Objective: To study the relation between adult vertebral bone mineral density (BMD) and gender and age in Foshan, to explore the average BMD of each age group and osteoporosis (OP) incidence distribution in the region. Methods: Quantitative computed tomography (QCT) was used to examine and record the vertebral BMD of 1065 (male 648, female 417) healthy adults who underwent physical examination in Foshan Hospital of TCM from October 2021 to March 2023, and grouped according to age, T test and variance analysis were used on BMD in different sex and age group. Chi square analysis and correlation analysis were used on the incidence of OP in different sex and age group. Results: There was significant difference in the BMD between male and female of 20~29, 30~39, 40~49 and 60~69, 70~79 years old, women had higher peak BMD than man in young to middle age. In the male groups of 40~49、50~59, 60~69, 70~79 and female groups of 30~39, 40~49, 50~59, 60~69 years old, there were also significant differences in BMD in different age groups of the same sex, and decreased with age. There was significant difference in the incidence of OP between different age groups in the male and female groups. Age was positively related to the incidence of OP (r=0.517 for male and r=0.636 for female). Conclusion: The vertebral BMD derived from QCT for healthy adults in Foshan are associated with sex and age, peaked at 20~29 years old, and decreased with age. The incidence of OP for male and female increased with age from 40~49 years old.
