Colorectal cancer beliefs, knowledge, and screening among Filipino, Hmong, and Korean Americans.

To the authors' knowledge, there are few studies to date regarding colorectal cancer (CRC) beliefs, knowledge, and screening among multiple Asian American populations, who are reported to have lower CRC screening rates compared with white individuals. The current study was performed to assess knowledge and beliefs regarding the causes of CRC, its prevention, and factors associated with CRC screening among 3 Asian American groups. The authors conducted an in-language survey with Filipino (Honolulu, Hawaii), Hmong (Sacramento, California), and Korean (Los Angeles, California) Americans aged 50 to 75 years who were sampled through social networks. Bivariate and multivariable analyses were conducted to assess factors associated with CRC screening. The sample of 981 participants was 78.3% female and 73.8% reported limited proficiency in English. Few of the participants were aware that age (17.7%) or family history (36.3%) were risk factors for CRC; 6.2% believed fate caused CRC. Only 46.4% of participants knew that screening prevented CRC (74.3% of Filipino, 10.6% of Hmong, and 55.8% of Korean participants; P<.001). Approximately two-thirds of participants reported ever having undergone CRC screening (76.0% of Filipino, 72.0% of Hmong, and 51.4% of Korean participants; P<.001) and 48.6% were up to date for screening (62.2% of Filipino, 43.8% of Hmong, and 41.4% of Korean participants; P<.001). Factors found to be significantly associated with ever screening were being Korean (compared with Filipino), having a family history of CRC, having health insurance or a regular source of health care, and knowing that a fatty diet caused CRC. Believing that fate caused CRC and that praying prevented it were found to be negatively associated with ever screening. Factors associated with being up to date for CRC screening included being born in the United States, having a family history of CRC, and having access to health care. Knowledge regarding the causes of CRC and its prevention among Filipino, Hmong, and Korean individuals is low. However, health care access, not knowledge or beliefs, was found to be a key determinant of CRC screening. Cancer 2018;124:1552-9. © 2018 American Cancer Society.

Knowledge of colorectal cancer screening guidelines and intention to obtain screening among nonadherent Filipino, Hmong, and Korean Americans.

Nonadherence to colorectal cancer (CRC) screening among Asian Americans is high but not well understood. This study examined correlates of screening intention among Filipino, Hmong, and Korean Americans who were nonadherent to CRC screening. Using cross-sectional, preintervention survey data from 504 Asian Americans (115 Filipinos, 185 Hmong, and 204 Koreans) aged 50-75 years who were enrolled in a multisite cluster randomized controlled trial of lay health educator intervention, we analyzed correlates of self-reported CRC screening nonadherence, which was defined as not being up-to-date for fecal occult blood test, sigmoidoscopy, or colonoscopy. Only 26.8% of participants indicated intention to obtain screening within 6 months (Hmong: 12.4%; Korean: 30.8%; and Filipino: 42.6%; P < .001). Only one third of participants had undergone a prior screening, and a majority did not know that screening is a method of CRC prevention method (61.3%) or had any knowledge of CRC screening guidelines (53.4%). Multivariable analyses revealed that patient-provider ethnicity concordance, provider's recommendation of screening, participants' prior CRC screening, perceived severity and susceptibility of CRC, and knowledge of guidelines were positively associated with screening intention. Specifically, knowing one or more screening guidelines doubled the odds of screening intention (adjusted odds ratio, 2.38; 95% confidence interval, 1.32-4.28). Hmong were less likely to have screening intention than Filipinos, which was unexplained by socio-demographics, health care factors, perceived needs for CRC screening, or knowledge of screening guidelines. CRC screening intention among nonadherent Filipino, Hmong, and Korean Americans was low. Targeting knowledge of CRC screening guidelines may be effective strategies for increasing CRC screening intention among nonadherent Asian Americans.

Lay health educators increase colorectal cancer screening among Hmong Americans: A cluster randomized controlled trial.

Asian Americans have lower colorectal cancer (CRC) screening rates than non-Hispanic white individuals. Hmong Americans have limited socioeconomic resources and literacy. The current randomized controlled trial was conducted to determine whether bilingual/bicultural lay health educator (LHE) education could increase CRC screening among Hmong Americans. A cluster randomized controlled trial was conducted among Hmong Americans in Sacramento, California. LHEs and recruited participants were randomized to intervention or control groups. The intervention group received CRC education over 3 months delivered by an LHE. The control group received education regarding nutrition and physical activity delivered by a health educator. The outcomes were changes in self-reported ever-screening and up-to-date CRC screening after 6 months. All 329 participants were foreign-born with mostly no formal education, limited English proficiency, and no employment. The majority of the participants were insured and had a regular source of health care. The intervention group experienced greater changes after the intervention than the control group for ever-screening (P = .068) and being up-to-date with screening (P<.0001). In multivariable regression analyses, the intervention group demonstrated a greater increase than the control group in reporting ever-screening (adjusted odds ratio, 1.73; 95% confidence interval, 1.07-2.79) and being up-to-date with screening (adjusted odds ratio, 1.71; 95% confidence interval, 1.26-2.32). Individuals who had health insurance were found to have >4 times the odds of receiving screening, both ever-screening and up-to-date screening. A higher CRC knowledge score mediated the intervention effect for both screening outcomes. A culturally and linguistically appropriate educational intervention delivered by trained LHEs was found to increase CRC screening in an immigrant population with low levels of education, employment, English proficiency, and literacy.

Results of a lay health education intervention to increase colorectal cancer screening among Filipino Americans: A cluster randomized controlled trial.

Filipino colorectal cancer (CRC) screening rates fall below Healthy People 2020 goals. In this study, the authors explore whether a lay health educator (LHE) approach can increase CRC screening among Filipino Americans ages 50 to 75 years in Hawai'i. A cluster randomized controlled trial from 2012 through 2015 compared an intervention, which consisted of LHEs delivering 2 education sessions and 2 telephone follow-up calls on CRC screening plus a CRC brochure versus an attention control, in which 2 lectures and 2 follow-up calls on nutrition and physical activity plus a CRC brochure were provided. The primary outcome was change in self-reported ever receipt of CRC screening at 6 months. Among 304 participants (77% women, 86% had > 10 years of residence in the United States), the proportion of participants who reported ever having received CRC screening increased significantly in the intervention group (from 80% to 89%; P = .0003), but not in the control group (from 73% to 74%; P = .60). After covariate adjustment, there was a significant intervention effect (odds ratio, 1.9; 95% confidence interval, 1.0-3.5). There was no intervention effect on up-to-date screening. This first randomized controlled trial for CRC screening among Hawai'i's Filipinos used an LHE intervention with mixed, but promising, results.
