A moderated serial mediation analysis of the association between HIV stigma and sleep quality in people living with HIV: a cross-sectional study

Study on the Profiles of Sleep Disorders, Associated Factors, and Pathways Among Gynecological Cancer Patients - A Latent Profile Analysis

Background

Gynecological cancer generally refers to malignant tumors in gynecology, commonly including cervical cancer, endometrial cancer, and ovarian cancer. Patients with gynecological cancer often suffer from sleep disorders after clinical treatment. Except for serious sleep disorders, female characteristics, family roles, and feudal beliefs make their self-stigma at a medium to high level, leading to huge pressure. This study aims to identify potential categories of sleep disorders, and analyze the relationship between self-stigma, perceived stress, and sleep disorders.

Methods

A cross-sectional study was conducted in 2021-2022. Two hundred and two patients' data were collected from ShengJing Hospital Affiliated to China Medical University in Liaoning, Shenyang by using paper questionnaires for face-to-face surveys. The survey tools included the Pittsburgh Sleep Quality Index (PSQI), the Perceived Stress Scale (PSS), and the Social Impact Scale (SIS). Potential profile analysis (LPA), multiple logistic regression analysis, and structural equation modeling (SEM) were performed by Mplus 8.3, SPSS 26.0, and Amos 24.0 statistical tools, respectively.

Results

Three latent patterns of sleep disorders were found: "Good Sleep group (42.5%)", "Sleep Deficiency group (32.4%)", and "Sleep Disturbance group (25.1%)". Patients with high perceived stress were more likely to report a moderate (OR=1.142, 95% CI: 1.061-1.230) or high (OR=1.455, 95% CI: 1.291-1.640) level of sleep disorders. Self-stigma did not have a direct effect on sleep disorders (0.055, P>0.05), but it could have indirect effect on sleep disorders through perceived stress (0.172, P<0.01).

Conclusion

The perceptions of sleep disorders among gynecological cancer patients varies and exhibits individual differences. Gynecological cancer patients who feels alienated or discriminated may cause high pressure. This internal pressure can exacerbate sleep disorders.

Characteristics and influencing factors of anticipated HIV stigma among HIV-negative/unknown MSM in China: A regression mixture model

BACKGROUND

Anticipated HIV stigma among men who have sex with men's (MSM) has a severe negative effect on their physical and mental health wellbeing and hence requires specific attention. The current study aims to identify the characteristics and the psychosocial influencing factors of anticipated HIV stigma in MSM using regression mixture model (RMM) and to determine the cut-off point of the seven-item Anticipated HIV Stigma Questionnaire (AHSQ) using the receiver operating characteristic (ROC) analysis.

METHODS

A cross-sectional study was conducted among HIV-negative/unknown MSM from Blued online platform in China from December 16th, 2020 to March 1st, 2021, enrolling 1394 participants. Data were collected on demographic characteristics, perceived social support, anticipated HIV stigma, depressive symptoms, and HIV knowledge. Latent profile analysis was performed to identify different profiles of anticipated HIV stigma level. Chi-square test, analysis of variance, and RMM analysis were conducted to explore the influencing factors in different profiles. ROC analyses were carried out to identify the cut-off value of anticipated stigma.

RESULTS

Among the participants, three profiles of anticipated stigma were identified: "low anticipated HIV stigma" (12.0%), "moderate anticipated HIV stigma" (52.1%), and "severe anticipated HIV stigma" (35.9%). RMM analysis showed that higher income and higher levels of knowledge were positively associated with moderate anticipated HIV stigma, whereas full-time job and social support were negatively associated with moderate anticipated HIV stigma; higher income, depressive symptoms, and knowledge were positively associated with severe anticipated HIV stigma, whereas minor ethnicity and social support were negatively associated with severe anticipated HIV stigma. ROC curve of the AHSQ showed that the optimal cut-off value of ≥16 could indicate positive anticipated HIV stigma.

CONCLUSION

The study focuses on the level of anticipated HIV stigma and its psycho-socio influencing factors among HIV-negative/unknown MSM. It provides evidence for implementing relevant psychological interventions to HIV-negative/unknown MSM.

Psychological Mechanisms of Internalized HIV Stigma Affect Sleep Impairment among People Living with HIV in China: A follow-up Study

Prior studies have demonstrated that HIV-related stigma (e.g., internalized HIV stigma) is detrimental to the physical and mental health (e.g., sleep impairment and depressive symptoms) of people living with HIV (PLWH). However, follow-up data are limited regarding the longitudinal relationships between internalized HIV stigma, future orientation, self-esteem, depressive symptoms, and sleep impairment. The present study attempted to examine a mediation model involving these variables among Chinese PLWH. A two-wave follow-up design (6 months intervals) was employed in a final sample of 1,140 Chinese PLWH (Mage = 41.63, SD = 9.29, age range: 21-67 years; 64.6% men). Participants completed Internalized HIV Stigma Scale, Optimism About the Future Scale, Rosenberg Self-Esteem Scale, Center of Epidemiological Studies Depression Scale, and an adapted version of Pittsburgh Sleep Quality Index. Results revealed that internalized HIV stigma at baseline had a significant direct relationship with sleep impairment over time, and a significant indirect relationship with increased sleep impairment over time via future orientation and depressive symptoms. Furthermore, the linkage between internalized HIV stigma and sleep impairment was serially mediated via self-esteem and depressive symptoms. This study highlights the deleterious effects of internalized HIV stigma on the physical and psychological health of PLWH. The findings suggest that interventions targeting internalized HIV stigma and related factors such as future orientation, self-esteem, and depressive symptoms may facilitate improvements in sleep quality and overall well-being among PLWH.

The Moderating Role of HIV Stigma on the Relationship between Perceived Social Support and Antiretroviral Therapy Adherence Self-Efficacy among Adult PLHIV in South Africa

BACKGROUND

People living with human immune deficiency virus (PLHIV) grapple with distinct challenges, including HIV stigma which affects their antiretroviral therapy (ART) adherence self-efficacy. This study investigates the interaction of HIV stigma and perceived social support on ART adherence self-efficacy among adult PLHIV in South Africa.

METHODS

This study utilized a cross-sectional design that involved 201 participants selected using time location sampling at a tertiary health facility in Durban.

RESULTS

HIV stigma was significantly and negatively associated with self-efficacy (β = -7.860, t = -4.654, p = .001), with variations across different stigma levels (β = -5.844, t = -4.003, p = .001). Social support was significantly and positively associated with self-efficacy at lower HIV stigma levels (β = 7.440, t = 3.887, p = .001), in contrast to higher levels (β = -2.825, t = 1.400, p = .163).

CONCLUSION

Social support significantly influences ART adherence self-efficacy, particularly at lower levels of HIV stigma, but the effect of support weakens as stigma intensifies.
