Effect of Short-Term Barriers and Long-Term Health Considerations Among Patients Asked vs. Not Asked to Form Vaccination Intentions: Logistic Regression Analysis

	Patients NOT Asked Intention		Patients ASKED Intention
	First Dose Acceptance		Stated Intention to Accept 1^st Dose		Actual 1^st Dose Accepted
Independent Variables	Odds Ratio (95% CI)	P value	Odds Ratio (95% CI)	P value	Odds Ratio (95% CI)	P value
Short-Term Barriers
Perceived Discomfort	.68^a(.56–.82)	<.001	.89 (.72–1.1)	.29	.97 (.81–1.17)	.76
Perceived Inconvenience	.67 (.52–.87)	.002	.98 (.72–1.34)	.91	1.11 (.85–1.44)	.44
Long-Term Health Considerations
Perceived Vulnerability	1.55^b (1.19–2.0)	.001	2.41 (1.81–3.21)	<.001	1.77 (1.39–2.26)	<.001
Perceived Benefits	3.07 (2.14–4.42)	<.001	3.69 (2.49–5.46)	<.001	2.29 (1.64–3.19)	<.001

Note: Data from 1175 patients in urban STD clinics; 578 asked intention, 597 not asked intention.

Odds ratio of .68 indicates about a 32% decrease in the odds of first-dose acceptance for each one-unit increase in perceived vaccination discomfort.

Odds ratio of 1.55 indicates about a 55% increase in the odds of first-dose acceptance for each one-unit increase in perceived vulnerability to HBV infection.
