To examine depression severity and associated risk factors 1 year later among survivors of the May 12, 2008 Wenchuan earthquake in China, a cross-sectional study was conducted. Subjects included 704 survivors, ages 18-64, 367 (52.1 %) of whom were from heavily damaged counties and the rest from moderately damaged ones. Subjects were interviewed for socio-demographic variables, exposure level, and administered standardized scales for depression, anxiety, resilience, and social support. 23.0 % (N = 162) and 13.8 % (N = 97) of all subjects had moderate and severe depression, respectively, with depression severity being higher in severely damaged counties compared to moderately damaged ones (18.2 vs 8.9 %). Multiple regression analysis indicated that depression severity varied with gender, age, education level, exposure level, income, housing status, and social support. The association between income level and symptoms of depression were partially mediated by social support (ratio of mediation effects: 41.9 and 22.3 % for heavily and moderately damaged counties, respectively). The data support the need for early mental health intervention and provision of social support in this vulnerable population.
为了研究中国汶川 5·12 地震 1 年后幸存者的抑郁严重程度和相关风险因素，开展了一项横断面研究。研究对象包括 704 名 18-64 岁的幸存者，其中 367 人（52.1%）来自重灾区，其余人来自中度受灾地区。对研究对象进行了社会人口统计学变量、暴露水平的访谈，并对抑郁、焦虑、适应力和社会支持进行了标准化量表评估。23.0%（N=162）和 13.8%（N=97）的所有研究对象分别有中度和重度抑郁，重灾区的抑郁严重程度明显高于中度受灾地区（18.2%对 8.9%）。多变量回归分析表明，抑郁严重程度与性别、年龄、教育程度、暴露水平、收入、住房状况和社会支持有关。社会支持部分中介了收入水平与抑郁症状之间的关系（重灾区和中度受灾地区的中介效应比例分别为 41.9%和 22.3%）。这些数据支持在这个弱势群体中需要早期心理健康干预和提供社会支持。
