Key takeaways:
- Researchers discovered elevated odds for extreme bronchiolitis hospitalization in infants with family cleansing product publicity 1 to three days per week.
- This was noticed after accounting for a number of covariates.
Infants uncovered to family cleansing merchandise 1 day or extra per week throughout their first 12 months of life had been extra prone to expertise extreme bronchiolitis hospitalization, based on research outcomes.
This discovering was revealed in The Journal of Allergy and Scientific Immunology: In Observe.
Knowledge had been derived from Dumas O, et al. J Allergy Clin Immunol Pract. 2025;doi:10.1016/j.jaip.2025.03.032.
“Though indirectly comparable, our findings are in line with a research [by Casas and colleagues] in school-age kids reporting an affiliation between use of bleach at dwelling and elevated danger of respiratory infections,” Orianne Dumas, PhD, CR, HDR, occupational and respiratory epidemiologist from the Middle for Analysis in Epidemiology and Inhabitants Well being, Integrative Respiratory Epidemiology crew in Villejuif, France, and colleagues wrote.
“Our outcomes must also be interpreted in mild of a number of research, primarily in adults, supporting direct airway injury induced by publicity to irritant cleansing merchandise,” they continued.
In a case-control research, Dumas and colleagues assessed 813 U.S. infants hospitalized with extreme bronchiolitis from the thirty fifth Multicenter Airway Analysis Collaboration (MARC) research and 626 wholesome U.S. infants from the forty third MARC research to find out how family cleansing product use is linked to bronchiolitis hospitalization.
The research famous that the bronchiolitis hospitalizations befell throughout the 2011 to 2014 winter seasons, and the wholesome infants had no “identified main medical situations or earlier hospitalization for bronchiolitis or some other respiration downside.”
Between the infants hospitalized with extreme bronchiolitis and the infants deemed wholesome, researchers discovered that a number of traits considerably differed, together with:
- age (median, 3 months vs. 4 months);
- intercourse (feminine, 41% vs. 48%);
- race and ethnicity (non-Hispanic Black, 22% vs. 26%; Hispanic, 29% vs. 21%);
- median family revenue (≥ $80,000, 23% vs. 40%);
- medical health insurance (non-public, 41% vs. 60%);
- maternal smoking throughout being pregnant (14% vs. 8%);
- variety of siblings (three or extra siblings, 40% vs. 24%);
- breastfeeding (48% vs. 67%); and
- maternal age at supply (youthful than 25 years, 27% vs. 15%).
At two occasions associated to their little one’s age (42 to 48 months outdated and 54 to 60 months outdated), dad and mom had been requested in regards to the frequency of cleansing product use at dwelling throughout the little one’s first 12 months of life in a cellphone interview.
Based mostly on these responses, the research reported {that a} considerably better proportion of fogeys of infants hospitalized with extreme bronchiolitis vs. deemed wholesome used family cleansing merchandise 1 to three days per week (54% vs. 50%) and 4 to 7 days per week (36% vs. 31%).
Researchers went on to seek out heightened odds for extreme bronchiolitis hospitalization in infants with family cleansing product publicity 1 to three days per week vs. by no means/lower than as soon as every week (adjusted OR = 1.83; 95% CI, 1.28-2.62) in a mannequin that accounted for the 9 traits outlined above.
Equally, family cleansing product publicity 4 to 7 days per week vs. by no means/lower than as soon as every week raised the probability for extreme bronchiolitis hospitalization throughout infancy (aOR = 1.76; 95% CI, 1.2-2.58), based on the research.
Researchers highlighted that this sample continued in two extra logistic regression fashions: a mannequin moreover adjusted for daycare attendance and untimely start (1-3 days/week, aOR = 1.74; 95% CI, 1.2-2.51; 4-7 days/week, aOR = 1.64; 95% CI, 1.11-2.43), and a mannequin that solely included the 5 facilities the place each units of infants had been enrolled (1-3 days/week, aOR = 2.25; 95% CI, 1.36-3.73; 4-7 days/week, aOR = 1.88; 95% CI, 1.09-3.23).
“These outcomes help additional research to find out whether or not lowered publicity to cleansing merchandise improves respiratory well being,” Dumas and colleagues wrote.

Perspective
The research by Dumas et al presents compelling proof that frequent family cleansing product use is related to a considerably elevated danger of hospitalization for bronchiolitis in infants.
These findings are each important and regarding, significantly as a result of they spotlight a modifiable environmental danger issue. These findings will not be completely stunning, given the rising physique of proof that family cleansing brokers, particularly within the spray kind, can contribute to respiratory issues equivalent to wheezing in younger kids.
As a clinician, I discover these outcomes impactful. In my very own expertise, dad and mom of hospitalized infants usually don’t think about cleansing merchandise to be potential contributors to their little one’s sickness. Whereas we routinely counsel on smoking cessation, discussions round chemical cleansing brokers are uncommon. This research gives a data-driven rationale to broaden these conversations.
We might counsel dad and mom of infants, particularly these with pre-existing danger components, to attenuate using cleansing sprays and robust disinfectants within the little one’s setting. We will embody an environmental historical past as a part of the routine steering throughout toddler care visits. We will additionally advocate for safer options and improved labeling of family cleansing brokers significantly marked as little one pleasant.
Future analysis ought to purpose to call which kinds of merchandise or software strategies equivalent to sprays or wipes confer the very best danger, in addition to finding out the mechanisms of damage or irritation equivalent to airway microbiome disruption and whether or not sure infants are extra prone. Subsequent steps might additionally discover long-term respiratory outcomes past the interval of acute hospitalizations for bronchiolitis.
Total, this research is a necessary step ahead in our understanding of how the house setting shapes early-life respiratory outcomes and opens the door to significant, preventative methods.
