Objective To explore the correlation analysis and predictive value of perimenopausal women's sex hormone level and osteoporosis. Methods Seventy cases of perimenopausal women with osteoporosis who came to our hospital from February 2023 to August 2024 were selected as the study group, and 70 cases of perimenopausal healthy women who came to our hospital for physical examination in the same time period were selected as the control group. Sex hormones [estradiol (E2), follicle stimulating hormone (FSH), luteinizing hormone (LH)], bone metabolism indexes [N-terminal pro-peptide of pre-collagen type I (PINP), N-terminal osteocalcin (N-MID), and β-collagen degradation products (β-CTX)], and bone mineral density (BMD) levels were compared between the two groups. The correlation between sex hormone levels and osteoporosis was analyzed. Working characteristic curves of the subjects were plotted to assess the predictive efficacy of sex hormone levels for osteoporosis. Results Compared with the control group, the study group had lower levels of serum E2, lumbar spine BMD, femoral neck BMD, and hip BMD, and higher levels of FSH, PINP, N-MID, and β-CTX. Serum E2 was negatively correlated with the levels of PINP, N-MID, and β-CTX (r=-0.341, -0.470, and -0.538, all P<0.001), and positively correlated with the levels of lumbar BMD, femoral neck BMD, and hip BMD (r=0.579, 0.527, and 0.522, all P<0.001). Serum FSH was positively correlated with the levels of PINP, N-MID, and β-CTX (r=0.361, 0.368, 0.522, all P<0.001), and negatively correlated with the levels of lumbar BMD, femoral neck BMD, and hip BMD (r=-0.536, -0.552, and -0.541, all P<0.001). The AUCs of serum E2, FSH and their combination for predicting osteoporosis in perimenopausal women were 0.890, 0.894, and 0.960, with 95% CIs of 0.826~0.936, 0.831~0.940, and 0.912~0.986, respectively, with sensitivities of 84.29%, 80.00%, and 91.43%, and specificities of 78.57%, 82.86%, and 92.86%, respectively. Conclusion Sexual E2 and FSH levels in perimenopausal women are closely related to the occurrence of osteoporosis, and the combination of the two is highly effective in predicting osteoporosis, which has good clinical application value.
