It 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.
We 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.
Regardless 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.
Our 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.
有研究表明,高鱼类摄入量可改善心理健康。本研究旨在评估高鱼类摄入量或 ω-3 多不饱和脂肪酸(PUFA)的摄入是否与减少自我报告的心理困扰有关。
我们使用了三个横断面数据集,即全国健康 2000 调查(n=5840)、芬兰渔民及其家庭成员的渔民研究(n=1282)和芬兰双胞胎 16 岁研究(n=4986)。数据基于自我管理的问卷、访谈、健康检查和血液样本。使用 12 项和 21 项一般健康问卷(GHQ)测量心理困扰。通过食物频率问卷(FFQ,g/天)和独立频率问题(次/月)测量鱼类摄入量。PUFA 的饮食摄入量(g/天)和血清浓度(占脂肪酸的百分比)。使用回归分析分析关系。
无论采用哪种测量方法,在任何数据集中,鱼类摄入量和 ω-3PUFA 的饮食摄入量均与困扰无关。与假设相反,在渔民研究男性中,高血清二十二碳六烯酸与高困扰有关。在血清 ω-3PUFA 或鱼类摄入量(次/月)和困扰之间检测到一些非线性关联。在渔民研究中,这些关联受酒精摄入、吸烟和体力活动的影响。
我们的结果不支持高鱼类摄入量或 ω-3PUFA 摄入与一般人群或高鱼类摄入量人群中心理困扰减少相关的假设。
