ObjectiveTo compare the performance of 36-item short form health survey (SF-36) and World Health Organization quality of life-bref (WHOQOL-Bref) in assessing quality of life (QOL) in patients with pulmonary tuberculosis (TB). MethodsThe WHOQOL-Bref questionnaire and the SF-36 questionnaire were administered to patients with tuberculosis undergoing treatment from July to September 2013. The statistical methods of reliability analysis, factor analysis and the Pearson correlation coefficient analysis were used. ResultsIt showed that the WHOQOL-Bref and the SF-36 both had good reliability (Cronbach α=0.863 and 0.920, respectively). Constructive validity of the two instruments were checked by factor analysis and the Pearson correlation coefficient analysis, which indicated that both the two instruments had good validity. Among scales measuring similar concepts, many subscales of the SF-36 and the four domains of the WHOQOL-Bref unexpectedly had a fair correlation with one another. For example, the physical QOL, psychological QOL, and social relation QOL domains of the WHOQOL-Bref and physical functioning, mental health, and social functioning of the SF-36 were 0.482, 0.745, and 0.572, respectively. ConclusionThe WHOQOL-Bref and the SF-36 have an approximately equivalent practicability in assessing the quality of life in patients with TB.
ObjectiveTo investigate the epidemiology of tuberculosis in Mianyang city, and investigate its risk factors to provide scientific evidence for tuberculosis prevention and management. MethodsA stratified cluster random sampling method was applied and 184094 residents were recruited in the study. The prevalence of tuberculosis was analyzed by questionnaires, physical examinations, X-ray, and laboratory tests. The risk factors of tuberculosis were analyzed by binary logistic regression method. ResultsOne hundred and seventy-five subjects were diagnosed with active tuberculosis, and the incidence of tuberculosis was 95.06 per thousand. There were 32 smear-positive pulmonary tuberculosis patients, and the incidence was 17.38/100 per thousand. Males, farmers and workers, diabetes, family history of tuberculosis, smoking, drinking were risk factors for tuberculosis. ConclusionsThe prevalence of tuberculosis in Mianyang city is similar with the whole country. Male, farmers and workers, diabetes, family history of tuberculosis, smoking, and drinking maybe the risk factors of tuberculosis.
ObjectiveTo understand basic characteristics and clinical features of tuberculosis in Mianyang, Sichuan, and to investigate the risk factors of two case-finding methods for tuberculosis:"passive finding" and "active screening". MethodsOne-hundred and seventy-five active tuberculosis patients screened by physical examination in 21 villages of Fucheng and Jiangyou from June 2013 to March 2014 were included. Information about basic characteristics and clinical features of tuberculosis was collected using questionnaire, chest X-ray and laboratory examinations. We also applied binary logistic regression to explore the risk factors of finding for tuberculosis. ResultsIn all 175 tuberculosis patients, 41.71% were over 60 years old and 73.71% were farmers. Productive cough over two weeks was the most common symptom, accountting for 58.29%. 19.63% were sputum smear-positive while 70.87% were PPD-positive. Binary logistic regression analysis demonstrated that tuberculosis history significantly influenced the findings for tuberculosis (OR=15.809,95%CI: 6.708~37.258). ConclusionsActive tuberculosis patients screened by physical examination in Mianyang, Sichuan were mainly elderly male over 60 years old and farmers, with single pulmonary symptom as the primary clinical feature. The patients with tuberculosis history may be found by "passive finding".
