This article seeks to review the current knowledge of the SARS-CoV-2 virus and the health effects for children and youth with special health care needs (CYSHCN). COVID-19, an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), became a major pandemic in 2020. Recognition of the disease could be difficult, as symptoms in children are at times different than adults and can mimic other common childhood viral infections. Children with underlying medical conditions did make up a higher proportion of those hospitalized, but also were affected in other ways including loss of nursing support, missed education and rehabilitative services, and increased stress for themselves and their families, affecting mental health in this vulnerable population. This review seeks to address what is currently known about the overall effects on CYSHCN and their families, and identify gaps in research, including the implementation of health care systems, and possible suggestions for change in the educational and community supports for this group of individuals. Ongoing analysis of large national and international data sets, as well as smaller reports based on specific congenital anomaly, genetics disease, and acquired childhood illness, and then attention to local resources and family resilience is still necessary.

The studies on the association between sleep duration and myopia are limited, and the evidence is inconsistent. This study aimed to evaluate the association between sleep duration and myopia, cycloplegic spherical equivalent (SE) and axial length (AL) among Chinese children during the Corona Virus Disease 2019 (COVID-19) pandemic. The study was a cross-sectional study on Chinese children aged 6–18 years. The comprehensive ophthalmic examinations for children included cycloplegic SE, AL, and standardized questionnaires. The questionnaire included sleep duration, parental myopia, outdoor time, and continuous near work duration without breaks. Myopia was defined as SE ≤-0.50 diopters (D).

This study aimed to investigate the effect of the coronavirus disease (COVID-19) pandemic on Korean adolescents' oral health and identify the influential factors. The raw data from The Korea Youth Risk Behaviour Web-based Survey before (2019) and after (2020) the outbreak of COVID-19 were used in the study. Demographic characteristics and subjective general, mental, and oral health were analysed and compared between the 2 years. Further, the impact of changes in subjective mental health and the duration of indoor activity on oral health were analysed. Data were analysed using IBM SPSS Statistics, and all statistical significance was set at α = 0.05. The analysis was performed using the complex sample analysis module.

COVID-19 continues to have severe repercussions on children and pregnant women. The repercussions include not only the direct impact of COVID-19 (ie, children getting infected by COVID-19) but also indirect impacts (eg, safeguarding from child maltreatment, obesogenic behaviors, language and socioemotional development, educational consequences [eg, interrupted learning]; social isolation; mental health; behavioral health [eg, increased substance use in adolescence]; health and economic impact of COVID-19 on caregivers and family relationships. It has also shed light on long-standing structural and socioeconomic issues, including equity in nutrition and food security, housing, childcare, and internet access. Using a socioecological, life course, and population health approach, this study discusses the implications for pregnant women and children’s health and well-being and give recommendations for mitigating the short and long-term deleterious impact COVID- 19 on women, children, and their families.

This research aimed to identify the research on childhood disability service adaptations and their impact on children and young people with long-term disability during the COVID-19 pandemic. A mapping review was undertaken. The World Health Organization Global COVID-19 database was searched using the search terms ‘children’, ‘chronic/disabling conditions’, and ‘services/therapies’. Eligible papers reported service changes for children (0–19 years) with long-term disability in any geographical or clinical setting between 1st January 2020 and 26th January 2022. Papers were charted across the effective practice and organization of care taxonomy of health system interventions and were narratively synthesized; an interactive map was produced.

This study aims to describe the impacts arising from the interference of the infection caused by COVID-19 in the woman's gestational process, considering the mother-child binomial and their fetal interaction. This is a systematic review according to the PRISMA protocol, based on Scielo, PubMed and LILACS, considering publications between January 2020 and June 2021. The descriptors pregnancy, COVID-19, newborn and maternal and child health were used. Articles were selected by reading the title, abstract and methodology.

The long-term sequela of COVID-19 on young people is still unknown. This systematic review explored the effect of COVID-19 on lung imaging and function, cardiorespiratory symptoms, fatigue, exercise capacity and functional capacity in children and adolescents ≥ 3 months after infection. A systemic search was completed in the electronic databases of PubMed, Web of Science and Ovid MEDLINE on 27 May 2022. Data on the proportion of participants who had long-term effects were collected, and one-group meta-analysis were used to estimate the pooled prevalence of the outcomes studied.

This paper aimed to estimate the effects of school closures and associated lifestyle changes on myopia in Chinese children and adolescents during the coronavirus disease 2019 (COVID-19) pandemic. Two cross-sectional surveys recruited 14,296 Chinese students aged 7 to 18 years in November 2019 and June 2020 from which an open cohort study (nested queue design) was derived and used to assess myopia prevalence, incidence, and progression rates (defined as students with progression in myopia severity at the second survey wave among those with myopia at baseline). The severity of myopia was determined by measurements of visual acuity (<5.0) and noncycloplegic refraction (spherical equivalent <−0.50 diopters). Twenty-three myopia-influencing factors were divided into three categories: eye-use habits, lifestyle, and family and subjective factors. Responses to each of these 23 factors were labeled as either positive or negative options and then combined to generate a comprehensive score.

Myopic shift had been observed during the COVID-19 lockdown in young school children. It remains unknown whether myopic shift is accompanied with increase in axial length. This study aimed to evaluate the impact of the COVID-19 lockdown on myopia and axial length of school children in China by comparing them before, during and after the lockdown. In this population-based cross-sectional study, school-based myopia screenings were conducted in the Fall of 2019, 2020, and 2021 (representing before, during and after COVID-19 lockdown respectively) in Chengdu, China. Myopia screenings were performed on 83,132 students aged 6 to 12 years. Non-cycloplegic refractive error was examined using NIDEK auto-refractor (ARK-510A; NIDEK Corp., Tokyo, Japan) and axial length was measured using AL-Scan (NIDEK Corp., Tokyo, Japan). Spherical equivalent (SER, calculated as sphere+ 0.5*cylinder), prevalence of myopia (SER ≤ -0.50 D), and axial length were compared across 3 years stratified by age.

This paper aimed to explore the experiences, information and support needs of parents/caregivers of children with cancer and how these changed as the COVID-19 pandemic evolved. Online surveys containing closed and free-text questions on experiences, information and support needs were completed at four time points (between April 2020 and October 2021) during the COVID-19 pandemic. Descriptive statistics of closed items and content analysis of qualitative data were conducted.

Little is known about the experience of receiving in-person and virtual clinical health care services during the COVID-19 pandemic for Canadian children with developmental disabilities and delays facing multiple layers of vulnerability (e.g., low income, low educational attainment families). It examined the relationship between socio-demographic factors and the receipt of these services (physical and mental health services) during COVID-19 for Canadian children with these conditions. Data collected in Canada for the Global Report on Developmental Delays, Disorders and Disabilities were used. The survey: (1) was developed and disseminated in collaboration with caregivers of children with disabilities, (2) included topics such as response to the pandemic and receipt of services and supports, and (3) documented the experiences of a non-random convenience sample of caregivers of children (any age) with these conditions during and prior to the pandemic.

The impact of the coronavirus disease 2019 (COVID-19) pandemic on dental caries is unknown. We investigated the effect of the pandemic on child dental caries in Japan by comparing the increase in dental caries from fourth to sixth grade between two cohorts, COVID-19 exposed cohort and COVID-19 unexposed cohort, using difference-in-differences analysis. Longitudinal data that followed elementary school children in Adachi City, Tokyo, were analyzed. The analysis consisted of two cohorts: those who were in fourth grade in 2016 and sixth grade in 2018 (COVID-19 unexposed cohort, N = 399) and those who were in fourth grade in 2018 and sixth grade in 2020 (COVID-19 exposed cohort, N = 3,082). Children’s dental caries were examined by school dentists.
