Completed

• Conditions: Chronic Disease
• Interventions: Other: No intervention

• Registration Number: NCT03013725
• Lead Sponsor: University of Bergen

Brief Summary

The Hordaland Health Studies (HHS) were conducted in 1992-93 (The Homocysteine study) and in 1997-99 (HUSK). Both surveys were conducted as a joint project between the University of Bergen, the Norwegian Health Screening Service (SHUS) (now part of the National Institute of Public Health) and the Municipal Health Service in Hordaland.

The main focus of the studies is on chronic diseases including cardiovascular disease, cancer, osteoporosis, anxiety and depression. Some projects focus on psychosocial factors, occupational research, musculoskeletal diseases, urinary incontinence and mapping of drug use. The main purpose of the surveys is to gather information so that disease ultimately can be prevented.

Approximately 36,000 residents of Hordaland county participated in the studies, ca. 18,000 in 1992-93 and ca. 26,000 in 1997-99. About 7,000 of those who participated in the 1992-93 survey also participated in 1997-99.

The Homocysteine Study	No intervention	Conducted in 1992-93, ca. 18000 participated.

Primary Outcome Measures

Name	Time	Method
Total mortality.	Participants are followed from baseline (1992-93 or 1997-99) until death or December 31st, 2015.	The unique 11-digit personal identification number assigned to all Norwegian residents facilitates linkage between HHS and the Norwegian Population Register, which contains information on vital status (alive, emigrated, or dead). The follow-up period varies from 16 - 23 years, depending on whether first or second measurement is used as baseline.

Secondary Outcome Measures

Name	Time	Method
Mortality or morbidity from chronic diseases (for example cardiovascular disease, cancer). Also, award of disability pension are used as an outcome.	Participants are followed from baseline (1992-93 or 1997-99) until time of diagnosis/death from disease or the last day of follow-up.	The Cause of Death Registry, Cancer Registry of Norway, CVDNOR and FD-trygd (a national database of Health and social benefits) will be used to get information on outcomes. The last day of follow-up for cardiovascular disease is December 31st, 2014. The last day of follow-up for cancer is December 31st, 2014.; The last day of follow-up for Cause of Death is December 31st, 2014. The follow-up period for cardiovascular disease varies from 15 - 22 years, depending on whether first or second measurement is used as baseline.; The follow-up period for cancer varies from 15 - 22 years, depending on whether first or second measurement is used as baseline.
