| Objective Quantitative CT (QCT) was used to measure the bone mineral density (BMD) of the lumbar vertebrae to explore the correlation between blood pressure level and BMD of lumbar vertebrae in male hypertension patients. Methods A total of 361 male patients aged 21-80 years who were hospitalized in Qingdao Municipal Hospital from December 2020 to January 2022 were selected. Their general information was collected and they were divided into normal blood pressure group, hypertension grade 1 group, hypertension grade 2 group and hypertension grade 3 group according to their blood pressure. The abdominal CT scan was performed, and quantitative CT was used to obtain lumbar bone density. According to the measurement value of lumbar BMD, the patients were divided into normal bone mass group, low bone mass group and osteoporosis group. Results There were no significant differences in BMI, TC, HDL-C and LDL-C between different BMD groups in different age groups (P > 0.05). In 51~65 years group and 66~80 years group, the BMD of lumbar vertebra decreased with the increase of TG (P < 0.05). Only in the age group of 51 to 65 years, lumbar BMD of different blood pressure grades was significantly different (P < 0.05), and the course of hypertension, SBP, DBP and PP were negatively correlated with lumbar BMD (P < 0.05). The higher the blood pressure grade was, the higher the incidence of low bone mass and osteoporosis was. Multiple linear stepwise regression analysis showed that age, SBP, TG and BMI could into the equation finally. Conclusions There is a certain correlation between hypertension and BMD in males aged from 50 to 65 years. Age, SBP and TG were independent risk factors for decreased lumbar bone mineral density, while BMI was a protective factor for decreased lumbar bone mineral density. |
