Positive change in health-related behaviour was defined as a positive change in any of: parent-reported diet, physical activity, screen-time behaviour, or health or leisure services use between baseline and one or six month follow-up. An individual with data at both one and six month follow-ups was categorised as having changed their behaviour if an improvement was observed at either time point. Positive change in diet was defined as an increase in healthy eating score between baseline and follow-up. The healthy eating score was derived from the frequency of consumption of fruits,

vegetables, sugary drinks, and snacks (Croker et al., 2012). For each food category, a score ranging from 1 to 7 was generated according to the frequency selleck compound NVP-BKM120 purchase of consumption (higher score for increasing consumption of fruit and vegetables, the reverse for other food categories); the healthy eating score was derived as a mean of these

scores, with a higher score indicating healthier eating behaviours. Improvement in physical activity was defined as a change from a child not meeting the national physical activity recommendation of 1 h per day at baseline (Department of Health, 2011), to achieving this level at follow-up. Improvement in screen-time behaviours was similarly defined as a change from not meeting screen-time recommendations of up to two hours per day at baseline (American Academy of Paediatrics, 2012), to meeting this level at follow-up. Positive change in the ADAMTS5 use of health or leisure services was defined as a change from not accessing any of these services for their child’s weight at baseline, to accessing one or more of these at follow-up. Predictor variables for intention to change health-related behaviour were: 1) parental recognition of their child’s overweight status (parents described their child as overweight or very overweight; parents of obese inhibitors children that described their child as overweight were considered to recognise

their child’s overweight status because they acknowledged an issue with excess weight), and 2) parental recognition of the health risks associated with their child’s overweight status (parents answered Yes to the question, Do you think your child’s current weight puts their health at risk?), at one month. The predictor variable for change in health-related behaviour was intention to change behaviour. Other predictors for both outcomes were ethnicity of child (white or non-white, from PCT records), child’s sex, child’s school year, child overweight status (overweight or obese, from NCMP), deprivation tertiles (using the Index of Multiple Deprivation IMD score, a measure of local area deprivation based on postal code), and PCT (an indicator of area level differences). The characteristics of the cohort were described using frequencies and percentages.
