title: Maternal diet during lactation and allergic sensitization in the offspring at age of 5.
abstract: The objective of this study was to examine the effect of maternal dietary intake during lactation on allergic sensitization at the age of 5 in children carrying HLA-DQB1-conferred susceptibility to type 1 diabetes. We analyzed data for 652 consecutively born children with complete information on maternal diet and allergen-specific immunoglobulin E (IgE) measurements who are participating in the Finnish Type 1 Diabetes Prediction and Prevention (DIPP) Nutrition and allergy study. Analysis was performed using logistic regression. In models that included the significant uncorrelated dietary variables, maternal intake of butters and saturated fatty acids was associated with increased risk, while margarine was associated with a decreased risk, of sensitization to wheat allergen in the offspring. Maternal intake of potatoes, milks, and margarine and low-fat spreads were associated with decreased risk of sensitization to birch allergen. On the other hand, intake of potatoes decreased the risk, while vitamin C and eggs increased the risk, of cat allergic sensitization. Maternal intake of butters and saturated fatty acids during lactation may increase the risk, while margarines may decrease the risk, of sensitization to wheat allergen in the offspring. Maternal intake of potatoes, milks, and margarines may decrease the risk of sensitization to birch allergen. On the other hand, intake of potatoes may decrease the risk, while vitamin C and eggs may increase the risk, of cat allergic sensitization. These effects may persist regardless of maternal or parental allergic status.
