(HealthDay News) -- Repeated antibiotic use is linked to greater weight gains in children, and it could affect their weight for the rest of their lives, a new study suggests.
Researchers from the Johns Hopkins Bloomberg School of Public Health in Baltimore analyzed data from nearly 164,000 youngsters in the United States, and found that about 21 percent of them received seven or more prescriptions for antibiotics during childhood.
At age 15, those who took antibiotics seven or more times at earlier ages weighed about 3 pounds more than those who took no antibiotics. This weight gain among those who frequently took antibiotics was likely underestimated due to lack of complete data, the researchers said.
