There is a substantial body of literature on environmental risk associated with schizophrenia. Most research has largely been conducted in Europe and North America, with little representation of the rest of the world; hence generalisability of findings is questionable. For this reason, we performed a mapping review of studies on environmental risk for schizophrenia spectrum disorders, recording the country where they were conducted, and we linked our findings with publicly available data to identify correlates with the uneven global distribution. Our aim was to evaluate how universal is the ‘common knowledge’ of environmental risk for psychosis collating the availability of evidence across different countries and to generate suggestions for future research identifying gaps in evidence.

We performed a systematic search and mapping of studies in the PubMed and PsycINFO electronic databases reporting on exposure to environmental risk for schizophrenia including obstetric complications, paternal age, migration, urbanicity, childhood trauma, and cannabis use and subsequent onset of schizophrenia spectrum disorders. This search focused on articles published from the date of the first available publication until 31 May 2023. We recorded the country where they were conducted. We downloaded publicly available data on population size, measures of wealth, medical provisions, research investment, and of quality research outputs per country and performed regression analyses of each predictor with the number of studies and recruited cases in each country.

We identified 308 publications that included a sample size of 445,000 patients with schizophrenia spectrum disorders. The majority were conducted in northern Europe and North America, with large parts of the world totally unrepresented. In the associations between the number of environmental risk studies for schizophrenia with potential predictors, we found that neither population nor wealth or research investment were strong predictors of research outputs in the field. Interestingly, the stronger correlations were found for number of researchers per population and for indicators of top-end scientific achievements, such as number of Nobel laureates per country.

Our results demonstrate a gap of knowledge due to the underrepresentation of studies on environmental risk of schizophrenia spectrum disorders in large parts of the world. This has implications not only in the generalisability of any findings from research conducted in the Northern hemisphere but also in our ability to progress in efforts to make causal inferences about biological pathways to schizophrenia. These findings reinforce the need to focus research on populations that are underrepresented in research and underserved in health care.

About one-third of South African women have clinically significant symptoms of postpartum depression (PPD). Several socio-demographic risk factors for PPD exist, but data on medical and obstetric risk factors remain scarce for low- and middle-income countries and particularly in sub-Saharan Africa. We aimed to estimate the proportion of women with PPD and investigate socio-demographic, medical and obstetric risk factors for PPD among women receiving private medical care in South Africa (SA).

In this longitudinal cohort study, we analysed reimbursement claims from beneficiaries of an SA medical insurance scheme who delivered a child between 2011 and 2020. PPD was defined as a new International Classification of Diseases, 10th Revision diagnosis of depression within 365 days postpartum. We estimated the frequency of women with a diagnosis of PPD. We explored several medical and obstetric risk factors for PPD, including pre-existing conditions, such as HIV and polycystic ovary syndrome, and conditions diagnosed during pregnancy and labour, such as gestational diabetes, pre-term delivery and postpartum haemorrhage. Using a multivariable modified Poisson model, we estimated adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) for factors associated with PPD.

Of the 47,697 participants, 2,380 (5.0%) were diagnosed with PPD. The cumulative incidence of PPD increased from 0.8% (95% CI 0.7–0.9) at 6 weeks to 5.5% (5.3–5.7) at 12 months postpartum. PPD risk was higher in individuals with history of depression (aRR 3.47, 95% CI [3.14–3.85]), preterm delivery (1.47 [1.30–1.66]), PCOS (1.37 [1.09–1.72]), hyperemesis gravidarum (1.32 [1.11–1.57]), gestational hypertension (1.30 [1.03–1.66]) and postpartum haemorrhage (1.29 [0.91–1.85]). Endometriosis, HIV, gestational diabetes, foetal stress, perineal laceration, elective or emergency C-section and preeclampsia were not associated with a higher risk of PPD.

The PPD diagnosis rate was lower than anticipated, based on the PPD prevalence of previous studies, indicating a potential diagnostic gap in SA’s private sector. Identified risk factors could inform targeted PPD screening strategies.

Antenatal depression symptom is a global health concern, but the trajectories of antenatal depression symptom vary across different studies. Additionally, the influencing factors and adverse pregnancy outcomes of antenatal depression symptom may differ across heterogeneous subtypes, which requires further exploration.

A prospective cohort study was conducted in Hubei province, China, from July 2022 to September 2023. Pregnant women (<14 weeks) were enrolled and followed up at 16, 21, 28, and 37 gestational weeks, with depressive symptom measured using the Edinburgh Postnatal Depression Scale (EPDS). Latent class growth modeling and logistic regression were used for data analysis.

Of 1034 women enrolled, 725 completed all follow-ups. Four depressive symptom trajectories were identified: no depression group (32.13%), persistent subclinical depression group (42.48%), persistent moderate depression group (19.17%), and persistent high depression group (6.21%). Risk factors of depressive symptom trajectories included low social capital, unplanned pregnancy, primiparity, mental illness history, high perceived stress, and low resilience (p < 0.05). Compared to the no depression group, gestational diabetes mellitus (GDM) risk was 1.90 times higher in the persistent moderate group and 2.59 times higher in the persistent high group; small for gestational age (SGA) risk was 2.42 times higher in the persistent moderate group and 3.98 times higher in the persistent high group.

This study identified four antenatal depressive symptom trajectories. Persistent moderate and high depression groups were linked to GDM and SGA, highlighting the importance of mental health assessments and intervention for pregnant women, especially those with higher depression severity, to prevent adverse outcomes.

This study investigated the factors influencing the mental health of rural doctors in Hebei Province, to provide a basis for improving the mental health of rural doctors and enhancing the level of primary health care.

The aim of this study was to understand the mental health of rural doctors in Hebei Province, identify the factors that influence it, and propose ways to improve their psychological status and the level of medical service of rural doctors.

Rural doctors from 11 cities in Hebei Province were randomly selected, and their basic characteristics and mental health status were surveyed via a structured questionnaire and the Symptom Checklist-90 (SCL-90). The differences between the SCL-90 scores of rural doctors in Hebei Province and the Chinese population norm, as well as the proportion of doctors with mental health problems, were compared. Logistic regression was used to analyse the factors that affect the mental health of rural doctors.

A total of 2593 valid questionnaires were received. The results of the study revealed several findings: the younger the rural doctors, the greater the incidence of mental health problems (OR = 0.792); female rural doctors were more likely to experience mental health issues than their male counterparts (OR = 0.789); rural doctors with disabilities and chronic diseases faced a significantly greater risk of mental health problems compared to healthy rural doctors (OR = 2.268); rural doctors with longer working hours have a greater incidence of mental health problems; and rural doctors with higher education backgrounds have a higher prevalence of somatization (OR = 1.203).

Rural doctors who are younger, male, have been in medical service longer, have a chronic illness or disability, and have a high degree of education are at greater risk of developing mental health problems. Attention should be given to the mental health of the rural doctor population to improve primary health care services.

The COVID-19 pandemic and associated restrictive measures affected the mental health and well-being of individuals globally. We assessed non-modifiable and modifiable factors associated with the change in well-being and mental health from before to during the COVID-19 pandemic in South Africa.

A cross-sectional online survey was conducted from 26 April, 2020, to 22 April, 2021. Paired samples t-tests were conducted to assess change in well-being (measured on The World Health Organization-Five Well-Being Index (WHO-5)) and mental health (a validated composite psychopathology p-score). Sociodemographic, environmental, clinical, and behavioural factors associated with change in outcomes were examined.

The sample comprised of 1866 adults (M age = 44.26 ± 17.36 years, female = 78.9%). Results indicated a significant decrease in well-being (p < 0.001) and increase in p-score (p < 0.001) from before to during the pandemic. Having a prior mental health condition was associated with a worsening well-being score, while being female was associated with a worsening p-score. Being of Black African descent was associated with improved p-score and higher socio-economic status (SES) was associated with improved well-being. Factors associated with worsening of both well-being and the p-score included adulthood adversity, financial loss since COVID-19, and placing greater importance on direct contact/interactions and substance use as coping strategies. Higher education level and endorsing studying/learning something new as a very important coping strategy were associated with improved well-being and p-score.

Findings inform the need for targeted interventions to reduce and prevent adverse well-being and mental health outcomes during a pandemic, especially among vulnerable groups.

This study presents the most recent data on the incidence, prevalence, and years lived with disability (YLDs) due to anxiety disorders across the Middle East and North Africa (MENA) region from 1990–2021, analysed by sex, age, and sociodemographic index (SDI).

We reported the burden of anxiety disorders using data sourced from the Global Burden of Disease 2021 study. The estimates of prevalence, DALYs, and YLDs are provided as numbers and age-standardised rates, accompanied by their 95% uncertainty intervals (UIs).

In 2021, the age-standardised point prevalence of anxiety disorders in the region was 5.95 thousand, with an incidence rate of 883.4 per 100,000. The number of YLDs in 2021 reached 4.5 million. From 1990 to 2021, the burden of anxiety disorders increased significantly. Lebanon had the highest burden in 2021. Among both sexes, the 10–14 age group had the highest incidence rate, while the 15–19 age group had the highest prevalence and YLD rates. In 2021, most age groups in the MENA region had YLD rates that were higher than the global average.

This study highlights the urgent need for a multidisciplinary approach to prevent and manage anxiety disorders. Ensuring accessible and affordable treatment options for all affected individuals is crucial. Governments should prioritise supporting programmes to effectively address mental health issues, given the unique socioeconomic and geopolitical challenges in the MENA region. By including effective preventive methods alongside treatment in healthcare strategies, the burden of anxiety disorders can be significantly reduced.

The focus of suicide research changes from traditional risk factors to acute warning signs. Patient self-reported suicidal ideation (SI) is not a reliable measure of acute suicide risk. Presuicidal syndromes such as suicide crisis syndrome (SCS) attempt to describe measurable syndromes based on warning signs other than SI.

Seven hundred and ten acutely admitted patients were included in the study. Identification of symptoms describing the five components of SCS was done by performing a retrospective text analysis of the patient records (electronic medical records). Patients were grouped according to high or low level of SCS symptoms. We performed statistical tests for group differences in demographics, traditional risk factors, and clinical variables, including agitation assessed by the Positive and Negative Symptom Scale-Excited Component (PANSS-EC).

Seventy-two patients had high levels of SCS symptoms. They reported less SI the last month before admission; suicidality was less relevant for referral, the intake suicide assessment more often concluded with high suicide risk, they were more often referred and admitted involuntarily, and they had higher total scores on PANSS-EC.

The individual SCS symptoms may provide useful information in the evaluation of acute suicide risk at intake. A high level of SCS symptoms suggests more severe conditions. The lower reports among high-level than low-level SCS patients of self-reported SI last month before admission, shows the limitation of using SI as a warning sign. The association between the level of SCS symptoms and PANSS-EC total score suggests that agitation could give valuable additional information for suicide risk assessments.

Older adults are more likely to develop delirium with COVID-19 infection. This cross-sectional cohort study was designed to explore the risk factors of delirium in hospitalized older adults with COVID-19 and to evaluate whether delirium is an independent predictor of mortality in this cohort of patients.

Data were collected through a retrospective clinical chart review of patients aged 65 years or older who were admitted to St. James’s Hospital between March 2020 and 2021 who tested positive for SARS-CoV-2 infection.

A total of 261 patients (2.8 % of total admissions 65 years or older) were included in this study. Patients who developed delirium were older (80.8 v. 75.8 years, p < 0.001), more likely to have pre-existing cognitive impairment (OR = 3.97 [95% CI 2.11–7.46], p < 0.001), and were more likely to be nursing home residents (OR = 12.32 [95% CI 2.54–59.62], p = 0.0018). Patients who developed delirium had a higher Clinical Frailty score (mean 5.31 v. 3.67, p < 0.001) and higher Charlson Co-morbidity index (mean 2.38 v. 1.82, p = .046). There was no significant association between in-hospital mortality and delirium in the patient cohort (p = 0.13). Delirium was associated with longer hospital stay (40.5 days v. 21 days, P = 0.001) and patients with delirium were more likely to be discharged to nursing homes or convalescence instead of home (OR = 8.46 [95% CI 3.60–19.88], p < 0.001).

Delirium is more likely to occur in COVID-19 patients with pre-existing risk factors for delirium, resulting in prolonged admission and functional decline requiring increased support for discharge.
