The aim of this study is to investigate the relation between body mass index (BMI) and body fat (BF) among Lebanese female adolescents.
51 Lebanese females aged 12 to 18 years participated in this study. BMI was calculated as weight/height. Adiposity was measured by dual energy X-ray absorptiometry (DEXA).
Correlation coefficient of percent body fat (%BF) with BMI is 0.82. Correlation coefficient of fat mass (BF) with BMI is 0.93. The two linear regression formulas are: %BF = 6.89 + (1.1 *BMI) and BF = - 0.425 + (129 *BMI).
Correlations of BMI with DEXA measurements were higher with BF than %BF. For a given BMI, Lebanese girls have a higher than expected %BF. Based on the current findings, there may be a need to develop new cutoff points. From a public health perspective, this may considerably increase the prevalence of obesity among Lebanese female adolescents.
本研究旨在调查黎巴嫩女性青少年的体重指数（BMI）与体脂（BF）之间的关系。
51名年龄在12至18岁的黎巴嫩女性参与了本研究。BMI计算为体重/身高。采用双能X线吸收法（DEXA）测量肥胖程度。
体脂百分比（%BF）与BMI的相关系数为0.82。脂肪量（BF）与BMI的相关系数为0.93。两个线性回归公式分别为：%BF = 6.89 +（1.1×BMI）和BF = - 0.425 +（129×BMI）。
BMI与DEXA测量结果的相关性中，BF比%BF更高。对于给定的BMI，黎巴嫩女孩的%BF高于预期。基于目前的研究结果，可能需要制定新的临界值。从公共卫生角度来看，这可能会大幅增加黎巴嫩女性青少年肥胖的患病率。
