Smoking Pattern among Adult Popultation of a Village in Raozan Upazila, Chattogram

Background: Smoking seems to be a symbol of adulthood during stress and loneliness to many people. It is well established that most adults start tobacco use in late childhood or adolescence and continue lifelong. This study aimed to determine the smoking pattern among adult populations in a selected community of Bangladesh. Materials and methods: A descriptive cross-sectional study was conducted during May 2022 among adult populations in Raozan Upazila of Chattogram. 120 adults were included in the study by convenience sampling and information were collected by face to face interview. Various statistical analysis were performed. Results: Out of 120 respondents 115(96%) were male, 20(10%) were illiterate, 50(42%) were labor and 60(50%) belonged to lower middle class. Among the total respondents, 93(77%) were married. From the study, it was observed that majority 42(30%) belonged to age between 51-60 years. Out of 120 smokers, almost 90(75%) smoked cigarettes and only 12(10%) used to chew tobacco leaves. Among the smokers, 70(58.3%) used to smoke outside the house while only 6(5%) used any hidden place to smoke. Regarding health related problems, 51(42.5%) had breathing problems and 37(30.8%) had cough. 110(91.67%) used to smoke regularly whereas 10(8.33%) used to smoke ocassionally. Conclusion: In Bangladesh, little is known by the people regarding the harmful effects of smoking and associated risk factors. Special regulations and actions should be implemented to curb current adolescent smoking patterns. IAHS Medical Journal Vol 7(1), June 2024; 40-43

Misperceptions about the effectiveness of cutting down and low-rate daily smoking for reducing the risk of tobacco-caused harm.

Reducing the amount smoked per day, or smoking at a low rate, confers limited protection from smoking harms. We aimed to quantify the prevalence of misperceptions about cutting down and low-rate smoking among Australian adults who smoke. Cross-sectional online survey in April/May 2022 (N=2,740). Participants were asked whether they agreed (misperception) or disagreed that "Reducing the number of cigarettes smoked per day is an effective way to reduce the risk of experiencing the health harms of smoking". They were also asked whether the statement "Smoking 1 cigarette per day is about 1/20th as dangerous as smoking a pack of 20 cigarettes per day" sounded about right (misperception) or if it was less dangerous (misperception) or more dangerous than that. The misperception that reducing the number of cigarettes smoked is an effective way to reduce risk was held by 72.0% of people who smoke overall, but was more common among those who smoked <5 cigarettes daily (76.3%; Adj PR=1.11 [95% CI 1.01-1.21]) or only occasionally (79.7%; Adj PR=1.14 [1.06-1.23]) compared with those who smoked 5+ cigarettes daily (66.7%). Over two-thirds (67.9%) underestimated the dangers of smoking 1 cigarette per day, and this misperception was also more common among low-rate smokers (77.6%, Adj PR=1.14 [95% CI 1.04-1.26]) compared to those who smoked 5+ cigarettes daily (63.1%). Misperceptions about the value of cutting down and low-rate smoking for reducing the risk of tobacco-caused harm are pervasive, especially among those who currently smoke at a low-rate or only occasionally. Recent epidemiological evidence confirms that the risks of harm associated with low-rate smoking and cutting down are much higher than would be expected if the relationship between consumption and harm was linear. Findings from this study indicate that misperceptions about the benefits conferred by these smoking patterns are pervasive among people who smoke, particularly among those who currently smoke at a low rate. Corrective education that explains the mechanisms for the increased risk posed by these behaviours could be delivered via package health warnings and/or public health campaigns and may provide low-rate and occasional smokers with additional reasons to quit.

Use, perceptions, and effectiveness of e-cigarettes for smoking cessation among older adults in England: a population study, 2014–2024

BackgroundThis study aimed to characterise patterns of tobacco smoking and vaping among older adults (≥ 65 years) in England, to explore harm perceptions of e-cigarettes among those who smoke, and to estimate the real-world effectiveness of e-cigarettes for helping older adults to stop smoking.MethodsData were collected as part of a representative monthly cross-sectional household survey in England between April 2014 and April 2024 (n = 197,219). We analysed differences between older (≥ 65 years) and younger/middle-aged adults (18–64 years) in (a) time trends in tobacco smoking and vaping, (b) harm perceptions of e-cigarettes vs. cigarettes (adjusting for gender, socioeconomic position, and vaping status), and (c) the real-world effectiveness of e-cigarettes for smoking cessation (adjusting for gender, socioeconomic position, characteristics of the quit attempt, and use of other evidence-based cessation aids).ResultsTobacco smoking prevalence remained relatively unchanged over time among older adults (at ~ 9%; 9.5% [8.5–10.6%] in April 2014 and 8.7% [7.7–9.8%] in April 2024) but vaping prevalence increased (from 2.1% [1.6–2.7%] to 3.7% [3.0–4.6%], respectively). These trends differed from those observed among younger/middle-aged adults, among whom there was a clear decline in smoking (from 21.8% [21.0–22.7%] to 18.2% [17.3–19.0%]) and a larger increase in vaping (from 5.6% [5.2–6.1%] to 16.2% [15.3–17.0%]). Older adults were consistently less likely than younger/middle-aged adults to use e-cigarettes to support attempts to quit smoking (26.8% [17.2–39.3%] vs. 43.7% [39.6–48.0%] in April 2024). Older smokers reported greater uncertainty about the harms of e-cigarettes compared with cigarettes (ORadj = 2.48 [2.28–2.69]). E-cigarettes appeared to be effective for helping older adults to stop smoking (ORadj = 1.50 [0.96–2.34]); whether effectiveness was lower than for younger/middle-aged adults was inconclusive.ConclusionsOver the past decade, smoking prevalence has remained stable among older adults while decreasing among the rest of the adult population in England. Older adults are more unsure about the relative harms of e-cigarettes and less likely to use them to support attempts to quit smoking, despite evidence that they are effective for smoking cessation in this population.

Evaluation of E-Cigarette Use in Opioid-Dependent Patients in Maintenance Treatment.

As tobacco smoking decreases, the use of e-cigarettes is on the rise. There is a debate whether switching from smoking to the use of e-cigarettes might represent a harm reduction strategy for those who smoke tobacco heavily, a habit often observed in individuals with opioid dependence. The present study investigated the prevalence and patterns of tobacco smoking and e-cigarette use in patients in opioid maintenance treatment (OMT) and whether e-cigarette use contributed to the cessation of smoking tobacco. In 2014 (n=84) and in 2021 (n=128), patients from two OMT clinics of a psychiatric university hospital were interviewed RESULTS: In both surveys, patients presented with a comparable average age (45.6 vs. 46.9 years of age), gender distribution (mainly male 71.4 vs. 75.8%), and length of OMT history (median: 66 vs. 55 months). The lifetime prevalence of e-cigarette use (45.2% in 2014 and 38.3% in 2021) was much higher than the current prevalence (4.9% and 7.8%, respectively). Few patients reported either a complete switch from smoking to the use of e-cigarettes (2014, n=1 vs. 2021, n=2) or the achievement of abstinence from smoking after a temporary use of e-cigarettes (2014, n=2 vs. 2021, n=1). No increase in the use of e-cigarettes was observed in these groups of patients undergoing OMT. Presumably, harm reduction strategies relating to the use of e-cigarettes in this group need to be supported by motivational interventions. Given the high morbidity and mortality due to smoking, OMT clinics should offer professional help in reducing smoking.

Blood pressure and hypertension in older adults with a history of regular cannabis use: findings from the Multi-Ethnic Study of Atherosclerosis.

Observational evidence investigating associations between cannabis use and blood pressure and hypertension is inconsistent. Cross-sectional data from 3,255 participants at Exam 6 (2016-2018) of the Multi-Ethnic Study of Atherosclerosis (MESA) were analyzed, including self-reported cannabis smoking patterns, standardized measures of systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP; BP collectively), and hypertension. ANCOVA and multivariable relative risk regression models were used to calculate adjusted means for BP and adjusted prevalence ratios (PRs) for prevalent hypertension. In fully adjusted ANCOVA models, a history of regular cannabis smoking, when compared to no history, was not significantly associated with increased SBP [mean difference: 0.1 mmHg (95% CI: -1.6-1.9)], DBP [mean difference: 0.5 mmHg (95% CI: -0.3-1.4)], PP [mean difference: -0.5 mmHg (95% CI: -1.8-0.9)], or prevalent hypertension [PR: 1.01 (95% CI: 0.93-1.10)]. Furthermore, no associations were observed for either the duration or recency (in the past month) of cannabis smoking or number of joint/pipe years. Models exploring potential interactions between a history of regular cannabis smoking and age, sex, race/ethnicity, and cigarette smoking status were not significant for either BP or hypertension. In a cohort of racially and ethnically diverse older adults with a high prevalence of hypertension, no evidence of increased risk due to regular cannabis smoking was found for either blood pressure or hypertension.

A cross-sectional study on health behavior changes during COVID-19 among adults in Malaysia.

COVID-19 has triggered significant disruptions globally, necessitating swift adaptations in individuals' health behaviors. This cross-sectional study was conducted during Phase Four of Malaysia's National Recovery Plan and examines how the pandemic has affected health behaviors among adult Malaysians. The study gathered data online using convenience sampling with 1,004 respondents aged 18 and above. The research focused on diverse health domains, including eating habits, physical activity, smoking, alcohol consumption, and sleep patterns. The Wilcoxon Signed Rank test and descriptive statistics were employed to compare health behaviors before and after COVID-19. Findings indicate noteworthy shifts in eating behaviors, with increased water and fruit consumption (p < .001). The frequency of home-cooked meals stayed relatively stable despite declining dinner preference and increasing daily snacks. Physical activity declined, marked by increased sedentary behavior and screen time (p < .001). There were differences in the patterns of smoking and alcohol consumption; some had started these behaviors during the pandemic. Notably, intentions to quit smoking among respondents were more prominent than attempts to stop drinking. Respondents' sleep patterns also changed, with more sleeping fewer than seven hours daily (p < .001). The study emphasizes the need for focused interventions to address new challenges by highlighting the impact on health behaviors. As Malaysia navigates the post-pandemic landscape, understanding and mitigating the persisting effects on health behaviors are crucial for promoting overall well-being.

Regular cannabis smoking and carotid artery calcification in the Multi-Ethnic Study of Atherosclerosis (MESA).

Studies on cannabis use and adverse cardiovascular outcomes have reported conflicting results. Research on its relationship to calcified arterial plaque remains limited. Cross-sectional data from 2152 participants at Exam 6 (2016-2018) in the Multi-Ethnic Study of Atherosclerosis (MESA) were analyzed, including self-reported cannabis smoking patterns and carotid artery calcification (CAC) as measured via computed tomography. Multivariable relative and absolute risk regression models were used to estimate adjusted prevalence ratios (PRs) and prevalence differences, respectively, for the presence of calcified plaque. Multivariable linear regression was then used to compare group differences in the extent of CAC in those with calcified plaque. A minority of participants (n = 159, 7.4%) reported a history of regular cannabis smoking. Among all participants, 36.1% (n = 777) had detectable CAC. In models adjusted for demographics, behavioral, and clinical cardiovascular disease factors, a history of regular cannabis smoking was not associated with the prevalence of CAC in either common carotid artery (PR: 1.14, 95% CI: 0.88 to 1.49). In the subset of participants with calcified plaque, and in separate fully adjusted multivariable linear regression models, a history of regular cannabis smoking was not associated with increased calcium volume (difference = 7.7%, 95% CI: -21.8 to 48.5), calcium density (difference = 0.4%, 95% CI: -6.6 to 7.9), or Agatston score (difference = 32.1%, 95% CI: -31.8 to 155.8) in either carotid artery. Models exploring potential effect modification by age, race/ethnicity, and tobacco smoking status showed no significant association, except for higher CAC prevalence in men with a history of regular cannabis smoking. In a racially and ethnically diverse cohort of older adults with a moderately high prevalence of CAC, no associations were found between a history of regular cannabis smoking, duration, or recency of cannabis smoking, and the prevalence of carotid calcified plaque. These findings were consistent across age, race/ethnicity, and cigarette smoking, except for an increased prevalence in men with a history of regular cannabis smoking. Similarly, in a subgroup with CAC, no association was found between a history of regular cannabis smoking and extent of calcification as measured by volume, density, and Agatston score.

Effect of stressors during COVID-19 lockdown on malnutrition and health-risk behaviors among Jordanian college students: A cross-sectional study.

A stressful condition such as the emergence of the coronavirus and its related lockdown measures might trigger alterations in college students' behaviors. This cross-sectional study aimed to identify the changes in college students' dietary and lifestyle behaviors during the lockdown and the effect of lockdown-related stressors on health-risk behaviors. A web-based survey was conducted among undergraduate college students in Jordan. Weight and height were reported by the students. The students' dietary and lifestyle behaviors and their changes during 1 month of the countrywide lockdown were assessed. The Perceived Stress Scale-4 was utilized to assess stress levels. Results indicated that 77.2% of the students reported weight changes. Notably, 45.9% increased their intake of unhealthy food, while and 38% opted for healthier food choices. Most students experienced alterations in physical activity (80.0%), screen time (86.2%), smoking, and sleep patterns (85.4%), with a higher tendency toward adopting health-risk behaviors. Perceptions of curfew-related stress were associated with distance learning-related stress (OR = 2.73, CI: 1.08-6.90, P = .034), and a greater change in physical activity (OR = 3.59, CI: 1.36-9.48, P = .010). Additionally, weight changes were associated with perception of other types of stressors (OR = 3.39, CI: 1.39-8.28, P = .007). Overall, there was a considerable increase in malnutrition and health-risk behaviors among students during the lockdown. Understanding students' responses to these stressful conditions and the role of stress in driving behavioral changes are crucial for developing interventions that enhance college students' adaptation to such changes and maintaining healthy dietary and lifestyle behaviors in the future.

Association Between Secondhand Smoking and Cardiovascular Health Among the U.S. Adult Population Who Participated in the 2017-2018 NHANES Survey

The purpose of this study was to expand upon previous research by investigating the relationship between exposure to secondhand smoking and cardiovascular health in the general U.S. population across various demographic variables. Methods: Using a nationally representative sample, from the 2017-2018 NHANES survey, patterns of secondhand smoking and cardiovascular health issues were examined. This relationship was examined individually and in combination with other sociodemographic characteristics such as gender, family income/poverty, race, education level, birth country, U.S. citizenship status, and language of interview using multivariate logistic regression. Results: The data included 3882 subjects including 23.6% of participants who were exposed to secondhand smoking while 76.33% had not been exposed. Individuals who reported that they were not exposed to secondhand smoke had 32.1% lower odds (95% CI: 0.56-0.82) of having cardiovascular health issues compared to individuals who reported being exposed secondhand smoke, (95% CI: 0.56-0.82). Additionally, statistically significant associations between secondhand smoking and cardiovascular health were identified when factoring in various demographic factors such as gender, ratio of family income poverty, birth country, U.S. citizenship status, education level, and cardiovascular health issues. Conclusion: These results indicate that secondhand smoking exposure should be avoided to potentially reduce the risk of cardiovascular health issues

Smoking during pregnancy in an Irish obstetric Population: Prevalence, maternal and ethnic factors

ObjectivesMaternal cigarette smoking during pregnancy is associated with adverse health outcomes for the mother and her fetus in utero. A high prevalence of smoking during pregnancy is reported within an Irish obstetric population. However, there are no recent Irish data regarding change in smoking rates over time, or factors associated with declining smoking prevalence. Therefore, the objectives of this study were: 1. To investigate smoking patterns in pregnancy among an Irish obstetric population, 2. To identify trends over time, and 3. To evaluate associated demographic factors. Study DesignThe data for this study were obtained from EuroKing, a computerised obstetric database, to which data had been entered prospectively during the 8-year period between January 2015 and December 2022 at Galway University Hospital, Ireland. A total of 22,673 deliveries were recorded during this time period. Complete information regarding the mother’s smoking history was available for 19,247 women at the time of antenatal booking, and again at delivery. Statistical analyses was performed using GraphPad Prism (version 10.1.2). Chi-square test for proportions and trend were used to assess differences between groups. ResultsRates of smoking during pregnancy declined over the duration of the study. The percentage of mothers who smoked during pregnancy declined from 8.3 % in 2015 to 6.0 % in 2022 (P = 0.007). The greatest reduction in smoking was observed among those aged 21 to 30 years, from 15.3 % in 2015 to 10.1 % in 2022 (P < 0.001). There was no significant decline in smoking within the other age groups. There was an overall reduction in the rate of smoking from the time of antenatal booking to delivery of 31.9 %. Increasing maternal age was associated with lower rates of smoking (P < 0.001). Increasing parity was associated with higher rates of smoking (P < 0.001). Smoking rates were highest in the White Irish Traveller ethnic group, at 40.3 % across the 8-year study period. Breastfeeding rates were lower in smokers versus non-smokers (P < 0.001). ConclusionThis study indicates that the rate of maternal smoking during pregnancy in Ireland is approximately 6%, which is less than previously reported. A significant proportion of women who smoked at the time of antenatal booking have ceased smoking by the time of delivery. Overall there was a decline in maternal smoking over the duration of the study. However, high rates of smoking were associated with certain sociodemographic characteristics, including younger maternal age, increasing parity and White Irish Traveller background.

Modelling the Non-linear Associations between Age and Health: Implications for Care

Abstract Background Ageing is a complex biological process that weakens the body's defences against various health problems and diseases. This decline is not uniform or linear; rather, it varies significantly among individuals. Understanding the non-linear progression of ageing is crucial for identifying critical periods where intervention might be most beneficial. This study aimed to explore nonlinearities in the association between age and health outcomes. Methods Using generalised additive models, we analysed data from the 2020 wave of the United States Health and Retirement Study. This modelling approach allows for the detailed examination of nonlinearities in health outcomes across different ages. Our sample consisted of adults aged over 50 (n = 1338; mean = 68; range = 50 – 95). We assessed seven health outcomes (heart conditions, diabetes, cholesterol, blood pressure, fatigue, back pain, and headaches) and seven protective behaviours (prostate exams, mammograms, cholesterol screenings, pap smears, flu vaccinations, dental check-ups, and smoking patterns) reflecting various aspects of health status and behaviour. Results The analysis indicated a significant and pronounced non-linear relationship between age and certain health outcomes, namely headaches, blood pressure, diabetes, and heart conditions. Additionally, ageing was non-linearly associated with specific health behaviours, including the uptake of prostate exams, mammograms, flu vaccinations, and smoking prevalence. Notably, distinct patterns emerged concerning health behaviours in relation to age-specific screening policies. Conclusion The findings of this study reveal that the probability of developing health problems or engaging in health protective behaviours do not increase/decrease linearly in direct proportion to age. Rather, the probability curve exhibits fluctuations, presenting periods of heightened odds interspersed with phases of relative stability. Such non-linearity may be partially attributed to policy decisions but could also reflect a complex interplay of factors such as weakened immune systems, access to healthcare, personal health beliefs, and the evolving perception of risk as one grows older.

Changes in Smoking Patterns in Turkey Before and After the Ban on Loose Cigarettes: An Ecological Perspective From Global Tobacco Surveillance Data.

Loose or individual cigarettes sold without packaging pose a unique challenge for tobacco control, which is the leading cause of premature and preventable mortality worldwide. This study aims to assess the changes in smoking patterns following the ban on loose cigarettes in 2008 in Turkey. Gender-stratified trend analysis of smoking patterns before and after the ban on loose cigarettes was done using the Global Tobacco Surveillance data (adults: Global Adult Tobacco Survey (GATS) 2008, 2012, and 2016; youth: Global Youth Tobacco Survey (GYTS) 2003, 2005, 2009, 2012, and 2017) from Turkey. The trends in smoking patterns were triangulated with the introduction of the loose cigarette ban and other laws in Turkey. From GATS 1 in 2008 to GATS 2 in 2012, there were initial declines in adult smoking patterns, including current smoking and daily smoking, with increased quit intentions. However, these trends were reversed by the time of the GATS 3 in 2016, when both current smoking and daily smoking measures were higher, especially among females. Monthly cigarette expenses consistently increased across all survey years. Among youths, the overall prevalence increased sharply from 6.9% in 2003 to 23% in 2005, then decreased to 8.4% in 2009, again increased to 10.4% in 2012, and finally returned to 7.7% in 2017. Triangulation of these trends against the implementation of the loose cigarette ban in 2008 produced no clear association between the ban and smoking patterns. The overall marginal decline in smoking behaviors over two decades in Turkey needs to be fast-tracked, specifically the rise of smoking among the female population, which needs to be addressed through evidence-based tobacco control interventions. The loose cigarette ban was implemented as part of a comprehensive tobacco control law, and the GATS or GYTS data is not sufficient to assess the effect of this provision. The tobacco control effort in Turkey should collect evidence for changes in smoking patterns following the implementation of tobacco interventions, which is also a mandate of the Global Tobacco Surveillance System (GTSS).

Fibrosis, biomarkers and liver biopsy in AAT deficiency and relation to liver Z protein polymer accumulation.

The course of adults with ZZ alpha-1-antitrypsin deficiency (AATD) liver disease is unpredictable. The utility of markers, including liver biopsy, is undefined. A prospective cohort, including protocol liver biopsies, was enrolled to address these questions. We enrolled 96 homozygous ZZ AATD adults prospectively at three US sites with standardized clinical evaluations, and protocol liver biopsies. Fibrosis was scored using Ishak (stages 0-6). Also, 51% of the 96 subjects had Ishak score >1 fibrosis (49% Ishak 0-1, 36% Ishak 2-3 and 15% ≥4). Elevated aspartate aminotransferase (AST) more than alanine aminotransferase (ALT), high body mass index (BMI), obesity, AST platelet ratio index and elevated serum Z alpha 1 antitrypsin (AAT) polymer levels were associated with increased fibrosis. Steatosis did not correlate to fibrosis. Increased fibrosis was associated with increased mutant Z polymer globular inclusions (p = .002) and increased diffuse cytoplasmic Z polymer on biopsy (p = .0029) in a direct relationship. Increased globule Z polymer was associated with increased serum AST (p = .007) and increased periportal inflammation on histopathology (p = .004), but there was no relationship of Z polymer hepatocellular accumulation with ALT, gamma glutamine transferase, inflammation in other parts of the lobule, necrosis or steatosis. Serum Z polymer levels were directly correlated to hepatic Z protein polymer content. Lung function, smoking and alcohol consumption patterns were not associated with fibrosis. In AATD high BMI, obesity and elevated AST are associated with increased fibrosis. Liver biopsy features are correlated to some serum tests. Serum Z AAT polymer levels could be a future biomarker to detect fibrosis early and is directly correlated to liver Z content.

Examining the onset and cessation patterns of active smoking among college students: an interpretative analysis

Smoking is a prevalent global issue, with a significant risk factor for various non-communicable diseases necessitating prolonged, costly, and potentially devastating medical treatments. In addition, infectious diseases such as tuberculosis, COVID-19, and pneumonia in toddlers are often associated with active and passive smoking habits. The correlation is evident across diverse demographics, encompassing individuals of varying ages, professions, and genders. Therefore, this research aimed to explore and describe behavior of active smokers among campus members at various universities, focusing on the initiation, cessation, and influencing factors associated with smoking.A qualitative research design was used with a hermeneutic phenomenological approach, where information was provided by five active smoker informants.These individuals started smoking as teenagers, and the fluctuating patterns were influenced by health concerns or a perceived lack of significance attributed to smoking. However, the periods of abstinence were only temporary due to the pervasive influence of social and environmental factors. The initiation of smoking commonly started from the influence of close acquaintances, such as family members. Meanwhile, the process of quitting encountered numerous obstacles, primarily from potent social factors outweighing personal intentions.The implementation of smoking cessation strategies posed challenges due to the profound impacts of addiction, requiring unwavering determination, comprehensive plans, and diligent efforts.

Association of Smoking Patterns with Vision-Related Disability According to Glaucoma Subtypes

ABSTRACT Objective The relationship between smoking and onset of glaucoma has been inconsistent. However, there is a gap in understanding whether tobacco smoking is linked to a worse visual impairment in different glaucoma subtypes. The objective of this study was to examine the association between smoking behavior and vision-related disability in people who have different glaucoma subtypes. Methods A total of 283 people with primary open-angle glaucoma (POAG), primary angle closure glaucoma (PACG), normal tension glaucoma (NTG), and pseudo-exfoliative (PEX) were included in this cross-sectional study. The recruitment of study participants was organized in one of two tertiary centers for eye diseases in Belgrade, Serbia, during their regular eye checks. Information about the duration and quantity of smoking was self-reported. Vision-related impairment was quantified using a validated Glaucoma Quality of Life-15 (GQL-15) questionnaire. Results A series of multiple linear regression models adjusted for age, gender, severity of glaucoma, lifestyle, and mobility, intraocular pressure level, visual parameters, previous and current therapy, and chronic illnesses suggested that a higher quantity of cigarettes smoked per day was associated with poorer vision-related quality of life only among people with NTG subtypes. This association was absent when smoking duration was tested in the adjusted linear regression model. Conclusion A higher number of cigarettes smoked daily was associated with poorer vision-related impairment among people who have NTG, but not other glaucoma subtypes. It is recommended that ophthalmologists and other health-care professionals work to improve their patients’ understanding of harmful effects of tobacco smoke and quit smoking.

Smoking, all-cause, and cause-specific mortality in individuals with diabetes in Mexico: an analysis of the Mexico city prospective study

ObjectiveEvidence from low- and middle-income countries regarding the effect of smoking in people with diabetes is lacking. Here, we report the association of smoking with mortality in a large cohort of Mexican adults with diabetes.MethodsParticipants with diabetes mellitus (self-reported diagnosis, use of antidiabetic medications or HbA1c ≥ 6.5%) aged 35–74 years when recruited into the Mexico City Prospective Study were included. Cox regression confounder-adjusted mortality rate ratios (RRs) associated with baseline smoking status were estimated.ResultsAmong 15,975 women and 8225 men aged 35–74 years with diabetes but no other comorbidities at recruitment, 2498 (16%) women and 2875 (35%) men reported former smoking and 2753 (17%) women, and 3796 (46%) men reported current smoking. During a median of 17 years of follow-up there were 5087 deaths at ages 35–74 years. Compared with never smoking, all-cause mortality RR was 1.08 (95%CI 1.01–1.17) for former smoking, 1.11 (95%CI 1.03–1.20) for current smoking, 1.09 (95%CI 0.99–1.20) for non-daily smoking, 1.06 (95%CI 0.96–1.16) for smoking < 10 cigarettes/day (median during follow-up 4 cigarettes/day), and 1.28 (95% CI 1.14–1.43) for smoking ≥ 10 cigarettes/day (median during follow-up 15 cigarettes/day). Mortality risk among daily smokers was greatest for COPD, lung cancer, cardiovascular diseases, and acute diabetic complications.ConclusionIn this cohort of Mexican adults with diabetes, low-intensity daily smoking was associated with increased mortality, despite observing smoking patterns which are different from other populations, and over 5% of total deaths were associated with smoking.

54353 A Meta-Analysis Study on Smoking and Male Pattern Hair Loss

54353 A Meta-Analysis Study on Smoking and Male Pattern Hair Loss

2024 Guidelines of the Taiwan Society of Cardiology on the Primary Prevention of Atherosclerotic Cardiovascular Disease --- Part I.

Atherosclerotic cardiovascular disease (ASCVD) is one of the leading causes of death worldwide and in Taiwan. It is highly prevalent and has a tremendous impact on global health. Therefore, the Taiwan Society of Cardiology developed these best-evidence preventive guidelines for decision-making in clinical practice involving aspects of primordial prevention including national policies, promotion of health education, primary prevention of clinical risk factors, and management and control of clinical risk factors. These guidelines cover the full spectrum of ASCVD, including chronic coronary syndrome, acute coronary syndrome, cerebrovascular disease, peripheral artery disease, and aortic aneurysm. In order to enhance medical education and health promotion not only for physicians but also for the general public, we propose a slogan (2H2L) for the primary prevention of ASCVD on the basis of the essential role of healthy dietary pattern and lifestyles: "Healthy Diet and Healthy Lifestyles to Help Your Life and Save Your Lives". We also propose an acronym of the modifiable risk factors/enhancers and relevant strategies to facilitate memory: " ABC2D2EFG-I'M2 ACE": Adiposity, Blood pressure, Cholesterol and Cigarette smoking, Diabetes mellitus and Dietary pattern, Exercise, Frailty, Gout/hyperuricemia, Inflammation/infection, Metabolic syndrome and Metabolic dysfunction-associated fatty liver disease, Atmosphere (environment), Chronic kidney disease, and Easy life (sleep well and no stress). Some imaging studies can be risk enhancers. Some risk factors/clinical conditions are deemed to be preventable, and healthy dietary pattern, physical activity, and body weight control remain the cornerstone of the preventive strategy.

Social, Behavioral, and Clinical Risk Factors Are Associated with Clonal Hematopoiesis.

Risk factors including smoking, alcohol intake, physical activity (PA), and sleep patterns have been associated with cancer risk. Clonal hematopoiesis (CH), including mosaic chromosomal alterations and clonal hematopoiesis of indeterminate potential, is linked to increased hematopoietic cancer risk and could be used as common preclinical intermediates for the better understanding of associations of risk factors with rare hematologic malignancies. We analyzed cross-sectional data from 478,513 UK Biobank participants without hematologic malignancies using multivariable-adjusted analyses to assess the associations between lifestyle factors and CH types. Smoking was reinforced as a potent modifiable risk factor for multiple CH types, with dose-dependent relationships persisting after cessation. Males in socially deprived areas of England had a lower risk of mosaic loss of chromosome Y (mLOY), females with moderate/high alcohol consumption (2-3 drinks/day) had increased mosaic loss of the X chromosome risk [OR = 1.17; 95% confidence interval (CI), 1.09-1.25; P = 8.31 × 10-6] compared with light drinkers, active males (moderate-high PA) had elevated risks of mLOY (PA category 3: OR = 1.06; 95% CI, 1.03-1.08; P = 7.57 × 10-6), and men with high body mass index (≥40) had reduced risk of mLOY (OR = 0.57; 95% CI, 0.51-0.65; P = 3.30 × 10-20). Sensitivity analyses with body mass index adjustment attenuated the effect in the mLOY-PA associations (IPAQ2: OR = 1.03; 95% CI, 1.00-1.06; P = 2.13 × 10-2 and IPAQ3: OR = 1.03; 95% CI, 1.01-1.06; P = 7.77 × 10-3). Our study reveals associations between social deprivation, smoking, and alcohol consumption and CH risk, suggesting that these exposures could contribute to common types of CH and potentially rare hematologic cancers. This study underscores the impact of lifestyle factors on CH frequency, emphasizing social, behavioral, and clinical influences and the importance of sociobehavioral contexts when investigating CH risk factors.

A multicomponent smoking cessation program for adults with Type 2 Diabetes Mellitus (DiMe-SALUD2 project): A study protocol of a randomized controlled trial

BackgroundTobacco use represents a significant public health burden, being especially harmful for smokers with Type 2 Diabetes Mellitus (T2DM). Effective smoking cessation interventions are required for this vulnerable population. The goal is to describe a study protocol of a randomized controlled trial (RCT) aimed at analyzing the effectiveness and efficiency of a multicomponent smoking cessation intervention for T2DM smokers, including a training protocol on healthy lifestyle habits and self-management of T2DM (DiMe-SALUD2 project). MethodsThis RCT will assign participants to: (1) Control Group (n = 30), including a brief psychoeducation advice about smoking cessation; (2) Cognitive-behavioral treatment (CBT) for smoking cessation (n = 30), based on a multicomponent program implemented in group-based sessions over an eight-week period; and (3) CBT plus DiMeSALUD2 protocol (n = 30), which will develop an additional psychoeducational protocol specifically designed to improve healthy lifestyle habits. Participants will be assessed at baseline, post-treatment and several follow-ups (1-, 6- and 12-months). Primary outcomes will include smoking abstinence (24-h point prevalence abstinence at post-treatment and 7-day point prevalence at follow-ups) and smoking continuous abstinence. Secondary outcomes will include treatment retention, changes in smoking patterns and nicotine dependence, as well as the impact on T2DM clinical variables, mental health, and quality of life. DiscussionThe DiMeSALUD2 program could assist T2DM smokers in quitting tobacco use and improving their overall quality of life. This project will help incorporating improvements in routine clinical practice with T2DM patients, offering a smoking cessation program adapted to their specific needs.
