Abstract
IRIBARREN and colleagues, Division of Research, Kaiser Permanente, Oakland, CA, USA, dgi@dor.kaiser.org, present the CARDIA study on the relationship between the intake of n-3 and n-6 fatty acids and hostility in young adults.
Background
Hostility has been shown to predict both the manifestation and development of heart disease. It therefore seems worthwhile to study the relationship between dietary intake of cardioprotective polyunsaturated fatty acids and hostility.
Methodology
In this cross-sectional observational study (part of an ongoing cohort study), 3581 urban black and white young men were analyzed for their dietary habits and hostility levels.
Results
After correction for age, gender, race, field centre, education, marital status, body mass index, smoking, alcohol consumption, and physical activity, the odds for scoring high in hostility are lowered to 0.90 for each standard deviation increase of docosahexaenoic acid intake. Equally, the consumption of fish rich in polyunsaturated fatty acids, as compared to no fish, lowers the odds of scoring high in hostility.
Conclusion
These results suggest that eating oily fish is associated with decreased hostility in young men. This highly interesting association merits further research.
