Intergenerational Eating Behaviors Beyond Genetics: Insights from Cognitive and Normative Influences

This study explores the intergenerational transmission of eating behaviors within Iranian families, emphasizing the role of Cognitive Social Theory (CST) and Value-Belief-Norm (VBN) Theory. By examining how parental eating habits influence the dietary choices of adult children, the research integrates cognitive, behavioral, and environmental factors. Utilizing a structured questionnaire and Structural Equation Modeling (SEM), data were collected from families with adult children aged 18–30 in Iran. The findings reveal significant associations between parental self-efficacy, outcome expectations, food knowledge, and children's eating behaviors. Observational learning and social support emerged as critical components in shaping dietary practices. The results highlight the necessity of addressing familial influences on nutrition in public health interventions, informing strategies aimed at promoting healthier eating patterns and reducing the prevalence of obesity and related chronic diseases. This study contributes to the literature by providing a comprehensive framework for understanding the complexities of dietary behavior transmission across generations.
