目的 探讨舒城地区菜农钩虫感染的影响因素。方法 采用菜农钩虫感染状况居民问卷调查表,调查菜农一般人口学资料、日常生活行为和居民粪便钩虫感染情况;使用改良加藤厚涂片法检查粪便钩虫卵,采用单因素和多因素logistic回归方法分析钩虫感染的影响因素。结果 共调查565名菜农,其中粪检钩虫阳性33例,钩虫感染率为5.84%。单因素分析发现,年龄、文化程度、种植方式、施肥类型、厕所类型、饮用水类型、清洗蔬菜或瓜果水源、饭前和便后洗手、赤脚下地劳作11个因素(P<0.05)是钩虫感染的影响因素。多因素logistic回归分析发现饭前洗手(OR值 0.241,95% CI:0.113,0.514)和使用发酵肥(OR值 0.121,95% CI:0.041,0.355)可以降低钩虫感染的风险,而年龄≥60岁(OR值 3.699,95% CI:1.459,9.378)是增加感染风险因素。结论 舒城县山区菜农钩虫感染率较高,倡导良好卫生习惯和使用发酵肥能够降低舒城山区老年菜农钩虫感染风险。

Objective To explore the influencing factors of hookworm infection in vegetable farmers in Shucheng area. Methods A questionnaire survey was used to collect the general demographic data,daily life behavior factors and infection status of hookworms in residents.The modified Kato’s thick smear method was used to examine the hookworm eggs,in feces.Univariate and multivariate logistics regression methods were used to analyze the influencing factors of hookworm infection. Results A total of 565 vegetable farmers were surveyed during the study period,of which 33 were positive for fecal tests,and the rate of hookworm infection was 5.84%.Univariate analysis found that 11 factors including age,education level,planting method,fertilization type,toilet type,drinking water type,water source for washing vegetables or fruits,washing hands before and after meals,and barefoot field work (P<0.05) were the influencing factors of hookworm infection..Multivariate logistic regression analysis further found that washing hands before meals (OR value 0.241,95% CI:0.113,0.514) and the use of fermented fertilizers (OR value 0.121,95% CI:0.041,0.355) can reduce the risk of hookworm infections,while people over 60 years old (OR value 3.699,95% CI:1.459,9.378) were at increased risk of infection. Conclusion The infection rate of hookworms in vegetable farmers of Shucheng County is relatively high.Good hygiene habits and the use of fermented fertilizer can reduce the risk of hookworm infection among elderly vegetable farmers in the mountainous area of Shucheng County.
