Abdominal Visceral Fat of Japanese Adult

今年，我们对生活在东京大都市区的同一年龄组的男性和女性与生活在冲绳和北海道的同等年龄组进行了一些比较研究，以调查环境因素是否对内脏脂肪的数量和皮下脂肪的分布有影响。采用氢密度法测量体脂百分比，采用b超法计算皮下脂肪量及其分布，测量皮下脂肪厚度并取体表各节段。内脏脂肪的数量是通过测量总脂肪量和皮下脂肪量的差异来估计的。调查结果显示，冲绳和北海道成年男性和成年女性体内内脏脂肪的百分比和皮下脂肪的分布没有明显差异。这一结果证明，天气（炎热的环境相对于寒冷的环境……更多的环境）对体内内脏脂肪积累的数量几乎没有影响。另一方面，生活在东京市区的成年男女内脏脂肪占全身脂肪的比例远高于冲绳和北海道的同龄人。很明显，城市环境是内脏脂肪积累的一个影响因素。同样在今年进行的另一项研究是关于有氧运动训练对减少内脏脂肪量的影响。几个肥胖的研究对象被挑选出来进行为期13周的有氧运动训练，以观察它在减少体脂、内脏脂肪和皮下脂肪方面的效果。结果表明，有氧运动对内脏脂肪的减少没有明显的效果，但对皮下脂肪的减少却有明显的效果。通过体育锻炼可以减少皮下脂肪，但有氧运动训练对内脏脂肪没有直接影响。13EA07：此外，对身体脂肪分布和内脏脂肪量与个人饮食习惯和生活方式的关系进行的调查结果表明，酒精和糖的摄入量显然是导致内脏脂肪量增加的主要因素。少

This year, we have conducted some comparative studies of male and female in the same age group, living in the Tokyo metropolitan area with equivalent groups living in Okinawa and Hokkaido to investigate whether environmental factors have affects on the amount of visceral fat and distribution of subcutaneous fat.The percentage of body fat was measured by the Hydrodensitometry method and the amount of subcutaneous fat and its distribution was computed by B-mode Ultrasound method, measuring the thickness of subcutaneous fat and taking each segment from body surface area.The amount of visceral fat was then estimated by the measured difference in the amount of total body fat and subcutaneous fat. The results of this investigation showed that there were no noticeable differences in the percentage of visceral fat and distribution of subcutaneous fat contain in the body between mature male and female adults in Okinawa and Hokkaido. This results proved that the weather(hot opposed to cold envir … More onment)have little or no affect on the amount of visceral fat accumulated in the body.On the other hand, the percentage of visceral fat versus the amount of total body fat in mature male and female adults living in the Tokyo metropolitan area was much higher than their counterparts in Okinawa and Hokkaido. It was apparent that the city environment was an influential factor in the accumulation of visceral fat.Also conducted this year, was another study on the effect aerobic exercise training has in reducing the amount of visceral fat. Several obese subject were selected to conduct a 13-week aerobic exercise training program to see what effect it would have in reducing the amount of body fat, visceral fat, and subcutaneous fat.The results showed that there was no apparent effect of aerobic exercise reducing the amount of visceral fat, however there was a noticeable reduction of subcutaneous fat. Subcutaneous fat was reduced through physical exercise, but visceral fat was no directly affected by aerobic exercise training.13EA07 : Furthermore, as a results of investigation done on the relationship of body fat distribution and amount of visceral fat to individual eating habits and life-styles, it was apparent that the amount of alcohol and sugar intake was the primary factor contributing to the increase in the amount of visceral fat.
