Breastfeeding and the prevalence of symptoms of allergic disorders in Japanese adolescents

Abstract

The findings suggest that breastfeeding may be associated with an increased prevalence of atopic eczema, especially among children without a parental history of allergy.

Allergic Rhinitis and its Impact on Asthma (ARIA) 2008*

“…More recent studies (1812)(1813)(1814) and meta-analyses (1815-1817) have not changed the results of the first one. Moreover, the risk of asthma was found to be enhanced in breastfed children after the age of 6 years in some (1818-1820) but not all prospective studies (1821,1822).…”

Effects of Early Nutritional Interventions on the Development of Atopic Disease in Infants and Children: The Role of Maternal Dietary Restriction, Breastfeeding, Timing of Introduction of Complementary Foods, and Hydrolyzed Formulas

“…This reverse causation effect may explain why some studies have found an increased incidence of atopic dermatitis in breastfed infants. [31][32][33] In summary, for infants at high risk of developing atopy, there is evidence that exclusive breastfeeding for at least 4 months or breastfeeding with supplements of hydrolyzed infant formulas decreases the risk of atopic dermatitis compared with breastfeeding with supplements of standard cow milk-based formulas. On the basis of currently available evidence, this is less likely to apply to infants who are not at risk of developing atopy, and exclusive breastfeeding beyond 3 to 4 months does not seem to lead to any additional benefit in the incidence of atopic eczema.…”

Breast-feeding and hospitalization for asthma in early childhood: a nationwide longitudinal survey in Japan

“…Although breast-feeding has long-term benefits for children's health such as prevention of overweight/obesity and type 2 diabetes and improvement of cognitive function (1) , the protective effect of breast-feeding on asthma in childhood still remains controversial (2)(3)(4)(5)(6)(7)(8)(9)(10)(11) . Two meta-analyses (4,5) and a recent study in New Zealand (6) reported that breastfeeding continued to be associated with decreased risk of asthma in children after cessation of breast-feeding.…”
