Dietary patterns and incident low-trauma fractures in postmenopausal women and men aged ≥ 50 y: a population-based cohort study.

Background: Previous research has shown that dietary patterns are related to the risk of several adverse health outcomes, but the relation of these patterns to skeletal fragility is not well understood.

Objective: Our objective was to determine the relation between dietary patterns and incident fracture and possible mediation of this relation by body mass index, bone mineral density, or falls.

Design: We performed a retrospective cohort study based on the Canadian Multicentre Osteoporosis Study-a randomly selected population-based cohort.

Health-related quality of life in Canadian adolescents and young adults: normative data using the SF-36.

Objectives: Normative data for the SF-36 measure of health-related quality of life (HRQOL) exist for those over 25 years of age, based on data from the population-based Canadian Multicentre Osteoporosis Study (CaMos). CaMos recently recruited a sample of young Canadians aged between 16 and 24 years. The purpose of this study was to develop normative SF-36 data for this age group.

Dietary patterns in Canadian men and women ages 25 and older: relationship to demographics, body mass index, and bone mineral density.

Background: Previous research has shown that underlying dietary patterns are related to the risk of many different adverse health outcomes, but the relationship of these underlying patterns to skeletal fragility is not well understood. The objective of the study was to determine whether dietary patterns in men (ages 25-49, 50+) and women (pre-menopause, post-menopause) are related to femoral neck bone mineral density (BMD) independently of other lifestyle variables, and whether this relationship is mediated by body mass index.

Methods: We performed an analysis of 1928 men and 4611 women participants in the Canadian Multicentre Osteoporosis Study, a randomly selected population-based longitudinal cohort.

Calcium and vitamin D intakes in an adult Canadian population.

Purpose: Calcium and vitamin D intakes from food and supplements were estimated in Canadian men and women.

Methods: Calcium intakes from both diet and supplements and vitamin D intakes from fortified milk and supplements were estimated using cross-sectional data from 9423 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.

The association between body mass index and health-related quality of life: data from CaMos, a stratified population study.

Background: Deviation from normal weight is associated with health risks, but less is known about the association between weight and health-related quality of life (HRQOL). We investigated this in the context of a population-based study, using a standard five-category weight classification system based on body mass index (BMI).

Methods: The Canadian Multicentre Osteoporosis Study is a randomly selected sample of men and women over 25 years of age from nine centres across Canada.

Changes in body mass index in Canadians over a five-year period: results of a prospective, population-based study.

Background: The initiation of the Canadian Multicentre Osteoporosis Study in 1996, and subsequent follow-up of the cohort 5 years later, provided longitudinal body mass index (BMI) data for a random sample of Canadians.

Methods: Height and weight were measured at baseline and 5 years and used to calculate BMI and assign one of six weight categories. Multiple imputation was used to adjust for missing weight at year 5.

Stability of normative data for the SF-36: results of a three-year prospective study in middle-aged Canadians.

Background: The SF-36 is widely used to assess health-related quality of life (HRQOL), but with few longitudinal studies in healthy populations, it is difficult to quantify its natural history. This is important because any measure of change following an intervention may be confounded by natural changes in HRQOL. This paper assesses mean changes in SF-36 scores over a 3-year period in men and women between the ages of 40 and 59 years at baseline.

Is there regional variation in the SF-36 scores of Canadian adults?

Background: Canadian normative data for the Medical Outcomes Study 36-item short form (SF-36) have recently been published. However, there is evidence from other countries to suggest that regional variation in health-related quality of life (HRQOL) may exist. We therefore examined the SF-36 data from nine Canadian centres for evidence of systematic differences.
