Beskrivelse af JEM

Name: Lower Body JEM

Exposure: Expert rated exposures in 5 domains:

  1. Standing/walking (hours per 8 hours workday)
  2. Kneeling/squatting (hours per 8 hours workday)
  3. Whole body vibration (hours per 8 hours workday)
  4. Total load lifted (kg/day)
  5. Frequency of lifting loads weighing ≥20 kg (times/day)

Coverage: 122 homogeneous groups, covering all occupational titles in The Danish version of ISCO-88 (DISCO-88) and their corresponding DISCO-88 codes. Of the 372 DISCO-88 codes, 204 were assessed as minimally exposed on a general level. The remaining 168 DISCO-codes were allocated to 121 homogeneous groups.

Job title and industry classification system: DISCO-88 (including all codes). The conversion between the version based on occupational titles and the version based on DISCO-88 codes is described in (Vad et al., 2012).

Calendar period: The JEM was established in 2009 and should cover a time period from around 1990 to the present date.

Uncertainty in exposure measures:
The exposures were expert assessed. Experts agreed on rankings of job groups, and rankings based on mean values of the experts’ rating were in accordance with the opinion of external experts.

Demographic dimensions:
No demographic dimensions.

Forskningsprojekter om fysisk belastning i DOC*X

Inden for DOC*X er der flere projekter, som forsker i sammenhængen mellem fysisk belastning og sundhed, hvor jobeksponeringsmatricen Lower body JEM benyttes som eksponering.

Der foretages blandt andet forskning, som forsøger at forbedre forebyggelsen af alvorlig lænderygsygdom som følge af fysiske belastninger på arbejdspladsen. I dette forskningsprojekt sættes der særligt fokus på degenerative forandringer og diskusprolapser i lænderyggen. Anden forskning sætter specifikt fokus på faggruppen fiskere, og behovet for mere viden om om deres sundhedssituation i forhold til deres erhverv. Blandt andet hvilke faktorer der i fiskernes arbejdsliv kan forudsige muskuloskeletale sygdomme og hvordan det er muligt at reducerer forekomsten af muskuloskeletale sygdomme og symptomer blandt fiskere.

Dette er blot få eksempler på den forskning, som foretages i DOC*X regi. Her kan du se mere information om andre forskningsprojekter, som benytter DOC*X data.
