These results signify that all four dimensions of HRQOL represented by the BRFSS Core HRQOL Module are important predictors of both short-term and long-term adverse health events among older adults. This brief scale may be particularly useful for assessing the health of older adults in clinical settings and large-scale epidemiological studies.

Important gender differences and similarities in health were found using an unlike-sex twin design that reduced variability due to background characteristics. This design also minimized problems caused by gender differences in survival. Research on gender and health in older persons requires more detailed approaches to address the complexity of this topic.

Many older people use alcohol in combination with AI prescription drugs. Clinicians should warn every patient who is prescribed an AI drug about alcohol-drug interactions, especially those at high risk for concomitant exposure.

Objective. To examine the relationship between health-related quality of life (HRQOL) and health service use among older adults with osteoarthritis (OA). Methods. Subjects were 9,043 Medicare-enrolled survey respondents with a prior International Classification of Diseases, Ninth Revision code for OA. Analyses examined the relationship of 5 Centers for Disease Control and Prevention HRQOL items (general health, mental health, pain, activity limitation, and sleep) to physician visits, prescription analgesic or antiinflammatory use, and arthroplasty during 1 year of followup. Results. In analyses controlling for demographic and health-related variables, greater pain frequency was associated with increased odds of visiting a physician, using analgesic or antiinflammatory drugs, and having arthroplasty (P < 0.001). Poorer general health was associated with increased odds of analgesic or antiinflammatory use but decreased odds of arthroplasty (P < 0.01). More days of activity limitation and poor mental health were associated with decreased odds of analgesic or antiinflammatory use (P < 0.01). Conclusion. These HRQOL variables, especially pain frequency, can be valuable tools for estimating future health care use among older adults with OA.
