Our data indicate that low BMD and independence in transfer are significant predictors of osteoporotic fracture in white female nursing home residents. JAMA. 2000;284:972-977

The psychosocial effects of facial acne are well accepted but until recently few validated instruments existed which were suitable for use in clinical trials. The aim of this study was to assess measurement characteristics (reproducibility, correlation with acne severity, and sensitivity to detect change after acne therapy) of a new acne-specific quality of life instrument, the Acne-QoL. We found that the Acne-QoL is reliable, valid and able to distinguish differences across severity groups and improvement over 16 weeks of standard therapy. The use of the Acne-QoL should aid physicians in understanding the impact of facial acne on young adults, and may be useful in assessing therapeutic effects in acne clinical trials.

This study describes the prevalence of osteoporosis in a statewide sample of nursing home residents. Composite forearm bone mineral density (BMD) (including the distal radius and the distal ulna) of 1475 residents aged 65 years and older from 34 randomly selected, stratified nursing homes was assessed. BMD was expressed with reference to World Health Organization diagnostic criteria. Trends with age, gender and race were consistent with other populations. However, prevalence estimates were higher than community-based age-specific rates. The prevalence of osteoporosis for white female residents increased from 63.5% for women aged 65-74 years to 85.8% for women over 85 years of age. Only 3% had composite forearm BMD within 1 standard deviation of the young adult mean. The significance of the high prevalence of low BMD in nursing home residents is the increased fracture risk it may confer. In community cohorts of white women, the risk of hip fracture increases approximately 50% for every 1 standard deviation decrease in bone mass. However, the degree to which BMD contributes to fracture risk in this population has not been well established.

We report the development and validation of an osteoporosis-targeted quality of life questionnaire to measure the impact of the disease in the general population. From multiple focus groups with women with osteoporosis, healthy women at risk for osteoporosis, spouses and relatives of women with osteoporosis, and health care providers, we identified over 300 potential items related to the disease. A lengthy questionnaire incorporated these items and was administered to a second large study cohort of 222 women with clinical osteoporosis (history of fracture, significant height loss, and/or kyphosis); 101 women with known low bone mineral density levels that would categorize them as osteoporotic but who had not yet shown obvious physical manifestations of the disease; and 142 women with other conditions (such as arthritis, cancer, depression) expected to also have an impact on quality of life. Final items from among the original 300 were chosen for their demonstrated relationship with osteoporosis as measured by clinical manifestations and low bone density and with quality of life measured by a standard generic questionnaire, the SF-36. The final questionnaire contains 26 scored items in three domains-physical activity, adaptations, and fears-and six nonscored questions relating to osteoporotic changes and diagnosis. This instrument is unique among osteoporosis-targeted questionnaires in that it attempts to measure the total impact of the disease on quality of life within a population at a single point in
