“…Obesity and osteoporosis have become common diseases in middle-aged and elderly people. Osteoporosis (OP) is a systemic bone disease characterized by decreased bone mass, destruction of bone microstructure, increased bone fragility, and is prone to fracture [1]. The complication of brittle fracture can seriously affect the quality of life of middle-aged and elderly people.…”

Objective: To understand the correlation between different degrees of obesity and bone mineral density (BMD). Methods: 772 cases (300 men and 472 females) of Zhuang over 40 years old were randomly selected. The BMD and T score were calculated by measuring the right heel bone using a quantitativeultrasound densitometer. Body composition index of body weight, waist circumference (WC), waist height ratio (WtHR), body fat percentage (BFP) and visceral fat (VF) were measured using a bioelectrical impedance method. Results: The BMI, WC, and WtHR of the male osteoporosis group were lower than those of the normal bone mass (NBM) group (P < 0.05). BMI, BFP, and WC in the female osteoporosis group were lower than those in the NBM group (P < 0.05); The BMI and WC in the osteoporosis group were lower than those of the NBM group (P < 0.05). After adjusting for factors such as age, weight, height, etc., the binary multivariate conditional logistic regression analysis showed that BMI was a protective factor for bone mass loss in men and women (P < 0.01). While the level of visceral fat was a risk factor for reduced bone mass (P < 0.05). Conclusion: BMI is positively correlated with BMD in Zhuang. BFP has a greater correlation with female BMD, and a small reduction in BFP can result in a significant decrease in BMD. BMD of male was positively correlated with abdominal obesity indicators (WC, WtHR, VF).
