The purpose of this study was to analyze the transition of body mass index (BMI) by birth cohort and to determine the relationship between BMI and high blood pressure, for the health management of workers in an industry.
The eligible study subjects were 3,043 male workers at printing and papermaking plants who were 20 to 49 years of age in 1986 and whose annual health checkup information was available for both 1991 and 1996. First, we analyzed the transition of BMI by 5-year birth cohort. Second, we analyzed the relationship between BMI and high blood pressure (systolic blood pressure > = 140 mmHg or diastolic blood pressure > = 90 mmHg) using multiple logistic regression models. In this analysis, we excluded 596 subjects who were diagnosed as having high blood pressure in 1986 and 17 subjects whose alcohol drinking habits were unknown. Consequently, we had 2,430 study subjects.
(1) All the birth cohorts showed that the proportion of obese subjects (BMI > = 26.4) became higher as age advanced. The proportion was higher for younger cohort. (2) By multiple logistic regression models, age at the beginning of the study, BMI, change of BMI in 5 or 10 years, and alcohol drinking habits were related to the risk of having high blood pressure.
In the health management of workers, it is necessary to evaluate the risk by birth cohort. Also, we consider that we need to initiate obesity counseling before the workers become 30 years of age.
本研究旨在分析按出生队列划分的体重指数（BMI）变化情况，并确定BMI与高血压之间的关系，以便对某行业工人进行健康管理。
符合条件的研究对象为1986年年龄在20至49岁之间、就职于印刷和造纸厂的3043名男性工人，且可获取其1991年和1996年的年度健康检查信息。首先，我们按5年出生队列分析了BMI的变化情况。其次，我们使用多元逻辑回归模型分析了BMI与高血压（收缩压>=140 mmHg或舒张压>=90 mmHg）之间的关系。在该分析中，我们排除了1986年被诊断为患有高血压的596名研究对象以及饮酒习惯不明的17名研究对象。最终，我们得到2430名研究对象。
（1）所有出生队列均显示，肥胖（BMI>=26.4）对象的比例随年龄增长而升高。较年轻队列的该比例更高。（2）通过多元逻辑回归模型可知，研究开始时的年龄、BMI、5年或10年内BMI的变化以及饮酒习惯与患高血压的风险相关。
在工人的健康管理中，有必要按出生队列评估风险。此外，我们认为有必要在工人30岁之前开展肥胖咨询。
