Experience of loneliness during the COVID-19 pandemic: a cross-sectional study of 50 968 adult Danes

Music-Making and Depression and Anxiety Before and During the COVID-19 Pandemic-Results From the NAKO Cohort Study in Germany

Objectives

To investigate the association of musical activity with mental health during the COVID-19 pandemic.

Methods

A total of 3,666 participants reported their musical activity before and mental health indicators before and during the pandemic. Depression was assessed with the Patient Health Questionnaire, anxiety with the Generalized Anxiety Disorder scale. The association between mental health scores and musical activities was investigated using linear regression.

Results

Within the last 12 months, 22.1% of the participants reported musical activity (15.1% singing, 14.5% playing an instrument). Individuals with frequent singing as their main musical activity had higher scores before the pandemic than non-musicians and the worsening during the pandemic was more pronounced compared to non-musicians. Instrumentalists tended to have slightly lower scores than non-musicians indicating a possible beneficial effect of playing an instrument on mental health.

Conclusion

The pandemic led to a worsening of mental health, with singers being particularly affected. Singers showed poorer mental health before the pandemic. The tendency for instrumentalists to report lower depression scores compared to non-musicians may support the hypothesis that music-making has a beneficial effect on health.

Meditation Moderates the Relationship between Insecure Attachment and Loneliness: A Study of Long-Term Care Residents in Thailand

Background and Objectives: Loneliness is prevalent among residents of long-term care settings, posing significant challenges to their mental wellbeing. Insecure attachment has been identified as a contributing factor to loneliness in this population. Previous research has suggested that meditation may have beneficial effects on mental health outcomes. This study aimed to examine the relationship between meditation, insecure attachment, and loneliness among residents of long-term care facilities in Thailand. Specifically, the study sought to investigate the moderating effect of meditation on the association between insecure attachment (both avoidance and anxiety) and loneliness. Materials and Methods: A cross-sectional study was conducted involving 236 residents living in long-term care homes in Thailand. Participants completed self-report measures including the 18-item Revised Experience of Close Relationship questionnaire (to assess attachment anxiety and avoidance), the Inner Strength-Based Inventory (to measure meditation practice), and the 6-item Revised Version of the University of California Los Angeles Loneliness Scale. Moderation analyses were performed to explore the role of meditation in the relationship between insecure attachment and loneliness. Results: The mean age of participants was 73.52 years, with females accounting for 57.6% of the sample. Among the participants, 58.4% reported engaging in meditation, with practice frequency ranging from often to daily. The mean meditation score was 2.92 out of 5, indicating regular but not daily practice. Meditation was found to moderate the relationship between insecure attachment (both avoidance and anxiety) and loneliness. Specifically, the moderation effect between attachment anxiety and loneliness was significant (B = 0.44, SE = 0.21, 95% CI [0.30, 0.86]), as was the interaction effect between attachment anxiety and loneliness (B = -0.34, SE = 0.17, 95% CI [-0.67, -0.02]). Conclusions: The findings suggest that the impact of meditation practice on loneliness is influenced by an individual's attachment dimension. Meditation demonstrates a moderating effect on attachment avoidance, anxiety, and loneliness, with variations observed in the direction of these effects. The clinical implications of these findings and recommendations for further research are discussed.

A genome-wide association study of social trust in 33,882 Danish blood donors

Social trust is a heritable trait that has been linked with physical health and longevity. In this study, we performed genome-wide association studies of self-reported social trust in n = 33,882 Danish blood donors. We observed genome-wide and local evidence of genetic similarity with other brain-related phenotypes and estimated the single nucleotide polymorphism-based heritability of trust to be 6% (95% confidence interval = (2.1, 9.9)). In our discovery cohort (n = 25,819), we identified one significantly associated locus (lead variant: rs12776883) in an intronic enhancer region of PLPP4, a gene highly expressed in brain, kidneys, and testes. However, we could not replicate the signal in an independent set of donors who were phenotyped a year later (n = 8063). In the subsequent meta-analysis, we found a second significantly associated variant (rs71543507) in an intergenic enhancer region. Overall, our work confirms that social trust is heritable, and provides an initial look into the genetic factors that influence it.
