Over Weight

The infants were considered overweight if they had a body mass index (BMI) above the 85th weight-for-height percentile on 2 or more measurements taken at least 3 months part. This means that 85 percent of children their age and gender have a lower BMI, which is a measure of weight in relation to height.

In the first study, the researchers found that infants between the 85th and 94th weight-for-height percentiles actually had fewer hospital admissions and repeat admissions than normal-weight infants. However, higher than expected admission rates were seen in the most overweight infants (95th or higher percentile).

In the second study, overweight infants were more likely than their normal-weight peers to have developmental delays and snoring. There was also evidence that asthma and other breathing problems were more common in overweight infants.
