Factors Associated with Cancer Screening Among Hopi Men.

Cancer screening rates remain low among American Indian men, and cancer screening behaviors and barriers to cancer screening among American Indian men are not well understood. This study evaluated cancer screening behaviors in 102 Hopi men who were 50 years of age or older from the Hopi Survey of Cancer and Chronic Disease. Reported cancer screening frequencies were 15.7%, 45.1%, and 35.3% for fecal occult blood test (FOBT), colonoscopy, and prostate-specific antigen (PSA) test, respectively. Among men who reported having had a FOBT, 81.2% had the test more than 1 year ago. Among men who reported a colonoscopy, 60.8% had colonoscopy within the past 3 years. Similarly, among men who reported having had PSA, 72.3% had PSA within the past 3 years. "No one told me" was the most common answer for not undergoing FOBT (33.7%), colonoscopy (48.2%), and PSA (39.4%). Men who reported having had a PSA or digital rectal exam were three times as likely to also report having a FOBT or colonoscopy (odds ratio [OR] 3.19, 95% confidence interval [CI]: 1.21-8.46). Younger age (< 65) was associated with reduced odds of ever having prostate cancer screening (OR 0.28, 95% CI: 0.10-0.77). Ever having colorectal cancer screening and previous diagnosis of cancer increased odds of ever having prostate cancer screening (OR 3.15, 95% CI: 1.13-8.81 and OR 5.28, 95% CI: 1.15-24.18 respectively). This study illustrates the importance of community cancer education for men to improve cancer screening participation.

Caregiving on the Hopi Reservation: Findings from the 2012 Hopi Survey of Cancer and Chronic Disease.

A family caregiver provides unpaid assistance to a family member/friend with a chronic disease, illness or disability. The caregiving process can affect a caregiver's quality of life by reducing time for themselves, for other family members and for work. The 2000 Behavioral Risk Factor Surveillance Survey estimates that 16 % of adult American Indians (AIs) are caregivers. A 2012 survey collected knowledge and personal experience data from a random sample of Hopi men and women (248 men and 252 women). Self-identified caregivers answered questions on time spent caregiving, caregiver difficulties and services requested. Approximately 20 % of the 500 Hopi participants self-identified as caregivers (N = 98), with 56 % female. Caregivers in contrast to non-caregivers had a lower percentage of ever having a mammogram (86, 89 %), a higher percentage of ever having had a Pap smear test (89.1, 85.6 %), a prostate specific antigen test (35, 30.6 %) and ever having had a colonoscopy (51.2, 44 %). Almost 21 % of caregivers reported difficulty with stress and 49 % reported it as their greatest caregiver difficulty. More males (28.6 %) identified financial burden as the greatest difficulty than females (p = 0.01). Training on patient care was the service that caregivers would like to receive most (18.2 %). The percentage of Hopi's providing caregiving was similar to national averages, although among men, was somewhat higher than national data (44 vs. 34 %). Stress was identified as a difficulty, similar to national studies.

Cancer Screening on the Hopi Reservation: A Model for Success in a Native American Community.

American Indian women have lower cancer survival rates compared to non-Hispanic White women. Increased cancer screening fostered by culturally sensitive education and community programs may help decrease this disparity. This study assesses the effectiveness of Hopi Cancer Support Services (HCSS) in maintaining high rates of breast and cervical cancer screening among Hopi women and evaluates the impact of participation in HCSS programs on colorectal cancer (CRC) screening. A population-based survey was conducted on the Hopi reservation in 2012 (n = 252 women). Frequency of breast, cervical, and colorectal cancer screenings, participation in HCSS programs and barriers to screening were evaluated. Unconditional multiple logistic regression estimated the independent effect of the HCSS program on CRC screening. Approximately 88 % of Hopi women 40+ reported ever having had a mammogram; 71 % did so within the past 2 years. Approximately 66 % of women 50+ were ever screened for colorectal cancer (FOBT and/or colonoscopy). Women who had their last mammogram through HCSS were 2.81 (95 % CI 1.12, 7.07) times more likely to have been screened for CRC. Breast and cervical cancer screening continues at a high rate among Hopi women and is substantially greater than that reported prior to the inception of HCSS. Furthermore, participation in programs offered by HCSS is strongly associated with increased colorectal cancer screening. This tribal health program (HCSS) has strongly influenced cancer screening among Hopi women and is a model of a tribally run cancer prevention program.

Drinking water and health assessment in a Northern Arizona community.

Arizona is a mineral rich state that relies on a mix of surface and ground water supplies for drinking water requirements. Small, rural water systems relying on groundwater frequently encounter elevated metal(loid) measures, particularly inorganic arsenic (As +3, +5). Such contaminant occurrences can be associated with adverse health outcomes including cancers. The Hopi Environmental Health Project examined drinking water quality and water consumption behaviors from 76 homes on Hopi lands over a four-year period. Water samples were analyzed for 28 elements and compared to US Environmental Protection Agengy (EPA) maximum contaminant levels (MCL). Only municipal/piped water had a mean arsenic concentration (11.01 µg/L) exceeding the MCL (10.0 µg/L). All other water types and elements occurred below MCL when detected. A lifetime cancer and hazard quotient associated with arsenic consumption through each water type was performed and piped/municipal water was found to carry the greatest risks (9.96 cases per 10,000 people). Results from this study showed the potential for multiple contaminants to be present in drinking water from Hopi lands and the need for further health assessment of routine exposure to low doses of contaminant mixtures through drinking water.

Formative Assessment to Improve Cancer Screenings in American Indian Men: Native Patient Navigator and mHealth Texting.

Cancer screening rates among American Indian men remain low, without programs specifically designed for men. This paper describes the Community-Based Participatory Research processes and assessment of cancer screening behavior and the appropriateness of the mHealth approach for Hopi men's promotion of cancer screenings. This Community-Based Participatory Research included a partnership with H.O.P.I. (Hopi Office of Prevention and Intervention) Cancer Support Services and the Hopi Community Advisory Committee. Cellular phone usage was assessed among male participants in a wellness program utilizing text messaging. Community surveys were conducted with Hopi men (50 years of age or older). The survey revealed colorectal cancer screening rate increased from 51% in 2012 to 71% in 2018, while prostate cancer screening rate had not changed (35% in 2012 and 37% in 2018). Past cancer screening was associated with having additional cancer screening. A cellular phone was commonly used by Hopi men, but not for healthcare or wellness. Cellular phone ownership increased odds of prostate cancer screening in the unadjusted model (OR 9.00, 95% CI: 1.11-73.07), but not in the adjusted model. Cellular phones may be applied for health promotion among Hopi men, but use of cellular phones to improve cancer screening participation needs further investigation.

Process for determining the cancer burden of the Hopi Tribe.

The Hopi Tribe is located in the northeastern part of Arizona on more than one million acres of federally reserved land. Tribally based community research, conducted in collaboration with University of Arizona researchers, has been successfully implemented on Hopi beginning with a cross-sectional community survey in 1993 and continuing with a second survey in 2006. Both surveys identified a strong community interest in cancer. This article reports on the process involved in a third study, in which official Hopi enrollment data were matched with Arizona Cancer Registry data. The process involved bringing in a new partner and obtaining tribal, state, and university approvals, as well as a signed data exchange agreement between the state and the Hopi Tribe. Technical implementation of the data match required computer programming and epidemiologic expertise, as well as an understanding of the community and the culture. Close collaboration among Hopi residents and university epidemiologists was critical.

A Southwestern Tribal Perspective on Traditional and Commercial Tobacco.

American Indian or Alaska Natives have the highest rates of current cigarette (36.5%) and smokeless tobacco use (5.3%), and tobacco product (40.1%) and the second highest rate of current cigar use (6.1%) compared to all other racial-ethnic groups in the U.S. rates of American Indian or Alaska Native tobacco use vary by gender. Few studies examine perceptions of tobacco use among tribal members residing on and off the reservation. This study fills a gap in the literature by reporting the perceptions of 34 enrolled members of a southwestern tribe who reside on and off a tribal land using a Community-Based Participatory Research (CBPR) design through a collaboration between a university and a tribal health program. Researchers conducted seven focus groups; four on the southwest reservation and three within an urban community. The discussions were audio-recorded, transcribed, and analyzed using a multi-investigator consensus model. The use of tobacco (commercial or traditional) in southwest tribes is essential to cultural practices. Results depicted different views on cultural meaning and health impacts of commercial and traditional tobacco. Findings suggest the importance of local research to understand dimensions of tobacco use before moving forward with tobacco cessation programming.
