Participation in pooled analyses
 

  • The cohort is potentially interested in participating in pooled analyses of (European) occupational cohort studies (note pooled analyses also includes remote decentralized analyses that would not require any transfer of primary data as well as meta-analyses).
Main aim of cohort, please briefly describe the main objectives of the cohort
  The aim was to estimate prevalence rates of musculoskeletal disorders and their risk factors in the regional workforce according to age, gender, economic sector and occupation and to assess the occupational risk factors of musculoskeletal disorders..

2. OUTCOME FOLLOW-UP
Type of data for outcome follow-up (please select as many as appropriate)
 

  • Active (contact with participants)
Active (contact with participants) (specify)
 

  • In 2007, a follow-up questionnaire was mailed to subjects. In the case of non-response, they were sent two successive reminder letters with the self-administered questionnaire. If their address was unknown, the new address was sought by contacting either their OP or the French public postal services. For workers who had not returned the self-administered questionnaire in 2007, the occupational physicians were asked to pass on the questionnaire to the workers during a regular health examination in 2008 and 2009.
  • Between 2007–2010, medical follow-up of the workers initially included was undertaken . Retired people, people on parental or long-term sick leave, and unemployed people were excluded. Several reminders were sent out to all occupational medicine services, and then to each OP now responsible for the medical surveillance of at least one worker of the cohort. For workers who had changed OP, the research team systematically contacted the last OP responsible for their medical surveillance.
First follow-up period (provide year)
  2007-2009
Last follow-up period (provide year)
  2007-2010
Number of follow-ups after baseline (provide number)
  2
Participation at last follow-up (if known)

Comments
  One follow-up by self-administered questionnaire (n=2332) and one follow-up by physcial examination (n=1611)
1,175 were followed by self-administered questionnaire and physical examination
The follow-up period coincided with a major economic crisis in the region during 2008–2009, when the regional salaried workforce declined by 3.4%, and even by 33.7% in temporary employment agencies according to the French Economic Institute.
