Osteoporosis - Epidemiology

Studies that relate to population-based data on osteoporosis prevalance and incidence

Bone status and adipokine levels in children on vegetarian and omnivorous diets.

BACKGROUND & AIMS: Measurements of bone mineral density (BMD) reflect bone status but not the dynamics of bone turnover. Biochemical markers, which show global skeletal activity, were validated for the assessment of bone formation and resorption processes. Adipokines also play a significant role in the regulation of bone metabolism.
OBJECTIVE: To assess body composition, bone mineral density, bone turnover markers and adipokine levels in relation to vegetarian and omnivorous diets.

Long-term Low Intake of Dietary Calcium and Fracture Risk in Older Adults with Plant-Based Diet: A Longitudinal Study from the China Health and Nutrition Survey.

KEYWORDS:
China Health and Nutrition Survey; dietary calcium; epidemiological study; fracture prevention; plant-based diet

Milk intake and risk of mortality and fractures in women and men: cohort studies.

OBJECTIVE: To examine whether high milk consumption is associated with mortality and fractures in women and men. DESIGN: Cohort studies. SETTING: Three counties in central Sweden. PARTICIPANTS: Two large Swedish cohorts, one with 61 433 women (39-74 years at baseline 1987-90) and one with 45 339 men (45-79 years at baseline 1997), were administered food frequency questionnaires. The women responded to a second food frequency questionnaire in 1997.

Long-term vegetarian diet and bone mineral density in postmenopausal Taiwanese women.

This study examined bone density among postmenopausal Buddhist nuns and female religious followers of Buddhism in southern Taiwan and related the measurements to subjects characteristics including age, body mass, physical activity, nutrient intake, and vegetarian practice. A total of 258 postmenopausal Taiwanese vegetarian women participated in the study. Lumbar spine and femoral neck bone mineral density (BMD) were measured using dual-photon absorptimetry.

Spinal bone mineral density in premenopausal vegetarian and nonvegetarian women: cross-sectional and prospective comparisons.

OBJECTIVE:To compare spinal bone mineral density (BMD) and 1-year BMD change between premenopausal vegetarian and nonvegetarian women. DESIGN:Cross-sectional comparison of spinal BMD at baseline and prospective comparison of a subsample. SETTING:A western Canadian metropolitan area. SUBJECTS/SAMPLES:Healthy vegetarian (n = 15 lacto-ovo-vegetarian, n = 8 vegan) and nonvegetarian (n = 22) women aged 20 to 40 years, with regular menstrual cycles and stable body weight completed baseline measurements.

[Osteoporosis and phytoestrogens: an assessment of bone mineral density via quantitative peripheral computed tomography in milk-egg-vegetarian women in the premenopause].

PURPOSE:Noninvasive assessment of bone mineral density, geometrical and biomechanical properties in premenopausal women with dietary intake of phytoestrogens and comparison of these parameters with those of age-matched female subjects with "Mediterranean" dietary intake lacking in these substances. MATERIAL AND METHODS:Volumetric cortical, trabecular and total mineral density and bone geometrical properties were evaluated in 15 female subjects with phytoestrogens dietary intake.
