HUNT for better public health

Area of Science:

• Public Health Research
• Epidemiology
• Health Services Research

Background:

• The Trøndelag Health Study (HUNT) has collected decennial population data for four decades.
• HUNT has data from 240,000 participants, uniquely identified by Norwegian birth numbers for longitudinal tracking.
• This enables tracking participants across life stages and into national health registers without attrition bias.

Purpose of the Study:

• To provide a comprehensive overview of public health development over decades.
• To facilitate research in health services, clinical epidemiology, disease causation, and gene-environment interactions.
• To analyze population health trajectories and disease consequences.

Main Methods:

• Longitudinal population-based cohort study design.
• Decennial surveys collecting comprehensive health data.
• Linkage to national health registers for endpoint measures.

Main Results:

• Identified major public health trends: decreasing mean blood pressure and resting heart rate, increasing obesity.
• Revealed geographical and socioeconomic health inequalities.
• Documented increasing mental health distress in young people and opposite trends in the elderly.

Conclusions:

• HUNT data are valuable for international research collaborations and data harmonization.
• Emphasis on research ethics, privacy, and data security is paramount.
• Researchers can apply for data access through the HUNT Research Centre with ethical approval.
