目的了解肌肉骨骼疾患(MSDs)在蔬菜大棚作业人员中的分布特征和影响因素。方法于2014年在山东省寿光市5个主要蔬菜种植区抽取15个村1 780名蔬菜大棚作业者,运用改良调查问卷进行调查。分别采用χ2检验和多因素logistic回归分析比较不同属性大棚作业者MSDs发生情况和影响因素。结果 MSDs患病率为78.4﹪(1 395/1 780),身体各部位MSDs患病率居前5位的分别为下背、膝、颈、肩和上背,患病率分别为62.4%、41.9%、22.9%、20.3%和8.4%。χ2检验发现有36个因素与MSDs的发生有关。多因素logistic回归分析发现女性、年龄≥50岁、从事大棚种植工作的年数≥20 a、每天工作≥10 h、5 kg<工作中经常推拉用力<20 kg、经常以不舒服的体位搬举重物、经常稍微弯腰、长时间保持颈部后仰姿势8个因素为大棚作业人员MSDs危险因素;工作中经常使用振动工具为大棚作业人员MSDs保护因素。结论蔬菜大棚作业人员MSDs患病率较高,日常工作中要注意休息缓解。 Objective To understand the distribution characteristics and influencing factors of musculoskeletal disorders (MSDs) in greenhouse workers. Methods A total of 1 780 greenhouses in 15 villages were sampled from 5 major vegetable growing areas in Shouguang City, Shandong Province in 2014 and investigated with a modified questionnaire. Chi-square test and multivariate logistic regression analysis were used to compare the incidence and influential factors of MSDs in different greenhouse operators. Results The prevalence of MSDs was 78.4% (1 395/1 780). The top five MSDs in the body were lower back, knee, neck, shoulder and upper back respectively, with prevalences of 62.4% 41.9%, 22.9%, 20.3% and 8.4%. χ2 test found that there are 36 factors associated with the occurrence of MSDs. Multivariate logistic regression analysis found that females, aged ≥50 years old, engaged in the greenhouse planting work of the number of years ≥ 20 a, daily work ≥ 10 h, 5 kg
