“…Among the hypertensive patients with different medical insurance types, the knowledge level of hypertensive patients with urban workers' medical insurance was the highest, Referring to "without medical insurance" as dumb variable: I1 = Medical insurance for urban workers (1, 0, 0, 0), I2 = Medical insurance for urban residents (0, 1, 0, 0), I3 = New rural cooperative medical insurance (0, 0, 1, 0), I4 = others (0, 0, 0, 1) History of hypertension < 3 years = 1; 3-4 years = 2; 5-9 years = 3; ≥ 10 years = 4 Family history of hypertension Yes = 1; no = 2 Hypertension complication Yes = 1; no = 2 Kinds of antihypertensive medication being taken 1 or below = 1; 2-3 kinds = 2; 4 or above = 3 followed by the new rural cooperative medical insurance and urban residents' medical insurance, and the knowledge level of hypertensive patients without medical insurance was the lowest. The results of multiple linear regression analysis also show that the type of medical insurance is one of the factors affecting the knowledge level of hypertension patients, which may be because patients with urban residents' medical insurance have better economic conditions [34][35][36]. Furthermore, due to better medical reimbursement in such two kinds of medical insurance, patients may take less concern of medical expenses and focus mainly on their disease.…”
