Exposure To Secondhand Smoke

This study aimed to estimate the secondhand smoke (SHS) exposure using urinary cotinine (UCo) to prove that the SHS exposure could not be properly assessed by self-reporting (SR). In total, 28,574 nonsmokers aged >19 years were selected from the Korean National Health and Nutrition Examination Survey data (2009–2018). First, changes in the annual concentration of UCo were analyzed, and the annual SHS exposure rates were measured based on SR and UCo from 2009 to 2018. Then, the average UCo concentration and UCo-measured SHS exposure rate were confirmed according to the subjects’ characteristics. Finally, factors associated with the UCo-measured SHS exposure rate were identified based on multiple regression analysis. The findings showed that the annual UCo concentrations and self-reported SHS exposure rates dropped significantly over the past decade. In contrast, the UCo-measured SHS exposure rate indicated that >80% of nonsmokers are still exposed to SHS. Moreover, we found vulnerable groups using UCo-measured SHS exposure rate. In particular, the self-reported SHS exposure at home and in workplaces and house type was highly associated with SHS exposure. Thus, these findings indicate that the actual SHS exposure could not be properly assessed by SR and should be verified using a biomarker, such as UCo. Considering that even a short-term exposure can be harmful to health, the goal of the policy should be to keep cotinine concentration as low as possible.

Abstract Objective To examine the association of mixed electronic and conventional cigarette use and exposure to secondhand smoke with prediabetes. Methods Data from the 2014–2018 Korean National Health and Nutrition Examination Survey were analyzed. Prediabetes was defined as an HbA1C of 5.7–6.4%. Participants were categorized according to type of cigarette use and secondhand smoke exposure. Multiple logistic regression analysis was performed. Results Of the 22,385 participants without diabetes, 6,735 had prediabetes. Mixed cigarette use was associated with a 1.57-fold increase in the odds of prediabetes when compared with never smoking without exposure to secondhand smoke (odds ratio [OR] = 1.57, 95% confidence interval [CI] = 1.31–1.87), and a 1.27-fold increase when compared with conventional cigarette use only (OR = 1.27, 95% CI = 1.09–1.49). Participants who were current non-smokers but mixed users in the past had an increased risk of prediabetes (OR = 1.54, 95% CI = 1.06–2.23). However, there was no significant association between current non-smoking but only conventional cigarette use in the past and prediabetes. Among never-smokers, exposure to secondhand smoke significantly increased the risk of prediabetes (OR = 1.15, 95% CI = 1.03–1.28). Conclusions Mixed use of electronic and conventional cigarettes and exposure to secondhand smoke increased the risk of prediabetes.

Exposure to secondhand smoke (SHS), a major indoor air pollutant, is linked to increased cardiovascular morbidity and mortality, including cardiac arrhythmias. However, the mechanisms underlying the epidemiological findings are not well understood. Impaired cardiac autonomic function, indexed by reduced heart rate variability (HRV), may represent an underlying cause. The present study takes advantage of well-defined short-term SHS exposure (3 days, 6 h/day) on HRV and the susceptibility to arrhythmia in mice. With the use of electrocardiograph telemetry recordings in conscious mice, HRV parameters in the time domain were measured during the night after each day of exposure and 24 h after 3 days of exposure to either SHS or filtered air. The susceptibility to arrhythmia was determined after 3 days of exposure. Exposure to a low concentration of SHS [total suspended particle (TSP), 2.4 ± 3.2; and nicotine, 0.3 ± 0.1 mg/m3] had no significant effect on HRV parameters. In contrast, the exposure to a higher but still environmentally relevant concentration of SHS (TSP, 30 ± 1; and nicotine, 5 ± 1 mg/m3) significantly reduced HRV starting after the first day of exposure and continuing 24 h after the last day of exposure. Moreover, the exposed mice showed a significant increase in ventricular arrhythmia susceptibility and atrioventricular block. The data suggest that SHS exposure decreased HRV beyond the exposure period and was associated with an increase in arrhythmia susceptibility. The data provide insights into possible mechanisms underlying documented increases in cardiovascular morbidity and mortality in humans exposed to SHS.

Purpose: To examine locations of secondhand smoke (SHS) exposure among nonsmokers, 7 years after a statewide smoke-free policy. Design: Data collected via statewide, random digit dial telephone survey. Response rates were 64.7% for landline and 73.5% for cell phone. Setting: Minnesota, 2014. Participants: Representative sample of 7887 nonsmoking adults. Measures: Self-reported locations of SHS exposure and opinions on smoke-free restrictions. Analysis: Descriptive statistics and logistic regression. Results: A total of 35.5% of nonsmokers reported SHS exposure in the past 7 days. The greatest proportion of exposure occurred in community settings (31.7%) followed by cars (6.9%) and in the home (3.2%). Young adults were more likely to be exposed in a home or car than older adults. Nonsmokers living with a smoker were 39.6 (20.6-75.8) times more likely to be exposed to SHS in their home and 5.3 (4.1-6.8) times more likely to be exposed in a car, compared to those who did not live with a smoker. Conclusion: SHS exposure continues after comprehensive smoke-free policies restricted it from public places. Disparities in exposure rates exist for those who live with a smoker, are young, and have low incomes. Findings suggest the need for additional policies that will have the greatest public health benefit.

Abstract The main objective of this study was to estimate the cumulative mortality risk for lung cancer according to smoking status and exposure to secondhand smoke (SHS) in Japan. We applied a life-table method to estimate the cumulative risk. Estimated lifetime cumulative risk for 20-year-old non-smokers, former, and current smokers was 3.2%, 7.6%, and 14.9% for men and 1.9%, 5.6%, and 7.2% for women, respectively. For males, the estimated risk was 3.2% for non-smokers not exposed to SHS and 4.1% for non-smokers exposed to SHS. For females, the estimated risk was 1.9% for non-smokers not exposed to SHS and 2.4% for non-smokers exposed to SHS. Lifetime cumulative mortality risk differed greatly according to smoking status. Moreover, SHS exposure resulted in observable differences in lifetime mortality risk. This study may be useful for the development of tailored prevention programs.

Exposure To Secondhand Smoke

Abstract Background Findings on the association between exposure to secondhand smoke (SHS) and depression are contradictory. Comparability of existing research is limited due to varied methods and measures. This study examines the potential association between exposure to SHS and depression and a potential moderation by sex using representative data from Germany. Methods For our study, we used data from the German Health Update (GEDA) 2014/2015 on n = 10,274 never-smokers. We calculated a logistic regression model with an interaction term for potential sex-exposure interactions. We used the self-reported duration of exposure to predict current depression of any type as defined by the Patient Health Questionnaire PHQ-8 (score ≥ 10), accounting for a large number of confounders. Results In our sample, prevalence of depression was 8.8% in women and 5.3% in men. 90.4% were never or almost never exposed to SHS, while 7.1% were exposed < 1 h per day and around 2.5% reported being exposed for ≥1 h per day. While SHS exposure for < 1 h per day was not associated with current depression (OR = 1.54; 95%-CI: 0.93–1.61), SHS exposure for at least 1 h per day was associated with increased odds for current depression (OR = 1.59; 95%-CI: 1.08–2.35). No sex-specific differences were found. Conclusions Higher levels of SHS exposure are associated with current depression, although the nature and direction of the association are still unclear. We identified no differences in the association between men and women. More studies, particularly using longitudinal data, are needed to determine the nature of the association.

Exposure To Secondhand Smoke

Since the global enforcement of smoke-free policies, indoor smoking has decreased significantly, and the characteristics of non-smokers’ exposure to secondhand smoke (SHS) has changed. The purpose of this study was to assess the temporal and spatial characteristics of SHS exposure in non-smokers by combining questionnaires and biomarkers with time activity patterns. To assess SHS exposure, biomarkers such as cotinine and 4-(methylnitrosamino)-1-3-(pyridyl)-1-butanol (NNAL) in urine and nicotine in hair were collected from 100 non-smokers in Seoul. Questionnaires about SHS exposure and time activity patterns were also obtained from the participants. The analysis of biomarker samples indicated that about 10% of participants were exposed to SHS when compared with the criteria from previous studies. However, 97% of the participants reported that they were exposed to SHS at least once weekly. The participants were most exposed to SHS in the outdoor microenvironment, where they spent approximately 1.2 h daily. There was a significant correlation between the participants’ time spent outdoors and self-reported SHS exposure time (r2 = 0.935). In this study, a methodology using time activity patterns to assess temporal and spatial characteristics of SHS exposure was suggested. The results of this study may help develop policies for managing SHS exposure, considering the time activity patterns.

Exposure To Secondhand Smoke

Background: Exposure to secondhand smoke (SHS), or passive smoking, has been associated with chronic hypertension. However, little is known about the relationship between SHS and left ventricular (LV) hypertrophy, the most common complication of hypertension and a manifestation of cardiac end-organ damage. Hypothesis: SHS exposure is independently associated with LV mass. Methods: This analysis included 4,982 non-smoker participants (age 60.8±13.6 years, 57.8% women, 77.7% whites) from the Third National Health and Nutrition Examination (NHANES-III). Non-smoking was defined by self-report and serum cotinine ≤ 10 ng/dL, a biomarker for tobacco exposure. SHS was defined as serum cotinine level >1 ng/dL. LV mass was estimated using an electrocardiographic model developed and applied in NHANES-III then validated in the Cardiovascular Health Study. Multivariable linear regression was used to examine the cross-sectional association between SHS exposure (vs. no exposure) with estimated LV mass. In similar models, we also examined the associations of LV mass across quartiles of serum cotinine (reference group, 1 st quartile) and in subgroups stratified by race, sex, and hypertension status. Results: About 9.8% (n=489) of the participants were exposed to SHS. Exposure to SHS was associated with an estimated 2.9 gram increase in LV mass, with a dose-response relationship between higher serum cotinine and LV mass ( Table ). These results were consistent in men and women (interaction p-value= 0.31), whites and non-whites (interaction p-value= 0.21), and those with and without hypertension (interaction p-value= 0.88) Conclusion: In a racially diverse sample of non-smokers, SHS is associated with increased LV mass with a dose-response relationship between level of exposure and LV mass. These findings underscore the harmful effect of passive smoking on the cardiovascular system and highlight the need for more restrictions on smoking in public areas.
