Early solid food diet and eczema in childhood: a 10-year longitudinal study.

Abstract

The relationship between early solid feeding in the first four months and risks of eczema in childhood was examined in a birth cohort of 1265 children studied to the age of 10 years. The major findings of this analysis were: 1) children exposed to a diverse solid food diet during their first four months had risks of eczema in early childhood which were about 1.6 times those of children who were not introduced to solid food by age four months. These associations persisted when a range of confounding factors (including family history of atopic disease, infant milk diet (breast/bottle) and family social background factors) were taken into account. 2) Similar associations between early infant diet and risks of chronic and recurrent eczema up to the age of ten years were also found. It was estimated that after adjustment for confounding factors, children exposed to an early diverse solid food diet had risks of eczema which were over 2.5 times those of children not introduced to solid feeding. These results are generally consistent with the hypothesis that early exposure to a diverse solid food diet may increase risks of eczema in children who are susceptible to this condition.
