Excessive sitting behavior is a risk factor for many adverse health outcomes. This study aimed to survey the prevalence of sitting behavior and its adverse effects among Iranian office workers.
This cross-sectional study included 447 Iranian office workers. A two-part questionnaire was used as the data collection tool. The first part surveyed the demographic characteristics and general health of the respondents, while the second part contained the Nordic Musculoskeletal Questionnaire (NMQ) to assess symptoms. Statistical analyses were performed using the Statistical Package for the Social Sciences software using Mann-Whitney U and Chi-square tests and multiple logistic regression analysis.
The respondents spent an average of 6.29 hours of an 8-hour working shift in a sitting position. The results showed that 48.8% of the participants did not feel comfortable with their workstations and 73.6% felt exhausted during the workday. Additionally, 6.3% suffered from hypertension, and 11.2% of them reported hyperlipidemia. The results of the NMQ showed that neck (53.5%), lower back (53.2%) and shoulder (51.6%) symptoms were the most prevalent problem among office workers. Based upon a multiple logistic regression, only sex had a significant association with prolonged sitting behavior (odds ratio = 3.084). Our results indicated that long sitting times were associated with exhaustion during the working day, decreased job satisfaction, hypertension, and musculoskeletal disorder symptoms in the shoulders, lower back, thighs, and knees of office workers.
Sitting behavior had adverse effects on office workers. Active workstations are therefore recommended to improve working conditions.
久坐行为是许多不良健康后果的风险因素。本研究旨在调查伊朗上班族久坐行为的患病率及其不良影响。
这项横断面研究纳入了447名伊朗上班族。使用一份分为两部分的问卷作为数据收集工具。第一部分调查了受访者的人口统计学特征和总体健康状况，而第二部分包含北欧肌肉骨骼问卷（NMQ）以评估症状。使用社会科学统计软件包进行统计分析，采用曼-惠特尼U检验、卡方检验和多元逻辑回归分析。
受访者在8小时工作班次中平均坐着6.29小时。结果显示，48.8%的参与者对其工作站不满意，73.6%的人在工作日感到疲惫。此外，6.3%的人患有高血压，11.2%的人报告患有高脂血症。NMQ的结果显示，颈部（53.5%）、下背部（53.2%）和肩部（51.6%）症状是上班族中最普遍的问题。基于多元逻辑回归，只有性别与久坐行为有显著关联（优势比=3.084）。我们的结果表明，长时间坐着与工作日的疲惫、工作满意度下降、高血压以及上班族肩部、下背部、大腿和膝盖的肌肉骨骼疾病症状有关。
久坐行为对上班族有不良影响。因此，建议使用主动式工作站来改善工作条件。
