“…Physical comorbidities were positively associated with secondhand smoking, a nding that echoes previous research linking secondhand smoking during pregnancy to various negative health outcomes, such as preterm delivery, fetal growth restriction, spontaneous abortion, birth defects, and fetal death [1,2]. Secondhand smoking can also increase risk for atherosclerosis and cardiovascular diseases, lung cancers, oral and esophageal cancers, and bone marrow myeloid leukemia [9].…”

“…For instance, a cross-sectional study in Greece showed that 36% of women reported active smoking, but 94% of these women were exposed to passive smoking during pregnancy [7]. A similar study in Taiwan found that 7.2% of pregnant women smoked during pregnancy, and 40.6% of these women were exposed to secondhand smoking [1]. A study in southern China found that 2.63% of pregnant women had a history of smoking; of these, 52.15% were also exposed to secondhand smoke during their pregnancy [8].…”

“…Both active smoking and exposure to secondhand smoking during pregnancy are well-known risk factors for compromised health and poor future health of infants. Studies have found that active smoking in pregnancy is associated with increased risk for low birth weight, small chest circumference, and sudden infant death syndrome, while exposure to secondhand smoking is associated with preterm delivery, fetal growth restriction, spontaneous abortion, and fetal death [1,2].…”

BackgroundInhalation of secondhand smoke during pregnancy and postnatal period is detrimental to developing infants and increases risk for health problems throughout the lifespan. This study examined the prevalence of exposure to secondhand smoke, its correlates, and its association with QOL among pregnant and postnatal Chinese women.MethodsThis multicenter, cross-sectional study was conducted between February and October 2019 in China. Participants were pregnant and postnatal women. We assessed associations of frequency and location of secondhand smoking with sample characteristics as well as depression and quality of life based on EPDS and WHOQOL-BREF, respectively.ResultsA total of 992 women participated in the study, of whom, 211 (21.3%, 95%CI=18.7-23.8%) had been exposed to secondhand smoking. Secondhand smoking was most common in public areas (56.4%), and residential homes (20.5%), while workplaces had the lowest rate of secondhand smoking (13.7%). Women with physical comorbidities were more likely to report secondhand smoking exposure, while younger women, women living in urban areas, and those with college or higher education level were less likely to report exposure to secondhand smoking.ConclusionThe prevalence of exposure to secondhand smoking is becoming lower among pregnant and postnatal women in China compared to findings reported in previous studies. Due to the detrimental impact of secondhand smoking on physical health, legal legislation should be promptly enforced to establish smoke-free environments in both public and private urban/rural areas for protection of pregnant and postnatal women, especially those who are physically vulnerable and less educated.

“…The prevention of smoking and exposure to smoking during pregnancy is an important global issue and requires further research. Maternal smoking was associated with LBW in our study, which concurs with the findings of many previous studies about the adverse effects of smoking exposure on pregnancy outcomes (56)(57)(58).…”

Background: Low birth weight (< 2.5 kg) is an important indicator of health and development of infants throughout their life. Aims: This study aimed to determine the prevalence and risk factors for low birth weight in Jordan and its association with under-5 mortality. Methods: In this secondary analysis, data were extracted from the 2012 Jordan Population and Family Health Survey for 9734 live births born in the 5 years preceding the survey and for which birth weight was reported. Data were collected on child and maternal characteristics. Multivariable regression analysis was used to determine the significant risk factors for low birth weight and mortality. Results: Of the 9734 births analysed, 13.8% were low birth weight and 1.3% were very low birth weight. Mother's age (< 30 and ≥ 35 years), education (less than higher education), birth interval (< 24 months and first birth), unplanned pregnancy, household wealth status (poorest and richest), consanguinity, residence (central and south regions of Jordan), female sex, birth order (1 and ≥ 6), twin birth and maternal smoking during pregnancy were significant risk factors for low birth weight. The risk of death under 5 years of age was 4.8 times higher in children with low birth weight than children with normal birth weight. Conclusions: The high rate of low birth weight and its increasing rate in Jordan is a challenge for public health. Preventing low birth weight neonates and increasing their survival need to be prioritized in the national health strategy. Special care needs to be taken for the high-risk groups identified in this study.

“…Pregnancy is an ideal opportunity to intervene with mothers and families to prevent and control tobacco use, and should be a priority for both tobacco control and maternal and child health care [22]. Our results are consistent with earlier studies on tobacco smoke exposure [19,23,24]. The fraction of active smokers (1.4%) was too low in our study to allow a specific analysis, but other studies demonstrate that active smoking is related to the same endpoints and only the impact seems to be more pronounced [25,26].…”

Background: It is known that environmental tobacco smoke (ETS) has adverse effects on pregnancy and birth outcomes. We aimed to assess the impact of ETS in pregnant women with and without asthma. Methods: A cohort study was conducted from August 2014 to June 2015 enrolling 1603 pregnant women during their 2nd trimester. Data on tobacco exposure were collected at first visit and women were followed through pregnancy till postpartum. Results: Of the 1603 women, 231 reported passive smoking, 223 non-asthmatics and 8 asthmatics. Women exposed to ETS during pregnancy were more likely to have an infant admitted to the pediatric ward (10.8% vs. 6.5%, p = 0.026) and to have low one-and five-minute Apgar scores (1 min: 6.1% vs. 2.6%, p = 0.011; 5 min: 2.2% vs. 0.7%, p = 0.039). Complications of pregnancy were also elevated in women exposed to ETS (53.7% vs. 42.3%, p = 0.002). Asthma had no additional effect beyond the impact of ETS except for cesarean sections that were more frequent in women with asthma exposed to ETS. Conclusions: Due to the small number of women with asthma exposed to ETS, combined effects of asthma and ETS were only found for cesarean sections. Still counseling of pregnant women about adverse effects of ETS should consider women's asthma as an additional reason to avoid ETS.
