Role of functional nutrition in reducing the incidence of acute respiratory infections in children
Objective. To study the role of adapted formulas and drinks in reducing the incidence of acute respiratory infections (ARIs) in infants and toddlers. Patients and methods. This study was conducted in two stages: stage 1 included infants (0–1 year) (n = 105), and stage 2 included the same children aged 1 to 3 years (n = 96). In the control group (n = 35, 0–1 year; n = 32, 1–3 years), children were breastfed during the first year of life.
