Abstract:
Objective To study the influencing factors about brucellosis in western Liaoning province (Linghai, Chaoyang, Xingcheng, Suizhong and Huludao City), and provide a scientific basis for further developing prevention and intervention measures.
Methods A questionnaire survey was conducted by a simple random sampling method among occupational groups such as people who feeding, selling and slaughtering livestock, and veterinarians, etc. in western Liaoning area. The data were analysed by chi-square test and multivariate non-conditional Logistic regression.
Results There were 98 patients with brucellosis among a total of 1 740 surveyed people, and the total prevalence rate was 5.63 percent. The prevalence rate of the group which had contacted with abortive livestock was higher than that of the non-contacted people (P < 0.001). The prevalence rates of brucellosis were significantly different among the surveyed people with different age, education level and occupations (P < 0.001). Altogether 10 risk factors which probably influenced the prevalence were found by chi-square test. Based on the multifactor non-condition Logistic regression analysis, 6 risk factors were significantly associated with the Brucellosis, which included raising livestock but without immunization (OR=12.756), not degerming (OR=5.303), not wearing the protective clothing or gloves (OR=3.265), not detoxicating the animal excrement (OR=3.129), contacting with abortive livestock (OR=2.892), and not quarantining when buying the livestock (OR=2.549).
Conclusion Lack of knowledge about brucellosis and self-protection consciousness, as well as having bad habits and behaviors were important reasons for brucellosis infection.
