Abstract:

Objective To explore the correlation between anxiety disorder and insulin resistance(IR) in middle-aged and elderly. Methods A total of 159 patients aged 50 to 80 years who were first diagnosed with anxiety disorder were randomly selected as the study group from January 2019 to December 2019. 150 healthy subjects were randomly selected as the control group at the same time. Demographic data of two groups were collected, and the Hamilton Anxiety Scale(HAMA) was used for grading.Fasting insulin(FINS) and fasting blood glucose(FPG) were measured and compared between groups. Homeostatic model assessment of insulin resistance was used to calculate insulin resistance index(HOMA-IR).Pearson correlation analysis was used to explore relationship between anxiety disorder and IR in middle-aged and elderly.Results FINS, HOMA-IR, HAMA score were significantly higher in study group than in control group (all P<0.05). Pearson correlation analysis showed that HOMA-IR had no significant correlation with HAMA score(r=-0.049, P=0.536).Conclusion The level of IR in middle-aged and elderly with anxiety disorder is higher than in healthy people of the same age, but there is no correlation between IR and the severity of anxiety.
