Abstract

Recent studies have shown that circulating serotonin plays a potential role in bone metabolism. However, conflicting results have been reported for the relationship between serum serotonin concentrations and bone mineral density (BMD). We investigated whether the serum serotonin concentrations related to BMD in Chinese postmenopausal women. Serum serotonin and bone turnover concentrations of 117 premenopausal women and 262 asymptomatic postmenopausal women were analyzed by enzyme-linked immunosorbent assay. BMD at the lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry. The relationship between serotonin and BMD was investigated. The postmenopausal women had lower mean serum serotonin concentrations compared to the premenopausal women. Serotonin concentrations were negatively associated with age, weight, BMI, fat mass, and β-CTX concentrations in postmenopausal women. No significant correlations were found between serotonin and these parameters in premenopausal women. In postmenopausal women, age- and BMI-adjusted serotonin concentrations were positively correlated with BMD of the lumbar spine and femoral neck. Multiple regression analyses showed serum serotonin and β-CTX were the predictors for lumbar spine BMD. Only serum serotonin was the determinant for femoral neck BMD. In conclusion, lower serum serotonin concentrations are linked to low lumbar spine and femoral neck BMD in postmenopausal women.
