别为 57%和 45%）是教师最常报告的 MSD，其次是颈部（53%，40%）、上背部（39%，28%）和膝盖疾病（37%，26%）。下背部和颈部的疼痛强度最高。有更多 MSD 的教师比有较少身体疼痛区域的教师更不可能进行高强度 PA 和总 PA。颈部、膝盖、上下背部和手腕/手部的疼痛强度与中等强度和总 PA 呈负相关。BMI 与总 PA、中等强度 PA、高强度 PA 和高高强度 PA 呈负相关。
本研究揭示了研究教师中 PA 与 MSDs 之间的关系。大多数研究教师符合世界卫生组织的建议，女性进行高强度和高剧烈 PA 的可能性低于男性。下背部和颈部疾病是教师中最常见的疾病。
