The study was conducted in the Jajmau area of Kanpur and interviewed 284 tannery workers selected using scientifically developed study design using probability sampling approach. Univariate and bivariate analyses were used to assess the prevalence and intensity of LBT. Logistic regression analysis was used to identify the potential risk factors for contracting LBT.

Among the workers aged 35+years, about a sixth (16%) reported daily recurrence of pain, and about a fifth (19%) experienced pain more than 10 times in the last 12 months. Tannery workers who were injured at work in the last 12 months was 2.09 and 2.42 times more likely to get LBT in Model-II and III.
