Abstract: This study focuses on childhood obesity among preschool children. Through a literature review methodology, we systematically synthesize existing research. Globally and in China, the prevalence of overweight and obesity in preschool children has been rising, posing a significant public health challenge. The etiology of this condition is multifactorial, involving dietary habits, genetic predisposition, physical activity levels, sleep patterns, and other interrelated determinants. Guided by the evidence-based three-tiered prevention framework (primary, secondary, and tertiary prevention), this paper proposes interventions encompassing dietary management, exercise programs, and health education, while emphasizing the critical role of multi-sectoral collaboration. Future research should prioritize cross-cultural comparative studies and longitudinal tracking of intervention effectiveness, aiming to inform policy development and practical implementation in this field.
