RESUMO
Pós-menopausa é período de maior perda óssea e faz-se necessário instituir medidas preventivas que amenizem sua progressão. Objetivo: correlacionar o escore da densidade mineral óssea (DMO) e seus fatores de risco, buscando determinar aqueles que mais a influenciam. Método: estudo transversal, descritivo de 62 mulheres na pós-menopausa, saudáveis, idade média de 56,82 ± 4,02 anos, avaliadas quanto aos fatores de risco para osteoporose e nível de atividade física. Absorção de dupla energia de raios-X (DXA) avaliou coluna lombar e fêmur proximal. Os grupos, DMO normal e diminuída, foram analisados pelos testes T de Student, qui-quadrado e correlações. Resultados: Mulheres com menor índice de massa corporal (IMC), maior idade e maior tempo de menopausa apresentaram menor DMO em fêmur. Raça negra e ausência de história familiar correlacionaram-se com maior DMO. Conclusão: IMC, idade, peso, história familiar de osteoporose, raça e tempo de menopausa foram os principais fatores determinantes da DMO em mulheres na pós-menopausa.
Post-menopause is the period of greatest bone loss and it is necessary to introduce preventative measures to mitigate its progression. Aim: compare the score of bone mineral density (BMD) and their risk factors and to determine those most influencing. Method: Cross-sectional, descriptive study of 62 postmenopausal women, healthy, average age 56.82 ± 4.02 years, evaluated for risk factors for osteoporosis and physical activity level. Absorption dual energy X-ray absorptiometry (DXA) evaluated lumbar spine and proximal femur. Groups, normal and reduced BMD were analyzed by Students t test, chisquare and correlations. Results: Women with lower body mass index (BMI), older age and longer duration of menopause had lower BMD at the femur. Black race and absence of family history correlated with higher BMD. Conclusion: BMI, age, weight, family history of osteoporosis, race, and time since menopause were the main determinants of BMD in postmenopausal women.

BACKGROUND: We aimed to discuss the risk assessments for both patients with hip fractures due to fall-related, low energy traumas and non-fractured control patients by examining bone mineral density and genetic data, two features associated with femoral strength and hip fracture risk. METHODS: Twenty-one osteoporotic patients with proximal femur fractures and non-fractured, osteoporotic, age- and gender-matched controls were included in the study. Bone mineral density measurements were performed with a Lunar DXA. The COL1A1, ESR, VDR, IL-6, and OPG genes were amplified, and labeling of specific gene sequences was performed in a multiplex polymerase chain reaction using the osteo/check PCR kit from the whole blood of all subjects. RESULTS: The bone mineral density (trochanteric and total bone mineral density values) of the fracture group was significantly decreased relative to the control group. We were not able to conduct statistical tests for the polymorphisms of the COL1A1, ESR, and VDR genes because our results were expressed in terms of frequency. Although they were not significant, we did examine differences in the IL-6 and OPG genes polymorphisms between the two groups. We concluded that increasing the number of cases will allow us to evaluate racial differences in femoral hip fracture risk by genotypes.
