Association of cigarette and water-pipe smoking with increased visceral adiposity, glycemic intolerance and hematological derangement in Iraqi healthy smokers

Abstract The present study aims to investigate the impacts of cigarette smoking (CS) and water-pipe smoking (WPS) on the visceral adiposity index (VAI), hematological characteristics, and glycemic tolerance in Iraqi healthy smokers. A total of 528 healthy males from different locations of Baghdad city were allocated to three groups; nonsmokers (176), cigarette smokers (178), and WP smokers (174). Baseline characteristics, anthropometric and hematological markers and were reported. Glycemic control was evaluated using the glucose tolerance test. The evidence of elevated VAI, disrupted hematological markers, and impaired glucose tolerance was significantly (P<0.001) different compared with non-smokers and related to the duration of smoking. The impacts of WPS seem to be significantly greater than CS in certain parameters (hemoglobin, hematocrit, methemoglobin, and 2-hour glucose tolerance values). In conclusion, CS and WPS negatively impacted body fat distribution, glucose tolerance, and hematological markers. There is a positive association between the rate of smoking and obesity, glycemic intolerance in both groups

Effect of heavy cigarette and water pipe smoking on antioxidants and lipids in Sudanese male smokers: a case-control study

Background: Tobacco smoking is a source of many toxins such as free radicals, mutagenic substances as well as cause for developing cardiovascular diseases (CVD), particularly atherosclerosis. This study aims to assess the impact of smoking on antioxidants in Sudanese male smokers. Methods: Cases were 85 and 48 men who smoke cigarettes (CS) and water pipe (WPS) respectively and they were compared with matching 50 non-smoking controls. Blood samples were collected and following parameters: Glutathione peroxidase, Superoxide dismutase, Total cholesterol, Triglyceride, LDL, HDL, Paraoxinase, and Malondialdehyde were measured. Results: There were no significant differences in biochemical parameters between light CS and WPS compared to controls. In heavy smokers of both WPS and CS, the TC, TG, LDL, and MDA were higher than controls (p>0.05), GPx, SOD, HDL, and PON were lower in smokers than controls (p>0.05). In both groups of smokers, HDL, GPx, SOD, and PON were inversely correlated with duration of smoking (p>0.05), also, HDL was positively correlated with SOD and GPx (p>0.05). Moreover, GPx and SOD were correlated with each other in both groups of smokers (p>0.05). Conclusion: In Sudanese male smokers' biochemical profile disturbances suggest that heavy smoking was leading to developing CVD, particularly WPS

Prevalence of electronic nicotine delivery systems and waterpipe use in Brazil: where are we going? / Prevalência de uso de dispositivos eletrônicos para fumar e de uso de narguilé no Brasil: para onde estamos caminhando?

ABSTRACT Objective To describe the prevalence of use of electronic nicotine delivery systems (ENDS) and waterpipe in Brazil, by population subgroups, and to evaluate the trend between 2013 and 2019. Methods We used data from the 2019 National Health Survey to estimate the prevalence of lifetime and current use of ENDS and current use of waterpipes by socio-behavioral characteristics. Differences in prevalence over time were calculated using data from the III Brazilian Household Survey on Substance Use-2015 and the National Health Survey-2013. Results For 2019, the prevalence of current use of ENDS was estimated at 0.64% (∼1 million people), of which ∼70% were in the age group of 15-24 years old. The highest prevalence was observed in the Midwest region, but the Southeast region concentrates half of these users. Almost 90% are non-smokers, with high prevalence among those who also use waterpipe and abuse alcohol. There was an increase in ENDS use between 2015 and 2019, particularly among younger people. The prevalence of current waterpipe use in 2019 was estimated at 0.47% (∼800,000 individuals), of which ∼80% were 15-24 years old. There was an increase in the prevalence of current waterpipe use between 2013 and 2019, and among young people the increase was ∼300%. Conclusions In Brazil, ENDS have been used mostly by young people, and by never smokers of manufactured cigarettes. The use of ENDS and waterpipe has been increasing even with the country's regulatory restrictions, which may compromise the successful history of the tobacco control policy.

RESUMO: Objetivo: Descrever as prevalências de uso de dispositivos eletrônicos para fumar e de narguilé no Brasil, por subgrupos populacionais, e avaliar tendências entre 2013 e 2019. Métodos: Os dados principais analisados são da Pesquisa Nacional de Saúde de 2019. Estimaram-se prevalências de uso na vida e atual de dispositivos eletrônicos para fumar e de uso atual de narguilé segundo características sociocomportamentais. Os dados da Pesquisa Nacional de Saúde-2019 sobre dispositivos eletrônicos para fumar foram comparados aos do III Levantamento Nacional sobre Uso de Drogas pela População Brasileira e os dados sobre narguilé comparados aos da Pesquisa Nacional de Saúde 2013. Resultados: Para 2019, estimou-se a prevalência de uso atual de dispositivos eletrônicos para fumar em 0,64% (∼1 milhão de pessoas), dos quais ∼70% tinham 15-24 anos. A maior prevalência está na região Centro-Oeste, mas o Sudeste concentra metade absoluta desses usuários. Quase 90% são não fumantes, e maiores prevalências foram encontradas entre quem usa também narguilé e álcool abusivo. Observou-se aumento nas estimativas de uso de dispositivos eletrônicos para fumar entre 2015 e 2019, especialmente entre os mais jovens. A prevalência de uso atual de narguilé em 2019 foi estimada em 0,47% (∼800 mil indivíduos), dos quais ∼80% tinham 15-24 anos. Houve aumento na prevalência de uso atual de narguilé entre 2013 e 2019, e entre jovens o aumento foi de ∼300%. Conclusões: No Brasil os dispositivos eletrônicos para fumar têm sido utilizados majoritariamente por jovens e por nunca fumantes de cigarros industrializados. O uso de dispositivos eletrônicos para fumar e de narguilé vem aumentando, mesmo com as restrições regulatórias do país, podendo comprometer o exitoso histórico da política de controle do tabagismo.

Fatores relacionados ao consumo do narguilé entre estudantes de medicina / Factors related to the use of hookah among medical students

RESUMO Objetivo Avaliar o nível de conhecimento sobre os malefícios do narguilé, a frequência e os fatores psicossociais envolvidos na sua utilização entre os estudantes de Medicina de dois diferentes períodos e sua relação com a intenção de parar de utilizar. Métodos Foram avaliados alunos do 1o e do 6o ano do curso de Medicina. Regressão logística multivariada foi utilizada para avaliar a associação entre o uso de narguilé nos últimos 30 dias com os dados demográficos, psicossociais e com o nível de conhecimento sobre seus malefícios. Resultados A taxa de experimentação e do uso atual de narguilé foi elevada (59,6% e 27,7% respectivamente), sem diferença entre os grupos. O nível de conhecimento dos alunos do 6o ano acerca dos malefícios do uso de narguilé foi maior em relação aos alunos do 1o ano (p<0,0001), e não houve relação do consumo de narguilé nos últimos 30 dias com o nível de conhecimento. O tabagismo de cigarros e o uso de bebida alcoólica estavam associados ao uso de narguilé nos últimos 30 dias. Odds Ratio não ajustada de 11,3; IC95% 4,62-27,7; p<0,0001 e OR 8,74; IC95% 3,78-20,2; p<0,0001; respectivamente. Conclusões Há uma elevada experimentação, uso atual de narguilé e de cigarros entre os estudantes de Medicina, que possuem maior conhecimento sobre o malefício do uso no 6° ano do curso. Não foi observada relação entre o conhecimento sobre o malefício do uso e o consumo. O tabagismo e o uso de bebidas alcoólicas são preditores independentes de uso de narguilé.

ABSTRACT Objective This study evaluated the factors related to the use of hookah among medical students, the level of knowledge about the involved harms, and their relationship with the use and intention to stop using it. Methods Students of the 1st and 6th year of medical school were evaluated. A multivariate logistic regression model was used to evaluate the association between the outcome (use of hookah in the last 30 days) and demographic, subjective psychosocial data and level of knowledge about the harms of hookah use. Results The experimentation rate of hookah and current use was high (59.6% and 27.7%, respectively), with no difference between the 1st and 6th year groups (p=0.70). The 6th grade students were more knowledgeable about the harm of using hookah when compared to the 1st year students (p <0.0001), and there was no association between the use of hookah in the last 30 days and the knowledge about its harms. Cigarette smoking and the use of alcoholic beverages were associated with the use of hookah in the last 30 days, with unadjusted Odds Ratio (OR) of 11.3; 95% CI 4.62-27.7; p <0.0001 and OR 8.74; 95% CI 3.78-20.2; p <0.0001; respectively. Conclusion There is a high experimentation, current use of hookah and cigarettes among medical students. Sixth year students are more knowledgeable about the harms involved. There was no association between the use of hookah in the last 30 days and the knowledge about its harms. Smoking and the use of alcoholic beverages are independent predictors of use of hookah.

Fatores associados ao uso de narguilé e outros produtos do tabaco entre escolares, Brasil, 2015 / Factors associated with the use of waterpipe and other tobacco products among students, Brazil, 2015

RESUMO: Objetivo: Identificar a frequência e os fatores associados ao uso de narguilé e outros produtos do tabaco entre os escolares brasileiros. Métodos: Estudo transversal com dados da Pesquisa Nacional de Saúde do Escolar. A amostra foi composta por alunos do 9º ano do Ensino Fundamental. Foi realizada análise descritiva do uso de produtos do tabaco em 2012 e 2015. Para explorar a relação de fatores como características sociodemográficas, familiares, saúde mental e hábitos de vida com o uso de outros produtos do tabaco, foram calculados odds ratio ajustados. Resultados: O uso de outros produtos do tabaco aumentou de 4,8% (IC95% 4,6 - 5,0), em 2012, para 6,1% (IC95% 5,7 - 6,4), em 2015, com maior proporção em meninos. O narguilé foi o produto mais usado em 2015 (71,6%; IC95% 68,8 - 74,2), sendo mais frequente em meninas. Foram positivamente associados ao uso de outros produtos do tabaco: escola privada, morar com pai/mãe, trabalhar, não ter amigos, sofrer violência familiar, faltar às aulas, fazer uso de cigarros e álcool, ter experimentado drogas, já ter tido relação sexual, ter pais ou responsáveis fumantes e presenciar pessoas fumando. Os fatores de proteção foram: sexo feminino, incremento da idade, cor da pele parda ou indígena, fazer refeições com responsável, ter supervisão familiar e praticar atividade física. Conclusão: Conclui-se que o uso de outros produtos do tabaco foi elevado, com aumento nos últimos anos, destacando-se o narguilé. Torna-se importante a conscientização dos riscos e a vigilância do uso desses produtos, bem como o avanço das políticas públicas de controle do tabagismo no país.

ABSTRACT: Objective: To identify the frequency and factors associated with the use of waterpipe and other tobacco products among Brazilian students. Methods: This is a cross-sectional study based on data from the National Adolescent Student Health Survey. The sample consisted of 9th-grade students from elementary school. We conducted a descriptive analysis of the use of tobacco products in 2012 and 2015. To explore the relationship between the use of other tobacco products and factors such as sociodemographic characteristics, family, mental health, and life habits, we calculated the adjusted odds ratio. Results: The use of other tobacco products increased from 4.8% (95%CI 4.6 - 5.0) in 2012 to 6.1% (95%CI 5.7 - 6.4) in 2015, with a higher proportion among boys. Waterpipe was the most commonly used product in 2015 (71.6%; 95%CI 68.8 - 74.2), especially among girls. Factors positively associated with the use of other tobacco products were: attending private school, living with father/mother, working, not having friends, suffering domestic violence, skipping classes, consuming cigarettes and alcohol, experimenting drug, having had sex, having smoker parents or guardians, and seeing people smoking. The protective factors were: female gender, increasing age, multiracial or indigenous people, having meals with a guardian, family supervision, and practicing physical activity. Conclusion: The use of other tobacco products was high and has been increasing in recent years, particularly waterpipe. It is important to raise awareness of the risks and monitor the use of these products, as well as improve public policies of tobacco control in the country.

Factors associated with smoking contemplation and maintenance among Iranian adolescents

Background: Evidence is scarce on which factors contribute to cigarette and waterpipe contemplation and no previous study has examined the factors associated with waterpipe maintenance.

Aims: This study aimed to determine the factors associated with cigarette and waterpipe smoking contemplation and maintenance among Iranian adolescents.

Methods: Factors including depression, risky behaviour, family conflict, attitude to smoking acceptability and self-efficacy were examined using a questionnaire for 5500 adolescents at the smoking contemplation or maintenance stage.

Results: Students with depression had nearly double the chance [95% confidence interval [CI]: 1.41–2.72] of cigarette smoking contemplation. Risk takers had odds of 2.13 [95% CI: 1.51–2.94] and 1.49 [1.22–1.85] of cigarette and waterpipe [hookah] smoking contemplation, respectively. Those facing family conflict had odds of 1.87 [95% CI: 1.38–2.53] and 1.53 for cigarette and waterpipe smoking contemplation, respectively. The contemplation odds for students with more positive attitude to smoking acceptability were 2.12 [95% CI: 1.51–2.97] and 1.72 for cigarette and waterpipe smoking, respectively. Higher self-efficacy was associated with lower cigarette and waterpipe smoking contemplation. Risky behaviour was related to smoking maintenance. A more positive attitude to smoking acceptability was related to higher waterpipe maintenance [odds ratio = 1.57 95% CI: 1.03–2.40].

Conclusions: Depression, attitude to smoking acceptability and risky behaviour are factors associated with smoking contemplation and maintenance.

Effect of exclusive cigarette smoking and in combination with waterpipe smoking on lipoproteins

Objective: A significant increase in total cholesterol and LDL-C is well shown in tobacco users, as compared to non-tobacco users. The additive effects of waterpipe and cigarette smoking on LDL levels have not been studied. The study's objective was to assess the correlation between cigarette smoking and LDL levels in Lebanese cigarette smokers and to check the interaction effect of waterpipe and cigarette smoking on LDL levels

Methods: This cross-sectional study was conducted between October 2016 and February 2017 in 4 different laboratories, enrolling 308 patients [188 non-smokers, 105 cigarette smokers, 15 previous smokers]

Results: Current cigarette smoking [Beta = 25.57; p < 0.0001] was significantly associated with higher LDL levels and higher total cholesterol levels [Beta = 53.29; p < 0.0001] in exclusive cigarette smokers. Among current cigarette smokers who were current waterpipe smokers, a significant increase in LDL level was observed relative to current cigarette smokers who were not waterpipe smokers [Beta = 66.64 vs Beta = 37.37; p< 0.0001]

Conclusion: Among Lebanese current cigarette smokers, LDL levels increased relative to nonsmokers, consistent with findings in other populations. In addition, among Lebanese current cigarette smokers, current waterpipe smoking might increase adverse lipid profiles associated with adverse coronary effects more than cigarette smoking alone. The direct cause responsible for these observed variations in our study remains unidentified, with the hope that future research will reveal it
