| 摘要: | 研究目的：針對某液晶顯示器玻璃基板廠員工之健康檢查結果進行分析，探討特定工作型態：如輪班工作、延遲下班與代謝症候群的相關性。
研究方法：本研究是橫斷面研究設計。研究對象是民國97年某液晶顯示器玻璃基板廠參加年度定期健康檢查的勞工，利用結構式自填問卷調查研究個案特定工作型態：輪班狀況、延遲下班情形等工作情形、基本人口學資料、個人病史、家族病史、健康行為、個人心理狀態。健康檢查項目則包含代謝症候群定義項目，包括腰圍、血壓、血糖、血脂肪之空腹檢查結果。統計方法以卡方檢定、費雪正確性檢定、獨立樣本t檢定進行單變項分析，以羅吉斯迴歸分析探討特定工作型態及其它因子與代謝症候群、腹部肥胖、高血壓、高血糖、高密度酯蛋白膽固醇偏低、空腹血糖值偏高、及高三酸甘油酯之相關。
研究結果：有效研究樣本男性佔827人，女性僅85人。平均年齡女性為30.8±4.5歲，男性為31.2±4.0歲。代謝症候群之盛行率結果顯示，全體盛行率為20.8%，女性為8.2%，男性為22.1%。針對女性特定工作型態中以輪班超過1年以上有較強的相關，逐步羅吉斯迴歸分析結果顯示，在調整其它變項的影響後，以輪班超過1年以上較輪班小於1年者，有代謝症候群之勝算比(odds ratio, OR)為4.09 ( 95% 信賴區間 (CI)：0.78-21.49)、有腹部肥胖之OR為3.68 (95% CI：0.99-13.68)、有高血壓之OR為8.56 (95% CI：1.97-37.1)、有空腹血糖值偏高之OR為3.86 (95% CI：0.74-20.09)，此外針對女性，有輪班較沒有輪班者，有腹部肥胖之OR為4.22 (95% CI：1.07-16.61)，達統計上顯著的意義。針對男性特定工作型態中以延遲下班超過1小時以上有較強的相關，以延遲下班超過1小時以上較延遲下班小於1小時者，有代謝症候群之OR為1.51 (95% CI：1.01-2.26)、有腹部肥胖之OR為1.44 (95% CI：0.96-2.14)、有高密度酯蛋白膽固醇偏低之OR為1.37 (95%CI：0.96-1.96)。
結論：本研究顯示輪班超過1年以上是女性有代謝症候群、有腹部肥胖、有高血壓、及有空腹血糖值偏高的較重要危險因子。而延遲下班超過1小時以上則是男性有代謝症候群、有腹部肥胖、及有高密度酯蛋白膽固醇偏低的較重要危險因子。
Objectives: With the aim to investigate the association between certain job types, such as shift work and overtime work, etc. and metabolic syndrome among workers in a liquid crystal display (LCD) glass substrate factory.
Methods: This was a cross-sectional study. The study subjects at a LCD glass substrate factory received the annual health examination in 2008. With a written informed consent, each participant was asked to fill out a standard questionnaire. Information on types of job, such as shift work and overtime work, etc, demographic data, personal medical history, family history, health behavior and psychological factors were collected. The health exam measured waist, blood pressure, blood glucose and lipid profiles. Chi-square test, Fisher’s exact test and independent t-test were used to determine correlations. The multiple logistic regression analysis was used to measure whether the metabolic syndrome was associated with job types, demographic status, personal medical history, family history, health behavior and psychological factors.
Results: We recruited 827 male workers and 85 female workers with the mean ages of 30.8 (±4.5) years in females and 31.2 (±4.0) years in males. The prevalence rates of metabolic syndrome were 20.8% in all study subjects, 8.2% in female workers, 22.1% in male workers. Compare to female workers on shift work < 1 year, those on shift work ≧ 1 year were more likely to have metabolic syndrome (adjusted odds ratio (aOR)= 4.09, 95% confendence interval (CI)：0.78-21.49), central obesity (aOR=3.68, 95% CI：0.99-13.68), high blood pressure (aOR =8.56, 95% CI：1.97-37.14) and high fasting glucose (aOR =3.68, 95% CI：0.74-20.09). Compared to those who were never on shift work, the risk of central obesity increased slightly for those on shift work (aOR=4.22, 95% CI：1.07-16.61). Compared to male workers with the average work-overtime < 1 hour, those having average work-overtime ≧ 1 hour were more likely to have metabolic syndrome ( aOR=1.51, 95% CI：1.01-2.26), central obesity ( aOR=1.44, 95% CI：0.96-2.14) and low HDL-cholesterol ( aOR=1.37, 95% CI：0.96-1.96).
Conclusion: Female workers with shift work ≧1 year were at elevated risk of metabolic syndrome, central obesity, high blood pressure and high fasting glucose. Male workers with the average work-overtime ≧ 1hour were at higher risk of metabolic syndrome, central obesity and low HDL-cholesterol. |
