Table 3. Prevalence ratio for continuity of HIV care and HIV viral suppression by trajectory groups among 1,698 adults living with HIV/AIDS with recent experiences of jai incarceration and homelessness, New York City, June 2005-June 2006.

Trajectory groups	Continuity of HIV care		HIV viral suppression
	PR a , b	95% CI b	PR a , b	95% CI b
Temporary	1.04	0.82, 1.32	0.67	0.50, 0.90
Continuous incarceration	0.81	0.61, 1.07	0.62	0.43, 0.88
Continuous shelter use	0.76	0.49, 1.17	0.71	0.52, 1.22

CI, confidence interval; PR, prevalence ratio.

^aPrevalence ratio was estimated from log-linear Poisson models. Numbers in bold indicate statistical significance at p <0.05.

^bInverse probability of treatment weight was used to control for bias due to confounding. Covariates for the model for continuity of HIV care included age, sex, race/ethnicity, nativity, neighborhood poverty, a proxy measure of substance use, a proxy measure of mental illness, criminal charges due to drug sales, violent crimes, weapon possession, public administration, property crimes, quality of life crimes, sex crimes, ages of HIV diagnoses, and stage of HIV infection. The same sets of covariates except for criminal charges due to weapon possession were used for the model for viral suppression.
