This study explored the association between occupational categories and muscle strength using handgrip strength (HGS) while considering sociodemographic and health-related factors in Korean men using a national survey.
Using cross-sectional data of 8380 men (59.9 ± 16.6 years of age), the occupational categories held the longest duration and HGS levels (normal vs. weak) were determined. Logistic regression was applied with adjustment for sociodemographic factors, work-related factors (working hours and schedule), and health-related factors (physical activity, sedentary time, resistance exercise, alcohol consumption, smoking status, chronic illness, subjective health status, weight category, metabolic syndrome, and protein intake).
Weak HGS prevalence was lowest in male managerial or professional workers (1.5%) and highest in male skilled agricultural, forestry, fishery, or craft and the related trades workers (16.4%). Compared to male managerial or professional workers, the odds for weak HGS increased in male service/sales workers (OR 2.41; 95% CI 1.45-3.99) and male manual workers [agricultural/forestry/fishery/craft and related trades workers, OR 2.94 (95% CI 1.78-4.83); equipment/machine operating/assembling workers, OR 1.68 (95% CI 1.05-2.71); and elementary workers, OR 3.43 (95% CI 1.95-6.05)] in the fully adjusted model. Regardless of age groups, income, working hours, strength exercise, and sedentary time levels, and chronic illness and metabolic syndrome status, male manual workers were more likely to have weak HGS compared to male non-manual workers.
Male manual workers may have a higher risk for weak muscle strength compared to male non-manual workers regardless of sociodemographic, work-related, and health-related factors.
本研究使用全国性调查，在考虑社会人口学和健康相关因素的情况下，使用握力（HGS）探讨职业类别与肌肉力量之间的关系。
使用 8380 名男性（59.9±16.6 岁）的横断面数据，确定了职业类别和 HGS 水平（正常与弱）。应用逻辑回归，调整了社会人口学因素、工作相关因素（工作时间和轮班）以及健康相关因素（体力活动、久坐时间、阻力运动、饮酒、吸烟状况、慢性疾病、主观健康状况、体重类别、代谢综合征和蛋白质摄入）。
弱 HGS 的患病率在男性管理或专业人员中最低（1.5%），在男性熟练农业、林业、渔业或手工艺及相关行业工人中最高（16.4%）。与男性管理或专业人员相比，男性服务/销售人员（OR 2.41；95%CI 1.45-3.99）和男性体力劳动者（农业/林业/渔业/手工艺及相关行业工人，OR 2.94；95%CI 1.78-4.83；设备/机器操作/装配工人，OR 1.68；95%CI 1.05-2.71；初级工人，OR 3.43；95%CI 1.95-6.05）的弱 HGS 可能性增加。在完全调整模型中，无论年龄组、收入、工作时间、力量锻炼和久坐时间水平以及慢性疾病和代谢综合征状况如何，男性体力劳动者的弱 HGS 发生风险均高于男性非体力劳动者。
无论社会人口学、工作相关和健康相关因素如何，男性体力劳动者的肌肉力量较弱的风险可能高于男性非体力劳动者。
