Relationship between long-term calcium intake and bone mineral content of children aged from birth to 5 years

摘要: This study evaluated Ca intake in Hong Kong Chinese children and examined the association between long-term bone mineral content (BMC) children. Longitudinal dietary from birth to 5 years was obtained 128 (sixty-seven boys, sixty-one girls). intakes were by history cross-checked with food frequency 24 h recall. At age BMC determined at one-third distal radius of right arm using single-photon absorptiometry. The mean 133 546 (SD 325) mg/d. Milk chief source (43·5 %). From years, 90 % had been taking milk regularly. width (BW) these 0·317 0·042) g/cm 0·756 0·074) cm respectively. not correlated current Ca, energy protein but positively weight (r 0·57), height 0·47) BW 0·66).
