Abstract Setting Tuberculosis (TB) and diabetes mellitus (DM) are prominent public health problems in the Republic of the Marshall Islands, a small island nation with high rates of tuberculosis and diabetes. Objective Evaluate the rate of active and latent TB in a Pacific Island DM clinic. Design In one DM clinic on the island of Ebeye, 213 adult patients aged 27–86 years completed tuberculin skin testing and TB work-up between April 2010 and March 2012. Results Screening for TB led to the diagnosis of 77 patients with TB infection and 11 patients with TB disease. From these data, the prevalence of TB disease among DM patients in the clinic exceeded 5% (95% CI 2.2%–8.1%). All patients who completed TB screening were at high risk of TB disease, and those with DM aged ≤ 50 years had a higher risk of TB disease than those with DM over age 50 (RR 3.1, C.I. 1.0–9.7, p = 0.05). Conclusion The experience at the Ebeye Diabetes Clinic demonstrates that screening DM patients for TB can identify significant rates of TB infection and TB disease, and should be considered for other settings with a high background TB incidence. Further assessment of TB risks should explore age, gender, and level of diabetes control.
