Abstract:
Objectives To study the impact of indoor decoration pollution on abnormal pregnancy.
Methods To conduct multi-conditional logistic regression analysis based on the interview results of 200 abnormal pregnancy cases and the matched controls (age±2 years).
Results The proportion of decoration using materials with volatile odor at home or work units during pregnancy or within six months before pregnancy in the case group (32.0%) is significantly higher than the control group (20.5%, χ2=6.81, P=0.009). The time with decoration odor in case group (P50=3 months) was significantly higher than that in the control group (P50=1 month, H=6.67, P=0.010).Taking houses without decoration odor as control, the relative risks of the time with decoration odor ≤3 and > 3 months are 1.25 and 5.41 (trend χ2=10.86, P=0.001) respectively. After adjusting the impact of other risk factors by multifactor analysis, the time with decoration odor over 3 months may significantly increase the occurrence of abnormal pregnancy (OR=13.36, 95%CI:1.27~140.19).
Conclusion Indoor decoration pollution may be one of the risk factors for abnormal pregnancy, and a dose-response relationship may exist between them.
