ABSTRACT
Objective The present study was conducted to investigate the perception of haze among pregnant women and to provide basis for developing interventions.Methods A pregnant woman who has been living in Shunyi district for at least six months has been selected as the subject of investigation. A self-designed questionnaire was used to conduct field investigation. Results A total of 320 questionnaires were collected, including 308 valid questionnaires and 96.25% effective questionnaires. In terms of the cognitive aspects of haze, pregnant women think that there is a serious harm to the respiratory system, and 52.27%(161/308)of pregnant women think that the haze is harmful to the cardiovascular system. In the area of haze protection, 79.22%(244/308)of pregnant women wear masks when they go out. Pregnant women who are in the haze of 100.00% (308/308)will reduce window ventilation time. Access to information about haze information and protection knowledge is mainly including mobile phones(83.12%), network(44.16%)and TV(23.38%). The multi-factor logistic regression analysis showed that the haze was harmful to the health of the fetus (OR=0.12, 95%CI: 0.031-0.446), which was the influencing factor of the pregnant women's haze protection measures. Conclusion Pregnant women in Shunyi District have higher awareness of haze knowledge, and the influencing fact of the measures on the haze weather is the cognition that the haze is harmful to the health of the fetus.
