Abstract

Descriptive, prospective, transversal and correlational study, whose objective is to relate two formulas for calculating BMI, with other indicators, in a group of adults. METHODS: The sample is of 137 adult patients who attended consultation at the University Hospital of Caracas. The variables are: age, weight, size, BMI-Q, BMI-O, WC, WSI, WCWP and BFP. Averages, deviations, percentages and z-tests and Mann Whitney were obtained to compare averages and Median. RESULTS: Similar BMI-Q averages in both sexes, and older BMI-O in female sex. The two formulas for calculating BMI result in the highest percentage with BMI-O, higher overweight percentage with BMI-Q and significant (p<0.000) and percentages of Healthy Weight and Obesity equal. Equal averages, per group, of BFP for the two BMI formulas, and increase from Healthy Weight to Obesity. The Coefficient of Variation reveals more homogeneity in BMI-O (18.41% vs 25.21%). BMI-Q correlates with weight (0.91), WC (0.92) and WSI (0.93); IMC-O with weight (0.97), WC (0.83) and WCWI (0.90). Whitney's test reveals that averages by sex are significant (p<0,000), as are IPCC averages per sex (p<0.000). In addition, the BMI Oxford, WC, WSI and WCWI indicators have sensitivity of 92,3%, 92.3% and 92.3%, respectively. CONCLUSION: The BMI Oxford for its somewhat complicated calculation formula is not recommended to evaluate overweight and obesity, in adults.

计算成人bmi的两个公式及其与其他人体测量指标的关系

描述性、前瞻性、横向和相关性研究，其目的是在一组成年人中将两个计算BMI的公式与其他指标联系起来。方法:样本为在加拉加斯大学医院就诊的137名成年患者。变量为:年龄、体重、体型、BMI-Q、BMI-O、WC、WSI、WCWP和BFP。获得平均值、偏差、百分比、z检验和Mann Whitney检验来比较平均值和中位数。结果:男女BMI-Q平均值相似，女性BMI-O值较大。两种计算BMI的公式得出BMI- 0的百分比最高，BMI- q的百分比较高，且健康体重和肥胖的百分比相等(p<0.000)。两种BMI公式的每组BFP平均值相等，并且从健康体重增加到肥胖。变异系数显示BMI-O的同质性更强(18.41% vs 25.21%)。BMI-Q与体重(0.91)、WC(0.92)、WSI(0.93)相关;体重的IMC-O(0.97)、WC(0.83)和WCWI(0.90)。Whitney的检验表明，性别的平均值是显著的(p< 0000)， IPCC的性别平均值也是显著的(p<0.000)。BMI Oxford、WC、WSI和WCWI指标的敏感性分别为92%、3%、92.3%和92.3%。结论:牛津体重指数的计算公式有些复杂，不推荐用于评估成人超重和肥胖。
