Prevalence Of Diabetes Mellitus Among Tuberculosis Patients Attending PHC/TU/Dmcs In Rohtas District, Bihar

Abstract

Tuberculosis (TB) and diabetes mellitus (DM) co-morbidity is an emerging public health concern, with growing evidence identifying DM as an important risk factor for TB. This study aimed to estimate the prevalence of DM among newly detected sputum-positive pulmonary TB patients and to assess associated risk factors at PHC/TU/DMCs in Rohtas District, Bihar. This cross-sectional study was conducted from 2023 to 2025 at 18 PHCs, TUs, and DMCs in Rohtas among newly detected sputum-positive pulmonary TB patients for individuals aged 1-90 years. Diabetes mellitus was diagnosed using blood glucose levels ≥200 mg/dL measured by autoanalyser. Descriptive statistics, correlation analysis, and two-way ANOVA were applied, with p < 0.05 considered statistically significant.OPD attendance and population coverage increased significantly over the study period, indicating improved service utilization, though marked inter-centre disparities persisted. Suspected TB detection also increased over time, reflecting strengthened screening, but with significant variability across centres and in associated diabetes detection. Among 3,299 TB patients included, the prevalence of DM was 3.3%, substantially lower than reported in many other studies, possibly reflecting local population characteristics. Routine diabetes screening among TB patients is necessary for early detection and integrated management, which may reduce complications and improve TB treatment outcomes.
