Duration and exclusiveness of breastfeeding and risk of childhood atopic diseases

Abstract

Background

Breastfeeding may have immune modulatory effects that influence the development of childhood allergic sensitization and atopic diseases. We aimed to examine the associations of breastfeeding with childhood allergic sensitization, inhalant or food allergy and eczema, and whether any association was affected by disease-related modification of the exposure or modified by maternal history of maternal history of allergy, eczema or asthma.

Methods

This study among 5,828 children was performed in a population-based prospective cohort from fetal life onwards. We collected information on duration (<2 months, 2-4 months, 4-6 months and ≥6 months) and exclusiveness (non-exclusive vs. exclusive for 4 months) of breastfeeding in infancy by postal questionnaires. At age 10 years, inhalant and food allergic sensitization were measured by skin prick tests, and physician-diagnosed inhalant and food allergy by a postal questionnaire. Data on parental-reported eczema were available from birth until age 10 years.

Results

We observed no association of breastfeeding with any allergic sensitization, physician-diagnosed allergy, or combination of these outcomes. Shorter breastfeeding duration was associated with an overall increased risk of eczema (p-value for trend <0.05). Non-exclusively breastfed children had an overall increased risk of eczema (aOR (95% CI): 1.11 (1.01, 1.23)), compared with children exclusively breastfed for 4 months. Risk period-specific sensitivity analyses, additional adjustment for ointment use for eczema at age 2 months, and cross-lagged modeling showed no consistent results for disease-related modification of the exposure. Results were not modified by maternal history of allergy, eczema or asthma (lowest p-value for interaction =0.13).

Conclusions

Shorter duration or non-exclusiveness of breastfeeding is associated with a weak overall increased risk of eczema but not allergic sensitization or physician-diagnosed allergy at age 10 years
