Predictors of Higher Community-Associated Methicillin-Resistant Staphylococcus aureus Colonization Burden on Multivariable Analysis

Predictor	Relative Prevalence (95% CI)	P Value
HIV-infected individuals
Hispanic ethnicity	0.39 (.23–.66)	<.001
Incarceration exposure: current detainee or release in past 3 mo	1.66 (1.06–2.59)	.027
Male sex	1.53 (1.06–2.2)	.023
Age (in decades)	0.87 (.76–.99)	.033
HIV-negative individuals
Temporary housing	2.14 (1.12–4.1)	.021

Temporary housing is defined as homeless or residing in a shelter or substance abuse center currently or in the prior year. Colonization burden is defined as the number of colonized sites divided by the total number of sites sampled. Initial variables included in the model were human immunodeficiency virus status, sex, race, ethnicity, incarceration exposure, temporary housing, illicit drug use, age, and residence in a nursing home or long-term care facility in the past year.

Abbreviations: CI, confidence interval; HIV, human immunodeficiency virus.
