Demographic predictors of cancer screening among Filipino and Korean immigrants in the United States.

BACKGROUND Little is known about cancer-screening practices of various Asian subgroups, and even less is known about factors that may predict screening in these populations. DESIGN Two independent surveys were conducted with 218 Filipino and 229 Korean female immigrants, aged 50 years and older, residing in Los Angeles. RESULTS In these convenience samples, 48% of Filipino and 41% of Korean women reported receipt of a Pap smear within the past 2 years; 41% of Filipino and 25% of Korean women reported receipt of a mammogram and a clinical breast exam within the past 2 years; and 25% of Filipino and 38% of Korean women reported colorectal cancer screening (blood stool test within the past 12 months or sigmoidoscopy/colonoscopy within the past 5 years). Only 14% of Filipino and 10% of Korean women were adherent to cancer-screening guidelines for all three sites. These differences in screening rates were statistically significant in multivariate analyses of the combined sample, controlling for all demographic characteristics, including age, percent of lifetime in the United States, education, marital status, health insurance, employment, and ethnicity. The two variables that were most consistently independently associated with adherence to cancer screening in both samples were higher percentage of lifetime spent in the United States and ever having had a checkup when no symptoms were present. CONCLUSIONS These two variables-percent of lifetime in the United States and ever having had a checkup when no symptoms were present-can alert a physician that cancer-screening tests may be overdue among Korean and Filipino immigrants in the United States. Future research should identify predictors of cancer screening among other Asian immigrant groups and U.S.-born Asian women to assist in targeting intervention efforts.

Food consumption frequency and perceived stress and depressive symptoms among students in three European countries

BackgroundCertain foods might be more frequently eaten under stress or when higher levels of depressive symptoms are experienced. We examined whether poor nutritional habits are associated with stress and depressive symptoms and whether the relationships differ by country and gender in a sample from three European countries collected as part of a Cross National Student Health Survey.MethodsA cross-sectional survey was conducted among first-year students in Germany (N = 696), Poland (N = 489) and Bulgaria (N = 654). Self-administered questionnaires included a 12-item food frequency questionnaire, Cohens Perceived Stress Scale, and a modified Beck Depression Index. Linear regression analyses were conducted for two outcomes, perceived stress and depressive symptoms.ResultsFood consumption frequencies differed by country and gender, as did depressive symptoms and perceived stress. For male students, none of the food consumption groups were associated with perceived stress or depressive symptoms. In females, perceived stress was associated with more frequent consumption of sweets/fast foods and less frequent consumption of fruits/vegetables. Additionally, depressive symptoms were associated with less frequent consumption of fruits/vegetables and meat.ConclusionOur data show consistent associations between unhealthy food consumption and depressive symptoms and perceived stress among female students from three European countries, but not among male students. This suggests that efforts to reduce depressive symptoms and stress among female students may also lead to the consumption of healthier foods and/or vice-versa.

Sociodemographic predictors of non-attendance at invitational mammography screening: a population-based register study (Sweden)

Objective: To investigate the role of sociodemographic factors in predicting mammography uptake in an outreach screening program. Methods: Linkage of data from a regional population-based mammography program with four Swedish nationwide registers: the Population and Housing Census of 1990, the Fertility Register, the Cancer Register, and the Cause of Death Register. We computed odds ratios (OR) and 95% confidence intervals (CI) for non-attendance by sociodemographic factors. Non-attendance was defined as failure to attend in response to the two most recent invitations. Results: Multivariate analyses among 4198 non-attenders and 38,972 attenders revealed that both childless and high-parity women were more likely to be non-attenders (OR = 1.8, 95% CI: 1.6–2.0 and OR = 2.2, 95% CI: 1.8–2.7, respectively). Women living without a partner were less likely to attend (OR = 1.7, 95% CI: 1.5–1.9), as were non-employed women (OR = 2.1, 95% CI: 1.9–2.3). Those renting an apartment were more likely to be non-attenders compared with home-owners (OR = 1.8, 95% CI: 1.6–2.0), and immigrants from non-Nordic countries were more than twice as likely to be non-attenders compared with Swedish-born women (OR = 2.4, 95% CI: 2.0–2.8). Conclusions: There are identifiable subgroups in which mammography utilization can be increased. Special attention should be paid to women who have never attended, childless women, and non-Nordic immigrants.

Colorectal cancer screening among underserved Korean Americans in Los Angeles County.

ObjectivesUse of colorectal cancer screening is extremely low among Korean Americans. The objective of this study was to gather information on predictors, facilitators, barriers, and intervention preferences with respect to colorectal cancer screening that may inform the development of future interventions for underserved Korean Americans.DesignWe developed a questionnaire guided by the Health Behavior Framework and administered it to a convenience sample of 151 Korean Americans aged 40–70 recruited through a community based organization in Los Angeles.ResultsIn our sample in which 60% of the subjects did not have health insurance, only 17% reported having received a stool blood test within the past year or sigmoidoscopy or colonoscopy within the past 5 years. Having received a physician recommendation was significantly associated and having symptoms of the disease was marginally associated with the outcome variable. Although 64% of respondents reported having a primary care physician, only 29% received a screening recommendation from a physician. Barriers to colorectal cancer screening were lack of health insurance and inability to afford testing, not knowing where to go for testing, language barrier, and fear of being a burden to the family. Intervention preferences included educational seminars, media campaigns, and print materials.ConclusionOur findings point to the need for a multi-faceted approach that includes educational seminars at community venues, a media campaign, and physician education to increase colorectal cancer screening in this underinsured Korean American population.

Correlates of depressive symptoms among Latino and Non-Latino White adolescents: Findings from the 2003 California Health Interview Survey

BackgroundThe prevalence of depression is increasing not only among adults, but also among adolescents. Several risk factors for depression in youth have been identified, including female gender, increasing age, lower socio-economic status, and Latino ethnic background. The literature is divided regarding the role of acculturation as risk factor among Latino youth. We analyzed the correlates of depressive symptoms among Latino and Non-Latino White adolescents residing in California with a special focus on acculturation.MethodsWe performed an analysis of the adolescent sample of the 2003 California Health Interview Survey, which included 3,196 telephone-interviews with Latino and Non-Latino White adolescents between the ages of 12 and 17. Depressive symptomatology was measured with a reduced version of the Center for Epidemiologic Studies Depression Scale. Acculturation was measured by a score based on language in which the interview was conducted, language(s) spoken at home, place of birth, number of years lived in the United States, and citizenship status of the adolescent and both of his/her parents, using canonical principal component analysis. Other variables used in the analysis were: support provided by adults at school and at home, age of the adolescent, gender, socio-economic status, and household type (two parent or one parent household).ResultsUnadjusted analysis suggested that the risk of depressive symptoms was twice as high among Latinos as compared to Non-Latino Whites (10.5% versus 5.5 %, p < 0.001). The risk was slightly higher in the low acculturation group than in the high acculturation group (13.1% versus 9.7%, p = 0.12). Similarly, low acculturation was associated with an increased risk of depressive symptoms in multivariate analysis within the Latino subsample (OR 1.54, CI 0.97–2.44, p = 0.07). Latino ethnicity emerged as risk factor for depressive symptoms among the strata with higher income and high support at home and at school. In the disadvantaged subgroups (higher poverty, low support at home and at school) Non-Latino Whites and Latinos had a similar risk of depressive symptoms.ConclusionOur findings suggest that the differences in depressive symptoms between Non-Latino Whites and Latino adolescents disappear at least in some strata after adjusting for socio-demographic and social support variables.

Results of a randomized trial to increase breast and cervical cancer screening among Filipino American women

BACKGROUND This paper reports the first evaluation of an intervention to increase breast and cervical cancer screening among Filipino American women. METHODS Filipino women over 40 years of age were recruited through nine community-based organizations and six churches in Los Angeles County. After completion of a short baseline interview, all women were invited to attend a group session with some of their peers and a female Filipino health educator. Women within each organization were randomized to receive a cancer screening module (intervention) or a physical activity module (control). Telephone follow-up interviews 12 months after the group session assessed the impact of the intervention. RESULTS Of the 530 women invited, 444 (84%) attended a session. At baseline and follow-up, screening rates for breast and cervical cancer did not differ between study groups. Moderate increases in screening rates (9 to 12 percentage points) were observed in both arms of the study. Among relatively recent immigrants who had spent less than 10 years in the United States, mammography screening increased substantially more in the intervention arm than under the control condition (a 27 vs 6 percentage point increase, P<0.05). CONCLUSION Our intervention was only effective in increasing cancer screening among relatively recent immigrants who had very low baseline screening rates.

Trends in Colorectal Cancer Screening Utilization among Ethnic Groups in California: Are We Closing the Gap?

Background: Given the low prevalence of and racial/ethnic disparities in colorectal cancer screening, it is important to monitor whether prevalence and disparities are increasing or decreasing over time. Methods: We estimated the prevalence of colorectal cancer screening by year (2001, 2003, and 2005), modality (endoscopy, fecal occult blood test, either), and recency (ever had, up-to-date) for the California population as a whole, major racial/ethnic groups (White, Black, Latino, Asian), and selected Asian subgroups (Chinese, Filipino, Japanese, Korean, Vietnamese) using data from the California Health Interview Survey. All prevalence estimates were age- and gender-standardized. Results: From 2001 to 2005, prevalence of up-to-date screening increased significantly among Whites and Latinos but not among Blacks and Asian Americans. Screening prevalence varied substantially among Asian subgroups, with Korean, Filipino, and Vietnamese Americans having the lowest prevalence. Korean Americans were the only group in the analysis with a significant decline in screening prevalence from 2001 to 2005. The gap between the highest and the lowest up-to-date screening prevalence using any screening modality, exhibited by Japanese and Korean Americans, increased from 18% in 2001 to 30% in 2005. Conclusions: Findings suggest that we need to intensify efforts to increase colorectal cancer screening, especially among Korean Americans but also among Filipinos, Vietnamese, and Latinos.

Explaining disparities in colorectal cancer screening among five Asian ethnic groups: A population-based study in California

BackgroundData from the California Health Interview Survey (CHIS) indicate that levels and temporal trends in colorectal cancer (CRC) screening prevalence vary among Asian American groups; however, the reasons for these differences have not been fully investigated.MethodsUsing CHIS 2001, 2003 and 2005 data, we conducted hierarchical regression analyses progressively controlling for demographic characteristics, English proficiency and access to care in an attempt to identify factors explaining differences in screening prevalence and trends among Chinese, Filipino, Vietnamese, Korean and Japanese Americans (N = 4,188).ResultsAfter controlling for differences in gender and age, all Asian subgroups had significantly lower odds of having ever received screening in 2001 than the reference group of Japanese Americans. In addition, Korean Americans were the only subgroup that had a statistically significant decline in screening prevalence from 2001 to 2005 compared to the trend among Japanese Americans. After controlling for differences in education, marital status, employment status and federal poverty level, Korean Americans were the only group that had significantly lower screening prevalence than Japanese Americans in 2001, and their trend to 2005 remained significantly depressed. After controlling for differences in English proficiency and access to care, screening prevalences in 2001 were no longer significantly different among the Asian subgroups, but the trend among Korean Americans from 2001 to 2005 remained significantly depressed. Korean and Vietnamese Americans were less likely than other groups to report a recent doctor recommendation for screening and more likely to cite a lack of health problems as a reason for not obtaining screening.ConclusionsDifferences in CRC screening trends among Asian ethnic groups are not entirely explained by differences in demographic characteristics, English proficiency and access to care. A better understanding of mutable factors such as rates of doctor recommendation and health beliefs will be crucial for designing culturally appropriate interventions to promote CRC screening.

Results of a community-based randomized trial to increase colorectal cancer screening among Filipino Americans.

OBJECTIVES We conducted 1 of the first community-based trials to develop a multicomponent intervention that would increase colorectal cancer screening among an Asian American population. METHODS Filipino Americans (n = 548) nonadherent to colorectal cancer (CRC) screening guidelines were randomized into an intervention group that received an education session on CRC screening and free fecal occult blood test (FOBT) kits; a second intervention group that received an education session but no free FOBT kits; and a control group that received an education session on the health benefits of physical activity. RESULTS Self-reported CRC screening rates during the 6-month follow-up period were 30%, 25%, and 9% for participants assigned to intervention with FOBT kit, intervention without the kit, and control group, respectively. Participants in either of the 2 intervention groups were significantly more likely to report screening at follow-up than were participants in the control group. CONCLUSIONS A multicomponent intervention that includes an educational group session in a community setting can significantly increase CRC screening among Filipino Americans, even when no free FOBT kits are distributed.

Conducting health research in Korean American churches: perspectives from church leaders.

Korean Americans experience many challenges to obtaining adequate health care coverage and access to needed services. Because a large proportion of Korean Americans attend churches on a regular basis, churches may be a promising venue where health programs can be delivered. In order to gain an in-depth understanding of Korean American churches with respect to conducting future health intervention research, we conducted exploratory interviews and focus groups with 58 leaders from 23 Korean American churches and three community organizations. From these interviews and focus groups, we found that Korean churches and church leaders seek to meet a variety of social and health needs of their congregation and their surrounding community. Several leaders have stated that assisting with social and medical needs of their members is an important component of their current ministry. They described profound health needs of their congregations and have suggested various ways in which the university can partner with the local churches to help address these needs through research. Additionally, they described various resources churches can provide to researchers such as: their personal assistance, church volunteer base, church facility, and church network and contacts. Our findings suggest that Korean churches have a high potential to serve an important role in the health of Korean Americans. On the basis of the promising results of the present study, we are planning to conduct a cross sectional survey of Korean church leaders and members in Los Angeles County to substantiate our findings in a larger representative sample.
