BACKGROUND
Abdominal fat distribution varies across groups with different races or environments. Whether environmental factors, apart from racial differences, affect abdominal fat distribution is unknown.
METHODS
We compared the abdominal fat distribution of four groups; different races with similar environments (Caucasians vs. Japanese Americans), different environments with an identical race (Japanese Americans vs. Japanese), and similar races with similar environments (Japanese vs. Koreans). A population-based sample of 1212 men aged 40-49 were analyzed: 307 Caucasians and 300 Japanese Americans in the United States, 310 Japanese in Japan, and 295 Koreans in Korea. We compared the proportion of visceral adipose tissue area to total abdominal adipose tissue area (VAT%) and other factors that can affect abdominal fat distribution (smoking, alcohol use, physical activity levels, and metabolic factors).
RESULTS
VAT% was significantly higher in Japanese and Koreans than in Japanese Americans and Caucasians (50.0, 48.5, 43.2, 41.0%, respectively, P < 0.001). Even after adjustment for possible confounders, the significant VAT% difference remained in comparing groups with identical race but different environments (i.e., Japanese vs. Japanese Americans). In contrast, comparing groups with different races but similar environments (i.e., Caucasians vs. Japanese Americans), VAT% was not significantly different. Comparing groups with similar races and similar environments (i.e., Japanese vs. Koreans), VAT% did not significantly differ.
CONCLUSIONS
Environmental differences, apart from racial differences, affect the difference in abdominal fat distribution across different groups in middle-aged men.
背景
腹部脂肪分布在不同种族或环境的人群中存在差异。除种族差异外，环境因素是否会影响腹部脂肪分布尚不清楚。
方法
我们比较了四组人群的腹部脂肪分布情况：环境相似的不同种族（白种人与日裔美国人）、种族相同但环境不同的人群（日裔美国人与日本人）以及环境相似的相近种族（日本人与韩国人）。对1212名年龄在40 - 49岁的男性进行了基于人群的样本分析：美国的307名白种人和300名日裔美国人、日本的310名日本人以及韩国的295名韩国人。我们比较了内脏脂肪组织面积占腹部总脂肪组织面积的比例（VAT%）以及其他可能影响腹部脂肪分布的因素（吸烟、饮酒、身体活动水平和代谢因素）。
结果
日本人及韩国人的VAT%显著高于日裔美国人和白种人（分别为50.0%、48.5%、43.2%、41.0%，P < 0.001）。即使对可能的混杂因素进行调整后，在比较种族相同但环境不同的组（即日本人与日裔美国人）时，VAT%的显著差异仍然存在。相比之下，在比较种族不同但环境相似的组（即白种人与日裔美国人）时，VAT%没有显著差异。在比较种族相近且环境相似的组（即日本人与韩国人）时，VAT%也没有显著差异。
结论
除种族差异外，环境差异会影响中年男性不同群体间腹部脂肪分布的差异。
