Colorectal cancer is the second most common cause of cancer death in the United States, and rates of screening for colorectal cancer are low. We sought to gather the perceptions of clinic personnel at Latino-serving Federally Qualified Health Centers (operating 17 clinics) about barriers to utilization of screening services for colorectal cancer.
We conducted one-on-one interviews among 17 clinic personnel at four Latino-serving Federally Qualified Health Center networks in Oregon. All interviews were recorded, transcribed, and coded, and themes were grouped by influences at three levels: the patient, the organization, and the external environment.
Estimated proportions of eligible patients who are underscreened for colorectal cancer ranged from 20% to 70%. Underscreening was thought to occur among low-income, underinsured, and undocumented patients and patients having multiple health concerns. Limited funding to pay for follow-up testing in patients with positive screens was cited as the key factor contributing to underscreening.
We identified health care provider perceptions about the underutilization of screening services for colorectal cancer; our findings may inform future efforts to promote guideline-appropriate cancer screening.
Cervical cancer incidence rates vary substantially among racial/ethnic groups in the United States (US) with women of Southeast Asian descent having the highest rates. Up to 70% of cervical cancers could be prevented by widespread use of the human papillomavirus (HPV) vaccine. However, there is a lack of information about HPV vaccine uptake among Southeast Asian girls in the US. We conducted a telephone survey of Cambodian women with daughters who were age-eligible for HPV vaccination. Survey items addressed HPV vaccination barriers, facilitators, and uptake. Our study group included 86 Cambodian mothers who lived in the Seattle metropolitan area. The proportions of survey participants who reported their daughter had initiated and completed the HPV vaccine series were only 29% and 14%, respectively. Higher levels of vaccine uptake were significantly associated with mothers having heard about the HPV vaccine from a health professional and having received a recent Pap test. Commonly cited barriers to HPV vaccination included lack of knowledge about the HPV vaccine, not having received a physician recommendation for HPV vaccination, and thinking the HPV vaccine is unnecessary in the absence of health problems. Linguistically and culturally appropriate HPV educational programs should be developed and implemented in Cambodian American communities. These programs should aim to enhance understanding of disease prevention measures, increase knowledge about the HPV vaccine, and empower women to ask their daughters’ doctors for HPV vaccination.

Among caregivers of adolescent girls, awareness of human papillomavirus (HPV) is strongly associated with vaccine uptake. Little is known, however, about the predictors of HPV awareness among low-income ethnic minority groups in the U.S. The purpose of this study is to understand demographic factors associated with HPV awareness among low-income, ethnic minority mothers in Los Angeles County. We conducted a cross-sectional study of caregivers of adolescent girls through the Los Angeles County Department of Public Health Office of Women’s Health’s hotline. The majority of the participants were foreign-born (88%), one quarter lacked a usual source of care, and one quarter lacked public or private health insurance for their daughter. We found that one in three participants had never heard of HPV or the vaccine. Mothers that were unaware of HPV were significantly more likely to conduct the interview in a language other than English and to lack health insurance for their daughters. HPV vaccine awareness was much lower in our caregiver sample (61%) than in a simultaneous national survey of caregivers (85%). The associations between lack of awareness and use of a language other than English, as well as lack of health insurance for their daughter indicate the need for HPV vaccine outreach efforts tailored to ethnic minority communities in the U.S.

Hepatitis B infection is 5 to 12 times more common among Asian Americans than in the general US population and is the leading cause of liver disease and liver cancer among Asians. The purpose of this article is to describe the step-by-step approach that we followed in community-based participatory research projects in 4 Asian American groups, conducted from 2006 through 2011 in California and Washington state to develop theoretically based and culturally appropriate interventions to promote hepatitis B testing. We provide examples to illustrate how intervention messages addressing identical theoretical constructs of the Health Behavior Framework were modified to be culturally appropriate for each community.
Intervention approaches included mass media in the Vietnamese community, small-group educational sessions at churches in the Korean community, and home visits by lay health workers in the Hmong and Cambodian communities.
Use of the Health Behavior Framework allowed a systematic approach to intervention development across populations, resulting in 4 different culturally appropriate interventions that addressed the same set of theoretical constructs.
The development of theory-based health promotion interventions for different populations will advance our understanding of which constructs are critical to modify specific health behaviors.
Cambodian Americans have high rates of chronic hepatitis B virus (HBV) infection. However, only about one-half of Cambodian Americans have been serologically tested for HBV. We conducted a randomized controlled trial to evaluate the impact of a lay health worker (LHW) intervention on HBV testing and knowledge levels among Cambodian Americans. The study group included 250 individuals who participated in a community based survey in metropolitan Seattle and had not been tested for HBV. Experimental group participants received a LHW intervention addressing HBV and control group participants received a LHW intervention addressing physical activity. Trial participants completed a follow-up survey six months after randomization. Over four-fifths (82%) of randomized individuals participated in a LHW home visit and the follow-up survey response rate was 80%. Among participants with follow-up data, 22% of the experimental group and 3% of the control group reported HBV testing (p<0.001). The experimental and control group testing difference remained significant in an intent-to-treat analysis. The experimental group was significantly more likely than the control group to know that Cambodians have higher rates of HBV infection than whites, HBV cannot be spread by eating food prepared by an infected person, HBV cannot be spread by sharing chopsticks, and HBV cannot be spread by shaking hands. Our findings indicate LHW interventions are acceptable to Cambodian Americans and can positively impact both HBV testing and knowledge levels.

Chinese immigrants to North America experience cancer-related health disparities and underutilize preventive care. Little is known about Chinese immigrants' sources of health information.
A population-based survey of Chinese immigrants was conducted in Vancouver, British Columbia and Seattle, Washington.
The study group included 899 individuals. Less than three-quarters of the respondents reported receiving health information from healthcare providers and only a minority used the Internet as a source of health information. We found significant differences between the sources of health information in Seattle and Vancouver.
Health educators should consider available media outlets as well as the characteristics of a target community when planning intervention programs for Chinese immigrants.
Cambodian Americans have high rates of chronic hepatitis B virus (HBV) infection and liver cancer. There is very limited information about the utility of community health worker (CHW) approaches to cancer education for Asian American men. We have previously reported our positive findings from a trial of CHW education about HBV for Cambodian Americans who had never been tested for HBV. This report describes similarities and differences between the outcomes of our CHW HBV educational intervention among Cambodian American men and women.
The study group for this analysis included 87 individuals (39 men and 48 women) who were randomized to the experimental (HBV education) arm of our trial, participated in the CHW educational intervention, and provided follow-up data six months post-intervention. We examined HBV testing rates at follow-up, changes in HBV-related knowledge between baseline and follow-up, and barriers to HBV testing (that were reported to CHWs) by gender.
At follow-up, 15% of men and 31% of women reported they had received a HBV test (p=0.09). HBV-related knowledge levels increased significantly among both men and women. With respect to HBV testing barriers, women were more likely than men to cite knowledge deficits, and men were more likely than women to cite logistic issues.
Our study findings indicate that CHW interventions can positively impact knowledge among Cambodian American men, as well as women. They also suggest CHW interventions may be less effective in promoting the use of preventive procedures by Cambodian American men than women. Future CHW research initiatives should consider contextual factors that may differ by gender and, therefore, potentially influence the relative effectiveness of CHW interventions for men versus women.

Cervical cancer occurs more frequently among Vietnamese Americans than women of any other race/ethnicity. In addition, previous studies in California have documented low Papanicolaou (Pap) testing rates in Vietnamese communities. This study focused on health care system factors and physician characteristics associated with recent cervical cancer screening among Vietnamese women. A population-based survey was conducted in Seattle during 2002. In-person interviews were conducted by bilingual, bicultural female survey workers. The survey response rate was 82% and 518 women were included in the analysis. Seventy-four percent of the respondents reported having been screened for cervical cancer on at least one occasion, and 64% reported a Pap smear within the previous 2 years. Women with a regular doctor were more likely to have been recently screened than those without a regular doctor (OR = 2.33, 95% CI = 1.45–3.74). Among those with a regular doctor, having a male physician, receiving care at a private doctor’s office (rather than a community, hospital, or multi-specialty clinic), and concern about the cost of health care were independently associated with lower screening rates. Physician ethnicity was not associated with recent Pap smear receipt. The findings support targeted interventions for Vietnamese women without a regular physician and private doctors’ offices that serve Vietnamese Americans. The availability of low cost screening services should be publicized in Vietnamese communities.

Chinese American immigrants are a growing part of the United States population. Cervical cancer is a significant cause of morbidity and mortality among Chinese Americans. Pap smear testing is less common in Chinese American immigrants than in the general population. During 1999, we conducted a community-based survey of Chinese American women living in Seattle. We assessed knowledge of cervical cancer risk factors and history of Pap smear testing along with socioeconomic and acculturation characteristics. The overall estimated response rate was 64%, and the cooperation rate was 72%. Our study sample included 472 women. Most cervical cancer risk factors were recognized by less than half of our participants. Factors independently associated with knowledge of cervical cancer risk factors included marital status, employment, and education. Respondents with the highest knowledge had greater odds of ever receiving a Pap smear, compared to those respondents with the lowest knowledge (OR 2.5; 95% CI: 1.1,5.8). Our findings suggest a need for increased recognition of cervical cancer risk factors among Chinese American immigrants. Culturally and linguistically appropriate educational interventions for cervical cancer risk factors should be developed, implemented and evaluated.

We examined levels of Pap testing and factors associated with screening participation among Cambodian refugees.
A community-based, in-person survey was conducted in Seattle during late 1997 and early 1998. Interviews were completed by 413 women; the estimated response rate was 73%. We classified respondents into four Pap testing stages of adoption: precontemplation/contemplation (never screened), relapse (ever screened but did not plan to be screened in the future), action (ever screened and planned to be screened in the future), and maintenance (recently screened and planned to be screened in the future). Bivariate and multivariate techniques were used to examine various factors.
About one-quarter (24%) of the respondents has never been screened, and a further 22% had been screened but did not plan to obtain Pap tests in the future. Fifteen percent were in the action stage and 39% were in the maintenance stage. The following factors were independently associated with cervical cancer screening stages: previous physician recommendation; younger age; beliefs about Pap testing for post-menopausal women, screening for sexually inactive women, and regular checkups; provider ethnicity; prenatal care in the US; and problems finding interpreters.
Our findings confirm low Pap testing rates among Cambodian immigrants, and suggest that targeted interventions should be multifaceted.
North American Chinese women have lower levels of Papanicolaou (Pap) testing than other population subgroups. We conducted a randomized controlled trial to evaluate the effectiveness of two alternative cervical cancer screening interventions for Chinese women living in North America.
Four hundred and eighty-two Pap testing underutilizers were identified from community-based surveys of Chinese women conducted in Seattle, Washington, and Vancouver, British Columbia. These women were randomly assigned to one of two experimental arms or control status. Several Chinese-language materials were used in both experimental arms: an education-entertainment video, a motivational pamphlet, an educational brochure, and a fact sheet. Women in the first experimental group (outreach worker intervention) received the materials, as well as tailored counseling and logistic assistance, during home visits by trilingual, bicultural outreach workers. Those in the second experimental group (direct mail intervention) received the materials by mail. The control group received usual care. Follow-up surveys were completed 6 months after randomization to ascertain participants’ Pap testing behavior. All statistical tests were two-sided.
A total of 402 women responded to the follow-up survey (83% response rate). Of these women, 50 (39%) of the 129 women in the outreach group, 35 (25%) of the 139 women in the direct mail group, and 20 (15%) of the 134 women in the control group reported Pap testing in the interval between randomization and follow-up data collection (P<.001 for outreach worker versus control, P = .03 for direct mail versus control, and P = .02 for outreach worker versus direct mail). Intervention effects were greater in Vancouver than in Seattle.
Culturally and linguistically appropriate interventions may improve Pap testing levels among Chinese women in North America.
Southeast Asians have higher liver cancer rates than any other racial/ethnic group in the US. Approximately 80 percent of liver cancers are etiologically associated with hepatitis B virus (HBV) infection which is endemic in Southeast Asia. An in-person survey of Cambodian women (n = 320) was conducted in Seattle, Washington, during 1999. The questionnaire included items about HBV knowledge, beliefs, and practices. Prior to being provided with a description of the disease, only about one-half (56 percent) of our respondents had heard of HBV infection. Less than one-quarter (23 percent) of the study group thought that asymptomatic individuals can transmit the disease to others. Most thought that HBV infection can cause liver cancer (54 percent) and death (72 percent). However, a minority thought that infection can be lifelong (24 percent) and incurable (15 percent). Only 38 percent reported they had been serologically tested for HBV. Finally, of those who had been tested and thought they were susceptible, two-thirds (67 percent) had not been vaccinated. Lower levels of education were associated with lower levels of HBV knowledge and serologic testing. Our findings suggest that Cambodian immigrants have low levels of HBV knowledge, serologic testing, and vaccination; and demonstrate a need for targeted educational interventions aimed at reducing HBV-related liver cancer mortality among Southeast Asian communities.

Available data indicate that Asian Americans as a group have lower levels of physical activity than non-Latino whites. However, few studies have focused on physical activity among Asian American sub-groups. Our objectives were to describe levels of physical activity, as well as individual and environmental correlates of physical activity among Cambodian Americans.
We conducted a telephone survey of Cambodians living in three geographic areas (Central California, Northern California, and the Pacific Northwest) during 2010. Physical activity levels were assessed using the International Physical Activity Questionnaire (IPAQ) short version. Survey items addressed demographic characteristics, knowledge about the health benefits of physical activity, social norms and supports with respect to physical activity, the availability of neighbourhood recreational facilities, and neighbourhood characteristics.
Our study group included 222 individuals. Only 12% of the study group reported low levels of physical activity, 40% reported moderate levels, and 48% reported high levels. Physical activity was strongly associated with the availability of neighborhood recreational facilities such as parks, but not with neighborhood characteristics such as heavy traffic.
Our results suggest that a majority of Cambodian Americans are adherent to current physical activity guidelines. Neighborhood recreational facilities that provide opportunities for leisure-time physical activity are associated with higher levels of physical activity in Cambodian communities. Future research should assess the reliability and validity of the IPAQ in a Cambodian American study group.

Women of Southeast Asian descent have higher cervical cancer incidence rates than any other group. Widespread use of HPV vaccination could prevent up to 70% of cervical cancers. There is little published information addressing HPV vaccination uptake among Asian Americans. We conducted a survey of Cambodian women with daughters who were age-eligible for HPV vaccination. Survey items addressed HPV vaccination barriers, facilitators, and uptake. Only 26% of the survey participants reported any of their age-eligible daughters had received vaccination, and only 40% reported a previous physician recommendation for vaccination. Higher levels of vaccine uptake were strongly associated with having received a doctor's recommendation for vaccination (P<0.001) and having asked a doctor for vaccination (p=0.002). HPV vaccine uptake was relatively low in our Cambodian study group. Educational initiatives should encourage health care providers who serve Cambodian families to recommend HPV vaccination and empower Cambodian mothers to ask their daughters' doctors for vaccination.
Cambodian Americans have an elevated risk of liver cancer. This health disparity is attributable to high rates of hepatitis B virus (HBV) infection. Our study examined factors associated with HBV testing among Cambodian men and women.
A population-based survey was conducted in the Seattle area. The Health Behavior Framework guided our survey instrument development. We attempted to interview a man and a woman in each household.
The sample included 300 men and 367 women. About one-half of the male (45%) and female (54%) respondents had been tested for HBV. Two factors were independently associated with testing among men and women: a doctor had recommended testing and had asked a doctor for testing. Knowing that someone who looks and feels healthy can spread HBV was independently associated with testing among men.
Low levels of HBV testing remain a public health problem among Cambodians. Interventions should improve patient-provider communication by encouraging providers who serve Cambodians to recommend HBV testing, as well as by empowering Cambodians to ask for testing.

Hepatocellular cancer occurs more frequently among Koreans, Vietnamese, and Chinese than other racial/ethnic groups in the U.S. This excess risk can be attributed to high rates of chronic hepatitis B viral (HBV) infection and low rates of HBV vaccination among Asian immigrants. However, there is little available information regarding the hepatitis B knowledge, beliefs, and practices among Koreans, the fifth-largest Asian population in the U.S. This brief report summarizes results from 30 qualitative interviews and two focus groups investigating hepatitis and liver cancer prevention, behavior, and beliefs among first-generation Korean immigrant adults ages 18–64 years residing in the Seattle–Tacoma metropolitan area of Washington State. The report concludes with suggestions for future investigations to address the high rates of chronic HBV infection and hepatocellular cancer in this vulnerable population.

The introduction of HPV vaccines represents a breakthrough in the primary prevention of cervical cancer. However, little is known about vaccination uptake and correlates among U.S. low-income, ethnic minority and immigrant populations who may benefit most from the vaccine.
Telephone interviews (N=490) were conducted in six languages between January and November 2009 among mothers of vaccine-eligible girls (ages 9–18) using the Los Angeles County Department of Public Health, Office of Women’s Health service referral hotline. HPV and vaccine awareness, knowledge, beliefs, barriers, and daughter’s vaccine receipt were assessed.
The sample consisted of low-income, uninsured, ethnic minority and immigrant women. Only 29% of daughters initiated the vaccine and 11% received all three doses. No ethnic differences were observed in initiation or completion rates. Ethnic differences were observed in HPV awareness, perceived risk, and other immunization related beliefs. The strongest predictor of initiation was vaccine awareness (OR=12.00). Daughter’s age and reporting a younger acceptable age for vaccination were positively associated with initiation. Mothers of unvaccinated girls reported lacking information about the vaccine to make a decision (66%) and not knowing where they could obtain the vaccine (74%).
Vaccination rates in this sample were lower than state and national estimates, and were associated with low levels of vaccine awareness. Interventions, including culturally targeted messaging, may be helpful for enhancing HPV vaccine knowledge, modifying vaccine-related beliefs and increasing uptake.
Our findings provide valuable guidance for developing interventions to address sub-optimal HPV vaccination in high risk groups.

Regular physical activity produces various health benefits; however, relatively few adults in the United States (US) get enough physical activity. Little is known about physical activity behaviors, and barriers and facilitators to physical activity among Cambodian-Americans. Cambodian Americans were recruited from community venues to participate in one-on-one interviews and focus groups. A total of 20 adults (10 women and 10 men) participated in one-on-one interviews and 37 adults (23 women and 14 men) participated in one of four focus groups. Fifteen of the 20 interviews and all the focus groups were conducted in Khmer. Participants were generally born in Cambodia and over two-thirds had a high school education or less. About one-half of the participants met or exceeded the 2008 US Department of Health and Human Services physical activity guidelines. Commonly reported types of physical activity were walking, running, and working out at the gym. Barriers to physical activity included lack of time, inconvenient work hours, and family responsibilities. Perceived benefits of physical activity included improved health, improved appearance, and reductions in stress. Sweating caused by physical activity was thought to produce a variety of health benefits. Data from this qualitative study could be used to inform the development of culturally-relevant physical activity survey measures and culturally-relevant physical activity interventions for Cambodian Americans.

Surname lists are increasingly being used to identify Asian study participants. Two Vietnamese surname lists have previously been published: the Vietnamese Community Health Promotion Program (VCHPP) list and the Lauderdale list. This report provides findings from a descriptive analysis of the performance of these lists in identifying Vietnamese. To identify participants for a survey of Vietnamese women, a surname list (that included names that appear on the VCHPP list and/or Lauderdale list) was applied to the Seattle telephone book. We analyzed surname data for all addresses in the survey sample, as well as survey respondents. The VCHPP list identified 4,283 potentially Vietnamese households, and 79% of the households with established ethnicity were Vietnamese; and the Lauderdale list identified 4,068 potentially Viet-namese households, and 80% of the households with established ethnicity were Vietnamese. However, the proportions of contacted households that were Vietnamese varied significantly among commonly occurring surnames. The characteristics of women with surnames on the VCHPP and Lauderdale lists were equivalent. The two lists performed equally well in identifying Vietnamese households. Researchers might consider using different combinations of Vietnamese surnames, depending on whether accuracy or high population coverage is the more important consideration.

Liver cancer occurs more frequently among Americans of Southeast Asian descent than any other group. This health disparity can be attributed to high rates of hepatitis B virus (HBV) infection. We examined HBV awareness, knowledge about HBV transmission, HBV testing levels, and HBV vaccination levels among Cambodian Americans.
A population-based survey was conducted in metropolitan Seattle during 2010. The study sample included 667 individuals. We created a composite knowledge score (0–9) by summing the number of correct answers to survey items addressing HBV transmission. Data were analyzed using Generalized Estimating Equations.
Seventy-eight percent of the study group had heard of HBV (before it was described to them). The proportions who knew that HBV cannot be spread by eating food prepared by an infected person, can be spread during childbirth, and can be spread during sexual intercourse were only 33%, 69%, and 72%, respectively. The mean knowledge score was 5.5 (standard deviation 1.7). Fifty percent of the survey respondents had been tested and 52% had been vaccinated. HBV awareness, higher knowledge scores, and vaccination were all associated (p<0.05) with younger age, higher educational level, younger age at immigration, and greater English proficiency.
Our study findings confirm the need for Khmer language HBV programs for less acculturated and educated members of the Cambodian community. Such programs should aim to increase HBV testing rates, HBV vaccination rates among individuals who remain susceptible to infection, and levels of knowledge about routes of hepatitis B transmission.

We conducted a trial to evaluate the effectiveness of a cervical cancer control intervention for Vietnamese women.
The study group included 234 women who had not received a Pap test in the last three years. Experimental group participants received a lay health worker home visit. Our trial end-point was Pap smear receipt within six months of randomization. Pap testing completion was ascertained through women's self-reports and medical record reviews. We examined intervention effects among women who had ever received a Pap smear (prior to randomization) and women who had never received a Pap smear.
Three-quarters of the experimental group women completed a home visit. Ever screened experimental group women were significantly more likely to report Pap testing (p<0.02) and have records verified Pap testing (p<0.04) than ever screened control group women. There were no significant differences between the trial arms for women who had never been screened.
Our findings indicate that lay health worker interventions for Vietnamese women are feasible to implement and can positively impact levels of Pap testing use among ever screened women (but not never screened women).

To conduct a randomized controlled trial to evaluate the cost effectiveness of a lay health worker-administered cervical cancer screening intervention for Vietnamese-American women.
The study group included 234 Vietnamese women in the Seattle, Washington area who had not received a Pap test in the last three years. Experimental group participants received a lay health worker home visit. The travel distance and time spent at each visit were recorded. Our trial end-point was Pap smear receipt within six months of randomization. Pap testing completion was ascertained through medical record reviews.
For all Vietnamese women, regardless of their prior history of screening, the cost per intervention was $104.0 (95% CI: $89.6–$118.4). The change in quality-adjusted life days per intervention was 1.26 (95% CI: −5.43–7.96), resulting in an incremental cost-effectiveness ratio (ICER) of $30,015 per quality-adjusted life year. The probability that the ICER exceeds $100,000 is 9.1%.
The degree of cost effectiveness of such interventions is sensitive to the assumed duration of behavioral change and the participants’ prior history of screening.

Asian immigrants to the U.S. have an increased prevalence of hepatitis B virus (HBV) infection compared to native born individuals; an estimated 10 percent of Chinese immigrants are infected with HBV. Using qualitative data from focus groups, we developed an English-as-a-Second Language (ESL) curriculum that aimed to improve knowledge about key hepatitis B facts. The curriculum was pilot-tested among 56 students aged 50 and older from intermediate-level ESL classes at a community-based organization that serves Chinese immigrants. Post-curriculum data showed increases in knowledge that hepatitis B can cause liver cancer (73% at pre-test vs. 91% at post-test; p value = 0.01) and that individuals can be infected with hepatitis B for life (34% vs. 81%; p value <0.0001). These findings suggest that an ESL curriculum can successfully improve knowledge about the severity of hepatitis B and its routes of transmission among older Chinese American adults.

Recent US data indicate that women of Vietnamese descent have higher cervical cancer incidence rates than women of any other race/ethnicity, and lower levels of Pap testing than white, black, and Latina women. Our objective was to provide information about Pap testing barriers and facilitators that could be used to develop cervical cancer control intervention programs for Vietnamese American women.
We conducted a cross-sectional, community-based survey of Vietnamese immigrants. Our study was conducted in metropolitan Seattle, Washington. A total of 1,532 Vietnamese American women participated in the study. Demographic, health care, and knowledge/belief items associated with previous cervical cancer screening participation (ever screened and screened according to interval screening guidelines) were examined.
Eighty-one percent of the respondents had been screened for cervical cancer in the previous three years. Recent Pap testing was strongly associated (p<0.001) with having a regular doctor, having a physical in the last year, previous physician recommendation for testing, and having asked a physician for testing. Women whose regular doctor was a Vietnamese man were no more likely to have received a recent Pap smear than those with no regular doctor.
Our findings indicate that cervical cancer screening disparities between Vietnamese and other racial/ethnic groups are decreasing. Efforts to further increase Pap smear receipt in Vietnamese American communities should enable women without a source of health care to find a regular provider. Additionally, intervention programs should improve patient-provider communication by encouraging health care providers (especially male Vietnamese physicians serving women living in ethnic enclaves) to recommend Pap testing, as well as by empowering Vietnamese women to specifically ask their physicians for Pap testing.

The cervical cancer incidence rate among Cambodian American women is 15.0 per 100,000, compared to 7.7 per 100,000 among non-Latina white women. HPV infection has been identified as a universal risk factor for cervical cancer. The HPV vaccine was recently approved in the United States for females aged 9–26 years. There is little information about HPV vaccination knowledge and beliefs in Southeast Asian communities.
We conducted 13 key informant interviews with Cambodian community leaders, as well as four focus groups with Cambodian parents (37 participants). Two of the focus groups included fathers and two of the focus groups included mothers. Interview and focus group questions addressed HPV vaccine barriers and facilitators.
Participants had limited knowledge about HPV infection and the HPV vaccine. Barriers to HPV vaccination included a lack of information about the vaccine, as well as concerns about vaccine safety, effectiveness, and financial costs. The most important facilitators were a health care provider recommendation for vaccination and believing in the importance of disease prevention.
Future cervical cancer control educational programs for Cambodians should promote use of the HPV vaccine for age-eligible individuals. Health care providers who serve Cambodian communities should be encouraged to recommend HPV vaccination.
