Osteoporosis and health-related quality of life (SF-36) in elderly people - ISACAMP 2008
METHODS: It is a population-based, cross-sectional study, which used data from the ISACamp/2008. This study examined the population of 60 years of age or older, totaling 1,432 elderly people. The dependent variables were the 8 domains of the SF-36, version 2. The main independent variables were self-reported osteoporosis and limitation in daily life activities, resulting from osteoporosis. Analyses were performed with the simple and multiple linear regression models, using the svy command of the Stata 11.0.
RESULTS: The prevalence of osteoporosis was 14.9%. The elderly people reported with osteoporosis showed significant associations in all domains of the SF-36, compared to those without osteoporosis. Women were those who most suffered the impact of the disease on the HRQL, showing significant associations in all domains of the SF-36. The domains of role physical and body pain were the most affected for both sexes, after adjusted by age and comorbidities. Older individuals, with lower education and who had reported osteoporosis, also showed low scores in most domains of the SF-36, when compared to youngers and with better education. Considering those who reported limitations of usual activities, lower scores were evidenced mainly in the domains of functioning physical, role physical and body pain.
CONCLUSIONS: Osteoporosis is a disease that causes significant limitations in the lives of the elderly people, being associated with poorer health and quality of life, by losses in functioning physical, role physical and body pain.
