Asthma and infant diet
Insights
Early infant feeding practices, including breastfeeding and solid food introduction, showed no significant link to childhood asthma rates in a large birth cohort study. Further research is needed for high-risk families.
Area of Science:
- Pediatrics
- Allergology
- Epidemiology
Background:
- Childhood asthma is a significant public health concern.
- Early life feeding practices are hypothesized to influence asthma development.
- Understanding these early influences is crucial for prevention strategies.
Purpose of the Study:
- To investigate the association between infant feeding (breast milk and solids) in the first four months of life and the incidence of early childhood asthma.
- To determine if parental history of asthma modifies this relationship.
Main Methods:
- Prospective birth cohort study.
- Involved 1110 children.
- Data collected on milk diet and solid feeding practices within the first four months of life.
Main Results:
- No statistically significant association was found between breastfeeding or solid feeding practices and asthma rates.
- This finding held true for children with and without a parental history of asthma.
- Early breastfeeding did not demonstrate a detectable effect on subsequent asthma risk in this cohort.
Conclusions:
- Current evidence does not support a link between early breastfeeding or solid feeding and reduced asthma risk in the general population.
- Breastfeeding might still offer a protective effect for infants from highly atopic families, warranting further investigation.
Abstract:
The relationship of milk diet and solid feeding practices during the first 4 months of life to rates of early childhood asthma was studied prospectively in a birth cohort of 1110 children. The results of the analysis showed no significant association between rates of asthma and breast feeding or solid feeding practices. This was true for children both of asthmatic and non-asthmatic parentage. It is concluded that there is no evidence to indicate that early breast feeding had any detectable effect on the risk of subsequent asthma in this birth cohort. However, the possibility still remains that breast feeding may have a prophylactic effect for children from highly atopic families.
