37 Nevertheless, our findings may not be applicable to diagnoses of a disruptive behaviour disorder based on parent data, self-report data or multi-informant data, or indeed to other outcomes within this or other studies.
We assessed accuracy of child height, weight, and overweight/obesity classification in a pediatric clinic population based on parent data to learn whether accuracy differs by child age and race/ethnicity.
Because we had EHR data for all children, we were able to compare overweight/obesity and obesity prevalence based on parent-reported data versus measured height and weight data for the whole study population rather than just the subgroup of children who had data from both sources.
For the full sample and most subgroup comparisons, there were significant differences (15 percentage points on average) in prevalence of overweight/obesity and obesity based on parent-reported data for those children with usable BMI-for-age percentile data versus EHR data for all children in the sample (Table 4).
Due to the large number of children for whom a weight classification could not be assigned based on parent-reported data, we re-estimated the prevalence of overweight/obesity and obesity using parent-reported data weighted to reflect the age and gender counts for each race-ethnic group in the full sample.
As a consequence, similar to O'Connor and Gugenheim [ 12], we observed no bias due to missing data for this sample with regard to estimates of overweight/obesity or obesity based on parent-reported data.
A high level of acceptability was found for the program, and based on parent-report data, significant reductions were found in child shyness and in parent stress and anxiety from pre to post-intervention.
There is conflicting evidence about the accuracy of estimates of childhood obesity based on parent-reported data.
To do this, we compared the EHR-based prevalence of overweight/obesity and obesity for groups of children who did and did not have a usable weight classification based on parent-reported data.
This resulted in significantly lower percentages of Latino (45%) and Asian (43%) children compared to nonHispanic White children (68%) for whom a BMI-for-age percentile could be calculated and weight classification assigned based on parent-reported data.
As many other studies have found [ 4, 5, 7- 9, 11- 15], prevalence of overweight/obesity and obesity among these pre-school and pre-adolescent children based on parent-reported data of height and weight was significantly higher than prevalence based on actual measurements.
