Aims: To test the triangle of human ecology by examining associations between unipolar depression and different measures of human biological factors, health behavior, and the physical environment.
Methods: Data originate from the third wave of the Nord-Trøndelag Health Study (2006-2008). The survey was based on a random sample of 50,000 Norwegians (response rate: 54 %). Logistic regression was preformed, using unipolar depression, measured with the HADS-score, as outcome variable and 38 explanatory variables.
Results: Biological factors including older age and male gender were associated with higher odds of depression as were behavioral factors including drinking behavior and having a neurotic personality. Reduced odds were associated with units of alcohol consumed, extrovert personality and physical activity. Social networks were an environmental factor with reduced odds at both personal and neighborhood levels, as was warmer outdoor temperatures.
Conclusion: Using the triangle of human ecology provides a holistic insight into how behavior, biology and the environment influence mental health.
