The aims of this paper were to document the body mass index (BMI) and anthropometric characteristics of the city of Harare urban dwellers of Zimbabwe. To investigate the relationship between BMI, sum of skin folds (SSF) and percent body fat (PBF).
Cross sectional study.
Designated fitness awareness locations in the city of Harare during the 1998 physiotherapy awareness week.
The participants were 140 apparently healthy adults, males (n = 71) and females (n = 69).
Body Mass Index.
The minimum and maximum values of BMI were 17.7 and 33.3 for men, 17.6 and 47.8 for women. BMI was not found to increase with aging but PBF on the contrary did. The mean BMI value for the males and females was 24.89 +/- 3.18 and 27.8 +/- 5.89 respectively. There was no significant difference in mean BMI between sexes (p = 0.331). Weight was also similar by gender (p = 0.4691). In both sexes, the BMI showed a significant positive correlation with PBF, SSF, body weight and age (for males r = 0.721, 0.731, 0.900, 0.369, p < 0.01 respectively; and in females r = 0.786, 0.804, 0.940, 0.404 and p < 0.01 respectively).
Women were found to have higher BMI, PBF, SSF than their male counterparts. On the average, men were found to be taller, with no significant difference in weight. There was a linear relationship between BMI and PBF, and all the variables investigated except age and stature in both sexes. Because of the differences of environment and industrialisation, estimation of BMI should involve such factors as ethnicity, race, gender and age.
本文旨在记录津巴布韦哈拉雷市城市居民的体重指数（BMI）和人体测量特征。研究BMI、皮褶厚度总和（SSF）与体脂百分比（PBF）之间的关系。
横断面研究。
1998年物理治疗宣传周期间，在哈拉雷市指定的健身意识宣传地点。
140名明显健康的成年人，男性（n = 71）和女性（n = 69）。
体重指数。
男性BMI的最小值和最大值分别为17.7和33.3，女性为17.6和47.8。未发现BMI随年龄增长而增加，而PBF则相反。男性和女性的平均BMI值分别为24.89±3.18和27.8±5.89。两性之间的平均BMI无显著差异（p = 0.331）。按性别划分的体重也相似（p = 0.4691）。在两性中，BMI与PBF、SSF、体重和年龄均呈显著正相关（男性r分别为0.721、0.731、0.900、0.369，p均<0.01；女性r分别为0.786、0.804、0.940、0.404，p均<0.01）。
发现女性的BMI、PBF和SSF高于男性。平均而言，男性更高，体重无显著差异。BMI与PBF之间存在线性关系，且在两性中除年龄和身高外的所有研究变量之间均存在线性关系。由于环境和工业化的差异，BMI的估计应考虑种族、民族、性别和年龄等因素。
