The study was conducted to investigate the association between nutrient intakes and change of bone mineral contents (BMC) among early pubertal aged girls. Two hundred and thirty girls between 9 to 11 years of age participated in four surveys over 2 year period. During each survey, dietary intakes were collected with 3-day food records and BMC of left leg's calcaneus were measured PIXI(Lunar Ltd.). Body composition was measured by bioimpedance method. Mean values of BMC increased in consecutive measurements -- 1.48g, 1.54g, 1.61g and 1.66g. The change of BMC between the first and last measurements was significantly correlated with age, % body fat, BMC at the baseline and mean isoflavone intake (p<0.05). In stepwise regression of BMC change, protein, Vit.C, Fe and Vit.B6 were significant explanatory variables(R²=0.25, p<.001, F=14.89) after adjusting for age, % body fat and BMC at baseline. The results imply that the change of BMC among early pubertal aged girls may be affected by intakes of certain nutrients. [ABSTRACT FROM AUTHOR]
