Identification of preschool children's physical fitness phenotypes and their association with multidimensional body shape indicators
Objective: Traditional physical fitness assessments in young children often rely on single indicators, which fail to capture integrated ability patterns. The common use of body mass index (BMI) to link morphology and fitness has limited discriminant validity. This study aimed to identify naturally emerging physical fitness profiles among preschool children in Macao using a data-driven approach and to develop a screening tool based on multi-dimens…

Influence of Family Environment on the Scientific Fitness Literacy of Preschool and School Children in China
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 low…

Compliance with Health-Related Behaviors Guidelines and Its Relationship with Multiple Factors in Preschool Children Aged 3–6 Years
Different types of family environments were associated with the different levels of MVPA, ST and SLP among Chinese preschool children. In addition to the influence of parents' education and family income, parents could also improve their children's behaviors by providing a supportive family environment. The more of these factors presented in a family, the more likely it was for children to meet the guidelines. Therefore, for those families whose …
Population mental health matters child health disparity
Although the U5MR converges across countries, the reason varies. The PMH gradient in child mortality is mainly explained by the change in the return to risk factors. The PMH-gradient health disparity in boys is larger than that in girls in 2019, which indicates that boys' health may be more vulnerable to the development of PMH recently. The findings remind us that we need to pay attention to the hidden reasons for the growth of disparity. It also…
