N2  - Evidence suggests that omega-3 fatty acids are important for a variety of mental health outcomes and have been shown to improve both mood and behaviors. However, there is little consensus on whether omega-3 fatty acids are beneficial for reducing aggressive behaviors. The current study assesses the relationship between omega-3 fatty acids and aggression. A total of 73 effect sizes were calculated among 40 studies involving 7,173 participants from both intervention and observational research designs. Effect sizes were separately meta-analyzed for two-group comparison studies (SMD=.20), pre-post contrast studies (ESsg=.62), and associational studies (r=-.06), in the fixed-effect model. <br><br>RESULTS from the random-effects model also suggest a range of effects of omega-3 fatty acids on reducing aggression (SMD=.24; ESsg=.82; r=-.09). Patterns in the relationship between omega-3s and aggression were additionally observed. Moderator analyses indicated that the effect of omega-3s on aggression is conditioned by how aggressive behaviors are measured, such as through self-report or parent/teacher surveys.<br><br>Copyright © 2016 Elsevier Ltd.
