Background & ObjectivesDisability-adjusted life years (DALYs) have been accepted as a useful method to estimate the burden of disease, and can be adapted to determine the number of productive years lost due to the disability. DALY has been reported for many studies but not for leprosy. Hence this study was carried out in three States of India. In view of the fact that in this study, productive working years are used, the term is modified as DAWLY.MethodsA representative random sample of 150 leprosy affected persons, 50 from each States of Uttar Pradesh, West Bengal and Chhattisgarh, was chosen, and data were collected on detailed work-life history, occupation, time when leprosy was discovered, reported and treatment started, break of job/loss of income due to leprosy. The loss of wages and durations were used to compute the life-years lost due to leprosy, and summarized over the average total duration of 42 years of productive work-life from 18 to 60 years. The percentage losses were determined and differences tested for statistical significance.ResultsThe overall mean (± SE) disability adjusted working life years was 28.6 (±0.67), a reduction of 13.4 yr from the ideal productive working life period of 42 yr. The youngest patients with disability had a reduction of 41.4 per cent, as compared to the oldest patients. There was a significant increase in loss based on year for those whose disability started earlier (P=0.0024).Interpretation & ConclusionsOn an average, 30 per cent of the leprosy affected person's work life is lost due to disability.
