Aims:An increase in psychosomatic symptoms among adolescents has recently been reported. Few studies have examined the relation between food intake and psychosomatic symptoms. The aim was to study the association between food intake and overall psychosomatic burden and separate psychosomatic symptoms.Methods:In this cross-sectional study, we used data from 6248 girls and 7153 boys in south-east Sweden who turned 16 years of age during the academic years 2009/2010 to 2015/2016 and responded to a health questionnaire at the school health services. The association between overall healthy food intake and a low psychosomatic burden was calculated as odds ratios (95% confidence interval) and stratified for other lifestyle habits and gender.Results:Sixty-nine per cent of the boys and 35% of the girls had a low psychosomatic burden. There was a positive association between an overall healthy food intake and a low psychosomatic burden ( P<0.0001), regardless of other lifestyle habits and gender. An overall healthy food intake was also positively associated with a lower frequency of the separate psychosomatic symptoms of concentration difficulties, sleep difficulties, a poor appetite or dizziness ( P<0.0001).Conclusions:A healthy food intake seems to be associated with a low psychosomatic burden among adolescents. Further knowledge is needed to explore whether an improved food intake can reduce psychosomatic symptoms and enhance mental health.

16 岁青少年食物摄入量与心身症状之间的关联

目的：最近有报道称青少年心身症状有所增加。很少有研究探讨食物摄入量与心身症状之间的关系。目的是研究食物摄入量与整体心身负担和单独的心身症状之间的关系。方法：在这项横断面研究中，我们使用了瑞典东南部 6248 名女孩和 7153 名男孩的数据，他们在2009/2010 学年至 2015/2016 学年，并在学校卫生服务处填写了健康调查问卷。总体健康食物摄入量与低心身负担之间的关联以比值比（95% 置信区间）计算，并针对其他生活习惯和性别进行分层。 结果：69% 的男孩和 35% 的女孩有心身负担低。无论其他生活习惯和性别如何，总体健康食物摄入量与低心身负担之间存在正相关（P<0.0001）。总体健康食物摄入量也与注意力不集中、睡眠困难、食欲不振或头晕等单独心身症状的较低频率呈正相关（P<0.0001）。结论：健康食物摄入量似乎与较低的心身症状相关。青少年的负担。需要进一步的知识来探索改善食物摄入是否可以减少心身症状并增强心理健康。
