Avaliação dos fatores de risco para baixa massa óssea em mulheres pós-menopáusicas de um serviço de diagnóstico

Abstract

Changes in bone mass in women are both determined by genetic and environmental factors. The most significant bone loss occurs around menopause. Objectives: Evaluate the prevalence of low bone mass and of the associated risk factors of in postmenopausal women. Methods: Review of medical records of postmenopausal women bone densitometry of lumbar spine and hip done at the Centro de Diagnóstico da Unimed Porto Alegre, Brasil in the period of June 2011 to November 2011, in a retrospective study. This study assessed bone mineral density, anthropometric data, clinical history and risk factors for low bone mass. The information was obtained before the time of the test. Results: 716 postmenopausal women met the criteria of the study .Most women were Caucasian 676 (97.5%), average 61.45 years old, had BMI of 26.25 kg / m², menarche at 12.9 years old and menopause at 48.4 years old. 304 (42.6%) of the women were 55-64 years old. 293 (41%) women had average BMI. More than half of the sample 388 (54.2%) subjects had osteopenia and among the regions of interest, the lumbar spine showed 401 (56.6%) subjects with osteopenia and 154 (21.7%) with osteoporosis. 254 (46,3%) women were eutrophic and had low bone mass. Conclusion: when the sample of postmenopausal women was evaluated by bone densitometry there was a higher than expected occurrence of low bone mass and therefore associated risk factors for fractures.
