Second-Hand Smoking among Intermediate and Secondary School Students in Madinah, Saudi Arabia

Association Between Second-Hand Smoke Exposure and Respiratory Symptoms Among the General Population of Non-smoker Adults in Saudi Arabia: A Cross-Sectional Study

BACKGROUND

Second-hand smoke (SHS) exposure is associated with respiratory symptoms such as cough, dyspnea, and wheezing. However, data on this association in Saudi Arabia is limited.

OBJECTIVES

The objective of this study is to investigate the prevalence of SHS exposure and its association with respiratory symptoms among non-smoker adults in Saudi Arabia.

METHODS

Data collection was carried out over the course of two months by distributing an online questionnaire among adults living in Saudi Arabia. The survey consisted of questions assessing sociodemographic factors, SHS exposure, and the presence of respiratory symptoms. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 22 (Released 2013; IBM Corp., Armonk, New York, United States). Data was considered significant if p<0.05.

RESULTS

The questionnaire was completed by 1360 participants. Most were females (n=845, 72.1%) and individuals aged 18 to 30 years (n=838, 71.5%). From the analyzed records, 67.3% (n=789) reported SHS exposure. Among them, 40.3% (n=472) reported SHS exposure from household sources, 32.6% (n=382) from work colleagues, and 30.5% (n=357) from friends. The majority (n=306, 76.9%) of those exposed at home reported daily SHS exposure. The main source of home exposure was male family members, particularly the father (n=201, 42.6%). The majority (n=985, 84.0%) of participants reported not having any kind of mold or damage at their place of residence. Individuals with SHS exposure were more likely to report asthma (p=0.043), chest whistling or wheezing (p=0.021), chronic cough (p<0.001), productive cough (p<0.001), and nasal symptoms without a cold (p<0.001). These individuals also demonstrated a higher average symptom score than those not exposed to SHS.  Conclusion: The study reveals that a significant percentage of the Saudi population is exposed to SHS daily, mainly from household sources, especially male family members. A significant association was found between SHS exposure and the presence of respiratory symptoms. Public awareness regarding the prevalence and dangers of SHS exposure is essential in order to alleviate the impact of SHS on the health of the general Saudi population. Additionally, further research is required in this field and demographic group to develop appropriate interventions.

Factors Related to Adolescent Smoking: A Nationally Representative Cross-Sectional Study in Thailand

Objective: This study aimed to explore the individual, familial, and social factors associated with different smoking status in Thai adolescents from the 2017 Cigarette Smoking and Alcohol Drinking Behavior Survey (CSAD) Methods: The nationally representative sample of 6046 adolescents aged 15-19 years who took part in the 2017 CSAD in Thailand. Multinomial logistic regression analysis was conducted to explore the associations between the individual, familial, and social factors and different smoking status.   Results: The daily smoking and occasional smoking was 6.4% and 3.3%, respectively. Gender, alcohol use, substance use, attitudes toward smoking, exposure to secondhand smoke at home, anti-smoking social media campaign, and graphic warning labels were related to both daily and occasional smoking. Daily smoking was associated with exposure to secondhand smoke at school, restaurant, and public transport, and exposure to tobacco advertising. Conclusion: These findings suggest that smoking prevention intervention should particularly focus on these factors and also need to develop the anti-smoking policies for smoking prevention among adolescents.

Prevalence and factors related to secondhand smoke exposure among secondary school-going adolescents in Malaysia: Findings from Malaysia Global Health School Survey 2012 and 2017

INTRODUCTION

Secondhand (SHS) smoke exposure has caused various health problems. Therefore, continuous monitoring of SHS exposure is important to determine the efficacy of various anti-tobacco measure implemented. The study aims to compare the prevalence and factor(s) associated with SHS exposure among secondary school-going adolescents in Malaysia during 2012 and 2017.

METHODS

We derived data from the Global School Health Survey (GSHS) 2012 and GSHS 2017, which was carried out in Malaysia using multistage sampling to select representative samples of secondary school-going adolescents. Both surveys used similar questionnaires to measure SHS exposure. Descriptive and multivariate logistic regression was used to determine the prevalence and factors associated with SHS exposure.

RESULTS

Approximately four in ten respondents were exposed to SHS in the past week in both surveys (41.5% in GSHS 2012 and 42.0% in GSHS 2017, respectively). Both surveys revealed a significantly higher SHS exposure among respondents who smoked than among non-smokers and higher among males compared to females. The likelihood of SHS exposure in both surveys was also similar, with a higher likelihood of SHS exposure among smoking adolescents and non-smoking adolescents who had at least one smoking parent/guardian, regardless of their own smoking status. Male adolescents had a higher risk of SHS exposure compared to their female counterparts. Meanwhile, SHS risk also increased with age, regardless of smoking status.

CONCLUSIONS

Our findings suggested that there were no changes in the prevalence of SHS exposure and recorded only a slight change in the factors associated with exposure to SHS among school-going adolescents in Malaysia between the years 2012 and 2017. A more pro-active, extensive and comprehensive programme should be implemented to address the problem of SHS exposure. Parents should be advised to stop smoking or abstain from smoking in the presence of their children, and smoking cessation interventions are necessary for smoking adolescents and their parents.

Exposure to secondhand smoke among school-going adolescents in Malaysia: Findings from the tobacco and e-cigarettes survey among Malaysian adolescents (TECMA)

INTRODUCTION

Many studies have revealed that exposure to secondhand smoke (SHS) substantially increases the risk of smoking related diseases especially among the vulnerable groups, yet data on the location of SHS exposure among youth in Malaysia are still lacking. The study aims to describe the prevalence and factors associated with SHS exposure at home, outside the home, and inside the school among school-going adolescents in Malaysia.

METHODS

We derived the data from the TECMA study, which used a cross-sectional study design and multi-stage sampling method to obtain a representative sample of school-going adolescents aged 11-19 years in Malaysia in 2016. Data were collected through a self-administered approach using a pre-validated standard questionnaire. Descriptive and multivariate analyses were used to analyze the data, and results are presented as adjusted odds ratio (AOR) with 95% confidence interval (95% CI).

RESULTS

SHS exposure for the past seven days was higher outside the home (51.2%; 95% CI: 49.2-53.2) compared to at home (37.8%; 95% CI: 35.8-39.9) while 27.3% (95% CI: 25.1-29.5) of school-going adolescents reported exposure to SHS inside the school in the past one month. In the regression analyses, older adolescents, those of Malay and Bumiputra Sarawak ethnicities, adolescents from rural areas and current smokers had higher likelihood of exposure to SHS at home, outside home and inside the school. Our study also found that adolescents who were current smokers had higher odds of being exposed to SHS at home (AOR=2.87; 95% CI: 2.57-3.21), outside the home (AOR=3.46; 95% CI: 3.05-3.92) and in the school (AOR=2.25; 95% CI: 2.01-2.51).

CONCLUSIONS

Health promotion measures should target parents/guardians and household members to reduce SHS exposure among adolescents. In addition, smoke-free regulation should be fully enforced in school. Furthermore, more public places should be designated non-smoking areas to reduce SHS exposure and denormalize smoking behavior.

Levels and factors of knowledge about the related health risks of exposure to secondhand smoke among medical students: A cross-sectional study in Jeddah, Saudi Arabia

INTRODUCTION

Secondhand smoke (SHS) appears to be an insidious public health issue in Saudi Arabia, with a high percentage of people being reportedly exposed. In an attempt to raise awareness about this issue, we explored medical students' level of knowledge about SHS risks, as well as their levels of exposure to SHS and the correlation between knowledge and exposure.

METHODS

A cross-sectional study was conducted in February 2020 at the Faculty of Medicine, King Abdulaziz University, Jeddah, Saudi Arabia. An online, modified version of a validated questionnaire was distributed among 2nd to 6th year medical students. The questionnaire mainly explored the following items: 1) exposure level to SHS; 2) impact of SHS exposure; and 3) knowledge about SHS related health risks, with calculation of a knowledge score (range: 0-8). Adequate knowledge was defined as a score ≥5 (median = 5), and associations with sociodemographic and lifestyle factors and exposure to SHS were analyzed using chi-squared and independent t-test, as appropriate.

RESULTS

Of a total 416 participants, 65.0% declared having one or more smoking persons among acquaintances, 26.4% being exposed to SHS at home, and 40.1% exposed to parental smoking during childhood. Further, 79.8% reported being regularly exposed to SHS in public places. Majority of participants reported significant discomfort (53.2%) and physical symptoms (98.3%) subsequent to SHS exposure. Among the list of 8 health risks, ear infection in children (28.1%), heart attack in children (37.5%), and cognitive deficit (47.8%) were the least frequently identified. Adequate knowledge was found among 57.5% of the participants, and was higher among females and lower among participants living with their friends, compared to their counterparts (p<0.05). No association of knowledge level was observed with the parameters of exposure to SHS and poor discomfort feeling.

CONCLUSIONS

The level of knowledge of medical students about health risks related to passive smoking is inadequate, while their exposure to SHS in public places is still substantial. This urges for the reinforcement of tobacco control strategies and highlights the great interest for medical colleges to implement effective educational interventions by improving their curricula regarding the risks of SHS and the benefits of smoking cessation.

Exposure to household secondhand smoke among adolescents in Kuwait: Results from two school-based cross-sectional studies

INTRODUCTION

Detrimental effects of secondhand smoke (SHS) exposure are well established; however, data on SHS exposure among adolescents in Kuwait are lacking. Hence, this study sought to estimate the prevalence of household SHS exposure among two samples of adolescents in Kuwait and assess its variation by socioeconomic status and parental education level.

METHODS

Data from two large school-based cross-sectional studies were analyzed. Adolescents attending public middle (n=3864; aged 11–14 years) and high (n=1959; aged 14–19 years) schools throughout Kuwait were enrolled in 2016-2017, and parental self-reported household SHS exposure was ascertained. Associations were assessed using Poisson regression with robust variance estimation, and adjusted prevalence ratios (APRs) and 95% confidence intervals (CIs) were estimated.

RESULTS

Overall, 45.8% (1755/3836; 95% CI: 44.2–47.3%) of the enrolled middle school students and 51.6% (998/1936; 95% CI: 49.3–53.8%) of the enrolled high school students were exposed to household SHS. Among middle and high school students, the prevalence of household SHS exposure increased as maternal/paternal education level and family income decreased. Among middle school students, paternal educational attainment of middle school or less compared to bachelor’s degree or higher was associated with 1.60 times (95% CI: 1.44–1.79) higher household SHS exposure. Similarly, in the sample of middle school students, the prevalence of household SHS exposure significantly increased from 35.8% among children from families reporting the highest household income to 50.5% among children from families with the lowest reported household income (p-trend<0.001).

CONCLUSIONS

Household SHS exposure is substantially high among adolescents in Kuwait. Enrolled adolescents from families with low socioeconomic status or with low parental education level have the highest household SHS exposure. These findings highlight the need for national comprehensive tobacco control policies and increasing parental awareness of the impact of SHS exposure on children.

A systematic review of the prevalence and risk factors of smoking among Saudi adolescents

OBJECTIVES

To systemically review the evidence concerning the prevalence and reported risk factors of smoking among adolescents in Saudi Arabia. Methods: Following the PRISMA guidelines, studies that examined the prevalence and risk factors of smoking among adolescents in Saudi Arabia were identified through a computerized literature search using the following databases up to March 2018: PubMed, SCOPUS, Web of Science, and BIOSIS. The following search terms were used: smoking OR smok* OR tobacco OR cigar* OR shisha OR shesha OR sheesha AND Saudi Arabia OR KSA. Peer-reviewed articles published within the period from 2007 to 2018 were selected. Studies that reported prevalence data, patterns, and risk factors of smoking among adolescents were included. Extracted data from each study were tabulated, and data were narratively synthesized.

RESULTS

Thirty-two studies that reported the prevalence of smoking in the adolescent age group were included in the narrative evidence synthesis. These studies were conducted on secondary school students (n=11), college students (n=14), and an adolescent age group without educational specifications (n=7). According to published reports between 2007 and 2018, the prevalence of tobacco smoking among adolescents in Saudi Arabia ranged from 2.4% to 39.6%. Influence of friends, and family negligence were the most commonly reported risk factors for smoking. Conclusion: The prevalence of smoking is relatively high among adolescents in Saudi Arabia. The social influence of friends, teachers or parents, low academic performance, having spare time, living away from home, and the desire to relieve stress were the most commonly reported risk factors for smoking.

Tobacco use among adolescents in Qatar: Findings from Global Youth Tobacco Surveys 2004-2013

INTRODUCTION

Tobacco use has become a global health concern. Almost a third of the adolescents of the Eastern Mediterranean Region (EMR) have reported tobacco use and the percentage is expected to rise in the future, making tobacco consumption a main public health issue among students, 13–15 years old, in the region’s countries. We aimed to conduct an analysis of the previous Global Youth Tobacco Surveys (GYTS) in Qatar to detect any significant changes that might inform decision makers on planning policies and interventions accordingly.

METHODS

This study presents a retrospective data analysis, based on three GYTS conducted in Qatar during 2004, 2007, and 2013. All analyses were weighted to account for the complex survey design and for differential non-response at school, class and student levels, with the exception of the analysis of sociodemographic characteristics. The differences between the proportions were tested by Pearson’s chi-squared test. Data were analyzed using the statistical software SPSS (Statistical Package for Social Sciences), version 21.0 (Chicago, IL). A p-value <0.05 was considered to be significant.

RESULTS

There was an overall increase in the prevalence of smoking, the accessibility, and the availability of cigarettes. Additionally, the percentage of participants who desired to stop smoking decreased between 2004 and 2013, while that of students who reported ‘exposure to free tobacco promotion’ was highest in 2013.

CONCLUSIONS

Despite the effort made by the local authorities in Qatar to reverse the spread or limit the growing tobacco epidemic, there is a need for multidisciplinary interventions through tobacco prevention and control programs targeting youths.

Student, school, parent connectedness, and school risk behaviors of adolescents in Saudi Arabia

Background and Objectives

School-related risk behaviours, such as school absenteeism, and engaging in violence on school property are scarcely addressed in the Kingdom. The study investigated select school behaviours, including school absenteeism, engaging in fights, and discipline for misconduct at school as well as their association with the school environment, school and home connectedness.

Design and setting

A school-based cross-sectional study.

Materials and methods

A total of 1668 students were selected from high schools in Riyadh on the basis of geographical location (North, South, Middle) and type of school. In each geographical area, the two largest public schools, one private school and one international school were selected. Classrooms with a free period were selected at random, and all of the students in select classrooms were eligible to participate in the study. The study employed a self-administered survey that inquired about school behaviours and student connectedness with their parents and school.

Results

Nearly 54% of students skipped school or cut classes for at least 1 h, and out of those students who skipped school, 37% of students skipped school for 1-3 h and 20% of students skipped school for 3 or more hours during the month prior to the survey. Thirty-eight percent of students engaged in fights on school property at least once during the past or current academic year. In addition, 37% of students were disciplined for engaging in school fights, theft or damaging school property at least once.Absenteeism increased with grade, while engaging in school fights and discipline for misconduct decreased with grade. A significantly higher proportion of males exhibited these behaviors, and students who exhibited these behaviors reported significantly lower levels of school connectedness and parental monitoring. Regression analyses suggested that school-student connectedness reduced the odds for all three risk behaviors examined in this study. Parental monitoring reduced the odds for absenteeism, and school policies reduced student involvement in school fights.

Conclusion

This study highlights the need to develop strategies to enhance the best practices in school settings to promote positive student behavior and school achievement. Schools and parents should be encouraged to work as a team and to recognize the importance of school connectedness in improving positive student behavior and outcomes.
