Non-binary gender, vulnerable populations and mental health during the COVID-19 pandemic: Data from the COVID-19 MEntal health inTernational for the general population (COMET-G) study.

BACKGROUND: The COVID-19 pandemic has brought significant mental health challenges, particularly for vulnerable populations, including non-binary gender individuals. The COMET international study aimed to investigate specific risk factors for clinical depression or distress during the pandemic, also in these special populations. METHODS: Chi-square tests were used for initial screening to select only those variables which would show an initial significance. Risk Ratios (RR) were calculated, and a Multiple Backward Stepwise Linear Regression Analysis (MBSLRA) was followed with those variables given significant results at screening and with the presence of distress or depression or the lack of both of them. RESULTS: The most important risk factors for depression were female (RR = 1.59-5.49) and non-binary gender (RR = 1.56-7.41), unemployment (RR = 1.41-6.57), not working during lockdowns (RR = 1.43-5.79), bad general health (RR = 2.74-9.98), chronic somatic disorder (RR = 1.22-5.57), history of mental disorders (depression RR = 2.31-9.47; suicide attempt RR = 2.33-9.75; psychosis RR = 2.14-10.08; Bipolar disorder RR = 2.75-12.86), smoking status (RR = 1.15-5.31) and substance use (RR = 1.77-8.01). The risk factors for distress or depression that survived MBSLRA were younger age, being widowed, living alone, bad general health, being a carer, chronic somatic disorder, not working during lockdowns, being single, self-reported history of depression, bipolar disorder, self-harm, suicide attempts and of other mental disorders, smoking, alcohol, and substance use. CONCLUSIONS: Targeted preventive interventions are crucial to safeguard the mental health of vulnerable groups, emphasizing the importance of diverse samples in future research. LIMITATIONS: Online data collection may have resulted in the underrepresentation of certain population groups.

Causes of mortality in schizophrenia: An updated review of European studies.

BACKGROUND: The excess mortality in schizophrenia is still a phenomenon insufficiently studied on the cross-national level. It is important to analyse current studies on morality in schizophrenia since significant changes have recently taken place in psychiatric health care systems and guidelines of pharmacological treatment have been developed in European countries. SUBJECTS AND METHODS: This article reviews studies addressing mortality in schizophrenia in Europe that were published in English in the Pubmed database in 2009-2014. It aimed at determining countries where studies were conducted, methodologies and tools used, and current main mortality rates, as well as direction of causality in this group of patients. RESULTS: The recently published studies were conducted only in few European countries. The majority of data was obtained from general medical records and death records. The studies indicate that schizophrenia patients are characterized by higher mortality rate than the general population, with natural causes (cardiovascular diseases and cancers) and suicides predominating. The increasing mortality gap with significantly shorter life expectancy of patients with schizophrenia in comparison with the general population is considerable. CONCLUSIONS: Death records are a crucial tool in studies on mortality in schizophrenia patients; however they are insufficiently employed. Recent European reports do not show positive tendencies, indicating that standardized mortality rates in schizophrenia remain on the same level or even increase, particularly for deaths resulting from natural causes. Due to various methodologies used in studies, their direct comparison is difficult. This limitation warrants further discussion on methods used in future studies on schizophrenia mortality in Europe.
