Insights
Baby swimming in infancy may increase the risk of wheezing in children, particularly those with atopic mothers. Further research is needed to confirm this association in infant health outcomes.
Area of Science:
- Pediatric respiratory health
- Infant developmental studies
- Epidemiology
Background:
- Infant swimming programs are popular globally.
- The potential impact of early life exposures on respiratory health is a key area of research.
- Understanding risks associated with infant activities is crucial for parental guidance.
Purpose of the Study:
- To investigate the association between baby swimming in the first six months of life and respiratory diseases.
- To assess the incidence of lower respiratory tract infections (LRTI), wheeze, and otitis media from six to 18 months of age.
- To identify potential risk factors for respiratory conditions in early childhood.
Main Methods:
- Utilized data from The Norwegian Mother and Child Cohort Study (MoBa) with 30,870 children.
- Analyzed health outcomes including LRTI, wheeze, and otitis media between six and 18 months.
- Employed logistic regression analysis to estimate the effect of baby swimming, adjusting for confounders.
Main Results:
- Approximately 25% of children participated in baby swimming.
- No increased likelihood of LRTI, wheeze, or otitis media was found in children who participated in baby swimming.
- However, children with atopic mothers who swam as babies showed an increased risk of wheeze (aOR 1.24).
- Infants without prior respiratory issues also showed a slight increase in wheeze risk if they participated in baby swimming (aOR 1.08).
Conclusions:
- Baby swimming might be linked to a later onset of wheeze in infants.
- The association appears stronger in infants with atopic mothers or those without pre-existing respiratory conditions.
- Further investigation is warranted to confirm these findings and understand the underlying mechanisms.
Aim:
To estimate the effect of baby swimming in the first 6 months of life on respiratory diseases from 6 to 18 months.
Methods:
We used data from The Norwegian Mother and Child Cohort Study (MoBa) conducted by the Norwegian Institute of Public Health in children born between 1999 and 2005 followed from birth to the age of 18 months (n = 30,870). Health outcomes: lower respiratory tract infections (LRTI), wheeze and otitis media between 6 and 18 months of age.
Exposure:
baby swimming at the age of 6 months. The effect of baby swimming was estimated by logistic regression analysis adjusting for potential confounders.
Results:
About 25% of the children participated in baby swimming. The prevalence of LRTI was 13.3%, wheeze 40.0% and otitis media 30.4%. Children who were baby swimming were not more likely to have LRTI, to wheeze or to have otitis media. However, children with atopic mothers who attended baby swimming had an increased risk of wheeze, adjusted odds ratios (aOR) 1.24 (95% CI 1.11, 1.39), but not LRTI or otitis media. This was also the case for children without respiratory diseases before 6 months aOR 1.08 (95%CI 1.02-1.15).
Conclusion:
Baby swimming may be related to later wheeze. However, these findings warrant further investigation.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
