Background Alaska Native and American Indian people (AN/AIs) have a high incidence of colorectal cancer (CRC) and CRC-related mortality. Screening can prevent death from CRC, but screening rates are low in racially and ethnically diverse populations. The authors conducted a randomized controlled trial using text messaging to increase CRC screening among unscreened AN/AIs in a tribal health care system in Anchorage, Alaska. Methods The intervention entailed up to 3 text messages sent 1 month apart. The authors randomized 2386 AN/AIs aged 40 to 75 years who were eligible for CRC screening to the intervention or usual-care control conditions. Screening status was ascertained from electronic health records 3 months and 6 months after the last text message. Hazard ratios (HRs) were estimated to evaluate the effectiveness of the intervention, stratified by age and sex. Results The intervention increased CRC screening for AN/AIs aged 50 to 75 years (HR, 1.42; 95% confidence interval [95% CI], 0.97-2.09) and aged 40 to 49 years (HR, 1.24; 95% CI, 0.95-1.62). Within both age groups, the HRs were higher for women (HR, 1.69 [95% CI, 1.02-2.80] and HR, 1.37 [95% CI, 1.01-1.88]) compared with men (HR, 1.09 [95% CI, 0.59-1.99] and HR, 0.90 [95% CI, 0.54-1.53]). Interaction analysis yielded P values of .55 and .09, respectively, for age and sex. Conclusions A simple text messaging intervention was found to increase CRC screening rates in AN/AIs, a group with high CRC morbidity and mortality. Text messaging may be a cost-effective means of reducing CRC screening disparities in AN/AIs and other populations. Cancer 2017;123:1382-1389. © 2016 American Cancer Society.

American Indians and Alaska Natives (AI/ANs) suffer a disproportionate burden of diabetes and kidney failure. For those with chronic kidney disease, transplantation may be the most effective treatment option. However, low rates of organ donation and transplantation are reported for AI/ANs, who face significant barriers in accessing the transplant waiting list. They are also less likely than Whites to consent to become organ donors. We partnered with five tribal colleges and universities to conduct focus groups to assess knowledge, cultural beliefs, and behaviors related to organ donation and transplantation among AI/AN college students. Focus group data were used to develop a culturally targeted media campaign and outreach strategy aimed at increasing rates of consent to donate organs. Community knowledge typically drew from direct family experience with chronic illness. Study findings confirmed that attitudes about organ donation were influenced by cultural beliefs. Nevertheless, many participants supported organ donation even when it conflicted with cultural and spiritual beliefs about keeping the body intact for burial. Participants also expressed mistrust of the local health care system, suggesting that trust issues might interfere with health messaging on this topic. This is the first study to examine sociocultural beliefs about organ donation among AI/AN college students. Through focus group findings, study staff were better positioned to develop culturally relevant outreach materials. Rising rates of chronic illness among AI/ANs ensure that organ donation and transplantation will be a long-term feature of the health landscape in AI/AN communities. Targeted health messaging must be part of the strategy to reduce donor shortages.

Aims: This study examined the prevalence of alcohol ads, the spatial relationship between alcohol ads and schools, churches and playgrounds, and area-level determinants of alcohol ad density in Central Harlem, New York City. Methods: Alcohol advertising was quantified using street observation. Data on city demographics and infrastructure were obtained from the census and municipal databases. Results: Alcohol ads were densely distributed; almost half of ads fell within a 152 m buffer of schools, churches and playgrounds; and ad density was positively associated with retail liquor outlet density. Conclusions: Predominantly Black neighbourhoods continue to face high exposure to outdoor alcohol advertising, including around sites at which youth congregate.
