Household cleaning products may be making children fat, study suggests

The study analyzed the gut flora of 757 infants from the general population at age 3-4 months and weight at ages 1 and 3 years, looking at exposure to disinfectants, detergents and eco-friendly products used in the home. When that group was three-years-old, their body mass index was higher than children who didn't live in homes where disinfectants are frequently used. The gut had lower levels of Haemophilus and Clostridium bacteria but higher levels of Lachnospiraceae. Past research has found an elevated risk of wheezing in persons using these products and in their children, but limited information is available on overweight risk.

The findings were published in the Canadian Medical Association Journal (CMAJ) under the title, "Postnatal exposure to household disinfectants, infant gut microbiota and subsequent risk of overweight in children".

"We figured out that infants living in households with disinfectants being dilapidated a minimum of weekly were twice as likely to occupy increased ranges of the intestine microbes Lachnospiraceae at age Three-four months", feedback Anita Kozyrskyj, Ph.D., a College of Alberta pediatrics professor, and fundamental investigator on the SyMBIOTA challenge, an investigation into how adjustment of the baby intestine microbiome impacts on kid's health.

The study found infants in homes with high use of eco cleaners had a lower risk of becoming overweight or obese.

"Antibacterial cleaning products have the capacity to change the environmental microbiome and alter risk for child overweight", write the authors. There's no harm in using eco-friendly cleaners and adopting the healthiest lifestyle possible.

The CHILD research study birth cohort has been created to assess the impact of indoor environmental exposures, including household cleaning products, on postnatal health. Dr. Kozyrskyj suggests these moms can even occupy on the entire healthier existence, and delight in extra healthily at some level of pregnancy, shall we say, so their formative years inherit a extra wholesome microbiome.

One of the study's findings is that roughly 80% of Canadian households use disinfectant products, most often multi-surface cleaners, at least once weekly, said Kozyrskyj. "So it was a matter of dose", she said in an interview, noting that studies of piglets have found similar changes in the animals' gut microbiome when they were exposed to aerosol disinfectants in their enclosures.

However, the researchers cautioned that outside factors that potentially contribute to weight gain couldn't be ruled out in the study, including a mother's diet while pregnant. The researchers theorize that the close proximity of those cleansers has an impact on the bacteria in the environment and also inside the baby's intestines.

What is clear, however, is that adults can help protect infant gut microbiome and cut risk of weight gain and obesity by eliminating disinfectant agents in household cleaning regimes, concludes Kozyrskyj.

And "higher frequency of use of disinfectant was associated with higher abundance of Lachnospiraceae", said Kozyrskyj.

The study's authors say that points to a connection between cleaning disinfectants and gut bacteria, but caution more research is needed to confirm a causal relationship. However, she said the study did open her mind to using green products, including DIY vinegar cleaning solutions, in her own home.
