  1. Dietary calcium and bone density in adolescent girls and young women in Europe.

    Article - En anglais

    The objective of this study was to investigate the association between dietary calcium intake and radial bone density among young women, over the whole range of intake and at different levels of calcium intake.

    The study design was a cross-sectional, observational multicenter investigation in six European countries.

    One thousand one hundred and sixteen healthy Caucasian girls aged 11-15 years and 526 women aged 20-23 years participated, after having been selected from larger population samples to represent a large range in calcium intake.

    Bone mineral density (BMD) was measured with dual-energy X-ray absorptiometry at the ultradistal and middistal radius.

    Calcium intake was assessed with 3-day food records.

    Other potential determinants of BMD were measured by anthropometry or questionnaires.

    Mean calcium intake among the girls varied between 609 mg/day in Italy and 1267 mg/day in Finland ; intakes for women were in a similar range.

    After adjustment for height, weight, and age at menarche for the women, and adjustment for age, height, weight, Tanner stage, and bone area for the girls, radial BMD at both sites did not significantly vary among quartiles of calcium intakes for both age groups.

    In multivariate linear regression, calcium was weakly positively associated with BMD at both sites in the girls (per 100 mg of calcium : bêta=0.57 mg/cm2, p=0.03 for middistal BMD and bêta=0.56 mg/cm2, p=0.01 for ultradistal BMD). (...)
