Project location: Rural communities in western Alaska
Category: Obesity, Type 2 Diabetes and Cardiovascular Disease
Project Description: The purpose of the Western Alaska Tribal Collaborative for Health (WATCH) Study is to combine four large adult cohort studies to obtain reliable data on prevalence and incidence of cardiovascular disease (CVD), stroke, and type 2 diabetes (DM2) in more than 4,500 Western Alaska Native people residing in the Norton Sound and Yukon-Kuskokwim regions of Alaska. The four cohorts include: (1) The Center for Alaska Native Health Research (CANHR) study, a longitudinal community-based participatory study recruited from 2003 until 2010; (2) The Alaska Education and Research Toward Health (EARTH) study, a multi-center community-based observational study recruited between 2004 and 2006; (3) The Genetics of Coronary Artery Disease in Alaska Natives (GOCADAN) study, conducted between 2000 and 2004; and (4) The Alaska-Siberia Project (ASP), conducted in 1994 and 1998.
A consolidated dataset from the four cohorts was created, allowing sufficient power to analyze population-based data on CVD and DM2 in this population. Determining the population-based incidence of these chronic diseases over time will allow researchers to examine factors that increase disease risk in those living in these regions. More importantly, it will also enable researchers to identify population-specific protective factors that can help prevent these chronic diseases.
