  • Association Between the COVID-19 Pandemic and Early Childhood Development

    Sato Koryu, Fukai Taiyo, Fujisawa Keiko K., Nakamuro Makiko

    [Importance] Although a growing number of studies have reported negative associations of the COVID-19 pandemic with academic performance among school-aged children, less is known about the pandemic’s association with early childhood development. [Objective] To examine the association between the COVID-19 pandemic and early childhood development. [Design, Setting, and Participants] In this cohort study conducted in all accredited nursery centers in a Japanese municipality, baseline surveys of children aged 1 and 3 years (1000 and 922, respectively) were conducted between 2017 and 2019, and participants were followed up for 2 years. [Exposure] Children’s development was compared at age 3 or 5 years between cohorts that were exposed to the pandemic during the follow-up and a cohort that was not. [Main Outcome and Measure] Children’s developmental age was measured by nursery teachers using the Kinder Infant Development Scale (KIDS). Data were analyzed between December 8, 2022, and May 6, 2023. [Results] A total of 447 children (201 girls [45.0%] and 246 boys [55.0%]) aged 1 year at baseline were followed up to age 3 years, and 440 children (200 girls [45.5%] and 240 boys [54.5%]) aged 3 years at baseline were followed up to age 5 years. During the follow-up, the cohorts that were exposed to the pandemic were 4.39 months behind in development at age 5 compared with the cohort that was not (coefficient, −4.39; 95% credible interval, −7.66 to −1.27). Such a negative association was not observed in development at age 3 years (coefficient, 1.32; 95% credible interval, −0.44 to 3.01). Variations in development were greater during the pandemic than before the pandemic regardless of age. Additionally, the quality of care at nursery centers was positively associated with development at age 3 years during the pandemic (coefficient, 2.01; 95% credible interval, 0.58-3.44), while parental depression appeared to amplify the association between the pandemic and delayed development at age 5 (coefficient of interaction, −2.62; 95% credible interval, −4.80 to −0.49; P = .009). [Conclusions and Relevance] The findings of this study showed an association between exposure to the pandemic and delayed childhood development at age 5 years. Variations in development widened during the pandemic regardless of age. It is important to identify children with developmental delays associated with the pandemic and provide them with support for learning, socialization, physical and mental health, and family support.

  • Quality of early childhood education and care in Japanese accredited nursery centers: A study using the Early Childhood Environment Rating Scale, Third Edition (ECERS-3)

    　View Summary

    This study presents the first quantitative evaluation of the quality of early childhood education and care (ECEC) in Japan to make a significant contribution to the body of knowledge accumulated on ECEC in countries where research has been limited. We observed 30 classes comprising 3-year-olds, 28 classes comprising 5-year-olds, and 30 classes comprising mixed-ages from publicly provided nursery centers under the jurisdiction of the Kanto metropolitan area, Japan. An internationally-recognized quality rating scale for ECEC called the Early Childhood Environment Rating Scale, 3rd edition, which consists of six subscales, was used for this study. In contrast to previous studies conducted in the US, the results of this study showed that the Japanese ECEC is characterized as showing higher scores in the two subscales, “Personal Care Routines” and “Interaction,” and showing lower score in the subscale, “Learning Activities.” In addition, this study showed that the quality of ECEC varied across nursery centers. Furthermore, with regard to the two subscales, “Interaction” and “Language and Literacy,” the degree of variation within centers differed across nursery centers. This study analyzed how these characteristics of Japanese ECEC can be partly produced by the existence of national guideline for nursery centers authorized by the Japanese government. In addition, mechanisms producing differences in the quality of ECEC among and within centers were also discussed.

  • An Association between Poverty, Health and Developmental Risks during Early Childhood with Subsequent Academic Performance

    Fujisawa Keiko K., Fukai Taiyo, Hiroi Noriko, Nakamuro Makiko

    　View Summary

    <p>Using a large scale of administrative records provided by a local government, this study showed that experiencing family financial difficulties before school entry, signaled by receiving public assistance, and a child's own risk on health/development evaluated at the time of the Health Checkup for 3-year-old children lowered academic performance. It was deduced that the negative association between past financial difficulties of families and academic performance was greater than that between children's health and developmental risks and academic performance. Furthermore, the longer the period of exposure to family financial difficulties is, the greater the impact is. Additionally, the absence of health checkups for 3-year-old children was negatively related to academic performance. It was discussed that information on administrative records related to the welfare, health, and education of all children aggregated across jurisdictions and clarifying the relationship between developmental risk factors and outcomes would be extremely important for the effective implementation of scientifically based outreach and push-type support.</p>
