Age is one of the most important factors that influence bone condition. At the age of 4045 years for women (F) and 50 years for men (M) processes of bone formation and resorption are balanced, then bone resorption predominates.
We examined 103 M (2078 years) and 360 F (2087 years), residing in the Republic of Karelia. Densitometry was performed for all patients to assess age-related changes in bone mineral density (BMD) at the lumbar spine. At F from 20 to 40 years and M up to 50 years, averages of vertebral BMD had no significant differences. A significant decrease in BMD was observed after 40 years. At F reduction in BMD for every 5 years were: aged 4050 years 1.7% (0.3% per year), 5060 3.8% (0.8% per year), after 60 only 1.72.5% (0.30.5% per year), for 75 20% (0.7% per year), to 8187 25.2%. At M BMD reduction were: aged 4560 years 2.7% (0.5% per year), after 60 1.5% (0.3% per year), to 7178 11.1%. Statistically significant (P<0.05) decrease in BMD in F detected in 4145 years, and in M in 5155 years. 89% of F under the age of 50 years had normal BMD, and aged 5160 years 44.4%. Osteoporosis (OP) was detected in 55.6% F aged 5060 years, and in aged 7180 years 42.3%, in aged 81 years and older in 57.1%. In males under 40 years, 70% of the BMD values were normal, at 6170 years in 44.7% of M was revealed osteopenia and OP was observed in 23% of M over 70 years.
Thus, a statistically significant decrease in BMD in female found in the age period of 4145 years, in male in 5155 years. OP was detected in women after age 50, men after 70 years.
