“…In contrast, this does not seem to be the case for blood eosinophils, which showed persistently elevated levels in former smokers without asthma. Similarly, the sputum eosinophil count was shown not to change, whereas FeNO was normalized, after smoking cessation in young asthmatics [42]. This effect may be mediated by persistent TSLP formation in the airways of former smokers [43].…”

“…This is highly relevant given the current knowledge of the negative effect of second-hand exposure to cigarette smoke, with the most relevant being the depressive effect on IFN-γ, but no change, or even an increase, in type-2 cytokines and serum IgE [39,40]. FeNO has previously been reported to return to expected levels within a few weeks after smoking cessation [41,42]. However, only a few subjects reported having quit smoking within the past few weeks in the NHANES material, making it difficult to study the the time course of the normalization of FeNO.…”

“…However, the smoking rate calculated from the cotinine test was two times higher than that from the self-reported smoking status 36. Moreover, a study evaluating the smoking of pregnant women (18–38 years) also showed that the smoking rate from the self-reported smoking status was 4.1% while that from the cotinine test was 10.7% 37. In a questionnaire survey on smoking women in Korea, 29.2% of women smokers in their 20s and 30s responded that they smoked only when they were alone, and 25% responded that their families knew about their smoking.…”

ObjectivesThere is a possibility of underestimation in the smoking rate surveyed by self-reported questionnaires. This study investigated the difference between the Korean female smoking rate as determined by self-reports and that determined by a biochemical test and elucidated the relationship between women's smoking and laryngeal disorders.DesignNationwide cross-sectional survey.Setting2008 Korea National Health and Nutrition Examination Survey.Participants1849 women who completed the health survey, urinary cotinine test and laryngoscope examinations.Main outcome measureThis study defined smokers as those with urine cotinine contents of 50 ng/mL and over. Confounding factors included age, level of education, household income, occupation and problem drinking in the past year. For statistical tests, OR and 95% CI were presented by using complex samples logistic regression.ResultsWhile there was no relationship between smoking as determined by a self-reported questionnaire and laryngeal disorders, smoking as determined by the urine cotinine test had a significant relationship with laryngeal disorders (p<0.05). After all the confounding factors were adjusted, those with urine cotinine concentrations of over 50 ng/mL had a 2.1 times higher risk of laryngeal disorders than those with urine cotinine concentrations of <50 ng/mL (OR=2.05, 95% CI 1.11 to 3.78) (p<0.05).ConclusionsThis national cross-sectional study verified that smoking is a significant risk factor for laryngeal disorders. Longitudinal studies are required to identify the causal relationship between smoking and laryngeal disorders.

“…Studies examining the association of education and income with SHS exposure during pregnancy are limited [4][5][6][7][8][9][10][11], while there is substantial evidence that those with lower education and/or lower income are more exposed to SHS than higher ones in the general population [1,[12][13][14][15][16]. Although education and income re ect the central dimension of social strati cation, they have different meanings in society; education is thought to capture knowledge and skills, while income measures material resources to enhance health [17].…”

“…Although education and income re ect the central dimension of social strati cation, they have different meanings in society; education is thought to capture knowledge and skills, while income measures material resources to enhance health [17]. Existing studies among pregnant women have mainly focused on education [4,6,[8][9][10][11], and the association between income and SHS exposure have rarely been examined [5,7]. To the best of our knowledge, no studies have examined the association of education and income with SHS exposure during pregnancy in Japan.…”

Background: Associations of education and income with secondhand smoke (SHS) exposure have been well documented in the general population. However, evidence among non-smoking pregnant women is limited, including in Japan. The purpose of the study was to examine the associations of education and income with SHS exposure among non-smoking pregnant women in Japan.Methods: We analyzed data from 17815 non-smoking pregnant women in Japan who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study from 2013 to 2017. SHS exposure was defined as indoor exposure to someone else’s cigarette smoke ≥1 day/week during pregnancy. Multiple logistic regression analyses were conducted to examine whether pregnant women’s educational attainment or equivalent household income was associated with SHS exposure, adjusting for age, work status, smoking history, partners’ education, and income/education. Stratified analyses by work status were also conducted.Results: The prevalence of SHS exposure during pregnancy was 34.0%; 29.4% among non-working women and 37.1% among working women. Lower educational attainment was associated with an increased risk of SHS exposure; the odds ratio of high school education or lower compared with university education or higher was 1.78 (95% confidence interval, 1.59–1.99). Lower equivalent household income was associated with an increased risk of SHS exposure; the odds ratio of the lowest compared with the highest level of income was 1.67 (95% confidence interval, 1.51–1.84). These associations did not differ between non-working women and working women.Conclusions: Pregnant women with lower education and/or lower household income had higher risks of SHS exposure in Japan. These findings imply that educational interventions and financial incentives are needed for pregnant women and their household smokers in helping to reduce SHS exposure among non-smoking pregnant women.
