| ObjectiveThrough the survey of Mongolian primary and secondary school students in Abaga Banner,Xilinhot City,Central Inner Mongolia,and Zalut Banner,Tongliao City,Eastern Inner Mongolia,using questionnaires and serological examinations,the primary and secondary school students’ understanding of brucellosis-related knowledge was counted,and students and sheep were sorted out.The behavioral habits in the contact process,analyze the knowledge of different demographics and the ways of brucellosis exposure,clarify the methods of behavioral intervention for students,provide data support for the publicity and education of brucellosis-related knowledge in schools,and realize the effective spread of brucellosis control.MethodsIn October 2019,one banner county(Abaga Banner and Zalut Banner)was selected from Xilinhot City and Tongliao City respectively,and convenience sampling methods were selected in two Mongolian schools in the two banner counties.Questionnaires and The method of serum examination is investigated.The content of the questionnaire mainly involves demography,knowledge of brucellosis,and behaviors during contact with sheep.Perform statistics on the data and analyze whether the data conforms to the normal distribution.If the data is normally distributed,use the mean±standard deviation form to explain;if the data present non-normal distribution,use the interquartile range(median Use the composition ratio and rate to describe the classification data;use the χ~2 test to achieve the comparison of the enumeration data between groups,and use Logistic regression analysis for multiple factors.Results1.A total of 1,050 questionnaires were sent out in this study,and 1,050 questionnaires were recovered.Questionnaires with incomplete answers or lack of serum test samples were excluded.There were 990 qualified questionnaires remaining,and the questionnaire efficiency reached 94.29%.Among the 990 people who provided qualified questionnaires,498 were male students and 492 were female students.The male-to-female ratio was 1.01:1;the youngest was 11 years old and the oldest was 19 years old.Among them,14-16 years old have the largest number of students,accounting for the total number of students.54.14% of the total.2.Among the 990 primary and middle school students,the number of "hearing others talk about brucellosis" was 421,accounting for 42.53% of the total.The main way and channel for knowing brucellosis is "listening to village doctors or acquaintances",accounting for 34.55% of the total number of people(342/990),followed by "watching TV and listening to radio propaganda",accounting for 13.94% of the total number of people(138/990),the proportion of the total number of people through the "school health education method" is10.91%(108/990).3.The correct rate of answering 25 questions about three aspects of brucellosis-related knowledge of students was 14.68%,and the correct rate of answering the three questions of "animal infection of brucellosis","human infection of brucellosis" and "prevention of brucellosis" was 14.68% The order is 15.52%,13.01%,17.80%.The correct answer to the question of the infected population among primary and middle school students was 67.22%,and the correct answer rate of the uninfected population was 13.61%.The correct answer rate of infected people was higher than that of uninfected people(χ~2=850.187,P <0.001).4.Different age groups have statistical significance in the three aspects of "animal infection of brucellosis","human infection of brucellosis" and "prevention of brucellosis"(P<0.05);there is no statistical significance for different genders;different regions There were statistical differences in the awareness rate of 22 questions(P<0.05).5.The scores of 25 questions in the three areas of "human brucellosis","animal brucellosis" and "brucellosis prevention" are counted.The minimum score of 0 is 10.40%(103/990)and the maximum is 11 points.The ratio was1.62%(16/990),and the median score was 4 points.The qualified number(reaching 7 points and above)is 220,and the qualified number accounts for 22.22%(220/990)of the total number.6.Comparison of the differences in contact rates between different demographics and sheep contact methods.There are differences in the contact rates among students of different genders in holding lambs,milking them,vaccinating sheep,feeding sheep,and cleaning sheep pens(P< 0.05);the contact rate of holding lambs,milking,vaccinating the sheep,feeding the sheep,and cleaning the sheep pen is different among students of different age groups(P<0.05);helping to deliver the sheep and dispose of the lambs Or abortion,lamb handling or abortion,lamb holding,milking,helping feeding,cleaning the sheep pen,there is a statistical difference(P<0.05);the contact rate of students with different residence years and the way of contact with the sheep is quite different,and there are statistics.The difference in science(P<0.05);the contact rate of vaccinating sheep and feeding sheep was statistically different between those who scored qualified and unqualified in the awareness question(P<0.05).7.In the investigation of behavior habits,the higher contact rates were lamb holding,feeding of sheep and cleaning of sheep pen,the proportions reached 67.37%(667/990),61.11%(605/990)and 52.22% respectively(517/990),followed by milking 17.07%(169/990),delivering sheep 16.06%(159/990),vaccinating sheep 12.12%(120/990),and disposing of lambs and liquid products 11.72%(116/990),the lower contact rate is 8.18%(81/990).Brucellosis infection is statistically associated with handling of lambs or sludge,milking and vaccinating sheep(χ~2=70.558,P <0.001;χ~2=87.556,P <0.001;χ~2=90.448,P <0.001).Multivariate logistic regression analysis showed that the independent risk factors for brucellosis were treatment of lambs or flow products OR=4.798,95%CI(1.844-12.480),milking OR=5.722,95%CI(2.354-13.908)and feeding sheep Vaccination OR=4.137,95% CI(1.629～10.506).Conclusion1.The way that Mongolian primary and middle school students learn about brucellosis is generally introduced by doctors or familiar people in the village.School health education is not the main way for students to learn about the knowledge.2.The awareness rate of brucellosis-related knowledge among Mongolian primary and secondary school students is low,and the awareness rate of infected people is higher than that of uninfected people.The awareness rate of brucellosis-related knowledge was higher in the14-16 years old age group and the 17-19 year old age group than the 11-13 year old age group.3.Mongolian elementary and middle school students often come into contact with sheep.The most common contact methods are lamb holding,feeding of sheep,sanitary cleaning of sheep pens,infection and treatment of lambs or effluents,milking and vaccinating sheep related. |
