PCORnet Study Finds Small Link between Childhood Obesity and Antibiotics

A study conducted within the National Patient Centered Clinical Research Network (PCORnet) and published in the journal, Pediatrics found a small association between early antibiotic exposure and weight gain in young children.

The study, “Early Life Antibiotic Use and Weight Outcomes in Children Ages 48 to <72 Months of Age,” is the largest to tackle the issue, involving a sample of over 360,000 children from 35 institutions across the country. Researchers examined the relationship between antibiotic use among children less than two years old and their weight at around five years old, analyzing such factors as: diagnosis of chronic conditions, number of antibiotic prescriptions given to children, and the specific types of antibiotics given.
