Figure 1.
Evaluable Population for Obesity Analyses.
Development of the dataset for obesity-related analyses, showing the number of evaluable children and visits at each step. Percentages at each step are calculated relative to totals in the prior step. Since patients may have both primary care and specialty visits, subject counts at this step do not sum to the prior total; these values are marked with an asterisk.
Figure 2.
Comparison of EHR and NHANES 2007–8 Cohorts.
Average measured BMIs for children of both sexes at each month of age from 2–17 years in the multi-institutional EHR cohort and in the NHANES 2007–8 cohort. In addition to individual points, curves fitted to each dataset by cubic polynomial regression are shown.

Figure 3.
Diagnosis of Obesity at Outpatient Visits.
Percentages of children who were obese at any time during the study period, and diagnosed as obese at any visit to the indicated specialty. All specialties with a diagnosis rate ≥4% are included.
Figure 4.
Obesity-Related Co-Morbidities.
Standardized morbidity ratios (observed prevalence in obese children/expected prevalence from entire cohort) with 95% confidence intervals for diagnostic groups (EDCs) having SMR >1.5 and CI95>1.0 among children with measured obesity. N = total number of children in cohort with diagnosis in that EDC.
