Abstract Introduction Low birthweight (LBW) is a significant public health issue, and maternal smoking is the most prevalent preventable cause of LBW. But there is limited evidence on association of LBW among children and cigarette smoke exposure in mothers in China. In this cross-sectional study, we try to explore if the LBW in children is positively associated with mothers’ prenatal cigarette smoke exposure. Methods We selected 8, 586 mothers and their singleton children in 2018 in Songjiang district, Shanghai. Birthweight of children and gestational weeks of mother was identified by birth records in the hospital, we classified mothers’ prenatal cigarette smoke status into the first-hand smoke (FHS) exposure and the second-hand smoke (SHS) exposure. We use SAS 9.1.3 software to calculate the prevalence of children’s LBW and the prevalence of mothers’ prenatal cigarette smoke exposure including FHS and SHS. Chi-square test and logistic regression were used to analyze the difference. Results In 8, 586 women, The prenatal FHS and SHS exposure prevalence was 0.9 and 20.8%, respectively. The mean birthweight of children was 3315.5 g with a standard deviation of 497.2 g, the mean birthweight was 167.7 g and 66.1 g lower in children born to mothers with prenatally FHS and SHS exposure compared with those children whose mother were not exposed, respectively. The children’s LBW prevalence was 4.7% in this study. By comparing with children whose mother were not exposed, the LBW prevalence was higher among children whose mother were prenatally exposed to FHS [OR (Odds Ratios) = 2.91, 95% confidence interval (CI) (1.49, 5.68)], and SHS [OR = 2.35, 95% CI (1.90, 2.89)]. Conclusions Children’s LBW is positively associated with mothers’ prenatal tobacco smoke exposure both for FHS and SHS. So implementing tobacco control measures is crucial to lower smoking prevalence among women, and decrease smoking prevalence of their family members as well as work fellows.

Purpose: This study assesses the validity of hair nicotine as a biomarker for secondhand smoke (SHS) exposure. Although most biomarkers of tobacco-smoke exposure have a relatively short half-life, hair nicotine can measure several months of cumulative SHS exposure. Design: A cross-sectional study of hospitality-industry workers. Method: Hair samples were obtained from 207 bar and restaurant workers and analyzed by the reversed-phase high-performance liquid chromatography with electrochemical detection (HPLC-ECD) method. Self-reported tobacco use and sources of SHS exposure were assessed. Findings: Higher hair-nicotine levels were associated with more cigarettes smoked per day among smokers and a greater number of SHS-exposure sources among nonsmokers. Number of SHS exposure sources, gender, number of cigarettes smoked per day, and type of establishment predicted hair-nicotine levels. Discussion: Hair nicotine is a valid measure of SHS exposure. It may be used as an alternative biomarker to measure longer term SHS exposure.

Oxidative Effects

<b><i>Objective:</i></b> Cigarette smoking is a life-threatening habit that has rapidly spread in every socioeconomic part of the public worldwide. There exist mechanisms of nicotine delivery available to use in the hope of halting cigarette smoking, and the electronic cigarette (EC) is one of the common methods used for tobacco smoking replacement. This study aimed to investigate experimentally the oxidative effects of tobacco smoke and EC smoke which contain nicotine. <b><i>Method:</i></b> We constructed smoke circuit rooms for exposing the rats to EC or tobacco smoke. Three groups were created, the control group (<i>N</i> = 8); the electronic cigarette group (<i>N</i> = 8), exposure to electronic cigarette smoke for 2 h per day; and the tobacco group (<i>N</i> = 8), exposure to traditional cigarette smoke for 2 h per day. After the first and second week of exposure, blood samples were obtained, and serum oxidative stress index (OSI), paraoxonase 1 (PON1) activity, and prolidase levels were evaluated. <b><i>Results:</i></b> Higher values of OSI and prolidase levels were detected in the first week of EC or tobacco smoke exposure in both study groups (<i>p</i> &#x3c; 0.001) when compared with the control group, and partial decrements were observed in the second week. By contrast, elevated PON1 levels were observed in the second week after EC or tobacco smoke exposure. The highest OSI levels were observed in the tobacco smoke group (<i>p</i> &#x3c; 0.001). The lowest values of PON1 levels were detected in the first week of the electronic cigarette smoke group, and this decremental value was statistically different than normal, the second week of the electronic cigarette smoke group, the first week of the traditional cigarette smoke exposure group, and the second week of the traditional cigarette smoke exposure group values (<i>p</i> &#x3c; 0.000). <b><i>Conclusion:</i></b> Our results indicate that EC smoke induced oxidative stress. Therefore, ECs are potentially risky for human health and can lead to important health problems.

IntroductionThe workplace remains a significant source of secondhand smoke (SHS) exposure. This pollutant is known to be associated with respiratory and cardiovascular problems, but its effects on specific pulmonary function parameters remain largely unexplored. The objectives of this study were to measure SHS exposure among non-smoking employees of bar and restaurants in Santiago, Chile and to evaluate the effects of such exposure on pulmonary function.MethodsCross-sectional design. The study sample included non-smoking workers from 57 restaurants and bars in Santiago, Chile. The outcome variable was pulmonary function and the exposure variables were urine cotinine concentration, a biomarker for current SHS exposure, and years of SHS exposure in the workplace as proxy of chronic exposure. Personal and occupational variables were also recorded. Data analysis was performed using linear regression models adjusted by confounders.ResultsThe median age of the workers was 35 years and the median employment duration at the analysed venues was 1 year. Workers in smoking facilities reported greater SHS exposure (36 hours per week) than workers in smoke-free locations (4 hours per week). Urine cotinine levels were inversely correlated with forced vital capacity, but the finding was not statistically significant (β=−0.0002; 95% CI −0.007 to 0.006). Years of exposure to SHS showed to be significantly associated with forced expiratory flow25/75(β=−0.006; 95% CI −0.010 to −0.0004).ConclusionThese findings suggest that cumulative exposure to SHS at work may contribute to deterioration of pulmonary function in non-smoking employees.

ABSTRACT Background: Social economics and environmental factors contribute to low birthweight. Cigarette exposure to tobacco smoke in pregnant women has been discerned as an important risk factor for low birth weight. The purpose of this study was to investigate social economic determinants of birth weight using path analysis model. Subjects and Method: A case control study was carried out at Asembagus community health center, Situbondo, East Java. The study population was children aged 0-1 years. A sample of 150 children with normal birthweight and 50 children with low birth weight was selected randomly. The dependent variable was low bierthweight. The independent variables were maternal age, maternal employment status, family income, maternal knowledge, and cigarette smoke exposure. The data were collected by questionnaire and analyzed by path analysis. Results: The risk of low birthweight was directly and positively associated with maternal age <20 or ≥35 years (b= 1.78; 95% CI= 0.83 to 2.73; p<0.001), low maternal education (<Senior high school) (b= 0.93; 95% CI= 0.00 to 1.86; p= 0.049), mother work outside the home (b= 1.24; 95% CI= 0.26 to 2.22; p= 0.013), low family income low (b= 1.33; 95% CI= 0.42 to 2.24; p= 0.004), low maternal knowledge (b= 1.17; 95% CI= 0.13 to 2.21; p= 0.026), and high cigarette smoke exposure (b= 1.11; CI 95%= 0.08 to 2.13; p= 0.035). The risk of low birthweight was indirectly and positively associated with maternal education, maternal knowledge, and family income. Conclusion: The risk of low birthweight is directly and positively associated with maternal age <20 or ≥35 years, low maternal education (<Senior high school), mother work outside the home, low family income low, low maternal knowledge, and high cigarette smoke exposure. The risk of low birthweight is indirectly and positively associated with maternal education, maternal knowledge, and family income.

Background Environmental tobacco smoke has been consistently linked to negative health outcomes, especially in children, including an increased susceptibility to infections. Cigarette smoking has a depressive effect on interferon-γ (IFN-γ). Serum cotinine is a marker of exposure to smoke.Objective To determine the association between serum cotinine and interferon-γ (IFN-γ) levels in children with household tobacco smoke exposure.Methods We conducted a cross-sectional study at the Tumumpa and Singkil Districts of Manado, Indonesia, from February to May 2012. Subjects were collected by consecutively sampling of healthy children aged 1-3 years who came to the integrated health posts. Seventy-four children were recruited and consisted of two groups of 37 subjects each, the tobacco smoke exposure group and the non-tobacco smoke exposure group. Blood specimens were collected from all subjects for laboratory blood tests of cotinine and IFN-γ levels. Results were analyzed by T-test and Pearson’s correlation analysis with a P<0.05 is considered as statistically significant.Results There was no significant correlation between serum cotinine and interferon-γ levels in the tobacco smoke exposure group. However, the interferon-γ level in the tobacco smoke exposure group was significantly lower than that of the non-tobacco smoke exposure group (P<0.0001).Conclusion Cotinine is not related to the interferon-γ level in children exposed to tobacco smoke, however, the interferon-γ level in children with tobacco smoke exposure is lower than in the non-tobacco smoke exposure group.

Abstract Focus of Presentation Tobacco has always been a major public health issue. Being tobacco a major risk factor for so many diseases, it has also become a matter of concern in current situation of the pandemic. Tobacco smoking is not only harmful for the person who is actively smoking but also to ones who are in the vicinity of that smoke. There is plenty of evidence regarding harmful effects of both tobacco and inhaling tobacco smoke passively. This passive smoke is known as Second Hand Smoke. The aim of the study was to estimate percentage and sources of Second Hand Smoke exposure among pregnant women. It was a cross sectional study conducted among pregnant women registered at a Primary health centre. Findings Out of total participants, 62% were exposed to Second hand smoke. 33% participants were exposed to SHS at home only, 24% at public places only and 5 % were the one exposed both at home and public places. More than half (69%) of the participants were having inadequate knowledge about the harms caused by Second hand smoke Conclusions/Implications More than half of the participants were exposed to Second hand smoke. Inadequate knowledge among the participants about adverse effects of SHS exposure and insufficient Key messages Smoke-free homes should be promoted and health-care providers should ask pregnant women about their exposure to SHS and inform about the harms of SHS exposure during anti natal visits.
