Doctoral Researchers (DRs) are an important part of the academic community and, after graduating, make substantial social and economic contributions. Despite this importance, DR wellbeing has long been of concern. Recent studies have concluded that DRs may be particularly vulnerable to mental health problems, yet direct comparisons of the prevalence of mental health problems between this population and control groups are lacking. Here, by comparing DRs with educated working controls, we show that DRs report significantly greater anxiety and depression, and that this difference is not explained by a higher rate of pre-existing mental health problems. Moreover, most DRs perceive poor mental health as a ‘normal’ part of the PhD process. Thus, our findings suggest a hazardous impact of PhD study on mental health, with DRs being particularly at risk of developing common mental health problems. This provides an evidence-based mandate for universities and funders to reflect upon practices related to DR training and mental health. Our attention should now be directed towards understanding what factors may explain heightened anxiety and depression among DRs so as to inform preventative measures and interventions.

Wetland parks are designed to support urban ecological protection, flood control and human well-being. Existing research mainly focuses on their influence on ecology and economy. However, their influence on human well-being and health is rarely studied. In China, during the peak of the COVID-19 pandemic (Peak), people were very concerned about health, while at the same time wetland parks which are generally considered beneficial to health were closed. Thus, this study explores the public’s perception of the health effects of visiting wetland parks and the impact of the pandemic on the perception. From March 5th to 8th, 2020, before the Peak in China was over, 1,400 respondents participated in a nationwide online survey. It was found that the perceived benefits from visiting wetland parks were higher in terms of mental health than in physical health. Also, the perceived health benefits of wetland parks after the Peak were slightly higher than before the pandemic. The results highlight that wildlife habitat services were considered to be the most important ecosystem services that promote the perceived health benefits. Interestingly, the perceived health benefits of wetland parks by health experts appear to be lower than in other groups, indicating that the health benefits of visiting wetland parks may be overestimated by lay-people or underestimated by health experts. The results provide empirical evidence for managing ecosystem services as delivered by these urban wetlands, in the context of COVID-19 or potential future pandemics, for promoting public health.

The COVID-19 pandemic has introduced a myriad of challenges to the social life and care of people with Parkinson’s disease (PD), which could potentially worsen mental health problems. We used baseline data of the PRIME-NL study (N = 844) to examine whether the association between COVID-19 stressors and mental health is disproportionately large in specific subgroups of people with PD and to explore effects of hypothetical reductions in COVID-19 stressors on mental health and quality of life. The mean (SD) age of the study population was 70.3 (7.8) years and 321 (38.0%) were women. The linear regression effect estimate of the association of COVID-19 stressors with mental health was most pronounced in women, highly educated people, people with advanced PD and people prone to distancing or seeking social support. Smaller effect estimates were found in people scoring high on confrontive coping or planful problem solving. The parametric G-formula method was used to calculate the effects of hypothetical interventions on COVID-19 stressors. An intervention reducing stressors with 50% in people with above median MDS-UPDRS-II decreased the Beck Depression Inventory in this group from 14.7 to 10.6, the State-Trait Anxiety Inventory from 81.6 to 73.1 and the Parkinson’s Disease Quality of Life Questionnaire from 35.0 to 24.3. Insights from this cross-sectional study help to inform tailored care interventions to subgroups of people with PD most vulnerable to the impact of COVID-19 on mental health and quality of life.

Exercise addiction (EA) involves excessive concerns for exercise routines, an abusive practice, and the inability to control one’s own behavior, as well as the presence of psychological processes that are typical of behavioral addictions such as abstinence. EA is further associated with an alteration of the individual’s personal, social, and professional functioning and a higher risk for several pathologies, including physical injury, psychological distress, and eating disorders. The present work presents a narrative scoping review of the state of the art and the main findings of the research on EA, with a focus in the athletic population. The prevalence of EA risk, between 1 and 52% and up to 80% when co-occurring with eating disturbances, is also reviewed. Additionally, some of the explanatory models proposed to date and their power and limitations in terms of their capacity for a consensual operationalization and characterization of EA, and thus for the optimal exploration and management of this condition, are discussed. Finally, some deficiencies in the research on EA are noted which are to be addressed to successfully respond to the intervention and prevention needs that occur both in the general context of exercise-sports practice and the specific context of competitive athletes., CRUE-CSIC, Research Group CTS267 by Junta de Andalucía (Spain), Universidad de Granada/CBUA
