Insights
Physical development in Moscow preschoolers is concerning, with many exhibiting deviations. Underdeveloped locomotor and respiratory systems are key issues, particularly affecting girls more than boys.
Area of Science:
- Pediatrics
- Child Development
- Public Health
Background:
- Childhood development is crucial for long-term health.
- Assessing physical development in early childhood is essential for identifying potential issues.
- Previous studies highlight varying developmental trajectories in children.
Purpose of the Study:
- To evaluate the physical development quotients of 5-6-year-old children in Moscow.
- To identify the prevalence of physical developmental deviations in this cohort.
- To analyze gender-specific differences in physical development.
Main Methods:
- Cross-sectional survey conducted in 2005.
- Assessment of development quotients in 5-6-year-old children.
- Analysis of physical developmental deviations, focusing on locomotor and respiratory systems.
Main Results:
- Only 41.9% of boys and 30.7% of girls showed no physical developmental deviations.
- Underdevelopment of the functional parameters of the locomotor apparatus and respiratory system were major identified problems.
- Girls exhibited significantly poorer physical development across most integral indices compared to boys.
Conclusions:
- A significant proportion of 5-6-year-old children in Moscow exhibit physical developmental deviations.
- Impaired locomotor and respiratory function represent critical areas of concern in childhood development.
- Targeted interventions may be necessary to address gender disparities in physical development.
Abstract:
The paper gives development quotients in 5-6-year-old children from the North-Western Administrative District of Moscow, which were obtained from the survey made in 2005. Only 41.9% of the boys and 30.7% of the girls were ascertained to have no physical developmental deviations. The major problem of childhood development is the underdevelopment of the functional parameters of the locomotor apparatus and respiratory system. The physical development is significantly worse in the girls than that in the boys in the majority of integral indices.

Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...
