Background: Age at onset and clinical presentation of celiac disease have often been related to the age of gluten introduction into the diet. It has also been shown that breast feeding delays the onset of the disease.

Patients and methods: This retrospective study attempts to evaluate the respective contributions of these two parameters in the determination of the age at onset of the symptoms in celiac Tunisian children.

Results: One-hundred-sixty-nine children were studied. Mean duration of breast feeding in our population was 9.6 +/- 8.9 months and mean age of gluten introduction was 5.6 +/- 3.2 months. The mean age at onset of the disease was 15 +/- 8.7 months and mean latency time between gluten introduction and onset of the disease was 9.5 +/- 7.8 months. Both variables, duration of breast feeding and age at gluten introduction were strongly correlated to the age at onset of the disease (r = 0.47 and 0.40, respectively). Only breast feeding was correlated to the variable latency time (r = 0.33). Stepwise multiple regression analysis showed that the two variables independently influenced the age at onset with coefficients of regression of 0.90 +/- 0.20 and 0.26 +/- 0.07, respectively. Only breast feeding influenced the latency time with a coefficient of regression equal to 0.26 +/- 0.07.

Discussion: Our study confirms the independent effect of breast feeding in the determination of the age at onset of the disease. Breast feeding has two effects: an indirect effect, by delaying the introduction of gluten, and a direct effect, by increasing the latency time between gluten introduction and onset of the disease.

Conclusion: Prolonged breast feeding, at least until the 6th month, and gluten introduction started at least at the 5th month of life, significantly delay the onset of the disease. Gluten introduction should be done progressively and under breast feeding protection. Introduction of gluten 2 months before weaning has a protective effect.
