摘要
用单光子吸收仪测量5岁儿童(115名江门市儿童和128名香港儿童)桡骨远端1/3处骨矿物质含量(MBC)。江门市和香港儿童钙平均摄入量分别为244±46及542±332mg/d。江门市儿童骨矿物质含量、体重和身高均明显低于香港儿童的相应数值,分别低14%、10%和4%(P<0.001)。经多元回归分析调整后,骨矿物质含量的地区差异仍是0.0303g/cm。比较两地低钙摄入量的5岁儿童骨矿物质含量,江门市儿童骨矿物质含量同样明显低于香港儿童(P<0.003)。本研究结果提示。
one mineral content(BMC)of 5-year-old Chinese
children (l15 chil-dren in Jiangmen,and l28 children in Hong Kong) was evaluated by
sin-gle-photon absorptiometry at the distal l/3 radius.The M±SD calcium intakes of Jiangmen
and Hong Kong were 224±46 and 542 ±332 mg/d,respectively. The mean BMC, weight and
height of Jiangmen children were significantly less than Hong Kong children by 14%,10%,and
4%, respectively(P<0.00l).A regional difference in BMC of 0.0303g/cm(P<0.000])still remained
after adjusting for bone width and weight by mul-tiple regression analysis. Comparing
sub-groups of children in the two re-gions with comparable low current calcium intake at 5 years,
the BMC of Jiangmen children was still significantly lower thaii that of Hong Kong children
(P<0.003),The study suggests that the regional discrepancy in BMC might be explained by
long-term habitual calcium intake and physical activity.
