Study title

The APPETItE data comprises a multiple mixed methods approach, including an online survey of feeding practices and perceptions of child food approach behaviours, a qualitative study of parents’ experiences of feeding children with avid appetites, an ecological momentary assessment study to capture emotion and feeding practice across time and context, as well as a randomized controlled experiment to examine effects of feeding practice on child food intake. Types of data: Data generated were both quantitative and qualitative. New data were generated by a survey, interviews, ecological momentary analysis, experimental laboratory methods, and co-creation methods. All pre-registrations, data, data dictionaries and analysis code are openly available as soon as study papers are published at https://osf.io/r6789/Childhood obesity is one of the most serious public health challenges of the 21st century, of major societal concern, placing children at high risk of diseases such as diabetes, cardiovascular disease and some cancers in adulthood. Typically, childhood obesity begins in infancy and early childhood, with 90% of children who have obesity at 3 years continuing to have overweight or obesity in adolescence. Understanding the factors which may help to prevent or reduce the risk of childhood obesity, and applying this understanding to develop effective interventions, is of key importance to solving this complex policy and practice challenge. It is well established that a healthy home environment is protective against the development of obesity. However, some children are more vulnerable to the development of obesity than others, due to their genetic susceptibility to an environment where highly palatable food is plentiful and accessible. Children's appetite and eating behaviours link this genetic risk and the development of obesity. Children's appetite avidity is manifest in their 'food approach' behaviours, which have considerable heritability. Food approach...
