在文化适应人群中，体重一直与血压相关，但在低血压的瘦人群中则不相关。1989年，作者在中国西南部的三个社区随机样本中研究了体重与血压之间的关系：农村彝族农民（5，023名男性，3，218名女性）;彝族移民（1，656名男性，919名女性）;以及生活在城市环境中的汉族人（2，173名男性，1，516名女性）。彝族农民几乎没有肥胖或高血压，血压也几乎没有随年龄增长而上升。彝族移民和汉族随着年龄的增长，血压的斜率更陡，因此高血压更多。对于男性和女性，彝族农民的平均体重指数（体重（kg）/身高（m2））分别为20.6和21.0，彝族移民为21.3和21.4，汉族为21.0和21.4。收缩压和舒张压均与所有六个种族性别组的体重指数呈正相关，在调整年龄、心率、吸烟、饮酒和体力活动后，这种相关性仍具有统计学意义。体重指数每增加1 kg/m2，平均血压的变化，在调整居住社区后，收缩压为1.47 mmHg，舒张压为1.13 mmHg。体重指数和血压之间的关联在男性中大于女性，在彝族移民和汉族中大于彝族农民。彝族农民、彝族流动人口和汉族中因超重（体重指数≥ 25）而患高血压的比例，男性分别为4.1%、34.1%和24.0%，女性分别为0%、26.2%和28.9%。因此，即使在这个平均血压较低的偏瘦中国人群中，体重也与血压升高呈正相关且独立。
Body mass has been consistently associated with blood pressure in acculturated populations but not in lean populations with low blood pressures. In southwestern China, in 1989, the authors studied the relation between body mass and blood pressure in three community-based random samples: rural Yi farmers (5,023 men, 3,218 women); Yi migrants (1,656 men, 919 women); and Han Chinese living in an urban setting (2,173 men, 1,516 women). The Yi farmers had virtually no obesity or hypertension and had little rise in blood pressure with age. The Yi migrants and Han had a steeper slope of blood pressure with age and consequently more hypertension. For men and women, respectively, mean body mass index (weight (kg)/height (m)(2)) was 20.6 and 21.0 in the Yi farmers, 21.3 and 21.4 in the Yi migrants, and 21.0 and 21.4 in the Han. Both systolic and diastolic blood pressure were positively related to body mass index in all six ethnicity-sex groups, and the association remained statistically significant after adjustment for age, heart rate, smoking, alcohol intake, and physical activity. The change in mean blood pressure for each kg/m(2) increase in body mass index, after adjustment for community of residence, was 1.47 mmHg for systolic pressure and 1.13 mmHg for diastolic pressure. The association between body mass index and blood pressure was greater in men than in women and greater in Yi migrants and Han than in Yi farmers. The percentages of hypertension attributable to overweight (body mass index greater than or equal to 25) among the Yi farmers, Yi migrants, and Han, respectively, were 4.1%, 34.1%, and 24.0% for men and 0%, 26.2%, and 28.9% for women. Thus, even in this lean Chinese population with a low mean blood pressure, body mass was positively and independently associated with increased blood pressure.
