Background: Social determinants of health (SDoHs) are receiving growing attention and are particularly relevant to persons with schizophrenia-spectrum psychotic disorders (SSPDs), considering their heightened risk of comorbidities, cognitive and functional decline, and early mortality. Yet, we did not find any comprehensive review of multiple SDoHs in SSPD. Study Design: We conducted a scoping review of meta-analyses and systematic reviews of nine major SDoHs in SSPD. Study Results: Childhood abuse, parental psychopathology, parental communication problems, bullying, and urban settings with lower socioeconomic status were major risk factors for the greater incidence of SSPD and/or worse health. Social network size was inversely associated with overall psychopathology and negative symptoms. Experiences of racial/ethnic discrimination correlated with the prevalence of psychotic symptoms and experiences. Compared to native populations, the risk of psychosis was higher in immigrants, refugees, and asylees. Social fragmentation was associated with an increased prevalence of schizophrenia. Homeless populations had a 30-fold higher prevalence of schizophrenia than the general population. Seriously mentally ill people were 2.7 times more likely to report food insecurity than controls. The prevalence of non-affective psychosis in prisoners was 2.0%–6.5%, compared to 0.3% in the general population. Certain potentially positive factors like family and community resilience remain poorly studied. Conclusions: SDoHs are associated with higher rates of and worse outcomes in SSPD. Well-designed longitudinal studies are needed to understand SDoHs’ contribution to health in persons with SSPD, to develop interventions, and to implement changes in clinical care and public health policies that would reduce adverse health impacts of SDoHs. Positive SDoHs deserve greater attention.

As the numbers of older adults continue to increase globally, the need for facilitating healthy aging has become critical. While a physically healthy lifestyle, including exercise and diet, is important, recent research has highlighted a major impact of psychosocial determinants of health, such as resilience, wisdom, positive social connections, and mental well-being, on whole health. This article focuses on keeping the mind and brain healthy with psychosocially active aging. It has six sections: Philosophy Concepts of Wisdom, Resilience, and Well-Being; Wisdom: Clinical, Neurobiological, and Evolutionary Perspectives; Resilience, Adaptation, and Augmentation; Psychological Resilience, Brain Health, and Whole Person Health; Preventing Depression and Promoting Resilience and Well-Being in Old Age; and The Centenarian as a Model of Resilience and Well-Being. We discuss the biopsychosocial mechanisms and effectiveness of healthy lifestyle strategies and propose a framework for future research and its practical implications for promoting wisdom, resilience, and well-being at the individual, societal, and policy levels.

Social determinants of health have been shown to have a greater impact on overall health than traditionally considered medical risk factors, especially in people with mental disorders. It is the primary responsibility of healthcare providers to ensure that persons with psychiatric disorders are actively helped in reducing the adverse effects of SDoMH on their health and healthcare. Yet, the current clinical psychiatric practice in the U.S. does not have any standardized guidelines for evaluating or addressing these critical factors even among individuals who are receiving psychiatric and other medical treatment. Although there are several barriers to implementing such interventions, there are also practical approaches to address selected social determinants of mental health and improve the well-being of our patients. In this article, we review the literature on the assessment of relevant social factors and pragmatic psychosocial strategies at the individual, family, and community levels to help reduce their adverse impact. We offer guidelines for psychiatric clinicians and case managers to improve the health and quality of life of persons with mental disorders, using sustained inter-professional collaborative efforts.

Background: Social determinants of health (SDoHs) are nonmedical factors that significantly impact health and longevity. We found no published reviews on the biology of SDoHs in schizophrenia-spectrum psychotic disorders (SSPD). Study Design: We present an overview of pathophysiological mechanisms and neurobiological processes plausibly involved in the effects of major SDoHs on clinical outcomes in SSPD. Study Results: This review of the biology of SDoHs focuses on early-life adversities, poverty, social disconnection, discrimination including racism, migration, disadvantaged neighborhoods, and food insecurity. These factors interact with psychological and biological factors to increase the risk and worsen the course and prognosis of schizophrenia. Published studies on the topic are limited by cross-sectional design, variable clinical and biomarker assessments, heterogeneous methods, and a lack of control for confounding variables. Drawing on preclinical and clinical studies, we propose a biological framework to consider the likely pathogenesis. Putative systemic pathophysiological processes include epigenetics, allostatic load, accelerated aging with inflammation (inflammaging), and the microbiome. These processes affect neural structures, brain function, neurochemistry, and neuroplasticity, impacting the development of psychosis, quality of life, cognitive impairment, physical comorbidities, and premature mortality. Our model provides a framework for research that could lead to developing specific strategies for prevention and treatment of the risk factors and biological processes, thereby improving the quality of life and increasing the longevity of people with SSPD. Conclusions: Biology of SDoHs in SSPD is an exciting area of research that points to innovative multidisciplinary team science for improving the course and prognosis of these serious psychiatric disorders.

Cognitive impairment in various mental illnesses, particularly neuropsychiatric disorders, has adverse functional and clinical consequences. While genetic mutations and epigenetic dysregulations of several genes during embryonic and adult periods are linked to cognitive impairment in mental disorders, the composition and diversity of resident bacteria in the gastrointestinal tract—shaped by environmental factors—also influence the brain epigenome, affecting behavior and cognitive functions. Accordingly, many recent studies have provided evidence that human gut microbiota may offer a potential avenue for improving cognitive deficits. In this review, we provide an overview of the relationship between cognitive impairment, alterations in the gut microbiome, and epigenetic alterations during embryonic and adult periods. We examine how various factors beyond genetics—such as lifestyle, age, and maternal diet—impact the composition, diversity, and epigenetic functionality of the gut microbiome, consequently influencing cognitive performance. Additionally, we explore the potential of maternal gut microbiome signatures and epigenetic biomarkers for predicting cognitive impairment risk in older adults. This article also explores the potential roles of nutritional deficiencies in programming cognitive disorders during the perinatal period in offspring, as well as the promise of gut microbiome-targeted therapeutics with epigenetic effects to prevent or alleviate cognitive dysfunctions in infants, middle-aged adults, and older adults. Unsolved challenges of gut microbiome-targeted therapeutics in mitigating cognitive dysfunctions for translation into clinical practice are discussed, lastly.
