Colorectal Cancer Screening Uptake's Association With Psychosocial and Sociodemographic Factors Among Homeless Blacks and Whites.

The homeless represent an extremely disadvantaged population that fare worse than minority groups in access to preventive services and health, and minority groups fare worse than Whites. Early detection screening for colorectal cancer (CRC) saves lives, but empirical data about CRC screening practices among homeless Blacks and Whites are limited. Psychosocial risk factors may serve as a barrier to CRC screening completion among homeless Black individuals. A secondary data analysis of a randomized clinical trial for smoking cessation among homeless smokers was conducted to determine whether psychosocial factors and sociodemographic factors were more highly associated with CRC screening uptake among homeless Blacks than among their White counterparts. Study participants ( N = 124) were surveyed on their CRC screening status, sociodemographic variables, and psychosocial correlate measures including anxiety, depression, hopelessness, depression severity, and perceived stress. Associations between these factors were examined with logistic regression. White participants who were currently disabled/unable to work were 6.2 times more likely to ever receive CRC screening than those who were employed. Black participants with public health insurance coverage were 90% less likely to ever obtain CRC screening than participants without health insurance. Black and White participants had similar levels of anxiety symptoms, depression, and hopelessness, yet depression was the only psychosocial variable negatively associated with CRC screening status. Black and White participants with symptoms of depression were 58% less likely to complete screening than those without depression. Mental health risk and sociodemographic factors may serve as barriers to CRC screening among homeless Blacks and Whites.

Prevalence of cardiovascular risk factors across six African Immigrant Groups in Minnesota.

BACKGROUND: Although African immigrants represent a large and growing segment of the U.S. population, there are little or no data available on the prevalence of cardiovascular disease (CVD) risk factors among this diverse population. This study compared the prevalence of self-reported CVD risk factors and health behaviors and examined the associations between immigration related characteristics and CVD risk factors and health behaviors across six African immigrants groups. METHODS: Data were from 996 African immigrants in the U.S., (37.9% Somalis; 26.8% Ethiopians; 14% Liberians; 8.5% Sudanese; 5.1% Kenyans and 7.8% others group) from a cross-sectional survey conducted in the Twin cities of Minnesota. Logistic regression models estimated the associations of demographic characteristics, and immigration-related factors (length of stay in the United states, English proficiency, income and health insurance) with prevalence of CVD risk factors (overweight/obese; hypertension and diabetes mellitus) and self-reported health behaviors (cigarette smoking, physical inactivity, conscious effort to exercise and eating a healthy diet). RESULTS: We found a relatively low self-reported prevalence of diabetes, hypertension, and smoking. However, significant differences were noted by country of origin. Using Somalis as our referent country of origin group, we found that Liberians and Kenyans were more likely to report having diabetes or hypertension. On all measures of health behaviors, Liberians were more likely to engage in more health protective behaviors than other individuals. CONCLUSIONS: Although African immigrants have different prevalence rates for CVD risk factors and health behaviors, there is a need to further explore the differences observed by country of emigration.

Cervical cancer screening with clinic-based Pap test versus home HPV test among Somali immigrant women in Minnesota: a pilot randomized controlled trial.

UNLABELLED: Cervical cancer is more common in the Somali immigrant population than the general population in the United States (US). There are low rates of cervical cancer screening among Somali women. This study compares cervical cancer screening test completion rates for a home human papilloma virus (HPV) test and standard clinic Pap test. Sixty-three Somali immigrant women aged 30-70 years who had not undergone cervical cancer screening within the past 3 years were randomly assigned to a home HPV test group (intervention) or a clinic Pap test group (control). Test completion rates were measured at 3 months. Univariate and multivariate logistic regression models were used to explore factors associated with test completion (intention-to-treat analysis). Participants in the HPV test group were 14 times more likely to complete the test compared to those in the Pap test group (P = 0.0002). Women who reported having friends/family members to talk about cancer screening were approximately three times more likely to complete any screening test than those who did not (P = 0.127) and participants who reported residing in the US longer were more likely to complete a screening test (P = 0.011). Future research should explore the potential of using the home-based HPV test kits as an initial approach to cervical cancer screening. IMPACT: The use of a self-sampling HPV kit has the potential to increase cervical cancer screening in under-served communities in the US.

Cervical cancer: barriers to screening in the Somali community in Minnesota.

This study examined barriers to and facilitators of cervical cancer screening among Somali immigrant women in Minnesota. We adopted the socioecological framework to illustrate screening barriers at multiple levels. We conducted 23 semi-structured key informant interviews and used a thematic exploratory approach to analyze the data. Barriers were classified into individual, community or health systems levels. Obstacles included lack of knowledge, religious beliefs, fatalism, fear, embarrassment, and lack of trust in the interpreters. Participants described a need for training of healthcare providers on issues surrounding Somali women's cultural practices and sexual health. Identifying individual, community, or health system barriers and addressing them concurrently may increase use of cancer screening services among Somali women. Future interventions need to address multilevel barriers with multilevel approaches to improve utilization of cervical cancer screening services in underserved immigrant populations in the United States.

Understanding cancer screening service utilization by Somali men in Minnesota.

This study examined factors that influence use of cancer screening by Somali men residing in Minnesota, USA. To better understand why recent immigrants are disproportionately less likely to use screening services, we used the health belief model to explore knowledge, beliefs, and attitudes surrounding cancer screening. We conducted a qualitative study comprised of 20 key informant interviews with Somali community leaders and 8 focus groups with Somali men (n = 44). Somali men commonly believe they are protected from cancer by religious beliefs. This belief, along with a lack of knowledge about screening, increased the likelihood to refrain from screening. Identifying the association between religion and health behaviors may lead to more targeted interventions to address existing disparities in cancer screening in the growing US immigrant population.

Smoking cessation in homeless populations: who participates and who does not.

INTRODUCTION: Although homeless individuals smoke at an alarmingly high rate, few smoking cessation clinical trials have focused on this vulnerable population. Little is known about recruitment efforts and suitable eligibility criteria for tobacco control research in homeless populations. METHODS: The aim of this article is to describe the recruitment, eligibility, and enrollment of homeless smokers who participated in the Power to Quit smoking study, a randomized smoking cessation clinical trial funded by the National Institutes of Health. The study compared motivational interviewing and standard counseling while participants received an 8-week treatment of the nicotine patch. RESULTS: Working with local emergency shelters, a total of 839 adult smokers were screened for study eligibility, 580 of whom (69.1%) met eligibility criteria. Of those eligible, 430 (74.1%) returned for randomization. Those who returned for randomization were older and more likely to have a phone number compared with eligible participants not enrolled. The most common reasons for exclusion included exhaled carbon monoxide levels less than or equal to 5 parts per million (indicating nonsmoking status), use of smoking cessation aid during the past 30 days, and not meeting the study definition of homelessness. CONCLUSION: Knowledge of these factors may help researchers tailor criteria that accurately identify and include homeless smokers in future research.

Motivational interviewing to enhance nicotine patch treatment for smoking cessation among homeless smokers: a randomized controlled trial.

AIMS: To assess the effects of adding motivational interviewing (MI) counseling to nicotine patch for smoking cessation among homeless smokers. DESIGN: Two-group randomized controlled trial with 26-week follow-up. PARTICIPANTS AND SETTING: A total of 430 homeless smokers from emergency shelters and transitional housing units in Minneapolis/St Paul, Minnesota, USA. INTERVENTION AND MEASUREMENTS: All participants received 8-week treatment of 21-mg nicotine patch. In addition, participants in the intervention group received six individual sessions of MI counseling which aimed to increase adherence to nicotine patches and to motivate cessation. Participants in the standard care control group received one session of brief advice to quit smoking. Primary outcome was 7-day abstinence from cigarette smoking at 26 weeks, as validated by exhaled carbon monoxide and salivary cotinine. FINDINGS: Using intention-to-treat analysis, verified 7-day abstinence rate at week 26 for the intervention group was non-significantly higher than for the control group (9.3% versus 5.6%, P = 0.15). Among participants who did not quit smoking, reduction in number of cigarettes from baseline to week 26 was equally high in both study groups (-13.7 ± 11.9 for MI versus -13.5 ± 16.2 for standard care). CONCLUSIONS: Adding motivational interviewing counseling to nicotine patch did not increase smoking rate significantly at 26-week follow-up for homeless smokers.

Shortening treatment in adults with noncavitary tuberculosis and 2-month culture conversion.

RATIONALE: Cavitary disease and delayed culture conversion have been associated with relapse. Combining patient characteristics and measures of bacteriologic response might allow treatment shortening with current drugs in some patients. OBJECTIVES: To assess whether treatment could be shortened from 6 to 4 months in patients with noncavitary tuberculosis whose sputum cultures converted to negative after 2 months. METHODS: This study was a randomized, open-label equivalence trial. HIV-uninfected adults with noncavitary tuberculosis were treated daily with isoniazid, rifampin, pyrazinamide, and ethambutol for 2 months, followed by 2 months of isoniazid and rifampin. After 4 months, patients with drug-susceptible TB whose sputum cultures on solid media were negative after 8 weeks of treatment were randomly assigned to continue treatment for 2 more months or to stop treatment. Patients were followed for relapse for 30 months after beginning treatment. MEASUREMENTS AND MAIN RESULTS: Enrollment was stopped by the safety monitoring committee after 394 patients were enrolled due to apparent increased risk for relapse in the 4-month arm. A total of 370 patients were eligible for per protocol analysis. Thirteen patients in the 4-month arm relapsed, compared with three subjects in the 6-month arm (7.0 vs. 1.6%; risk difference, 0.054; 95% confidence interval with Hauck-Anderson correction, 0.01-0.10). CONCLUSION: Shortening treatment from 6 to 4 months in adults with noncavitary disease and culture conversion after 2 months using current drugs resulted in a greater relapse rate. The combination of noncavitary disease and 2-month culture conversion was insufficient to identify patients with decreased risk for relapse.
