“…While some studies reported no significant influence of age on BMD within this age range [22, 23], other studies have shown an inverse correlation between age and BMD at the lumbar spine, femoral neck, and forearm [24], or a direct correlation between age and lumbar spine BMD [25, 26] and a negative correlation at the femoral neck [26]. Additionally, the age at which peak BMD is reached may differ between sites and different populations [27–30]. Body weight [31–33] and BMI [31, 34, 35] are strong predictors of BMD.…”

Weight-bearing and resistance physical activities are recommended for osteoporosis prevention, but it is unclear whether an intensity level above current recommendations has a positive effect on adult premenopausal women. Body composition and bone mineral density (BMD) by DXA were compared in three groups of women as follows: Sedentary, Maintenance exercise, and federated Sport Team (n = 16 for each group). Physical activity was estimated from the International Physical Activity Questionnaire (IPAQ). The groups did not differ in age, height, weight, or body mass index. Bone mineral content and non-fat soft tissue mass were higher and fat mass was lower in the Sport Team group than in the other groups. The same was true for BMD of total skeleton, lumbar spine, femoral neck, and total hip. A test for linear trend of body composition and BMD showed significant results when including all three groups. Simple and multiple regression analyses showed significant associations between physical activity level (or alternatively, years of participation in programmed physical activity) and bone mass measures at all sites except for the middle third of radius. It is concluded that a level of physical activity higher than that usually recommended benefits bone health in adult premenopausal women.

“…Esses dados são consis-tentes com o diagnóstico de osteoporose segundo os critérios adotados pela World Health Organization 12 e enfatizam o alto risco de fraturas nessa população. Estudos anteriores observaram também associação entre peso corporal e DMO, tanto na coluna como no colo do fêmur 16,17 . Além disso, outro importante estudo também identificou associação entre idosos com baixo peso corporal e osteoporose nas regiões do colo do fêmur e quadril total, com T-score de -3 e -2,7, respectivamente 18 , demonstrando a influência do peso corporal na massa óssea.…”

Força muscular e densidade mineral óssea em idosos eutróficos e desnutridos

et al. 2011

Este estudo teve como objetivo avaliar a associação do estado nutricional com a força muscular de preensão manual e a densidade mineral óssea em idosos do sexo masculino. MétodosParticiparam do estudo 41 idosos do sexo masculino, sendo 20 eutróficos (peso: M=69,6, DP=8,4; índice de massa corporal: M=25,7, DP=2,2) e 21 desnutridos (peso: M=50,9, DP=6,1; índice de massa corporal: M=18,7, DP=1,8), classificados subjetivamente segundo a Mini Avaliação Nutricional. A avaliação antropométrica incluiu peso corporal, altura, circunferência do braço e da panturrilha. A composição corporal foi avaliada pelo método de absorciometria por dupla emissão de Raios X, e a ocorrência de osteoporose foi definida de acordo com os critérios estabelecidos pela Organização Mundial da Saúde. A força muscular foi avaliada pelo dinamômetro de mão. ResultadosO grupo desnutrido apresentou valores expressivamente menores dos parâmetros antropométricos e de composição corporal em relação ao grupo eutrófico (p<0,005). Além disso, a ocorrência de osteoporose foi significativamente maior (p<0,01) no grupo desnutrido em todas as regiões estudadas: colo do fêmur, quadril total e coluna. A força muscular de preensão manual dos idosos desnutridos foi significativamente menor que a dos idosos eutróficos (M=23,1, DP=6,8 e M=30,3, DP=8,4, respectivamente; p<0,005).

“…The subject has been recently reviewed [3]. A short number of reports dealing with bone mass measurements [4][5][6][7][8][9][10][11][12] and thefrequency of osteoporotic fractures [13][14][15][16][17] in relatively limited areas and populations will be reviewed here. Tables 2-4 and Figs.…”

“…Tables 2-4 and Figs. 1-3 summarize the results reported from Buenos Aires, San Pablo and Bogotä [6,7,9,11,12] on the bone mineral density (BMD) of the lumbar spine, femoral neck and total skeleton obtained by dual-energy X-ray absorptiometry (DXA) in normal women. The same type of equipment was used in the four studies (DPXL).…”
