Background: Maternal smoking is known to pose risks to both baby and mother affecting aspects from fertility and pregnancy outcome to fetal and child development. Objective: To study the prevalence of maternal smoking globally and its adverse pregnancy outcomes. Materials and methods: Health sciences electronic databases PubMed and Google Scholar were searched for studies published between 2006 to March 2020. Keywords used for the search were (“tobacco”), ("maternal smoking"), ("effects of maternal smoking") and (“globally”). A total of 29 articles were included in the review based on the eligibility criteria. Statistical software SPSS-V.23 was used for the statistical application. Result: A total of 29 studies met the inclusion criteria with a total of 11,34,769 women, age ranged from 12-45 years and above. Maternal smoking was reported by 22.26% women. Those women who reside in rural areas, illiterate, homemaker, from low economic status and whose husband smoke have higher maternal smoking prevalence and its adverse pregnancy outcomes were reported as 23.27% low maternal weight, 62.46% anaemic mother, 8.76% low birth weight, 12.86% preterm birth, 79% low birth length and 15.77% obesity among children. Conclusion: Maternal tobacco use in any form increases risk of ill effects on mother and child health. Tobacco cessation during pregnancy is necessary to reduce morbidity and mortality related to tobacco use. Key words: Maternal smoking, cigarette, smokeless tobacco, prevalence, effects of maternal smoking, Globally.

Abstract Background: The health of women during the preconception phase though critical, is a comparatively ignored part in her life cycle. The presence of health risks is judged as hazardous to the wellbeing of women and their forthcoming progeny. The study aimed to estimate the prevalence of various pregnancy outcomes and assess the association between various risk factors and adverse outcomes. Methods: It was a population-based cross-sectional analytical study. The study was carried out in Nashik District, having a large mountainous area. It included two randomly selected blocks, one tribal and one nontribal, in which interventions were planned in the later stage. For comparison, two adjacent blocks, one tribal and one nontribal, were also included. All women who had a pregnancy outcome in the preceding 12 months (01 April 2017 to 31 March 2018) were interviewed. Trained Accredited Social Health Activists under the direct supervision of Auxiliary Nurse Midwives and Medical Officers conducted the survey. Multivariate analysis was carried out to find the adjusted risk ratio of having a particular adverse outcome because of the specified potential risk factors.Results: A total of 9,307 women participated in the study. The prevalence of adverse pregnancy outcomes was abortion 4.1%; stillbirth 1.6%; preterm birth 4.1%; LBW 11.2%; congenital physical defect 2.6%. Prevalence of consanguineous marriage, heavy work during the last six months of pregnancy, pre-existing illness, tobacco consumption, direct exposure to pesticides and domestic violence during pregnancy was 17.6%; 16.9%; 2.2%; 5.6%; 2.3%; and 0.8%, respectively. Risk factors that were significantly associated with abortion include existing illness at the time of conception and performing heavy work in the last six months of pregnancy. Consanguinity, tobacco consumption during pregnancy and pre-existing illness were identified as risk factors for stillbirth. Significant risk factors of LBW were heavy work in the last six months of pregnancy, pre-existing illness and residence in a tribal area. Conclusion: The survey showed that risk factors differentially affect outcomes of pregnancy. Preconception and antenatal care should include counselling about consanguineous marriages, identifying and managing a pre-existing illness, avoiding tobacco consumption in the prenatal and natal period, and avoiding heavy work during pregnancy.

Abstract Background The preconception phase of women’s life cycle is critical but comparatively ignored. The presence of health risks is judged as hazardous to the wellbeing of women and their offspring. This study aimed to estimate the prevalence of various pregnancy outcomes and assess the association between certain risk factors and adverse outcomes. Methods As a part of a preconception care intervention project, a baseline survey was conducted in four blocks of Nashik District, India. In this population-based cross-sectional analytical study, we compared cases in the study group (randomly selected one tribal and one non-tribal block) with those of the control group (one tribal and one non-tribal block). A comparison was also made between the tribal and non-tribal blocks in each group. All women who had a pregnancy outcome in the preceding 12 months (01 April 2017 to 31 March 2018) were interviewed. Trained Accredited Social Health Activists conducted the survey under the direct supervision of Auxiliary Nurse Midwives and Medical Officers. Multivariate analysis was carried out to find the adjusted prevalence ratio of having a particular adverse outcome because of the prespecified potential risk factors. Results A total of 9307 women participated in the study. The prevalence of adverse pregnancy outcomes was as follows: abortion in 4.1%, stillbirth in 1.7%, preterm birth in 4.1%, low birth weight in 13.2%, and congenital physical defect in 2.8%. Prevalence of parental consanguinity, pre-existing maternal illness at conception, heavy work during the last six months of pregnancy, tobacco consumption, alcohol consumption, direct exposure to pesticides and domestic violence during pregnancy was 18.5, 2.2, 18.7, 5.6, 0.5, 2.3, and 0.8% respectively. Risk factors associated with abortion included pre-existing illness and heavy work in the last six months of the pregnancy. Consanguinity, tobacco consumption during pregnancy and pre-existing illness were identified as risk factors for stillbirth. Significant risk factors of low birth weight were heavy work in the last six months of pregnancy, pre-existing illness and residence in a tribal area. Conclusion There is a need to emphasize on maternal behaviour, including tobacco consumption, and heavy work during pregnancy, as well as on parental consanguinity and pre-existing maternal illnesses, in order to achieve the best possible pregnancy outcomes.

Adverse Pregnancy

Abstract Background Tobacco use during pregnancy is the most important modifiable risk factor associated with adverse pregnancy outcomes, increasing the risk of preterm birth, intrauterine growth restriction and sudden infant death syndrome. Fewer than half of pregnant smokers can quit on their own. Identifying safe and effective therapies to prevent tobacco-related adverse pregnancy outcomes and/or increase smoking cessation in pregnant women would have a substantial public health impact. Cigarette smoking is associated with a relative deficiency in circulating n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) levels. A recent analysis found that smokers taking n-3 LCPUFAs during pregnancy had a reduction in preterm labor risk when compared to non-smokers. Studies have shown that supplemental n-3 LCPUFAs may also reduce nicotine cravings and daily cigarette use. Thus, smokers may benefit from supplemental n-3 LCPUFAs by lowering the risk of preterm labor and/or increased smoking cessation. To address important remaining knowledge gaps, we propose the Investigating N-3 Fatty Acids to prevent Neonatal Tobacco related outcomeS (INFANTS). Methods The INFANTS study is a multicenter, randomized, double-blind, placebo-controlled study that will randomize 400 pregnant smokers to either supplemental n-3 LCPUFAs or placebo. Participants will be enrolled between 12 and 24 weeks’ gestation and followed until 6 weeks after delivery. We will recruit from clinical centers throughout Middle Tennessee. We will assess smoking behavior after 12 weeks of supplementation using self-report and validated biomarkers of tobacco exposure. We will measure response to supplementation using biological markers of n-3 LCPUFA status. Our primary endpoint will be preterm labor as reflected by gestational age at delivery. Our secondary endpoint will be change from baseline in cigarettes per day at 12 weeks. Discussion This study tests the hypothesis that smoking-induced n-3 LCPUFA deficiencies contribute to tobacco-related adverse pregnancy outcomes and that supplementation of n-3 LCPUFAs in pregnant smokers may prevent these complications. If our study demonstrates that supplemental n-3 LCPUFAs are effective at reducing the risk of tobacco-related adverse neonatal outcomes and/or reducing tobacco use during pregnancy, our results could have an immediate and major impact on pregnancy care and neonatal outcomes.
