BACKGROUND
There is emerging evidence that the supplementation of omega-3 contributes to a decrease in aggressive behaviour in prison populations. A challenge of such research is achieving statistical power against effect sizes which may be affected by the baseline omega-3 index. There are no published data on the blood omega-3 index with studies of this kind to assess the variability of the blood omega-3 index in conjunction with aggression and attention deficit assessments.
OBJECTIVE
To determine if the variance of the omega-3 index is correlated with aggressive and attention deficit behaviour in a prison population.
DESIGN
136 adult male prisoners were recruited from South Coast Correctional Centre (SCCC), NSW Australia. A 7 point categorisation was used to quantify levels of aggressive behaviour (4 weeks) from individual SCCC case notes, whereby higher scores correspond to increasingly aggressive behaviour. Study participants completed the Aggression Questionnaire (AQ) and the Brown's Attention Deficit Disorder Scales (BADDS), provided a blood sample for erythrocyte fatty acid analysis using gas chromatography and the omega-3 index was calculated.
RESULTS
The baseline omega-3 index ranged from 2.3% to 10.3%, indicating that some participants already had substantial omega-3 intake, however a median of 4.7% indicated a lower overall omega-3 intake than the general Australian population. Assessment of aggressive and attention deficit behaviour shows that there were negative correlations between baseline omega-3 index and baseline aggression categorisation scores (r = -0.21, P = 0.016); total AQ score (r = -0.234, P = 0.011); Anger (r = -0.222 p = 0.016); Hostility AQ (r = -0.239, P = 0.009); indirect aggression (r = -0.188 p = 0.042); total BADDS (r = -0.263, p = 0.005); Activation (r = -0.224, p = 0.016); Attention (r = -0.192, p = 0.043); Effort (r = -0.253, p = 0.007); Affect (r = -0.330, p = 0.000) and Memory (r = -0.240, p = 0.010).
CONCLUSIONS
There is a high variability in omega-3 status of a NSW prison population, and inmates with lower omega-3 index were more aggressive and had higher ADD scores.
背景
越来越多的证据表明，补充ω-3有助于减少监狱人群中的攻击性行为。此类研究面临的一个挑战是，要针对可能受基线ω-3指数影响的效应大小获得统计功效。目前尚无已发表的数据，在这类研究中对血液ω-3指数进行评估，以结合攻击行为和注意力缺陷评估来评估血液ω-3指数的变异性。
目的
确定ω-3指数的方差是否与监狱人群中的攻击行为和注意力缺陷行为相关。
设计
从澳大利亚新南威尔士州南海岸惩教中心（SCCC）招募了136名成年男性囚犯。使用7分分类法从SCCC的个人病例记录中量化攻击行为水平（4周），分数越高表明攻击行为越严重。研究参与者完成了攻击问卷（AQ）和布朗注意力缺陷障碍量表（BADDS），提供血样用于气相色谱法进行红细胞脂肪酸分析，并计算ω-3指数。
结果
基线ω-3指数范围为2.3%至10.3%，这表明一些参与者已经摄入了大量的ω-3，然而中位数为4.7%，表明总体ω-3摄入量低于澳大利亚普通人群。对攻击行为和注意力缺陷行为的评估表明，基线ω-3指数与基线攻击分类分数之间存在负相关（r = -0.21，P = 0.016）；AQ总分（r = -0.234，P = 0.011）；愤怒（r = -0.222，p = 0.016）；敌意AQ（r = -0.239，P = 0.009）；间接攻击（r = -0.188，p = 0.042）；BADDS总分（r = -0.263，p = 0.005）；激活（r = -0.224，p = 0.016）；注意力（r = -0.192，p = 0.043）；努力（r = -0.253，p = 0.007）；情感（r = -0.330，p = 0.000）和记忆（r = -0.240，p = 0.010）。
结论
新南威尔士州监狱人群的ω-3状态存在很大变异性，ω-3指数较低的囚犯攻击性更强，ADD分数更高。
