Osteoporosis: are calcium supplements before puberty justified?
Swiss authors have evaluated the effects on bone mineral density (BMD) of calcium supplements given to young pre-puberty girls. The first thing they noticed was that this "treatment" brought forward the age of the first period by several months!
Dr Thierry Chevalley in Lausanne, is the author of this study conducted on 144 little girls aged 8, who were studied for one year. He noted that the 67 children whose diet had been supplemented with calcium had their first periods an average of six months before the others.
However, he would not go quite so far as to say that these young girls had a better chance of building a quality bone structure than the others. Not yet in any case... "We must monitor this cohort for a few more years yet before drawing any final conclusions", he explained. Source: IOF - World Congress of Osteoporosis, Rio de Janeiro, 18 May 2004
