Zizza, Claire A.; Herring, Amy H.; Stevens, June; & Popkin, Barry M. (2004). Length of Hospital Stays among Obese Individuals. American Journal of Public Health, 94(9), 1587-1591. PMCID: PMC1448498


Objectives: We examined lengths of hospital stay among individuals categorized according to weight status.
Methods: We used data from the First National Health and Nutrition Examination Survey Epidemiologic Followup Survey to estimate length-of-stay differences.
Results: Individuals with body mass indexes (BMIs) of 35 kg/m2 or above, those with BMIs of 30 to 34 kg/m2, and those with BMIs of 25 to 29 kg/m2 had crude length-of-stay rates greater than those of normal-weight individuals. Association between BMI and length of stay varied over time.
Conclusions: Obese individuals experience longer hospital stays than normal-weight individuals.
