Rising trends in the burden of cardiovascular comorbidities and major adverse cardiovascular events among young female smokers in two national cohorts studied ten years apart (2017 vs. 2007)

BackgroundAmple evidence suggests that female smokers face a greater risk of smoking-related health problems than male smokers. Due to the growing number of young smokers in the United States, there has been limited information on the effects of smoking on young female smokers over the past decade. MethodsHospitalizations of young (18-44 years) female tobacco smokers were identified using the National Inpatient Sample datasets from 2007 and 2017. We compared differences in admission frequency, comorbidity burden, in-hospital outcomes [all-cause mortality and major adverse cardiac events (MACE)], and resource utilization between two young cohorts separated by 10 years. ResultsIn 2007, there were 665,901 admissions among young female smokers (median age: 35), compared to 1,224,479 admissions (median age: 32) in 2017. In both cohorts, white female smokers accounted for most admissions, followed by blacks. In 2017, the prevalence of alcohol abuse, hyperlipidemia, uncomplicated diabetes, and chronic pulmonary disease decreased relative to the 2007 cohort, whereas the prevalence of deficiency and chronic blood loss anemias, diabetes with complications, drug abuse, hypertension, congestive heart failure, depression, liver disease, and obesity increased significantly (p<0.001). The 2017 cohort had significantly higher odds of all-cause mortality [aOR 1.25 (95%CI: 1.16-1.35)] and a higher risk of MACE [aOR 1.17 (95%CI:1.14-1.20)] upon multivariable adjustment. (p<0.001). Comparatively, the 2017 cohort had fewer routine discharges and higher home healthcare needs than the 2007 cohort. ConclusionsIn this decade-apart analysis, the study reveals rising trends in the burden of comorbidities, MACE, and healthcare resource utilization in admissions (regardless of the primary cause) among relatively younger female smokers. It is crucial to educate young female smokers about the detrimental effects of tobacco and polysubstance abuse on cardiovascular outcomes.

Abstract 10416: Rising Trends in the Burden of Cardiovascular Comorbidities and Major Adverse Cardiovascular Events in Young Female Smokers Across Two Nationwide Cohorts Studied a Decade Apart (2017 vs. 2007)

Background: Ample evidence has suggested that female smokers are at a higher risk of smoking-related health problems compared to men. With the increasing number of young smokers in the US, there is limited data on the impact of smoking in young female smokers in the last decade. Methods: The National Inpatient Sample datasets (2007 and 2017) were utilized to identify hospitalizations among young (18-44 years) female tobacco smokers. We compared differences in frequency of admissions, comorbidity burden, and in-hospital outcomes (all-cause mortality and MACE) and resource utilization across two young cohorts 10-years apart. Results: A total of 1,224,479 (median age 32) admissions among young female smokers were identified in 2017 vs. 665,901 (median age 35) in 2007. Both cohorts showed the majority of admissions among white female smokers, followed by African Americans (Table 1) . Compared to the 2007 cohort, the rate of alcohol abuse, hyperlipidemia, uncomplicated diabetes and chronic pulmonary disease decreased inn 2017, whereas a rising trend was observed for deficiency and chronic blood loss anemias, diabetes with complications, drug abuse, hypertension, congestive heart failure, depression, liver disease, and obesity (p&lt;0.001). On adjusted multivariable analysis, the 2017 cohort showed significantly higher odds of all-cause mortality [aOR 1.25 (95%CI: 1.16-1.35)] with a higher risk of MACE [aOR 1.17 (95%CI:1.14-1.20)] (p&lt;0.001). There were fewer routine discharges and higher requirements of home health care in the 2017 cohort vs. 2007. Conclusion: The study reveals escalating trends in the burden of comorbidities, MACE and healthcare resource utilization in admissions (irrespective of primary cause) among young female smokers in this decade apart analysis. It is essential to raise awareness among young female smokers about the adverse impact of tobacco and associated polysubstance abuse on cardiovascular outcomes.

Latent class analysis of initial nicotine dependence among adult waterpipe smokers.

Waterpipe (WP) tobacco smoking increases the risk of smoking-related health problems. In this study, we sought to identify the unobserved class memberships of WP-associated initial nicotine dependence (ND) symptoms and assess the predictors of each latent class. This cross-sectional study was conducted among a convenience sample of 900 current (past 30-day) WP smokers who were recruited from 94 WP-serving venues surrounding Tehran and Ardebil metropolitans in Iran. All participants completed a self-administrated questionnaire. We performed latent class analysis using PROC LCA in SAS to identify class memberships of initial ND symptoms using 10-item Hooked on Nicotine Checklist. Five latent classes were identified as non-dependent (25.4 %), low dependent (7.1 %), low-moderate dependent (19.6 %), moderate dependent (15.6 %), and high dependent (32.2 %). Using flavored WP tobacco significantly increased the odds of belonging to low-moderate dependent class [adjusted OR (aOR) = 1.89; 95 % confidence interval (CI): 1.07-3.34] compared to non-dependent class. Also, having academic education decreased the odds of belonging to low-moderate dependent (aOR = 0.43; 95%CI: 0.26-0.67) and moderate dependent (aOR = 0.39; 95%CI: 0.23-0.67) class in comparison to non-dependent class. Also, WP smoking initiation at an older age was associated with belonging to high dependent (OR = 2.05; 95%CI: 1.39-3.03) class compared to non-dependent. This study revealed that nearly half of WP smokers fell under moderate and high-dependent classes. Our findings showed that some items of HONC had more role in the clustering of participants based on ND symptoms. The WP-specific cessation programs and targeted clinical trials should consider the diversity of ND levels among smokers to achieve successful quit rates among these smokers. Additionally, limiting flavors would be a strong strategy to limit the rate of ND, especially among young people who are eager to smoke flavored WP tobacco.

Relationship of trauma exposure and PTSD to cigarette smoking prevalence, frequency, and quantity: Data from a nationally representative sample of U.S. adults.

To examine differences in cigarette smoking behaviors among adults in the United States (a) with no exposure to trauma or PTSD, (b) with trauma but no PTSD, and (c) with PTSD. Data came from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions-II (NESARC-II, 2004-2005) and included demographics, PTSD diagnoses, traumatic events, and smoking behaviors. Odds ratios and group differences in smoking prevalence and behaviors based on PTSD diagnoses and exposure to traumatic experiences were calculated. Traumatic events and PTSD diagnoses were both associated with greater smoking prevalences than persons without trauma or PTSD. Individuals with PTSD who smoke were more likely to report daily smoking than those without PTSD who smoke (Cohen's d = 0.19). Cigarette users with either trauma or PTSD smoked more cigarettes per day than cigarette users without trauma or PTSD (Cohen's d = 0.35). US adults with trauma exposure or PTSD have higher smoking prevalences and more intense smoking behaviors than those without PTSD or trauma. Trauma or PTSD may each serve as a clinical indicator of increased risk of cigarette smoking-related health problems and prompt the implementation of targeted interventions to reduce the harms of smoking.

Associations of tobacco retailer availability with chronic obstructive pulmonary disease related hospital outcomes, United States, 2014.

There are associations between tobacco retailer density and smoking behaviors, but little is known about whether places with more tobacco retailers have more smoking-related health problems. Using cross-sectional data from 2014, we investigated the relationships between tobacco retailer density and chronic obstructive pulmonary disease (COPD) related outcomes in a sample of 1510 counties across the United States. Higher retailer density was associated with a 19% (IRR, 1.19; 95% CI, 1.12-1.27) higher COPD-related hospital discharge rate and 30% (IRR, 1.30; 95% CI 1.21-1.39) higher total COPD-related hospital costs per population. The tobacco retailer environment may be an important target for reducing smoking-related health burdens and costs.

Comparing cigarette smoking knowledge and attitudes among smokers and non-smokers.

Smoking prevalence in Lebanon was reported by the World Health Organization to be 43%, which is among the highest rates in the Arab nation. The objectives of this study were to assess cigarette smoking knowledge and attitude among smokers and non-smokers using validated scales in the Lebanese general population and evaluate their association with current cigarette smoking; a secondary objective is to assess the dose effect relationship of knowledge and attitude with cumulative smoking. This cross-sectional took place between May and December 2018, and enrolled a sample of 2623 participants, representative from all Lebanese governorates. A questionnaire about knowledge of the harmful effects of tobacco and attitude toward smoking bans retrieved from other studies was used to collect data. Male gender (ORa = 0.75), having a low monthly income (ORa = 1.56) and a higher passive smoking score (ORa = 1.25), were significantly associated with higher odds of being current smokers. Higher knowledge score (ORa = 0.97) and positive attitude toward smoking ban score (ORa = 0.94) were significantly associated with lower odds of being current smokers. In addition, increased age (ß = 15.21) and higher passive smoking score (ß = 26.58) were significantly associated with higher cumulative cigarette smoking. More positive attitude toward smoking ban score (ß = - 6.51) and having a university degree (ß = - 68.35) were significantly associated with lower cumulative cigarette smoking. Higher knowledge about the smoking-related health problems and better attitudes toward smoking ban were observed among non-smokers compared to smokers. It is important to increase awareness campaigns and to propose effective interventions to put in place an adequate culture of smoking cessation among the general population.

Prevalence of Smoking among Medical Students in Kathmandu, Nepal

Smoking is a leading risk factor for early death and disability worldwide. Medical students and physicians are the ideal persons to educate patients about hazards of smoking. Today’s medical students will play a prominent role in future to prevent and control tobacco use. Still, the problem of smoking among the medical students is common worldwide but the pattern and extent of the problem varies from place to place. Aim of this study was to find out prevalence of smoking among medical students, factors contributing to their smoking habits, their exposure to passive smoking and to know about their knowledge about smoking related health problems. This is a cross sectional study, conducted among all first and second year MBBS students during July-September 2018. Self administered questionnaire were given to all the participants and collected after it was filled up. One hundred seventy four students participated in the study. Prevalence of smoking was 5.2% and all the students who smoked were male. The most important cause for initiation of smoking was peer pressure (56%). The average cigarettes smoked was seven sticks per day. Though 80% students knew about hazards of passive smoking, almost half of them were exposed to passive smoking. In our study we found that most of the students do not counsel their patients regarding hazards of smoking and only few participants were found to advise and encourage their patients to quit smoking.

A systematic review of anxiety across smoking stages in adolescents and young adults

Background: In adolescence and young adults, inconsistence of the association between anxiety and smoking remains to be investigated and clarified. The aim of this study is investigated and clarified the association between anxiety and smoking stages in adolescence and young adults. Methods: The data on the causal influence of anxiety on smoking in adolescents and young adults aged 14 to 25 years old was retrieved from electronic databases. Results: Nineteen of 668 articles were subjected to a systematic review. Definitional differences with respect to smoking stages constrained homogeneity across the nineteen analyzed reports. Anxiety appears to play a more consistent risk role for nicotine dependent (ND) smokers than for non-nicotine dependent (non-ND) regular or daily smokers. Anxious non-ND smokers are at higher risk to become nicotine dependent. Conclusions: A ununified definition of smoking stages is responsible for the production of inconsistent results. The analysis reinforced anxiety as a significant risk factor for smoking in one’s lifetime. Anxious non-ND smokers are the key target for interventions aimed at preventing nicotine dependence and smoking-related health problems.

Курение матери и нарушения метилирования ДНК у детей на ранних стадиях развития

The paper analyzes the results of current studies of the role of DNA methylation during human embryonic development and the effects of tobacco smoke from maternal smoking on the epigenetic status of a developing child. The molecular mechanisms mediating the association between maternal smoking and its effects on the development and health of the offspring, especially its long-term effects that manifest throughout his/her life are the object of active research in medicine and biology. Human genomics studies in recent years have shown that one of these mechanisms may be the epigenetic regulation of gene activity, namely, stable tobacco smoke-induced alterations in this system can cause concomitant smoking-related developmental and health problems. Active smoking is an important risk factor for morbidity and premature mortality, while maternal smoking during pregnancy has a double effect: firstly, it adversely affects women’s health and secondly, it leads to irreparable fetal developmental disorders and affects the health and development of the newborn and the quality of his/her subsequent life.

Sociodemographic predictors of tobacco smoking among expatriate and national adolescents in the United Arab Emirates.

Tobacco use among adolescents is an important public health concern as it causes various forms of smokingrelated health problems and can create a gateway for other substance abuse. This study examined the prevalence, profile and predictors of tobacco use among expatriate and national adolescents living in the United Arab Emirates (UAE). Using a cross-sectional study design (2007-2009), we collected data on the prevalence of tobacco use in 6363 adolescents aged 13-20 years, including current smokers of cigarettes, midwakh, shisha and any other form of tobacco. We also collected demographic, socioeconomic, residential and behavioural data. In the previous 30 days, 505 (8.9%) participants had smoked cigarettes, 355 (6.3%) had smoked midwakh, 421 (7.4%) had smoked shisha and 380 (6.4%) had smoked any other form of tobacco. Overall, 818 (14.0%) adolescents were current smokers, who reported occasional or daily use of at least one form of tobacco in the past 30 days. Results consistently indicated that the prevalence of tobacco use was higher among men than women, regardless of age and tobacco form. Among men, cigarette smoking was the most popular, whereas shisha was the most smoked form of tobacco among women. Being male and ever having used illegal drugs consistently emerged as significant predictors of all forms of tobacco use. There is a need for continued public health strategies and education campaigns to discourage adolescents in the UAE from using tobacco.

Non-invasive sensor based automated smoking activity detection.

Although smoking prevalence is declining in many countries, smoking related health problems still leads the preventable causes of death in the world. Several smoking intervention mechanisms have been introduced to help smoking cessation. However, these methods are inefficient since they lack in providing real time personalized intervention messages to the smoking addicted users. To address this challenge, the first step is to build an automated smoking behavior detection system. In this study, we propose an accelerometer sensor based non-invasive and automated framework for smoking behavior detection. We built a prototype device to collect data from several participants performing smoking and other five confounding activities. We used three different classifiers to compare activity detection performance using the extracted features from accelerometer data. Our evaluation demonstrates that the proposed approach is able to classify smoking activity among the confounding activities with high accuracy. The proposed system shows the potential for developing a real time automated smoking activity detection and intervention framework.

AN EVALUATION OF THE EFFECTS OF COMBINED HEALTH WARNINGS ON CIGARETTE PACKETS THROUGH EYE MOVEMENTS

Smoking is the source of fundamental health problems. Activities have been organised throughout the world so that smokers and non-smokers do not encounter smoking-related health problems in society. One such activity is the combined health warnings designed to be printed on cigarette packets. The warnings on cigarette packets are considered as an instrument of education to develop the desired attitudes in individuals by improving their knowledge of health. This research aims to evaluate the effects of 14 combined health warnings printed on cigarette packets on smokers and non-smokers. This is a descriptive research, and it employs a correlation model. The research group was composed of 57 individuals participating in the research on the basis of volunteering. The data were collected through eye-tracking and by means of two forms. According to the findings, the combined warnings on cigarette packets were moderately influential and they were remembered at low levels. It was also found that the participants were familiar with the combined warnings on cigarette packets and that they avoided the warnings. These results demonstrate that the warnings should be re-evaluated by taking diverse demographic properties into consideration. Key words: cigarette packet, combined health warnings, eye movements, university student, health education.

How Tobacco Companies are Perceived Within the United Kingdom: An Online Panel.

Little is known about how consumers perceive tobacco companies in the United Kingdom. An online cross-sectional survey with those aged 16 years and over (N = 2253) explored perceptions of, and attitudes towards, tobacco companies. This included awareness of tobacco companies, views on tobacco companies' practices (targeting the most vulnerable, encouraging smoking to replace those who quit or die, making cigarettes more addictive) and values (honesty, ethics, interest in harm reduction), perceptions of regulation of tobacco companies (whether tobacco companies have the same marketing rights as other companies, should be allowed to promote cigarettes, be required to sell cigarettes in plain packs, and pay for associated health costs), and locus of responsibility for health problems caused by tobacco use. Prompted awareness of tobacco companies was high (68%). Almost a third of the sample had a negative perception of tobacco companies' practices, for example, they thought they made cigarettes more addictive. In terms of tobacco companies' values, less than a fifth considered tobacco companies honest, ethical, and interested in reducing the harm caused by cigarettes. Indeed, tobacco company executives were rated lower than the seven other professions asked about, except car salesman, in terms of ethics and honesty. More than half the sample supported greater regulation, for example, requiring tobacco companies to pay for health costs due to tobacco use. Most attributed responsibility for smoking-related health problems to smokers (88%) and tobacco companies (55%). The findings suggest that consumers are not fully informed about tobacco company practices. Few studies outside of North America have explored perceptions of tobacco companies' practices, values and regulation and responsibility for smoking-related illness. Adults surveyed within the United Kingdom considered tobacco companies dishonest, unethical and untrustworthy, but only a third of the sample thought that they encourage new smokers or have made cigarettes more addictive, and just over a half attributed most of the responsibility for smoking-related health problems to tobacco companies. As consumers do not appear fully informed about the role of tobacco companies in initiating and perpetuating the tobacco epidemic, tobacco industry denormalization campaigns may be of potential value.

Parental perceptions towards passive smoking: a cross-sectional survey in Vikarabad town, India

Background : Environmental tobacco smoke is a known human carcinogen and passive smoking has now emerged as a health threat. Home is the major source of exposure to tobacco smoke among children. Objective : To explore parents’ smoking behaviour and their perceptions towards passive smoking and its effects on their children. Method : A cross-sectional, household survey was conducted on 179 smoking parents in an Indian town using a semi-structured questionnaire which gathered information about demographic factors and 21 questions assessing their smoking behaviour and perceptions about passive smoking. Results : Thirty two percent reported that they did not know smoking caused cancer and only 25% strongly believed that if parents smoked, it had a harmful effect on children's health. Conclusion : Low education, unskilled jobs and a past experience of smoking related health problems have an influence on the way passive smoke and its harmful effects are perceived by smoking parents.

Generation shifts in smoking over 20 years in two Dutch population-based cohorts aged 20-100 years.

BackgroundYounger and older generations may differ substantially in their lifetime smoking habits, which may result in generation-specific health challenges. We aimed to quantify generation shifts in smoking over a period of 25 years.MethodsWe used the Doetinchem Cohort Study (baseline 1987–1991; 7768 individuals; 20–60 years; follow-up 1993–2012) and the Longitudinal Aging Study Amsterdam (baseline 1992–1993; 3017 individuals; 55–85 years; follow-up 1995–2009). Generation shifts were studied between 10-year generations (age range: 20–100 years). Generation shifts were examined graphically and by using logistic random effect models for men and women.ResultsAmong men, significant generation shifts in current smoking were found between two non-successive generations: for instance men in their 40s at baseline smoked much more than men in their 40s at follow-up (33.6% vs. 23.1%, p < 0.05). Among women, the most recently born generation showed a favourable significant generation shift in current smoking (−7.3%) and ever smoking (−10.1%). For all other generations, the prevalence of ever smoking among women was significantly higher in every more recently born generation, whereas no other generation shifts were observed for current smoking. The unfavourable generation shifts were mainly found among the lower educated.ConclusionsThe future burden of disease due to smoking is expected to be reduced among men, but not yet among women. Educational differences in smoking-related health problems are expected to increase.

Correlates of current smoking among Malaysian secondary school children.

Cigarette smoking in adolescent is a significant public health problem, leading to the risk of addiction, morbidity, and mortality in the long term. This study determined the prevalence and correlates of current smoking among adolescent school children. A nationwide school-based survey among 25 507 students between Forms 1 to 5 (aged 12-17) was conducted using a 2-stage cluster sampling design. The prevalence of current smoking was 11.5%. Multivariable logistic regression analysis revealed that current smoking was significantly associated with males (adjusted odds ratio [aOR] = 3.25; 95% confidence interval [CI] = 1.87, 4.98), current drinking (aOR = 2.34; 95% CI = 1.46, 3.74), drug used (aOR = 2.97; 95% CI = 1.24, 7.11), and being bullied (aOR = 1.41; 95% CI = 1.00, 1.98) at least once in the past 12 months. Smoking is associated with several behaviors that pose risks to adolescents, such as social issues and smoking-related health problems. Thus, early and integrated prevention programs that address multiple risk behaviors simultaneously are required.

Report Links Smoking to Poor Cancer Outcomes

A comprehensive new report on smoking and cancer, released on the 50th anniversary of the Surgeon General's first such report, highlights successes of the resulting anti-tobacco movement and expands the long list of smoking-related health problems. It also offers evidence documenting the harms of continued smoking for people with cancer.

Prevalence of smoking among secondary school male students in Jeddah, Saudi Arabia: a survey study

BackgroundThis study was conducted to examine the prevalence of smoking and the smoking habits among male secondary school students in Jeddah, Kingdom of Saudi Arabia and to assess their knowledge and attitudes towards smoking.MethodsA cross-sectional study was conducted in Jeddah, using a two-stage cluster sample that randomly selected four schools from 85 public secondary schools for males. Data were obtained through a self-administered questionnaire containing questions on personal background, smoking behavior, knowledge, and behavior and attitudes towards smoking. A total of 695 students responded to the questionnaires with an 87.4% response rate.ResultsThe age range of this student sample was 16–22 years. Two hundred fifty-eight (37%) of the study group were current smokers. The most common reasons given for smoking were personal choice (50.8%) and the peer pressure from smoker friends (32.8%). Many students researched the smoking hazards (68.1%), but only 47.6% knew about the bad effects of passive smoking. Two thirds of the smoking students wanted to quit smoking (63.2%), especially if suitable help was available, and 75.1% tried to quit. A third of the smoking students (36.8%) found it difficult to stop smoking in no-smoking areas.ConclusionA well-planned integrated antismoking campaign is urgently required, especially among students and teachers. Our study revealed that smoking prevalence was high, which will lead to future high smoking-related health problems if proper preventive measures are not taken accordingly.

Smokers’ Knowledge About Smoking-Related Health Problems in Lebanon

The relationship between smokers’ knowledge about smoking related health problems and the motivation to quit smoking in a sample of Lebanese smokers was evaluated. The first group of smokers was composed of hospitalized subjects for a cardiologic or a respiratory health problem (n = 42). The second group was composed of smokers who have not suffered from any smoking-related health problem (n = 69). A positive correlation was found between the Richmond test score and the knowledge level about smoking related health problems (r = .302; p = .0013).

Prevalence of smoking among male secondary school students in Jeddah, Saudi Arabia

Objectives:This study was conducted to examine the prevalence of smoking and habits of smoking among male secondary school students in Jeddah, Kingdom of Saudi Arabia (KSA) and to assess their knowledge and attitudes toward it.Materials and Methods:A cross-sectional study was conducted in Jeddah, using a two-stage cluster sampling, randomly selecting 4 out of 85 government male secondary schools. Data were obtained through a self-administered questionnaire eliciting responses to questions on personal background, smoking behavior, knowledge, behavior, and attitude toward smoking. A total of 695 students responded to the questionnaires with 87.4% response rate.Results:Of the studied group, 258 (37%) currently smoked, and of these, 83.7% had started smoking at the age of 14 years or less. The most common reason for smoking was the influence of family, especially the presence of someone at home who smoked (65, 9%) and friends who smoked (42.5%). Many of the students search for information on the risks of smoking (66.3%), and only (45.3%) knew about the bad effects of passive smoking on others. Two-third of the students who smoked wanted to quit smoking (63.2%), especially if suitable help was offered, whereas (60.9%) had tried to quit. While 50% of students smoked for recreation and entertainment, and (33.6%) had difficulty avoiding smoking in no smoking areas.Conclusion:A well-planned integrated antismoking campaign is urgently required, especially among students and teachers. The study revealed that the prevalence of smoking was high. This will contribute to an increase in smoking-related health problems in the future if proper preventive measures are not taken.
