Tuberculosis and associated risk factors among children and adolescent population in Serbia: 12 year's retrospective study

Recognition and epidemiological control of childhood and adolescent tuberculosis (TB) is essential to achieve effective control of TB in general as it presents high risk for transmission in the community. The aim of the study is to provide a descriptive and analytic overview of the trends in childhood and adolescent TB notifications and treatment outcomes and to identify factors associated with treatment success in a twelve-year period in Serbia. We performed a retrospective trend analysis and analysis of treatment outcomes of 596 child and adolescent TB cases notified in Serbia in the period 2005-2016 from all health facilities, as well as logistic regression analysis to identify predictors of treatment success. Factors independently associated with treatment success were: new TB (OR=2.60; 95% CI: 1.45-3.74), male sex (OR=2.55; 95% CI: 2.09-3.00), pulmonary TB (OR=3.34; 95% CI: 2.34-4.34), comorbidities (OR=2.58; 95% CI: 2.24-2.91), age below 5 years (OR=0.37; 95% CI: 0.32-0.43), and social vulnerability (OR=0.40; 95% CI: 0.34-0.46). In order to improve TB treatment outcomes among children and adolescent population in Serbia, it is important to focus on female, age group 5-18, EPTB, retreatment cases and socially vulnerable groups.
