This study evaluated the prevalence of self-reported musculoskeletal disorders (MSDs) among white-collar workers and investigated their associations with physical activity (PA) levels, time spent sitting, sleep duration, and BMI.
The study included 440 white-collar workers (355 female and 85 male) aged 20-64 years, from randomly selected public institutions, companies, and corporations in the Upper Silesia region, Poland. Participants completed the Nordic Musculoskeletal Questionnaire and the Seven-Day Physical Activity Recall. Statistical analysis included comparisons of PA between workers with and without MSDs and between genders, correlations between MSDs, PA, and sleep duration, and logistic regression assessing associations between potential predictors and MSD presence. Independent variables included age, BMI, daily and occupational sitting time, sleep duration, and PA.
The 12-month prevalence of MSDs was highest for lower back pain (65.9%), neck pain (59.8%), and upper back pain (43.9%), with a similar pattern observed over 7 days. Workers reporting neck pain over the past 12 months engaged in significantly less vigorous PA and high vigorous PA compared to those without neck pain ( = 0.019, = 0.11), while those with knee pain reported higher levels of moderate PA ( = 0.018, = 0.11). Age and BMI significantly influenced pain in multiple regions, including the neck, shoulder, back, hip/thigh, knee, and ankle/foot. Daily sitting time was a significant predictor for most MSDs, except for hip pain, while sitting during work specifically predicted lower back pain over 12 months. Each additional year of age, unit increase in BMI, and hour of sitting increased the likelihood of pain. Sleep duration and PA levels were not significant predictors.
These findings emphasize the importance of BMI management and reducing prolonged sitting as key workplace interventions, particularly in sedentary occupations.
本研究评估了白领中自我报告的肌肉骨骼疾病（MSD）的患病率，并调查了它们与身体活动（PA）水平、久坐时间、睡眠时间和体重指数（BMI）之间的关联。
该研究纳入了440名年龄在20 - 64岁的白领（355名女性和85名男性），他们来自波兰上西里西亚地区随机选取的公共机构、公司和企业。参与者完成了北欧肌肉骨骼问卷和七天身体活动回忆。统计分析包括比较有和没有MSD的工人之间以及不同性别之间的PA，MSD、PA和睡眠时间之间的相关性，以及评估潜在预测因素与MSD存在之间关联的逻辑回归。自变量包括年龄、BMI、每日和工作时的久坐时间、睡眠时间和PA。
MSD的12个月患病率以下背痛（65.9%）、颈部疼痛（59.8%）和上背痛（43.9%）最高，7天内观察到类似模式。与没有颈部疼痛的人相比，在过去12个月报告有颈部疼痛的工人进行的剧烈PA和高强度剧烈PA明显更少（P = 0.019，P = 0.11），而有膝盖疼痛的人报告的中度PA水平更高（P = 0.018，P = 0.11）。年龄和BMI对多个部位的疼痛有显著影响，包括颈部、肩部、背部、臀部/大腿、膝盖和脚踝/足部。每日久坐时间是大多数MSD的显著预测因素，但髋部疼痛除外，而工作时久坐尤其预测了12个月内的下背痛。年龄每增加一岁、BMI每增加一个单位以及久坐时间每增加一小时，疼痛的可能性就增加。睡眠时间和PA水平不是显著的预测因素。
这些发现强调了BMI管理和减少长时间久坐作为关键工作场所干预措施的重要性，特别是在久坐职业中。
