A randomized double-blind controlled calcium supplementation trial, and bone and height acquisition in children.
There is limited information relating Ca intake to bone and height acquisition among Oriental children who consume little or even no milk.
The present controlled study investigated the acquisition of bone mass and height of Chinese children with an initial Ca intake of approximately 567 mg/d who were supplemented to about 800 mg/d. Eighty-four 7-year-old Hong Kong Chinese children underwent an 18-month randomized, double-blind, controlled Ca-supplementation trial.
The children were randomized to receive either 300 mg elemental Ca or a placebo tablet daily.
Bone mass of the distal one-third radius was measured by single-photon absorptiometry, lumbar spine and femoral neck were determined using dual-energy X-ray absorptiometry.
Measurements were repeated 6-monthly.
Baseline serum 25-hydroxycholecalciferol concentration and physical activity were also assessed.
The results confirm a positive effect of Ca on bone mass of the spine and radius but no effects on femoral-neck and height increase.
A longer trial is warranted to confirm a positive Ca effect during childhood that may modify future peak bone mass.
