Controlling Nutritional Status score and postmenopausal osteoporosis.

Objective: This study investigated the association between CONUT score and postmenopausal osteoporosis.

Methods: Postmenopausal women who were seen at an outpatient clinic in a tertiary hospital for routine gynecologic examination between January 2017 and June 2022 were included in the study. Based on their T-scores, a total of 423 women were divided into two groups. Group 1 included 216 women with osteoporosis (T-score < -2.5 SD), and group 2 included 207 women with normal bone mineral density (T-score > -1 SD). The formula for the CONUT score corresponds to collection of scores from albumin, total cholesterol, and total lymphocyte count. Higher scores indicate poorer nutritional control.

Results: Mean age and mean age at menopause were similar in both groups. The duration of menopause, however, was higher in the women with osteoporosis (11.55 ± 6.82 vs 9.202 ± 6.14 y, P < 0.001). The 25-hydroxy vitamin D level was low in both groups. Body mass index of women with normal bone mineral density was higher than that of women with osteoporosis (31.54 ± 4.19 vs 28.52 ± 4.43 kg/m 2 , P < 0.001). The CONUT scores of the two groups were calculated and found to be higher in women with osteoporosis (3.180 ± 1.804 vs 0.391 ± 0.687, P < 0.001). According to the receiver operating characteristic curve analysis of the CONUT score for predicting osteoporosis, the area under the curve was calculated as 0.932, with a sensitivity of 86.6% and a specificity of 91.1% ( P < 0.001).

Conclusions: Diet plays an important role in the development of osteoporosis. In this study, it was shown that there is a relationship between CONUT score and osteoporosis.
