Abstract

Background and aims We designed the school-based individual intervention to reduce the prevalence of obesity in primary school children through disclosure of dietary intake information. The aim of this study was to assess the effect of disclosure of dietary intake information on weight. Methods Schools were randomly allocated to an intervention (2 schools, n=810) or control (2 schools, n=1,373) groups which were first grade to fifth grade aged 6yr to 11yr. Of 641 participants (response rate: 29.4%), we analysed 156 participants in intervention group and 88 participants in control group without participants who could not assess outcome. We delivered self-reported questionnaire about weight at the beginning of September to both groups. In only intervention group, brief self-administered diet history questionnaire (BDHQ) (1) was additionally distributed to the parents. The individual dietary intake results from BDHQ were disclosed the parents of intervention school children with leaflet of paediatric obesity as the intervention. The outcome variables were change in self-reported weight during 1months after intervention. The outcomes were compared with groups categorised “Intervention non overweight and obese” vs“Control non overweight and obese” and “Intervention overweight and obese” vs “Control overweight and obese”. Overweight and obese is defined as obesity index :(real weight – standard weight)/standard weight×100, more than 10%. We used ANCOVA to assess differences in weight change between the groups. Results Significant difference between pre and post weight was found without intervention overweight and obese category. In contrast, no significant difference between pre and post weight was found with intervention group. Conclusion Disclosure of dietary intake information to parents appears to be useful to prevent weight gain in overweight and obese children.
