Abstract

Relatively little is known about the factors in Canada which lead to osteoporosis and its concomitant fractures. The Canadian Multicentre Osteoporosis Study (CaMos) is a prospective cohort study which will estimate the incidence and prevalence of declining bone mass and fractures. The impact of osteoporosis in Canada will be assessed, including regional variation and the effect of various risk factors. The study will provide information for developing prevention programs. The cohort has been drawn from a random population-based sample of non-institutionalized men and women 25 years old or more and living within 50 km. of nine cities in Canada. Through telephone interviews 9,423 participants have been recruited. All answered an extensive questionnaire, and had physical measurements related to bone quality taken. This paper details the CaMos baseline and five-year follow-up protocol.

Résumé

On en sait relativement peu sur les facteurs au Canada qui entraînent l'ostéoporose et ses fractures concomitantes. L'étude canadienne multicentrique sur l'ostéoporose (CaMos) est une étude prospective par cohorte qui évaluera l'incidence et la prévalence de la perte de la masse osseuse et des fractures. Les répercussions de l'ostéoporose au Canada seront évaluées, en tenant compte de la variation régionale et les conséquences des divers facteurs de risque. L'étude fournira de l'information en vue d'élaborer des programmes de prévention. La cohorte est constituée d'un échantillon de population choisi au hasard d'hommes et de femmes non-institutionnalisés, âgés de 25 ans ou plus, qui habitent dans un rayon de 50 km. de neuf villes canadiennes. 9423 sujets ont été recrutés par des entrevues téléphoniques. Tous les participants ont répondu à un questionnaire approfondi et se sont soumis à des mesures de la qualité osseuse. Cet article fournit les détails de base de CaMos ainsi que le protocole suivi de cinq ans.
