Trial Information

Community-Based Hepatitis B Interventions for Hmong Adults

The investigators will design an intervention to measure the baseline proportion of Hmong
adults (ages 18-64) that have been serologically tested for Hepatitis B. Investigators will
work with lay health workers to promote serologically testing for Hepatitis B and increase
knowledge of Hepatitis B among Hmong adults. The effectiveness of the lay health worker
intervention will be evaluated by conducting a randomized, controlled trial among Hmong
adults aged 18-64 not previously tested for hepatitis B.

The primary hypothesis is that the proportion of Hmong adults, ages 18-64 reporting
serologically testing for Hepatitis B at post-test will be significantly greater in the
intervention group than in the control group.

Secondary hypotheses are:

There will be greater increases in knowledge of Hepatitis B and liver cancer in the
intervention group than in the control group.

Participants with greater knowledge of hepatitis B and liver cancer at post-test will be
more likely to be serologically tested for hepatitis B.
