Special Issue Information

Dear Colleagues,

The relationship between physical and mental health is complex and inextricably linked. Uncovering the potential pathways that provide evidence for bidirectional causality and understanding the common risk factors that shape individual vulnerability and/or resilience could increase recognition of the importance of integrated care.

As healthcare providers, we have treated people with long-term physical conditions like diabetes, cardiovascular diseases, and/or chronic obstructive pulmonary disease who are frequently diagnosed with comorbid common mental disorders, like anxiety and depression. The need for constant symptom management and the lifestyle adjustments required can lead to psychological stress and reduced quality of life. On the other hand, mental health issues affect the ability to participate in healthy behaviors, resulting in problems with physical health and likely influencing treatment and recovery. This is more obvious in people with severe mental disorders who, partly due to physical ill health, have higher rates of morbidity and premature mortality compared with the general population.

Behavioral medicine implemented in consultation-liaison psychiatry combines knowledge and skills from biological, behavioral, psychological, and social sciences for the prevention, diagnosis, treatment, and rehabilitation of medical conditions through behavioral change and psychological factors management. Health psychology, via the biopsychosocial approach, focuses on how biological, psychological, and social factors influence health and disease, integrating knowledge from different disciplines to realize how people remain healthy, why they become ill, and how they respond, cope, and recover from the disease.

This Special Issue explores the diverse aspects of physical and mental health interactions, identifying how physical health conditions affect mental well-being and vice versa, and highlights the importance of an integrated approach to address these interactions for improved overall health outcomes.

The purpose of this Special Issue is to gather research articles, reviews, and/or meta-analyses on psychological problems in patients with physical health conditions and physical illness in patients with mental disorders, including other studies related to health psychology, behavioral medicine, and consultation-liaison psychiatry.

Background/Objectives: It is increasingly recognized that traumatic life experiences render individuals more vulnerable to gastrointestinal (GI) symptoms and chronic bowel conditions like inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). In this study, we examined whether this effect is mediated by negative affectivity. Methods: A total of 281 participants recruited in the Netherlands, including 94 with IBD, 95 with IBS and 92 controls, were assessed for lifetime trauma, trait anxiety, depression, and GI (IBD/IBS) disease activity. Results: The results confirmed that negative affectivity fully mediated the association between trauma and GI symptomatology, with trauma and depression explaining 38–40% (IBD|IBS) of the variance in disease activity and trauma and anxiety explaining 31–33% (IBD|IBS) of the variance in disease activity. Upon correction for condition (patient/controls), the predictive capacity increased even further, with trauma and depression now accounting for 43–44% (IBD|IBS) and trauma and anxiety for 40% (IBD and IBS) of the GI symptom heterogeneity. Conclusions: The results are in line with studies linking trauma to negative affectivity and negative affectivity to a more aggressive GI disease course. More generally, they show that the somatic and affective consequences of trauma should not be considered in isolation but must be treated as a covariant whole. Full article

Background: Immigration is a key factor contributing to population growth in Canada, a trend that is expected to continue. Immigrants generally arrive with better health than the Canadian-born population, but this advantage often diminishes over time, partially due to dietary acculturation. Emerging evidence points to a bidirectional link between nutrition and mental health. Objective: To explore the bidirectional relationship between nutrition and mental health and its impact on the health of Canadian immigrants, with a specific focus on immigrants’ mental health and the healthy immigrant effect. Methods: For this integrative review, two comprehensive literature searches were conducted in the databases MEDLINE, CINAHL, Embase, PsycINFO, Scopus, and Web of Science from inception to July 2024. The review adhered to Whittemore and Knafl’s integrative methodology, with the Mixed Methods Assessment Tool used to assess the quality of the studies. Results: A total of 42 and 34 scientific articles were included from the first and second literature searches, respectively. Four main themes emerged from the literature: (1) food insecurity and mental health, (2) obesity and mental health, (3) diet quality and mental health, and (4) the gut microbiome and mental health. These themes were explored in the context of Canadian immigrants’ health. Conclusions: The health of immigrants to Canada is likely shaped by complex, bidirectional interactions among various determinants of health, influencing both physical and mental well-being. As newcomers are expected to form an increasing proportion of the Canadian population, further research is needed to understand how the interaction between nutrition and mental health can help promote and safeguard the health of Canadian immigrants.
