Ke D, Lu D, Cai G, et al. - In this cross-sectional study, researchers sought to explore the connection between accelerated skeletal maturation, defined as relative skeletal age (SA minus chronological age [CA]) ≥1.0 years, and overweight/obesity in preschool Chinese children. The sample consisted of 1,330 candidates aged 3.1–6.6 years old (730 males and 600 females) in Shanghai, China. According to the method of TW3-C RUS, the skeletal age was determined. According to results, an association was found between accelerated skeletal maturation and overweight/obesity among preschool children. This study demonstrates that accelerated skeletal maturation in preschool children could coexist with overweight/obesity, and interventions like dietary modifications and increasing levels of physical activity should be used to prevent both accelerated skeletal maturation and overweight/obesity as early as preschool age.
