Background: Many countries have restricted public life in order to contain the spread of the novel coronavirus (SARS-CoV2). As a side effect of related measures, physical activity (PA) levels may have decreased.
Objective: We aimed (1) to quantify changes in PA and (2) to identify variables potentially predicting PA reductions.
Methods: A systematic review with random-effects multilevel meta-analysis was performed, pooling the standardized mean differences in PA measures before and during public life restrictions.
Results: A total of 173 trials with moderate methodological quality (modified Downs and Black checklist) were identified. Compared to pre-pandemic, total PA (SMD − 0.65, 95% CI − 1.10 to − 0.21) and walking (SMD − 0.52, 95% CI − 0.29 to − 0.76) decreased while sedentary behavior increased (SMD 0.91, 95% CI: 0.17 to 1.65). Reductions in PA affected all intensities (light: SMD − 0.35, 95% CI − 0.09 to − 0.61, p = .013; moderate: SMD − 0.33, 95% CI − 0.02 to − 0.6; vigorous: SMD − 0.33, − 0.08 to − 0.58, 95% CI − 0.08 to − 0.58) to a similar degree. Moderator analyses revealed no influence of variables such as sex, age, body mass index, or health status. However, the only continent without a PA reduction was Australia and cross-sectional trials yielded higher effect sizes (p < .05).
Conclusion: Public life restrictions associated with the COVID-19 pandemic resulted in moderate reductions in PA levels and large increases in sedentary behavior. Health professionals and policy makers should therefore join forces to develop strategies counteracting the adverse effects of inactivity.
Governments have restricted public life during the COVID-19 pandemic, inter alia closing sports facilities and gyms. As regular exercise is essential for health, this study examined the effect of pandemic-related confinements on physical activity (PA) levels. A multinational survey was performed in 14 countries. Times spent in moderate-to-vigorous physical activity (MVPA) as well as in vigorous physical activity only (VPA) were assessed using the Nordic Physical Activity Questionnaire (short form). Data were obtained for leisure and occupational PA pre- and during restrictions. Compliance with PA guidelines was calculated based on the recommendations of the World Health Organization (WHO). In total, n = 13,503 respondents (39 ± 15 years, 59% females) were surveyed. Compared to pre-restrictions, overall self-reported PA declined by 41% (MVPA) and 42.2% (VPA). Reductions were higher for occupational vs. leisure time, young and old vs. middle-aged persons, previously more active vs. less active individuals, but similar between men and women. Compared to pre-pandemic, compliance with WHO guidelines decreased from 80.9% (95% CI: 80.3–81.7) to 62.5% (95% CI: 61.6–63.3). Results suggest PA levels have substantially decreased globally during the COVID-19 pandemic. Key stakeholders should consider strategies to mitigate loss in PA in order to preserve health during the pandemic.
While prospect of tracking mobile devices' users is widely discussed all over European countries to counteract COVID-19 propagation, we propose a Bloom filter based construction providing users' location privacy and preventing mass surveillance.
We apply a solution based on Bloom filters data structure that allows a third party, a government agency, to perform some privacy-preserving set relations on a mobile telco's access logfile.
By computing set relations, the government agency, given the knowledge of two identified persons, has an instrument that provides a (possible) infection chain from the initial to the final infected user no matter at which location on a worldwide scale they are.
The benefit of our approach is that intermediate possible infected users can be identified and subsequently contacted by the agency. With such approach, we state that solely identities of possible infected users will be revealed and location privacy of others will be preserved. To this extent, it meets General Data Protection Regulation (GDPR)requirements in this area.
This paper gives an overview of the impact that the corona pandemic has on the export industry in Canada and analyzes the different Canadian government measures for exporters. In addition, the measures are subsequently evaluated in order to identify if the support measures can help Canadian exporters to overcome the crisis. The basis of this paper are semi-structured expert interviews with experts from the financial sector, scientific literature and studies. The results have shown that the COVID-19 pandemic has a major impact on Canada’s export economy and it’s GDP. Trade is only possible to a limited extent, as many borders are closed. The Canadian government reacted with an economic response plan to support Canadian individuals and businesses. This paper depicts and assesses the most eligible measures for export companies.
In pandemic times, the possibilities for conventional sports activities are severely limited; many sports facilities are closed or can only be used with restrictions. To counteract this lack of health activities and social exchange, people are increasingly adopting new digital sports solutions—a behavior change that had already started with the trend towards fitness apps and activity trackers. Existing research suggests that digital solutions increase the motivation to move and stay active. This work further investigates the potentials of digital sports incorporating the dimensions gender and preference for team sports versus individual sports. The study focuses on potential users, who were mostly younger professionals and academics. The results show that the SARS-CoV-19 pandemic had a significant negative impact on sports activity, particularly on persons preferring team sports. To compensate, most participants use more digital sports than before, and there is a positive correlation between the time spent physically active during the pandemic and the increase in motivation through digital sports. Nevertheless, there is still considerable skepticism regarding the potential of digital sports solutions to increase the motivation to do sports, increase performance, or raise a sense of team spirit when done in groups.
Africa was the last region to witness significant spread of the COVID-19. Nonetheless, it was expected that the continent would be hardest hit due to the fragility of its health and social infrastructure as well as the vulnerability of its economies. While the rates of infection and death were initially relatively low and contained economically, the continent was hard hit early on. Cuts in credit and trade services by international banks, along with a decline in export earnings, tourism receipts, and inward remittances, have severely constrained the ability of African countries to finance imports of essential goods and to service maturing debt obligations.
However, Africa has over time created mechanisms and institutions to help cushion its economies from the adverse consequences of global shocks. Among these institutions is Afreximbank, which emerged out of the debt crisis of the 1980s. This paper presents an overview of the Bank’s support to African countries in dealing with two major derivatives of the COVID-19 pandemic: the trade finance challenges resulting from cuts in international financial flows to the continent, and the health consequences of the pandemic.
This essay is about Estonia’s measures to help its exporters responding to COVID-19. The purpose is to analyse the companies’ need for help measures and the governmental objectives behind the measures and finally to analyse the possible effects. We used the two latest surveys dealing with the entrepreneurship situation and conducted two inter-views with governmental representatives exposing their objectives. The outcomes show that more than half of Estonian companies are asking for governmental help mainly as a consequence of a drop of demand. Limiting the increase of unemployment and bankrupt-cies as well as strengthening the economic recovery were identified as the main govern-mental objectives while restraining fiscal costs is a subordinated objective but becomes more important the more money will be spent. The help measures offered by KredEx are in line with these objectives. After the crisis the implications of the established measures should be analysed so that others can learn from the Estonian Government’s approach.
Due to the pandemic of 2020, many teaching and research institutions are confronted with extraordinary working conditions. In order to enable empirical data collection under these special circumstances, teachers and scientists need to respond flexibly and new concepts need to be developed. This paper deals with the challenges that arise in day-to-day teaching and provides different approaches to meet these challenges. It covers quantitative surveys, remote UX-testing methods as an alternative to eye tracking studies in the lab, as well as face-to-face user experience testings under strict hygiene measures.
This essay deals with the Spanish economy and especially with the Spanish governmental measures for SME exporters in times of COVID-19. The focus was set on SMEs, as they are an essential part of trade for the government and are particularly affected by the pandemic. Since the financial crisis, the Spanish economy has become highly diversified, with a greater focus on exports. Competitiveness, productivity and efficiency have increased significantly. The Spanish government measures largely affect the areas liquidity and financing, taxes and protection of the employment. One of the most important measures is the 100-billion-euro credit line and the policies on unemployment. The Spanish government is dependent on further aid packages and is criticized for the measures.
