Abstract
Objectives.
Pediatric obesity is increasing at epidemic rates in industrialized nations. It is recommended that pediatricians screen all children annually with the use of body mass index (BMI). However, it is unclear whether this recommendation is followed. This study sought to (1) determine the proportion of children screened for obesity with BMI, and (2) test whether attending physicians are more likely than resident physicians to document and plot BMI.
Methods.
We conducted a systematic review of medical records in an urban academic pediatric practice. Participants were children aged 5 to 11 years presenting for health care in 2004. We measured the proportion of subjects with documented and plotted BMI and compared results for attending and resident physicians. We used logistic regression analysis to determine factors associated with documentation of BMI.
Results.
Of 397 medical records reviewed, 59.7% contained the 2000 Centers for Disease Control and Prevention growth curve with BMI for age; 5.5% documented BMI, and 4.3% plotted BMI. Resident physicians were more likely to document (13.0% vs. 3.0%, p=0.0008) and plot (9.0% vs. 2.7%, p=0.0260) BMI compared with attending physicians. Children with a BMI ≥95% for age were more likely to have their BMI documented (odds ratio [OR] = 10.7, 95% confidence interval [CI] 3.7, 31.5) and plotted (OR=7.1, 95% CI 2.3, 21.6).
Conclusion.
We found the use of BMI to screen for childhood obesity very poor in this academic pediatric practice. Resident physicians were more likely to document and plot BMI than attending physicians.
