Sponsored by Mayo Clinic · Observational
The aims of this study are to determine the types and severity of previously undiagnosed sleep deficiencies in otherwise healthy Somali Americans, apply a research framework to define psychosocial, behavioral, environmental, and biological mechanisms mediating sleep deficiencies in Somali Americans, and examine the relationship between sleep deficiencies and increased blood pressure in Somali Americans.
6,114 studies on the registry are indexed under Hypertension; 912 are open to participants now.
This study's planned enrollment of 240 is below the median of 350 across 1,163 observational studies indexed under Hypertension.

The research team will partner with Somali operated community-based health clinics, faith-based establishments, community organizations, charter schools and other educational/community centers. In addition, the research team will partner with the Somali Health Advisory Committee (SHAC), a community advisory board based in Rochester and Minneapolis/St. Paul and the Somali Community Resettlement Agency (SCRS) and Somali American Social Services Association (SASSA), two community organizations aimed at integrating Somali immigrants to the United States.

Started Nov 2022 (actual). Primary completion is estimated for Oct 2028, 71 months after the start.
Of 345 non-industry observational studies under Hypertension, half reached primary completion within 44 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 111. This study's planned 71 months is above that.
Counting every sponsor, half of 426 studies reached it within 38 months; a quarter within 17 and three quarters within 96.
