Effect of vitamin A on aggressive behavior in youth. 2022 ASC Annual Meeting, Atlanta, GA.http://hdl.handle.net/20.500.11861/8594https://convention2.allacademic.com/one/asc/asc22/index.php?cmd=Online+Program+View+Paper&selected_paper_id=1966157&PHPSESSID=dju4auhg9ke9a4qb4m6elif4iaBackground: Previous literature found that nutritional diet such as vitamin A is effective in enhancing neuropsychological functions. The present study aimed to investigate the effect of vitamin A dietary on reducing aggressive behaviors in youth.<br> Method: One hundred youth, between 12 and 24 years of age (mean age= 18.41 years; 65 females and 35 males), completed a dietary, behavioral and neurocognitive- related questionnaire. All participants were asked to fill out the neuropsychological measures and the Reactive- Proactive Aggression Questionnaire. A three days (2 weekdays and 1 weekend) dietary report of each participant was recorded and the average of the 3-day dietary intake was computed for data analyses in the present study.<br> Result: Regression analysis was performed. After controlling for age, gender, family income and neuropsychological scores, vitamin A intake still significantly predicted reactive aggression in youth (b= -0.002, p= 0.001) while it was not significant for proactive aggression.<br> Conclusion: These pilot findings suggest that vitamin A dietary has a beneficial effect on reducing reactive aggression and such effect is still present after controlling for neuropsychological functions in youth. These have important clinical implications. Specifically, higher intake of vitamin A should be encouraged in youths so to reduce their aggressive behaviors.enConference Paper
