Recent research has challenged the long-held belief that breastfeeding reduces the risk of asthma and other allergic conditions in children. For over 70 years, this topic has been widely debated, but no clear consensus has been reached. Most of the evidence comes from observational studies, which are not always reliable. However, a major randomized study published in the British Medical Journal offers new insights.
The study, conducted between December 2002 and April 2005, involved 17,046 mothers from 31 maternity hospitals. These mothers were randomly assigned to either a breastfeeding group or a control group. The researchers encouraged the test group to breastfeed for longer periods. After following up with 13,889 children until they were 6.5 years old, they used questionnaires to assess asthma, pollen allergies, and eczema, as well as skin prick tests to check for sensitivities to dust mites, cats, birch pollen, mold, and hay.
The results showed that prolonged breastfeeding did not lower the risk of developing asthma, pollen allergies, or eczema by age 6.5. Additionally, there was no significant difference in the rate of positive skin tests between the groups. Researchers concluded that extending breastfeeding does not appear to affect the likelihood of children developing hereditary allergic conditions like asthma or eczema.
This study adds important clarity to a controversial topic and highlights the need for more rigorous, large-scale trials to fully understand the impact of breastfeeding on long-term health outcomes.
