Influence of Family Environment on the Scientific Fitness Literacy of Preschool and School Children in China: A National Cross-Sectional Study

Scientific fitness literacy (SFL) is a holistic concept based on physical literacy but has a smaller scope and is more specific to exercise and scientific fitness. We developed an instrument to assess SFL and explored the differences and similarities in the effects of the home environment on children’s SFL. Data from a nationwide stratified random sample of children were analyzed using multiple linear regression. SFL scores were significantly lower for preschoolers than for school-age children. The family environment has an impact throughout the preschool and school years, with school-age children’s SFL being less influenced by family members than preschool children; screen time has a negative impact on their SFL but reducing the number of electronic devices and increasing parental physical activity and modeling can alleviate its impact. The economic status of the family is crucial, with sports consumption expenditure and household sports equipment ownership being favourable factors for children’s SFL. Positive parental attitudes and sporting habits have a positive impact on their children’s SFL. The findings of this study can be used to improve children’s SFL in the home environment and to take effective measures to avoid the risk factors.
