Background: Tuberculosis (TB) remains a leading cause of morbidity and mortality in developing countries, including Indonesia. This study aimed to determine the effects of nutritional status and dwelling density on the risk of pulmo­na­ry TB incidence in Medan, North Sumatera.

Subjects and Method: This was a case-control study conducted at Pulmonary Di­­sease Hospital, Medan, North Sumatera, from January to June 2018. A sample of 116 patients was selected for this study, consisting 58 patients with TB and 58 pa­­tients without TB. The dependent variable was TB incidence. The independent va­­riables were nutritional status and dwelling density. Data on TB case were obtained from the medical record. Nutritional status was measured by Body Mass In­­dex (BMI). Dwelling density was measured by observation. The other data were collected by questionnaire. The data were analyzed by a multiple logistic regression.

Results: The risk of lung TB increased with low nutritional status (OR=3.07; 95% CI= 1.40 to 6.73; p= 0.005) and dense dwelling (OR= 2.83; 95% CI= 1.29 to 6.21; p= 0.009).

Conclusion: The risk of lung TB increases with low nutritional status and dense dwelling.

Keywords: nutritional status, dwelling density, lung tuberculosis
