RESUMO
@# Objective To understand the medical intention and influencing factors of middle school students with suspected tuberculosis symptoms in some areas of China and to analyze the influencing factors based on health belief model. Methods A total of 2 547 middle school students in six provinces of China were chosen by PPS sampling method. Logistic regression was used to analyze tuberculosis medical intention.based on health belief model. Results Female students, urban students, eastern students and residential students had higher degree on knowledge than other respondents in the same group, which had statistically significant difference(all P<0.05). Middle school students in the western region had a higher degree of perceived disease threat, boys and middle school students in the eastern region were more likely to be reminded and accompanied by family members and friends. The delay rate was 25.4% when students have continuous cough and expectoration more than two weeks. In terms of logistic regression analysis, gender (OR=0.809, 95% CI:0.668-0.980), urban and rural (OR=0.692, 95% CI:0.572-0.838), only-child (OR=0.819, 95% CI:0.676-0.992), perceive the severity of the disease(OR=0.955, 95% CI:0.922-0.989)and prompt factors(OR=0.514, 95% CI:0.429-0.617) were the influencing factors of the tuberculosis medicial intention. Conclusions The health belief model could analyze and explain the influencing factors that affect the tuberculosis medical intention of middle school students in some way. Health education should be strengthened and health behaviors should be advocated according to the characteristics of different groups.
