UNLABELLED
To assess the accuracy of BMI compared to directly measured dual-energy X-ray absorptiometry percent body fat (DEXA %BF) among a worker compensation population.
METHODS
The agreement between BMI and DEXA %BF was assessed by the Pearson correlation coefficient among 1394 evaluable patients over a 5-year period. Sensitivity and specificity were calculated to measure how well BMI can identify true obese and nonobese individuals.
RESULTS
Using at least 30kg/m to identify obesity, BNI had a specificity of 0.658 and a sensitivity of 0.735. The correlation was better in females at 0.66, compared to males at 0.55, and weaker in older age groups at 0.42, as compared to the youngest age group at 0.59. Overall, 29.8% of the population was reclassified based on their DEXA %BF measures.
CONCLUSIONS
In a 5-year cohort worker compensation population, BMI was an inaccurate measure of true obesity.
未标注
评估在工伤赔偿人群中，身体质量指数（BMI）相较于直接测量的双能X线吸收法体脂百分比（DEXA %BF）的准确性。
方法
在5年期间，通过Pearson相关系数评估1394例可评估患者中BMI与DEXA %BF之间的一致性。计算敏感性和特异性以衡量BMI识别真正肥胖和非肥胖个体的能力。
结果
使用至少30kg/m²来识别肥胖，BMI的特异性为0.658，敏感性为0.735。女性的相关性更好，为0.66，而男性为0.55；老年组的相关性较弱，为0.42，而最年轻组为0.59。总体而言，29.8%的人群根据其DEXA %BF测量结果被重新分类。
结论
在一个为期5年的工伤赔偿队列人群中，BMI是真正肥胖的不准确测量指标。
