A depressive state and feelings of unhappiness in daily life are regarded as indispensable factors for the diagnosis of major depression. These factors are also speculated to contribute to subsequent psychological wellbeing.
A total of 3190 men, aged 33 to 59 years, from a workplace in Japan participated in this one-year prospective study conducted from 2007 to 2008; 3141 men completed both evaluations (98.5%). The prevalences of depressive states and feelings of unhappiness were evaluated using a questionnaire. After one year, psychological wellbeing was evaluated using the General Health Questionnaire (GHQ) 12-item version. Analysis of variance and a logistic regression analysis were used for the analysis.
The prevalence of no depressive feelings and no feelings of unhappiness among the workers were 73.5% among men in their 30s, 76.9% among men in their 40s, and 83.2% among men in their 50s. The mean GHQ score among participants with or without of depressive feelings and feelings of unhappiness was significantly higher than that among participants who had no depressive feelings and no feelings of unhappiness (control group). In contrast, the mean GHQ score among the participants in their 50s who had only depressive feelings did not differ from that in the control group of participants in their 50s according to a multivariate analysis.
Compared with depressive feelings, feelings of unhappiness were a stronger contributing factor to psychological wellbeing as measured using the GHQ questionnaire, especially among subjects in their 50s, in a one-year follow-up study.
抑郁状态和日常生活中的不幸福感被视为重度抑郁症诊断的必要因素。这些因素也被推测会对随后的心理健康产生影响。
共有3190名年龄在33至59岁之间的日本男性，来自日本的一个工作场所，参与了这项于2007年至2008年进行的为期一年的前瞻性研究；3141名男性完成了两项评估（98.5%）。使用问卷评估抑郁状态和不幸福感的患病率。一年后，使用一般健康问卷（GHQ）12项版本评估心理健康。采用方差分析和逻辑回归分析进行分析。
在30多岁的男性中，无抑郁情绪和无不幸福感的患病率为73.5%，40多岁的男性中为76.9%，50多岁的男性中为83.2%。有或无抑郁情绪和不幸福感的参与者的平均GHQ得分显著高于无抑郁情绪和无不幸福感的参与者（对照组）。相比之下，根据多变量分析，50多岁仅患有抑郁情绪的参与者的平均GHQ得分与50多岁对照组参与者的得分没有差异。
在一项为期一年的随访研究中，与抑郁情绪相比，使用GHQ问卷测量时，不幸福感对心理健康的影响更大，尤其是在50多岁的受试者中。
