Objective: Obesity is a common epidemic issue in all over the world. In order to prevent obesity it is essential to know about obesity and its detrimental consequences. This study aimed to evaluate children's awareness about obesity and to determine the associations between level of awareness, healthy lifestyle, dietary habits and risk factors for metabolic syndrome. Methods: Two hundred and thirty-six overweight children (119 boys and 117 girls) aged 10-14 years were enrolled to the study. Anthropometric and biochemical measurements were taken and metabolic syndrome (MetS) definition were done according to the International Diabetes Federation (IDF) consensus and divided into two groups as MetS (+) and MetS (-). Obesity awareness scale (OBA) and Adapted Healthy Lifestyle-Diet Index for Turkey (HLD-TR) were performed. Results: Among children, the prevalence of having MetS was found as 26.3%. Obesity awareness and HLD-TR index sores were lower in MetS (+) group than MetS (-) group. Metabolic syndrome related biochemical parameters and anthropometric measurements were associated with obesity awareness level of the children. The binary logistic regression model shows that a one-unit increase in the OBA index score increases the odd of not having MetS for 1.12 times after adjustments for age, gender, body mass index, and HLD-TR index score. Conclusions: Increased awareness about obesity among children will help to reduce the risk of metabolic syndrome, type 2 diabetes and atherosclerotic cardiovascular diseases in the future.
