McGarvey examines the role of genetic variation in influencing the extent of obesity in Samoa. In-depth dietary, physical activity, socio-demographic and village environmental information is collected from more than 3,000 adult Samoans residing throughout the developing country of Samoa. Genome scan methods will be used to identify across the whole genome susceptibility loci for obesity in this population.
McGarvey leds an interdisciplinary behavioral intervention clinical trial to improve type 2 diabetes patient outcomes by expanding community health worker outreach. The community health workers will expand the dietary and physical activity education of patients and their families; provide reminders and active follow-up for clinic appointments.
