背景:精神病症状(PS)经常出现在患有焦虑抑郁症(AD)的年轻人中,然而,抑郁和PS之间的关系的中介仍不清楚.这项研究旨在调查PS在首发和药物初治(FEDN)青年AD中的患病率和危险因素,并试图阐明促甲状腺激素(TSH)水平之间的关系。焦虑,抑郁症,PS,以及确定潜在的中介角色。
方法:招募369名FEDN青年AD患者。使用阳性和阴性综合征量表的阳性子量表评估临床症状,汉密尔顿抑郁量表(HAMD),和汉密尔顿焦虑量表(HAMA)。空腹血糖,脂质,甲状腺功能也被收集。
结果:青年AD患者PS的患病率(21.68%)是非AD患者的12.24倍。HAMD评分(P=0.005,OR=1.23),HAMA评分(P<0.001,OR=1.62),TSH水平(P=0.025,OR=1.20)是PS的显著预测因子。区分有和没有PS的年轻成年人的曲线下面积值为0.86。我们还确定了TSH水平和焦虑对抑郁与PS关联的一系列多重中介作用。
结论:这些发现强调了焦虑和TSH水平作为抑郁和PS之间关联的系列介质的作用。因此,在治疗患有AD的年轻人的PS时,重要的是不仅要关注抑郁症,而且对TSH水平和焦虑有最大的好处。
BACKGROUND: Psychotic symptoms (PS) frequently occur in young adults with anxious depression (AD), yet the mediators of the associations between depression and PS remain unclear. This study aimed to investigate the prevalence and risk factors of PS in first-episode and drug-naïve (FEDN) young adults with AD and attempted to elucidate the relationship between thyroid-stimulating hormone (TSH) levels, anxiety, depression, and PS, as well as to identify potential mediating roles.
METHODS: 369 FEDN young adults with AD were recruited. Clinical symptoms were assessed using the Positive and Negative Syndrome Scale\'s positive subscale, the Hamilton Depression Rating Scale (HAMD), and the Hamilton Anxiety Rating Scale (HAMA). Fasting glucose, lipids, and thyroid function were also collected.
RESULTS: The prevalence of PS in young adults with AD (21.68 %) was 12.24 times higher than in non-AD patients. The HAMD scores (P = 0.005, OR = 1.23), HAMA scores (P < 0.001, OR = 1.62), and TSH levels (P = 0.025, OR = 1.20) were significant predictors of PS. The combined area under the curve value for distinguishing young adults with AD with and without PS was 0.86. We also identified serial multiple mediating effects of TSH levels and anxiety on the association of depression with PS.
CONCLUSIONS: These findings emphasize the role of anxiety and TSH levels as serial mediators of the association between depression and PS. Therefore, when treating PS in young adults with AD, it is important to focus not only on depression, but also on TSH levels and anxiety to maximize benefit.
