A Case Control Study: Physiological Aspect of Housing in the Relationship with Incidence of Tuberculosis in Tulungagung District East Java
About one-third of the world's population has been infected by Mycobacterium tuberculosis. Indonesia is the third largest TB cases in the world. Tuberculosis Eradication Program has been implemented with a DOTS strategy but TB cases in Indonesia are still high. Many factors caused high rates of TB incidence in Indonesia but most of them can be modified. Physiological aspect of housing is one of them which can be modified. This study objective is to analyze the relationship between physiological factors of housing with the incidence of pulmonary TB in Tulungagung District in 2016. This study is a case control that located in 2 health centers. Observation was carried out in February. Samples were selected by consecutive sampling with inclusion criteria: male (>18 years old) and if there are ≥2 male head of family in a house, researcher choose one randomly. Sample size were 64 participants which consist of 32 participants of case group and 32 participants of control group. Data was analyzed by chi square test. Results showed that there were significant correlation between dwelling density (OR=1.9; 95%CI: 1.2-3.0; p=0.00), lighting (OR=9.5; 95%CI: 3.0-30.4; p=0.00) and ventilation (OR=7.7; 95%CI:2.5 – 23.2; p=0.00) with tuberculosis incidence. It is recommended to improve quality of environment needs to be measured.
