Exposure to Tobacco Smoking in Vehicles, Indoor, and Outdoor Settings in Germany: Prevalence and Associated Factors

PM2.5 Concentrations of Outdoor Tobacco Smoke at Different Distances From the Smoking Source: Is There an Optimal Distance for a Designated Smoking Area?

INTRODUCTION

Many countries have enacted indoor smoke-free policies, and some have established outdoor nonsmoking areas. However, no clear standard for determining the optimal distance for these outdoor nonsmoking zones remains. This study aimed to evaluate outdoor tobacco smoke (OTS) exposure up to a distance of 21 m and to identify factors influencing OTS levels.

METHODS

To assess OTS levels, PM2.5 concentrations were measured at distances of 6, 12, 15, 18, and 21 m using real-time aerosol monitors. Between August and October 2022, a total of 164 measurements were undertaken. The background PM2.5 concentration was gauged for 5 minutes before smoking commenced and then re-measured 3 minutes during smoking. OTS levels were determined by calculating the difference between the average background PM2.5 and the average PM2.5 concentrations during smoking. A one-sample t test was employed to ascertain if the OTS levels at each distance were significantly elevated compared to 0 µg/m3. Furthermore, a multiple linear regression analysis was conducted to determine the factors influencing OTS levels.

RESULTS

The mean OTS levels recorded at all specified distances significantly surpassed 0 µg/m3. The regression analysis revealed that the OTS levels correlated significantly with distance and wind speed. Specifically, OTS levels diminished as distance expanded and wind speed reduced.

CONCLUSIONS

OTS levels, even at 21 m, were significantly greater than 0 µg/m3. Our results provide robust evidence supporting the establishment of outdoor nonsmoking zone up to 21 m.

IMPLICATIONS

Outdoor tobacco smoke (OTS) level was determined by PM2.5 concentration. The OTS levels significantly exceeded 0 µg/m3 at every measured distance up to 21 m. In the regression model, OTS levels notably correlated with distance and wind speed. OTS levels diminished as distance expanded and wind speed reduced.

The effects of planned education given to parents on smoking in the home environment and passive exposure of children aged 0-5: A quasi-experimental pre-post intervention study from Turkey

PURPOSE

This study was carried out to determine the effects of planned education given to parents on smoking status at home and on children's passive smoking exposure.

DESIGN AND METHODS

This quasi-experimental study was conducted with the inclusion of 40 parents with at least one child between the ages of 0 and 5 and smoking in their homes, who were registered at a Family Health Center in a city center in the Central Anatolia Region of Turkey, from 1 September 2019 to 30 June 2020. The data of the study were collected using Participant Screening Form, a Personal Information Form, the Fagerstrom Test for Nicotine Dependence, a Smoking Behaviors and Precautions at Home Form, and a Measurement and Follow-up Form. The collected data were analyzed using the SPSS 23.0 package software.

RESULTS

In the follow-ups after the planned smoking cessation training given to the parents, the carbon monoxide measurements at their homes decreased significantly throughout the four follow-ups, the number of parents who presented to the smoking cessation outpatient clinic increased, and the number of smoking parents decreased (p < 0.05).

CONCLUSIONS

It was concluded that the planned education that was given to smoker parents reduced the smoking rates of the parents, lowered the carbon monoxide values measured in their home environments, and thus, it was effective in reducing the passive exposure of their children at the ages of 0 to 5 years to cigarette smoke.

PRACTICE IMPLICATIONS

Parents who are addicted to cigarettes should be encouraged not to smoke at home, and homes should be included in closed environments where smoking is prohibited.

Public support for car smoking bans in Poland: a 2022 national cross-sectional survey

OBJECTIVE

The objectives of this study were to assess the prevalence of self-reported secondhand smoke exposure in cars among adults in Poland and to characterise public attitudes towards the implementation of the ban on smoking in cars with children.

DESIGN

Cross-sectional survey was carried out between 4 March 2022 and 7 March 2022 on a national sample of 1090 adult Polish residents. The questionnaire included 12 closed questions on smoking behaviours, secondhand smoke exposure as well as attitudes towards different smoke-free laws.

PARTICIPANTS

Data were obtained from 1090 individuals, aged 18-84 years, 52.6% were females.

RESULTS

Almost every fifth respondent (17.7%) declared secondhand smoke exposure in cars in the past 30 days (31.8% of smokers and 12.0% of non-smokers; p<0.001). Lack of the implementation of smoke-free home rules (aOR 2.92, 95% CI 1.99 to 4.29; p<0.001), age 18-29 years (aOR 2.06; 95% CI 1.16 to 3.67; p=0.01), current smoking (aOR 1.99, 95% CI 1.37 to 2.90; p<0.001) as well as bad financial situation (aOR 1.60, 95% CI 1.02 to 2.48; p=0.04) were significantly associated with the higher risk of secondhand smoke exposure in cars. Out of all respondents, 84.2% supported the implementation of the ban on smoking in cars with children. Out of 12 different sociodemographic factors, only the female gender (aOR 1.94, 95% CI 1.37 to 2.74) and being non-smokers (aOR 1.70. 95% CI 1.20 to 2.41; p=0.003) were significantly associated with the higher odds of supporting the implementation of the ban on smoking in cars with children.

CONCLUSIONS

This study showed high public support for the implementation of the ban on smoking in cars with children. Social support for smoke-free environments in Poland should be used by public health specialists and policy-makers to strengthen the national tobacco control act.

Smoking behaviour and passive smoke exposure of adults - Results from GEDA 2019/2020-EHIS

Background

Smoking is a significant health risk and the leading cause of premature death. Passive smoke causes the same negative effects on health as smoking, albeit to a lesser extent. The reduction of tobacco consumption and the protection against passive smoke are thus important health objectives.

Methods

The study German Health Update (GEDA 2019/2020-EHIS) is a cross-sectional telephone survey (04/2019 to 09/2020) of the resident population in Germany with questions relating to the current smoking behaviour and relating to the passive smoke exposure. The analysis sample comprises 22,708 persons from 18 years of age.

Results

24.0% of women and 33.9% of men from 18 years of age smoke currently, at least occasionally. Among both sexes, adults from 65 years of age smoke significantly more rarely than adults in the younger age groups. 4.1% of adults, who do not smoke themselves, are subjected daily to passive smoke exposure indoors. This affects in particular young adults and men. There are educational differences in tobacco consumption and in passive smoke exposure to the disadvantage of adults from lower educational groups.

Conclusions

In Germany, there is still a need for action for effective measures for tobacco prevention, smoking cessation and tobacco control policy, which are effective in all population groups and which take into account the concerns of socially disadvantaged groups.
