Background:-Injury is a major public health problem. In India, it accounts for 15% of total deaths and 15% of disability adjusted life year, resulting in 3% of GDP loss for a country. Aim: - To assess the prevalence of injury and its mechanism in Bommanahalli, Bangalore. Methodology: - The study setting included Bommanahalli, a semi urban area in Bangalore with a population of two and half lakh and 21 sub areas. A sample size was determined to be 174 households (WHO __ampersandsignndash; Guidelines for conducting community surveys on injuries). A two stage cluster sampling technique was used. In the 1st stage, 6 clusters (sub area) were randomly selected. In the 2nd stage households were systematically selected till the desired household is obtained (29 households). An interview was done with the household member for demographic details, injury and its mechanism and its impact for the past one year. Descriptive statistics like mean, standard deviation, cross stabs and contingency coefficient were used. Results: - A total of 220 households were approached and 174 responded, with a response rate of 79%. This resulted in 753 persons with an age ranging from 1year to 76 years with a mean age of 26.7 years (__ampersandsignplusmn; 15.56). In 753 persons, 52 (6.9%) had some form of injury. Analysis of mechanism of injury showed that 40.4% (21) was due to road traffic accidents and 3.8% (2), 9.6% (5), 7.7% (4), 7.7% (4), 3.8% (2), and 15.4%(8) constituted for fall, struck/hit by person or object, stab, fire, poisoning, animal bite respectively. Majority of the injuries 84.6%(44) were unintentional; 5.8% (3) and 7.7%(4) accounted for intentional and self-inflicted injuries. 38.2%(21) of the injured persons had physical disabilities like unable or difficulty in using the arm, loss of vision, hearing etc. 12.7%(7) of the injuries were medico legal, 7.3%(4) of the family members had left job to take care of the injured person.
