Exposure Levels

ObjectivesTo assess the levels of secondhand smoke (SHS) exposure before and after the implementation of the Tobacco Free Cities (TFC) initiative.DesignCity-wide representative, cross-sectional surveys (Tobacco Questions for Surveys, TQS) were conducted in each participating city before and after the implementation of TFC.SettingFive large Chinese cities (Chengdu, Chongqing, Wuhan, Xiamen and Xi’an) participated in the TFC initiative.ParticipantsA total of 10 184 adults participated in the 2015 TQS survey, and 10 233 adults participated in the 2018 TQS survey, respectively.InterventionsThe TFC initiative, which included targeted media campaigns, educational programmes, implementing city-wide smoke-free policies and providing cessation interventions, was implemented in these five cities between 2015 and 2018.Main outcomeSelf-reported past 30-day (P30D) SHS exposure in indoor workplaces, restaurants and homes.Data analysisThe pre-TFC and post-TFC SHS exposure levels were compared among all residents and among certain population subgroups. Multivariate logistic regressions were used to estimate the adjusted associations between P30D SHS exposure and individual characteristics.ResultsAcross all five cities, the overall rate of self-reported P30D SHS exposure declined in indoor workplaces (from 49.6% (95% CI: 46.4% to 52.8%) to 41.2% (95% CI: 37.7% to 44.7%)), restaurants (from 72.4% (95% CI: 69.8% to 74.9%) to 61.7% (95% CI: 58.7% to 64.7%)) and homes (from 39.8% (95% CI: 36.9% to 42.7%) to 34.7% (95% CI: 31.5% to 37.8%)) from 2015 to 2018. These declines were statistically significant after controlling for individual characteristics. The P30D SHS exposure was associated with sex, age, education level, occupation and current smoking status. The associations varied by venues.ConclusionsOur analysis showed that compared with the nationwide SHS exposure levels reported in concurrent national surveys, the declines in P30D SHS exposure in five Chinese cities that implemented the TFC initiative were larger in indoor workplaces and restaurants. Our findings suggest that the TFC initiative was effective in reducing SHS exposure in Chinese cities.

Background: Secondhand Smoke (SHS) exposure is known to be associated with various cardiovascular and respiratory problems but its effect on pulmonary function remains unexplored. This study was done to evaluate the effect of Secondhand Smoke (SHS) exposure on lung function among non-smoking population.Methods: This cross-sectional study was conducted in Bahour, Pondicherry from 2017-2018.  350 participants, age 40 year and older, with no respiratory symptoms or prior lung diseases were included in this study. Both self-reported history and measurement of urinary cotinine level were used to evaluate the smoking status. Spirometry data, including FVC and FEV1 were used to assess lung function. Diverse variables between groups were compared using T- test and Chi-square test. Analysis of covariance (ANCOVA) adjusted for age, height, alcohol consumption, and level of exercise was used to see any statistical differences in lung function parameters between non-SHS exposed and SHS-exposed groups.Results: Among 350 non-smokers, 120 were SHS-exposed. The urinary cotinine levels clearly distinguished SHS exposure, and the mean urinary cotinine levels were 7±0.3 and 11±0.4 in non-SHS exposed group vs SHS-exposed group, respectively. However, both groups had no significant difference in lung function and was found normal.Conclusions: SHS exposure urinary cotinine is a valuable marker.

ObjectiveThe objective of this study was to evaluate the influence of secondhand smoke (SHS) exposure during childhood on type 2 diabetes mellitus, hypertension, hyperlipidaemia and coronary heart disease among Chinese non-smoking women.MethodsIn this cross-sectional study, the SHS exposure data in childhood were obtained using a questionnaire survey. Self-reported childhood SHS exposure was defined as the presence of at least one parent who smoked during childhood.ResultsOf the 6522 eligible participants, 2120 Chinese women who had never smoked were assessed. The prevalence of SHS exposure in the entire population was 28.1% (596). SHS exposure during childhood was not significant for the standard risk factors of type 2 diabetes mellitus (p=0.628) and hypertension (p=0.691). However, SHS was positively associated with hyperlipidaemia (p=0.037) after adjusting for age, obesity, education status, physical activity, alcohol consumption, current SHS exposure status, diabetes mellitus and hypertension. In addition, childhood SHS increased the occurrence of coronary heart disease (p=0.045) among non-smokers after further adjusting for hyperlipidaemia.ConclusionSHS exposure during childhood is associated with prevalent hyperlipidaemia and coronary heart disease in adulthood among non-smoking Chinese women.

The Impact

9549 Background: The impact of BC on HRQL is poorly understood. To our knowledge, this is the first and largest cross-sectional study that compares HRQL of patients before and after BC diagnosis (DX). Methods: Our sample included 1,476 BC patients (≥ age 65) within the SEER-Medicare Health Outcomes Survey linkage database (1998-2007). We assessed differences in HRQL as measured by SF-36 physical (PCS) and mental (MCS) summary scores in patients who had a survey >1 yr before BC DX (n=620) and those who had a survey after BC DX (n=856). We compared groups by year from BC DX using regression analyses and results were adjusted for cancer stage, race, gender, age at BC DX, marital status, education, income, smoking status, activity of daily living (ADLs), and non-cancer comorbidities. Results: Patients who had a survey after BC DX were diagnosed with BC at an older age than those with a survey before BC DX (55.9% at age ≥75 yr vs. 36.8%; P<0.01). Other baseline demographic and socioeconomic characteristics were similar. Baseline HRQL were poor in patients before DX (PCS mean=40.1; MCS mean=51.1) with 50.6% and 31.9% of them having comorbidity score ≥2 and impairment of ≥1 ADLs, respectively. After BC DX, significant decreases in PCS (-2.7; 95% CI -3.8,-1.7) and MCS (-1.4; 95% CI -2.6, -0.3) were observed, with HRQL being lowest in those who had BC DX within 1 yr (PCS mean= 36.6; MCS mean=49.7). Declines in PCS during the <1, 1-3, 3-5, 5-10, and 10+ yr periods after BC DX compared to before BC DX were -3.8 (P<0.01), -2.5 (P<0.01), -2.2 (P=0.01), -1.1 (P=0.19) and -0.8 (P=0.57) whereas decreases in MCS were -2.0 (P=0.01), -2.2 (P<0.01), -1.2 (P=0.21), -0.1 (P=0.92), -0.8 (P=0.62) respectively. More advanced BC, lower educational level, higher comorbidity score, and impaired ADLs were significantly associated with both worse PCS and MCS after BC DX (P<0.05). Lower income and older age at BC DX showed significant association with low PCS (P<0.05). Conclusions: Older BC patients are a vulnerable population with poor baseline HRQL. HRQL of patients after BC DX is significantly worse than HRQL of patients before DX, possibly due to therapy and/or disease progression. Future research that evaluates interventions to improve HRQL in older patients with BC is critical.

Background: The prevalence of tobacco consumption in Thailand has gradually declined; however, the prevalence of exposure to secondhand smoke (SHS) is still high. The objective of this study is to estimate the prevalence of SHS exposure and examine the association between exposure to SHS and depressive symptoms among schoolchildren, and test for moderation by the number of smokers in household. Methods: We conducted a cross-sectional study of 1105 schoolchildren. Socioeconomics factors, depressive symptoms and exposure to SHS variables were collected. We used the chi-square test for testing the factors associated to SHS exposure. In addition, we used the Mantel Haenszel test for testing interaction effect of depression to SHS exposure by the number of smokers in home. Multiple logistic regression was used to test the factors related to SHS exposure adjusted for confounders. Results: The prevalence of exposure to SHS was 58.2% (95%CI: 55.2, 61.1). The schoolchildren with abnormal depression status were 1.8 times more likely to have been exposed to SHS (95%CI: 1.3, 2.5). In addition, the number of smokers in the home did not modify the association between exposure to SHS and depressive symptoms (P: 0.964). Conclusions: An association between exposure to SHS and depressive in schoolchildren was observed, but this relationship was not affected by the number of smokers in children’s homes.

ABSTRACT Objective: to analyze the association between individual characteristics and housing context with smoking and alcohol consumption during pregnancy. Methods: a cross-sectional study with a probabilistic sample of 3,580 pregnant women who underwent prenatal care in the Unified Health System in 2019. The outcomes were firsthand, secondhand smoke and alcohol consumption during pregnancy. Individual characteristics and the living environment were used as exploratory variables. Results: living in a neighborhood with episodes of violence, without social cohesion and without urban elements that encourage physical activity was associated with smoking. Alcohol consumption during pregnancy was associated with living in environments that do not encourage physical activity. Smoking was also associated with lower income and education. Conclusions: individual characteristics and the living environment are associated with smoking, secondhand smoke and alcohol consumption during pregnancy.

Abstract Background In the USA and Canada, cars are a major source of secondhand smoke (SHS) exposure among youth. Little is known about the magnitude of this public health problem in European countries. In this report, we study SHS exposure in vehicles among adolescents across 7 member states of the European Union (EU), with a particular focus on socio-economic characteristics and adolescents’ smoking environment. Methods Data on self-reported SHS exposure in cars during the past seven days was obtained from the 2016/17 cross-sectional SILNE-R study from 14-17-year old adolescents in EU seven countries (N = 10,481). We applied two multivariate logistic regression models with sociodemographic characteristics and mediating smoking-related factors. Results SHS car exposure varied widely across the 7 EU countries: 6% in Finland, 12% in Ireland, 15% in the Netherlands, 19% in Germany, 23% in Portugal, 36% in Belgium and 43% in Italy. Low paternal educational levels were strong correlates of SHS exposure in cars as well as migration background. Other correlates were one’s own smoking status and the relation to the family and peer smoking environment, such as parental smoking, permissive smoking rules at home, and best friends smoking. Conclusions In most of these seven countries, a considerable proportion of youth, particularly those from disadvantaged backgrounds, is exposed to SHS in cars. There is a need to ensure adoption and sustained enforcement of smoke-free car legislation. Given the long-term effectiveness of smoke-free car policies, our finding suggests that such policies can contribute towards reducing smoking inequalities. Key messages We assessed adolescent secondhand smoke (SHS) exposure in cars in 7 EU countries, which varies widely, ranging from 6% in Finland to 43% in Italy. The findings point to a social gradient, environmental factors in SHS car exposure and call for the rapid implementation of smoke-free car legislation.

Abstract Background This study aims to identify sociodemographic characteristics associated with secondhand smoke (SHS) exposure and the adoption of smoking bans in homes with children in Spain Methods We performed, in 2016, a cross-sectional study to a representative sample of Spanish households with children under 12 years old. We administered a telephone survey to the parents asking about smoking patterns at home, children’s SHS exposure and sociodemographic characteristics. Poisson regression models with robust variance were built to assess sociodemographic characteristics associated with household SHS exposure and the adoption of smoking rules. Results In this study participated 2411 families, 25.8% of which reported exposure at home and 84.4% implemented smoking bans. SHS exposure was associated with having one (aPR = 2.09; 95% CI: 1.43–3.04) or two Spanish parents (aPR = 1.71; 95% CI: 1.24–2.36), lower educational attainment (primary: aPR = 1.74; 95% CI: 1.45–2.10; secondary: aPR = 1.37; 95% CI: 1.17–1.60 compared with university studies), a family structure different from two-parent family (aPR = 1.38; 95% CI: 1.14–1.67) and parents between 31 and 40 years (aPR = 0.75; 95% CI: 0.57–0.99) and 41–50 years (aPR = 0.62; 95% CI: 0.47–0.81) compared with 18- to 30-year-old parents. The adoption of smoking bans was associated with two-parent family (aPR = 1.09; 95% CI: 1.01–1.17), living with non-smokers (aPR = 1.46; 95% CI: 1.31–1.62), parents of foreign origin (aPR = 1.09; 95% CI: 1.04–1.14) and younger children (0–3 years: aPR = 1.05; 95% CI: 1.01–1.09) compared with the oldest children (8–11 years). Conclusion The parent’s origin and the family structure were associated with SHS exposure and the adoption of smoking bans at home. Moreover, the number of smokers living at home was relevant for the adoption of smoking bans, and the educational attainment for SHS exposure. These factors should be taken into consideration when designing or implementing smoke-free home programmes.

Worldwide, 40% of children, 33% and 35% of male and female non-smokers respectively, were regularly exposed to second-hand smoke indoors. The practice to avoid second hand smoke at home are mostly individual-driven although in public places SHS can be executed by laws and policies such as gazetted smoke-free zones. A cross sectional study was conducted at Flat Bukit Kecil, Kuala Terengganu involving 211 respondents. Self-administered questionnaire was used and data were analysed. Descriptive statistics and Pearson chi square were employed. Findings revealed significant associations between socio demographic factors; gender (p=0.002), ethnicity (p=0.006), and occupational status (p=0.014) with SHS exposure. SHS exposure was also found to be significantly associated with respondents’ vaping (p=0.035) and smoking status (p<0.001), and respondents with existing tobacco related morbidity (p=0.040). In conclusion, the prevalence of SHS among adult residents in Flat Bukit Kecil, Kuala Terengganu (57.8%) was higher in comparison with other local studies. Restaurants were found to be the most common place of SHS exposure followed by workplace and home. In general, the residents demonstrated poor attitude and practice towards SHS whilst knowledge was good on SHS. Malay smoker residents, aged above 40 years old, employed, allowed guests smoking inside the house and had a family history of tobacco related diseases were more likely to be exposed to SHS than its counterpart.   Keywords: adults, KAP, low income residence, SHS

Biomedical waste (BMW) management is an essential practice of healthcare professionals (HCPs) for preventing health and also environmental hazards. Coronavirus disease (COVID-19) has become a global pandemic, posing significant challenges for healthcare sectors. A cross-sectional study was performed to assess the knowledge, practice, and attitude on BMW management among HCPs when taking care of patients with COVID-19 and associated with demographic variables. From Al-Ahsa healthcare sectors, 256 HCPs were selected randomly, of which 105 (41%) had excellent knowledge, 87 (34%) had good knowledge, and 64 (25%) had poor knowledge with a mean score of 13.1 ± 3.6. A higher mean score was (14.4 ± 3.2) obtained by physicians, and (13.6 ± 3.8) nurses than the other HCPs. Regarding practice, 72 (28.1%) HCPs used and discarded PPE while handling biomedical wastes. Additionally, 88 (34.4%) followed proper hand hygiene before and after each procedure and whenever needed. Physicians, nurses, and respiratory therapists had a more favorable attitude than other HCPs. There was a statistically significant association found among knowledge level and educational qualification (p < 0.0001), gender (p < 0.001), and work experience (p < 0.05). Emphasis is needed to train all HCPs regarding proper BMW management during this pandemic to prevent infection transmission.
