Introduction China has the largest greenhouse production area in the word, with the rapid development of Ningxia facility agriculture, some greenhouse growers use the pesticides blindly in order to eliminate pests and increase economic efficiency. However, they are lack of the knowledge about how to use the pesticides and the individual protection consciousness of them are not high. We need to evaluate the genitourinary system health of vegetable greenhouse growers and analyse related influencing factors so as to protect these occupational population and improve their health. Methods Adopted the methods of whole group sampling at random studied on vegetable greenhouse growers in three districts and two countries of suburb in Yinchuan, collected the basic information and the pesticide exposure intensity by questionnaire. Used the logistic regression analytic method to each factor, found the influencing factors of the current state of genitourinary system in vegetable greenhouse growers, during April 2015 to May.

The genitourinary system prevalence rate reached 75.8% in the female growers. The results of multiple logistic regression analysis showed that increased the frequency of crop-spraying (OR=3.683) and chatting during crop-spraying (OR=2.532) were risk factors, while using abamectin (OR=0.311) was a protective factor. The genitourinary disease prevalence rate was only 14.11% in the male growers. The results showed that the risk factors of male genitourinary system health included age (OR=1.048), pesticides exposure classification (OR=5.11), types of mixed pesticides (OR=3.243), and the proportion of mixed pesticides (OR=0.697).
