Data analysis

Data was entered and analyzed using Stata statistical software; (StataCorp. 2017. Release 15. College Station, TX: StataCorp LLC). The categorical variables were presented as frequencies and percentages. The outcome of interest was correct identification of overweight/obesity status by physicians based on BMI calculations and BMI charting on CDC age, gender specific growth charts. The covariates studied included clinic site (pediatric vs. primary care), gender, age category, and BMI percentile group. Chi square test was used to determine any association between the covariates and the outcome variable. A p-value of <0.05 was considered to show a statistically significant association.

Approval from the Institutional Review Board (IRB) at the King Abdullah International Medical Research Center was obtained prior to conducting the study.
