AbstractSouth Asian women living in the UK are particularly at high risk of obesity-related complications, such as type 2 diabetes and cardio-vascular disease. Exposure to large portion sizes is a risk factor for obesity. Specifically, designed tableware helps individuals to manage weight through controlling food portion sizes. Thirty-one (n=31) overweight or obese South Asian adult women participated in a randomised cross-over trial aimed to assess efficacy, acceptance and weight change for two guided/calibrated commercially available portion control tools (Utensil set and Crockery Set) used in free-living conditions. Data on acceptance, perceived changes in portion size, frequency, and meal type was collected using paper questionnaires and 3-day diet dairies. Scores describing acceptance, ease of use and perceived effectiveness were derived from five-point Likert scales from which binary indicators (high/low) were analysed for significance using multivariate variance analysis for repeated measurements. A reduction in BMI was observed at each point of measurement (p=0.007). For overall tool use, the crockery set scored higher in all areas of acceptance, ease of use, perceived efficacy for all comparisons. Self-selected portion sizes increased for salads and decreased for cooking oil and breakfast cereals with both tools. Further research to scale up and evaluate similar weight management interventions for this group are warranted.
