Methods: The Kids data for the year 2006 provided by Agency for Healthcare Research and Quality was used. All hospitalizations (Unweighted N = 3,131,324) were selected for analysis. Kids with a co-morbid condition of obesity were identified. A multivariable matching approach was used were in kids with obesity were matched on age, sex, race, insurance status, type of admission, primary diagnosis, diagnosis related group, co-morbid condition severity, and hospital with those who were not obese. Non-parametric paired sample tests (Wilcoxon signed rank test and McNemar test) were used to compare the outcomes between obese and non-obese patients.
Results: Among the 3,131,324 hospitalizations, a total of 31,792 hospitalizations had obesity. Multivariable matching approach resulted in 11,369 obese hospitalizations being matched to their exact controls. Patients who were obese had close to $1,300 in extra hospital charges and half a day longer length of stay in hospitals (p<0.001) as compared to those who were not obese.
Conclusion: Obese patients were associated with marginally higher hospital charges and length of stay compared to non-obese patients for all hospitalizations in children and adolescents in United States.
