title: Increased fecal IgE among infants in a rural community of Egypt: an analysis of associated risk factors.
abstract: Newborns in rural Bilbeis, Egypt were followed to 1-year of age to document the incidence and risk factors associated with the development of fecal IgE. Factors associated with increased fecal IgE included infants aged 3-6 months (relative risk (RR) = 3.28, 95 per cent confidence intervals (CI) = 1.03-13.60, p < 0.05) and mother being vaccinated antenatally (RR = 2.17, CI - 1.01-4.61, p < 0.05). Decreased fecal IgE was observed with consumption of rice (RR = 0.37, CI = 0.12-0.94, p < 0.05), biscuits (RR = 0.43, CI = 0.15-0.99, p < 0.05), potatoes (RR = 0.39, CI = 0.11-0.98, p < 0.05), and fruits and vegetables (RR = 0.20, CI = 0.02-0.80, p < 0.05). After multivariate adjustment, increased risk was observed with consumption of milk pudding (RR = 7.48, CI = 1.54-36.20, p < 0.05) and wet-nursed infants (RR = 2.77, CI = 1.17-6.54, p < 0.05). Infants who were completely breastfed (RR = 0.13, CI = 0.02-0.68, p < 0.05) and infants' family owning a television set (RR = 0.29, CI = 0.12-0.67, p < 0.05) were less likely to develop fecal IgE. Our findings indicate that prelacteal feeding with certain foods, early supplementation of breastfeeding, and sociodemographic factors are associated with increased fecal IgE.
