This is a published protocol for a randomized controlled trial called NOSH, designed to test a culturally adapted DASH-based telenutrition intervention among urban AI/AN adults with hypertension. Participants aged 18 or older who self-identify as AI/AN and have elevated systolic blood pressure (≥130 mmHg) will be randomized to receive eight weekly tailored telenutrition sessions with a registered dietitian plus $30 weekly for DASH foods, or printed low-sodium diet education materials plus $30 weekly grocery orders. Home blood pressure will be assessed at baseline, 8 weeks, and 12 weeks post-baseline. A sub-sample will complete extended assessments at 6 and 9 months. The study is notable as one of the first dietary intervention trials specifically targeting HTN in urban AI/AN adults. Strengths include cultural tailoring to include traditional foods and use of home BP monitoring. Limitations noted by the authors include potential contamination in tight-knit communities and the restriction to urban settings. If effective, the authors state the intervention could be scalable and inexpensive to implement in urban AI/AN communities.
