什么是BMI？
BMI（身体质量指数）是使用身高和体重来评估健康状况的指标。它通过体重（公斤）除以身高（米）的平方来计算。
BMI计算公式
BMI = weight(kg) ÷ height(m)²
BMI = 体重（公斤）÷ 身高（米）²。例如，体重70公斤、身高175厘米的人的BMI为70 ÷ 1.75² = 22.9。
健康体重管理建议
- ✓BMI只是参考指标；它不考虑肌肉量或体脂率
- ✓定期锻炼和均衡饮食很重要
- ✓快速体重变化可能对健康有害
- ✓咨询医疗专业人士以获得准确的健康评估

What is Pediatric BMI?
Pediatric BMI evaluates weight status in children and teens (ages 2-19). Unlike adults, it uses age and sex-specific percentiles, showing where a child stands compared to peers.

❓ FAQ
Can I use adult BMI calculator for my child?
No. Children are still growing, so age-specific percentiles are needed. Adult BMI standards only apply to ages 18+.
Should my overweight child go on a diet?
Strict diets are not recommended for growing children. Focus on healthy eating habits and increased activity. Consult a pediatrician.
How often should I check percentiles?
Typically at regular check-ups (every 6-12 months). Check more often if there are rapid changes or concerns.
💡 Tracking growth trends over time is more important than a single measurement.
