AIM-HI = Americans In Motion—Healthy Interventions; BMI = body mass index; BP = blood pressure; EQ-5D = A visual analog health state score.
Note: Models adjusted for repeated measures, clustering of patients within practices, age, comorbidities, education, sex, income, marital status, race, and ethnicity.
↵a Traditional practices, n = 197 patients; enhanced practices, n = 201 patients.
↵b Traditional practices, n = 171 patients; enhanced practices, n = 206 patients.
↵c Scored on a range from 1 to 7, based on heart rate, age, and sex, with higher scores indicating greater physical fitness.
↵d PrimeScreen is a brief dietary screening tool.
