CANCER CONTROL IN A VIETNAMESE AMERICAN POPULATION
Abstract
DESCRIPTION (Adapted from the Applicant's Abstract): Little is known about the
disease prevention behavior of Southeast Asian immigrants, and few studies have
addressed cancer control in this disadvantaged population. However, it is known
that two malignancies in particular, carcinoma of the cervix and hepatocellular
carcinoma, occur more frequently among Vietnamese Americans than among
individuals of an, other race/ethnicity. Almost all invasive cervical cancers
could be prevented by Papanicolaou testing, and up to 80 percent of liver
cancers could be prevented by hepatitis B vaccination. There is a clear need
for programs that can successfully enhance the uptake of Papanicolaou testing
among Vietnamese women; and increase the proportion of Vietnamese adults who
have been tested for evidence of hepatitis B infection (and, therefore, have
either been vaccinated, are screened for hepatocellular carcinoma, or know they
are immune). Cancer control programs targeting less acculturated immigrant
groups should be based on a thorough understanding of culturally based
attitudes and practices. The study has three specific objectives: collect
qualitative and quantitative data about the cervical and liver cancer
prevention behavior of Vietnamese Americans; design a culturally and
linguistically appropriate household cancer control intervention targeting
cervical cancer, hepatitis B infection, and hepatocellular carcinoma among
Vietnamese; and evaluate the intervention program's acceptability to the
Vietnamese community as well as its feasibility in terms of program delivery.
Community involvement will be emphasized. The PRECEDE framework and qualitative
methods will be used to guide the development of a quantitative survey
instrument. Qualitative and quantitative findings will both be used to develop
the intervention components. All interventions will be delivered by bicultural
Vietnamese outreach workers. A total of 60 Seattle households that under-use
preventive care will receive the intervention program; these households will be
identified from a population-based survey of 650 households. Intervention
components will include home visits, barrier specific counseling, the use of
videotapes and print materials, and logistic assistance. A comprehensive
process evaluation of the intervention will be conducted. If the intervention
program proves to be acceptable and feasible, the investigators will
subsequently apply for funding to conduct a randomized controlled trial and
evaluate the effectiveness of the program with respect to outcomes.
