抑郁症患者睡眠质量的主客观差异及相关因素

目的:探究抑郁症患者主客观睡眠质量之间的差异以及此差异的相关因素.方法:采用美国精神障碍诊断与统计手册第四版(DSM-Ⅳ)诊断标准,共收录30例以失眠为主诉的抑郁症患者,汉密尔顿抑郁量表17项版本(HAMD-17)总分≥17分.对照组共14例,均排除严重躯体器质性疾病、精神疾病史及家族史.采用匹茨堡睡眠质量指数量表(PSQI)评定主观睡眠质量.采用多导睡眠监测仪(PSG)评定客观睡眠质量.结果:与对照组比较,抑郁症组的主客观睡眠时间、睡眠潜伏期及睡眠效率差异均有统计学意义(P＜ 0.001).抑郁症组的主客观睡眠质量差异与PSQI及HAMD-17分数均存在相关性(P＜0.05).结论:抑郁症患者缺乏主观睡眠满足感,存在夸大主观失眠严重程度的倾向,其主客观睡眠质量存在明显差异,且此差异与HAMD-17睡眠障碍因子分存在相关性,提示抑郁症状在抑郁症患者的主客观睡眠质量差异中起到重要作用.

Differences between objective and subjective sleep quality in depressed patients and the correlative factors

Objective To investigate the differences between objective and subjective sleep quality in depressed patients and the correlative factors.Methods 30 depressed patients complained of insomnia have been diagnosed and assessed by DSM-IV diagnostic criteria for depression.The cases’ HAMD-17 scores were equal to or more than 17.There were 14 normal controls without serious physical diseases,mental diseases and family history of mental diseases.Both cases and controls were estimated with Pittsburgh sleep quality index(PSQ1) for subjective sleep quality and monitored by the whole-night polysomnography(PSG) records for objective sleep quality.Results Compared with the differences in the controls,there were significant differences between the subjective and objective sleep quality in the depressed patients(P < 0.001).The differences between the subjective and objective sleep quality were also related to the scores of PSQI and HAMD-17 in the depressed patients(P< 0.05).Conclusions The depressed patients lacked satisfaction with the subjective sleep quality and they might overstate the severity of insomnia.The differences between the subjective and objective sleep quality in the depressed patients were related to the severity of depression.However,the severity of depression might also influence the differences between the subjective and objective sleep quality in the depressed patients.
