Depression is the leading cause of disability and is projected to become the second highest burden of disease (measured in disability-adjusted life years) by 2020, but only a few studies have examined changes over time in the occurrence of depression. The aim of this study is to provide evidence to the hypothesis that the prevalence of depression is rising in the Danish population. We will do that in a longitudinal design among adult Danes by studying the trends from 2000 to 2006 of major depressive disorder (MDD) as well as the distribution across the whole Major Depression Inventory (MDI) scale. In addition, we will investigate whether the trend in MDD is similar across socioeconomic groups.
A random sample of 4759 Danes in their forties and fifties were followed in a longitudinal study based on postal questionnaires answered in 2000 and 2006.
The prevalence of MDD increased from 2.0% to 4.9% during 2000-06. Also the distribution of the MDI score in its entirety moves higher up the scale, with the 90th percentile changing from 12 in year 2000 to 20 in 2006. The increasing prevalence is in absolute terms more pronounced among women in their forties and in lower socioeconomic positions.
The rising MDI score indicates that MDD as well as mental health generally is of public health concern.
抑郁症是导致残疾的主要原因，预计到 2020 年将成为疾病负担排名第二的疾病（以残疾调整生命年来衡量），但只有少数研究探讨了抑郁症发病率随时间的变化。本研究旨在为抑郁症在丹麦人群中患病率上升的假设提供证据。我们将通过研究 2000 年至 2006 年期间重度抑郁症（MDD）的趋势以及整个 Major Depression Inventory（MDI）量表的分布情况，在丹麦成年人的纵向设计中做到这一点。此外，我们将调查 MDD 趋势是否在社会经济群体中相似。
一项基于问卷调查的纵向研究对 4759 名丹麦中年人进行了随机抽样，这些问卷于 2000 年和 2006 年进行了邮寄回复。
2000-06 年间，MDD 的患病率从 2.0%上升到 4.9%。MDI 评分的分布也向上移动，第 90 百分位从 2000 年的 12 分上升到 2006 年的 20 分。绝对而言，40 多岁的女性和社会经济地位较低的人群中，患病率的上升更为明显。
MDI 评分的上升表明，MDD 以及心理健康总体上是公共卫生关注的问题。
