The negative impact of depressive symptoms on quality of life has been the focus of increasing attention, yet this relation remains unstudied in samples from developing countries. The objective of this study was to determine whether the occurrence of depressive symptoms is associated with impaired quality of life and whether this association remains significant after adjustment for some variables.
A convenience sample was selected and the measures used were the WHOQOL-100, to assess quality of life, the Beck Depression Inventory, to screen for depressive symptoms, and the Economic Classification Criterion - Brazil, to evaluate socioeconomic status.
One hundred nineteen healthy adults (community) and 122 adult patients (tertiary hospital) from Brazil were assessed. Depressive symptoms were negatively correlated with all the domains of quality of life, even after statistical control for age, socioeconomic status, and presence of chronic health conditions. Socioeconomic status was positively correlated with the social relationships and environmental domains of quality of life.
Our findings indicate that depressive symptoms and socioeconomic status are important elements affecting the relationship between chronic health conditions and quality of life in Brazil.
抑郁症状对生活质量的负面影响已引起越来越多的关注，但在发展中国家的样本中，这一关系仍未得到研究。本研究旨在确定抑郁症状的发生是否与生活质量受损有关，以及在调整一些变量后，这种关联是否仍然显著。
采用方便抽样法，使用的测量工具包括 WHOQOL-100，用于评估生活质量；贝克抑郁量表，用于筛查抑郁症状；以及巴西经济分类标准，用于评估社会经济状况。
对来自巴西的 119 名健康成年人（社区）和 122 名成年患者（三级医院）进行了评估。抑郁症状与生活质量的所有领域都呈负相关，即使在统计上控制了年龄、社会经济地位和慢性健康状况的存在。社会经济地位与生活质量的社会关系和环境领域呈正相关。
我们的研究结果表明，抑郁症状和社会经济地位是影响巴西慢性健康状况与生活质量之间关系的重要因素。
