Methicillin-Resistant Staphylococcus aureus Infections in Human Immunodeficiency Virus-Infected Children and Adolescents

Table 2

Factors associated with MRSA infection in multivariable analysis, the LEGACY Study, 2006.

	Initial multivariable model (𝑁=1,756)			Final reduced multivariable model (𝑁=1,797)
Characteristic	aOR	95% CI	𝑃 value	aOR	95% CI	𝑃 value
Maryland care site^1	7.4	2.4, 23.2	0.0006	9.0	3.0, 26.8	<0.0001
CD4 <200 cells/μL^2	1.6	0.43, 5.7	0.50	—	—	—
Behavioral risk^3	1.9	0.5, 7.3	0.34	—	—	—
Viral load >1000 copies/mL^4	4.6	1.0, 22.0	0.056	5.9	1.3, 26.5	0.02
Age ≥15 years^5	1.4	0.30, 6.1	0.69	—	—	—
Non-Hispanic black^6	Und^7	Und^7	0.035	Und^7	Und^7	0.044

Comparing: ¹Maryland care site versus all other care sites; ²CD4 <200 cells/μL versus CD4 ≥200 cells/μL; ³Behavioral HIV infection risk versus all other HIV risk categories; ⁴HIV RNA viral load >1000 copies/mL versus viral load ≤1000 copies/mL; ⁵Age ≥15 years versus age <15 years; ⁶Non-Hispanic black versus all other racial/ethnic groups; ⁷Undefined aOR because all MRSA cases were black race.
aOR: adjusted Odds Ratio.
MRSA: methicillin-resistance Staphylococcus aureus.
