ABSTRACT

OBJETIVO: Verificar a prevalência de risco de fratura estimada pela ultrassonometria óssea de calcâneo (UOC) em uma população de idosas e sua associação com fatores de risco. MÉTODOS: Estudo transversal com amostra selecionada aleatoriamente e submetida a questionário estruturado sobre fatores de risco para fratura e UOC. RESULTADOS: Foram estudadas 168 mulheres brancas, menopausadas, com média de idade de 69,56 ± 6,27 anos; 81 por cento da população de estudo tinha exame alterado, sendo 41 por cento consideradas de maior risco. As mulheres com exames alterados tinham menor peso, altura e IMC, e tinham menores valores de SOS, BUA, BQI e T-score. Após ajuste, o IMC manteve significância para UOC alterada (OR = 3,37, IC 1,19-9,56, p = 0,02) e a história prévia de fraturas para UOC da faixa de maior risco (OR = 4,44, IC 1,16-16,96, p = 0,03). CONCLUSÃO: Observamos alta prevalência de risco para fraturas determinado pela UOC, superior ao de outros estudos brasileiros, e sua associação com IMC e história prévia de fraturas.


OBJECTIVE: To verify the prevalence of women with risk of fractures estimated by ultrasonometry of the calcaneus (UOC) in a population of elderly women and its association with clinical risk factors. METHODS: Cross-sectional study of which sample was randomly selected and submitted to a structured questionnaire about risk factors for fractures. All women underwent UOC. RESULTS: We studied 168 Caucasian postmenopausal women, with a mean age of 69.56 ± 6.27 years; 81 percent of these women had abnormal test results and 41 percent of the abnormal results were considered higher risk. Women with abnormal test results had lower weight, height and BMI, and had lower values of SOS, BUA, BQI and T-score. After adjustment, BMI remained significant for abnormal UOC (OR = 3.37, 95 percent CI: 1.19 9.56, p = 0.02), and history of previous fractures for UOC of the higher risk range (OR = 4.44, 95 percent CI: 1.16-16.96, p = 0.03). CONCLUSION: We observed a high prevalence of risk of fractures determined by the UOC. Our prevalence was higher than those in other Brazilian studies. There was an association between UOC and BMI and previous history of fractures.
