Note. BMI = body mass index; BP = blood pressure; CHW = community health worker; CI = confidence interval; FQHC1 = federally qualified health center 1; FQHC2 = federally qualified health center 2; HbA1c = glycated hemoglobin; HDL = high-density lipoprotein; LDL = low-density lipoprotein; TChol = total cholesterol. Matched on age, gender, insurance status (commercial, Medicaid, Medicare, self-pay), race, diagnoses (diabetes, cardiovascular disease, cardiovascular disease risk), and BMI category (underweight, normal, overweight, obese, morbidly obese).
a
Difference is defined as CHW – no CHW.
