Objective: To assess the accuracy of parents' perceptions of their 3 to 5 y old children's weight status in a large UK sample.
Method: Parental perception and concern about child weight, demographic variables, and children's height and weight were obtained for 564 parent-child dyads.
Results: Only 1.9% of parents of overweight children and 17.1% of parents of obese children described their child as overweight. The odds of parents perceiving the child as overweight were increased for overweight (2.7; 95% CI 0.4, 16.5) and obese (28.5; 7.1, 115.4) compared with normal weight children, but were not associated with parental weight or with any demographic factors. Although few parents perceived their overweight children as overweight, more (66.2%) expressed concern about their overweight child becoming overweight in the future. Odds of concern were progressively higher for overweight (2.5; 1.6, 3.9) and obese children (4.6; 2.2, 9.7), and were also higher for parents who were themselves overweight (1.9; 1.2, 2.9) or obese (2.5; 1.3, 4.8).
Conclusion: These findings suggest that parents of 3-5 y olds show poor awareness of their child's current weight status. Reframing discussions in terms of preventing future overweight may be an effective way to engage parents.
