Influence of body composition on the bone mass of postmenopausal women

OBJETIVO: Investigar a influência do peso corporal (PC), massa gorda (FM) e massa magra (LM) na densidade mineral óssea (BMD) de várias regiões do esqueleto. PARTICIPANTES: Sessenta e uma mulheres brancas na pós-menopausa (50.1±4.8 anos). MENSURAÇÃO: Medida do BMD através da densitometria duo-energética. Os resultados foram analisados através de regressão linear e os slopes de cada curva foram comparados. RESULTADOS: Mostraram que as correlações PC-, FM- e LM-BMD foram positivas, enquanto que as correlações idade- e anos de climatério-BMD foram negativos. LM foi o principal fator que influenciou o BMD em quase todas as regiões ósseas. CONCLUSÃO: FM e LM apresentam efeito positivo no BMD, entretanto, LM é o principal determinante da massa óssea. Além do mais, maiores valores de LM e FM têm um efeito protetor na diminuição do BMD decorrente da menopausa. Portanto, mulheres no climatério com baixo PC, especialmente, baixo LM apresentam maior risco de desenvolver osteoporose.
