Results The awareness were different among different economic level regions(according to the order of developed areas/more developed areas/less developed areas, the superior proportion were 10.71%, 7.24%, 7.17%, the poor proportion were 22.03%, 24.79%, 12.95%)(χ²=33.964, P < 0.001), the rate of awareness in economically developed areas and economically underdeveloped areas showed a trend of polarization. The awareness of different diseases was different(according to the order of pathogenic characteristics, clinical manifestations, epidemiological features, the order of personal precautions, the superior proportion were 5.32%, 11.27%, 16.35%, 4.14%, the poor proportion were 32.14%, 24.59%, 19.70%, 28.77%)(χ²=48.823, P < 0.001). The social factors that affect the rate of awareness were disease prevention information acquisition channels(95%CI:0.141-0.706) and ethnic groups (95%CI:2.418-7.222), the clinical factors affecting the awareness were frequency of diarrhea(95%CI:0.113-0.860), history of food poisoning(95%CI:0.121-0.687) and history of parasitic diseases(95%CI:0.134-0.849).
