Background: Overweight and obesity during childhood consist two of the most important public health issues in the 21st century. Consumption of high-fat processed food has been increased alarmingly. Objective: To examine the association between parental ultra-processed, high-fat products' consumption and childhood overweight/obesity. Methods: A cross-sectional survey, conducted among 422 children, aged 10-12 years, and their parents, during school years 2014-16. Parental and child data were collected through self-Administered, anonymous and validated questionnaires. Among others, high-fat ultra-processed food consumption was also recorded. Children's weight status was based on gender-and age-specific tables derived from the International Obesity Task Force body mass index (BMI) cut-offs. Results: The prevalence of obesity in the reference population was 2.9%, whereas the prevalence of overweight was 19.3%. A strong correlation was observed between children's and their parents' BMI status (P < 0.001). Multi-Adjusted data analysis revealed no association between parental intake of ultra-processed, high-fat products and children overweight/obesity. Similarly, when the data analysis accounted for family income and physical activity status of the children, the aforementioned results remained insignificant. Conclusion: Despite the fact that parents' specific dietary habits seem not to affect their children's weight status, public health programs should consider parental nutrition education and mobilization as a preventive measure for childhood overweight/obesity.
