Effect of a media intervention on hepatitis B screening among Vietnamese Americans.

Objective: There is a lack of controlled studies of community-wide interventions to increase screening for hepatitis B (HBV) among Asian Americans, particularly Vietnamese Americans, who disproportionately suffer from HBV-related illnesses. The objective of our study was to develop, implement, and evaluate the effectiveness of a media campaign to promote HBV screening among Vietnamese Americans.Design: We designed and implemented a three-year media campaign promoting HBV screening among Vietnamese Americans. Evaluation consisted of cross-sectional pre- and post-intervention population-based telephone surveys of Vietnamese Americans adults age 18-64 who spoke English or Vietnamese and lived in the Northern California (intervention) or Greater Washington, D.C. (comparison) communities in 2007 or 2011. Statistical analysis was completed in 2012. The main outcome was self-report of HBV testing, defined as participants answering 'Yes' to the question: 'Have you ever had a blood test to check for hepatitis B?'Results: The sample sizes at pre- and post-intervention were 1,704 and 1,666, respectively. Both communities reported increased exposure to HBV-related booklets, radio and television advertisements, and websites. Only the intervention community reported increased exposure to newspaper elements. HBV screening increased in both communities (intervention: 65.3% to 73.1%, p < 0.01, comparison: 57.7% to 66.0%, p < 0.01). In multivariable analyses, there was no intervention effect. In both communities, exposure to media elements (Odds Ratio 1.26 [95% Confidence Interval: 1.21, 1.31] for each additional element) was significantly associated with screening.Conclusions: Among Vietnamese Americans in 2 large communities, HBV screening rates were sub-optimal. Screening increased in both the intensive media intervention and comparison communities, and exposure to HBV-related media messages was associated with increased screening. Efforts to address HBV screening among Vietnamese Americans should include mass media messaging.

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. Each lay health worker recruited 10 participants aged 50 to 74. From 2008 to 2013, using flip charts, lay health workers led 2 educational sessions on HEPA (intervention) or colorectal cancer (comparison). We assessed HEPA knowledge and self-reported behaviors by preintervention and postintervention surveys 6 months apart. RESULTS: Of the 640 participants, 50.0% were female, 38.4% had lived in the United States for 10 years or fewer, and 71.4% reported limited English proficiency. Knowledge of the recommended intake of fruits and vegetables (≥5 servings daily) increased from 2.6% to 60.5% in the intervention group (n = 311) and from 2.9% to 6.7% in the comparison group (n = 316) (intervention vs comparison change, P < .001). Knowledge of the physical activity recommendation (≥150 minutes weekly) increased from 2.6% to 62.4% among intervention participants and from 1.0% to 2.5% among comparison participants (P < .001). Consumption of 5 or more daily servings of fruits and vegetables increased more in the intervention group (8.4% to 62.1%) than in the comparison group (5.1% to 12.7%) (P < .001). Participants reporting 150 minutes or more of physical activity weekly increased from 28.9% to 54.0% in the intervention group and from 38.0% to 46.8% in the comparison group (intervention vs comparison change, P = .001). CONCLUSION: A lay health worker intervention increased both healthy eating and physical activity knowledge and self-reported behaviors among older Vietnamese Americans.

Preferences for Depression Help-Seeking Among Vietnamese American Adults.

Culture impacts help-seeking preferences. We examined Vietnamese Americans' help-seeking preferences for depressive symptoms, through a telephone survey (N = 1666). A vignette describing an age- and gender-matched individual with depression was presented, and respondents chose from a list of options and provided open-ended responses about their help-seeking preferences. Results showed that 78.3% would seek professional help, either from a family doctor, a mental health provider, or both; 54.4% preferred to seek help from a family doctor but not from a mental health provider. Most (82.1%) would prefer to talk to family or friends, 62.2% would prefer to look up information, and 50.1% would prefer to get spiritual help. Logistic regression analysis revealed that preferences for non-professional help-seeking options (such as talking to friends or family, looking up information, and getting spiritual help), health care access, and perceived poor health, were associated with increased odds of preferring professional help-seeking. This population-based study of Vietnamese Americans highlight promising channels to deliver education about depression and effective help-seeking resources, particularly the importance of family doctors and social networks. Furthermore, addressing barriers in access to care remains a critical component of promoting professional help-seeking.

Educational Interventions to Promote Healthy Nutrition and Physical Activity Among Older Chinese Americans: A Cluster-Randomized Trial.

OBJECTIVES: To evaluate the efficacy of an in-language intervention of 2 lectures plus printed materials versus printed materials alone on knowledge and adherence to nutrition and physical activity guidelines among older Chinese Americans in San Francisco, California. METHODS: From August 2010 to September 2013, we randomized 756 Chinese Americans aged 50 to 75 years to either lectures plus print (n = 361) or print (n = 357). Clusters were the participants recruited by each lay health worker. Intervention outcomes were changes in knowledge of recommended vegetable intake, fruit intake, and physical activity level and adherence to those recommendations from pre- to 6 months postintervention. RESULTS: The retention rate was 99%. At baseline, knowledge and adherence to recommendations were low. Print yielded increases in knowledge of recommended vegetable intake and physical activity level and adherence to fruit intake and physical activity recommendations. Lectures plus print had significant increases in all 6 outcomes. In multivariable models, lectures plus print was superior to print for knowledge of vegetable (adjusted odds ratio [AOR] = 12.61; 95% confidence interval [CI] = 6.50, 24.45) and fruit (AOR = 16.16; 95% CI = 5.61, 46.51) intake recommendations and adherence to vegetable intake recommendations (AOR = 5.53; 95% CI = 1.96, 15.58). CONCLUSIONS: In-language print materials, alone and combined with lectures, increased nutrition and physical activity knowledge and behaviors among older Chinese Americans.

Healthcare Communication Barriers and Self-Rated Health in Older Chinese American Immigrants.

Older Chinese immigrants are a growing population in the United States who experience multiple healthcare communication barriers such as limited English proficiency and low health literacy. Each of these obstacles has been associated with poor health outcomes but less is known about their effects in combination. This study examined the association between healthcare communication barriers and self-rated health among older Chinese immigrants. Cross-sectional survey data were obtained from 705 Chinese American immigrants ages 50-75 living in San Francisco, California. Communication barriers examined included spoken English proficiency, medical interpreter needs, and health literacy in written health information. The study sample (81 % females, mean age = 62) included 67 % who spoke English poorly or not at all, 34 % who reported needing a medical interpreter, and 37 % who reported "often" or "always" needing assistance to read health information. Two-thirds reported poor self-rated health; many reported having access to racial-concordant (74 %) and language-concordant (86 %) healthcare services. Both poor spoken English proficiency and low health literacy were associated with poor self-rated health, independent of other significant correlates (unemployment, chronic health conditions, and having a primary doctor who was ethnic Chinese). Results revealed that spoken English proficiency and print health literacy are independent communication barriers that are directly associated with health status among elderly Chinese American immigrants. Access to racial- or language-concordant health care services did not appear to resolve these barriers. These findings underscore the importance of addressing both spoken and written healthcare communication needs among older Chinese American immigrants.

Suffering in Silence: Impact of Tobacco Use on Communication Dynamics Within Vietnamese and Chinese Immigrant Families.

The goal of this project was to explore family communication dynamics and their implications for smoking cessation. We conducted 39 in-depth dyadic and individual qualitative interviews with 13 immigrant smoker-family member pairs of Vietnamese ( n = 9 dyads, 18 individuals) and Chinese ( n = 4 dyads, 8 individuals) descent, including seven current and six former smokers and 13 family members. All 13 dyadic and 26 individual interviews were analyzed using a collaborative crystallization process as well as grounded theory methods. We identified three interrelated pathways by which tobacco use in immigrant Vietnamese and Chinese families impacts family processes and communication dynamics. Using a two-dimensional model, we illustrate how the shared consequences of these pathways can contribute to a dynamic of avoidance and noncommunication, resulting in individual family members "suffering in silence" and ultimately smoking being reinforced. We discuss the implications of these findings for development of smoking cessation interventions.

Effectiveness of Lay Health Worker Outreach in Reducing Disparities in Colorectal Cancer Screening in Vietnamese Americans.

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.

A Social Network Family-Focused Intervention to Promote Smoking Cessation in Chinese and Vietnamese American Male Smokers: A Feasibility Study.

INTRODUCTION: Smoking prevalence is high among limited English-proficient Chinese and Vietnamese American men, who are frequently unmotivated to quit and who underutilize smoking cessation resources. This study applied lay health worker outreach to leverage peer and family networks to promote smoking cessation among these men. METHODS: We integrated qualitative formative research findings and Social Network Theory to develop a social-network family-focused intervention. In a pilot single-group trial, 15 lay health workers recruited 96 dyads (N = 192, 75% Vietnamese) of Chinese or Vietnamese male daily smokers and their family members and delivered the intervention consisting of two small group education sessions and two individual telephone calls over 2 months. RESULTS: At baseline, 42% of smokers were at precontemplation. At 3 months following the initiation of the intervention, 7-day and 30-day point prevalence smoking abstinence rates as reported by smokers and independently corroborated by family members were 30% and 24%, respectively. Utilization of smoking cessation resources (medication, quitline, physician's advice) increased from 2% to 60% (P < .001). Findings showed high acceptability of the intervention as it facilitated learning about tobacco-related health risks and cessation resources, and communications between smokers and their families. CONCLUSIONS: This novel social network family-focused intervention to promote smoking cessation among Chinese and Vietnamese smokers appears to be acceptable, feasible, and potentially efficacious. Findings warrant evaluation of long-term efficacy of the intervention in a larger scale randomized controlled trial.

Cognitive Interviews of Vietnamese Americans on Healthy Eating and Physical Activity Health Educational Materials.

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.

Understanding and use of nicotine replacement therapy and nonpharmacologic smoking cessation strategies among Chinese and Vietnamese smokers and their families.

INTRODUCTION: Population-based studies have reported high rates of smoking prevalence among Chinese and Vietnamese American men. Although nicotine replacement therapy (NRT) is effective, recommended, and accessible without prescription, these populations underuse NRT for smoking cessation. The aim of this study was to assess understanding and use of NRT and nonpharmacologic treatments among Chinese and Vietnamese American male smokers and their families. METHODS: In-depth qualitative interviews were conducted with 13 smoker-family pairs, followed by individual interviews with each participant. A total of 39 interviews were conducted in Vietnamese or Chinese, recorded, translated, and transcribed into English for analysis. RESULTS: Four themes were identified: use and understanding of NRT, nonpharmacologic strategies, familial and religious approaches, and willpower. Both smokers and their family members believed strongly in willpower and a sense of personal responsibility as the primary drivers for stopping smoking. Lack of these 2 qualities keeps many Chinese and Vietnamese men from using NRT to quit smoking. Those who do use NRT often use it incorrectly, following their own preferences rather than product instructions. CONCLUSION: Our findings indicate the importance of culturally appropriate patient education about NRT. It may be necessary to teach smokers and their families at an individual level about NRT as a complementary approach that can strengthen their resolve to quit smoking. At a community level, public health education on the indication and appropriate use of evidence-based smoking cessation resources, such as NRT, would be an important component of effective tobacco control.

Neighborhood Ethnic Composition and Self-rated Health Among Chinese and Vietnamese American Immigrants.

Immigrants tend to live in areas with higher co-ethnic density, and the effect of neighborhood ethnic composition could be particularly salient for health. This study explored associations between neighborhood ethnic composition and self-rated health among Asian immigrants. We analyzed data collected at baseline from 670 Chinese and Vietnamese immigrants enrolled in a lifestyle intervention trial. Residential addresses were geocoded and combined with neighborhood socio-demographic profiles based on census data. We used generalized estimating equations to examine neighborhood ethnic composition and self-rated health. Independent of individual-level factors, living in neighborhoods more densely populated by whites was associated with poor/fair self-rated health. Neighborhood household income and density of participants' own ethnic group were not associated with poor/fair self-rated health. More research is warranted to disentangle reasons why Chinese and Vietnamese immigrants living in white-concentrated neighborhoods reported poorer self-rated health, including investigating effects of discrimination, relative deprivation, and availability of social resources.

Factors associated with hepatitis B testing among Vietnamese Americans.

BACKGROUND: Chronic hepatitis B and hepatitis B-associated liver cancer is a major health disparity among Vietnamese Americans, who have a chronic hepatitis B prevalence rate of 7-14% and an incidence rate for liver cancer six times that of non-Latino whites. OBJECTIVE: Describe factors associated with hepatitis B testing among Vietnamese Americans. DESIGN: A population-based telephone survey conducted in 2007-2008. PARTICIPANTS: Vietnamese Americans age 18-64 and living in the Northern California and Washington, DC areas (N = 1,704). MAIN MEASURES: Variables included self-reports of sociodemographics, health care factors, and hepatitis B-related behaviors, knowledge, beliefs, and communication with others. The main outcome variable was self-reported receipt of hepatitis B testing. KEY RESULTS: The cooperation rate was 63.1% and the response rate was 27.4%. Only 62% of respondents reported having received a hepatitis B test and 26%, hepatitis B vaccination. Only 54% knew that hepatitis B could be transmitted by sexual intercourse. In multivariable analyses, factors negatively associated with testing included: age 30-49 years, US residence for >10 years, less Vietnamese fluency, lower income, and believing that hepatitis B can be deadly. Factors positively associated with testing included: Northern California residence, having had hepatitis B vaccination, having discussed hepatitis B with family/friends, and employer requested testing. Physician recommendation of hepatitis B testing (OR 4.46, 95% CI 3.36, 5.93) and respondent's request for hepatitis B testing (OR 8.37, 95% CI 5.95, 11.78) were strongly associated with test receipt. CONCLUSION: Self-reports of hepatitis B testing among Vietnamese Americans remain unacceptably low. Physician recommendation and patient request were the factors most strongly associated with test receipt. A comprehensive effort is needed to promote hepatitis B testing in this population, including culturally-targeted community outreach, increased access to testing, and physician education.

Effectiveness of a controlled trial to promote colorectal cancer screening in Vietnamese Americans.

OBJECTIVES: We conducted a controlled trial of a public education and provider intervention to increase colorectal cancer (CRC) screening rates among Vietnamese Americans, who typically have lower rates than non-Hispanic Whites. METHODS: The public education intervention included a Vietnamese-language CRC screening media campaign, distribution of health educational material, and a hotline. The provider intervention consisted of continuing medical education seminars, newsletters, and DVDs. Vietnamese in Alameda and Santa Clara Counties, California, received the intervention from 2004 to 2006; Vietnamese in Harris County, Texas, were controls and received no intervention. A quasi-experimental study design with pre- and postintervention surveys of the same 533 participants was used to evaluate the combined intervention. RESULTS: The postintervention-to-preintervention odds ratio for having ever had a sigmoidoscopy or colonoscopy was 1.4 times greater in the intervention community than in the control community. Knowledge and attitudes mediated the effect of the intervention on CRC screening behavior. Media exposure mediated the effect of the intervention on knowledge. CONCLUSIONS: Improving CRC knowledge through the media contributed to the effectiveness of the intervention.

Serious quit attempts and cessation implications for Asian American male smokers.

INTRODUCTION: Smoking prevalence remains high among Asian American immigrant men, particularly those with limited English proficiency. Understanding ways to promote serious quit attempts (defined as a quit attempt lasting at least 24 h) could be crucial for reducing tobacco-related health disparities in this population. This study examines correlates of serious past year quit attempts among Chinese and Vietnamese American male daily smokers. METHODS: Baseline survey data were collected between 2015 and 2017 from a lifestyle intervention trial (N = 340 Chinese and Vietnamese male daily smokers). Data analysis was conducted in 2019. Multivariable logistic regression analysis was used to identify factors associated with serious past year quit attempts. RESULTS: Less than half (43.2%) of the study participants had at least one serious past year quit attempt. Significant correlates of serious quit attempts included utilizing evidence-based methods (OR = 12.83, 95% CI 5.17-31.84) or other methods (OR = 3.92, 95% CI 3.92-13.73) to facilitate quitting compared to those who did not attempt to quit. Also, participants who had a physician encounter in the past year were more likely to have had a serious quit attempt (OR = 2.25, 95% CI 1.12-4.53). Discussing smoking during a past year doctor's visit, however, was not a significant correlate of serious quit attempts. CONCLUSIONS: Our findings underscore the importance of promoting the use of smoking cessation resources, and potentially utilizing healthcare encounters to facilitate cessation. Investigations are warranted to understand better how patient-physician interactions can enhance smoking cessation.

Cardiovascular risk factors and knowledge of symptoms among Vietnamese Americans.

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.

Offering annual fecal occult blood tests at annual flu shot clinics increases colorectal cancer screening rates.

PURPOSE: We wanted to determine whether providing home fecal occult blood test (FOBT) kits to eligible patients during influenza inoculation (flu shot) clinics can contribute to higher colorectal cancer screening (CRCS) rates. METHODS: The study was time randomized. On 8 dates of an annual flu shot clinic at the San Francisco General Hospital, patients were offered flu shots as usual (control group) and on 9 other dates, patients were offered both flu shots and FOBT kits (intervention group). RESULTS: The study included 514 patients aged 50 to 79 years, with 246 in the control group and 268 in the intervention group. At the conclusion of flu season, FOBT screening rates increased by 4.4 percentage points from 52.9% at baseline to 57.3% (P = .07) in the control group, and increased by 29.8 percentage points from 54.5% to 84.3% (P <.001) in the intervention group, with the change among intervention participants 25.4 percentage points greater than among control participants (P value for change difference <.001). Among patients initially due for CRCS, 20.7% in the control group and 68.0% in the intervention group were up-to-date at the conclusion of the study (P <.001). In multivariate analyses, the odds ratio for becoming up-to-date with screening in the intervention group (vs the control group) was 11.3 (95% CI, 5.8-22.0). CONCLUSIONS: Offering FOBT kits during flu shot clinics dramatically increased the CRCS rate for flu shot clinic attendees. Pairing home FOBT kits with annual flu shots may be a useful strategy to improve CRCS rates in other primary care or public health settings.

Hepatitis B testing and vaccination among Vietnamese- and Cambodian-Americans.

We determined hepatitis B virus (HBV) testing and vaccination levels and factors associated with testing and vaccination among Vietnamese- and Cambodian-Americans. We also examined factors associated with healthcare professional (HCP)-patient discussions about HBV. We analyzed 2006 Racial and Ethnic Approaches to Community Health (REACH) 2010 Risk Factor Survey data from four US communities. We used logistic regression to identify variables associated with HBV vaccination, testing, and HCP-patient discussions about HBV. Of the 2,049 Vietnamese- and Cambodian-American respondents, 60% reported being tested for HBV, 35% reported being vaccinated against hepatitis B, and 36% indicated that they had discussed HBV with a HCP. Cambodian-Americans were less likely than Vietnamese-Americans to have been tested for HBV, while respondents with at least a high school diploma were more likely to have been tested for HBV. Respondents born in the US, younger individuals, and respondents with at least some college education were more likely to have been vaccinated against hepatitis B. HBV testing and vaccination remain suboptimal among members of these populations. Culturally sensitive efforts that target Vietnamese- and Cambodian-Americans for HBV testing and vaccination are needed to identify chronic carriers of HBV, prevent new infections, and provide appropriate medical management. HCPs that serve these populations should be encouraged to discuss HBV with their patients.

Healthy Colon, Healthy Life (Ruot Lành, Song Khoe): patient and physician factors associated with colorectal cancer screening among Vietnamese Americans in a county medical care system.

OBJECTIVE: To examine factors associated with colorectal cancer (CRC) screening among Vietnamese Americans. METHODS: Telephone survey of Vietnamese aged 50-79 receiving primary care at participating clinics. RESULTS: Among 808 participants, 53% were up to date (UTD) with fecal occult blood test (FOBT), 19% were UTD with sigmoidoscopy, 28% were UTD with colonoscopy. Females were more likely to be UTD with FOBT (OR 1.4, 95% CI 1.02, 1.93). Individuals in the U.S. for less than 15 years were less likely than others to be UTD with any CRC screening (OR 0.65, 95% CI 0.44, 0.96). Patients of female physicians were more likely to be UTD with sigmoidoscopy or colonoscopy (OR 1.72, 95% CI 1.15, 2.57). Ethnicity and language concordance were not associated with screening. CONCLUSIONS: Many Vietnamese people are not receiving CRC screening. Women and patients of female physicians receive more screening.

Cervical cancer control research in Vietnamese American communities.

Census data show that the U.S. Vietnamese population now exceeds 1,250,000. Cervical cancer among Vietnamese American women has been identified as an important health disparity. Available data indicate the cervical cancer disparity may be due to low Papanicolaou (Pap) testing rates rather than variations in human papillomavirus infection rates and/or types. The cervical cancer incidence rates among Vietnamese and non-Latina White women in California during 2000 to 2002 were 14.0 and 7.3 per 100,000, respectively. Only 70% of Vietnamese women who participated in the 2003 California Health Interview Survey reported a recent Pap smear compared with 84% of non-Latina White women. Higher levels of cervical cancer screening participation among Vietnamese women are strongly associated with current/previous marriage, having a usual source of care/doctor, and previous physician recommendation. Vietnamese language media campaigns and lay health worker intervention programs have been effective in increasing Pap smear use in Vietnamese American communities. Cervical cancer control programs for Vietnamese women should address knowledge deficits, enable women who are without a usual source of care to find a primary care doctor, and improve patient-provider communication by encouraging health-care providers to recommend Pap testing as well as by empowering women to ask for testing.

The Role of Physician Recommendation in Colorectal Cancer Screening Receipt Among Immigrant Chinese Americans.

Chinese Americans have low colorectal cancer (CRC) screening rates. It is unclear whether physicians should offer all CRC screening modalities (fecal occult blood test [FOBT], sigmoidoscopy, colonoscopy) to Chinese Americans to increase screening. Seven hundred and twenty-five Chinese Americans were asked in a survey if their physician had ever recommended CRC screening and to self-report receipt and type of CRC screening. Participants whose physician had recommended all CRC screening modalities were significantly more likely to report ever having screening (adjusted odds ratio 4.29, 95% CI 1.26-14.68) and being up-to-date (4.06, 95% CI 2.13-7.74) than those who reported that their physician only recommended FOBT. Participants who received a recommendation of only one type of screening did not report a significant difference in ever having or being up-to-date for screening. A potential strategy to increase CRC screening among Chinese Americans is for clinicians to recommend all available CRC screening modalities to each patient.
