Objective To evaluate the genitourinary system health of vegetable greenhouse growers and analyze related influencing factors.
Methods From April to May 2015, 460 vegetable greenhouse growers were selected by cluster random sampling method from three districts and two counties of Yinchuan and interviewed by questionnaires. Influencing factors for genitourinary system health were identified using logistic regression models.
Results A total of 448 vegetable greenhouse growers (207 females and 241 males) were enrolled in the study, with a valid questionnaire return rate of 97.4%. The self-reported genitourinary disease prevalence rate reached 75.8% in the female growers. The results of multiple logistic regression analysis showed that increased frequency of spraying pesticides (OR=3.683, 95%CI: 1.261-10.760) and chatting during pesticides spraying (OR=2.532, 95%CI: 1.056-6.068) were risk factors for female growers' genitourinary diseases, while using abamectin (OR=0.311, 95%CI: 0.132-0.730) was a protective factor. The self-reported genitourinary disease prevalence rate was 14.1% in the male growers. The results of multiple logistic regression analysis showed that the risk factors of males' genitourinary diseases included older age (OR=1.048, 95%CI: 1.007-1.091), higher pesticides exposure classification (OR=5.11, 95%CI: 1.313-19.890), more types of mixed pesticides (OR=3.243, 95%CI: 1.056-9.959), and more proportion of mixed pesticides (OR=0.697, 95%CI: 0.491-0.989), and higher frequency of eating meat per week (OR=0.697, 95%CI: 0.491-0.989) was a protective factor.
Conclusion A higher self-reported prevalence rate of genitourinary diseases is found in female vegetable greenhouse growers in Yinchuan. Deficiency of correct pesticides usage knowledge and related protective measures are the main influencing factors.
