Impact of COVID-19 Pandemic Lockdown on Body Mass Index and Physical Fitness in Chinese College Students.

PURPOSE: To explore the impact of COVID-19 pandemic lockdown (CoPL) on body mass index (BMI) and physical fitness among college students. METHODS: Two one-year cohorts, one with no pandemic lockdown (NoPL) exposure and one with CoPL exposure, were included. Baseline measurements were performed in October 2018 (NoPL) and October 2019 (CoPL), and follow-up data were collected one year later. Participants were divided into "deterioration", "no-change", and "improvement" groups based on their quartile distribution of one-year differences (follow-up-baseline) for lower 25%, middle 50%, and upper 25%. Baseline-category logit regression models were used to determine the odds ratios of deterioration and improvement in BMI and physical fitness, with "no-change" used as baseline. RESULTS: A total of 2,594 and 2,525 students were included in NoPL and CoPL cohorts, respectively. CoPL was associated with higher odds for deterioration in BMI (male), explosive strength, upper-limb muscle strength, abdominal muscle strength, and cardiorespiratory fitness, but lower odds for deterioration in BMI (female) and flexibility. CoPL was associated with lower odds for improvement in BMI (male), explosive strength, lower-limb and upper-limb muscle strength, and cardiorespiratory fitness, but higher odds for improvement in BMI (female) and flexibility. DISCUSSION: Not all dimensions of health outcomes were negatively impacted by the lockdown, as deterioration in BMI in males, muscle strength, and cardiorespiratory fitness following the CoPL were more than that in the absence of the lockdown, while deterioration in BMI in females and flexibility were less than that in the absence of the lockdown.

Impact of working and learning from home during the COVID-19 pandemic on the head, the neck and orofacial health: A cross-sectional pilot study.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic, about 81% of the world's population moved their workplace to a home office. OBJECTIVES: The main objective of this cross-sectional pilot study was to determine the impact of working and/or learning from home during the COVID-19 pandemic on the head, the neck and orofacial health in university students, faculty and staff. MATERIAL AND METHODS: Participants from 4 universities were recruited for an online survey. The survey included 33 questions related to demographics, health issues before and during the lockdown, work/study from home, and the awareness of the health effects of the lockdown. Descriptive statistics and single logistic regression analysis were employed. RESULTS: A total of 96 subjects aged 26 ±10.5 years participated in the study. Of these, 60% did not consider their home workstation to be adequate. The development of new symptoms or the worsening of the pre-existing symptoms was observed in 67%, 24%, 59%, and 37% of the participants with regard to neck pain, temporomandibular joint (TMJ)-related issues, headaches, and parafunctional oral habits, respectively. In addition, 87% of the respondents reported that their oral habits were aggravated by neck pain and a bad posture. As compared to the faculty and the staff, the students were more likely to experience headaches or the exacerbation of the pre-existing headaches during the pandemic. In the survey, 91% of the participants reported an increased awareness of the impact of the lockdown on their head and neck, and orofacial health. CONCLUSIONS: The present study helps understand the self-perceived effects of working and/or learning from home during the COVID-19 pandemic, and may facilitate implementing the appropriate models of treatment of the craniocervical-mandibular region during a pandemic.

Reflections on the process, challenges, and lessons learned conducting remote qualitative research on Violence against women during COVID-19 pandemic lockdown in South Africa.

BACKGROUND: Violence against women (VAW) research is a sensitive topic, which has been conducted mainly using face-to-face methods. The COVID-19 pandemic lockdown and restrictions on movement presented an opportunity to conduct VAW research using remote methods. We discuss how we adapted methods, reflect on lessons learned, and make recommendations highlighting key considerations when conducting remote research on a sensitive topic of VAW. METHODS: We designed and conducted an exploratory qualitative study using remote methods with 18 men and 19 women, aged 18 years and older, who lived with their partner or spouse during lockdown in South Africa. The aim of the study was to explore experiences of COVID-19 lockdown, and its link to women and children's experiences of violence in the homes. Data presented in this paper draws from researchers' reflections drawn from debriefing sessions during the research process, and from participants' interview transcripts. FINDINGS: Remote recruitment of participants took longer than anticipated, and we had to re-advertise the study. We could not ensure safety and privacy during interviews. Regardless of all the safety and privacy measures we put in place during the research process, some participants had an adult person present in the room during interviews, and the researchers had no control over interruptions. Rapport was difficult to establish without an in-person connection, which limited disclosure about violence experience (amongst women) and perpetration (amongst men). CONCLUSIONS: Given the methodological and ethical challenges which limited disclosure of VAW remotely, we conclude that telephone interviews used in our study impacted on the quality of study data. Therefore, we do not recommend VAW research to be conducted remotely, unless it is essential and participants are already known to the interviewer and trust has been established.

The effects of lockdown during the COVID-19 pandemic on fetal movement profiles.

PURPOSE: The current study investigated the direct impact of the COVID-19 lockdown on fetal movements, addressing a critical research gap. While previous research has predominantly examined the effects of lockdown on maternal health and postnatal outcomes, little attention has been paid to the direct consequences on fetal well-being as indicated by their movement profile. METHODS: We conducted analysis of movement profiles in 20 healthy fetuses during the COVID-19 pandemic lockdown (third national UK lockdown period between January and March 2021) and compared them with 20 healthy fetuses from pre-covid pregnancies, all at 32 weeks gestation. We controlled for maternal stress, depression, and anxiety. RESULTS: Pregnant mothers during pre-covid compared with those during the COVID-19 lockdown reported similar levels of stress (p = 0.47), depression (p = 0.15), and anxiety (p = 0.07). Their fetuses, however, differed in their movement profiles with mouth movement frequencies significantly higher during COVID-19 lockdown (COVID-19 lockdown: mean of 5.909) compared to pre-Covid pregnancies (mean of 3.308; p = 0.029). Furthermore, controlling for maternal anxiety a regression analysis indicated that frequency of fetal mouth movements (p = 0.017), upper face movements (p = 0.008), and touch movements (p = 0.031) were all significantly higher in fetuses observed during lockdown compared to fetuses before the Covid period. CONCLUSION: Fetuses show an effect of lockdown independent of maternal anxiety, stress, or depression. These findings contribute to our understanding of fetal development during extraordinary circumstances, raising questions about the potential effects of having to stay indoors during lockdowns.

Global Otitis Media Incidence Changes During the COVID Pandemic: Systematic Review and Meta-Analysis.

OBJECTIVE: The aim was to analyze the global impact of the COVID-19 pandemic and national lockdowns on the incidence of otitis media (OM), a common otolaryngologic disease. DATA SOURCES: PubMed, Scopus, and CINAHL. REVIEW METHODS: A systematic review and meta-analysis were performed using PRISMA reporting guidelines. OM incidence (measured as newly diagnosed OM cases over total patients seen over a time period), OM antibiotic prescriptions (OM cases for which antibiotics were prescribed over total OM cases), and tympanostomy tube surgeries (all tympanostomy tube surgeries over total surgical cases) were extracted. Meta-analysis of proportions and comparison of proportions were performed. RESULTS: Of 1004 studies screened, 26 studies in 11 countries met inclusion criteria. The percentages of OM cases pre- and during-lockdown were 6.67%, 95% CI [4.68%, 8.99%], and 2.63% [2.02%, 3.31%], respectively, with an OR of 0.31 favoring during-lockdown [0.25, 0.39] (p < 0.00001). Antibiotic prescriptions per all OM episodes pre- and during-lockdown were 1.61% [0.17%, 8.46%] and 0.62% [0.07%, 3.32%], with an OR of 0.37 favoring during-lockdown ([0.35, 0.40], p < 0.00001). Tympanostomy tube surgery proportions pre- and during-lockdown were 31.64% [6.85%, 64.26%] and 29.99% [4.14%, 66.55%], with an OR of 0.94 favoring neither during- nor pre-lockdown [0.45, 2.00] (p = 0.88). CONCLUSION: The incidence of OM decreased significantly following international lockdowns due to the COVID-19 pandemic, with antibiotic prescriptions for OM episodes showing a corresponding decrease. Despite these reductions, numbers of tympanostomy tube procedures did not change significantly. These reductions are likely due to social distancing, decreased exposure through high transmission facilities such as day cares, decreased health care utilization, and even possibly decreased air pollution.

COVID-19 pandemic impact among adolescents with eating disorders referred to Italian psychiatric unit.

PROBLEM: The COVID-19 pandemic has triggered or exacerbated eating disorders (EDs), especially in adolescents. This study examined the prevalence of admissions of patients with EDs at the Child and Adolescent Psychiatry Unit from the pre-COVID-19 pandemic to March 2023 and explored the differences in dimensions of ED's symptomatology according to the year of access. METHODS: We included 174 children and adolescents, 94.3% females and 5.7% males, with a diagnosis of ED (Mage = 14.87; SD = 1.72). The Eating Disorder Inventory-3 (EDI-3), the Body Uneasiness Test (BUT) and Youth Self Report ASEBA (YSR) were assessed. A one-way analysis of variance test was performed. FINDINGS: EDs' hospitalization prevalence was higher in the years 2020 and 2021 compared to pre-COVID-19 and the year 2022. Considering the ED psychopathology (EDI-3), findings showed a higher score in the dimension of the push to thinness, body dissatisfaction, asceticism, and fear of maturity in the year 2021 compared to pre-pandemic. Regarding the discomfort related to the image of one's own body (BUT), results showed an increase in the global severity index in the year 2022 compared to pre-pandemic and in weight phobia in the year 2021 compared to the year 2020. Concerning the internalizing symptoms (YSR), a tendency was found for withdrawal/depression, with higher levels in the year 2022 compared to the year 2020. CONCLUSIONS: Our study highlighted the increase of different types of EDs symptomatology related to concerns about weight, especially 2 and 3 years after the outbreak of the pandemic, on which the literature is still scarce, especially in the Italian context.

Anthropogenic activity, hydrological regime, and light level jointly influence temporal patterns in biosonar activity of the Yangtze finless porpoise at the junction of the Yangtze River and Poyang Lake, China.

Under increasing anthropogenic pressure, species with a previously contiguous distribution across their ranges have been reduced to small fragmented populations. The critically endangered Yangtze finless porpoise ( Neophocaena asiaeorientalis asiaeorientalis), once commonly observed in the Yangtze River-Poyang Lake junction, is now rarely seen in the river-lake corridor. In this study, static passive acoustic monitoring techniques were used to detect the biosonar activities of the Yangtze finless porpoise in this unique corridor. Generalized linear models were used to examine the correlation between these activities and anthropogenic impacts from the COVID-19 pandemic lockdown and boat navigation, as well as environmental variables, including hydrological conditions and light levels. Over approximately three consecutive years of monitoring (2020-2022), porpoise biosonar was detected during 93% of logged days, indicating the key role of the corridor for finless porpoise conservation. In addition, porpoise clicks were recorded in 3.80% of minutes, while feeding correlated buzzes were detected in 1.23% of minutes, suggesting the potential existence of localized, small-scale migration. Furthermore, both anthropogenic and environmental variables were significantly correlated with the diel, lunar, monthly, seasonal, and annual variations in porpoise biosonar activities. During the pandemic lockdown period, porpoise sonar detection showed a significant increase. Furthermore, a significant negative correlation was identified between the detection of porpoise click trains and buzzes and boat traffic intensity. In addition to water level and flux, daylight and moonlight exhibited significant correlations with porpoise biosonar activities, with markedly higher detections at night and quarter moon periods. Ensuring the spatiotemporal reduction of anthropogenic activities, implementing vessel speed restrictions (e.g., during porpoise migration and feeding), and maintaining local natural hydrological regimes are critical factors for sustaining porpoise population viability.

Changes in NO2 and O3 levels due to the pandemic lockdown in the industrial cities of Tehran and Arak, Iran using Sentinel 5P images, Google Earth Engine (GEE) and statistical analysis.

Air pollution has very damaging effects on human health. In recent years the Coronavirus disease (COVID-19) pandemic has created a worldwide economic disaster. Although the consequences of the COVID-19 lockdowns have had severe effects on economic and social conditions, these lockdowns also have also left beneficial effects on improving air quality and the environment. This research investigated the impact of the COVID-19 lockdown on NO2 and O3 pollutants changes in the industrial and polluted cities of Arak and Tehran in Iran. Based on this, the changes in NO2 and O3 levels during the 2020 lockdown and the same period in 2019 were investigated in these two cities. For this purpose, the Sentinel-5P data of these two pollutants were used during the lockdown period from November 19 to December 05, 2020, and at the same time before the pandemic from November 19 to December 05, 2019. For better results, the effect of climatic factors such as rain and wind in reducing pollution was removed. The obtained results indicate a decrease in NO2 and O3 levels by 3.5% and 6.8% respectively in Tehran and 20.97% and 5.67% in Arak during the lockdown of 2020 compared to the same time in 2019. This decrease can be caused by the reduction in transportation and socio-economic and industrial activities following the lockdown measures. This issue can be a solid point to take a step toward controlling and reducing pollution in non-epidemic conditions by implementing similar standards and policies in the future.

How perceived scarcity predicted cooperation during early pandemic lockdown.

Both material resources (jobs, healthcare), and socio-psychological resources (social contact) decreased during the COVID-19 pandemic. We investigated whether individual differences in perceived material and socio-psychological scarcity experienced during the pandemic predicted preference for cooperation, measured using two Public Good Games (PGGs), where participants contributed money or time (i.e., hours indoors contributed to shorten the lockdown). Material scarcity had no relationship with cooperation. Increased perceived scarcity of socio-psychological wellbeing (e.g., connecting with family) predicted increased preference for cooperation, suggesting that missing social contact fosters prosociality, whilst perceived scarcity of freedom (e.g., limited movement) predicted decreased willingness to spend time indoors to shorten the lockdown. The importance of considering individual differences in scarcity perception to best promote norm compliance is discussed.

Quantifying the impact of pandemic lockdown policies on global port calls.

The recent experience of lockdowns during COVID-19 highlights the prolonged impact a pandemic could have on ports and the shipping industry. This paper uses port call data derived from the Automatic Identification System (AIS) reports from the world's 30 largest container ports to quantify both the immediate and longer-term impact of national COVID-19 lockdown policies on global shipping flows. The analysis uses the Difference-in-Difference (DID) and combined regression discontinuity design (RDD)-DID models to represent the effects of lockdown policies. The combination of RDD and DID models is particularly effective because it can mitigate time trends in the data, e.g., the Chinese New Year effect on Chinese ports. This study further examines the potential shock propagation effects, namely, how lockdown policy in one country (i.e., China) can affect the number of port calls in other countries. We categorize ports in other countries into a high-connectivity (with Chinese ports) group and a low-connectivity group, using a proposed connectivity index with China derived from individual vessel trajectories obtained from the AIS data. The results provide a clearly measurable picture of the kinds of trade shocks and consequent pattern changes in port calls over time caused by responses to lockdown policies of varying levels of stringency. We further document the existence of significant shock propagation effects. As the risk of pandemics rises in the twenty-first century, these results can be used by policy makers to assess the potential impact of different levels of lockdown policy on the maritime industry and trade flows more broadly. Maritime players can also use findings such as these to manage their capacity during lockdowns more effectively and to respond more flexibly to changing demand in seaborne transportation.

COVID-19 Pandemic Impact on Undergraduate Nursing Students: A Cross-Sectional Study.

COVID-19 is a challenge for education systems around the world. This study aimed to evaluate the perceived impact of the COVID-19 pandemic on nursing students, by assessing their emotions, the level of concern in contracting the virus and their perceived stress. We conducted an observational cross-sectional study. A total of 709 nursing students completed an anonymous questionnaire. The levels of anxiety and stress were assessed using the generalized anxiety disorder scale and the COVID-19 student stress questionnaire, respectively. In total, 56.8% of the sample often or always found it difficult to attend distance-learning activities. The main difficulty referred to was connection problems (75.7%). The mean generalized anxiety disorder score was 9.46 (SD = 5.4) and appeared almost homogeneous among students across the three years of study; most of the students showed mild (35%) to moderate (27%) levels of anxiety; 19% had severe anxiety. The overall COVID-19 stressor mean scores were 11.40 (SD = 6.50); the majority of the students (47.1%) showed scores indicative of moderate stress, 25% showed low stress levels, and 28% showed high-stress levels. Improvements and investments are needed to ensure high-quality distance learning, adequate connectivity, technical support for students, as well as strategies to promote mental health.

Sleep and Health-Related Characteristics among Adolescents during COVID-19: An Update.

Two opposing effects on adolescents' health during COVID-19 lockdown have been described: A beneficial one due to longer sleep times during school closures and a detrimental one of psychological distress. This study investigated how sleep and health changed in the course of the pandemic when schools were open again. Overall, 12,238 adolescents in Switzerland participated in three cross-sectional online surveys: In 2017 under regular conditions (control group), during pandemic school closures in 2020 (closure group), and in 2021 still under pandemic conditions, but schools were open again (postclosure group). Sleep behavior and health-related characteristics (health-related quality of life; caffeine, alcohol, and nicotine use) in all three groups and depressive symptoms in the closure and postclosure groups were assessed. The sleep period on school days was longer in the closure group (median 9.00 h, interquartile range 8.25-9.75) and similar in the postclosure (7.92, 7.00-8.50) compared to the control group (7.75, 7.08-8.33). Health-related characteristics were better during school closures and similar to worse in the postclosure compared to the control group. Depressive symptom levels were higher in the postclosure than in the closure group. Therefore, beneficial effects were specific to school closures and adolescents' psychological distress increased over the course of the pandemic.

Impacts of the COVID-19 lockdown on building energy consumption and indoor environment: A case study in Dalian, China.

Restricting social distancing is an effective means of controlling the COVID-19 pandemic, resulting in a sharp drop in the utilization of commercial buildings. However, the specific changes in the operating parameters are not clear. This study aims to quantify the impact of COVID-19 lockdowns on commercial building energy consumption and the indoor environment, including correlation analysis. A large green commercial building in Dalian, China's only country to experience five lockdowns, has been chosen. We compared the performance during the lockdown to the same period last year. The study found that the first lockdown caused a maximum 63.5% drop in monthly energy consumption, and the second lockdown was 55.2%. The energy consumption per unit area in 2020 dropped by 55.4% compared with 2019. In addition, during the lockdown, the compliance rate of indoor thermal environment increased by 34.7%, and indoor air quality was 9.5%. These findings could partly explain the short-term and far-reaching effects of the lockdown on the operating parameters of large commercial buildings. Humans are likely to coexist with COVID-19 for a long time, and commercial buildings have to adapt to new energy and health demands. Effective management strategies need to be developed.

Gender-Specific Related Factors for Suicidal Ideation During COVID-19 Pandemic Lockdown Among 5,175 Chinese Adolescents.

Background: Suicide was an urgent issue during the pandemic period in adolescents. However, few studies were focused on suicide during the coronavirus disease 2019 (COVID-19) pandemic lockdown. Methods: An online survey was conducted among 5,175 Chinese adolescents from June 9th to 29th in 2020 to investigate the prevalence of suicidal ideation (SI) during COVID-19 pandemic lockdown. A gender-specific stepwise logistic regression model was used. All analyses were performed with STATA 15.0. Results: About 3% of the participants had reported having SI during the COVID-19 pandemic lockdown period. The prevalence of female SI (3.64%, 95% CI: 2.97-4.45%) was higher than that of males (2.39%, 95% CI: 1.88-3.05%) (χ2 = 6.87, p = 0.009). Quarreling with parents [odds ratio (OR) = 9.73, 95% CI: 5.38-17.59], insomnia (OR = 5.28, 95% CI: 2.81-9.93), previous suicide attempt history (OR = 3.68, 95% CI: 1.69-8.03), previous SI history (OR = 2.81, 95% CI: 1.30-6.06), and feeling depressed during pandemic lockdown (OR = 2.26, 95% CI: 1.22-4.18) were positively associated with the males' SI. However, having emptiness inside (OR = 4.39, 95% CI: 2.19-8.79), quarreling with parents (OR = 3.72, 95% CI: 2.16-6.41), insomnia (OR = 3.28, 95% CI: 1.85-5.80), feeling anxious (OR = 2.62, 95% CI: 1.46-4.70), and longing for father's emotional warmth (OR = 0.38, 0.20-0.72) were associated mostly with females' SI. Conclusions: Female adolescents, who felt emptiness from their families and their fathers' emotional warmth, were at much higher risk of having SI during COVID-19 lockdown. We must specify a suicide prevention policy and interventions for adolescents in the pandemic crisis based on gender gaps.

COVID-19 Pandemic Lockdown: An Excellent Opportunity to Study the Effects of Trawling Disturbance on Macrobenthic Fauna in the Shallow Waters of the Gulf of Gabès (Tunisia, Central Mediterranean Sea).

This study describes for the first time in the central Mediterranean Sea the effects of bottom trawling on macrobenthic fauna in tidal channels of the Kneiss Islands in the Gulf of Gabès, Tunisia. Following a BACI protocol, two control stations (protected by artificial reefs) and two trawled stations (impacted stations) were sampled during a period with the absence of bottom trawling activity (the COVID-19 pandemic lockdown period from March to May 2020) and during a trawled period. Although bottom trawling had no impact on sediment composition, this anthropogenic activity reduced the concentration of dissolved oxygen and had a noticeable effect on water column turbidity. The absence of trawling led to a significant increase in biomass, number of species, and abundance of total macrofauna. This illustrated the negative effect of trawling activity in shallow waters and the high resilience of macrobenthic communities of the tidal ecosystem of the Kneiss Islands. In the future, it would be very important to control the use of this destructive fishing gear due to its negative impact on the marine habitat and macrofauna, which represents essential prey for fishes and birds living in this protected area.

Facing the pandemic lockdown questionnaire - FPLQ: A brief tool to assess individual differences in front of pandemic experience.

This paper presents the development and the initial validation of a self-report questionnaire (the Facing the Pandemic Lockdown Questionnaire - FPLQ) focused on the way in which people faced the impact of the lockdown related to the Coronavirus Disease 19. 504 adults (81.55% females; M age = 32.71 years, SD = 11.19) took part to the study. Exploratory and confirmatory factor analyses revealed a 15-item 4-factor structure, invariant for gender and age: two dimensions related to maladaptive processes (i.e., "Perception of low social connectedness and lack of routines" and "Health worry") and two dimensions related to adaptive processes (i.e., "Positive re-thinking" and "Perception of online social connectedness"). Further, we investigated the associations between these dimensions and measures pertaining cognitive (i.e., internal and external health locus of control), emotional (i.e., positive and negative affect), and relational (i.e., attitude and behaviors toward civic engagement) processes, also testing the moderating role of gender and age. Finally, the potential usefulness of this new tool for both extant and future psychological research was highlighted.

Meteorological influence on forecasting urban pollutants: Long-term predictability versus extreme events in a spatially heterogeneous urban ecosystem.

With the escalation of heat- and pollution-related threats in cities across the globe, timely counteractions and emergency procedures are vital, which calls for accurate co-prediction of urban heat and air quality under both standard conditions and under extreme events. In this study, we used historical hourly data recorded at 9 sites across the Sydney metropolitan area to test the performance of long short-term memory (LSTM) forecasting architectures in predicting 5 urban pollutants based on different combinations of meteorological inputs and considering standard, bushfire, and pandemic lockdown conditions. We demonstrate that, in most cases and even in a fast-growing city, there is no significant benefit achieved by including extra predictors to temperature and humidity, when adequate forecasting techniques capable of learning long-term dependencies are used. Further, in agreement with previous studies, we provide evidence of ozone's higher responsiveness to all weather parameters and thus enhanced predictability and PM10's lower predictability as compared to all other considered urban pollutants. The prediction accuracy tends to be comparable between standard conditions and bushfire events. However, the predictability significantly declines under anomalies in anthropogenic patterns and urban metabolic rates as those recorded during the pandemic. The inclusion of local emission sources and anthropogenic factors in the input dataset is considered necessary for NO and PM10 to properly predict urban air quality, especially under human-related extreme conditions.

The Wisdom Acquired During Emergencies Scale - Development and Validity.

The COVID-19 pandemic and its related lockdown restrictions had repercussions on health status, psychological states of mind, and emotion regulation. Attitudes towards these restrictions, beliefs, emotions and behaviours could be wise, as in the acceptance of, and adaptation to, these constraints. On the other hand, they could be unwise, as in the rejection of rules and limitations, denial of the consequences, irrational beliefs, self-accusation, rage and general intolerance. This study aims to introduce the development and validation of the 25-item Wisdom Acquired During Emergencies Scale (WADES). It is a measure to assess the wisdom and self-regulation that are needed to cope with unexpected and unpredictable emergency situations. On the basis of a preliminary study (N1 =212 Italian adults), a multiple-choice scale of 52 items was developed. In the reliability study (N2 =1777), items were scaled, analysed according to the optimal score technique and selected to provide a final and reliable version (Cronbach's α=0.83). The validity study (N3 =1,345, N4 =1,445, N5 = 878) provided correlations with established scales measuring, for example, traditional wisdom, emotion regulation, empathy, post-traumatic growth, collectivism, conscientiousness and satisfaction with life. The results confirmed that high scores on the WADES are associated with the ability to regulate emotions, control impulses and develop goals in emotional situations, to tolerate current difficulties, while developing new attitudes, values and behaviours, entailing changes in self-perception and relationships. It was thus confirmed that high WADES scores indicate a higher degree of acquired wisdom.

Global assessment of tropospheric and ground air pollutants and its correlation with COVID-19.

The declaration of COVID-19 pandemic by the WHO initiated a series of lockdowns globally that varied in stringency and duration; however, the spatiotemporal effects of these lockdowns on air quality remain understudied. This study evaluates the global impact of lockdowns on air pollutants using tropospheric and ground-level indicators over a five-month period. Moreover, the relationship between air pollution and COVID-19 cases and mortalities was examined. Changes in the global tropospheric (NO2, aerosols, and O3) and ground-level (PM2.5, PM10, NO2, and O3) pollutants were observed, and the maximum air quality improvement was observed immediately after lockdown. Except for a few countries, a decline in air pollutants correlated with a reduction in Land Surface Temperature (LST). Notably, regions with higher tropospheric NO2 and aerosol concentrations were also COVID-19 hotspots. Our analysis showed moderate positive correlation for NO2 with COVID-19 cases (R2 = 0.33; r = 0.57, P = 0.006) and mortalities (R2 = 0.40; r = 0.63, P = 0.015), while O3 showed a weak-moderate positive correlation with COVID-19 cases (R2 = 0.22; r = 0.47, P = 0.003) and mortalities (R2 = 0.12; r = 0.35, P = 0.012). However, PM2.5, and PM10 showed no significant correlation with either COVID-19 cases or mortality. This study reveals that humans living under adverse air pollution conditions are at higher risk of COVID-19 infection and mortality.
