We report analyses of data on body fat from a cohort of 34 separated monozygotic twin pairs (MZA) and a matched sample of 38 pairs of monozygotic twins reared together (MZT) originally studied by James Shields. The correlation for MZA pairs was .61 and the correlation for MZT pairs was .75. These correlations did not differ significantly, nor did correlations differ between MZA pairs subclassified as having been raised in relatively more or less similar environments. Our results suggest important roles for both genes and environment in the accumulation of body fat and support other adoption studies in suggesting that adult environments rather than rearing environments are the most important nongenetic determinants of levels of body fat in adults.
我们报告了对一组34对分开抚养的同卵双胞胎（MZA）以及38对一起抚养的同卵双胞胎（MZT）匹配样本的身体脂肪数据的分析，这些样本最初由詹姆斯·希尔兹进行研究。MZA双胞胎对的相关性为0.61，MZT双胞胎对的相关性为0.75。这些相关性没有显著差异，在分类为在相对更相似或更不相似环境中长大的MZA双胞胎对之间，相关性也没有差异。我们的结果表明，基因和环境在身体脂肪积累中都起着重要作用，并支持其他收养研究，表明成人环境而非成长环境是成年人身体脂肪水平最重要的非遗传决定因素。
