Overview

This study will evaluate the incidence of allergic manifestations (the first of which is atopic dermatitis) and infectious diseases in children fed with an infant formula under real conditions of use.

  • Observance
    • Time Frame: 3, 6 and 12 months
    • % of children who consumed the formula prescribed by the doctor at the previous visit
  • Consumption
    • Time Frame: 3, 6 and 12 months
    • Number of days of consumption during the previous period.
  • Satisfaction with Likert scale
    • Time Frame: 3, 6 and 12 months
    • 5-level Likert scale filled in by the doctor and by parents
  • Cumulative incidence of allergic manifestations
    • Time Frame: 3, 6 and 12 months
    • Cumulative number since the inclusion of episodes of: atopic dermatitis, eczema, wheezing, allergic rhinitis
  • Cumulative incidence of infections
    • Time Frame: 3, 6 and 12 months
    • Cumulative number since the inclusion of episodes of: Infection of the upper respiratory tract, Infection of the lower respiratory tract, Gastrointestinal infections, pyelonephritis,
