Potential health-related behaviors for pre-school and school-aged children during COVID-19 lockdown: A narrative review

Efficacy, immunogenicity and safety of CoronaVac® in children and adolescents aged 6 months to 17 years: a multicenter, randomized, double-blind, placebo-controlled phase III clinical trial

Safe and effective vaccines against COVID-19 for children and adolescents are needed. This international multicenter, randomized, double-blind, placebo-controlled, phase III clinical trial assessed the efficacy, immunogenicity, and safety of CoronaVac® in children and adolescents (NCT04992260). The study was carried out in Chile, South Africa, Malaysia, and the Philippines. The enrollment ran from September 10, 2021 to March 25, 2022. For efficacy assessment, the median follow-up duration from 14 days after the second dose was 169 days. A total of 11,349 subjects were enrolled. Two 3-μg injections of CoronaVac® or placebo were given 28 days apart. The primary endpoint was the efficacy of the CoronaVac®. The secondary endpoints were the immunogenicity and safety. The vaccine efficacy was 21.02% (95% CI: 1.65, 36.67). The level of neutralizing antibody in the vaccine group was significantly higher than that in the placebo group (GMT: 390.80 vs. 62.20, P <0.0001). Most adverse reactions were mild or moderate. All the severe adverse events were determined to be unrelated to the investigational products. In conclusion, in the Omicron-dominate period, a two-dose schedule of 3 μg CoronaVac® was found to be safe and immunogenic, and showed potential against symptomatic COVID-19 in healthy children and adolescents.

Long-term effects of the COVID-19 lockdown on weight status, eating habits, and lifestyle changes related to school-aged children in Bandar Abbas, Iran

BACKGROUND

Despite the end of the COVID-19 lockdown and reopening of schools, the long-term effects of quarantine on the weight status, eating habits, and lifestyle of children and adolescents remain unknown. This study aimed to determine the long-term effects of the lockdown on the weight status, eating habits, and lifestyle changes of children and adolescents in Iran.

METHOD

This descriptive cross-sectional study was conducted from April to May 2022. The target population comprised one hundred students aged between 10 and 16 years old. Our study obtained students' weight and height data from records maintained by school principals or physical education instructors before and after the quarantine period. The BMI z-score (zBMI) was calculated for each time point. The researchers also provided a questionnaire to collect the students' demographic and lifestyle status changes during school closures.

RESULTS

We found that the zBMI increased significantly from - 0.02 ± 1.64 to 0.36 ± 1.12, and the number of individuals with overweight and obesity increased by 3% during quarantine (P ≤ 0.05). These changes were more pronounced in males and students aged 14-16 years old. We also found that eating habits, sleeping time, sleeping patterns, screen time (time spent on social media per day), and physical activity had significant negative changes during quarantine, and a significant increase in zBMI was observed among students who experienced negative eating behaviors, altered sleeping patterns, and decreased physical activity during school closures.

CONCLUSION

As prolonged school closures due to the COVID-19 lockdown aggravated students' health and lifestyle status, our findings can aid in proper planning to establish an appropriate framework for the diet, physical activity, and sleeping quality of students during extended school closures.

Adherence of Brazilian Minors to the 24-Hour Movement Guidelines after In-Person School Return

The levels of adequacy of movement behaviors after returning to in-person school activities following the COVID-19 pandemic are not yet well understood. This study aimed to assess the adherence of Brazilian minors to the recommendations of the 24-Hour Movement Guidelines (moderate to vigorous physical activity, recreational screen time, and sleep duration), as well as overall adherence to these guidelines, after the relaxation of COVID-19 social isolation measures and the resumption of in-person schooling. A cross-sectional study was conducted with parents or guardians (39 ± 7.8) of minors aged up to 18 years of age (3.8 ± 2.5). A total of 172 individuals responded to the questionnaire. Data were compared with those obtained in the Survey of the Adequacy of Brazilian Children and Adolescents to the 24-Hour Movement Guidelines before and during the COVID-19 Pandemic. There was an 18.6 percentage decrease (p-value < 0.001) in overall adherence to the 24-Hour Movement Guidelines when comparing the periods before the COVID-19 pandemic (March 2020) and after the return to in-person schooling (March 2021). The largest percentage drop in adherence between these periods was observed for moderate to vigorous physical activity (27.4%; p-value < 0.001) and the lowest for sleep (10.5%; p-value < 0.001). Adherence to the 24-Hour Movement Guidelines did not return to pre-pandemic levels with the resumption of in-person school activities.

Comparative effects of high-intensity interval training and moderate-intensity continuous training on weight and metabolic health in college students with obesity

The purpose of this study was to compare the effects of High-Intensity Interval Training (HIIT) and Moderate-Intensity Continuous Training (MICT) on weight, body composition, blood lipid indicators, and metabolic status in college students living with obesity. The study focused on a sample of 40 college students living with obesity, including 20 males and 20 females, aged between 18 and 25. Participants were randomly assigned to either the HIIT group or the MICT group. Both groups underwent an 8-week intervention, consisting of three sessions per week with alternate-day training. The MICT group's training consisted of continuous aerobic exercise for 35 min at 60-70% of maximum heart rate. The HIIT group engaged in 28 min of alternating high-intensity and low-intensity exercise, where the high-intensity phase was at 85-90% of maximum heart rate for 4 min, followed by a 3-min recovery period at 50-60% of maximum heart rate, repeated four times. Both groups underwent heart rate monitoring before and after the training sessions to ensure the accuracy of the training intensity. Within each group, further distinctions were made based on gender, resulting in the following subgroups: Male HIIT group (n = 10), Female HIIT group (n = 10), Male MICT group (n = 10), and Female MICT group (n = 10). Differences in anthropometric and biochemical indicators among the groups were analyzed, and the different effects of the two intervention strategies on the obese college student population were comprehensively evaluated. Compared to the baseline assessment, the HIIT group showed a more favorable declining trend than the MICT group in terms of body morphology and body composition, particularly in the aspect of body fat percentage (BF%). The male HIIT group, female HIIT group, male MICT group, and female MICT group respectively reduced by - 23.71%, - 26.76%, - 9.81%, - 7.16%. Male and female HIIT group experienced a more pronounced decrease compared to the MICT group, with the female HIIT group reducing an additional 3.75% more than the male HIIT group. Regarding intergroup differences, BF% significant differences were shown between male MICT group and the HIIT group (P < 0.05), and female MICT group and the HIIT group (P < 0.01). In terms of biochemical indicators, the HIIT group also presented a more favorable declining trend compared to the MICT group, with male HIIT participants showing more reduction than female HIIT participants, especially in total cholesterol (TC) (10.64%), low-density lipoprotein cholesterol (LDL-C) (11.73%), alanine aminotransferase (ALT) (11.99%), and uric acid (UA) (11.76%). Regarding triglycerides (TG), significant intergroup differences were observed between male MICT and HIIT groups (P < 0.01) and female MICT and HIIT groups (P < 0.01). Concerning ALT, a significant difference was shown between female MICT and HIIT groups (P < 0.01), while no significant difference was observed among male participants. Overall, for college students living with obesity, both HIIT and MICT have shown positive effects. Among these, HIIT demonstrates greater effectiveness compared to MICT in BF% and biochemical markers.

Family resilience in a social-ecological context - emotional difficulties and coping strategies

Introduction

This research explored how crises such as the pandemic influence the family dynamic and the way that the parents and the children face new difficulties and challenges. The present study investigates children's and young people's emotional states, the dimensions of family resilience, and the types of coping strategies and parents' emotional states during the coronavirus pandemic. The final sample for the research was represented by 1,010 parents from Romania.

Methods

The present scientific research is a transversal study with the scope to understand the emotional difficulties that parents and children/ young people face and the coping strategies that they adopt in a crisis, such as the time of the coronavirus pandemic.

Results

Parents with maladaptive coping strategies are more affected by the pandemic. Also, the results indicate that there is a significant correlation between parental coping strategies and the children's emotional states, and the adaptability level. Therefore, the high scores on the subscales which measure maladaptive coping indicate high scores of the levels of depression, anxiety, and stress of the parents. Family resilience, through the dimension of 'communication and problem-solving in the family' has a moderation role in the relationship between parental depression and the maladaptive coping strategy of rumination. Family resilience through 'maintaining a positive attitude' has a moderation role in the relationship between catastrophizing and the teenagers' level of adaptability.

Discussion

The results of the study pointed out the role and place of family resilience within the family system and how a period of crisis can affect this system.

The "supercompensation" effect of children's lockdown during COVID-19: based on the analysis of changes in physical activity, sleep, and psychology

OBJECTIVE

To investigate the "supercompensation" effect of preschoolers during the coronavirus disease 2019 lockdown by comparing the changes in physical activity (PA), psychological, and sleep indicators before and after the lockdown.

METHODS

A total of 127 children (aged 3-6 years) were recruited. Before and after the lockdown, the children's PA levels were measured using the ActiGraph GT3X+, and their psychological and sleep indicators were measured using the Strengths and Difficulties Questionnaire (SDQ) and Child Sleep Habit Questionnaire (CSHQ), respectively.

RESULTS

Regarding PA, the children's total physical activity, low-intensity physical activity, and medium-intensity physical activity (MVPA) were higher after the lockdown than before the lockdown, with significant differences in MVPA (p < 0.05). Regarding psychology, the children's SDQ and multidimensional scores were better after the lockdown than before the lockdown, with a significant difference in SDQ scores (p < 0.05). Regarding sleep, the children's CSHQ scores were better after the lockdown than before the lockdown, with a highly significant difference in CSHQ scores (p < 0.01).

CONCLUSION

After lockdown, children's PA, psychological, and sleep effects were "supercompensated." In particular, the PA of preschoolers before, during, and after the lockdown may show a "baseline-inhibition-supercompensation" process.

Evolution of Child and Youth Mental Health in the Context of the COVID-19 Pandemic: A Longitudinal Analysis

BACKGROUND

The COVID-19 pandemic generated uncertainty and disruption among the child and adolescent population. Multiple studies have documented a worsening of mental health following the pandemic. The main objective of this longitudinal study is to analyze the short-, medium-, and long-term evolution of the overall functioning of children and adolescents treated by a child and adolescent mental health team in the context of the COVID-19 pandemic.

METHODS

420 patients aged 3 to 18 were assessed using the Global Assessment of Functioning (GAF) scale at three time points: during the lockdown, three months later, and three years later. Differences based on gender, diagnosis, and time were analyzed.

RESULTS

A significant improvement was observed in the short-term (three months) and long-term (three years) compared to the lockdown period. This improvement was maintained in all diagnostic subgroups except for mixed cases (severe mental pathology), which showed the least improvement. No significant differences were found between males and females.

CONCLUSIONS

The child and adolescent population showed a greater capacity for adaptation to the lockdown than expected. Family support, decreased stress, and therapeutic intervention appear to have played an important role in improving mental health.

Differential socioemotional and educational profiles in early childhood and primary education students in a lockdown situation

Recent lockdown situations have highlighted social relationship deprivation of schoolchildren and the need to develop the teaching-learning process in informal contexts. The aim of this study was to analyze differential socioemotional and educational profiles in Early Childhood and Primary Education students using variables relating to academic performance during the COVID-19 pandemic. Correlational, descriptive, and inferential statistical analyses were performed that yielded differential explanatory models depending on the stage of education. The results reveal statistically significant differences in all the variables except for family-school relationship. In the linear regression models, the most statistically significant variable for school performance in both stages was family-school relationship. However, differences were found between both profiles: emotional impact for Early Childhood Education students and social impact for Primary Education students. Lastly, leisure activities at home were included as an explanatory variable only in the Primary Education regression model. The final conclusions highlight the need to attend to the evolutionary characteristics of students in each stage to improve school performance in similar lockdown situations.

Effect of COVID-19 Pandemic Lockdowns on Body Mass Index of Primary School Children from Different Socioeconomic Backgrounds

BACKGROUND

Childhood obesity is associated with various health outcomes. Restrictive measures to contain the spread of the Coronavirus Disease 2019 (COVID-19) pandemic, like lockdowns and school closures, affected children's daily structure, physical activity, dietary habits, and sleep quality, possibly exacerbating risk factors for childhood obesity and higher body mass index (BMI) in children. Poor socioeconomic conditions may have led to relatively higher risk for elevated BMI levels following pandemic measures. In this study, the impact of measures related to the COVID-19 pandemic on the BMI of third graders was investigated regarding children's socioeconomic background (SEB).

METHODS

Data from 41,728 children (8.84 ± 0.56 years, 20,431 female) were collected in the context of a cohort study. Children were tested either before the pandemic (preCOVID: Sept2017-March2020, n = 26,314), or following the first (postLDI: Aug2020-Dec2020, n = 6657) or second lockdown in Germany (postLDII: Aug2021-Jan2022, n = 8757). SEB was based on the official school type classification of the state of Berlin. Outcome was BMI standard deviation scores (SDS).

RESULTS

Significant effects of Time and SEB revealed elevated BMIs in postLDI (M = 0.23, p = 0.011) and postLDII (M = 0.22, p = 0.011) compared to preCOVID (M = 0.17) cohorts and higher BMIs for children with lower SEB (b = - 0.13, p < 0.001). A significant Time × SEB interaction indicated that the effect of SEB on children's BMI increased in response to lockdowns, especially in postLDII (b = - 0.05, p = 0.006). Results suggest that the COVID-19-related measures lead to increased BMI in children, and that children of lower SEB were at particular risk for higher BMIs following lockdowns.

CONCLUSIONS

These findings highlight the dependency of children's BMI on societal circumstances. Over the course of two lockdowns in Germany, children have experienced BMI increments, particularly in low socioeconomic areas. Authorities are called into action to counteract increasing rates of childhood weight by promoting physical activity of children and establishing related post-pandemic offers.

Advances in researches on long coronavirus disease in children: a narrative review

Background and Objective

In the context of the global pandemic of coronavirus disease 2019 (COVID-19), more than 700 million infections and millions of deaths have occurred in countries around the world. Currently, two main sequelae of this disease are considered to occur in children, namely, multi-system inflammatory syndrome in children and long COVID. Among these two, the incidence of long COVID is higher and its impact on the population is more extensive, which is the focus of us. However, due to the lack of relevant studies and the limitations of most studies, the studies on sequelae of COVID-19 infection lag behind those of adults, but they have begun to attract the attention of some clinicians and researchers. We aim to summarize the current knowledge of long COVID in children, helping pediatricians and researchers to better understand this disease and providing guidance on research and clinical treatment of it.

Methods

We reviewed all the studies on "long COVID", pediatric, children, adolescent, post-COVID syndrome in PubMed published after 2019.

Key Content and Findings

This review summarizes the latest researches on epidemiology, pathogenesis, clinical manifestations, prevention and treatment of long COVID in children. Based on the existing research data, we summarized and analyzed the characteristics of long COVID in children, discovering the means to decipher the diagnosis of COVID-19 in children and some potential therapeutic treatments.

Conclusions

We aim to summarize existing research on long COVID in children and help pediatricians and government agencies quickly understand the disease so that it can be used for clinical diagnosis, treatment and prevention in the population. In addition, providing a research basis for further researches on the cellular and even molecular level to explain the occurrence and development of diseases, and has a guiding role for future research direction.

Children's behavioural and emotional wellbeing during the COVID-19 pandemic: Findings from the Born in Bradford COVID-19 mixed methods longitudinal study

Background

The COVID-19 pandemic led to a multitude of immediate social restrictions for many across the world. In the UK, the lives of children and young people were quickly impacted when COVID-19 restrictions led to school closures for most children and restrictions on social interactions. The Born in Bradford COVID-19 longitudinal research study explored the impact of the COVID-19 pandemic on the lives of children and their families living in Bradford.

Methods

Surveys were administered during the first wave of the pandemic (March to June 2020) and compared to findings from before the pandemic. The current study examined the social and emotional wellbeing of children from before to during the pandemic, measured using the parent completed Strengths and Difficulties questionnaire (SDQ). Regression analyses looked at associations between a range of social determinants of health and changes in SDQ scores.

Results

The results showed that those children most likely to experience difficulties during the pandemic were boys, younger children, those from White British ethnicity (compared to Pakistani heritage children) and those living in the most deprived areas. There were associations between experiencing difficulties and: food insecurity; financial worry; getting below recommended levels of physical activity; and having less than the recommended amount of sleep.

Conclusions

The effect of COVID-19 restrictions are likely to have had negative consequences on children that could, in time, have long-lasting impacts on the health, wellbeing and development of children in the UK.

Experiences of children and young people with attention deficit hyperactivity disorder (ADHD) during COVID-19 pandemic and lockdown restrictions

PURPOSE

To explore the experiences of children and young people (CYP) with attention deficit hyperactivity disorder during the COVID-19 pandemic and lock down restrictions.

METHODS

Semi-structured, online interviews were conducted with 17 children and young people from the UK, Northern Ireland, aged 10-14 years with ADHD. Over half the participants had a co-existing diagnosis, such as autism spectrum disorder. Interviews were recorded and transcribed verbatim before being subjected to thematic analysis.

RESULTS

Four themes were identified; the emotional impact of the pandemic, adjustments to daily living, impact of remote learning and the effect on relationships. Many CYP citied feelings of sadness, loneliness and anxiety, others found the reduction in social demands favourable.

CONCLUSIONS

As one of few studies to capture the experiences of children and young people with ADHD during the COVID-19 pandemic, this research highlights the potential negative long-term impact on emotional welfare, schooling and relationships.Implications for rehabilitationHealth care professionals should be aware of the overall impact on health and well-being for children and young people with ADHD following the COVID-19 pandemic and lockdown restrictions to ensure that the effect of these are minimised and managed in the future.Educators and clinicians should be cognisant of the long term consequences of poor mental health during the COVID-19 pandemic and should put in place pro-active strategies to support children and young people with ADHD.Children and young people with ADHD may suffer greatly from reduced access to sports and leisure facilities. Policy makers should be conscious of the potential negative consequences of placing limitations on access to such facilities.

Impact of lockdown on the growth of children in China aged 3-6 years during the COVID-19 pandemic

Background

Lockdowns in COVID-19 pandemic led to less physical activity and more intake of unhealthy food in children. The aim of this study was to investigate the negative impact of major lockdowns on the growth of children aged 3-6 years during COVID-19 pandemic period.

Methods

Physical examination results in 2019 to 2022 from 5834 eligible children (2972 males and 2862 females) from Southwestern China who were 3 years old in 2019 were retrospectively collected. Height and weight data points were extracted from the results, and percentiles of height (height%), weight (weight%), and BMI (BMI%), and rates of overweight and obesity were calculated and compared between different years during the pandemic.

Results

After analyzing the 15404 growth data points from 5834 children, a slowly increasing trend of height% from 2019 to 2022 was observed. Weight%, BMI%, overweight rate, obesity rate, and combined overweight and obesity rate had two peaks in 2020 and 2022 when major lockdowns were adopted and a drop in between (year 2021), except for obesity rate which did not drop in 2021. Similar results were shown after stratification by gender.

Conclusion

The lockdowns in COVID-19 pandemic promoted obesity of kindergarten children, but did not show any negative impact on their height growth possibly due to over-nutrition of children during lockdowns. More efforts need to be made to limit the increase of obesity rate in kindergarten children during possible future lockdowns.

The impact of the COVID-19 pandemic on children's occupations

Background

The COVID-19 pandemic changed the daily lives and limited everyday activities of children worldwide.

Objectives

To document the impact of the COVID-19 pandemic on children's occupations, the associated factors, and the impact on children's health, wellbeing, and development.

Methods

A narrative review was conducted by searching four databases (Scopus, MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews).

Results

A total of 35 articles met the inclusion criteria. Out of the 34 articles, 23 were relevant to the impact of the COVID-19 pandemic on occupations related to leisure (n = 17), productivity (n = 11), and self-care (n = 9). Ten articles highlighted specific factors that had been linked to changes in occupational engagement and child behavior. Ten articles focused on the impact of occupational disruption during COVID-19 on health, wellbeing, and general development.

Conclusion

The COVID-19 pandemic seems to have had a negative impact on children's occupations, while the restrictions were still in effect. Further research is needed to establish reliable conclusions.

Determining the Impact of Lifestyle on the Health of Primary School Children in Slovenia Through Mixed Membership Focus Groups

Lifestyle choices made by children and adolescents can lead to a variety of health problems. It is therefore crucial to evaluate the state health-related lifestyles of primary school children's and identify areas for improvement. The aim of this study was to investigate the experiences and perspectives of those involved in educating current generations of primary school children about their lifestyle and the associated health implications of their behavior. Four focus groups were formed, comprising parents, primary school teachers, health professionals, and leisure activity teachers, with five participants in each group. Semi-structured interviews were conducted with each group as part of the qualitative research paradigm of the study. The study revealed three central themes, emphasizing the need to promote health and educate children about healthy behaviors, environmental influences, and health literacy. Community nurses need to take a proactive role in promoting school health. Although adults, peers, and the environment exert a strong influence on children's lifestyles, they often fail to live up to their responsibilities and allow harmful habits to form. To instill positive behaviors and an optimistic attitude towards a healthy lifestyle, all those involved in a child's education need to collaborate. Health-related topics should be included or reinforced in primary school curricula, and parents and school staff should receive appropriate training.

Children's Daily Living Routine Mediates the Relations Between Parent-Child Relationships and Child Adjustment Problems During School Suspension in Hong Kong

Young children's adjustment problems were found to be prevalent during the COVID-19 pandemic. Such adjustment problems may be dependent on children's relationships with their parents and children's daily living routine in the family during the pandemic-related school suspension period. This study examines how children's routine mediated the associations between parent-child relationships and child adjustment problems during the fifth wave of the COVID-19 pandemic in Hong Kong, when schools were suspended. The study collected data from 937 parents (87.8% mothers) of children aged 5-12 (M = 7.35 years, SD = 2.09; 50.5% girls). Parents reported on parent-child relationships, children's daily living routine, and child adjustment problems in an online survey. Our findings from structural equation modeling indicate that parent-child closeness was negatively related to child adjustment problems, whereas conflict was positively related to child adjustment problems. Children's routine mediated the associations between parent-child relationships (i.e., closeness and conflict) and child externalizing problems. However, children's routine did not mediate the associations between parent-child relationships (i.e., closeness and conflict) and child internalizing problems. The findings show that parents should be helped to establish routine, especially in difficult times when young children experience turbulence in their daily life, so as to reduce their adjustment problems, in particular of an externalizing nature.

Motor Competence between Children with and without Additional Learning Needs: A Cross-Sectional Population-Level Study

The aim of this study was to examine associations in motor competence between children with additional learning needs (ALN) and typically developing children. This cross-sectional study involved a nationally representative cohort of 4555 children (48.98% boys; 11.35 ± 0.65 years) from sixty-five schools across Wales (UK). Demographic data were collected from schools, and children were assessed using the Dragon Challenge assessment of motor competence, which consists of nine tasks completed in a timed circuit. A multi-nominal multi-level model with random intercept was fitted to explore the proficiency between children with ALN and those without. In all nine motor competence tasks, typically developing children demonstrated higher levels of proficiency than their peers with ALN, with these associations evident after accounting for age, sex, ethnicity, and socioeconomic status. This study highlights motor competence inequalities at a population level and emphasises the need for policymakers, practitioners, and researchers to prioritise motor competence development, particularly for children with ALN.

Comparison between virtual and hybrid education for psychological factors and academic stress in freshman nursing students: a case-control study

BACKGROUND

The coronavirus 2019 (COVID-19) pandemic has prompted several changes in the learning methods of students. The purpose of this study was to establish whether a relationship between levels of resilience, self-esteem, anxiety, depression, and academic stress in both hybrid and virtual learning education exist.

METHODS

A descriptive and observational case-control study was carried out in universities that offer nursing designation. A total sample of 140 freshman nursing students was recruited. Concretely, 70 participants were recruited from an university receiving hybrid education and 70 participants were recruited from another university receiving virtual learning education. Nursing students self-reported the following questionnaires: the Rosenberg Self-Esteem scale, the 10 CD-Risk Connor-Davidson Risk Resilience Scale, the Beck Anxiety Inventory, the Beck Depression Inventory and the Academic Stress Coping Scale.

RESULTS

Significant differences (P = 0.001) showed higher depression levels for students who received virtual education versus received hybrid education. Differences in Rosenberg test for self-esteem and Beck Anxiety Inventory for anxiety (P > 0.05) were not found.

CONCLUSION

Students who received online education presented higher depression levels which could be due to they had not face-to-face relationships with teachers or classmates, whereas the hybrid education group received a different type of direct interaction with teachers and peers.

The impact of the COVID-19 pandemic on inequalities in lifestyle behaviours and mental health and wellbeing of elementary school children in northern Canada

Objectives

The COVID-19 pandemic has negatively affected children's lifestyle behaviours and mental health and wellbeing, and concerns have been raised that COVID-19 has also increased health inequalities. No study to date has quantified the impact of COVID-19 on health inequalities among children. We compared pre-pandemic vs. post-lockdown inequalities in lifestyle behaviours and mental health and wellbeing among children living in rural and remote northern communities.

Methods

We surveyed 473 grade 4-6 students (9-12 years of age) from 11 schools in rural and remote communities in northern Canada in 2018 (pre-pandemic), and 443 grade 4-6 students from the same schools in 2020 (post-lockdown). The surveys included questions on sedentary behaviours, physical activity, dietary intake, and mental health and wellbeing. We measured inequality in these behaviors using the Gini coefficient, a unitless measure ranging from 0 to 1 with a higher value indicating greater inequality. We used temporal changes (2020 vs. 2018) in Gini coefficients to assess the impact of COVID-19 on inequalities in lifestyle behaviours and mental health and wellbeing separately among girls and boys.

Results

Inequalities in all examined lifestyle behaviours increased between 2018 and 2020. Inequalities in watching TV, playing video games, and using a cell phone increased among girls, while inequalities in playing video games, using computers and tablets, and consumption of sugar, salt, saturated fat and total fat increased among boys. Changes in inequalities in mental health and wellbeing were small and not statistically significant.

Conclusion

The findings suggest that the COVID-19 pandemic has exacerbated inequalities in lifestyle behaviours among children living in rural and remote northern communities. If not addressed, these differences may translate into exacerbated inequalities in future health. The findings further suggest that school health programs can help mitigate the negative impact of the pandemic on lifestyle behaviours and mental health and wellbeing.

Dilemmas and options for COVID-19 vaccination in children

Over 16 million children have been detected positive for the coronavirus disease 2019 (COVID-19) in the United States since the outbreak of the pandemic. In general, children infected with severe acute respiratory syndrome coronavirus type 2 tend to have lighter symptoms than adults. However, in some cases, the infection can develop into severe forms, such as multisystem inflammatory syndrome in children. Moreover, long-term public health preventive interventions have had some negative effects on the physical and mental health of children. Given the important role that vaccination plays in reducing severe illness and mortality, it is essential for the efficient implementation of vaccination in the pediatric population. Nevertheless, parental distrust of vaccination, especially with regard to its safety and efficacy, hinders this process. Herein, we comprehensively summarize the available data on the safety and effectiveness of COVID-19 vaccine in children. The results show that the currently approved COVID-19 vaccine is safe and effective for children. Although two doses of vaccine in children seem insufficient to prevent Omicron infection, the booster dose provides enhanced protection against infection and severe illness. Most importantly, the bivalent vaccine has been approved for use in the pediatric population to extend the immune response to currently circulating Omicron variant. And the immune protection afforded to newborns after maternal vaccination appears to last only 6 months. Therefore, in the current situation where the rate of virus mutation is accelerating and the COVID-19 pandemic is still severe, it is crucial to extend vaccine protection to children over 6 months of age to weave a tighter safety net.

Effect of the COVID-19 pandemic on emergency department attendances for pediatric injuries in Mozambique's central hospitals: an interrupted time series and a comparison within the restriction periods between 2019 and 2020

Objectives

Hospital-based studies indicate that restriction measures imposed during the COVID-19 pandemic have affected the number and characteristics of pediatric injuries. However, few studies have been conducted in resource-poor countries. This study aimed to determine whether injury-related emergency department (ED) attendances in Mozambique were affected during the restriction periods in 2020 and how the pattern of injury changed.

Methods

Mozambique faced two restriction periods in 2020. An interrupted time series was applied to weekly data of pediatric injuries from the ED records of four central hospitals in Mozambique in 2019 and 2020. Weekly numbers of injuries were modeled using a Poisson regression model to estimate the effect of COVID-19 restrictions on trends over calendar time. Then, for each restriction period, differences in injury mechanisms, severity, need for surgery, and intensive care unit (ICU) attendances were compared between 2019 and 2020.

Results

During the 76 weeks preceding the restrictions, there was a stable trend in ED attendances. The weekly number dropped by 48.7% after implementation of the first restrictions. By the end of 2020, the weekly numbers were back to the levels observed before the restrictions. Road traffic injuries (RTIs) and falls dropped during the first restriction period and RTIs and burns during the second. There was an increase of 80% in ICU attendances in all periods of 2020 at three hospitals during the first and second restriction periods.

Conclusion

The COVID-19 restrictions yielded a reduction in the weekly number of pediatric injuries seen at Mozambique's central hospitals, above all RTIs and falls. The drop reflects reductions in visits most importantly for RTIs, falls, and burns, but was accompanied by an increase in the proportion of ICU cases. This effect was not maintained when the restrictions were relaxed. Whether this reflects reduced exposure to injury or hesitancy to seek care remains to be determined.

Level of evidence

Level III, retrospective study with up to two negative criteria.

Device-Measured Change in Physical Activity in Primary School Children During the UK COVID-19 Pandemic Lockdown: A Longitudinal Study

BACKGROUND

Lockdown measures, including school closures, due to the COVID-19 pandemic have caused widespread disruption to children's lives. The aim of this study was to explore the impact of a national lockdown on children's physical activity using seasonally matched accelerometry data.

METHODS

Using a pre/post observational design, 179 children aged 8 to 11 years provided physical activity data measured using hip-worn triaxial accelerometers worn for 5 consecutive days prepandemic and during the January to March 2021 lockdown. Multilevel regression analyses adjusted for covariates were used to assess the impact of lockdown on time spent in sedentary and moderate to vigorous physical activity.

RESULTS

A 10.8-minute reduction in daily time spent in moderate to vigorous physical activity (standard error: 2.3 min/d, P < .001) and a 33.2-minute increase in daily sedentary activity (standard error: 5.5 min/d, P < .001) were observed during lockdown. This reflected a reduction in daily moderate to vigorous physical activity for those unable to attend school (-13.1 [2.3] min/d, P < .001) during lockdown, with no significant change for those who continued to attend school (0.4 [4.0] min/d, P < .925).

CONCLUSION

These findings suggest that the loss of in-person schooling was the single largest impact on physical activity in this cohort of primary school children in London, Luton, and Dunstable, United Kingdom.

Dramatic increase of suicidality in children and adolescents after COVID-19 pandemic start: A two-year longitudinal study

The COVID-19 pandemic has impacted the mental health of the youngest, worsening their emotional well-being. The demand for care in psychiatric emergencies may indirectly reflect the mental health state of children and adolescents and the emotional consequences of the pandemic. Moreover, suicidality can be considered a marker of severity in this population group. Therefore, we have aimed to longitudinally describe the number of children and adolescents attended in the psychiatry emergency department due to suicidal ideation or attempts and, to explore differences in suicidality according to gender and age. A retrospective study was carried out in the University Hospital of San Juan, Alicante, Spain, from January 01, 2018 to December 31, 2021. A total of 138 participants under 18 years requesting psychiatric care due to suicidal ideation or attempts were included. The sample was composed by 35% of males and the mean age was 14.8 years old (SD = 2.2). The number of cases per year range from 10 in 2018 to 88 in 2021. Attendances were significantly higher between 2021 and the three previous years. Besides, the number of attentions registered in the last 9 months of 2021 equals those that occurred in the entire previous period. Most of the cases were girls and middle adolescents. Suicide ideation or attempts have skyrocketed in children and adolescents. This alarming increase presents a one-year lag peak from the COVID-19 outbreak and continues until the end of 2021. Girls and those over 12 years have been identified as risk groups to present suicidal ideation or attempts.

Overweight/obesity and socio-demographic disparities in children's motor and cognitive function

Fundamental motor skills (FMS) and cognitive function are important indicators of development in early childhood. Using a cross-sectional design, the purpose of this study was to investigate obesity (healthy weight vs. overweight/obese) and socio-demographic (i.e., gender, SES) disparities in FMS (locomotor and ball skills) and cognitive function (reaction time [RT] and movement time [MT]), in preschoolers. There were 74 preschoolers (girl = 38; M_age = 4.02 ± 0.73) recruited from two childcare centers and were categorized into healthy weight (n = 58, BMI percentile < 85%) and overweight/obese (n = 16, BMI percentile ≥ 85%) categories. Children's FMS were assessed using the TGMD-3; cognitive function was assessed by the iPad-based CANTAB™ software using the Reaction Time Task (RTI), including reaction time (RT; Simple RT [SRT], choice RT [CRT]) and movement time (MT; simple MT [SMT], choice MT [CMT]). Children presented less FMS proficiency compared to recent data. Both weight groups performed comparably in FMS (ps > 0.05; ball skill Cohen's d = 0.40; locomotor Cohen's d = 0.02). Children in the overweight/obese group performed significantly worse on all cognitive tests compared to healthy weight peers (ps < 0.05; Cohen's d range from -0.93 to -1.43). No significant gender or SES disparities were observed. Maintaining healthy weight status is critical for cognitive development among preschoolers, which may influence their developmental trajectory and school readiness.

Psychosocial Problems Among Primary School Children in Thailand During the COVID-19 Pandemic, 2022

Background

During the COVID-19 pandemic, primary school children are particularly vulnerable as restriction measures have caused a huge impact on their health and well-being. This study aims to assess the prevalence of mental health among primary school children in Thailand during the COVID-19 pandemic and identify factors associated with psychosocial problems.

Methods

A survey was conducted among 701 Thai parents of primary school children from January to March 2022 - when teaching modalities between onsite and online learning were alternated. Parents were requested to assess the mental health of their youngest child at primary school age level. Psychosocial problems were measured by the Strengths and Difficulties Questionnaire (SDQ) with a total score of 40, based on 4 domains (emotion, behavior, hyperactivity, and relationship). Independent variables included (1) parental/household factors, (2) children characteristics, and (3) online learning-related issues. The dependent variable was the prevalence of children with a total score of 14-40, which indicates at risk and/or having mental health problems. The analysis was performed using logistic regression model.

Results

Thai parents reported that 41.1% of children had psychosocial problems. Children in a single-parent family (adjusted odds ratio [AOR] = 1.7; 95% confidence interval (CI) = 1.1-2.8), male children (AOR = 1.7, 95% CI = 1.2-2.4), and children who did not receive adequate assistance for online learning from their parents (AOR = 2.1, 95% CI = 1.1-4.0) significantly faced greater odds of mental health problems.

Conclusion

The prevalence of Thai primary school children confronting psychosocial difficulties during the COVID-19 pandemic increased, with significant concern. Public health interventions that aim to protect the mental health of primary school children during the pandemic should be introduced and targeted male children and those living with a single parent. Social support that facilitates online learning for children whose parents have limited capacity in supporting them should be implemented.

Survey of the Adequacy of Brazilian Children and Adolescents to the 24-Hour Movement Guidelines before and during the COVID-19 Pandemic

The 24-Hour Movement Guidelines provide specific recommendations on movement behaviors for children and adolescents. The objective of this study was to verify the adequacy of children and adolescents to the guidelines for moderate to vigorous physical activity, recreational screen time, and sleep duration, and the overall adequacy to the guidelines, before and during the COVID-19 pandemic. A cross-sectional study was conducted with parents or guardians of children or adolescents from different regions of Brazil using a digital interview form including sociodemographic characteristics of families, moderate to vigorous physical activity, recreational screen time, and sleep duration before and during the pandemic. Statistically significant variation was observed in both groups in relation to moderate to vigorous physical activity and recreational screen time between the two periods evaluated. Overall adequacy to the guidelines before the pandemic was 19.28% for children from Group 1 (0-5 years old) and 39.50% for those from Group 2 (6 to 17 years old). During the pandemic, it corresponded to 3.58% in Group 1 and 4.94% in Group 2 (p-value between periods ≤0.001). This study showed the significant impact of pandemic restrictions on reducing overall compliance and physical activity, and increasing screen time among Brazilian children and adolescents.

Predicting preschool children's digital play addiction tendency during Covid-19 pandemic: Regarding the mother-child relationship, and child- and family-related factors

Previous research about children's digital play has predominantly focused on parental perspectives and parental mediation strategies. Although research on the effects of digital play on young children's development is plentiful, there is little evidence on young children's digital play addiction tendency. Herein, preschool children's digital play addiction tendency, and the mother-child relationship perceived by mothers, examining child- and family-related factors were explored. The present study also aimed to contribute to the current research pertaining to preschool-aged children's digital play addiction tendency through an examination of the mother-child relationship, and child- and family-related factors as potential predictors of children's digital play addiction tendency. A sample of 450 mothers of children between 4 and 6 years filled out two measures that identify the mother-child relationship and children's digital play addiction tendency. Correlational analyses revealed that in general, the mother-child relationship was significantly associated with children's digital play addiction tendency. Significant differences were evident in the relationship between numerous child- and family-related factors, and children's digital play addiction tendency, as well as the mother-child relationship. Hierarchical regression analyses indicated that a negative mother-child relationship, the children's digital play usage, and the mothers' digital device usage predicted the children's digital play addiction tendency.

Self-Reported Anxiety and Depression among Parents of Primary School Children during the COVID-19 Pandemic in Thailand, 2022

One significant concern during the COVID-19 pandemic is parents' mental health, which may consequently affect children's health and well-being. The objective of this study is to investigate generalized anxiety and depression in parents of primary-school-aged children and identify risk factors for mental health problems. A cross-sectional survey comprising 701 parents of primary school children in five of Thailand's major provinces was carried out from January to March 2022. Generalized anxiety and depression levels were assessed using the GAD-7 and PHQ-9. Logistic regression was performed to determine the effects of independent variables on anxiety and depression. Results showed that the prevalence of generalized anxiety and depression was 42.7% and 28.5%, respectively, among Thai parents. Three strong associative factors included: (1) having a youngest child with mental health problems; (2) not assisting their children every day; and (3) drinking alcohol. These findings show that the parents must deal with several difficulties when trying to maintain work and parenting duties while being confined at home during emergency situations. The government should provide sufficient assistance to parents who lack skills in handling children with emotional and behavioral problems. Meanwhile, health promotion to reduce alcohol consumption should continue to be an area of focus.

Impact of the COVID-19 Pandemic on Nutrition, Sleep, Physical Activity, and Mood Disorders of Polish Children

The harmful consequences of the COVID-19 pandemic on children are its impact on eating habits, physical activity, sleep, and mood disorders. In the future, this may result in a higher prevalence of obesity and diet-related diseases. Therefore, this study aimed to assess the impact of the COVID-19 pandemic on children's eating behavior and lifestyle. The study was conducted using a proprietary questionnaire on dietary and lifestyle habits before and during the pandemic, and the reasons for changes due to the pandemic. The study involved 294 parents of children in grades 1-8 in elementary schools in two regions of Poland. The survey showed that during the pandemic, the percentage of children eating five regular meals daily, including fruits and vegetables, and engaging in daily physical activity decreased. However, the percentage of children spending more than 4 h a day in front of a screen increased (p < 0.05). The main reasons for changes in eating habits and physical activity were less eating out, lack of motivation, obstruction, and lack of access to sports facilities (p < 0.05). The pandemic had a significant impact on reduced levels of physical activity and increased time spent in front of a screen. In summary, among the reasons for changes in children's dietary and lifestyle habits, factors related to the pandemic itself, i.e., social restrictions, restrictions, closure of schools and other facilities, and fear of coronavirus infection, had the greatest impact.

Parental Worry About COVID-19 in Preschool Children's Mothers During the Pandemic Waves: The Role of Maternal Negative Feelings and Parenting Styles

This cross-sectional study explores the relationship between maternal feelings, maternal parenting styles, and mothers' worry about COVID-19's detrimental consequences on preschool children's health and well-being. The study is among the first to concentrate on this reference specific group, whose characteristics might be particularly vulnerable to COVID-19's adversities. One hundred and four mothers of at least one preschool-age child completed an online questionnaire battery, which included the Parental Feelings Inventory, the Parenting Styles and Dimensions Questionnaire (PSDQ), and the parental worry about COVID-19 scale. Negative maternal feelings (i.e., anger, anxiety/sadness) were associated with authoritarian and indulgent parenting practices, especially verbal hostility, while maternal happiness was associated with more authoritative practices, especially warmth and support. The hierarchical multiple regression model explained about 42% of variance of the overall maternal worry about COVID-19 from maternal negative feelings and parenting styles, with maternal authoritative parenting and maternal anxiety/sadness as the significant predictors that uniquely explain maternal worry about COVID-19. These results are discussed in terms of positive and negative maternal worry, which partially reflect the differences between overprotective and authoritative parenting in early childhood.

Impact and recovery of the COVID-19 pandemic on weight status of children and adolescents

Recent evidence suggests the immediate effects of the COVID-19 lockdowns and restrictions have resulted in increased weight in children and adolescents. However, the longer-term effects have not been assessed. The aim of this study was to examine the impact and longer-term effects of the COVID-19 pandemic on BMI and weight status of children and adolescents. This study used routinely collected clinical data from the Sydney Children's Hospitals Network, comprising two socio-demographically diverse children's hospitals in New South Wales, Australia from 2018 to 2021. Of 245 836 individuals ≤18-years assessed, mean BMI percentile increased from 58.7 (SD 31.6) pre-COVID-19 to 59.8 (SD 31.7) (p < .05) post-restrictions and overweight/obesity increased by 5.5% (obesity alone 6.3%), predominantly in children <12-years and from lower socioeconomic backgrounds. The trend in BMI percentile was steady pre-COVID-19 (β = -0.03 [95% CI -0.07, 0.01]), peaked immediately following COVID-19 restrictions (β = 1.28 [95% CI 0.24, 2.32]) and returned to pre-pandemic levels over ensuing 21 months (β = -0.04 [95% CI -0.13, 0.04]). Routine anthropometric measurement facilitates ongoing monitoring and evaluation of the weight status of children and adolescents, helping to identify those at-risk. Despite initial BMI and weight increases among children and adolescents, longer-term follow-up highlighted a return to pre-pandemic rates, possibly attributed to state-wide policies aimed at reducing childhood obesity.

COVID-19: Insights into long-term manifestations and lockdown impacts

Coronaviruses are pathogens thought to primarily affect the respiratory tracts of humans. The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2019 was also marked mainly by its symptoms of respiratory illness, which were named coronavirus disease 2019 (COVID-19). Since its initial discovery, many other symptoms have been linked to acute SARS-CoV-2 infections as well as to the long-term outcomes of COVID-19 patients. Among these symptoms are different categories of cardiovascular diseases (CVDs), which continue to be the main cause of death worldwide. The World Health Organization estimates that 17.9 million people die from CVDs each year, accounting for ∼32% of all deaths globally. Physical inactivity is one of the most important behavioral risk factors for CVDs. The COVID-19 pandemic has affected CVDs as well as the physical activity in different ways. Here, we provide an overview of the current status as well as future challenges and possible solutions.

Joys or Sorrows of Parenting During the COVID-19 Lockdown: A Scoping Review

Objectives: The aim of this scoping review was to map out the existing evidence of the impact of the COVID-19 lockdown on parents of children and adolescents. We sought to: 1) identify parenting domains that were particularly affected by lockdown measures, 2) describe the challenges and opportunities of lockdown measures in these domains, and 3) define protective and exacerbating factors modulating the effect of lockdown measures on parents. Methods: We identified five main domains investigated in the context of parenting during the early COVID-19 lockdown derived from 84 studies: health and wellbeing, parental role, couple functioning, family and social relationships, and paid and unpaid work. For each domain, we listed challenges and opportunities, as well as discriminant factors. Results: The lockdown impacted all five different but interconnected domains, introduced new roles in parents' lives, and particularly affected women and vulnerable populations. Conclusion: This scoping review highlights the importance of approaching public health policymaking from a social justice perspective. Such an approach argues for social and public health policies to promote health accounting for its social, economic, political, and commercial determinants.

Changes in cardiovascular risk factors among children and young adults with type 1 diabetes during the COVID-19 pandemic compared to previous years-Results from the German DPV registry

BACKGROUND

The diverse stages of the COVID-19 pandemic led to several social circumstances that influenced daily life and health behavior.

PURPOSE

To evaluate changes in cardiovascular risk factors and physical activity among children and young adults with type 1 diabetes (T1D) during the COVID-19 pandemic in Germany compared to previous years.

METHODS

A total of 32 785 individuals aged 6-21 years at baseline with T1D from the German diabetes patient follow-up (DPV) registry contributed data on 101 484 person-years between 2016 and 2021. The first treatment year of each individual within this period was considered as baseline. Based on trends from 2016 to 2019, we estimated differences in body mass index-SD score (BMI-SDS), blood pressure (BP-SDS), and lipid levels (non-high-density lipoprotein [non-HDL]) between observed and predicted estimates for the years 2020 and 2021 using linear regression analysis standardized for age, diabetes duration, sex, and migratory background. The proportion doing organized sports and smoking cigarettes was analyzed using multivariable logistic regression models.

RESULTS

BMI-SDS increased constantly from 2016 to 2021 without a significant increase above expected values for 2020/2021. Systolic BP-SDS (difference observed vs. expected with 95% confidence interval, 2020: 0.10 [0.07-0.14], 2021: 0.17 [0.14-0.20]) and non-HDL (2020: 2.7 [1.3-4.1] mg/dl, 2021: 4.1 [2.7-5.5] mg/dl) were significantly increased (all p < .001) in both pandemic years. The proportion of subjects participating in organized sports was reduced from over 70% in prepandemic years to 35%-65% in diverse stages/waves of the COVID-19 pandemic. The percentage smoking cigarettes did not change.

CONCLUSIONS

We describe an increase in BP and atherogenic lipid levels coinciding with a reduction in physical activity but no acceleration of the prepandemic increases in BMI-SDS among young people with T1D during the COVID-19 pandemic.

Physical Activity and Screen Viewing Behaviors Among Children Aged 6-9 Years During the COVID-19 Pandemic

BACKGROUND

The COVID-19 pandemic resulted in many restrictions worldwide, including lockdowns and school closures. This may have prevented children from meeting the recommended physical activity (PA) levels and screen time. The aim of this study was to examine the impact of the pandemic on school-age children's PA and screen time in Saudi Arabia.

METHODS

A cross-sectional study where caregivers of children aged 6-9 years living in Saudi Arabia were recruited through convenience sampling to fill out an online survey between July and August 2020. The survey covered demographic information, PAs, and screen time across 3 periods: pre-COVID-19 pandemic, during the COVID-19 lockdown, and the last 7 days preceding the survey during the pandemic where social distancing applied, but no lockdown.

RESULTS

A total of 339 caregivers completed the online survey about their children. The number of active children slightly increased during the lockdown (9.7%) than before COVID-19 and the last days (5.8%); however, the average reported days of PA during the pandemic were fewer than before. The findings indicated that all 3 types of screen time (watch time, screenplay, and device time) were longer during the pandemic (mean [SD]: 9.5 [5.5]) than before the COVID-19 (mean [SD]: 5.8 [5.1]).

CONCLUSION

While the proportion of active children had increased during the lockdown, the COVID-19 pandemic, the COVID-19 pandemic negatively impacted PA days and screen time in school-age children. School-age children in Saudi Arabia were already far from meeting global guidelines even before the pandemic, highlighting this population's need for healthy lifestyle promotion.

Changes in Lifestyle Behaviors of Children and Adolescents during the COVID-19 Pandemic and the Impact on the Development of Non-Communicable Diseases: A Narrative Review

Background: Quarantine restrictions have changed the usual lifestyle habits of children and adolescents. In this review, we summarize how the COVID-19 outbreak changed lifestyle during childhood and discuss potential short- and long-term effects of NCD high-risk behaviors on health outcomes. Methods: literature search was conducted in Medline database (PubMed), Scopus, Embase, Web of Science, and Google Scholar. All studies that assessed the relationship between COVID-19 outbreak and lifestyle changes were included. Results: NCD risk factors such as unhealthy diet, physical inactivity, prolonged screen time and sedentary behavior, disrupted sleep schedules and sleep quality, as well as mental disorders during COVID19 in childhood, may increase the susceptibility to NCDs in adulthood. These changes in lifestyle behaviors have short and long-term cardio-metabolic and psychological health outcomes. Since it is not clear when COVID-19 is completely controlled, assessment of the interactions between COVID-19 and lifestyle activities in the pediatric age group is critical. Conclusion: The pandemic of coronavirus disease 2019 (COVID-19) has greatly influenced all levels of health systems. During the COVID-19 pandemic, prevention and management of non-communicable diseases (NCDs) will need to be prioritized even further.

Unusual Experience in the COVID-19 Pandemic: Young Children's Readjustment from Home to Preschool following School Closures in Different Risk Regions

Children's readjustment to preschool following long-term school closures during the COVID-19 pandemic merits special attention. This study examined children's preschool readjustment using a survey of 1008 teachers in a high-risk region and 1399 teachers in a fluctuating-risk region of China. Results found are as follows. (1) children's preschool readjustment was at a medium level after the long-term school closures. However, children's preschool readjustment scores in the fluctuating-risk region were significantly lower than those in the high-risk region. (2) Children in both regions were divided into four profiles based on their preschool readjustment: low-level, middle-level, upper-middle-level, and high-level groups. (3) Preschool transition practices and teachers' turnover intention are common factors relating to preschool readjustment in both regions. Teachers' professional development support impacted children's preschool readjustment only in the high-risk region. The findings inform the design of targeted interventions to help children readjust to preschool across different risk regions.

Physical Well-Being of Children and Adolescents during the SARS-CoV-2 Pandemic: Findings from the "Come te la Passi?" Cross Sectional Survey in Bologna, Italy

BACKGROUND

The COVID-19 had a strong impact on the physical and general well-being of the youngest. In Italy, citizens were forced to change their habits, especially during the national lockdown, causing increased levels of sedentary and unhealthy behaviors. "Come te la passi?" was a cross-sectional study aimed at investigating changes in the physical activity levels (PA) and well-being of children and adolescents in the City of Bologna.

METHODS

An anonymous survey was administered to parents/guardians of children and adolescents aged 6-18 years.

RESULTS

1134 questionnaires were collected during June 2021; 457 (40.3%) were females, and the mean age was 13.0 ± 3.4 years. Regarding the general well-being perception, 61.3% of the participants reported concerns about the future, 46.3% reported sleep difficulties, and 72.8% reported experiencing attention difficulty, with higher percentages among adolescents. Considering the PA frequency, an overall reduction was found, with the percentage of those who rarely did PA and those who frequently did PA both increasing. No gender differences were found.

CONCLUSIONS

Our findings suggest that the current pandemic has strongly impacted the well-being of children and adolescents. It appears to have primarily affected adolescents, with a significant reduction in PA levels, even after the end of the national lockdown.

Persistence of Lockdown Consequences on Children: A Cross-sectional Comparative Study

Lockdown during the COVID-19 pandemic had a significant psychological impact on children and adolescents. This study compared lockdown effects on children aged 1-10 years in 2020 and 2021. Two structured questionnaires were administered to 3392 parents in 2020, and 3203 in 2021. Outcomes considered for the data analysis included sleep changes, episodes of irritability, attention disturbances, distance learning and number of siblings. For data analysis, children were divided into two groups: pre-scholar (1-5 years old) and older ones. The lockdown was associated with a significant increase in sleep disturbances in 2020 and persisted after a year. The high prevalence of mood changes persisted unchanged in children under the age of 10 in 2020 and in 2021. Even if strengthened family ties seemed to mitigate the negative impact of lockdowns in 2020, this effect appeared absent or at least reduced in 2021. Irritability and rage in children were perceived to have increased in 2021 compared to 2020. A significant reduction in digital device use was observed in 2021 compared to 2020. Overall, the most harmful consequences of the lockdown in 2020 were still observed in 2021. Further studies are needed to analyze possible psychological effects that the generation who experienced the pandemic during early childhood may have, particularly in their future adolescence, in order to identify possible intervention practices to support families.

Modeling the impact of surveillance activities combined with physical distancing interventions on COVID-19 epidemics at a local level

Physical distancing and contact tracing are two key components in controlling the COVID-19 epidemics. Understanding their interaction at local level is important for policymakers. We propose a flexible modeling framework to assess the effect of combining contact tracing with different physical distancing strategies. Using scenario tree analyses, we compute the probability of COVID-19 detection using passive surveillance, with and without contact tracing, in metropolitan Barcelona. The estimates of detection probability and the frequency of daily social contacts are fitted into an age-structured susceptible-exposed-infectious-recovered compartmental model to simulate the epidemics considering different physical distancing scenarios over a period of 26 weeks. With the original Wuhan strain, the probability of detecting an infected individual without implementing physical distancing would have been 0.465, 0.515, 0.617, and 0.665 in designated age groups (0-14, 15-49, 50-64, and >65), respectively. As the physical distancing measures were reinforced and the disease circulation decreased, the interaction between the two interventions resulted in a reduction of the detection probabilities; however, despite this reduction, active contact tracing and isolation remained an effective supplement to physical distancing. If we relied solely on passive surveillance for diagnosing COVID-19, the model required a minimal 50% (95% credible interval, 39-69%) reduction of daily social contacts to keep the infected population under 5%, as compared to the 36% (95% credible interval, 22-56%) reduction with contact tracing systems. The simulation with the B.1.1.7 and B.1.167.2 strains shows similar results. Our simulations showed that a functioning contact tracing program would reduce the need for physical distancing and mitigate the COVID-19 epidemics.

The COVID-19 Sentinel Schools Network of Catalonia (CSSNC) project: Associated factors to prevalence and incidence of SARS-CoV-2 infection in educational settings during the 2020-2021 academic year

The Sentinel Schools project was designed to monitor and evaluate the epidemiology of COVID-19 in Catalonia, gathering evidence for health and education policies to inform the development of health protocols and public health interventions to control of SARS-CoV-2 infection in schools. The aim of this study was to estimate the prevalence and incidence of SARS-CoV-2 infections and to identify their determinants among students and staff during February to June in the academic year 2020-2021. We performed two complementary studies, a cross-sectional and a longitudinal component, using a questionnaire to collect nominal data and testing for SARS-CoV-2 detection. We describe the results and perform a univariate and multivariate analysis. The initial crude seroprevalence was 14.8% (95% CI: 13.1-16.5) and 22% (95% CI: 18.3-25.8) for students and staff respectively, and the active infection prevalence was 0.7% (95% CI: 0.3-1) and 1.1% (95% CI: 0.1-2). The overall incidence for persons at risk was 2.73 per 100 person-month and 2.89 and 2.34 per 100 person-month for students and staff, respectively. Socioeconomic, self-reported knowledge, risk perceptions and contact pattern variables were positively associated with the outcome while sanitary measure compliance was negatively associated, the same significance trend was observed in multivariate analysis. In the longitudinal component, epidemiological close contact with SARS-CoV-2 infection was a risk factor for SARS-CoV-2 infection while the highest socioeconomic status level was protective as was compliance with sanitary measures. The small number of active cases detected in these schools suggests a low transmission among children in school and the efficacy of public health measures implemented, at least in the epidemiological scenario of the study period. The major contribution of this study was to provide results and evidence that help analyze the transmission dynamic of SARS-CoV-2 and evaluate the associations between sanitary protocols implemented, and measures to avoid SARS-CoV-2 spread in schools.

Family Health among Families with Primary School Children during the COVID Pandemic in Thailand, 2022

Despite evidence suggesting that the COVID pandemic has negatively affected the mental health and well-being of school aged children and parents, there are limited studies describing the state of family well-being. This study aimed to use the family health lens to assess the well-being of Thai families with primary school children and to identify its associated factors. A cross-sectional survey was conducted during January and March 2022, a period of school closure when onsite education was replaced by online education from time to time. The family health scale (FHS) questionnaire survey was carried out among 701 parents of Thai families with primary school children. The questionnaire comprised 10 questions regarding family belief, health, relationships, financial security, and housing environment. Independent variables included: (1) parental/household factors; (2) online learning related issues; (3) children's mental health; and (4) parents' health behaviors. Multinomial logistic regression was undertaken. Results showed that half of Thai families (54.6%) reported having moderate health status. Factors that were associated with lower levels of family health, such as poor or moderate levels, included families with a child that had mental health problems (adjusted odd ratio (AOR) = 5.0 [95% CI = 2.6-9.5] for poor v. excellent, and AOR = 2.7 [95% CI = 1.9-4.0] for moderate v. excellent), single parents (AOR = 2.5 [95% CI = 1.2-5.2] for poor v. excellent), a higher number (≥3) of children (AOR = 2.1 [95% CI = 1.0-4.0] for moderate v. excellent), and smoking parents (AOR = 6.5 [95% CI =1.2-34.8] for poor v. excellent). During health emergencies, health policy for providing adequate assistance to single parents, especially those that have a child with mental health problems, is of utmost importance. The design of health promotion activities and interventions should be targeted not only at single families, but also families with higher numbers of children and parents who smoke at home.

A cross-sectional national investigation of COVID-19 outbreaks in nurseries during rapid spread of the Alpha (B.1.1.7) variant of SARS-CoV-2 in England

Background

In England, the emergence the more transmissible SARS-CoV-2 variant Alpha (B.1.1.7) led to a third national lockdown from December 2020, including restricted attendance at schools. Nurseries, however, remained fully open. COVID-19 outbreaks (≥ 2 laboratory-confirmed cases within 14 days) in nurseries were investigated to assess the risk of SARS-CoV-2 infection and cumulative incidence in staff and children over a three-month period when community SARS-CoV-2 infections rates were high and the Alpha variant was spreading rapidly across England.

Methods

This was a cross-sectional national investigation of COVID-19 outbreaks in nurseries across England. Nurseries reporting a COVID-19 outbreak to PHE between November 2020 and January 2021 were requested to complete a questionnaire about their outbreak.

Results

Three hundred and twenty-four nurseries, comprising 1% (324/32,852) of nurseries in England, reported a COVID-19 outbreak. Of the 315 (97%) nurseries contacted, 173 (55%) reported 1,657 SARS-CoV-2 cases, including 510 (31%) children and 1,147 (69%) staff. A child was the index case in 45 outbreaks (26%) and staff in 125 (72%) outbreaks. Overall, children had an incidence rate of 3.50% (95%CI, 3.21–3.81%) and was similar irrespective of whether the index case was a child (3.55%; 95%CI, 3.01–4.19%) or staff (3.44%; 95%CI, 3.10–3.82%). Among staff, cumulative incidence was lower if the index case was a child (26.28%; 95%CI, 23.54–29.21%%) compared to a staff member (32.98%; 95%CI, 31.19–34.82%), with the highest cumulative incidence when the index case was also a staff member (37.52%; 95%CI, 35.39–39.70%). Compared to November 2020, outbreak sizes and cumulative incidence was higher in January 2021, when the Alpha variant predominated. Nationally, SARS-CoV-2 infection rates in < 5 year-olds remained low and followed trends in older age-groups, increasing during December 2020 and declining thereafter.

Conclusions

In this cross-sectional study of COVID-19 outbreaks in nurseries, one in three staff were affected compared to one in thirty children. There was some evidence of increased transmissibility and higher cumulative incidence associated with the Alpha variant, highlighting the importance of maintaining a low level of community infections.

How did lockdown and social distancing policies change the eating habits of diabetic patients during the COVID-19 pandemic? A systematic review

Background

After the declaration of the COVID-19 pandemic, governments established national lockdowns and social distancing as an effective plan to control this disease. As a result of the lockdown policies, diabetic patients` access to food products, medication, and routine follow-ups is disrupted, making it difficult for them to control their disease.

Methods

International databases, including PubMed/Medline, Web of Science, and Scopus, were searched until April 2022. All observational studies included assessing the impact of lockdown and social distancing on eating habits (as primary outcome), and glycemic and anthropometric indices (as secondary outcomes) of diabetic patients during the COVID-19 pandemic. The Newcastle-Ottawa Quality Scale was used to assess the quality rating of the studies.

Results

Overall, 22 studies were included in this systematic review, the results of which varied in different communities. In most studies, consumption of grains, fruits, and vegetables was reported to increase. On the other hand, consumption of snacks and sweets was reported to increase in other surveys. During the COVID-19 lockdown, most diabetic patients preferred to cook meals at home, using less takeout, fast foods, and alcoholic drinks. Although the patients mostly improved their eating habits, the glycemic and anthropometric indices were contradictory in different studies. Studies showed that the eating habits of diabetic patients vary from country to country, even in some cases and studies done in the same country showed different results. For example, all the studies done in Japan showed an increase in the consumption of snacks and sweets, leading to weight gain in the patients. However, conflicting results in eating habits have been observed in studies conducted in India.

Conclusion

The lockdown policies have led to a beneficial change in the eating habits of diabetic patients to consume more fruits and vegetables and reduce the consumption of animal protein products and alcoholic beverages. While some diabetic patients have increased consumption of snacks and sweets, leading to a disturbance in their glycemic and anthropometric indices control. Understanding the consequences of lockdown and social distancing of the diabetic patient during the COVID-19 pandemic can help public health authorities make better recommendations to improve glycemic control.

Children's anxiety and parenting self-efficacy during the COVID-19-related home confinement

BACKGROUND

The COVID-19 crisis influenced the lives of families and preschoolers, worldwide. School closures and restriction measures introduced distance learning for preschoolers and remote working for parents. Social distancing narrowed opportunities to meet with peers and enjoy leisure activities. Additionally, social and mental services closures limited young children's accessibility to mental, speech and occupational health services. The aim of the current study was to investigate how home confinement during the third wave of the COVID-19 pandemic affected parenting self-efficacy and preschoolers' anxiety.

METHOD

An online survey based on a convenience sample took place on April 2021 to evaluate how home confinement to halt the third wave of COVID-19 pandemic influenced children's anxiety and parenting self-efficacy (PSE). Parents of 146 children (65 girls [44.5%] and 81 boys [55.5%]; aged 2-6 years old) were enrolled and completed a demographics form, the Preschool Anxiety Scale (PAS) and the Tool to Measure Parenting Self-efficacy (TOPSE).

RESULTS

Most of the participants reported that the relationship with their child was positively affected from staying at home. TOPSE mean scores reflected average parenting self-efficacy. PSE was negatively correlated with children's anxiety. COVID-19-related variables 'Parent's vaccine hesitancy' and 'Death of a loved one' had a clear effect on preschoolers' anxiety, whereas the latter also on PSE.

CONCLUSION

Findings highlight the necessity of implementing public health strategies to strengthen families and support parents and their children during the ongoing health crisis.

Impact of COVID-19 Pandemic on School-Aged Children's Physical Activity, Screen Time, and Sleep in Hong Kong: A Cross-Sectional Repeated Measures Study

Despite concerns about the negative effects of social distancing and prolonged school closures on children's lifestyle and physical activity (PA) during the COVID-19 pandemic, robust evidence is lacking on the impact of the pandemic-related school closures and social distancing on children's wellbeing and daily life. This study aimed to examine changes in the PA levels, sleep patterns, and screen time of school-aged children during the different phases of the COVID-19 outbreak in Hong Kong using a repeated cross-sectional design. School students (grades 1 to 12) were asked to report their daily electronic device usage and to fill in a sleep diary, recording their daily sleep onset and wake-up time. They were equipped with a PA monitor, Actigraph wGT3X-BT, to obtain objective data on their PA levels and sleep patterns. Students were recruited before the pandemic (September 2019-January 2020; n = 577), during school closures (March 2020-April 2020; n = 146), and after schools partially reopened (October 2020-July 2021; n = 227). Our results indicated lower PA levels, longer sleep duration, and longer screen time among participants recruited during school closures than those recruited before the COVID-19 outbreak. Primary school students were found to sleep on average for an extra hour during school closures. The later sleep onset and increased screen time documented during school closures persisted when schools partially reopened. Our findings illustrate the significant impact of social distancing policies during the COVID-19 pandemic on the sleep pattern, screen time, and PA level in school-aged children in Hong Kong. Professionals should urgently reinforce the importance of improving physically activity, good sleep hygiene, and regulated use of electronic devices for parents and school-aged children during this unprecedented time.

Changes in life satisfaction, depression, general health and sleep quality of Spanish older women during COVID-19 lockdown and their relationship with lifestyle: an observational follow-up study

OBJETIVES

To analyse the effects of COVID-19 lockdown on mental well-being variables of older women, and to determine the influence of lifestyle and age on such effects. The hypothesis of the study was that all parameters related to mental well-being would worsen in older women during the COVID-19 lockdown.

DESIGN

Observational follow-up study. Pre lockdown measurements were taken before the lockdown. Post lockdown measurements were taken as soon as began the de-escalation.

SETTING

Senior centres in the Region of Murcia (Spain).

PARTICIPANTS

The sample was composed of 40 older women volunteers, over 54 years of age (mean age=62.35±8.15 years).

PRIMARY AND SECONDARY OUTCOME MEASURES

Pre lockdown and post lockdown evaluations were carried out face to face. The following questionnaires were completed: Satisfaction with Life Scale, The Center for Epidemiologic Studies Depression Scale, The Short Form 36 Health Survey, The Pittsburgh Sleep Quality Index, the Global Physical Activity Questionnaire and Prevention with Mediterranean Diet.

RESULTS

Post lockdown, a worsening was found in the variables of life satisfaction (p=0.001); depression (p<0.001), quality of life in physical role (p=0.006), pain (p=0.004), emotional role (p<0.001) and mental health (p<0.001); and sleep quality (p=0.018), sleep latency (p=0.004), sleep disturbances (p=0.002) and global sleep quality score (p=0.002). It was found how age influenced the variables of pain (p=0.003) and social role (p=0.047), as well as the influence of a healthy lifestyle on the variables analysed (F=6.214; p=0.017). Adherence to the Mediterranean diet was shown to be a protective factor against increased depression (p=0.03). Spending time sitting was shown to be a risk factor for physical role health (p=0.002), as was advanced age on health due to worsening pain (p=0.005), or an unhealthy lifestyle on increased consumption of sleeping aids (p=0.017).

CONCLUSION

The lockdown had a great negative impact on Spanish older women on mental well-being variables.

Psychosocial Wellbeing of Schoolchildren during the COVID-19 Pandemic in Berlin, Germany, June 2020 to March 2021

The COVID-19 pandemic and related restrictions have affected the wellbeing of schoolchildren worldwide, but the extent and duration of specific problems are still not completely understood. We aimed to describe students’ psychosocial and behavioral parameters and associated factors during the COVID-19 pandemic in Berlin, Germany. Our longitudinal study included 384 students from 24 randomly selected Berlin primary and secondary schools, assessing psychosocial wellbeing at four time points between June 2020 and March 2021. We analyzed temporal changes in the proportions of anxiety, fear of infection, reduced health-related quality of life (HRQoL), physical activity and social contacts, as well as sociodemographic and economic factors associated with anxiety, fear of infection and HRQoL. During the observation period, the presence of anxiety symptoms increased from 26.2% (96/367) to 34.6% (62/179), and fear of infection from 28.6% (108/377) to 40.6% (73/180). The proportion of children with limited social contacts (<1/week) increased from 16.4% (61/373) to 23.5% (42/179). Low physical activity (<3 times sports/week) was consistent over time. Low HRQoL was observed among 44% (77/174) of children. Factors associated with anxiety were female sex, increasing age, secondary school attendance, lower household income, and the presence of adults with anxiety symptoms in the student´s household. Fear of infection and low HRQoL were associated with anxiety. A substantial proportion of schoolchildren experienced unfavorable psychosocial conditions during the COVID-19 pandemic in 2020/2021. Students from households with limited social and financial resilience require special attention.

Changes in Physical Health-Related Indexes of Chinese College Students before and after COVID-19 Lockdown

The outbreak of the COVID-19 pandemic has caused negative impacts on people's lifestyles, as well as considerable indirect social impacts, which has even overshadowed the direct impact of virus infection itself. This study is aimed at examining the changes in physical health-related indexes of Chinese college students before and after the COVID-19 lockdown. The data of this study are from the National Physical Health Testing Program, covering 43 college students (male: 22) from a class of a Chinese university. Paired t-tests were performed on the physical health test data separately collected in November 2019 before the COVID-19 pandemic and October 2020 after the COVID-19 lockdown was lifted. As shown by the test results, compared to the prelockdown data, college students had an increased body mass index (BMI) (0.43 (SD 0.94) P = 0.004), decreased vital capacity (VC) (-128.98 (SD 310.13) ml P = 0.009), and lowered performance in the 800/1000 m endurance (-6.21 (SD 8.81) points P < 0.001) and standing long jump tests (-2.44 (SD 7.37) points P = 0.036) after the lockdown, and the differences in these regards all were significant. In addition, for the students in the overweight/obese group, their pre- and postlockdown physical fitness test results were found to have no statistically significant difference (P > 0.05), but the students in the control group showed a significantly increased BMI, as well as significantly decreased vital capacity and performance in the 800/1000 m endurance and standing long jump tests (P < 0.05). The findings of this study are expected to help government departments and policymakers better understand the impacts of school closures and online learning on the physical health of adolescents, while providing a basis for the formulation of measures that are aimed at reversing adolescents' physical health decline.
