研究表明，大量食用鱼类可以改善心理健康。这项研究的目的是评估大量食用鱼类或摄入omega-3多不饱和脂肪酸（PUFA）是否与减少自我报告的心理困扰有关。方法我们使用了三个横断面数据集，即全国健康调查2000 (n= 5840)，渔民研究芬兰渔民及其家庭成员（n= 1282）和Finntwin16研究年轻人（n= 4986）。数据基于自我填写的问卷、访谈、健康检查和血液样本。采用12项和21项一般健康问卷（GHQs）测量心理困扰。通过食物频率问卷（FFQ, g/day）和独立频率问题（次/月）测量鱼类消费量。测定PUFAs的日摄入量（g/d）和血清浓度（来自脂肪酸的百分比）。采用回归分析分析相关关系。结果无论采用何种测量方法，在任何数据集中，鱼的摄入量和omega-3 PUFA的摄入量都与痛苦无关。与假设相反，高血清二十二碳六烯酸与渔夫研究中男性的高痛苦有关。血清omega-3 PUFAs或鱼类消费（次/月）与焦虑之间存在一些非线性关联。在渔民研究中，饮酒、吸烟和体育活动改变了这种关联。结论：我们的研究结果不支持鱼类消费或omega-3 PUFA摄入与一般人群或高鱼类消费人群的心理困扰减少有关的假设。
BackgroundIt has been suggested that high fish consumption improves mental well-being. The aim of this study was to assess whether high fish consumption or omega-3 polyunsaturated fatty acid (PUFA) intake was associated with reduced self-reported psychological distress.MethodsWe used three cross-sectional data sets, the nationwide Health 2000 Survey (n= 5840), the Fishermen Study on Finnish fishermen and their family members (n= 1282) and the Finntwin16 Study on young adults (n= 4986). Data were based on self-administered questionnaires, interviews, health examinations and blood samples. Psychological distress was measured using the 12-item and 21-item General Health Questionnaires (GHQs). Fish consumption was measured by a food frequency questionnaire (FFQ, g/day) and independent frequency questions (times/month). Dietary intake (g/day) and serum concentrations (% from fatty acids) of PUFAs were determined. Relationships were analysed using regression analysis.ResultsRegardless of the measure, fish consumption and omega-3 PUFA dietary intake were not associated with distress in any of the data sets. In contrast to the hypothesis, high serum docosahexaenoic acid was associated with high distress in the Fisherman Study men. Some non-linear associations were detected between serum omega-3 PUFAs or fish consumption (times/month) and distress. In the Fishermen Study, the associations were modified by alcohol consumption, smoking and physical activity.ConclusionsOur results do not support the hypothesis that fish consumption or omega-3 PUFA intake are associated with reduced psychological distress in the general population or in a population with high fish consumption.
