Low Fractional Calcium Absorption Increases the Risk for Hip Fracture in Women with Low Calcium Intake

Article Abstract:

Decreased ability to absorb calcium with age appears to increase the risk of hip fracture. This risk could be compounded by low dietary calcium intake. In a study of 5,452 women 69 years or older, 153 fractured their hip during a five-year follow-up. Women who had lower calcium absorption as measured by a three-hour isotope technique had a greater risk of hip fracture. The greatest risk occurred in women with low calcium absorption and low dietary calcium intake. These women had over twice the risk of hip fracture as women with adequate calcium absorption.

Bone mineral density and the risk of incident nonspinal fractures in Black and White women

Article Abstract:

A study was conducted to examine the association between bone mineral density (BMD) and incident nonspinal fractures in older African-American and white women. The result showed that African-American women have lower fracture risk than white women at every level of BMD.

Physical activity and osteoporotic fracture risk in older women

Article Abstract:

Higher levels of activity among older women may result in lower risk of osteoporotic hip fractures compared with sedentary women, but not necessarily wrist or vertebral fractures. In a study of 9,704 nonblack women 65 years and older living in various communities, very active women had significantly fewer hip fractures. One level of active women, but not all, had fewer vertebral fractures. It is possible that active women, when falling, put their hands out, thus fracturing the wrist while saving the hip from harm.
