Data access policy (briefly describe)
|
|
access possible based on agreed co-operation in the analysis with FIOH
|
Is this cohort part of a consortium? (name consortium)

Working hours, health,, wellbeing and participation in working life (WOW, https://www.ttl.fi/en/research-and-development-projects/wow/)
|
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
|
|
Working Hours in the Finnish Public Sector (WHFPS) cohort has payroll-based data of daily working hours including information on absences due to various reasons such as sickness absence of over 200 000 employees in altogether 12 large hospital districts and 13 cities (including the five largest cities) in Finland since 2007-2008 up to 2020. The database is maintained by FIOH based on co-operation with Finnish health and social care organizations and CGI Finland. The main aim of the cohort is to investigate the association of nigh and shift work with health, well-being and other occupational outcomes.

This is an exposure database that can be linked any registry data on individual bases. We have linked it to surveys (FPS), occupaitonal injuries and morbidity data.

|
We are currenly working on the sickness absence, occupational injuries, breast cancer and the the effects of different software tools (e.g. participatory shift scheduling) on sickness absence and perceived health with co-operation with the Finnish Public Sector surveys (all those organizations are also part of this exposure cohort).
This payroll-based working hour data base can be linked on individual bases to any registry outcomes available in Finland.
