Objectives: We explored factors associated with perception of barriers to immunization among parents of Hmong origin in California, whose children experience persistent immunization inequities even with health insurance.
Methods: A partnership of academic researchers and members of the Hmong community conducted a community-based participatory research project. We collected data in naturalistic settings with a standardized instrument. We analyzed responses from 417 parents and caregivers and created a structural equation model to determine factors that contributed to perceived barriers.
Results: Of 3 potential contributing factors to perceived barriers-nativity, socioeconomic position, and use of traditional Hmong health care (i.e., consulting shamans and herbalists)-the latter 2 significantly predicted higher perceived barriers to immunization. Nativity, indicated by years in the United States, age of arrival in the United States, and English language fluency, did not predict perceived barriers.
Conclusions: Interventions aimed at reducing immunization inequities should consider distinct sociocultural factors that affect immunization rates among different refugee and immigrant groups.
