Change in Japanese children’s 24-hour movement guidelines and mental health during the COVID-19 pandemic

Specialized guidelines are required for the health behaviors of vulnerable populations such as children. This is especially true during the COVID-19 pandemic, wherein major lifestyle changes have occurred, especially among young children. The present study aims to use longitudinal data to understand changes in the physical activity, screen time, sleep, and mental health of preschoolers in Japan during the COVID-19 pandemic, compared to pre-pandemic period. Subjective and objective measures were used to assess the variables of interest longitudinally. It was found that physical activity, adherence to WHO-recommended screen time, and prosocial behaviors decreased significantly. On the other hand, sedentary time and hyperactivity increased. Our results are consistent with findings from other countries. The implications with respect to outdoor playtime, screen-time in the context of online learning during the pandemic, and the effects of parents’ mental health on preschool-aged children are discussed.

Associations among Outdoor Playtime, Screen Time, and Environmental Factors in Japanese Preschoolers: The ‘Eat, Be Active, and Sleep Well’ Study

This cross-sectional study investigated regional differences in outdoor playtime and screen time among preschool-age children in Japan, and their associations with environmental factors, in order to identify the modifiable determinants of the differences between urban and rural areas. Data were obtained from the “Eat, be active, and sleep well” study. Children from three (n = 872) and five (n = 744) kindergartens in urban and rural regions of Japan, respectively, who completed a questionnaire survey, were sampled. Finally, data from 1128 participants (age: 3–5 years) were analyzed. To assess the environmental factors, the International Physical Activity Questionnaire was used for neighborhood environments; the Global Physical Activity Questionnaire was used for physical home environments; and a three-item questionnaire was used for sociocultural environments. Outdoor activity was significantly associated with items related to the mother’s sedentary time and the number of siblings/friends in both urban and rural regions. Screen time was associated with the mother’s screen time, television in the room, and esthetic qualities, which were consistent between urban and rural regions, while screen time was associated with night-time crime rates and traffic in the urban region. Our study further bolsters evidence suggesting that outdoor playtime and screen time are strongly associated with various environmental factors among Japanese preschool-age children.

Changes in Physical Activity, Screen Time, Sleep, and Mental Health of Japanese Young Children: A Longitudinal Study Pre- and During-COVID-19

Time Regulation as Institutional Condition for Children’s Outdoor Play and Cultural Formation in Kindergarten

Time regulation is an important aspect of the everyday life in any kindergarten and has an impact on which activities are given priority. In this case study, the outdoor playtime in one kindergarten in China and one in Norway is compared based on the understanding that children’s cultural formation develops in a dialectical relationship between children’s interests and motives and societal, institutional, and weather conditions. The aim of the article is to identify how time regulations provide conditions for children’s play and cultural formation during outdoor playtime. The research question is: How does institutional time regulation interplay with the pedagogical practice and children’s activities in the outdoor playtime? Employing a cultural-historical approach, drawing on Hedegaard’s concepts of development and cultural formation as an individual, institutional and societal process, the dialectical interplay between institutional time regulation and children’s engagement in outdoor activities is the unit of analysis in this study. Our findings indicate that the kindergarten teachers in the Chinese kindergarten as well as the Norwegian kindergarten aim to adjust the pedagogical content and time schedule to the traditions, values, and conditions in both countries. This chapter contributes to knowledge about the interplay between institutional conditions and children’s activities and cultural formation in outdoor play.

Children’s Play and Social Relations in Nature and Kindergarten Playgrounds: Examples from Norway

In kindergarten, outdoor playtime is usually a break from more structured activities. It is leisure time and an opportunity for children to engage in free play with friends. Previous research indicates that time spent outdoors facilitates playful physical activity and that playing in nature inspires children’s creativity, imaginations and play across age and gender. In short, play and social relations are crucial for young children’s development and cultural formation. This study investigated children’s play activities during outdoor playtime in nature and on kindergarten playgrounds. Its empirical materials consisted of video observations of 12 four-year-old’s activities in nature and on a kindergarten playground and interviews with two kindergarten teachers. One child, Benjamin was the primary focus, and five more were also included. Two examples of one child’s social play in nature and on the playground were analysed to illuminate the different conditions and challenges he encountered. The findings indicate that children’s play in nature tends to be more creative and inclusive than that on kindergarten playgrounds, that kindergarten teachers participate more in children’s play in nature than on playgrounds and that children are sensitive to and try to engage in what they view as a correct form of discourse with their teachers. The author argues for further research on the subject to learn more about children’s social relations, creativity and cultural formation during outdoor playtime in nature.

Physical Activity and Sedentary Behaviors of Children in Family Child Care Homes: Are There Opportunities for Improvement?

Purpose: Many children attend family child care homes (FCCHs), an important setting to influence children’s physical activity (PA) and sedentary behavior (SB). This study assessed children’s PA and SB while in FCCHs, characteristics of the FCCH PA environment, and relationships between the environment and child PA and SB. Method: Children ages 1.5–4.0 years (n = 495) were recruited from 165 FCCHs in North Carolina. Children’s moderate to vigorous PA and SB were measured via accelerometry for 3 days. FCCH PA environments were assessed over 2 days using the Environment and Policy Assessment and Observation for FCCHs. Ten subscores and an overall PA environment score (possible range: 0–30) were calculated; higher scores indicate better quality. Results: Children accumulated 30 (13) minutes of moderate to vigorous PA and 143 (42) minutes of SB in FCCHs daily. FCCHs scored low on the Environment and Policy Assessment and Observation for FCCHs, with an average overall score of 13 (2). FCCHs scored highest on screen time and screen time practices subscores, and lowest on PA education/professional development and PA policy subscores. Although no statistically significant associations were observed, some large Cohen d effect sizes were noted (eg, outdoor playtime subscore and moderate to vigorous PA). Conclusions: This study highlights opportunities to improve FCCHs and increase children’s behaviors (eg, providing adequate time and outdoor play spaces).

Physical and Sedentary Activity Levels Among Preschoolers in Home-Based Childcare: A Systematic Review

Background:Although preschoolers’ physical activity in center-based childcare has received considerable attention, less is known regarding this group’s activity levels within home-based childcare. This review aimed to explore and synthesize the literature on preschoolers’ physical and sedentary activity levels in home-based childcare. Outdoor playtime was also examined to contribute to the understanding of preschoolers’ activity levels within this particular setting.Methods:Nine online databases were searched for peer-reviewed, English-language, primary studies that quantitatively measured physical and sedentary activity levels of preschoolers attending home-based childcare. Studies were excluded if they were nonprimary research, if they lacked a preschool-aged sample, if they did not quantitatively measure physical or sedentary activity, or if they took place in an ineligible environment.Results:Seven articles were included in this review; 3 had objective measures of activity levels, and 4 relied on nonobjective measures. Accelerometry data suggest that preschoolers’ average sedentary, moderate-to-vigorous, and total physical activity levels in home-based childcare ranged from 39.5 to 49.6, 1.8 to 9.7, and 10.4 to 33.8 min/hr, respectively. Outdoor playtime appears to be inconsistent in home-based childcare.Conclusion:Physical activity among preschoolers attending home-based childcare appears to be relatively low and widely varied. Sedentary time has received less attention in home-based childcare settings. Future research examining activity levels in this unique environment is warranted.
