Higher risk of developing active TB among adult diabetics exposed to TB during childhood: A study from Kerala, India.

Introduction: Factors associated with tuberculosis (TB) in Kerala, the southern Indian state that notifies approximately 33 microbiologically confirmed new cases per 100,000 population every year for the past two decades, are still unclear. We did a community-based case-control study in Kollam district, Kerala, to identify the individual-level risk factors for TB.

Methods: Structured questionnaire was applied to 101 microbiologically confirmed new TB cases registered under Revised National Tuberculosis Control Program and 202 age- and gender-matched neighborhood controls without present or past TB.
