BACKGROUND
The decoration of interior spaces can lead to dangerous levels of indoor formaldehyde pollution. Exposure to indoor air pollution may be responsible for nearly 2 million deaths per year in developing countries.
OBJECTIVES
To assess the prevalence of indoor formaldehyde pollution caused by decoration and resultant respiratory system symptoms exhibited in exposed adults and children, due to indoor formaldehyde pollution caused by decoration.
METHODS
Survey sites were chosen and indoor formaldehyde concentrations determined according to the standard of formaldehyde in GB50325-2001. Logistic regression models were used to derive odds ratios (ORs) and 95% confidence intervals (95% CIs) after adjusting for potential confounders for this survey.
RESULTS
Formaldehyde concentration was above the standard in 64% of Shenyang City. Some adults surveyed complained of common respiratory system disorders, including coughing (11.8%), nasal irritation (39.2%), Heterosmia (14.51%), and throat irritation (25.27%); 12% of children suffered from asthma. The analysis identified formaldehyde pollution and ventilation frequency as risk factors for respiratory system disorders in both adults (OR=2.603, [95% CI: 1.770-3.828], OR=1.604, [95% CI: 1.146-2.244], respectively) and children (OR=4.250, [2.064-8.753], OR=1.831, [1.006-3.333], respectively).
CONCLUSION
The prevalence of common respiratory system disorders was related both to formaldehyde pollution and insufficient ventilation after decorating.
背景
室内空间装修会导致室内甲醛污染达到危险水平。在发展中国家，接触室内空气污染每年可能导致近200万人死亡。
目的
评估装修引起的室内甲醛污染的患病率，以及暴露的成人和儿童因装修引起的室内甲醛污染而出现的呼吸系统症状。
方法
根据GB50325-2001中甲醛标准选择调查地点并测定室内甲醛浓度。本调查在调整潜在混杂因素后，使用逻辑回归模型得出比值比（OR）和95%置信区间（95%CI）。
结果
沈阳市64%的甲醛浓度超标。一些接受调查的成年人抱怨有常见的呼吸系统疾病，包括咳嗽（11.8%）、鼻刺激（39.2%）、嗅觉异常（14.51%）和咽喉刺激（25.27%）；12%的儿童患有哮喘。分析确定甲醛污染和通风频率是成人（OR分别为2.603，[95%CI：1.770-3.828]；OR为1.604，[95%CI：1.146-2.244]）和儿童（OR分别为4.250，[2.064-8.753]；OR为1.831，[1.006-3.333]）呼吸系统疾病的危险因素。
结论
常见呼吸系统疾病的患病率与装修后的甲醛污染和通风不足均有关。
