several demographic factors may be considered as barriers to osteoporosis prevention like high rate of illiteracy and low socioeconomic status in developing countries, there is lack of studies that assess the relationship between socioeconomic status and osteoporosis. this study was a case-control study and it was conducted in two bone mineral density centers in tehran. case group includes 163 ...

The association between hip fracture and reduced bone mineral density is well documented, with reduced bone mineral density predisposing to fracture. However, it is unknown whether an association exists between the magnitude of bone density lost and the severity of the hip fracture sustained. One hundred forty-two patients (96 women, 46 men) with a mean age of 74 years (range, 49-92 years) who ...

We searched for key genes that could accurately predict bone mineral density. The gene expression profile GSE7429 was downloaded from the Gene Expression Omnibus database, which includes 20 samples, 10 with high and 10 with low bone mineral density. The differentially expressed genes (DEGs) were identified with packages in R language. Further, BLASTX was used to obtain COG function classificati...

UNLABELLED We provide the first reference values for bone mineral content and bone mineral density according to age and sex in Iranian children and adolescents. The prevalence of hypovitaminosis D was high, and levels of physical activity were low in our sample. Multiple regression analyses showed age, BMI, and Tanner stage to be the main indicators of bone mineral apparent density. PURPOSE N...

INTRODUCTION Osteoporosis and vitamin B12 deficiency are conditions with an increasing prevalence over time. It has been described an association between low serum vitamin B12, osteoporosis and increased risk of bone fractures, but the studies are heterogeneous and the results are controversial. OBJECTIVE To investigate the association between plasma levels of vitamin B12 and bone mineral den...
