Note. BMI = body mass index; CHW = community health worker; CVD = cardiovascular disease; FQHC1 = federally qualified health center 1; FQHC2 = federally qualified health center 2; SMD = standard mean difference. Mean ±SD is given for continuous variables and percentages are given for categorical variables. No CHW group is matched to CHW group on age, gender, insurance status (commercial, Medicaid, Medicare, self-pay), race/ethnicity (Hispanic White, non-Hispanic White, other), diagnoses (diabetes, CVD, CVD risk), and BMI category (underweight, normal, overweight, obese, morbidly obese).
All group-wise P > .25.
All group-wise P > .1 except insurance type (P < .001).
