MedicalResearch.com: What is the background for this study?

Response: Previous research has investigated how childhood asthma and early wheeze can develop as the result of a complex interaction between environmental exposures, such as tobacco exposure, older siblings and an individual’s genetic profile. Genes associated with childhood asthma risk are located on chromosome 17, called 17q21. Our study asked the question: could the effect of 17q21 on respiratory symptoms in infants be modified by breastfeeding?

MedicalResearch.com: What are the main findings?

Response: Our findings demonstrate for the first time that the 17q21 genotype may have a dual effect on respiratory symptoms in the 1st year of life, depending on whether a child is breastfed or not.

MedicalResearch.com: What should readers take away from your report?

Response: Infants who are in possession of the susceptible genotype may be protected by breastfeeding. However, when infants were not breastfed, those infants who carried this genotype exhibited a trend towards an increased risk of having respiratory symptoms in the 1st year of life.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: Future research should replicate our findings and investigate if this effect persists into later childhood.
