Physical Fitness and Body Mass Index Status of Hong Kong Primary Schoolchildren across the COVID-19 Pandemic, before and after School Closure.

OBJECTIVE: To determine whether health-related physical fitness and body mass index (BMI) status differed before and after school closure from the COVID-19 pandemic in a population-based cohort of Hong Kong primary schoolchildren. STUDY DESIGN: We examined the BMI z score, BMI status, and physical fitness z scores including (i) upper limb muscle strength, (ii) 1-minute sit-up test, (iii) sit-and-reach test, and (iv) endurance run tests, among 3 epochs: prepandemic (September 2018-August 2019), before school closure (September 2019-January 2020), and partial school reopening (September 2021-August 2022), using a repeated cross-sectional approach. RESULTS: A total of 137 752 primary schoolchildren aged 6-12 years were recruited over 3 academic years. Obesity increased significantly from 25.9% in 2018/19 to 31.0% in 2021/22, while underweight increased slightly from 6.1% to 6.5%. All tested parameters were adversely affected by the pandemic. The negative trend over time was far more pronounced in all 4 physical fitness scores in the underweight group, although performance in handgrip strength had no significance between 2018/19 and 2021/22. CONCLUSIONS: Schoolchildren who are both underweight and overweight/obese are vulnerable to adverse changes in physical fitness during the COVID-19 pandemic. To eliminate the negative health and fitness outcomes, it is urgent to develop strategies for assisting schoolchildren in achieving a healthy weight, especially in the postpandemic era.

Long-term surveillance of SARS-CoV-2 in the school community from Campo Grande, Brazil.

BACKGROUND: The COVID-19 pandemic has significantly impacted education systems worldwide, with Brazil being one of the countries with the longest school closures. Over a million children and teenagers have been affected, leading to increased hunger and nutritional deficiencies. This study aimed to implement long-term surveillance of SARS-CoV-2 infections in public and private schools in Campo Grande, Brazil, after returning to in-person classes. METHODS: The study involved testing and genomic surveillance at 23 public and private schools in Campo Grande, Mato Grosso do Sul, Brazil, from October 18, 2021 to November 21, 2022. The participants eligible for enrollment were students aged 6-17 years and staff members from school institutions. At the time of collection, participants were asked if they had symptoms in the last two weeks. Whole-genome sequencing of SARS-CoV-2 was conducted to identify circulating variants and to compare them with those detected in the municipality. The demographic data and clinical history of the participants were described, and a logistic regression model was used to understand how the RT-qPCR results could be related to different characteristics. RESULTS: The study included 999 participants, most of whom were women. A total of 85 tests were positive, with an overall positivity rate of 3.2%. The dynamics of case frequency were consistent with those observed in the municipality during the study period. The most common symptoms reported were cough, rhinorrhea, headache, and sore throat. Symptoms were significantly associated with SARS-CoV-2 infection. Eleven lineages were identified in school community samples, with a frequency of occurrence per period similar to that found in the sequences available for the municipality. The most prevalent lineages within the sampling period were BA.2 (59.3%) and BA.5 (29.6%). CONCLUSIONS: Our findings demonstrate that schools can play a crucial role in epidemiological surveillance, helping trigger rapid responses to pathogens such as SARS-CoV-2. Long-term surveillance can be used to track outbreaks and assess the role of children and adults in transmission. It can also contribute to pandemic preparedness, enabling a rapid response to emergencies, such as COVID-19.

Developmental Losses of Preschool Children Three Years into the COVID-19 Pandemic.

The COVID-19 pandemic and resulting mitigation measures have led to increased vulnerabilities in early child development. However, research is scarce and there are no studies on the persistence of these losses three years into the pandemic among young children. To fill in this gap, we examined census-like evaluations of school readiness carried out among preschoolers in Uruguay. The assessments were carried out among 5 cohorts of 5-year-olds: who were assessed prior to the pandemic (2018, 2019); during the pandemic (2020, 2021); and after the health emergency declaration ended in Uruguay (2022). A total of 180,984 teacher evaluations were included covering cognitive, motor and socio-emotional development, as well as attitudes toward learning. Overall, we found that scores in most spheres of child development decreased from before to during the pandemic in 2020 and 2021. In 2022, scores returned to pre-pandemic levels. Our findings suggest the recovery of developmental losses among cohorts of children in kindergarten took more than two years in a country that experienced a mild-to-moderate impact of the COVID-19 pandemic.

Accountability Battle: A Critical Analysis of a Charter Renewal Decision.

Charter school policy represents two simultaneous forms of accountability, in which schools are accountable to both parents and authorizers. This study of a K-8 charter renewal decision interrogates these accountability relationships and the role of race and power in privileging the interests of particular stakeholders over others. Using counternarrative methodology and qualitative interviews and observations, we draw on critical race theory and new managerialism to make sense of the competing accounts surrounding a non-renewal process. We find four areas of tension, in which district officials subscribe to new managerialist authorizing styles that leave little room for participation from the Black and low-income school community. We conclude with recommendations for how districts can partner with communities to work toward frameworks of accountability that value the goals of multiple stakeholder groups.

School and class closures and adolescent mental health during the second and later waves of the COVID-19 pandemic in Finland: a repeated cross-sectional study.

BACKGROUND: Since the start of the COVID-19 pandemic, several studies have shown deterioration of adolescents' mental health when comparing periods before and after the start of the pandemic when there were national school closures. Less is known of the following waves with more variation in school closures and their duration. We study here, if variation in school or class closures was related to adolescents' mental health, if the duration mattered, and if the relationships were gender sensitive. METHODS: All comprehensive schools in Finland were invited to participate. Students (grades 7-9, age 13-16 years) answered digitally in November-December 2020 (n = 41,041) and April-May 2021 (n = 28,501). The responses were given anonymously. Mental health was measured by daily health complaints and moderate/severe anxiety (GAD-7, only in 2021). School and class closures were combined to a variable (yes/no). The duration of a closure was analysed in weeks. Logistic regression analysis was used. RESULTS: In 2020, 14% of pupils reported a school closure and 33% in 2021. The gender-adjusted odds for daily health complaints were higher among those with the school or class closure compared to those without (OR = 1.2 (1.1-1.3) in 2020; OR = 1.3 (1.2-1.3) in 2021). For anxiety, the corresponding OR was 1.3 (1.2-1.4). Girls had higher odds for both measures than boys and the non-binary gender had the highest. A one-week increase in the duration of closure had a small effect on daily health complaints OR = 1.05 (1.02-1.09) in 2020; OR = 1.05 (1.02-1.08) in 2021) and anxiety OR = 1.05 (1.01-1.08). Gender differences in the associations of the school or class closure with mental health were negligible. CONCLUSIONS: A specific negative influence of school or class closures on adolescents' mental health was seen when comparing those who had school/class closure and those who did not during the further waves of the pandemic. The duration of closure had a small effect, too. The non-binary gender had lowest mental health, but the influence of school closure on mental health was mainly similar between the genders. School closures are one of the factors in adolescents' mental health, but not the only one.

Seeing the pandemic through children's eyes: Exploring Turkish children's views on COVID-19 pandemic by focus-group discussions.

BACKGROUND: The direct and indirect effects of the COVID-19 pandemic on children and youth people are well documented. Little is known about children's experiences of the pandemic in their own words. We aimed to explore Turkish children's experiences and views about the pandemic, across private and public educational systems. METHODS: Six focus group discussions were conducted online with 30 children aged between 7 to 18 years in 2021. Children were enrolled through snowball sampling technique according to developmental age groups. A thematic analysis was conducted. RESULTS: We identified five themes: Compliance with public health measures about preventing the spread of COVID-19, changes in daily routines, emotional responses to the pandemic, distance education, and adaptive responses. Overall, children were well informed and receptive to the public health preventive measures with the exception of older children's tendency to disregard physical distancing with friends. They reported frustration with those who did not comply with measures and believed that the authorities should strictly enforce public health requirements. Emotional responses comprised fear of family members and themselves being infected, anxiety produced by the uncertainty of the virus, and the loss of social support. There was a perceived disparity between students from public and private schools regarding academic self-competence. Positive aspects of the pandemic included positive interactions with family members and the acquisition of new hobbies. Although most children acknowledged the support of their parents to deal with challenges, children of health workers were particularly isolated in terms of emotional support. CONCLUSION: Our findings offer additional insights and validate previous research on the negative and positive effects of COVID-19 from the child's perspective across private and public educational systems. This study contributes to global advocacy efforts aimed at understanding the impact of the pandemic on children.

The impact of the COVID-19 pandemic on children's learning and wellbeing: Evidence from India.

We study the impact of the COVID-19 pandemic and associated school closure on primary school children's learning and mental wellbeing in Assam, India. Using a comprehensive dataset that tracked and repeatedly surveyed approximately 5000 children across 200 schools between 2018 and 2022, we find that children lost the equivalent of nine months of learning in mathematics and eleven months in language, during the pandemic. Children lacking resources and parental support experienced the largest losses. Regular practice, teacher interaction, and technology were associated with less learning loss. Over the same period, children's psychological wellbeing improved. Our research provides valuable insights for designing post-emergency programs.

On return to school: disorder symptoms, stress at home and evaluations of school COVID-19 measures.

Background: Social restrictions during the COVID-19 pandemic had a major impact on the mental health of children. Yet, analyses on the mental health of younger children in the later course of the pandemic are scarce. The present study assessed 8- to 11-year-olds' internalising disorder symptoms during the last three weeks, from the third week of February through to the first week of March, of the 2021 national lockdown.Method: One hundred and forty-five pupils, including a subset of keyworkers' children who had face-toface schooling, completed the validated Revised Child Anxiety and Depression scales, items on COVID-related stress at home, and evaluations of home-learning and school's measures for reopening.Results: Symptoms increased with age in months and/or number of siblings. Girls reported more symptoms and home stress than boys did. Pupils who had face-to-face schooling were more satisfied with school measures and less satisfied with home learning compared with those who only had home learning. Hierarchical regression analyses corroborated the contributions of sociodemographic characteristics and found that home stress and school measures evaluations were associated most with major depression, generalised anxiety, and social phobia.Conclusion: Findings can contribute to mental health practice by promoting school communications and family and educator awareness of stressors, vulnerabilities and symptoms to boost pupils' readiness for school returns.

A global assessment of the impact of school closure in reducing COVID-19 spread.

Prolonged school closure has been adopted worldwide to control COVID-19. Indeed, UN Educational, Scientific and Cultural Organization figures show that two-thirds of an academic year was lost on average worldwide due to COVID-19 school closures. Such pre-emptive implementation was predicated on the premise that school children are a core group for COVID-19 transmission. Using surveillance data from the Chinese cities of Shenzhen and Anqing together, we inferred that compared with the elderly aged 60 and over, children aged 18 and under and adults aged 19-59 were 75% and 32% less susceptible to infection, respectively. Using transmission models parametrized with synthetic contact matrices for 177 jurisdictions around the world, we showed that the lower susceptibility of school children substantially limited the effectiveness of school closure in reducing COVID-19 transmissibility. Our results, together with recent findings that clinical severity of COVID-19 in children is lower, suggest that school closure may not be ideal as a sustained, primary intervention for controlling COVID-19. This article is part of the theme issue 'Data science approach to infectious disease surveillance'.

Delays, Masks, the Elderly, and Schools: First Covid-19 Wave in the Czech Republic.

Running across the globe for nearly 2 years, the Covid-19 pandemic keeps demonstrating its strength. Despite a lot of understanding, uncertainty regarding the efficiency of interventions still persists. We developed an age-structured epidemic model parameterized with epidemiological and sociological data for the first Covid-19 wave in the Czech Republic and found that (1) starting the spring 2020 lockdown 4 days earlier might prevent half of the confirmed cases by the end of lockdown period, (2) personal protective measures such as face masks appear more effective than just a realized reduction in social contacts, (3) the strategy of sheltering just the elderly is not at all effective, and (4) leaving schools open is a risky strategy. Despite vaccination programs, evidence-based choice and timing of non-pharmaceutical interventions remains an effective weapon against the Covid-19 pandemic.

Diffusion of COVID-19 among children and adolescents during the second and third waves of the pandemic in Italy.

This paper explores COVID-19 diffusion among children and adolescents (up to 19 years old) in Italy using the publicly available data that were collected and released by the Italian National Institute of Health (ISS). We consider in more detail the so-called second and third waves of the pandemic in Italy and explore the relationship between schools opening and the diffusion of COVID-19, which is a highly debated topic in the recent reference literature. We analyse the dynamics of COVID-19 incidence in the country as a whole and in its individual regions. Moreover, we compare the regions in which different levels of restrictions were imposed during the pandemic as well as different school closure calendars. We found there to be a significant correlation between the dynamics of the COVID-19 infections among young people in Italy and school closures during both the second and the third waves of the pandemic. CONCLUSION: Specifically, we found school closures to have mitigated the spread of the infection, especially among patients between the ages of 14 and 19. WHAT IS KNOWN: • The relationship between the opening of schools and the diffusion of COVID-19 is a debated topic. • SARS-CoV-2 diffusion among school-aged adolescents is almost twice as that among children. • SARS-CoV-2 is a mild disease for infants and children. WHAT IS NEW: • We analysed original data on the diffusion of COVID-19 among children and adolescents in Italy. • We calculated incidence of COVID-19 with reference to school-age classes and compared over time in the whole country and in the regions of Italy. • We analysed incidence dynamics considering school closures and other restrictions imposed by the local and national authorities to limit virus diffusion.

Temporal patterns of sleep and eating among children during school closure in Japan due to COVID-19 pandemic: associations with lifestyle behaviours and dietary intake.

OBJECTIVE: To identify temporal patterns of sleep and eating among school-age children during school closure due to the COVID-19 pandemic and to examine their associations with lifestyle behaviours and dietary intake. DESIGN: In this cross-sectional study, questionnaires were used to assess sleep and eating times, lifestyle behaviours and dietary intake during school closure. Latent class analysis was performed to identify temporal patterns of sleep and eating based on self-reported clock times for wake-up, going to bed and eating meals. Lifestyle behaviours and dietary intake were compared between latent classes. SETTING: Forty-eight primary and secondary schools in Japan. PARTICIPANTS: Totally, 6220 children (aged 8-15 years). RESULTS: Four patterns, labelled 'Very early (20 % of children)', 'Early (24 %)', 'Late (30 %)' and 'Very late (26 %),' were identified and ordered according to the circadian timing. Latter patterns were characterised by later timings of sleep and eating, especially in clock times for wake-up, breakfast and lunch compared with earlier patterns. Children with latter patterns had a less physically active lifestyle, longer screen time (≥4 h/d), shorter study time (<2 h/d) and more frequent skipping of breakfast and lunch than those with earlier patterns. In addition, children with latter patterns had lower intakes of several vitamins, vegetables, fruits, fish and shellfish and dairy products and higher intakes of sugar and confectionaries and sweetened beverages. CONCLUSION: More than half of the participants had later wake-up, breakfast and lunch during school closure, which was associated with more unfavourable lifestyles and dietary intakes.

Relationship between screen time among children and lower economic status during elementary school closures due to the coronavirus disease 2019 pandemic.

BACKGROUND: This study aimed to examine whether the extended use of a variety of digital screen devices was associated with lower economic status and other environmental factors among Korean elementary school children and their caregivers during school closures precipitated by the coronavirus disease 2019 (COVID-19) pandemic. METHODS: A total of 217 caregivers of children 7-12 years of age from Suwon, Korea, were recruited and asked to respond to a self-administered questionnaire in June 2020. The questionnaire addressed demographic information and children's use of digital media, in addition to their caregivers. The t-test was used for continuous variables, and the Kruskal-Wallis test was used for variables measured on an interval scale. A multiple regression analyses were performed to examine the effects of significant correlative factors on screen time in children as predictors. RESULTS: Children with lower household incomes demonstrated a higher frequency and longer duration of smartphone and tablet personal computer use compared to those from higher income households. Children of households in which incomes decreased after COVID-19 used smartphones and tablet PCs more often and for longer durations. Children from households that experienced decreased income(s) after COVID-19 used personal computers more often and for a longer duration, and children from low-income families engaged in longer screen time on smartphones. A change in primary caregiver(s) may have increased children's screen time on smartphones. CONCLUSION: Lower household income was associated with longer screen time among children, and poor mental health among caregivers during school closures precipitated the COVID-19 pandemic.

A database of US state policies to mitigate COVID-19 and its economic consequences.

BACKGROUND: Since COVID-19 first appeared in the United States (US) in January 2020, US states have pursued a wide range of policies to mitigate the spread of the virus and its economic ramifications. Without unified federal guidance, states have been the front lines of the policy response. MAIN TEXT: We created the COVID-19 US State Policy (CUSP) database ( https://statepolicies.com/ ) to document the dates and components of economic relief and public health measures issued at the state level in response to the COVID-19 pandemic. Documented interventions included school and business closures, face mask mandates, directives on vaccine eligibility, eviction moratoria, and expanded unemployment insurance benefits. By providing continually updated information, CUSP was designed to inform rapid-response, policy-relevant research in the context of the COVID-19 pandemic and has been widely used to investigate the impact of state policies on population health and health equity. This paper introduces the CUSP database and highlights how it is already informing the COVID-19 pandemic response in the US. CONCLUSION: CUSP is the most comprehensive publicly available policy database of health, social, and economic policies in response to the COVID-19 pandemic in the US. CUSP documents widespread variation in state policy decisions and implementation dates across the US and serves as a freely available and valuable resource to policymakers and researchers.

Impact of school closure due to the coronavirus disease 2019 pandemic on body mass index in Japanese children: Retrospective longitudinal study.

AIM: During the coronavirus disease 2019 pandemic, the governments of many countries responded to high levels of infection with lockdowns. As a result, some children were reported to experience weight gain. The aim of the present study was to examine the impact of school closures on body mass index (BMI) in Japanese children. METHODS: This was a retrospective study of students enrolled in the participating schools (6- to 11-year-old elementary school students and 12- to 14-year-old junior high school students) between 2015 and 2020. Using school health check-up data, annual changes in the BMI standard deviation score (ΔBMI-SDS) were calculated. We compared ΔBMI-SDS in 2019-2020 with the corresponding control years. RESULTS: 19 565 children with complete data were included in the analysis. Median ΔBMI-SDS in 2019-2020 were 0.24-0.35 in elementary school boys, 0.10-0.13 in junior high school boys, -0.02 to 0.15 in elementary school girls and -0.14 to -0.10 in junior high school girls. In comparison with every control year, ΔBMI-SDS in 2019-2020 were significantly higher in elementary school boys (control years: -0.07 to 0.14) and junior high school boys (control years: -0.04 to 0.06), and significantly lower in junior high school girls (control years: -0.06 to 0.09). CONCLUSION: BMI-SDS increased significantly in elementary and junior high school boys, but decreased significantly in junior high school girls. The pandemic appears to have had an impact on Japanese children that was different from other countries.

Reactive school closure weakens the network of social interactions and reduces the spread of influenza.

School-closure policies are considered one of the most promising nonpharmaceutical interventions for mitigating seasonal and pandemic influenza. However, their effectiveness is still debated, primarily due to the lack of empirical evidence about the behavior of the population during the implementation of the policy. Over the course of the 2015 to 2016 influenza season in Russia, we performed a diary-based contact survey to estimate the patterns of social interactions before and during the implementation of reactive school-closure strategies. We develop an innovative hybrid survey-modeling framework to estimate the time-varying network of human social interactions. By integrating this network with an infection transmission model, we reduce the uncertainty surrounding the impact of school-closure policies in mitigating the spread of influenza. When the school-closure policy is in place, we measure a significant reduction in the number of contacts made by students (14.2 vs. 6.5 contacts per day) and workers (11.2 vs. 8.7 contacts per day). This reduction is not offset by the measured increase in the number of contacts between students and nonhousehold relatives. Model simulations suggest that gradual reactive school-closure policies based on monitoring student absenteeism rates are capable of mitigating influenza spread. We estimate that without the implemented reactive strategies the attack rate of the 2015 to 2016 influenza season would have been 33% larger. Our study sheds light on the social mixing patterns of the population during the implementation of reactive school closures and provides key instruments for future cost-effectiveness analyses of school-closure policies.

The clinical characteristics of pediatric coronavirus disease 2019 in 2020 in Japan.

BACKGROUND: The COVID-19 pandemic has affected the lives of people of all ages. Most reports on pediatric cases suggest that children experience fewer and milder symptoms than do adults. This is the first nationwide study in Japan focusing on pediatric cases reported by pediatricians, including cases with no or mild symptoms. METHODS: We analyzed the epidemiological and clinical characteristics and transmission patterns of 840 pediatric (<16 years old) COVID-19 cases reported between February and December 2020 in Japan, using a dedicated database which was maintained voluntarily by members of the Japan Pediatric Society. RESULTS: Almost half of the patients (47.7%) were asymptomatic, while most of the others presented mild symptoms. At the time of admission or first outpatient clinic visit, 84.0% of the cases were afebrile (<37.5°C). In total, 609 cases (72.5%) were exposed to COVID-19-positive household members. We analyzed the influence of nationwide school closures that were introduced in March 2020 on COVID-19 transmission routes among children in Japan. Transmission within households occurred most frequently, with no significant difference between the periods before and after declaring nationwide school closures (70.9% and 74.5%, respectively). CONCLUSIONS: COVID-19 symptoms in children are less severe than those in adults. School closure appeared to have a limited effect on transmission. Controlling household transmission from adult family members is the most important measure for prevention of COVID-19 among children.

Mental health in Japanese children during school closures due to the COVID-19.

BACKGROUND: Changes in relationships, sleep rhythms, and physical activity caused by school closures instituted to curb the spread of COVID-19 influenced children's mental health. We explored changes in children's daily life and effects on their mental health during school closures. METHODS: Participants included elementary and junior high school students 9 years of age and older seen in the outpatient clinic during school closures and were required to complete the Japanese version of WHO Five Well-Being Index (WHO-5-J). The results were compared with those of students seen after schools reopened. RESULTS: Participants included 78 students in the school closure group and 113 in the school reopening group. Although those in the closure group devoted more time to family and sleep, their sleep rhythms, eating habits, and physical activities were disrupted. Although there were no significant differences between the two groups in total WHO-5-J scores, single WHO-5-J items such as activity and vigor and interest were significantly worse and rest was significantly better in the school closure group. CONCLUSION: Although school closures resulted in elementary and junior high school students spending more time with family and sleeping, their sleep rhythms, eating habits, and physical activities were disrupted. As the children's living environment changed, they felt less active and vigorous and had difficulty finding things that interested them. However, their sleep improved and overall, the number of children with potential mental health problems did not change.

Pediatric emergency healthcare utilization during the coronavirus disease 2019 pandemic in Tokyo.

BACKGROUND: Various public health interventions have been implemented against the coronavirus disease 2019 pandemic. We investigated changes in pediatric emergency healthcare utilization during the current pandemic. METHODS: Based on data on outpatient healthcare visits to one pediatric emergency department in Tokyo, Japan, the descriptive, cross-sectional study compared the number of emergency department visits in 2020 to the number in the previous 3 years. Data were extracted from the electronic triage reporting system. The primary outcome was the number of emergency department visits. The characteristics of patients by age group were also investigated. RESULTS: A 40.6% reduction in pediatric emergency healthcare utilization was observed during the study period, with the greatest decrease occurring in the number of visits for fever. However, while the number of patients with a complaint with an exogenous cause decreased, the proportion of these patients increased. Although social activities in the greater community have now almost normalized, and only a slight increase in the number of patients with fever has been reported, the number of emergency department visits remains lower than in previous years as of this writing. CONCLUSIONS: Public health interventions led to a reduction in emergency department visits, thereby allowing time to redistribute health-care resources.

Vulnerability and resilience in children during the COVID-19 pandemic.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is having a profound impact on the health and development of children worldwide. There is limited evidence on the impact of COVID-19 and its related school closures and disease-containment measures on the psychosocial wellbeing of children; little research has been done on the characteristics of vulnerable groups and factors that promote resilience. METHODS: We conducted a large-scale cross-sectional population study of Hong Kong families with children aged 2-12 years. Parents completed an online survey on family demographics, child psychosocial wellbeing, functioning and lifestyle habits, parent-child interactions, and parental stress during school closures due to COVID-19. We used simple and multiple linear regression analyses to explore factors associated with child psychosocial problems and parental stress during the pandemic. RESULTS: The study included 29,202 individual families; of which 12,163 had children aged 2-5 years and 17,029 had children aged 6-12 years. The risk of child psychosocial problems was higher in children with special educational needs, and/or acute or chronic disease, mothers with mental illness, single-parent families, and low-income families. Delayed bedtime and/or inadequate sleep or exercise duration, extended use of electronic devices were associated with significantly higher parental stress and more psychosocial problems among pre-schoolers. CONCLUSIONS: This study identifies vulnerable groups of children and highlights the importance of strengthening family coherence, adequate sleep and exercise, and responsible use of electronic devices in promoting psychosocial wellbeing during the COVID-19 pandemic.
