Body mass index (BMI) has limited diagnostic performance due to its inability to discriminate between fat and lean mass. This study was conducted to compare the effectiveness of body fat percentage (BFP) against BMI in defining body composition.
A cross-sectional study was conducted on students aged 17-30 years in Melaka, Malaysia. Basic anthropometric measurements were acquired using a manual weighing scale, measuring tape and a fixed stadiometer. BFP was calculated using the United States Navy formula. Data was tabulated and analysed using Epi Info and Statistical Package for the Social Sciences software. Pearson's correlation coefficient and Kappa values were used. A p-value < 0.05 was considered statistically significant.
Out of the 490 subjects recruited, 43% of males and 24.6% of females were found to be overweight, while 14.3% of males and 7.8% of females were obese, when calculated using BMI. However, 8.9% of males and 22.8% of females were considered obese based on the BFP.
BFP plays a more important role in distinguishing between healthy and obese individuals, as it has a greater ability to differentiate between lean mass and fat mass compared to BMI.
由于无法区分脂肪和瘦肉，体重指数 (BMI) 的诊断性能有限。本研究旨在比较体脂肪百分比 (BFP) 与 BMI 在定义身体成分方面的有效性。
在马来西亚马六甲对 17-30 岁的学生进行了一项横断面研究。使用手动体重秤、卷尺和固定身高计获取基本人体测量值。使用美国海军公式计算 BFP。使用 Epi Info 和社会科学统计软件包对数据进行制表和分析。使用 Pearson 相关系数和 Kappa 值。p 值 < 0.05 被认为具有统计学意义。
在招募的 490 名受试者中，43%的男性和 24.6%的女性被认为超重，而 14.3%的男性和 7.8%的女性被认为肥胖，这是根据 BMI 计算的。然而，根据 BFP，8.9%的男性和 22.8%的女性被认为肥胖。
BFP 在区分健康和肥胖个体方面发挥着更重要的作用，因为它比 BMI 更能区分瘦体重和脂肪量。
