Frequently Asked Questions
BMI是如何计算的？▼
BMI = 体重(kg) / 身高(m)²。例如，体重70kg、身高175cm的人BMI = 70 / (1.75)² = 22.9。
为什么亚洲人的BMI标准不同？▼
研究表明，与西方人相比，亚洲人在较低BMI值时体脂率更高、健康风险更大。WHO西太平洋区域建议亚洲人BMI 23以上为超重、25以上为肥胖，而西方标准分别为25和30。
BMI是可靠的健康指标吗？▼
BMI是有用的筛查工具但有局限性。它不区分肌肉和脂肪，所以肌肉发达的人可能被归类为超重。也不考虑脂肪分布——腹部脂肪带来更高健康风险。完整评估应同时考虑腰围和体脂率。
