An update in bone mineral density status in Spain: the OsteoSER study.

Unlabelled: Bone mineral density (BMD) reference data for the Spanish population come from the Multicenter Research Project on Osteoporosis (MRPO) in 1989. The OsteoSER study updated Spanish BMD reference data, showing similarities with MRPO and NHANES III. Peak bone mass occurred at 20-39 years, positively associated with physical activity and negatively with smoking.

[Osteoporosis in young individuals].

Although there are some differential aspects related to peak bone mass acquisition and later bone loss throughout life between genders, the frequency of osteoporosis in young individuals is similar for both genders. In addition, in this population group, the development of osteoporosis is frequently associated with secondary causes. Indeed, nearly 50% of young individuals with osteoporosis have diseases or therapies related to the development of this disorder, with glucocorticoid therapy being one of the most frequently associated conditions.
