Summary
Lay health workers effectively increased hepatitis B virus (HBV) screening among Hmong Americans. Doctor recommendations were crucial for encouraging HBV testing and preventing liver cancer.
Area of Science:
- Public Health
- Hepatology
- Health Disparities
Background:
- Hepatitis B virus (HBV) infection is a primary driver of liver cancer, disproportionately impacting Hmong Americans with incidence rates 6-7 times higher than non-Hispanic Whites.
- Serologic testing for HBV is critical for early detection and prevention of liver cancer deaths in high-risk populations.
Purpose of the Study:
- To evaluate the effectiveness of a lay health worker (LHW) intervention in promoting hepatitis B virus (HBV) serologic testing among Hmong adults.
- To identify factors associated with increased HBV testing rates within this community.
Main Methods:
- A 5-year randomized controlled trial involving 260 Hmong adults.
- Intervention included in-home education and patient navigation by lay health workers (LHWs).
- Comparison between intervention and control groups on HBV testing rates and knowledge scores.
Main Results:
- Intervention group participants showed significantly higher HBV testing rates (24% vs. 10%) and increased knowledge scores compared to the control group.
- Multivariable analysis revealed that LHW intervention, improved knowledge, female gender, and prior doctor visits were associated with higher testing rates.
- Physician recommendation was the most frequently cited reason for undergoing HBV testing.
Conclusions:
- Lay health worker (LHW) interventions are effective in increasing hepatitis B virus (HBV) screening rates among Hmong Americans.
- The influence of healthcare providers and adherence to their recommendations are pivotal for enhancing HBV testing.
- Collaborative efforts involving healthcare providers are essential to improve HBV screening and reduce liver cancer incidence.

Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
