Milk Supplementation and Bone Health in Children

29. september 2021 opdateret af: Yu-ming Chen, Sun Yat-sen University

Effects of Yili Child Formula Milk on Bone Health in 4-6 Year Children: a 12-month Randomized Controlled Trial

Objectives: to examine the effects of a Yili child formula milk and regular milk on bone health and growth in young children.

Study design: cluster randomized controlled trial.

Setting: kindergartens in Hui-ning County of Gansu Province, China (north west).

Participants: >=246 apparent healthy children aged 4-6 years old.

Interventions:

(I) Yili child formula milk (QQ star formula, SCI-PRO NUTR5+6TM), 195 ml *2 /day; (II) Yili regular milk (pure milk), 195ml*2 /day; (III) Controls: about 50g/d grain foods (containing 20-30 g carbohydrates), e.g. bread.

Interventional Duration: 12 months.

Outcome measures: determined at 0, 6 and 12 months post treatments. Primary outcomes: bone density and bone mineral contents at the forearm and heel, bone biomarkers.

Secondary outcomes: (1) anthropometric indices: weight, height, waist circumference, etc.; (2) immune status.

Other measures: dietary intakes, physical activities, general information, medical information, adverse of side effects.

Data Analyses: The one-year changes and percent changes in the primary and secondary outcomes will be compared among the 3 groups.
