项目摘要

This research is composed of three parts : a literature review on work-related factors affecting weight gain and obesity in occupational populations, testing hypotheses that moderate alcohol consumption could suppress the development of metabolic syndrome and that alcohol-induced hypertension is related to increased insulin resistance and metabolic syndrome. The results are summarized as follows.More than 20% of adult Japanese show a body mass index of 25 or more. Obesity is found more in lower social classes, probably due to dissatisfactions with life and work or unhealthy behaviors. Long work, overtime and shift work are related to weight or waist circumference gain. Heavy work load may result in overeating, sedentary, alcohol and cigarette consumption.In middle-aged men and women, there were no differences in the prevalence of IGT and hypertriglyceridemia between nondrinkers, moderate drinkers and excessive drinkers, showing that moderate alcohol consumption does not suppress the development of metabolic syndrome. However, subjects showing elevated scrum GGT showed a higher odds ratio in hypertension, IGT, hypertriglyceridemia and low HDL-cholesterolemia than those with normal serum GGT. Even moderate alcohol consumption will be a risk of metabolic syndrome in sensitive subjects.In middle-aged healthy men, fasting serum insulin showed a decrease with increases in alcohol consumption, while blood glucose was higher in drinkers consuming 60 ml or more of alcohol, resulting lower values of HOMA-IR and HOMA-BC in alcohol consumers. In alcohol consumers, however, higher HOMA-IR was related higher blood pressure, and moderate elevations in serum GGT were related to a high HOMA-IR and the further elevations were related to a low HOMA-BC. These results suggested that high blood pressure in alcohol consumers is related to changes in serum insulin and glucose relationship, and thus increased insulin resistance.

这项研究由三部分组成：对影响职业人群体重增加和肥胖的工作相关因素的文献综述，检验适度饮酒可以抑制代谢综合征的发展以及酒精诱发的高血压与胰岛素抵抗增加有关的假设。和代谢综合征。结果总结如下。超过20%的日本成年人的体重指数为25或更高。肥胖多见于下层社会阶层，可能是由于对生活和工作的不满或不健康的行为所致。长时间工作、加班和轮班工作与体重或腰围增加有关。繁重的工作负荷可能导致暴饮暴食、久坐、酗酒和吸烟。在中年男性和女性中，不饮酒者、适度饮酒者和过量饮酒者之间IGT和高甘油三酯血症的患病率没有差异，表明适量饮酒并不影响IGT和高甘油三酯血症的发生率。抑制代谢综合征的发展。然而，与血清 GGT 正常的受试者相比，血清 GGT 升高的受试者出现高血压、IGT、高甘油三酯血症和低 HDL 胆固醇血症的比值比更高。即使是适量饮酒，对敏感人群也会有患代谢综合征的风险。在中年健康男性中，空腹血清胰岛素随着饮酒量的增加而下降，而饮酒60毫升或更多的饮酒者血糖则较高，导致饮酒者的 HOMA-IR 和 HOMA-BC 值较低。然而，在饮酒者中，较高的 HOMA-IR 与较高的血压相关，血清 GGT 中度升高与高 HOMA-IR 相关，进一步升高与低 HOMA-BC 相关。这些结果表明，饮酒者的高血压与血清胰岛素和血糖关系的变化有关，从而增加了胰岛素抵抗。
