Abstract

Objective: To evaluate the effectiveness of using nutritional milk supplemented with colostrum on the nutritional status and respiratory immunity of children from 24 to 72 months old. Method: Community intervention, single-blind, controlled on 279 children from 24 to 72 months old at 2 kindergartens in Thai Nguyen, divided into 02 groups : the intervention group (n=141) used nutritional milk supplemented with colostrum, the control group (n=138) used the control product for 04 months (2 boxes of 180ml/day x 7 days/week). Anthropometric indicators, respiratory status interviews were assessed monthly, immune test indicators were tested at the beginning and end of the intervention. Results: After 4 months, the intervention group had a statistically significant increase in height and weight compared to the control group (2.94±0.64cm and 0.92±0.62kg, respectively, compared to 2.51±0.53cm and 0.81±0.53kg, p<0.001). The intervention group had a statistically significant increase in immune indices compared to the control group: including IgA, IgG and IgM concentrations (0.55±0.82 g/L compared to 0.43±0.63 g/L; 1.88±3.31 g/L compared to 1.26± 2.53 g/L and 0.61±0.66 g/L compared to 0.21±0.5 g/L). In the conditions of cough, fever, sneezing, runny nose, and difficulty breathing, the number of children with both the number of sick days and the number of sick episodes in the intervention group were reduced more than in the control group. Conclusion: Using nutritional milk products supplemented with colostrum for 4 months helps children improve their weight, height, and immunity better than regular milk.
