Purpose. To compare characteristics of hospitalized injuries among a sample of U.S. obese and non-obese persons.
Methods. Discharge records from the 2002 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project with an injury diagnosis were identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes. Records with multiple injury diagnoses or multiple external cause-of-injury codes were separated, and each type or cause was analyzed. Records with an exclusive obesity comorbidity were identified to compare injury characteristics between obese and non-obese persons. Proportional injury ratios (PIR) with 95% confidence intervals (CI) were calculated to compare injury characteristics.
Results. A total of 160,707 records were analyzed. Hospitalized injuries among obese persons were most frequent in persons aged 35-54 years (37.7%), in females (60.1%), in Whites (45.9%), and in persons with a household income greater than $45,000 (43.7%). Both type and cause of injury were significantly associated with obesity status (p < 0.001). Compared to non-obese persons, obese persons had significantly higher proportions of hospitalizations from sprains/strains (PIR=2.00, 95% CI: 1.77-2.26) and dislocations (PIR=1.94, 95% CI: 1.62-2.33) but lower proportions of hospitalizations from internal organ injuries (PIR=0.52, 95% CI: 0.43-0.63) and open wounds (PIR=0.76, 95% CI: 0.68-0.85). By cause, obese persons had significantly higher proportions of hospitalizations from falls (PIR=1.24, 95% CI: 1.16-1.34), overexertion (PIR=1.79, 95% CI: 1.41-2.26), and poisonings (PIR=1.26, 95% CI: 1.06-1.51).
Conclusions. Our results suggest that injuries in obese individuals may have distinct characteristics that warrant special consideration when developing injury prevention initiatives.
