目的：本研究目的為調查於職業工會加保之南部泥水業勞工的工作能力和相關因素。

方法：本研究為橫斷式研究設計。研究對象為年滿20歲、識字且可使用國台語溝通，參加講座的南部泥水業職業工會會員，利用不記名自填結構式問卷進行資料蒐集。

結果：本研究結果共282名參與研究(參與率69.8%)。對象主要為男性、已婚、高中/職(含)以下教育程度、50歲以下、平均月薪3萬元以上、非管理職和總工作年資長於15年。整體泥水業勞工工作能力等級大多為「良」。男性、薪資較低、罹患肌肉骨骼傷病、工時較長和年齡較長為工作能力低的相關因素。

結論：泥水業勞工工作能力大多可勝任現有工作，建議未來政府可加強對此類自營作業或無一定雇主的勞工，提供教育或作業輔助設備等宣導或資源，對影響工作能力的因素實施相對應的職場健康促進活動，以維持或提升勞工的健康和工作能力。

Objectives: The purpose of the study is to survey the work ability and related factors among cement workers in Southern Taiwan.

Methods: This is a cross-sectional study design. We recruited workers with at least 20 years old, speaking Mandarin or Taiwanese in seminars. An anonymous self-administered structured questionnaire was used to collect data.

Results: 282 workers participated in the study (participation rate 69.8%). Most respondents were male, married, lower educational level, younger than 50 years of age and having average salary NT$30,000 per month. About half of workers’ degree of work ability was "good". Male gender, earning lower income, having musculoskeletal disorders, longer working hours and elder age were found to be significant factors associated with low work ability.

Conclusions: The result of the study showed that most of the cement workers assess their own work ability was good or excellent. We suggest that the competent authority shall provide relevant education or resources of health management and health promotion activities for workers to promote the health and work ability of cement workers, especially for factors associated with lower work ability.
