The purpose of this study was to examine the effects of smoking cessation on body mass index (BMI), blood pressure and serum lipids in middle-aged male workers considering the effect of BMI which would increase by smoking cessation. The subjects were 1431 middle-aged men who worked in an enterprise in Hiroshima prefecture. Cross-sectional data measured in 1989 and longitudinal data measured from 1985 to 1989 were used in this analysis. The effect of smoking cessation on BMI, blood pressure and serum lipids were evaluated by two models of analysis of covariance (PC-SAS: GLM procedure) for the cross-sectional data and longitudinal data. In analysis of the cross-sectional data, model 1 was controlled for BMI and model 2 was not controlled for BMI. In analysis of the longitudinal data, model 3 was controlled for BMI change and model 4 was not controlled for BMI change. The main results are summarized as follows: 1. BMI was increased over the short period by smoking cessation, but over the long period BMI of ex-smokers remained at almost the same level as non-smokers'. 2. Blood pressure was increased over the short period by both the effect of smoking cessation and BMI increase from abstention from smoking. But over the long period blood pressure of ex-smokers remained at almost the same level as non-smokers. 3. Triglycerides (TG) and atherogenic index (AI) tended to decrease and HDL-cholesterol (HDLC) tended to increase over the short period by smoking cessation, but the concomitant BMI increase may have blunted any independent beneficial effect of smoking cessation on TG, AI and HDLC. But over the long period TG, AI and HDLC of ex-smokers recovered to almost the same level as non-smokers', and remained at that level. 4. These results suggest that smoking cessation have beneficial effects for health promotion in middle-aged men.
本研究的目的是，鉴于戒烟会使体重指数（BMI）升高，探讨戒烟对中年男性工人的体重指数、血压和血脂的影响。研究对象为1431名在广岛县一家企业工作的中年男性。本分析使用了1989年测量的横断面数据以及1985年至1989年测量的纵向数据。通过协方差分析的两种模型（PC-SAS：GLM过程）对横断面数据和纵向数据进行分析，以评估戒烟对BMI、血压和血脂的影响。在横断面数据分析中，模型1对BMI进行了控制，模型2未对BMI进行控制。在纵向数据分析中，模型3对BMI变化进行了控制，模型4未对BMI变化进行控制。主要结果总结如下：1. 短期内，戒烟会使BMI升高，但长期来看，戒烟者的BMI与非吸烟者几乎保持在同一水平。2. 短期内，戒烟的影响以及因戒烟导致的BMI升高都会使血压升高。但长期来看，戒烟者的血压与非吸烟者几乎保持在同一水平。3. 短期内，戒烟会使甘油三酯（TG）和致动脉粥样硬化指数（AI）趋于降低，高密度脂蛋白胆固醇（HDLC）趋于升高，但同时BMI的升高可能削弱了戒烟对TG、AI和HDLC的任何独立有益作用。但长期来看，戒烟者的TG、AI和HDLC恢复到与非吸烟者几乎相同的水平，并保持在该水平。4. 这些结果表明，戒烟对中年男性的健康促进有有益影响。
