BackgroundChronic insomnia disorder has become a significant public health issue， and it may be associated with dyslipidemia. Previous studies on dyslipidemia in patients with chronic insomnia disorder have mainly focused on exploring the relationship between subjective short sleep duration and dyslipidemia， while there have been limited studies on the relationship between objective short sleep duration and dyslipidemia. ObjectiveTo explore the relationship between objective short sleep duration and dyslipidemia in patients with chronic insomnia disorder， in order to provide references for the prevention and intervention of dyslipidemia in this population. MethodsA total of 103 patients who were hospitalized at The Third Hospital of Mianyang from August 2022 to November 2023 and met the diagnostic criteria for chronic insomnia disorder as defined in the International Classification of Sleep Disorder， third edition （ICSD-3） were retrospectively collected. The objective sleep duration of the patients was obtained through polysomnography. The patients were divided into two groups based on their objective sleep duration： the group with objective sleep duration ≥ 7 hours （n=71） and the group with objective sleep duration < 7 hours （n=32）. Binary Logistic regression analysis was used to explore the impact of objective sleep duration < 7 hours on dyslipidemia. ResultsAmong 103 patients with chronic insomnia disorder， 59 cases （57.28%） were identified with dyslipidemia. The comparison of dyslipidemia conditions between the group with objective sleep duration ≥ 7 hours and the group with objective sleep duration < 7 hours showed a statistically significant difference （χ²=5.956， P<0.05）. Compared with the group with objective sleep duration ≥7 hours， the group with objective sleep duration < 7 hours exhibited significantly lower high-density lipoprotein cholesterol levels， and reduced sleep efficiency （t=-2.003， -5.482， P<0.05 or 0.01）. Binary Logistic regression analysis results showed that the risk of abnormal blood lipids in patients with chronic insomnia disorder with objective sleep duration < 7 hours was 3.128 times higher than that of patients with objective sleep duration ≥ 7 hours （OR=3.128， 95% CI： 1.139–8.588）. ConclusionObjective short sleep duration may be a risk factor for dyslipidemia in patients with chronic insomnia disorder.

BackgroundInternet addiction poses serious harm to the physical and mental health of college students. Insecure attachment is one of the key factors of internet addiction， while self-compassion and psychological resilience serve as crucial psychological factors closely related to it. However， the chain mediating role of self-compassion and psychological resilience between insecure attachment and college students' internet addiction remains unclear. ObjectiveTo explore the mediating role of self-compassion and psychological resilience in the relationship between insecure attachment and internet addiction in college students， so as to provide references for the prevention and intervention of internet addiction in this population. MethodsFrom November 2023 to February 2024， a total of 1 380 college students were recruited using a cluster sampling method from two universities in Sichuan Province. The assessment was conducted using the Chinese Internet Addiction Scale （CIAS）， the Self-Compassion Scale （SCS）， the Experiences in Close Relationships Scale （ECR）， and the Resilience Scale for Chinese Adolescents （RSCA）. Pearson correlation analysis was conducted to examine the correlations of the scores of each scale. Model 6 in Process 4.2 was used to test the mediating roles of self-compassion and psychological resilience in the relationship between insecure attachment and internet addiction among college students. ResultsA total of 1 232 （89.28%） college students completed the valid questionnaire survey. The ECR score was positively correlated with the CIAS score （r=0.299， P<0.01）， and SCS score was positively correlated with the RSCA score （r=0.299， P<0.01）. The ECR score was negatively correlated with both SCS score and RSCA score （r=-0.122、-0.147，P<0.01）； the SCS score was negatively correlated with both RSCA score and CIAS score （r=-0.238、-0.263， P<0.01）. Self-compassion and psychological resilience were the pathways between insecure attachment and internet addiction， with effect sizes of 0.015 （95% CI： 0.007–0.023） and 0.010 （95% CI： 0.004–0.017）， respectively. Self-compassion and psychological resilience played chain mediating role between insecure attachment and internet addiction， with effect sizes of 0.003 （95% CI： 0.001–0.006）. ConclusionInsecure attachment can directly affect internet addiction in college students， and it can also influence internet addiction through independent pathway of self-compassion and psychological resilience， as well as the chain mediating pathways involving both self-compassion and psychological resilience.
