Purpose of review: To provide a summary of the most up-to-date thoughts about treatment for schizophrenia at different stages of illness.

Recent findings: The use of Coordinated Specialty Care clinics has arisen as the standard for early on in the treatment of psychosis, providing the notion that recovery is possible. New medications that do not depend on postsynaptic dopamine receptor blockade are soon becoming available.

Summary: A focus should be made by clinicians to personalize treatment plans for each patient who has the possibility of being diagnosed with a primary psychosis and the plan should be to predict outcomes based on biological markers that include genetic vulnerability, early psychosocial combined with pharmacological treatments as needed and then a plan to determine or maintain treatments going forward into the future. It is important to individualize treatment by stage of illness, as well as characteristics of the individual patient. Research is ongoing to advance knowledge for interventions at each stage from the premorbid period through to chronicity.

Purpose of review: To offer an integrative overview of mental health services in urban areas across different social groups and underscore the challenges and potential solutions to improve access to mental health services in urban areas.

Recent findings: The process of urbanization places a lot of toll on the current mental health services system. Challenges to both mental health and mental health services include the elevated risk of some mental and behavioral health issues, the increased demand for mental health services, and the intensification of mental health inequalities. The phenomenon of mental health inequalities is exacerbated in urban areas, with certain disadvantaged population groups more likely to report higher mental health issues and difficulties in accessing mental health services. Targeted and dedicated strategies are warranted to develop and allocate resources to address the mental health services needs among those simultaneously with multiple disadvantaged social and economic characteristics.

Summary: Urbanization places a substantive burden on both mental health and mental health services and creates challenges to mental health services access. Integrative and multisectoral initiatives could shed light on effectively addressing the issues of access to mental health services in urban cities.

Purpose of review: Urbanization, a complex global phenomenon, has a significant bearing on schizophrenia/psychosis burden through various socioeconomic and environmental factors. This review focuses on recent evidence (2019-2023) linking urbanization, schizophrenia, and the role of green space.

Recent findings: This review analyzed 43 articles that examined the correlation between urban birth or upbringing, urban living (urbanicity), and various schizophrenia/psychosis-related outcomes such as incidence, psychotic experiences, etc. The studies showed differing results across geographical locations. Socioeconomic factors like area deprivation, migrant status (ethnic density) and social fragmentation were independently associated with the risk of schizophrenia/psychosis irrespective of urbanicity. More recently, environmental factors such as green space reduction and air pollution have been explored in urban living conditions and were positively associated with an increased risk of schizophrenia/psychosis.

Summary: There is a need for further investigation in low and middle-income countries. The impact of urbanization-related factors and green space on the risk of schizophrenia/psychosis calls for appropriate governmental commitments toward structured and healthy urban planning.

Purpose of review: The assumption has been made that urbanization adversely affects mental health, primarily attributed to the lack of access to nature. Our objective is to examine whether nature-based interventions can reduce psychopathology within an urban setting.

Recent findings: Nature-based interventions are generally categorized as either physical or virtual. Physical interventions engage participants in various activities like passive exposure, outdoor swimming, or physical activities in natural environments. On the other hand, virtual interventions expose participants to visual, auditory, or even olfactory stimuli to simulate natural environments. While most interventions achieved some degree of success in enhancing overall well being, not all demonstrated a significant reduction in depression and anxiety.

Summary: The review identified a shortage of well designed and well implemented outdoor or virtual nature-based interventions. Longitudinal designs in physical nature-based interventions provided the strongest evidence for reducing anxiety and depression. Multisensory virtual nature-based interventions also show significant potential for alleviating anxiety and depression in urban dwellers. Conversely, brief nature-based interventions yielded inconsistent results in improving mental health. Urgent investment in high-quality interventions and research in this domain is imperative to inform policy and enhance overall mental health in urban settings.

Purpose of review: Urbanization is a multifaceted process that can have both positive and negative effects on mental health, especially in adolescents. This paper attempts to summarize the impact of urbanization on youth mental health in Hong Kong.

Recent findings: Several studies have shown that urbanization is associated with an increased risk of youth mental health problems in Hong Kong. Psychosocial factors like perceived stress, social isolation, and exposure to environmental pollutants may contribute to a negative association between urbanization and mental health issues. Academic pressure, poor transparency and accessibility to mental health services in Hong Kong further exacerbate youth's mental health wellbeing. Environmental factors like housing conditions, green spaces, and visible urban greenery have been found to influence mental health outcomes. Existing empirical studies have found a positive association between urbanization and mental health problems, while others have found no association or even a negative association.

Summary: Further research is warranted to investigate the complex relationship between urbanization and youth mental health in Hong Kong. Exploration of effective interventions is necessary to mitigate the negative impacts of urbanization on youth mental health. Understanding this relationship can inform health policy-making and formulate interventions to promote youth's mental health well being in the short-and long run.

Purpose of review: Social withdrawal syndrome, known as "hikikomori," has been highlighted since the late 1990 s in Japan. Hikikomori is more common in urban areas, and often comorbid with mental disorders, and now spreading throughout the world. In the post-COVID-19 era, not outing is no longer considered pathological in itself as the "new normal," and a novel concept of hikikomori is needed. This review summarizes the concept of hikikomori, and presents the latest methods for identification of hikikomori.

Recent findings: The novel definition can distinguish between pathological and non-pathological hikikomori using the scale of "Hikikomori Diagnostic Evaluation (HiDE)," which has been developed in the hikikomori research lab at Kyushu University. An online survey among non-working adults has revealed that persons who have become pathological hikikomori for less than three months showed a particularly strong tendency toward gaming disorder and depression.

Summary: Now, physical isolation itself is not pathological, but when dysfunction and distress are present, rapid mental health support should be provided. In the novel urban society, the establishment of a checkup system to assess whether persons who stay home are happy or suffering is important for prevention against mental disorders triggered by social isolation.

Purpose of review: About one in four children in China is a migrant child. This population has a higher risk of experiencing loneliness. However, existing studies present conflicting findings regarding the levels of loneliness among migrant children as compared to local urban children in urban China. This review performs a meta-analysis of studies comparing loneliness levels between these two groups.

Recent findings: A literature search of major Chinese- and English-language databases revealed 27 eligible comparative studies. These studies reported the means and standardized deviations of loneliness scores for both migrant and nonmigrant children in urban China. Meta-analysis results showed that migrant children experienced significantly higher levels of loneliness than their urban nonmigrant counterparts [standardized mean difference (SMD) = 0.21, P  < 0.001]. Subgroup analysis revealed that studies enrolling migrant children from migrant children's schools had significantly higher pooled SMDs than those enrolling children from public schools (0.346 vs. 0.120, P  = 0.047).

Summary: Migrant children in urban China experience higher levels of loneliness compared to their local urban peers. Efforts to create a socially inclusive, migrant-friendly environment and reduce social isolation among migrant children are crucial to help alleviate their feelings of loneliness.

Purpose of review: Controversy remains about the difference in mental health status among children and adolescents between one-child and multichild families in China. Thus, we conducted a meta-analysis of studies comparing mental health status between both groups and explored their potential moderating factors.

Recent findings: Totally, 113 eligible studies encompassing 237 899 participants (one-child families: 83 125; multichild families: 154 774) were included. The pooled SMD of SCL-90 total score was -0.115 [95% confidence interval (95% CI): -0.152; -0.078; I2  = 86.9%]. Specifically, children and adolescents from one-child families exhibited lower scores in terms of somatization (SMD = -0.056; 95% CI: -0.087; -0.026), obsessive-compulsive symptoms (SMD = -0.116; 95% CI: -0.154; -0.079), interpersonal sensitivity (SMD = -0.140; 95% CI: -0.171; -0.109), depression (SMD = -0.123; 95% CI: -0.159; -0.088); anxiety (SMD = -0.121; 95% CI: -0.151; -0.092); phobic anxiety (SMD = -0.124; 95% CI: -0.166; -0.081); paranoid ideation (SMD = -0.040; 95% CI: -0.070; -0.009); and psychoticism (SMD = -0.119; 95% CI: -0.148; -0.089). Study publication year was significantly associated with differences in mental health status between both groups ( P  = 0.015).

Summary: Children and adolescents from one-child families had better mental health status compared to those from multichild families in China. Future studies should investigate the underlying factors contributing to such mental health differences, and the potential interventions that could address these mental health problems.

Purpose of review: Economic development and urbanisation have prompted many Chinese parents to move from rural to urban regions for better job opportunities. Their children, who remain behind in rural regions, become left-behind children (LBC). With absent parents, children and adolescents are unable to maintain the secure attachment required for healthy social and emotional development, increasing the risk of mental illness. This study aimed to compare risk of self-harm and suicidal ideation in LBC and non-LBC in China.

Recent findings: Greater risks for poor mental health outcomes including worse depression, loneliness and anxiety have been identified in LBC in cross-sectional studies. Previous studies have also identified higher prevalence of bullying victimization, poorer school performance and worse school attendance amongst LBC.

Summary: Findings indicate that prolonged separation from parents put LBC at greater risks of poor mental health. Policy changes to allow children to migrate with their parents and policies to reduce inequalities in job opportunities between urban and rural regions are needed.
