目的评价镇江市润州区人群土源性线虫病防治效果。方法在实施药物驱虫、健康教育、改水改厕为主综合防治措施的同时,开展居民土源性线虫感染监测,调查当地经济指标、自来水和无害化厕所普及率,进行防治效果评价。结果 1997-2012年全区实施集体化疗累计20.21万人次,粪检阳性驱虫化疗2 006人次。居民健康知识知晓率1997年为57.18%,2012年达95.62%;自来水和无害化厕所普及率1997年分别为10.14%和10.21%,2012年分别为100.0%和90.38%。居民土源性线虫感染率与人均国内生产总值和居民人均年纯收入均呈显著负相关(r人均国内生产总值=-0.526,P<0.05;r居民人均年纯收入=-0.671,P<0.01);与自来水普及率、无害化厕所普及率和健康知识知晓率间也均呈显著负相关(r自来水普及率=-0.936,r无害化厕所普及率=-0.922,r健康知识知晓率=-0.774,P均<0.01)居民土源性线虫感染率呈指数曲线下降趋势(y=42.031 7e-0.357 6x,R2=0.803 6,F=57.28,P=0.000)。务农人员感染率显著高于学生(χ2=17.998,P<0.01),男、女感染率差异无统计学意义(χ2=3.627,P=0.057)。结论综合性防治措施实施及社会经济发展有助于人群土源性线虫感染率的持续下降。
Objective To evaluate the prevention and control of soil-borne nematodes in the population of Runzhou District, Zhenjiang City. Methods At the same time of carrying out comprehensive prevention and control measures such as drug deworming, health education and water improvement and toilet rescuing, the residents were monitored for soil-borne nematode infection, investigated the local economic indicators, tap water and harmless toilets, and evaluated the effect of prevention and treatment. Results From 1997 to 2012, the cumulative total number of community-based chemotherapy was 202,100 and that of fecal seizures was 2,006. The awareness rate of residents’ health knowledge was 57.18% in 1997 and 95.62% in 2012, while that of tap water and harmless toilets was 10.14% and 10.21% respectively in 1997 and 100.0% and 90.38% respectively in 2012. The infection rate of soil-borne nematodes was negatively correlated with the per capita annual net income of the residents (r per capita = -0.526, P <0.05; r per capita annual net income = -0.671, P <0.01). There was also a significant negative correlation between tap water penetration rate, innocent toilets penetration rate and health knowledge awareness rate (r tap water penetration rate = -0.936, r harmless toilet penetration rate = -0.922, r health knowledge The infection rate of residents with soil-borne nematodes decreased exponentially (y = 42.031 7e-0.357 6x, R2 = 0.803 6, F = 57.28, P = 0.000). The infection rate of farm workers was significantly higher than that of students (χ2 = 17.998, P <0.01). There was no significant difference in infection rates between male and female (χ2 = 3.627, P = 0.057). Conclusion The implementation of comprehensive prevention and control measures and socio-economic development contribute to the continuous decline of population infection rate of soil-borne nematodes.
