Study Design and Population
This study was embedded in the Generation R Study, a multiethnic, population-based, prospective cohort study, which follows mothers and their children from fetal life onward, in Rotterdam, the Netherlands. The design of the Generation R Study has been described in detail elsewhere.19 Of the 9749 children born between April 2002 and January 2006, 7893 were available for the postnatal follow-up. Complete dietary information around 1 year of age was available for 3629 children, after exclusion of
Subject Characteristics
Table 1 shows the characteristics of the study population. Of the 1997 children, 1.4% (n = 27) was TG2A positive at the median age of 5.9 years. Girls represented 49% of the TG2A-negative group and 56% of the TG2A-positive group (P = .51); 78% of the TG2A-negative children and 89% of the TG2A-positive children were white (P = .17). TG2A-positive children had lower weight at the 6-year follow-up visit to the research center (20.2 vs 22.0 kg; P < .001) and were more often HLA-DQ2/8 positive (90%
Discussion
In this study, we aimed at identifying possible associations between common dietary patterns of infants around the first year of life and the risk of developing celiac disease autoimmunity at the age of 6 years. Five empirical dietary patterns were used to characterize the children’s food consumption: the diet quality score extracted a priori on the basis of existing recommendations for preschool children,25 3 dietary patterns extracted a posteriori by principal component analysis, and 1
Conclusions
Our results suggest that an early-life dietary pattern rich in vegetables, grains, and vegetable oils and with low consumption of sugar, confectionery products, and refined cereals is associated with a lower risk of developing celiac disease autoimmunity at 6 years of age. These findings may be useful in identifying possible underlying mechanisms linking diet and celiac disease and thus contribute to the development of new dietary-based prevention strategies for genetically predisposed
