The association of skin color with coronary heart disease risk factors was studied in 4,000 urban Puerto Rican men. Skin color on the inner upper arm was classified according to the von Luschan color tiles. Using this grading, men were separated into two groups of light or dark skin color. The dark group had a lower socioeconomic status (SES) based on income, education, and occupation. Dark men had slightly higher mean systolic blood pressures (SBP) and lower mean serum cholesterol levels than the light, but the relative weights and cigarette smoking habits of both groups were similar. After controlling for the differences in SES, skin color showed a small but statistically significant association with SBP. Whether this association with skin color represents genetic or environmental influences on SBP could not be determined from this study.
在4000名波多黎各城市男性中研究了肤色与冠心病危险因素之间的关联。根据冯·卢尚肤色瓷砖对上臂内侧的肤色进行分类。利用这种分级,将男性分为肤色浅或深的两组。根据收入、教育程度和职业,肤色深的组社会经济地位较低。肤色深的男性平均收缩压(SBP)略高于肤色浅的男性,平均血清胆固醇水平略低于肤色浅的男性,但两组的相对体重和吸烟习惯相似。在控制了社会经济地位的差异后,肤色与收缩压之间存在微小但具有统计学意义的关联。这项研究无法确定这种与肤色的关联是代表对收缩压的遗传影响还是环境影响。
