The effect of omega-3 long chain polyunsaturated fatty acids on aggressive behaviour in adult male prisoners: a structured study protocol for a multi-centre, double-blind, randomised placebo-controlled trial and translation into policy and practice

The study focuses on the potential of nutritional interventions, particularly omega-3 fatty acids (n-3 LCPUFA), to manage aggression and reduce recidivism among prisoners. Recognizing the gap in research regarding the impact of diet on prisoner behavior, this trial aims to explore how omega-3 supplements might influence aggressive actions. The experiment will involve 600 male prisoners with histories of aggression from at least six correctional facilities, who will be randomly assigned to receive either n-3 LCPUFA supplements or a placebo for 16 weeks. The primary tool for measuring the intervention’s effectiveness will be the Inmate Behavioural Observation Scale (IBOS), alongside other assessments focused on aggression, mental health, and recidivism. The goal is to provide solid evidence on whether omega-3 intake can positively affect prisoner behavior and mental health, potentially guiding future nutritional policies in prisons and contributing to preventive mental health strategies in the wider community.
