title: [Clinical and social factors related with a long labor disability].
abstract: OBJECTIVE
  To determine the factors associated with a longer labor disability (LLD) due to a labor accident.
  
  
  METHODS
  A cases and controls study was made. All the patients who presented a disability certificate for over thirty days due to a labor accident were included. The socio-demographic, labor characteristics and diagnoses were analyzed. A bivariate statistical analysis was made.
  
  
  RESULTS
  There were 32 cases; average age was 34 years; 27 were men (84.4%) and 5 women (15.6%); the predominant schooling was the upper middle level in 40%, the economical level was poor in 40%, the 19.1% worked as a store assistant. The anatomic region most affected was the wrist-hand in 19 cases (27.9%) and the more frequent diagnoses were: injuries 33%, fractures 32.4% and inadequate skills 23.5%. Associated factors were the lack of training (OR: 1.6 IC: 1.08-2.47), working in the afternoon or at night shift (OR: 4.19 CI: 1.04-20 .07) and being a man (OR: 1.4 CI: 0.66-2.9).
  
  
  CONCLUSIONS
  It was observed that sex, not training and the schedule of working were associated with a LLD.
