BMI in children and adults

Just like in adults, body fat in children also varies with the sex of the child. For accuracy, BMI chart for specific age is used to determine the overall index in children. The BMI chart table locates which percentile the child falls in. The interpretation for the chart should be guided by:

  • If the child’s BMI falls below the 5th percentile, then they are underweight
  • The healthy weight in children should be located between 5-85th percentile
  • Above 85th to the 95th percentile, the child is overweight
  • Being in the 95th, or above, the child is obese.

To ascertain the BMI chart for age and sex, evaluation of the child’s diet, skin-fold thickness, and family history should not be ignored. It is, however, important to note that as the child grows in height and weight, the healthy weight will keep on changing.

BMI chart limitations

i. Athletes, bodybuilders, and people with high muscular builds find BMI chart unreliable as it overestimates their body fat. From the charts, these people become obese and morbidly obese. In the chart, there is no room for body composition considerations and fat-free mass ratio. Also, it never really factors ethnic differences.

ii. The chart is misleading to older adults as they may have lost some muscle mass which contributes to their weight. One may be healthy but have low muscle mass leading to accelerated aging and they grow weaker.

In conclusion, a healthy weight is just the best way to go as it averts weight-related diseases like type 2 diabetes and hypertension. The BMI chart is just one of the many metrics that will boost your confidence knowing that you fall under the healthy BMI. Get calculating with BMI calculator to know your BMI.
