The purpose of the present study was to investigate the relation state and trait anxiety and adipose tissue essential fatty acid precursors for prostaglandins E1 and E2.
The sample consisted of 144 male and female Cretan adults, 23 to 69 years of age. Anthropometric and arterial blood pressure measurements were taken, and adipose tissue samples as well as data concerning general health habits were collected. Dietary data were collected using the weekly food frequency questionnaire and the 24-hour dietary recall method, while state and trait anxiety was assessed through the use of the Spielberger State-Trait Anxiety Inventory (STAI) and the Zung anxiety scale.
State anxiety (STAI) related positively with sex (p < 0.0003) and negatively with adipose fat myristic acid (C14:0) (p < 0.004). Similarly, Zung trait anxiety related positively with sex (p < 0.0001) and negatively with adipose tissue myristic acid (C14:0) (p < 0.04). Spielberger trait anxiety related positively with adipose (LA + ALA)/(AA + EPA) ratio (p < 0.0002) and negatively with (C14:0) (p < 0.02) and dietary monounsaturated fat (p < 0.03).
It appears that the positive relation between trait anxiety and adipose (LA + ALA)/(AA + EPA) ratio may stem from the inhibiting role of catecholamines on delta 6 and delta 5 desaturases.
本研究旨在调查状态焦虑和特质焦虑与前列腺素E1和E2的脂肪组织必需脂肪酸前体之间的关系。
样本包括144名23至69岁的克里特岛成年男女。进行了人体测量和动脉血压测量，并收集了脂肪组织样本以及有关一般健康习惯的数据。使用每周食物频率问卷和24小时饮食回忆法收集饮食数据，同时通过使用斯皮尔伯格状态-特质焦虑量表（STAI）和zung焦虑量表评估状态焦虑和特质焦虑。
状态焦虑（STAI）与性别呈正相关（p < 0.0003），与脂肪组织肉豆蔻酸（C14:0）呈负相关（p < 0.004）。同样，zung特质焦虑与性别呈正相关（p < 0.0001），与脂肪组织肉豆蔻酸（C14:0）呈负相关（p < 0.04）。斯皮尔伯格特质焦虑与脂肪（LA + ALA）/（AA + EPA）比值呈正相关（p < 0.0002），与（C14:0）呈负相关（p < 0.02）和饮食单不饱和脂肪呈负相关（p < 0.03）。
特质焦虑与脂肪（LA + ALA）/（AA + EPA）比值之间的正相关似乎可能源于儿茶酚胺对δ6和δ5去饱和酶的抑制作用。
