失眠对绝经后女性骨密度的影响OA

Objective:This study aims to reveal the impact of insomnia on bone mineral density(BMD)in postmenopausal women.Methods:A retrospective case-control study was conducted among postmenopausal women who participated in questionnaire surveys and BMD tests from January 1,2017 to April 30,2024.Patients meeting the inclusion criteria were included.Statistical analysis was performed using SPSS 26.0.Results:There were no statistically significant differences in age,the age of menarche,the number of pregnancies,the number of children breastfed,the age at menopause,and the height between the insomnia group and the non-insomnia group.However,there were statistically significant differ-ences in weight and body mass index(BMI)(P<0.05).The T value of the lumbar spine in the insomnia group was significantly lower than that in the non-insomnia group(P<0.05),and the BMD of the lumbar spine was also lower.Bone mass loss occurred at a faster pace in the insomnia group than in the non-insomnia group(P<0.05),and the percentage of normal bone mass was lower in the insomnia group(P<0.05).The results of univariate and multivariate Logistic regression analysis showed that insomnia,age and the number of pregnancies were risk factors for bone loss(P<0.05),while BMI was a protective factor(P<0.05).Con-clusion:Insomnia may be a risk factor for BMD in postmenopausal women,and postmenopausal women with insomnia are at risk of low BMD in the lumbar spine.
