CHANGES IN CHILDREN'S PHYSICAL DEVELOPMENT IN THE MODERN WORLD

This study analyzes modern trends in the physical development of preschool-aged children (3–6 years) and the influence of environmental, nutritional, socio-economic, and technological factors. Based on a systematic review of recent physiological, pediatric, and epidemiological literature spanning 2009–2024, findings indicate significant shifts in anthropometric and functional parameters compared to previous decades. The prevalence of overweight has nearly quadrupled since the 1980s, while physical fitness scores have declined by an estimated 10–15% in urban populations. These trends highlight the critical role of lifestyle transformation, sedentary behavior, and environmental stressors in disrupting normal growth trajectories.
