A Cluster Randomized Controlled Trial of a Lay Health Worker Intervention to Increase Healthy Eating and Physical Activity Among Vietnamese Americans.

Introduction: Americans have low levels of knowledge of and adherence to recommendations for healthy eating of fruits and vegetables and for physical activity (HEPA). We conducted a cluster randomized controlled trial of a lay health worker intervention to increase HEPA among Vietnamese Americans.

Methods: We randomized 64 lay health workers to 2 intervention arms.

Influenza and pneumococcal vaccination rates among Vietnamese, Asian, and non-Hispanic white Americans.

Background: Vaccination data for Asian Americans are comparable to those for whites, possibly because they are reported in aggregate rather than for subgroups. We compared influenza and pneumococcal vaccination rates among eligible Asian Americans and white Americans, and for Vietnamese Americans as a subgroup, and assessed factors associated with these vaccinations.

Methods: Cross-sectional study of data collected from three ethnic groups over 4 years by telephone survey.

Community-based participatory research increases cervical cancer screening among Vietnamese-Americans.

Using community-based participatory research methods, a community-research coalition in Santa Clara County, California (SCC) conducted a quasi-experimental, controlled trial to increase Pap test receipt and to build community capacity among Vietnamese-American women. From 1999 to 2004, the Coalition planned and implemented an Action Plan with six components: multimedia campaign, lay health worker outreach, Vietnamese Pap clinic with patient navigation, registry and reminder system, continuing medical education for Vietnamese physicians, and restoring a Breast and Cervical Cancer Control Program site. Components were evaluated individually.

Papanicolaou testing among Vietnamese Americans: results of a multifaceted intervention.

Background: Vietnamese-American women have the highest incidence of cervical cancer of any ethnic group, and they underutilize Papanicolaou (Pap) tests.

Design: Development and implementation of a multifaceted intervention using community-based participatory research (CBPR) methodology and evaluated with a quasi-experimental controlled design with cross-sectional pre-intervention (2000) and post-intervention (2004) telephone surveys. Data were analyzed in 2005.

Encouraging Vietnamese-American women to obtain Pap tests through lay health worker outreach and media education.

Background: Five times more Vietnamese-American women develop cervical cancer than white women. Few studies have examined whether community-based participatory research can effectively address Asian immigrants' health problems. This article reports the preliminary evaluation of 1 such project.
