De Quervain’s Disease among Motorcycle Repair Mechanics and Related Factors

Abstract

Introduction: Work-musculoskeletal disease is still an occupational health problem worldwide that
needs to be investigated in every different type of work.
Objectives: Identify De Quervain’s disease (DQD) prevalence on motorcycle repair mechanics and it’s
risk factors.
Methods: A cross-sectional study on 60 motorcycle repair mechanic in Samarinda city of Indonesia.
To determine DQD, a Finkelsteins test was performed. Age, education background, working period,
working time per day, and frequency of repetitive motion of the mechanic were collected by direct
interview. The number of samples using the Lemeshow formula. Phi coefficient test is applied to
identify the correlation between DQS prevalence and other parameters.
Results: the DQD prevalence of 63.3% was found, occurred in right and left hands, 36 and 24%,
respectively. It correlates significantly with age (p=0.047, r=0.346), working period (p=0.000,
r=0.861), education background (p=0.045, r=0.367), working time per day (p=0.055, r=0.616), and
frequency of repetitive motion (p=0.004, r=0.374).
Conclusions:The prevalence of DQD in motorcycle repair mechanics is quite high and requires
attention, prevention and control from stakeholders so that the prevalence does not increase.
