Parents have a powerful influence on their children’s nutrition, physical activity, and lifestyle habits, which directly affect the risk for developing childhood obesity. Some family behaviors such as meal patterns, food selections, screen time, and physical activity habits may contribute to healthy development or, alternatively, unhealthy weight gain. Parents play a key role in modeling healthy eating behaviors, supporting regular physical activity, and achieving a balanced lifestyle. Family-based strategies for early intervention through education, nutrition, and physical activity can prevent obesity and have long-term health benefits for children. Recognizing how parental behavior may lead to childhood obesity provides insights to develop preventative strategies and interventions to build a healthier generation.
