Researchers found specific practices thought to promote childhood obesity – from putting infants to bed with bottles to feeding them while watching television – were more common in certain racial and ethnic groups compared to others. “Rather than focus on the ethnic and racial differences, these results show us that we can all do better and begin our efforts to prevent obesity earlier in life,” lead author Dr. Eliana Perrin told Reuters Health. More than one quarter of U.S. children aged two to five years old are overweight or obese, according to Perrin and her coauthors, whose results are published in Pediatrics. The researchers asked parents about a variety of behaviors that have been linked to childhood obesity in previous research.
