RESUMO
OBJECTIVES: We conducted a cluster randomized controlled study of a lay health worker (LHW) intervention to increase colorectal cancer (CRC) screening rates among Vietnamese Americans, who typically have lower rates than do non-Hispanic Whites. METHODS: We randomized 64 LHWs to 2 arms. Each LHW recruited 10 male or female participants who had never had CRC screening (fecal occult blood test, sigmoidoscopy, or colonoscopy). Intervention LHWs led 2 educational sessions on CRC screening. Control LHWs led 2 sessions on healthy eating and physical activity. The main outcome was self-reported receipt of any CRC screening at 6 months after the intervention. We conducted the study from 2008 to 2013 in Santa Clara County, California. RESULTS: A greater proportion of intervention participants (56%) than control participants (19%) reported receiving CRC screening (P < .001). When controlling for demographic characteristics, the intervention odds ratio was 5.45 (95% confidence interval = 3.02, 9.82). There was no difference in intervention effect by participant gender. CONCLUSIONS: LHW outreach was effective in increasing CRC screening in Vietnamese Americans. Randomized controlled trials are needed to test the effectiveness of LHW outreach for other populations and other health outcomes.

The purpose of this study was to better understand if a health educational presentation using culturally adapted materials was understandable and culturally appropriate, and that the content was retained, in an older Vietnamese American population. This study used cognitive interviewing. A convenient sampling was used to recruit eight participants by staff of a community-based organization from its client base. This is the first study to document that family eating style poses a challenge for estimating food intake among Vietnamese Americans. Participants who ate in a family eating style were not able to recall or estimate the number of servings of protein and vegetables. Some older Vietnamese Americans used food for healing and self-adjusted portion sizes from dietary recommendations. Cognitive interviewing is a useful method to improve comprehension, retention, and cultural appropriateness of health educational materials. Further nutrition research concerning intake measurement in ethnic groups that practice a family eating style is warranted.

BACKGROUND: Vietnamese-American women underutilize breast cancer screening. DESIGN: An RCT was conducted comparing the effect of lay health workers (LHWs) and media education (ME) to ME alone on breast cancer screening among these women. SETTING/PARTICIPANTS: Conducted in California from 2004 to 2007, the study included 1100 Vietnamese-American women aged > or = 40 years who were recruited through LHW social networks. Data were analyzed from 2007 to 2009. INTERVENTION: Both groups received targeted ME. The intervention group received two LHW educational sessions and two telephone calls. MAIN OUTCOME MEASURES: Change in self-reported receipt of mammography ever, mammography within 2 years, clinical breast examination (CBE) ever, or CBE within 2 years. RESULTS: The LHW+ME group increased receipt of mammography ever and mammography in the past 2 years (84.1% to 91.6% and 64.7% to 82.1%, p<0.001) while the ME group did not. Both ME (73.1% to 79.0%, p<0.001) and LHW+ME (68.1% to 85.5%, p<0.001) groups increased receipt of CBE ever, but the LHW+ME group had a significantly greater increase. The results were similar for CBE within 2 years. In multivariate analyses, LHW+ME was significantly more effective than ME for all four outcomes, with ORs of 3.62 (95% CI=1.35, 9.76) for mammography ever; 3.14 (95% CI=1.98, 5.01) for mammography within 2 years; 2.94 (95% CI=1.63, 5.30) for CBE ever; and 3.04 (95% CI=2.11, 4.37) for CBE within 2 years. CONCLUSIONS: Lay health workers increased breast cancer screening among Vietnamese-American women.Future research should focus on how LHWs work and whether LHW outreach can be disseminated to other ethnic groups [corrected].

BACKGROUND: There are few population-based studies of cardiovascular risk factors, knowledge, and related behaviors among Vietnamese Americans. OBJECTIVE: To describe cardiovascular risk factors, knowledge, and related behaviors among Vietnamese Americans and compare the results to non-Hispanic whites. DESIGN: Comparison of data from two population-based, cross-sectional telephone surveys. PARTICIPANTS: Vietnamese Americans in Santa Clara County, California, and non-Hispanic whites in California, aged 18 and older. MEASUREMENTS: Survey measures included sociodemographics, diagnoses, body mass index, fruit and vegetable intake, exercise, and tobacco use. Knowledge of symptoms of heart attack and stroke was collected for Vietnamese Americans. MAIN RESULTS: Compared to non-Hispanic whites (n = 19,324), Vietnamese Americans (n = 4,254) reported lower prevalences of obesity, diabetes mellitus, coronary heart disease, and hypertension, and similar prevalences of stroke and hypercholesterolemia. Fewer Vietnamese Americans consumed fruits and vegetables five or more times daily (27.8% vs 16.3%, p < 0.05), and more reported no moderate or vigorous physical activity (12.1% vs 40.1%, p < 0.05). More Vietnamese men than non-Hispanic White men were current smokers (29.8% vs 19.0%, p < 0.05). Vietnamese Americans who spoke Vietnamese were more likely than those who spoke English to eat fruits and vegetables less frequently, engage in no moderate or vigorous physical activity, and, among men, be current smokers. Only 59% of Vietnamese Americans knew that chest pain was a symptom of heart attack. CONCLUSIONS: There are significant disparities in risk factors and knowledge of symptoms of cardiovascular diseases among Vietnamese Americans. Culturally appropriate studies and interventions are needed to understand and to reduce these disparities.

OBJECTIVES: We sought to promote cervical cancer screening among Vietnamese American women in Santa Clara County, Calif. METHODS: In 2001-2004, we recruited and randomized 1005 Vietnamese American women into 2 groups: lay health worker outreach plus media-based education (combined intervention) or media-based education only. Lay health workers met with the combined intervention group twice over 3 to 4 months to promote Papanicolaou (Pap) testing. We used questionnaires to measure changes in awareness, knowledge, and Pap testing. RESULTS: Testing increased among women in both the combined intervention (65.8% to 81.8%; P<.001) and media-only (70.1% to 75.5%; P<.001) groups, but significantly more in the combined intervention group (P=.001). Among women never previously screened, significantly more women in the combined intervention group (46.0%) than in the media-only group (27.1%) obtained tests (P<.001). Significantly more women in the combined intervention group obtained their first Pap test or obtained one after an interval of more than 1 year (became up-to-date; 45.7% to 67.3%, respectively; P<.001) than did those in the media-only group (50.9% to 55.7%, respectively; P=.035). CONCLUSIONS: Combined intervention motivated more Vietnamese American women to obtain their first Pap tests and to become up-to-date than did media education alone.

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. Community-wide, cross-sectional telephone surveys of Vietnamese women in SCC (intervention community) and Harris County, Texas (comparison community) measured overall project impact. Receipt and currency of Pap tests increased significantly in the intervention compared with the comparison community. Community involvement, system changes, community and research capacity building, dissemination of results, and program sustainability were also demonstrated. Community-based participatory research is feasible and effective in Vietnamese-American communities.

The authors organized a lay health worker (LHW) outreach program with Vietnamese women that produced significant increases in Pap testing. The program was conducted by five partner agencies and 50 LHWs and involved 1,005 women. This article reports on the roles of the agencies and coordinators, the selection of LHWs, the processes LHWs used in identifying and recruiting participants, the ways they conducted their outreach work, and their strategies for maintaining participation. The article also reports on the LHWs' perspectives about how they benefited and what they found to be most rewarding and challenging about being a LHW. Based on the analysis of this information, the authors present a conceptual framework for understanding how different contextual factors shape the processes and capacity-building benefits of LHW outreach, describing four contextual domains that shape LHW outreach: the sociocultural domain and organizational domain, which overlap in the programmatic domain, all of which are framed by the structural domain. This analysis provides an approach for understanding how lay health work is shaped by a broader context.

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. SETTING: Santa Clara County, California (intervention community) and Harris County, Texas (comparison community). PARTICIPANTS: Vietnamese-American women aged 18 and older (n =1566 at pre-intervention and 2009 at post-intervention). INTERVENTION: A community-academic coalition developed and implemented six components: Vietnamese-language media campaign, lay health worker outreach, Vietnamese Pap clinic, patient registry/reminder system, restoration of a government-funded low-cost screening program, and continuing medical education for Vietnamese physicians. OUTCOME MEASURE: Pap test receipt. RESULTS: Overall response rate was 56%. Pap test receipt increased in the intervention (77.5% to 84.2%, p <0.001), but not in the comparison community (73.9% to 70.6%, p >0.05). In multivariate analyses, the intervention was associated with increased Pap test receipt (odds ratio [OR]=2.02, 95% confidence interval [CI]=1.37-2.99). Other factors associated with increased Pap testing included longer U.S. residence, having health insurance, having a regular site of care, having a respectful physician, having a non-Vietnamese or a female Vietnamese physician, and recalling exposure to Vietnamese-language media about Pap testing. Factors associated with reduced likelihood of Pap test receipt were age 65 years and older, never married, less than high school education, and income below poverty level. CONCLUSIONS: A multifaceted CBPR intervention was associated with increased Pap test receipt among Vietnamese-American women in one community.
