There is paucity of studies on prevalence of SHS among pregnant women and its association with low birth weight (LBW).
The study was designed to determine the proportion of tobacco use, exposure to second hand smoke among pregnant women and their association with LBW.
A Retrospective cohort study was conducted from March-June 2017 among 1043 pregnant women admitted for delivery in the Department of Obstetrics and Gynecology, JIPMER. Socio-demographic and obstetric characteristics, tobacco use and exposure to SHS during pregnancy were assessed by interviews. Birth weight of the baby was also extracted. Data was analysed using STATA v12. Univariate analysis was used to assess the association of socio-demographic, obstetric characteristics and exposure to SHS with LBW.
Out of 1043 pregnant women, the mean age was 25 (±3.9) years. More than half (57.4%) of women were primigravida. The proportion of women exposed to SHS during pregnancy was 69.9% (95% CI: 67.0-72.6) among which 24% of the women belonged to family, where family members were smokers. Only four had ever used tobacco in the past. However, none used any form of tobacco during pregnancy. LBW was present in 21.4% of the babies. There was no association between exposure to SHS and LBW [PR:0.98 (95% CI:0.71-1.35)].
The study shows that there was no significant association between the SHS exposure of pregnant women and low birth weight.
关于孕妇中无烟烟草使用情况及其与低出生体重（LBW）关联的研究较少。
本研究旨在确定孕妇中烟草使用、二手烟暴露的比例及其与低出生体重的关联。
2017年3月至6月，在JIPMER妇产科收治的1043名分娩孕妇中进行了一项回顾性队列研究。通过访谈评估社会人口统计学和产科特征、孕期烟草使用和二手烟暴露情况。还提取了婴儿的出生体重。使用STATA v12进行数据分析。单因素分析用于评估社会人口统计学、产科特征和二手烟暴露与低出生体重的关联。
1043名孕妇的平均年龄为25（±3.9）岁。超过一半（57.4%）的女性为初产妇。孕期暴露于二手烟的女性比例为69.9%（95%CI：67.0 - 72.6），其中24%的女性家庭成员中有吸烟者。过去仅有4人使用过烟草。然而，孕期无人使用任何形式的烟草。21.4%的婴儿为低出生体重。二手烟暴露与低出生体重之间无关联[PR：0.98（95%CI：0.71 - 1.35）]。
该研究表明孕妇二手烟暴露与低出生体重之间无显著关联。
