CORNEJO E, Verónica et al. STUDY ON DILUTION OF THREE TYPES OF POWDERER MILK IN FAMILIES BELONGING TO SOCIOECONOMIC GROUPS: ABC1, C2 AND C3 IN SANTIAGO. Rev. chil. nutr. [online]. 2007, vol.34, n.4, pp.353-363. ISSN 0717-7518. http://dx.doi.org/10.4067/S0717-75182007000400009.
Introduction: The liquid and powdered forms of cow milk are comparable when the reconstitution of the powdered milk is adequately done. Objective: To evaluate the dilution of three types of powdered milk: whole, low-fat and non-fat, in three socioeconomic groups (SEG): upper (ABC1), upper-middle (C2) and lower-middle (C3) in Santiago. Methodology: There were 1050 surveys performed in 350 homes in each SEG representing 300,000 homes. The dilution of powdered milk was compared using the norms established by the Ministry of Health and the Food Health Regulations. Results: Of the total, 4.4% were SEG ABC1, 17,6% C2 and 78% C3. The age distribution was 24.2 % in < 15 years old, 50% in those between 15 and 60 years old and 25,3% in > 60 years old. It was observed that adequate dilution diminishes as age increases, showing that between 1 to 2 years of age and 2 to 5 years of age, 51.2% and 45.9% from ABC1 and 36.9% and 18.7% from C3 decrease, respectively. Evaluating the entire population, it was observed that 77.4% of ABC1, 89.6% from C2 and 78.2% from C3 dilute milk deficiently. Establishing differences between groups, it was observed that C2 dilute 2.6 times more deficiently than ABC1. However there were no differences between SEC ABC1 and C3, both diluting deficiently in the same proportion. Conclusion: As age increases, the percentage of deficient dilution increases, independent of age group, type of milk and SEC
