A randomized controlled trial of two interventions to increase colorectal cancer screening among Hispanics on the Texas-Mexico border.

BACKGROUND: Colorectal cancer (CRC) is the second and third leading cause of cancer death for Hispanic men and women, respectively. CRC can be prevented if precursors are detected early and removed and can be successfully treated if discovered early. While one-on-one interventions for increasing CRC screening (CRCS) are recommended, few studies specifically assess the effectiveness of lay health worker (LHW) approaches using different educational materials. PURPOSE: To develop and evaluate the effectiveness of two LHW-delivered CRCS interventions known as Vale la Pena (VLP; "It's Worth It!") on increasing CRCS among Hispanics. DESIGN: The study design was a cluster randomized controlled trial with two treatment arms. SETTING/PARTICIPANTS: Six hundred and sixty five Hispanics 50 years and older were recruited from 24 colonias (neighborhoods) in the Lower Rio Grande Valley of the Texas-Mexico border. INTERVENTION: The interventions were a small media print intervention (SMPI) (including DVD and flipchart), and a tailored interactive multimedia intervention (TIMI) delivered on tablet computers. A no intervention group served as the comparison group. Data were collected between 2007 and 2009 and analyzed between 2009 and 2013. MAIN OUTCOME MEASURES: Measures assessed CRCS behavior, self-efficacy, knowledge, and other psychosocial constructs related to CRCS and targeted through VLP. RESULTS: Among participants reached for follow-up, 18.9 % in the SMPI group, 13.3 % in the TIMI group, and 11.9 % in the comparison group completed CRCS. Intent-to-treat analysis showed that 13.6 % in the SMPI group, 10.2 % in the TIMI group, and 10.8 % in the comparison group completed CRCS. These differences were not statistically significant. CONCLUSION: Results indicated that there are no significant differences in CRCS uptake between groups.

Colorectal cancer screening among Latinos in three communities on the Texas-Mexico border.

OBJECTIVE: To assess colorectal cancer screening (CRCS) prevalence and psychosocial correlates of CRCS among Latinos in South Texas. METHOD: Using multivariable analyses, we examined the association of perceived susceptibility, self-efficacy, pros and cons, subjective norms, knowledge and fatalism on CRCS among 544 Latinos (50 years and older). RESULTS: In this socioeconomically disadvantaged population, 40% had never heard of any CRCS test, only 34% reported ever completing any type of CRCS, and only 25% were adherent to CRCS guidelines. Insurance status, gender, perceived cons, CRCS self-efficacy, and CRCS norms were significantly associated with CRCS. CONCLUSION: CRCS interventions in this population should focus on improving access, increasing self-efficacy and perceived norms, and decreasing negative perceptions of CRCS.

AMIGAS: a multicity, multicomponent cervical cancer prevention trial among Mexican American women.

BACKGROUND: Considerable efforts have been undertaken in the United States to reduce cervical cancer incidence and mortality by increasing screening; however, disparities in screening rates continue to exist among certain racial and ethnic minority groups. The objective of the current study was to determine the effectiveness of a lay health worker-delivered intervention-AMIGAS (Ayudando a las Mujeres con Informacion, Guia, y Amor para su Salud [helping women with information, guidance, and love for their health])-to increase Papanicolaou (Pap) test screening among 3 populations of women of Mexican origin. METHODS: Six hundred thirteen women of Mexican origin in 3 treatment sites were randomized among 4 study arms: the full AMIGAS program with a video and a flip chart (n = 151), the AMIGAS program without the video (n = 154), the AMIGAS program without the flip chart (n = 155), and a usual care control group (n = 153). Six months after enrollment, women were surveyed and reported whether or not they had been screened. RESULTS: Women in any of the intervention arms were statistically significantly more likely to report being screened than those in the usual care group in both an intent-to-treat analysis and a per-protocol analysis. In the intent-to-treat analysis, 25% of women in the control group and 52% in the full AMIGAS program group reported having had Pap tests (P < .001); in the per-protocol analysis, the percentages were 29% and 62%, respectively (P < .001). CONCLUSIONS: AMIGAS was effective in increasing Pap test screening among women of Mexican descent when used in a 1-to-1 setting. Future research should compare the 1-on-1 intervention with the group-based intervention.

A lifetime of violence: results from an exploratory survey of Mexican women with HIV.

Despite recognition that traditional Mexican gender norms can contribute to the twin epidemics of violence against women and HIV, there is an absence of published literature on experiences of violence among Mexican women with HIV. We conducted a cross-sectional survey with 77 HIV-infected women from 21 of Mexico's 32 states to describe experiences of violence before and after HIV-diagnosis. We measured lifetime physical, sexual, and psychological violence; physical violence from a male partner in the previous 12 months; and physical and psychological violence related to disclosing an HIV diagnosis. Respondents reported ever experiencing physical violence (37.3%) and sexual violence (29.2%). Disclosure of HIV status resulted in physical violence for 7.2% and psychological violence for 26.5% of the respondents. This study underlines the need to identify and address past and current gender-based violence during pre- and post-HIV test counseling and as a systematic and integral part of HIV care.

Breast and cervical cancer screening practices among Hispanic and non-Hispanic women residing near the United States-Mexico border, 1999-2000.

This study examined the breast and cervical cancer screening practices of Hispanic and non-Hispanic women (n = 3,568) in counties that approximate the US southern border region. According to the Health Resources Services Administration (HRSA), border counties are those in which any part of the county is within 100 kilometers (62.14 miles) of the border. The study used data from Behavioral Risk Factor Surveillance System (BRFSS) surveys of adults aged > or = 18 years conducted in 1999 and 2000. The study looked at recent use of mammography and the Papanicolaou (Pap) test. Hispanic women were less likely to have had a recent mammogram or Pap test as compared with non-Hispanic women in border counties, and as compared with Hispanic and non-Hispanic women in nonborder counties of Texas, New Mexico, Arizona, and California combined, and with other women in the United States. Results underscore the need for continued efforts to ensure that medically underserved women who live in the border region have access to cancer screening services.
