To date, few studies have analyzed the relationships between socioeconomic status (SES) and indoor air quality (IAQ).
The aim of this study was to examine the relationships between socioeconomic and other factors and indoor air pollutant levels in French homes.
The indoor air concentrations of thirty chemical, biological and physical parameters were measured over one week in a sample of 567 dwellings representative of the French housing stock between September 2003 and December 2005. Information on SES (household structure, educational attainment, income, and occupation), building characteristics, and occupants' habits and activities (smoking, cooking, cleaning, etc.) were collected through administered questionnaires. Separate stepwise linear regression models were fitted to log-transformed concentrations on SES and other factors. Logistic regression was performed on fungal contamination data.
Households with lower income were more likely to have higher indoor concentrations of formaldehyde, but lower perchloroethylene indoor concentrations. Formaldehyde indoor concentrations were also associated with newly built buildings. Smoking was associated with increasing acetaldehyde and PM2.5 levels and the risk of a positive fungal contamination index. BTEX levels were also associated with occupant density and having an attached garage. The major predictors for fungal contamination were dampness and absolute humidity.
These results, obtained from a large sample of dwellings, show for the first time in France the relationships between SES factors and indoor air pollutants, and believe they should be considered alongside occupant activities and building characteristics when study IAQ in homes.
迄今为止，很少有研究分析社会经济地位（SES）与室内空气质量（IAQ）之间的关系。
本研究旨在探讨法国住宅中社会经济因素及其他因素与室内空气污染物水平之间的关系。
在2003年9月至2005年12月期间，对567套具有法国住房代表性的住宅进行了为期一周的室内空气30种化学、生物和物理参数浓度的测量。通过问卷调查收集了有关社会经济地位（家庭结构、教育程度、收入和职业）、建筑特征以及居住者的习惯和活动（吸烟、烹饪、清洁等）的信息。对社会经济地位及其他因素的对数转换浓度分别拟合逐步线性回归模型。对真菌污染数据进行逻辑回归分析。
低收入家庭更有可能室内甲醛浓度较高，但室内全氯乙烯浓度较低。室内甲醛浓度还与新建建筑有关。吸烟与乙醛和PM2.5水平升高以及真菌污染指数呈阳性的风险有关。苯系物水平也与居住者密度和有附属车库有关。真菌污染的主要预测因素是潮湿和绝对湿度。
这些来自大量住宅样本的结果首次在法国表明了社会经济地位因素与室内空气污染物之间的关系，并认为在研究家庭室内空气质量时，应将这些关系与居住者活动和建筑特征一并考虑。
