PurposePortion size influences energy intake and is an important factor when developing weight management strategies. The effect of tableware on food intake is less clear, especially in children. To date, the relationship between the body weight of individuals and the tableware used in their households has not been investigated. The aim of this study was to analyze the sizes of tableware in households of children and adolescents with obesity (OBE) in comparison to participants with normal-weight matched for age and gender (NW).Methods60 OBE (32 female, 26 male) and 27 NW (12 female, 15 male) aged between 9 and 17 years participated in a structured interview on the tableware used at home. Responses were standardized based on the selection of different sizes of tableware and everyday objects presented to the children.ResultsIn households of NW, larger plates and bowls were used during meals and desserts compared to OBE. OBE drank out of larger bottles. Shapes and sizes of drinkware, the number of children drinking out of bottles and the cutlery used during dessert did not differ between the groups.ConclusionsDrinking out of large bottles may be an unfavourable habit of OBE if they contain sugar-rich liquids. The use of smaller plates and bowls of OBE may result in multiple helpings being consumed and so contribute to an overall increased portion size.Level Of EvidenceLevel V, Descriptive study.
