“…Although cigarette smoking during pregnancy and lactation has been linked to several adverse pregnancy outcomes, smoking during pregnancy is still a prevalent behavior in many countries (Lange et al, 2018;Kondracki, 2019). In addition to active smoking, passive smoking (second hand smoke exposure) has been shown to have a high prevalence in low-and middleincome countries (Elf et al, 2018). Long-term direct and indirect CS-exposure (ETS, second hand smoking) causes a wide range of damaging health effects, including increased lung inflammation, protease activity, oxidant stress, and apoptosis (Gopal et al, 2016).…”

“…According to the World health Organization (WHO), over 80% of the world's 1.3 billion smokers live in low-and middle-income countries, and around 1.2 million deaths per year are attributable to ETS, worldwide. In addition, epidemiological studies have demonstrated high rates of ETS among the youth in these low-and middle-income countries (Wang et al, 2017;Elf et al, 2018). ETS contains the same range of tobacco smoke toxins as active smoking, therefore it is likely that ETS during pregnancy may also have important effects on fetal health.…”

Cigarette smoke exposure during pregnancy and lactation is associated with adverse pregnancy outcomes. Here, we investigated the effects of maternal smoke exposure on pregnancy and offspring immunity and explored whether, epidermal growth factor (EGF), an important growth-promoting factor in human colostrum and milk, might be a possible missing link in maternal smoke exposure and changes in infants’ immune responses. Pregnant BALB/c mice were exposed to either cigarette smoke or air during gestation and lactation, and effects on pulmonary inflammation in dams and immune responses in offspring were examined. Maternal smoke exposure increased airway hyperresponsiveness and accumulation of inflammatory cells in the lungs of pregnant dams compared to non-pregnant dams. The E-cadherin protein expression was reduced in mammary glands of cigarette smoke-exposed pregnant dams. EGF levels were higher in mammary glands and serum of smoke-exposed pregnant dams compared to air-exposed pregnant dams. Offspring from cigarette smoke-exposed dams exhibited elevated levels of IL-17A, MCP-1, IL-22, and IL-13 in anti-CD3 stimulated spleen cell culture supernatants. EGF levels were also increased in serum of offspring from smoke-exposed dams. A positive correlation was observed between serum EGF levels and neutrophil numbers in bronchoalveolar lavage fluid of the dams. Interestingly, IL-17A, MCP-1, IL-22, IL13, and IFN-γ levels in anti-CD3 stimulated spleen cell culture supernatants of male pups also showed a positive correlation with EGF serum levels. In summary, our results reveal that maternal smoke exposure predisposes dams to exacerbated airway inflammation and offspring to exacerbated immune responses and both phenomena are associated with elevated EGF concentrations.

“…Similar results were found in infants, with correlations from r=0.35 with plasma nicotine and number of days the infant was exposed to TSE, to a maximum of r=0.66 between hair nicotine and number of cigarettes smoked per day 27 . Another recent study found a large range of correlations, from -0.2 to +0.4, which were not statistically significant, between parent-reported measures and air and hair nicotine 28 . However, one study found higher and statistically significant correlations between maternal hair nicotine and parent-reported measures (r=0.46–0.74) 29 .…”

“…is possible to assess SHS exposure over a longer period compared to the other three methods. Finally, nail nicotine assessment is the fth method of analysis, which may vary with age [5].The importance of SHS has made researchers employ several approaches to assess SHS exposure, including the use of questionnaires as a popular method due to their low cost and non-invasive nature [9]. In this regard, Nondahl et al classi ed SHS exposure into three settings, that is, home, work, and social settings.…”

“…They compared the results of their questionnaire with hair and saliva cotinine measurements and found a positive correlation between the questionnaire results and laboratory ndings [10]. Moreover, Elf et al compared the questionnaire results with hair nicotine ndings; in their questionnaire, they also included questions for children exposed to SHS [9]. SHS can both occur in children and adults.…”

Background The exposure of non-smokers to tobacco smoke is known as secondhand smoke (SHS) exposure, which can significantly affect their health. Due to the unavailability of a standardized questionnaire to assess SHS exposure, this study aimed to design Psychometric Properties of SHS Exposure Assessment Tools. Methods The present study was an assessment tool study conducted on 160 adults with SHS exposure who were citizens of Zanjan, Iran, in 2020. In the first step, we carried out a literature review for creating tool items to assess SHS exposure. The psychometric properties steps include face validity, content validity, construct validity and reliability. Exploratory Factor Analysis with the Principal component factor analysis method was used to test the construct validity of the scale. The reliability of the tools was tested using Cronbach’s alpha coefficient. Results The KMO index of adequacy was measured to be 0.822 that more than 0.7, indicating the adequacy of cases for factor analysis. The questionnaire was approved with four factors and 26 items which explained a cumulative variance of 0.57%. The face validity of the questionnaire was evaluated; all items had an impact score above 1.5. Also, the content validity ratio and the content validity index were both adequate. Finally, the reliability of the questionnaire was approved based on Cronbach’s alpha coefficient of 0.88. Conclusion In the primary assessment validity and reliability of tools were adequate for the assessment of SHS exposure in adults. Further studies are suggested to assess the specificity and sensitivity of this tool.

Secondhand Smoke Exposure and Validity of Self-Report in Low-Income Women and Children in India

Abstract: BACKGROUND: There is limited validation of self-reported measures for secondhand smoke (SHS) exposure in low-and middle-income countries. We evaluated the validity of standard self-reported measures among women and children in urban India.
