Abstract

Introduction: Bone densitometry is used to diagnose OSTEOPENIA and OSTEOPOROSIS and, if necessary, prevent bone fractures, especially that of femoral neck. Dual X-ray absorptiometry (DXA) has become a common method to assay bone mineral density. Bone density is related to many factors such as race, age, sex, environmental factors, and nutrition. No comprehensive study has yet been performed in Iran.Methods: Among the 20-69 year-old population of Tehran, 553 (66% female, 34% male) persons from 50 clusters were randomly selected, following exclusion of people suffering from rheumatoid arthritis, thyroid disease, menstrual problem, fractures or other, conditions affecting bone metabolism. All participants underwent clinical examination and lumbar and spinal densitometry using DXA method.Results: In lumbar spine, the duration of peak bone density was between 20 and 29 years old and bone loss started at age of 40. In femoral neck, the duration of peak bone mass was from 20 to 29 years old in males and from 30 to 39 years old in females. Spinal bone loss in 60-69 year-old females and males were 19.6% and 7.9%, respectively; whereas those in femoral neck were 18.5% and 14.6%; respectively. The prevalence of spinal OSTEOPOROSIS in this age group was 32.4% in females and 9.4%in males.Conclusion: Mean bone densities of lumbar spine and femoral neck were higher in males than in females among all age groups. Peak bone densities in all the studied groups were lower than reported standard values, while the velocity of bone loss was compatible with standard values. It seems that the prevalence of OSTEOPENIA and OSTEOPOROSIS is higher in our study population. Peak bone density in 20-29 year-old population could be useful in policy-making for prevention and treatment of OSTEOPOROSIS.
