Workers in high technology industry are experiencing stressful environment and have been ranked as a high risk group for adverse health effects. The effectiveness of worksite health promotion is important for occupational health. This study is to investigate the effect of health interventions on body measurement changes while examining the role of their lifestyle factors.
A total of 904 participants aged over 30 years were recruited from 14 semiconductor worksites in Taiwan from 2011 to 2015. A multi-settings, quasi-experimental study was conducted that assigned participants into two intervention programs, including exercise program and diet-plus-exercise program. The outcomes include the changes of body weight, waist circumference, body mass index (BMI), and biophysiological indicators. Lifestyle variables include alcohol consumption, cigarette smoking, and regular exercise. Multiple linear regression analyses were performed to test the association.
The findings have demonstrated that one kilogram body weight reduction is associated with a decrease of 0.58 mmHg SBP (p < 0.001), 0.29 mmHg DBP (p < 0.001), 3.33 mg/dL triglyceride (p < 0.001), 0.96 mg/dL total cholesterol (p < 0.001), and 0.68 mg/dL LDL (p < 0.001). The diet-plus-exercise group had more significant effect on both weight changes and biophysiological changes than exercise-only group (p < 0.001). Lifestyle factors, including cigarette smoking, alcohol consumption, and regular exercise, were significant moderators of the effectiveness of health interventions.
Both exercise and diet interventions are important to the effectiveness of health promotion in occupational sectors. Lifestyle modifications are vital for weight control programs in improving body shape changes and biophysiological indicators.
高科技行业的工人面临着压力环境，已被列为健康不良影响的高风险群体。工作场所健康促进的效果对于职业健康很重要。本研究旨在调查健康干预对身体测量变化的影响，同时检验其生活方式因素的作用。
本研究于 2011 年至 2015 年期间在台湾的 14 个半导体工厂招募了 904 名年龄在 30 岁以上的参与者。进行了一项多环境、准实验研究，将参与者分为两种干预方案，包括运动方案和饮食加运动方案。结果包括体重、腰围、身体质量指数（BMI）和生物生理指标的变化。生活方式变量包括饮酒、吸烟和定期运动。采用多元线性回归分析检验关联。
研究结果表明，体重减轻 1 公斤与收缩压降低 0.58 毫米汞柱（p<0.001）、舒张压降低 0.29 毫米汞柱（p<0.001）、甘油三酯降低 3.33 毫克/分升（p<0.001）、总胆固醇降低 0.96 毫克/分升（p<0.001）和 LDL 降低 0.68 毫克/分升（p<0.001）相关。与仅运动组相比，饮食加运动组对体重变化和生物生理变化的影响更为显著（p<0.001）。生活方式因素，包括吸烟、饮酒和定期运动，是健康干预效果的重要调节剂。
运动和饮食干预对于职业领域的健康促进效果都很重要。生活方式的改变对于体重控制计划至关重要，有助于改善体型变化和生物生理指标。
