A new study has found that only-children are more likely to be overweight or obese compared with children who have siblings.
The research revealed that families with two or more children tended to have more healthy eating and drinking habits than families with only-children or “singletons,” as the researchers called them.
Although the study population was small and the research could not determine cause and effect, the findings do “raise an interesting point that we need to better understand,” says Natalie Muth, who chairs the American Academy of Pediatrics Section on Obesity.
