We conducted a cross-sectional study including 1871 women that performed scans between January and December 2012. We conducted a logistic regression analysis with all independent variables and outcomes (osteopenia, osteoporosis and fracture risk). According to DXA results, 36.5% of women had normal BMD, 49.8% were diagnosed with osteopenia and 13.7% with osteoporosis. Menopause and age over 50 years old were risk factors for osteopenia and osteoporosis while prior hysterectomy and BMI greater than 25 were protective factors. For the outcome of fracture at any site the risk factors were age over 50 years old, osteopenia and osteoporosis (OR = 2.09, 95% CI: 1.28-3.40) and (OR = 2.49, 95% CI: 1.65-3.74), respectively. Fatores associados à osteopenia e osteoporose em mulheres submetidas à densitometria ósseaPalavras-chave: Osteoporose Densitometria Epidemiologia Doenças ósseas metabólicas r e s u m o O objetivo deste estudo foi determinar a prevalência de osteopenia e osteoporose em uma população de mulheres que fizeram exames de densitometria em uma clínica especializada no sul do Brasil. Nós conduzimos um estudo transversal, incluindo 1.871 mulheres que se submeteram à densitometria óssea entre janeiro e dezembro de 2012. Foi feita uma análise de regressão logística com todas as variáveis independentes e os desfechos (osteopenia, osteoporose e risco de fraturas). A densitometria óssea foi diagnosticada como normal em 36,5% das mulheres, 49,8% com osteopenia e 13,7% com osteoporose. Estar na menopausa 224 r e v b r a s r e u m a t o l . 2 0 1 5;5 5(3):223-228 e ter mais de 50 anos foram fatores de risco para osteopenia e osteoporose, enquanto ter feito histerectomia e apresentar índice de massa corporal (IMC) maior do que 25 foram fatores de proteção. Para o desfecho fratura em qualquer sítio, os fatores associados foram idade acima de 50 anos e osteopenia ou osteoporose, (OR = 2,09, intervalo de confiança [IC]:1,28-3, 95%, 40) e (OR = 2,49, 95% CI: 1,65-3, 74), respectivamente.
