WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: Spinal curvature abnormalities have emerged as a major public health challenge for children and adolescents in China, with detection rates showing a concerning upward trend in recent years. WHAT IS ADDED BY THIS REPORT?: This population-based surveillance study revealed a 2.1% detection rate of abnormal spinal curvature among children and adolescents aged 6-17 years in Jiangsu Province. The findings emphasize the critical need for early intervention programs targeting modifiable risk factors, including insufficient physical activity, inadequate sleep duration, and improper reading and writing posture. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: The increasing burden of abnormal spinal curvature requires targeted attention, particularly for high school students and females during growth spurts. A comprehensive approach combining early lifestyle interventions, such as adequate outdoor activities, with appropriate referrals to public health specialists and orthopedic surgeons may enhance risk mitigation. Success in addressing this challenge requires coordinated multisectoral collaboration and active parental engagement.
