Infant weight gain

The answer is B.

A team of researchers at the Children's Hospital of Philadelphia recently concluded that babies can gain weight too quickly for their own good.

The research group studied more than 19,000 children born between 1959 and 1965, and found that babies who gained weight very quickly during their first four months were more likely to be overweight at age 7 than were other babies. It didn't matter how much they actually weighed at birth or at one-year old. It was how quickly they put on the pounds that counted.

But the researchers also warned there are still lots of questions to be answered. It's possible, they said, that early fast weight gain is due genetic factors kicking in that will make the children susceptible to obesity. Or it may be that parents who overfeed their infants are more likely to do so later in childhood as well.

Nonetheless, the researchers said the study results could help improve our understanding of obesity issues. They also noted that the American Academy of Pediatrics strongly supports breastfeeding as the best source of nutrition for babies.
