Epidemiology in a changing world: implications for population-based research on mental disorders

Area of Science:

• Epidemiology
• Psychiatric Epidemiology
• Public Health

Background:

• Population-based mental disorder research requires alignment with general epidemiology trends.
• Current psychiatric epidemiology faces challenges due to evolving epidemiological strategies and methods.
• Uncertainty in the parent discipline complicates the advancement of psychiatric epidemiology.

Purpose of the Study:

• To examine new strategic and methodological proposals in general epidemiology.
• To assess the significance of these proposals for psychiatric epidemiology.
• To identify future directions for psychiatric epidemiology research.

Main Methods:

• A narrative review of proposed epidemiological strategies and methods.
• Cross-checked by searching English-language epidemiology journals for trends from 2000 onwards.
• Analysis of three key proposals: eco-epidemiology, research translation, and global adaptation.

Main Results:

• Three main proposals identified: eco-epidemiology, improved research translation, and adaptation to a globalized economy.
• Eco-epidemiology integrates individual risk factors with macro-environmental systems.
• Research translation emphasizes faster implementation of evidence into policy and practice.
• Global adaptation calls for regulated funding and resources in epidemiology.

Conclusions:

• Proposed directions have significant implications for psychiatric epidemiology.
• Psychiatric epidemiology currently focuses on specific issues like definition and classification.
• There is a need for an eco-epidemiology model for psychiatric disorders, enhanced implementation strategies, and international collaborations.
