Second hand smoke exposure in pregnant women in Dehradun, Uttarakhand: A cross sectional study.

Aim: The aim of this study was to estimate the percentage and sources of secondhand smoke (SHS) exposure among non-smoking pregnant women. It was a cross-sectional study conducted among the non-smoking pregnant women registered at the primary health center (PHC) under the All India Institute of Medical Science (AIIMS), Rishikesh. Materials and Methods: All registered pregnant women at sub-center in the field practice area (Raiwala) of the Department of Community and Family Medicine, AIIMS Rishikesh were recruited in the study. In this study, a questionnaire was used for measuring the exposure of SHS. Mean and standard deviation (SD), median, minimum, and maximum were used for continuous variables. A Chi-square test was used to compare the association of categorical variables. Results: Out of the total participants, 62% were exposed to SHS. 33% of participants were exposed to SHS at home only, 24% at public places only, and 5% were the ones exposed both at home and public places. More than half (69%) of the participants were having inadequate knowledge about the harms caused by SHS. Conclusions: More than half of the participants were exposed to SHS. Inadequate knowledge among the participants about adverse effects of SHS exposure and insufficient practices and action were observed. [ABSTRACT FROM AUTHOR]
