The best way to calculate the perfect weight is to use the body mass index (BMI). For this age, the gender is not quite relevant, because the levels of physical development in boys and girls are pretty much similar around the age of 10. To calculate your child’s BMI you need his or her weight and height. The results are compared to statistical data, giving you a final percentile. A BMI percentile of 45 per cent means that your child weights more than 45 per cent of the kids of his age.
Having in mind that the values considered normal (healthy children) range between five and 85 per cent, with those below five per cent being underweight, and those above 85 per cent overweight or obese, we could easily conclude that the normal standards are quite permissive. Yet, it’s obvious that the closer to 50 per cent, the better. This is the place where genes may prove important, so consider corroborating such data with further information about the race and the family inheritance of your little one.
Children develop in different ways and each one’s metabolism has its own pace. This is the main reason why we should understand that the ideal weight is just a reference point to guide us with nutrition and physical exercises. As long as your child has a good perception on his or her body and the BMI percentile is between the abovementioned limits, you’re heading the right direction.
