title: [Effect of comprehensive prevention and control of soil-transmitted nematodiasis in Runzhou District of Zhenjiang City].
abstract: OBJECTIVE
  To evaluate the effect of comprehensive prevention and control of soil-transmitted nematodiasis in Runzhou District, Zhenjiang City, Jiangsu Province from 1997 to 2012.
  
  
  METHODS
  The comprehensive prevention and control measures included the helminthicide, health education, improvement of water supplier and harmless toilets, and these measures were implemented continuously. At the same time, the infection rates of soil-transmitted nematodes, the local economic indicators, and the coverage rates of tap water and harmless toilets were surveyed.
  
  
  RESULTS
  The mass chemotherapy was performed for 202 100 person-times and the diagnosed chemotherapy was performed for 2 006 person-times in Runzhou District from 1997 to 2012. The awareness rates of health knowledge were 57.18% in 1997, and 95.62% in 2012. The coverage rates of tap water and harmless toilets were 10.14% and 10.21% in 1997, and 100.0% and 90.38% in 2012, respectively. There were negative correlations between the awareness rate of per capita GDP, per capita net income, coverage rates of tap water, coverage rates of harmless toilets, health knowledge and the infection rate of soil-transmitted nematodes, respectively (r(per capitaGDP) = -0.526, P < 0.05; r(per capita net income) = -0.671, P < 0.01; r(coverage rates of tap water) = -0.936, P < 0.01; r(coverage rates of harmless toilets) = -0.922, P < 0.01; r(awareness) = -0.774, P < 0.01). The statistical analysis showed that the infection rate of soil-transmitted nematodes had a downward trend as an exponential curve in Runzhou District from 1997 to 2012 (y = 42.031 7e(-0.357 6x), R2 = 0.803 6, F = 57.28, P = 0.000). The infection rate of degradation by an annual rate was 29.18%. The infection rate in farmers was significantly higher than that in students (χ2 = 17.998, P < 0.01). There was no significant difference between men and women in the infection rate of soil-transmitted nematodes (χ2 = 3.627, P = 0.057).
  
  
  CONCLUSIONS
  The comprehensive prevention and control measures and the development of social economy contribute to the steady decline of soil-transmitted nematode infections.
