The education sector experienced substantial impacts during the COVID-19 pandemic resulting from worldwide restrictions.
To examine differences in the sleep patterns, sexual activity, screen use, and food intake of students and non-students during the COVID-19 pandemic.
This was a global cross-sectional study conducted in the second half of 2020 using multiple social media platforms to recruit study participants globally. A close-ended questionnaire was administered anonymously in English, French, Spanish, Portuguese, and Arabic to adults ages 18 and older. The outcome variables considered in analyses were changes in sleep pattern, sexual activity, screen use, and food intake. The explanatory variable was student status categorized as students vs. non-student. T-test, chi-square, and Mann Whitney U tests were used to assess differences between student and non-student populations. One logistic regression model was built for each outcome variable. Country of residence and country income level were included in the adjusted models.
There were 17,008 participants of which 3,793 (22.3%) were students. Of the total sample, 4,889 (28.7%) reported changes in sleep, 4,642 (31.8%) reported increases in sexual activity, 10,278 (70.7%) reported increases in screen use, and 5,662 (40.2%) reported increases in food intake during the pandemic. Compared to non-students, students had significantly higher odds of reporting changes in sleep (AOR = 1.52), increases in sexual activity (AOR = 1.79), and increases in screen use (AOR = 1.36) but lower odds of reporting increase in food intake (AOR = 0.87).
Students displayed higher risk of experiencing changes in sleep, sexual behavior, and screen use during the COVID-19 pandemic. This has the potential to lead to broader adverse effects on students' overall wellbeing. The findings and implications raise further obligations on the education sector to put extra-curricular support systems in place that address COVID-19 related behavior changes that have the potential to adversely impact students' wellbeing.

Background
COVID-19 lockdown resulted in the closure of schools with associated problems. The aim of this study was to determine the associations between depression, fear of contracting COVID-19 infection and the use of self-care measures by college students during the first wave of the COVID-19 pandemic.
Methods
This was a cross-sectional study that collected data from undergraduate and postgraduate college students 18 years and older from 152 countries between June and December 2020. Study participants were recruited through crowdsourcing using various social media platforms including Facebook, Twitter, and Instagram, WhatsApp groups and emails to participants in the collaborators’ networks. The dependent variables were fear of contracting COVID-19 and depression while the independent variable was students’ self-care measures. Multivariable logistic regression models were conducted to assess the associations between the dependent and independent variables.
Results
Of the 2840 respondents, 1305 (46.0%) had fears of contracting COVID-19 and 599 (21.1%) reported depression. The most common self-care measures were phone calls with friends/family (60.1%) and video chat (52.8%). Learning a new skill was significantly associated with higher odds of fear of contracting COVID-19 (AOR = 1.669) and lower odds of having depression (AOR = 0.684). Talking to friends/family through video chat (AOR = 0.809) was significantly associated with lower odds of feeling depressed while spending time with pets (AOR = 1.470) and taking breaks from the news/social media (AOR = 1.242) were significantly associated with higher odds of feeling depressed. Students from lower middle-income countries (AOR = 0.330) had significantly lower odds of feeling depressed than students from low-income countries.
Conclusion
Self-care strategies involving social interactions were associated with less depression. Coping strategies with more cognitive demands may significantly reduce the risk of fear of COVID-19. Special attention needs to be given to students in low-income countries who have higher odds of depression during the pandemic than students from other countries.

To investigate factors associated with healthcare utilization by adults in the Kingdom of Saudi Arabia (KSA) during the COVID-19 pandemic. Based on Andersen’s Behavioral Model of Health Services utilization, we conducted logistic regressions to determine the relationship between predisposing factors (age, gender, education, employment status), need factors (critical medical needs), and enabling factors (insurance coverage, financial loss) on healthcare utilization (challenges accessing medical health care needs, resorting to alternative care, unable to attend medical appointments) as the main outcome. Data of 958 adults residing in KSA were extracted. Financial loss increased the odds of challenges in accessing healthcare (OR: 1.73) and lowered the odds of resorting to alternative medical care (OR: 0.63) and inability to attend healthcare appointments (OR: 0.55). Public insurance increased the odds of skipping healthcare appointments (OR: 1.62). Need factors were associated with lower odds of facing challenges accessing healthcare (OR: 0.37), higher odds of resorting to alternative medical care (OR: 5.65), and failure to attend healthcare appointments (OR: 1.92) respectively. Factors known to enable healthcare utilization should be continuously evaluated during emergency situations. Alternative routes of health provision, along with proper health education, should be accessible to all socioeconomic groups.
Plain language summary
Purpose: This study investigated factors associated with healthcare utilization by adults in Saudi Arabia during the COVID-19 pandemic. Methods: An online self-administered questionnaire was distributed during the first wave of COVID-19 outbreak to adults aged 18 years and above residing in Saudi Arabia. The questionnaire gathered data about healthcare utilization (challenges accessing medical health care needs, resorting to alternative care, unable to attend medical appointments) participants’ demographics (age, gender, education, employment status), critical medical needs and enabling factors (insurance coverage, financial loss). Conclusions: From the 958 adults residing in Saudi Arabia, we found that those with financial loss had challenges accessing healthcare and were less likely to resort to alternate medical care. While those with public insurance were more likely to skip healthcare appointments. Those with medical needs were less likely to face challenges accessing healthcare but were more likely to resort to alternative medical care and more likely to skip healthcare appointments. Implications: The study highlights factors known to enable healthcare utilization that should be continuously evaluated during emergency situations. The study also highlights the need for alternative routes of health provision, along with proper health education. The results of the study may help policy makers during outbreaks to prioritize disadvantaged populations and those with medical needs. Limitations: This was self-reported data which may be subjected to recall bias. We did not assess factors such health-seeking behaviors of participants before COVID-19 as well as participants’ nationality. Expatriates working in the private sector are deprived of the free public healthcare services and financial support available to Saudi nationals, which could have altered the current findings.

This study assessed the association between sociodemographic factors and post-traumatic stress symptoms (PTSS) among 18–24-year-olds during the first wave of the COVID-19 pandemic. This was a secondary analysis of data from 4508 individuals collected through an online survey conducted between June and January 2021. PTSS was measured as a dependent variable using the checklist for post-traumatic stress disorder in civilians. Age, birth sex, sexual, level of education, access to emotional and social support, and emotional distress were the independent variables. A multivariate logistic regression analysis was conducted to determine the associations between the dependent and independent variables while controlling for the country related confounding variables. Females (AOR:2.023), sexual minority individuals (AOR:1.868), those who did not disclose their sexual identify (AOR:1.476), those with poor access to emotional and social support (AOR:4.699) and individuals with no formal education (AOR:13.908), and only primary level education (AOR:4.521) had higher odds of PTSS. The study highlights the multifaceted nature of PTSS during the pandemic and suggests the importance of promoting access of young people, especially females, sexual minority individuals and those with low educational status, to emotional/social support to mitigate the probability of PTSS, especially among sexual minority individuals.

Background
Health behaviours are influenced by individual characteristics including age, gender, education and economic level. This study aimed to assess the associations between individual-level determinants and adherence to COVID-19 preventive measures.
Methods
We performed secondary analyses of international data collected using an online survey during the first wave of the COVID-19 pandemic between June and December 2020. The dependent variables were self-reported adherence to COVID-19 preventive measures (wearing of face masks, frequent washing/sanitizing of hands, physical distancing, working remotely). The independent variables were age, sex at birth (female vs male), having a chronic disease related elevated risk for severe COVID-19 (none/little, might be at increased risk, at increased risk), educational level completed (no formal education, primary, secondary vs college/university) and employment status (retiree, students, not employed vs employed). Four multivariate logistic regression analyses were conducted to determine the associations between the dependent variables and independent variables. Interaction terms with country-income level were tested in regressions to explore its moderating effect.
Results
Out of 16,866 respondents, 12,634 (74.9%) wore masks or face coverings, 12,336 (73.1%) washed or sanitized their hands frequently, 11,464 (68.0%) reported adherence to physical distancing and 5,646 (33.5%) worked remotely. In adjusted analyses, increased age, college/university education, employment, and having risks for severe COVID-19 were associated with significantly higher odds of adhering to COVID-19 preventive measures. Retirees and students had lower odds of adhering to COVID-19 prevention measures than employed individuals. Males had significantly lower odds of wearing face masks (AOR: 0.901), frequent washing/sanitizing hands (AOR: 0.774) and working remotely (AOR: 0.875) compared to females. Country-income level generally moderated the above relationships such that the associations disappeared in lower income countries.
Conclusion
The study findings suggest that the individual socio-demographic factors—age, sex, employment status, education status and having a chronic disease – influence adherence to COVID-19 preventive measures. Findings further reiterate the need for health education and health promotion campaigns on preventive health measures to focus on subpopulations, such as younger males, students and retirees, that require targeted or unique messaging.

Differences in COVID-19 Preventive Behavior and Food Insecurity by HIV Status in Nigeria
2022
The aim of the study was to assess if there were significant differences in the adoption of COVID-19 risk preventive behaviors and experience of food insecurity by people living with and without HIV in Nigeria. This was a cross-sectional study that recruited a convenience sample of 4471 (20.5% HIV positive) adults in Nigeria. Binary logistic regression analysis was conducted to test the associations between the explanatory variable (HIV positive and non-positive status) and the outcome variables—COVID-19 related behavior changes (physical distancing, isolation/quarantine, working remotely) and food insecurity (hungry but did not eat, cut the size of meals/skip meals) controlling for age, sex at birth, COVID-19 status, and medical status of respondents. Significantly fewer people living with HIV (PLWH) reported a positive COVID-19 test result; and had lower odds of practicing COVID-19 risk preventive behaviors. In comparison with those living without HIV, PLWH had higher odds of cutting meal sizes as a food security measure (AOR: 3.18; 95% CI 2.60–3.88) and lower odds of being hungry and not eating (AOR: 0.24; 95% CI 0.20–0.30). In conclusion, associations between HIV status, COVID-19 preventive behaviors and food security are highly complex and warrant further in-depth to unravel the incongruities identified.

An online survey was conducted to identify factors associated with financial insecurity, food insecurity and poor quality of daily lives of adults in Nigeria during the first wave of the COVID-19 pandemic. The associations between the outcome (experience of financial loss, changes in food intake and impact of the pandemic on daily lives) and the explanatory (age, sex, education level, anxiety, depression, HIV status) variables were determined using logistic regression analysis. Of the 4439 respondents, 2487 (56.0%) were financially insecure, 907 (20.4%) decreased food intake and 4029 (90.8%) had their daily life negatively impacted. Males (AOR:0.84), people who felt depressed (AOR:0.62) and people living with HIV -PLHIV- (AOR:0.70) had significantly lower odds of financial insecurity. Older respondents (AOR:1.01) had significantly higher odds of financial insecurity. Those depressed (AOR:0.62) and PLHIV (AOR:0.55) had significantly lower odds of reporting decreased food intake. Respondents who felt anxious (AOR:0.07), depressed (AOR: 0.48) and who were PLHIV (AOR:0.68) had significantly lower odds of reporting a negative impact of the pandemic on their daily lives. We concluded the study findings may reflect a complex relationship between financial insecurity, food insecurity, poor quality of life, mental health, and socioeconomic status of adults living in Nigeria during the COVID-19 pandemic.

ABSTRACT Tannase has significant importance due to its various industrial applications. Tannase production using pure tannic acid as substrate is very expensive especially at industrial level. In present study, various physical parameters and medium components were optimized for maximum tannase production employing Raoultella ornithinolytica in solid state fermentation (SSF) using corn (Zea mays) leaves as substrate to reduce its production cost. The maximum tannase production was obtained with 60% initial substrate moisture contents, tap water as enzyme extraction medium with 2 mL volume, 45°C incubation temperature, pH 7, 300 µL inoculum size, 24 h incubation period in agitated condition with substrate particle size of 4mm during one factor at a time optimization. Concentrations of medium components (3.75% tannic acid, 0.75% K HPO and 1.25% yeast extract) were optimized with central composite design of response surface methodology. Tannase characterization data revealed that 5.0 pH, 30°C temperature, 60 minutes incubation and 0.45% of substrate concentration showed highest tannase activity. The results depict utilization potential of low cost substrate (corn leaves) to reduce the production cost of tannase.

Background
The COVID-19 pandemic had socioeconomic effects in Africa. This study assessed the social and economic determinants of healthcare utilization during the first wave of COVID-19 among adults in Ghana.
Methods
Information about individuals residing in Ghana was derived from a survey conducted across multiple countries, aiming to evaluate the impact of the COVID-19 pandemic on the mental health and overall well-being of adults aged 18 and above. The dependent variable for the study was healthcare utilization (categorized as low or high). The independent variables were economic (such as financial loss, job loss, diminished wages, investment/retirement setbacks, and non-refunded travel cancellations) and social (including food scarcity, loss of financial support sources, housing instability, challenges affording food, clothing, shelter, electricity, utilities, and increased caregiving responsibilities for partners) determinants of health. A multinomial logistic regression was conducted to identify factors associated with healthcare utilization after adjusting for confounders (age, gender, access to medical insurance, COVID-19 status, educational background, employment, and marital status of the participants).
Results
The analysis included 364 responses. Individuals who encountered a loss of financial support (AOR: 9.58; 95% CI: 3.44–26.73;
p
< 0.001), a decrease or loss of wages (AOR: 7.44, 95% CI: 3.05–18.16,
p
< 0.001), experienced investment or retirement setbacks (AOR: 10.69, 95% CI: 2.60-43.88,
p
= 0.001), and expressed concerns about potential food shortages (AOR: 6.85, 95% CI: 2.49–18.84,
p
< 0.001) exhibited significantly higher odds of low healthcare utilization during the initial phase of the pandemic. Contrastingly, participants facing challenges in paying for basic needs demonstrated lower odds of low healthcare utilization compared to those who found it easy to cover basic expenses (AOR: 0.19, 95% CI: 0.06–0.67,
p
= 0.001).
Conclusion
Economic and social factors were associated with low healthcare utilization in Ghana during the first wave of the pandemic. Investment or retirement loss and financial support loss during the pandemic had the largest effect on healthcare utilization. Further research is needed to understand the connection between concerns about food shortages, welfare losses during pandemics and healthcare utilization during pandemics in Ghana.

Background
Nigeria is a country with high risk for traumatic incidences, now aggravated by the COVID-19 pandemic. This study aimed to identify differences in COVID-19 related post-traumatic stress symptoms (PTSS) among people living and not living with HIV; to assess whether PTSS were associated with COVID-19 pandemic-related anger, loneliness, social isolation, and social support; and to determine the association between PTSS and use of COVID-19 prevention strategies.
Methods
The data of the 3761 respondents for this analysis was extracted from a cross-sectional online survey that collected information about mental health and wellness from a convenience sample of adults, 18 years and above, in Nigeria from July to December 2020. Information was collected on the study’s dependent variable (PTSS), independent variables (self-reported COVID-19, HIV status, use of COVID-19 prevention strategies, perception of social isolation, access to emotional support, feelings of anger and loneliness), and potential confounder (age, sex at birth, employment status). A binary logistic regression model tested the associations between independent and dependent variables.
Results
Nearly half (47.5%) of the respondents had PTSS. People who had symptoms but were not tested (AOR = 2.20), felt socially isolated (AOR = 1.16), angry (AOR = 2.64), or lonely (AOR = 2.19) had significantly greater odds of reporting PTSS (
p
< 0.001). People living with HIV (AOR = 0.39), those who wore masks (AOR = 0.62) and those who had emotional support (AOR = 0.63), had lower odds of reporting PTSS (
p
< .05).
Conclusion
The present study identified some multifaceted relationships between post-traumatic stress, HIV status, facemask use, anger, loneliness, social isolation, and access to emotional support during this protracted COVID-19 pandemic. These findings have implications for the future health of those affected, particularly for individuals living in Nigeria. Public health education should be incorporated in programs targeting prevention and prompt diagnosis and treatment for post-traumatic stress disorder at the community level.
