This study to examine associations between cardiorespiratory fitness (CRF), 24-hour movement components, and cardiometabolic risk factors in children from southern Brazil, emphasizing the critical variables in these relationships. The sample included 186 schoolchildren (6–11 years, 8.57±1.56). Waist circumference (WC) and CRF were assessed using PROESP-Br protocols, while physical activity (moderate to vigorous–MVPA, and light–LPA) was measured via accelerometers. Sleep and screen time were reported by parents, and fasting blood samples provided data on triglycerides, HDL cholesterol, glucose, insulin, and HOMA-IR. Network analysis highlight WC, systolic blood pressure, and MVPA as central variables with significant connectivity. MVPA emerged as central among 24-hour movement behaviors, with CRF playing an intermediary role. Results underscore WC and MVPA’s relationship on cardiometabolic health, supporting interventions targeting MVPA to prevent early cardiometabolic risks in children.
