Scores indicate change from reference group: gender = male, race = white, household income = ≥ $90,000, age = 35–44, BMI = normal weight, group = low risk, geographic region = Pacific, household size = 1.
p < 0.05 vs. reference group for all values. Dropped = level of variable dropped from model during stepwise regression, no beta coefficient computed. SHIELD, Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes; BMI, body mass index.
