Acceptability and compliance with hip protectors in community-dwelling women at high risk of hip fracture.

OBJECTIVES: To determine acceptability and compliance with hip protectors in women at high risk of hip fracture who are living independently in the community. METHODS: Women aged 65 yr and over referred for open access bone densitometry who had femoral neck osteoporosis and a high risk of falling were asked to wear hip protectors. RESULTS: Eighty five women fulfilled the inclusion criteria of whom 32 (38%) found the hip protectors acceptable and agreed to participate. Reasons given by the remaining 53 (62%) for not finding the hip protectors acceptable included discomfort on wearing, dislike of their personal appearance with the hip protectors on, and disagreement about their fracture risk. Participants were more likely to have a family history of osteoporosis (47 vs 26%, respectively) and hip fracture (16 vs 8%) compared with non-participants. At 12 months only about half of the subjects were wearing hip protectors daily. CONCLUSIONS: Our findings suggest that only a minority of community-dwelling women at high risk of hip fracture will wear hip protectors to reduce fracture risk. Their use should be restricted to highly motivated women who should be carefully identified.

Prevalence and causes of low bone density and fractures in kidney transplant patients.

Osteoporosis is known to occur in patients with kidney transplants, but limited information is available about the prevalence and causes of this complication. We asked all 330 patients with kidney transplants in our unit to participate in this study of whom 165 (50%) agreed to do so. The characteristics of the participating patients were similar to the remaining 165 nonparticipants. Seventy of 165 (42%) of the participants were women of whom 40 were postmenopausal in contrast to the men of whom only one was hypogonadal. Bone mineral density (BMD) was significantly reduced at the radius (Z score, -1.5) and femoral neck (Z score, -0.7), but the lumbar spine was normal. BMD was lower in women than men at all skeletal sites. Osteoporosis was found in 10-44% and osteopenia was found in 35-50% of women depending on the site. BMD was related inversely to time since transplantation and cumulative prednisolone dose. Twenty-seven of the 165 (16%) patients had either vertebral deformities or a history of a low trauma fracture after transplantation. This fracture group consisted of 10/27 (37%) men and 17/27 (63%) women, of whom 14 were postmenopausal. Fracture patients tended to be older and have a longer duration of renal failure, dialysis, transplantation, greater cumulative steroid dose, and higher bone resorption markers than the nonfracture group. No differences were found for cumulative doses of cyclosporin or tacrolimus. Logistic regression showed that only duration of dialysis and time since transplantation significantly increased fracture risk, with odds ratio (OR) for each year of dialysis or transplantation being 1.21 (CI, 1.00-1.48) and 1.14 (CI, 1.05-1.23), respectively. These data show that low bone density and fractures are common in patients with kidney transplant and are determined by both pre- and posttransplant variables. Fracture risk was greatest in women, particularly if they were postmenopausal and we recommend that this subgroup is targeted for assessment and treatment.

Detection of risk of falling and hip fracture in women referred for bone densitometry.

In an assessment of the practicality of measurement of fall-related risk factors for bone fracture, assessment was easy and the frequency of fractures was high enough to justify routine measurement.
