RESUMEN
INTRODUCTION: Innovations are needed for preventing cardiovascular disease (CVD) and for reaching diverse communities in remote regions. The current study reports on a telemedicine-delivered intervention promoting a traditional heart-healthy diet and medication adherence with Alaska Native men and women residing in the Norton Sound region of Alaska. METHODS: Participants were 299 men and women with high blood pressure or high cholesterol smoking daily who were randomized to receive telemedicine-delivered counseling and printed materials on diet and medication adherence or on smoking and physical activity. Intervention contacts were at baseline and 3-, 6-, and 12-months follow-up, with a final assessment at 18 months. Nutrition outcomes were the ratio of heart-healthy foods and traditional heart-healthy foods relative to all foods reported on a 34-item food frequency questionnaire. Recent and typical adherence for heart medications were self-reported. RESULTS: Intervention effects were significant for the heart-healthy foods ratio at 6 months only (p = 0.014) and significant for the traditional heart-healthy foods ratio at 6 months only for those aged 47+ (p = 0.031). For recent and typical medication adherence, there were no significant group differences by time. DISCUSSION: In a remote region of Alaska, telemedicine proved feasible and acceptable for engaging Alaska Native men and women in counseling on CVD risk behaviors. The findings indicate that more touchpoints may be necessary to impart comprehensive lasting change in heart-healthy eating patterns. Medication adherence group differences were not significant; however, medication adherence was high overall.

Though not native to Alaska, tobacco use is common among Alaska Native people in the Norton Sound region, an area consisting of 16 communities with population size 107 to 3,695. We summarise best practices in recruiting Alaska Native adults who smoke for a randomised controlled tobacco treatment trial. Participants were Alaska Native, 19 years and older, smoking daily, with hypertension and/or high cholesterol, residing in the Norton Sound region of Alaska. Study staff travelled to the remote communities to recruit, typically staying 5 days. Screening and enrolment success was examined by day, season, and staffing level. From June 2015 - December 2018, the study team made 122 trips, screening 1089 individuals and enrolling 314 participants. In the field, days 2-3 (51%) were best for screening, while days 3-4 (53%) had the greatest enrolment. Community size correlated with enrolment (r = 0.83, p <.001). Recruitment was optimised in spring and with multiple staff in the field. Despite challenges (e.g., harsh weather, poor internet connectivity), with active outreach (e.g. tabling in busy areas, attending community events, utilising mixed media, collaborating with clinic staff), the project reached its recruitment goal. Study findings can inform community-based tobacco treatment research trials in remote areas.
