Frequent use of household disinfectants likely increases the childhood obesity

Updated: Jan 14, 2019

“We found that infants living in households where disinfectants were used at least weekly were twice as likely to have higher levels of the bacteria called Lachnospiraceae at three to four months of age,” said Anita Kozyrskyj, a U of A pediatrics professor and principal investigator on the SyMBIOTA project—an investigation into how alteration of the infant gut microbiome impacts health. “At three years of age, those same children had a higher body mass index (BMI) than children who were not exposed to frequent home use of disinfectants as infants.”


The study, published in the Canadian Medical Association Journal (CMAJ), used data from 757 children participating in AllerGen’s Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort, and examined exposure to three categories of household cleaners—disinfectants, detergents and eco-friendly products—on the infant gut microbiome.
