“…According to Rodrigues-Filho et al, 1 maintenance of bone mineral density (BMD) is very important to prevent osteoporosis, which is characterized by an imbalance between the activity of the osteoblastic and osteoclastic cells; in other words, the matrix and the bone minerals are lost due to excessive bone resorption in comparison with formation.…”

Objective:To evaluate the association between bone mineral density (BMD) and body composition in healthy older adults at different skeletal sites. Methods:We analyzed 87 medical records and BMD along with the body composition of men ranging from 60 to 87 years of age (mean: 68.5, standard deviation: 6.5). Inclusion criteria were normal BMD values (T-score greater than or equal to -1.0) and body mass index within normal or overweight range (18.5 to 29.5 kg/m2). Body composition was evaluated using bone densitometry with dual-energy X-ray absorptiometry (DEXA) in a LUNAR-DPX apparatus. Results:Greater lean mass, fat mass, and soft tissue was associated with better BMD values in older adults, and higher age was associated with poorer BMD. Conclusion:Body composition (lean and fat masses and soft tissue) in older men is positively associated with BMD at all body sites (arms, legs, and trunk). Level of Evidence II; Prognostic studies - Investigating the effect of a patient characteristic on the outcome of disease.

“…The comparative contribution of the body fat and LM (or fat-free mass) to BMD variation has been controversial based on the original research findings available. Some studies 12–14 have reported that LM, not FM, is associated with bone mass, whereas others 5 , 15 have found that FM, not LM, is important in the determination of BMD. Whereas some have indicated that both FM and LM can equally serve as a predicting factor for BMD.…”

Owing to conflicting results of the association between body composition and bone mineral density (BMD), we investigated the relationship between fat mass (FM), lean mass (LM), and BMD in New Zealand postmenopausal women. We hypothesized that increased LM will indicate a higher BMD. A cross-sectional study was performed examining the associations between body composition, anthropometric measures, activity energy expenditure, and bone health status (using dual-energy X-ray absorptiometry [DXA]). A total of 127 healthy postmenopausal women aged between 54 and 81 years. Both FM and LM were significantly associated with BMD at all sites. However, LM, not FM, was the strongest predictor of femoral neck (FN) BMD (β = 0.497, p < 0.001), hip BMD (β = 0.495, p < 0.001), spine BMD (β = 0.449, p < 0.001), and whole body BMD (β = 0.406, p < 0.001). Age was negatively associated with FN and hip BMD. LM was positively associated with FN, spine, hip, and whole body BMD. Our findings suggest the need to increase LM rather than FM highlighting the importance of physical activity for this age group.

“…O IMC correlacionou-se positivamente com a DMO, sendo os pacientes com osteoporose apresentavam um IMC significativamente menor do que aqueles com osteopenia. Esses dados são concordantes com a literatura [26][27][28][29] , que indica que o excesso de peso, tanto devido a gordura corporal como pelos músculos esqueléticos, estimula a osteogênese ao exercer força mecânica sobre os ossos [30][31] .…”

Introdução: A vitamina D e o paratormônio (PTH) são os principais moduladores do metabolismo mineral, contribuindo para homeostase do cálcio e fósforo. Considera-se como insuficientes níveis séricos abaixo de 30 ng/mL de 25-hidroxi-vitamina D [25(OH)D] e deficientes quando abaixo de 20 ng/mL. Tal deficiência também ocasiona aumento da secreção de PTH e, assim, há aumento da desmineralização óssea. Este estudo visa avaliar os níveis séricos de 25(OH)D em mulheres na pós-menopausa e correlacioná-los com as concentrações de PTH e a densidade mineral óssea (DMO). Materiais e métodos: Foram coletados dados clínicos, laboratoriais e densitométricos de 114 mulheres na pós-menopausa que participaram de estudo clínico prévio. As pacientes incluídas apresentavam diagnóstico de osteopenia ou osteoporose sem tratamento prévio. A análise estatística foi realizada pelo software Statistica - Statsoft®. Resultados: As pacientes foram classificadas em osteoporóticas 82,9% (n=92) e osteopênicas 17,1% (n = 19). A média dos valores de 25(OH)D encontrada foi 26,21 ± 9,69 ng/mL. Identificou-se deficiência (16,05 ± 2,81 ng/mL) em 32,4% das pacientes (n = 37) e insuficiência (24,71 ± 3,18 ng/mL) em 33,3% (n = 38). Os valores de PTH apresentaram média de 53,7 ± 20,1 pg/mL. Destes, 25% (n = 29) apresentaram-se acima dos valores de referência. Os valores séricos de PTH correlacionaram-se negativamente com os valores séricos de 25(OH)D (p < 0,01; rho = -0.2971). Houve uma correlação negativa do T-score de colo de fêmur em duas situações: histórico de fraturas e no diagnóstico de fraturas de coluna (p < 0,01). Conclusão: Neste grupo de mulheres pós-menopausadas houve uma alta prevalência de hipovitaminose D, a qual se correlacionou negativamente com o PTH, não sendo observado relação com as estações do ano. Houve uma correlação entre a história de fraturas e a DMO, evidenciando que a DMO de fêmur pode predizer risco de fraturas em outros sítios.
