United we thrive: friendship and subsequent physical, behavioural and psychosocial health in older adults (an outcome-wide longitudinal approach)
CONCLUSIONS: Our findings indicate that stronger friendships can have a dual impact on health and well-being. While stronger friendships appear to mainly promote a range of health and well-being outcomes, stronger friendships might also promote negative outcomes. Additional research is needed, and any future friendship interventions and policies that aim to enhance outcomes should focus on how to amplify positive outcomes while mitigating harmful ones.PMID:37964589 | DOI:10.1017/S204579602300077X (Source: Epidemiology and Psychiatric Sciences)

Seasonal patterns of sickness absence due to diagnosed mental disorders: a nationwide 12-year register linkage study
CONCLUSIONS: These results suggest a seasonal variation in sickness absence due to common mental disorders and bipolar disorder, with high peaks in depressive, anxiety and sleep disorders towards the end of the year and a peak in manic episodes starting in spring. Rapid changes in light exposure may contribute to sickness absence due to bipolar disorder. The findings can help clinicians and workplaces prepare for seasonal variations in healthcare needs.PMID:37941381 | DOI:10.1017/S2045796023000768 (Source: Epidemiology and Psychiatric Sciences)

Changing trends in the global burden of mental disorders from 1990 to 2019 and predicted levels in 25 years
CONCLUSIONS: Although the age-standardized burden of mental disorders has declined in the past 30 years, the number of new cases and deaths of mental disorders worldwide has increased, and will continue to increase in the near future. Therefore, relevant policies should be used to promote the prevention and management of known risk factors and strengthen the understanding of risk profiles and incidence modes of mental disorders, to help guide future research on control and prevention strategies.PMID:37933540 | DOI:10.1017/S2045796023000756 (Source: Epidemiology and Psychiatric Sciences)
