The effect of exercise and affect regulation skills on mental health during the COVID-19 pandemic: A cross-sectional survey.

BACKGROUND: COVID-19-related confinements pose a threat to mental health. We investigated prevalence rates of symptoms of depression, generalized anxiety and insomnia in German adults. Furthermore, we explored associations of exercise behavior with disorder-specific symptoms and assessed whether specific affect regulation skills enhance the effect of exercise on symptom alleviation. METHODS: Cross-sectional survey-based data collected during the first lockdown is presented: 4268 adults completed questionnaires on mental health, exercise behavior and Covid-related lifestyle factors. Primary outcome was depression (PHQ-9), secondary outcomes generalized anxiety (PHQ-D) and sleep quality (PSQI). Multiple linear regression analyses were performed to examine the association of exercise behavior with the outcomes. RESULTS: Analyses resulted in elevated symptoms of psychological distress (probable cases of depressive disorder: 31.2%, anxiety disorder: 7.5%, sleeping disorder: 43.0%). A change towards less exercise during the lockdown was significantly associated with higher levels of depression (t=5.269; ß=0.077, p<.001), anxiety (t=3.397; ß=0.055, p<.001) and insomnia (t=3.466; ß=0.058; p<.001). Physical activity (PA)-related affect regulation enhanced the effect of exercise on mental health. CONCLUSION: Results suggest a demand for measures which promote the maintenance of exercise during a pandemic and improve PA-related affect regulation to optimize effects of exercise on mental health.

Acute appendicitis during the COVID-19 pandemic-changes in incidence and clinical presentation but not in patients' outcome.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is an ongoing severe issue. OBJECTIVE: The aim of this study was to compare the incidence, severity and treatment of acute appendicitis (AA) before and during the COVID-19 pandemic. METHODS: A retrospective cohort analysis was conducted between January 2019 and April 2020 in one high-volume center. A comparison was performed between two groups (Group A: patients admitted with AA before the COVID-19 pandemic; Group B: patients admitted with AA at the beginning of the pandemic) in terms of the incidence of AA and clinical and pathological outcomes. The incidence of AA was also analyzed in six surrounding peripheral hospitals. RESULTS: A total of 94 patients were identified, 54 in Group A and 40 in Group B (57% vs. 43%). Demographic data were comparable between groups. AA in Group B showed a significant higher rate of histological advanced cases (10 (18.5%) Group A vs. 20 (50%) Group B, P = 0.001) and the need for postoperative antibiotic treatment (6 (11.1%) Group A vs. 11 (27.5%) Group B, P = 0.045). During the pandemic, a higher percentage of patients were treated at peripheral hospitals (Group A: 54/111 vs. 40/126). CONCLUSION: During the onset of the COVID-19 pandemic there was a significant decrease of patients with AA in a high-volume center, which showed more advanced disease of AA. This significant decrease in the high-volume center correlates with an increase in patients with AA in peripheral hospitals and represents a change in patient flow during the onset of the pandemic.

Is Physical Activity Associated with Less Depression and Anxiety During the COVID-19 Pandemic? A Rapid Systematic Review.

BACKGROUND: The Covid-19 pandemic is affecting the entire world population. During the first spread, most governments have implemented quarantine and strict social distancing procedures. Similar measures during recent pandemics resulted in an increase in post-traumatic stress, anxiety and depression symptoms. The development of novel interventions to mitigate the mental health burden are of utmost importance. OBJECTIVE: In this rapid review, we aimed to provide a systematic overview of the literature with regard to associations between physical activity (PA) and depression and anxiety during the COVID-19 pandemic. DATA SOURCE: We searched major databases (PubMed, EMBASE, SPORTDiscus, and Web of Science) and preprint servers (MedRxiv, SportRxiv, ResearchGate, and Google Scholar), for relevant papers up to 25/07/2020. STUDY ELIGIBILITY CRITERIA: We included observational studies with cross-sectional and longitudinal designs. To qualify for inclusion in the review, studies must have tested the association of PA with depression or anxiety, using linear or logistic regressions. Depression and anxiety must have been assessed using validated rating scales. STUDY APPRAISAL AND SYNTHESIS METHODS: Effect sizes were represented by fully adjusted standardized betas and odds ratios (OR) alongside 95% confidence intervals (CI). In case standardized effects could not be obtained, unstandardized effects were presented and indicated. RESULTS: We identified a total of 21 observational studies (4 longitudinal, 1 cross-sectional with retrospective analysis, and 16 cross-sectional), including information of 42,293 (age 6-70 years, median female = 68%) participants from five continents. The early evidence suggests that people who performed PA on a regular basis with higher volume and frequency and kept the PA routines stable, showed less symptoms of depression and anxiety. For instance, those reporting a higher total time spent in moderate to vigorous PA had 12-32% lower chances of presenting depressive symptoms and 15-34% of presenting anxiety. CONCLUSION: Performing PA during Covid-19 is associated with less depression and anxiety. To maintain PA routines during Covid-19, specific volitional and motivational skills might be paramount to overcome Covid-19 specific barriers. Particularly, web-based technologies could be an accessible way to increase motivation and volition for PA and maintain daily PA routines.
