BONE DENSITY CHARACTERISTICS OF 10 TO 49 YEARS OLD IN THAI NGUYEN PROVINCE

Abstract

The objective of the study was to determine the bone mineral density of the lumbar spine, femoral neck, the entire head above the femur and whole body in healthy people in Thai Nguyen province aged 10-49 years by DEXA method. The cross-sectional descriptive study method was performed on 566 subjects living in Thai Nguyen province without bone or bone-related diseases. The results showed that bone mineral density (BMD) in the femoral neck increased gradually from 10 to 39 years old, and from 40 years old, it began to decrease gradually.. In the 10-19 age group, the BMD of the femoral neck and the entire supraclavicular head was similar between the sexes; but the BMD of the L1-4 vertebrae and the total body BMD of men are lower than that of women. From the age of 20-49 years, the majority of BMD in the positions of the femoral neck, the entire head above the femur, L1-L4 and the whole body in males was higher than those in females. Peak bone mass is reached at around 34 years of age in men and at around 30 years of age in women. The BMD of the femoral neck peaks at around 29 years of age in men and about 27 years of age in women. Skeletal muscle mass index is more closely related to bone density than fat mass index. The results of bone mineral density in the study should be used as a reference value for Thai Nguyen people.
