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.
