Association of nutrition education and exercise with cardiometabolic health risk factors among overweight and obese adolescents: an odds ratio analysis

Objective To explore the association of nutrition education and exercise with cardiometabolic health risk factors among overweight and obese adolescents. Methods This quasi-experimental study utilised a pretest-posttest design to evaluate changes in body mass index (BMI), blood pressure, and fasting biochemical markers [(glucose, insulin, high-density lipoprotein cholesterol (HDL-C); low-density lipoprotein cholesterol (LDL-C); triglycerides, glycated haemoglobin (HbA1c); homeostatic model assessment of insulin resistance (HOMA-IR)] among 41 participants. The intervention combined supervised aerobic and resistance exercise sessions thrice weekly with a weekly nutrition education session over 10 weeks. The Statistical Package for the Social Sciences was used for data analysis, with p<0.05 indicating statistical significance. Results Post-intervention, males had lower triglyceride (p=0.045) and LDL-C concentrations (p=0.043). In female adolescents, the intervention reduced diastolic blood pressure (p=0.045), LDL-C (p=0.012), insulin (p<0.001), and HOMA-IR concentrations (p=0.001). The intervention was a significant predictor of reduced LDL-C (p=0.003), HOMA-IR (p=0.010), blood glucose concentrations (p=0.020), and HbA1c levels (p=0.011). Conclusions The improvements in CMD risk factors suggest potential long-term benefits supporting the usefulness of such an intervention. However, divergent sex-specific responses to the intervention underscore the importance of developing sex-specific intervention programs.
