Obstructive Sleep Apnea in Psychiatric Inpatients

Assessing the causal relationship between psychiatric disorders and obstructive sleep apnea: a bidirectional Mendelian randomization

Background

Extensive observational evidence suggests an association between psychiatric disorders (PDs) and obstructive sleep apnea (OSA), but their causal relationship remains unexplored. The objective of this study was to examine the causal relationship between PDs and OSA.

Methods

Mendelian randomization (MR) analysis was conducted with summary genetic data from the FinnGen and Psychiatric Genomics Consortium (PGC). Inverse-variance weighted (IVW), MR-Egger, weighted median, and weighted mode methods were employed to ascertain causal influence. Sensitivity analysis employing various methodologies assessed the robustness of the findings. Furthermore, multivariable Mendelian randomization (MVMR) was used to clarify if the exposures independently caused OSA.

Results

MR analysis showed that genetically determined major depressive disorder (MDD) increased the risk of OSA (IVW odds ratio [OR]: 1.377, 95% confidence interval [CI]: 1.242-1.526, P = 1.05×10-9). Sensitivity analysis showed no evidence of pleiotropy and heterogeneity. In MVMR, the significant association persisted after adjusting for BMI, smoking, and alcohol consumption. No conclusive evidence indicated the causal impact of other psychological characteristics on OSA. In the reverse MR analyses, there was no causal effect of OSA on PDs.

Conclusion

This study suggests a causal effect of MDD on OSA risk. Further research is needed to confirm these findings and understand how MDD contributes to OSA development, potentially aiding in reducing OSA incidence.

Predictors of common mental disorders and psychiatric medication use among faculty members

PURPOSE

Identify the predictors of common mental disorders (CMD) and psychiatric medication use by faculty members in different teaching units of a public university.

DESIGN AND METHODS

A cross-sectional study on 253 faculty.

FINDINGS

Being single, not having children, and not practicing physical activity were identified as predictors of CMD. Relative to psychiatric medication use, the predictors were the following: being homosexual, teaching classes in the biological sciences field, using medication for the urinary tract and sexual hormones, presenting mental disorder/sleep disorder diagnoses, and being positive for CMD.

PRACTICE IMPLICATIONS

The findings of this study may subsidize more effective interventions aimed toward protecting the health and preventing aggravation in these professionals, as well as measures for promoting changes in the university work context.
