Abstract

Purpose: Calcium and vitamin D intakes from food and supplements were estimated in Canadian men and women.
Methods: Calciumintakes fromboth diet and supplements and vitamin D intakes fromfortifiedmilk and supplements were estimated using cross-sectional data from9423 randomly selected subjects aged 25 years or older, who were participating in a longitudinal study on osteoporosis. Subjects completed an abbreviated food frequency questionnaire administered by a trained interviewer between July 1995 and December 1997.
Results: Themean (standard deviation) daily intake for calciumwas estimated to be 1038 (614)mg for women and 904 (583)mg formen; for vitamin D,mean intakes were 5.6 (5.9) μg and 4.8 (5.5) μg for women andmen, respectively.
Conclusions: Mean intakes for calcium and vitamin D in men and women under age 51 were close to the adequate daily intake levels. Older adults, however, may be at risk of deficiency.

Résumé

Objectif: Les apports en calcium et vitamine D provenant de l'alimentation et des suppléments ont été évalués chez des Canadiens et Canadiennes.
Méthodes: Les apports en calciumprovenant tant de l'alimentation que des suppléments et les apports en vitamine D provenant du lait enrichi et des suppléments ont été estimés à l'aide de données transversales de 9423 sujets de 25 ans ou plus choisis au hasard, qui participaient à une étude longitudinale sur l'ostéoporose. Entre juillet 1995 et décembre 1997, les sujets ont rempli un questionnaire abrégé de fréquence alimentaire administré par un intervieweur entraîné.
Résultats: L'apport quotidienmoyen (écart type) de calcium a été estimé à 1038 (614)mg chez les femmes et à 904 (583)mg chez les hommes; pour la vitamine D, les apportsmoyens se chiffraient à 5,6 (5,9) μg et 4,8 (5,5) μg respectivement pour les femmes et les hommes.
Conclusions: Les apports moyens en calcium et en vitamine D chez les hommes et les femmes de moins de 51 ans étaient proches des apports quotidiens suffisants. Cependant, les adultes plus âgés peuvent se trouver à risque de carence.
