Study on anxiety and depression of men who have sex with men: An application of group-based trajectory model

Causal associations between sexually transmitted infections, depression, and self-harm: a mendelian randomization and cross-sectional study

BACKGROUND

The causal relationships between sexually transmitted infections, depression, and self-harm remain unclear.

METHODS

We executed various Mendelian Randomization (MR) analyses. At the same time, a cross-sectional analysis from NHANES was used for verification and an enrichment analysis was also utilized to explore the potential common gene functions.

RESULTS

We found that STIs may have a potential causal effect on depression (P = 0.002) and self-harm (P = 0.003). Conversely, self-harm has been identified as a risk factor for the acquisition of STIs (P = 0.006), while there is no evidence to support an effect of depression on STIs. Furthermore, mediation MR indicated that monocyte absolute count played a mediating role in the association between STIs and depression, accounting for 7.7%. And then, the weighted regression analysis of the cross-sectional analysis demonstrated a significant association between one of the common STIs, HPV, and depression. Gene enrichment analysis suggested that the PI3K-Akt signalling pathway and the infectious virus signalling pathway may represent a common underlying pathogenesis.

CONCLUSION

STIs may increase the risk of depression and self-harm, while self-harm might also represent a risk factor for STIs, which could provide insights and a foundation for the control of STIs and mental health monitoring in clinical practice.

Brief Report: Depression, Substance Use, and Factors Associated With Sexual Risk Behaviors Among Adults Living With HIV in the Asia-Pacific Region

Background

Mental health and substance use disorders are common among people living with HIV and are associated with high-risk sexual behaviors, such as unprotected sex and multiple sexual partners, but Asia-Pacific data are limited.

Methods

Adult PLHIV in care at five Asia-Pacific HIV clinics were enrolled at routine clinic visits between July 2019 and June 2020. Depression, substance use, sexual practice and socio-demographic data were collected using PHQ-9, ASSIST, and a study-specific questionnaire. Clinical data were accessed from medical records. Risk factors for medium- to high-risk sexual practices, defined based on total scores from the sexual practice questionnaire assessing number of sexual partners and condom use, were analyzed using logistic regression. Moderate to severe depression was defined as a PHQ-9 score >9, and moderate- to high-risk substance use as an ASSIST score ≥11 for alcohol or ≥4 for other substances.

Results

Among 723 participants, median age was 38 years, 89% were male, 99% were on ART and 37% had medium- to high-risk sexual practices. Medium- to high-risk sexual practices were more common among those ≤30 years old, unemployed, and HIV status disclosed, and were more likely in participants with moderate to severe depression (aOR 2.09, 95%CI 1.17-3.74) compared to none to minimal depression, and moderate- to high-risk substance use (aOR 1.73, 95%CI 1.23-2.44) compared to those without.

Conclusions

Further integration of comprehensive sexual risk reduction strategies, mental health services and substance use harm reduction within HIV clinical settings in the region is needed.

Trajectories of anxiety and depression among Chinese men who have sex with men on pre-exposure prophylaxis: a group-based trajectory model approach

BACKGROUND

Anxiety and depression can influence adherence to Pre-exposure Prophylaxis (PrEP). However, there is limited research on the temporal dynamics of anxiety and depression among men who have sex with men (MSM) using PrEP.

METHODS

From December 2018 to November 2020, we administered the Hospital Anxiety and Depression Scale (HADS) to participants in the China Real-World Oral Intake of PrEP (CROPrEP) to measure their anxiety and depression levels. The group-based trajectory model (GBTM) depicted the dynamic changes of anxiety and depression scores over time.

RESULTS

A total of 1023 MSM were included, with 4523 follow-up assessments. The GBTM categorized the trajectories into three distinct patterns: consistently low (54.8% for anxiety, 60.7% for depression), consistently moderate (39.3% for anxiety, 31.4% for depression), and high but bell-shaped (5.9% for anxiety, 7.9% for depression). Higher anxiety levels were associated with being aged 18-30 years old, earning less than US$619 per month, female-identifying, adopting the bottom sexual role with men, and having two or more anal sex partners in the past three months; similarly, higher depression levels correlated with a monthly income under US$619, female-identifying, sexual behavior as bottom and a positive syphilis at baseline. PrEP adherence was notably lower in the high but bell-shaped anxiety and depression group compared to the other groups, particularly at the 12th-month follow-up.

CONCLUSIONS

Close monitoring of anxiety and depression levels in MSM on PrEP is crucial. Provision of targeted mental health support is essential to enhance PrEP effectiveness.
