In adjusted analyses, models were adjusted for all other predictor variables. Robust standard errors were used to account for clustering by PCT. Results were presented as odds ratios (OR) and 95% confidence intervals (CI). A complete case

analysis was carried out for each regression model; this was considered reasonable because analysis of missing observations for predictor variables indicated that missingness was not associated with outcome variables. Potential modification of the main effects by child’s overweight category, child’s age, or PF-02341066 price PCT was assessed by the inclusion of interaction terms. All analyses were carried out using Stata version 12 (College Station, TX: StataCorp). Table 1 shows the study sample characteristics. Of the 3397 parents who responded to the baseline questionnaire (response rate = 18.9%), 579 (17.0% of respondents) had children who were classified as overweight or obese. Of these, 202 parents that responded at baseline and find more one month follow-up (34.9% of baseline sample) formed the sample for analysis of intention to change; 285 parents that responded at baseline and to at least one of the follow-up questionnaires (49.2% of baseline) formed the sample for analysis of behaviour change; 94% of parents in the sample recalled receiving the feedback letter.

At one month follow-up, 38.2% of parents of overweight children identified their child as overweight, and 28.7% recognised health risks associated with their child’s weight. Most parents (72.1%, n = 145) reported an intention to change health-related behaviours at one month; of these, 32 parents (22%) had not reported

an intention at baseline. In adjusted analyses (Table 2), intention to change behaviour was positively associated with parental recognition of child overweight status (odds ratio OR 11.20, 95% confidence interval CI 4.49, 27.93). Positive associations with parental recognition of health risks, child age and ethnicity that were observed in unadjusted analyses CYTH4 were attenuated in the adjusted model. Other a priori predictor variables were not associated with intention. Just over half (54.7%, n = 156 out of 285) of parents reported a positive change in health-related behaviours after receiving feedback about their child’s weight; 39.5% reported an improvement in diet, 14.0% an improvement in physical activity, 25.3% an improvement in screen-time, and 23.3% a positive change in service use. A third of parents (33.7%, n = 96) made changes to just one type of behaviour, 15.4% made changes to two behaviours, 6.0% to three, and 0.4% to all four. In adjusted analyses (Table 3), child’s school year was positively associated with behaviour change after NCMP feedback, with parents of children aged 10–11 more likely to report behaviour change than parents of children aged 4–5 (OR 1.91, 95% CI 1,35, 2.70).
