Transcript

  • 1. European Validation of a Job Exposure Index based on ISCO-88 and KldB-92 Dr. Lars Eric Kroll The Robert Koch Institute is a Federal Institute within the portfolio of the Federal Ministry of Health
  • 2. Background Source: Kroll 2011 (bit.ly/1gBpVJ8 )  For population-representative studies, there are few tools that enable an approximate collection of work related risks.  Therefore, a score for the approximation work related risks applicable via standard classifications of occupations (ISCO-88, KldB-92) in any study was developed.  Due its, which was done using multi-level regression models, the Index is statistically robust can be used even for rare occupations.  The index is based on a large employment survey of 2006 and is published by the GESIS  The Index is openly accessable over the Internet (for free in scientific studies).

  • 3. Index Domains
  • 4. Perception risks at work Source: Kroll (2011), GEDA 2009, % stating own health heavily at risk due to work
  • 5. Mortality of men Source: Kroh et al. (2012), SOEP 1984-2012, Alter 65+
  • 6. Aims of the current study 1. Is the index a predictor for work related health risks in other European countries? 2. For which outcomes? 3. Are there gender differences regarding ist predictive ability in Europe?
  • 7. European Working Conditions Survey The European Working Conditions Survey (EWCS) is conducted by the European Foundation for the Improvement of Living and Working Conditions (EFILWC), which is an autonomous agency of the European Union (EU), funded from the general budget of the European Commission. Past and current survey • First EWCS in 1990/1991: workers in the EC12 were surveyed • Second EWCS in 1995/1996: workers in the EU15 were surveyed • Third EWCS in 2000: the EU15 and Norway were surveyed in a first phase, the survey then being extended to cover the 12 “new” Member States in 2001, and Turkey in 2002 in a second phase • Fourth EWCS in 2005: EU27, plus Norway, Croatia, Turkey and Switzerland • Fifth EWCS 2010: 44,000 workers interviewed in the EU27, Norway, Croatia, the former Yugoslav Republic of Macedonia, Turkey, Albania, Montenegro and Kosovo.
  • 8. EWCS 2010 Referenced Population: 216 million people aged 15+ and employed (according to ILO definition) in the EU27 Methods: CAPI; Field Time from January to June 2010 conducted by Gallup Europe Sample Size: 43,816 workers from 34 European countries Translation Process: Master National translators (2)  comined version  ReTranslation  Evaluation nat. and int. Experts  Final Version (32 languages) Cooperation Rate and Response Rate: 63% Cooperation Rate; 48% Response Rate Availability: UK Data Archive
  • 9. EWCS 2010: Currently Working
  • 10. Outcomes  Health Risks Do you think your health or safety is at risk because of your work? Yes vs. No/Don’t know – no opinion  Health Status How is your health in general? Would you say it is … Fair/Bad/Very Bad vs. Good/Very Good  Health affected by work Does your work affect your health, or not? Yes, mainly negatively vs. No, not at all/Yes, mainly positive  Symptom Score Over the last 12 months, did you suffer from any of health problems? 5 to 14 symptoms vs. 0 to 4 symptoms
  • 11. Sample Characteristics Data: EWCS 2010, currently working, age 18 to 64 years (n= 40.440) Missing Values: None 94,3%, one 4.8%, more then one 0.9%
  • 12. Variation of OJI by EWCS 2010 Country Data: EWCS 2010, currently working, age 18 to 64 years (n= 40.440)
  • 13. Aggregate Level Association of OJI, Risks and Health Data: EWCS 2010, currently working, age 18 to 64 years (n= 40.440)
  • 14. Individual Level Association of OJI, Risks and Health Data: EWCS 2010, currently working, age 18 to 64 years (n= 40.440) OR=6,7 OR=4,1 OR=2,6 OR=2,3
  • 15. Logistic Multi-Level-Regression on Outcomes Data: EWCS 2010, currently working, age 18 to 64 years (n= 40.440) Health Risks Gender Men Women Job Risk Index (OJI) low medium high Interaction OJI x women low x women medium x women high x women MOR for country Health affected OR p Ref. 0,63 0,00 OR Ref. 0,81 Ref. 2,43 0,00 4,26 0,00 Ref. 1,65 2,70 Ref. 1,07 0,50 0,94 0,54 1,52 0,00 Ref. 1,08 0,96 1,58 p Health Status 0,01 OR Ref. 1,04 0,00 0,00 Ref. 1,18 1,61 0,35 0,68 0,00 Ref. 1,13 1,32 1,76 *Controlled for education, working hours and years on the job p Health problems 0,66 OR Ref. 1,50 p 0,00 0,01 0,00 Ref. 1,39 1,83 0,00 0,00 0,16 0,00 0,00 Ref. 0,95 1,03 1,46 0,51 0,75 0,00
  • 16. Conclusion  The index for general stress at work is a good indicator of work stress and health risks at work.  The index was validated externally several times for Germany.  In a European comparison, the index was a significant predictor of work stress, regardless of gender and country.  It can be used in epidemiological studies as an alternative to a dedicated collection of work related exposures.  It should be used primarily as a control variable for occupational exposures.
