Non-communicable diseases and risk of tuberculosis in Korea.
It is possible that the increasing burden of non-communicable diseases (NCDs) and their risk factors are an obstacle to the reduction of tuberculosis (TB) incidence in the Republic of Korea.



To estimate population-attributable fractions (PAF) of NCDs and their risk factors related to TB in Korea.



The prevalence of diabetes mellitus (DM), current smoking, heavy drinking and undernutrition was estimated from the Korean National Health and Nutrition Examination Survey (KNHANES) conducted in 2013. Estimates of effect for risk factors were obtained from meta-analyses. The PAF was calculated based on these data.



The PAF of DM, current smoking, heavy drinking and undernutrition was 20.0%, 18.8%, 18.4% and 9.6%, respectively. Current smoking has the highest PAF among men, while undernutrition was the highest among women. Current smoking and heavy drinking were significantly attributed to TB among the younger population, while DM was the most common responsible factor among the older population. Major risk factors such as current smoking and DM were more prevalent in the lower income level population.



NCDs and their risk factors play an important role at the population level in TB epidemics in Korea. Collaborative TB and NCD activities in TB control should therefore be intensified.
