The reciprocal associations between social deficits, social engagement, and inflammation: Longitudinal evidence comparing venous blood samples and dried blood spots and mapping the modifying role of phenotypic and genotypic depression.

BACKGROUND: Social psychoneuroimmunology suggests an interplay between social deficits (loneliness and isolation) and chronic inflammation, but the direction of these relationships remains unclear. We estimated the reciprocal associations of social deficits and social engagement with levels of C-reactive protein (CRP), compared the consistency of the findings depending on the biological sampling method used, and examined the modifying role of phenotypic and genotypic depression. METHODS: We used longitudinal nationally representative data from the US (Health and Retirement Study, 3 waves, 2006-16) and England (English Longitudinal Study of Ageing, 4 waves, 2004-18). Loneliness, social isolation, and social engagement were self-reported. CRP was measured using dried blood spots (US) and venous blood samples (England). Cross-lagged panel models were fitted and tested interactions with phenotypic depression (above-threshold depressive symptom scores) and genotypic depression (polygenic score for major depressive disorder). RESULTS: We included 15,066 participants (mean age = 66.1 years, SD = 9.8) in the US and 10,290 (66.9 years, SD = 10.5) in England. We found reciprocal associations between loneliness and CRP using dried blood spots and venous blood samples. Higher CRP predicted higher subsequent loneliness and higher loneliness predicted elevated CRP. Both phenotypic and genotypic depression modified this reciprocal association. There were also reciprocal associations for social engagement in venous blood samples: higher CRP predicted lower social engagement and greater social engagement predicted lower subsequent CRP. Associations between social isolation and CRP were inconsistent and unidirectional. CONCLUSIONS: Loneliness may increase chronic inflammation, whereas social engagement may reduce inflammation. As these relationships were reciprocal, there may be a loop between inflammation, loneliness, and social engagement. This loop was stronger in those with depression or at high genetic risk for major depressive disorder. This relationship for loneliness was present in both blood sampling methods despite contrasting methods of CRP measurement, indicating that the finding is not attributable to measurement bias in biomarkers.

Expanding the social cure: a mixed-methods approach exploring the role of online group dance as support for young people (aged 16-24) living with anxiety.

There is an increased interest in whether online arts interventions support mental health and social connections. This study explored eight weeks of online group dance as support for young people (aged 16-24) living with anxiety. The applicability of the 'social cure' theoretical framework to the novel context of an online dance class was sought. The study utilised an embedded QUAL+quan design, incorporating participatory focus group discussions (n = 3 groups; n = 11 participants) and one-on-one interviews (n = 2 participants), creative reflections (n = 16 participants) and ethnographic fieldnotes, and a repeated measures design with surveys at three timepoints (week 1, n = 27; week 4, n = 18; week 8, n = 14). Thematic analysis identified two overarching themes demonstrating how the dance classes (i) provided the opportunity to co-construct a meaningful shared identity and (ii) supported holistic wellbeing. The quantitative findings supported this, suggesting lower anxiety, depression, and loneliness and higher wellbeing, self-esteem, self-efficacy, and group closeness. This study expands the social cure to its application to an online dance context for the first time.

Group singing in bereavement: effects on mental health, self-efficacy, self-esteem and well-being.

OBJECTIVES: Bereavement is associated with negative affective, cognitive, behavioural and physiological responses. However, factors, such as coping, self-efficacy and self-esteem, can buffer negative effects of grief, and can be increased through mutual support interventions, such as shared leisure activities. This study used a non-randomised controlled design to explore the effects of group choir singing on mental health among people who have been bereaved due to cancer. METHODS: A total of 58 adults bereaved in the last 5 years who had not started psychological therapy in the last 12 weeks or medication for anxiety or depression in the last month were recruited and elected to join a choir (n=29) or participate in the non-intervention control group (n=29). Joining a choir involved engaging in 90 min weekly singing and social sessions for 12 weeks with a post-intervention assessment at week 24. We used linear mixed effects models adjusted for demographics, health-related variables, musical engagement and time since bereavement to model changes over time between the two groups in symptoms of anxiety, depression, well-being, self-efficacy and self-esteem. RESULTS: Participants who sang in a choir had more stable symptoms of depression and levels of well-being, as well as gradual improvements in their sense of self-efficacy and self-esteem over the 24 weeks. In contrast, those in the control group showed gradual increases in depressive symptoms, reductions in levels of well-being and self-esteem and no improvement in their self-efficacy. These results were independent of all covariates. CONCLUSIONS: Weekly group singing could be a promising mutual support intervention for people experiencing grief.

How leisure activities affect health: a narrative review and multi-level theoretical framework of mechanisms of action.

There is a large and growing body of evidence on the health benefits of engagement in leisure activities (voluntary, enjoyable non-work activities, such as hobbies, arts, volunteering, community group membership, sports, and socialising). However, there is no unifying framework explaining how leisure activities affect health: what the mechanisms of action are by which engagement with leisure activities leads to the prevention, management, or treatment of mental and physical illness. In this Review, we identify and map over 600 mechanisms of action. These mechanisms can be categorised as psychological, biological, social, and behavioural processes that operate at individual (micro), group (meso), and societal (macro) levels, and are synthesised into a new theoretical framework: the Multi-level Leisure Mechanisms Framework. This framework situates understanding of leisure activities within the theoretical lens of complex adaptive systems and aims to support the design of more theory-driven, cross-disciplinary studies.

Psychosocial singing interventions for the mental health and well-being of family carers of patients with cancer: results from a longitudinal controlled study.

OBJECTIVE: The mental health challenges facing people who care for somebody with cancer are well documented. While many support interventions focus on provision of information or cognitive behavioural therapy, the literature suggests that psychosocial interventions could also be of value, especially given the low social support frequently reported by carers. Singing is a psychosocial activity shown to improve social support, increase positive emotions, and reduce fatigue and stress. This study explored whether weekly group singing can reduce anxiety, depression and well-being in cancer carers over a 6-month period. DESIGN: A multisite non-randomised longitudinal controlled study. SETTING: The Royal Marsden National Health Service Trust in Greater London. PARTICIPANTS: 62 adults who currently care for a spouse, relative or close friend with cancer who had not recently started any psychological therapy or medication. INTERVENTIONS: On enrolment, participants selected to join a weekly community choir for 12 weeks (n=33) or continue with life as usual (n=29). OUTCOME MEASURES: The primary outcome was mental health using the Hospital Anxiety and Depression Scale. The secondary outcome was well-being using the Warwick Edinburgh Mental Wellbeing Scale. Using linear mixed effects models, we compared the change in mental health and well-being over time between the two groups while adjusting for confounding variables including demographics, health-related variables, musical engagement and length of time caring. RESULTS: Participants in the choir group showed a significantly greater decrease in anxiety over time than participants in the control group (B=-0.94, SE=0.38, p=0.013) and a significantly greater increase in well-being (B=1.25, SE=0.49, p=0.011). No changes were found for depression. Sub-group analyses showed carers with anxiety or below-average well-being were most likely to benefit. CONCLUSIONS: This study builds on previous research showing the mental health benefits of singing for people with cancer by showing that weekly singing can also support anxiety and well-being in cancer carers.

The biological impact of listening to music in clinical and nonclinical settings: A systematic review.

This systematic review explored the evidence base on the impact of listening to music on biological response in both clinical and nonclinical settings. Human studies exploring the effects of listening to recorded music on biological markers were included. Studies had to involve a non-music control condition. Keyword searches were carried out of five major databases (Cochrane/Wiley, PsycINFO, PubMed, Sage, and Science Direct) and bias was assessed using the Cochrane Risk of Bias Tool for Randomized Studies (RoB 2.0). Forty-four studies assessing the biological impact of music listening were identified: 27 in clinical settings and 17 in nonclinical settings. Eighty-two percent had examined the effects of short-term listening interventions, while the remainder had looked at longitudinal interventions. Thirteen of 33 biomarkers tested were reported to change in response to listening to music. The most commonly analyzed biomarker was the stress hormone cortisol, with half of clinical studies demonstrating a stress-reducing effect of music listening. Blood glucose was also found repeatedly to reduce in response to music listening. Many of the other biomarkers analyzed are also part of biological stress pathways, which suggests that the primary way by which music listening affects us biologically is via modulations of stress response. Effects were shown irrespective of genre, self-selection of the music, or duration of listening, although a majority did use classical music. The evidence base for understanding biological responses to music is still developing, but there is support for the application of listening to music, especially within clinical settings for stress reduction.

What is the evidence on the role of the arts in improving health and well-being? A scoping review

Over the past two decades, there has been a major increase in research into the effects of the arts on health and well-being, alongside developments in practice and policy activities in different countries across the WHO European Region and further afield. This report synthesizes the global evidence on the role of the arts in improving health and well-being, with a specific focus on the WHO European Region. Results from over 3000 studies identified a major role for the arts in the prevention of ill health, promotion of health, and management and treatment of illness across the lifespan. The reviewed evidence included study designs such as uncontrolled pilot studies, case studies, small-scale cross-sectional surveys, nationally representative longitudinal cohort studies, community-wide ethnographies and randomized controlled trials from diverse disciplines. The beneficial impact of the arts could be furthered through acknowledging and acting on the growing evidence base; promoting arts engagement at the individual, local and national levels; and supporting cross-sectoral collaboration.
