Background: The co-occurrence of diabetes mellitus (DM) and tuberculosis (TB) is largely associated with high frequency of
Objective: To determine the prevalence of DM among TB patients and describe the socio-demographic and behavioral factors
associated with TB-DM co-occurrence .
Methods: We enrolled 500 TB patients from September, 2014 to August 2015 at four major public sector hospitals of Lahore,
Pakistan. A questionnaire was used to collect information regarding associated socio-demographic and behavioral factors of the
patients. We monitored the fasting blood sugar of each patient by using a semi automated clinical chemistry analyzer followed
by an HbA1c level check of all hyperglycemic patients.
Results: The prevalence of TB-DM co-occurrence was 14.8%. The prevalence of TB-DM was higher (62.2%) among males.
The >57 year age group had the highest proportion of patients (35.1%), with co-existent TB-DM. Most were illiterate (73.0%)
and unemployed (48%). Moreover, among the 74 patients positive for TB-DM had a history of smoking. Age and education
level were significantly associated with DM-TB while gender, occupation and smoking were not associated.
Conclusion: The study revealed a 14.8% prevalence of DM among TB patients. This was associated with several socio-demographic
factors, including age, unemployment, literacy and polluted environment. Thus, poor and unhealthy lifestyles were the
factors associated with DM among immunologically compromised individuals due to TB.
