Evaluating Oral Nutritional Supplements on Children's Nutritional Status and Digestive Health in Vietnam.

Evaluating the efficiency of using Oral Nutritional Supplementation toward nutrition status (anthropometric index, the prevalence of wasting), digestive disorders, and anorexic in children aged 24 - 71 months.

Evaluating the efficiency of using Oral Nutritional Supplementation toward the improvement of the anthropometric index (weight, height, weight for age Z-score, height for age Z-score, and weight for height Z-score ), nutrition status (the prevalence of wasting) in children aged 24 - 71 months after 3 months using the nutrient product.

Evaluating the efficiency of using Oral Nutritional Supplementation for digestive disorders and anorexic in children aged 24 - 71 months.

The research involves a randomized controlled clinical trial (RCT). The plan is expected to conduct from 2022 to 2023 with over 600 children aged 24-71 months. The nutrient product produces a high amount of energy that provides over 472kcal/100g; 15,6g/100g of protein; 20,8g/100 of fat; 55,6g/100g of carbonhydrate; 338mg/100g of alpha-Linolenic acid; 1800mg/100g of Linoleic acid; 19,7mg/100g of 2'FL HMO; 1088mg/100g of MCT; 2700mg/100g of FOS/Inulin; 55mg/100g of GOS; 1000mg/100g of Lysine; 687mg/100g of Calcium; 68mg/100g of Magnesium; 6,5mg/100g of Iron; 3,6/100g of Zinc; 41,9µg/100g of Manganese; 2176IU/100g of Vitamin A; 376 IU/100g of Vitamin D3; 44µg/100g of Vitamin K1; 820µg/100g of Vitamin B1; 900µg/100g of Vitamin B2; 610µg/100g of Vitamin B6; 1,92µg/100g Vitamin B12; 4140µg/100g of Acid Pantothenic; 115µg/100g of Acid Folic; 98,2 grams of the product, which equals 2 packs (230ml x 2 per day) will supply about 36,4% - 48,1% of the required energy for children aged 2-5 years old. Additional components include Alpha-Linolenic Acid, which provides 67% of the recommended dietary allowances (RDAs), Linolenic Acid 60, which provides 90% RDAs, and 25 other micronutrients and minerals that include some essential vitamins such as Calcium 112-114% RDAs, Iron 118-120.4% RDAs, Vitamin A 145-174% RDAs, Zinc 75-87% RDAs, Vitamin D3 62% RDAs, Seleni 53-63% RDAs, Vitamin K 63-73% RDAs, Folic Acid 76-115% RDAs. With other elements such as 2'FL HMO (19,7 mg), FOS/inulin (2700 mg), Choline ( 47 mg, Taurine 20 mg) , multi medium-chain triglyceride (MCT) (1088 mg), Bifidobacterium longum (109 CFU). The study will be conducted at schools and homes: 600 children erratically divided into 2 groups, 1 group will use the product for 3 months ( with the amount of use: twice per day, 49,2 grams each time). The product will be distributed to the students through the schools. Monitoring will be performed carefully by the commune and district Health Department and the Centers for Disease Control and Prevention weekly. The study aims to evaluate the efficiency of nutrient products toward nutrition status ( anthropometric index, the prevalence of wasting), digestive disorders, and anorexic in children aged 24-71 months.
