Abstract
ObjectiveTo investigate influencing factors of brucellosis infection in occupational population in Gansu Province.
MethodsIn Jingyuan County of Gansu Province, using the case-control method, the cases were collected through "National Disease Surveillance Information Reporting Management System", the case group was confirmed as brucellosis professionals after laboratory tests were positive in 2013-2015 (203 cases), and the control group was confirmed as occupations without brucellosis (809 cases) in the same periods. Information on general sociological characteristics and occupational exposure characteristic was collected, non-conditional Logistic regression analysis was used for analyzing influence factors of brucellosis.
ResultsA total of 1 012 questionnaires were collected, among them, 203 were case group and 809 were control group. Logistic regression analysis showed that, captive (OR= 1.971, 95%CI: 1.193-3.256), type of water source (lage, OR= 1.610, 95%CI: 1.392-1.950), often stripping the dead lamb (OR= 2.027, 95%CI: 1.272-3.231), processing abortion material (throwing away, feeding the dog, stripping; OR= 2.120, 1.176, 2.160; 95%CI: 1.274-3.731, 1.148-2.134, 1.548-4.671), often eating dead meat (OR= 2.497, 95%CI: 1.438-4.339), Hui nationality (OR= 1.202, 95%CI: 1.061-1.995), household income less than 10 000 yuan (OR= 3.857, 95%CI: 1.593-9.336), work experience 1-4 years (OR= 2.892, 95%CI: 1.838-4.552) were major risk factors for occupational persons suffering from brucellosis. Livestock was sheep or sheep and goats (OR= 0.412, 0.277, 95%CI: 0.217-0.782, 0.107-0.720), married (OR= 0.124, 95%CI: 0.016-0.979), wearing gloves and mask when exposed to livestock or livestock lambing (OR= 0.455, 95%CI: 0.230-0.899), and livestock vaccination (OR= 0.283, 95%CI: 0.107-0.747) were protective factors for occupational infection of brucellosis.
ConclusionsThe poor living habits and behaviors of professional people in Jingyuan County of Gansu Province are the main causes of the disease. Among them, captive, often stripping the dead lamb, processing abortion material, eating dead meat are the risk factors for brucella infection. Wearing masks and gloves when livestock lambing, and livestock vaccination are important means in avoiding brucellosis infection.
