El estudio se realizó sobre 133 mujeres jóvenes que consumían menos de 800 mg de calcio al día. De manera aleatoria, las participantes fueron divididas en dos grupos. Uno, medio, con dieta diaria de 1.000 a 1.100 mg de calcio. Otro, alto, con dieta de 1.200 a 1.300 mg de calcio al día. De total, 57 de las participantes utilizaban anticonceptivos oral y 76, no.
Entre las usuarias de anticonceptivos orales, la toma diaria de calcio previno la disminución de la densidad mineral ósea de la cadera y la columna.
Los autores consideran que hay que animar a las jóvenes, principalmente las usuarias de anticonceptivos orales, a un consumo diario de unos 1.000 mg de calcio a fin de prevenir problemas de la masa ósea.
