Abstract:
Abstract Few studies exist evaluating fracture prediction in women aged 50-59. Clinical risk factors are important determinants for fracture prediction in younger postmenopausal women since most fractures occur outside the range of an osteoporotic bone mineral density. Although fracture incidence rates in this age group are about one-half of those aged 60-69, considerable costs and loss of quality-adjusted life years are still incurred in this age group. We sought to determine what clinical risk factors would predict subsequent fractures. Questionnaires were mailed out to 546 rural women who underwent osteoporosis screening 8.3 years previously by bone densitometry and a 24-item clinical risk factor assessment. Our survey had a 55% response rate and found that 11.9% of respondents had subsequent fractures. A prior fracture history, self-reported rheumatoid arthritis, and menopause age <40 were significantly associated with subsequent fractures. A logistic regression analyses showed only a prior fracture history and menopause age

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
