Background: Tuberculosis (TB) remains one of the world’s deadliest com­mu­ni­cable diseases. In 2016, 10.4 million people fell ill with TB, and 1.7 million died from the disease (including 0.4 million among people with HIV). Over 95% of TB deaths occur in low and middle-income countries. Seven countries account for 64% of the total, with India leading the count, followed by Indonesia, China, Philippines, Pakistan, Nigeria, and South Africa. Given that most deaths from TB are pre­ventable, the death toll from the disease is still unacceptably high and efforts to combat it must be accelerated. This study aimed to determine the effects of con­tact history and family income on the risk of pulmonary TB in Padang­sidimpu­an, North Sumatera.

Subejcts and Method: This was a case control study conducted at several Puskes­mas (Community Health Center) in Padangsidimpuan, North Sumatera. A total of 90 patients consisting of 45 TB cases and 45 controls were selected for this study. The dependent variable was pulmonary TB. The independent variables were contact history and family income. Pulmonary TB cases were determined by spu­tum acid fast tuberculosis (AFT) bacilli test. The other data were collected by questionnaire. The data were analyzed by a multiple logistic regression.

Results: The risk of pulmonary TB increased with history of TB contact (OR= 4,01; 95% CI= 1.67 to 9.66; p= 0.002) and low family income (OR= 2.53; 95% CI= 1.07 to 5.9; p= 0.033).

Conclusion: The risk of pulmonary TB increases with history of TB contact and low family income.

Keywords: pulmonary tuberculosis, tuberculosis contact, family income.
