Tobacco use among the elderly: a systematic review and meta-analysis

Substance Use and Psychological Distress in Mexican Adults during COVID-19 Pandemic: A Cross-Sectional Study

OBJECTIVES

This observational cross-sectional study examined changes in substance use during the coronavirus disease 2019 (COVID-19) pandemic in the Mexican population and evaluated whether depression or anxiety was associated with these new consumption patterns.

METHODS

An online survey was distributed to the general population. Participants were questioned about their demographics, situation during the COVID-19 pandemic, and substance consumption patterns. The Patient Health Questionnaire-9 for depression and the Coronavirus Anxiety Scale were used.

RESULTS

A total of 866 individuals completed the survey. The mean scores for the Patient Health Questionnaire-9 and Coronavirus Anxiety Scale were 8.89 ± 6.20 and 3.48 ± 3.22, respectively. The preferred substances were alcohol (19%), tobacco (16.5%), and marijuana (5.6%). Consumption of alcohol (p = 0.042) significantly increased during the pandemic and it was higher in women than in men (p = 0.040).

CONCLUSIONS

Substance use patterns were affected by the pandemic, with an increase in the number of users and consumption rate, as well as the reported psychiatric symptoms.

Does the association between smoking and mortality differ due to frailty status? A secondary analysis from the Mexican Health and Aging Study

BACKGROUND

despite the well-known adverse health effects of smoking, evidence of these effects on frail individuals is still scarce.

AIMS

to assess whether frailty influences the association between smoking and mortality.

METHODS

individuals ≥50 years from the Mexican Health and Aging Study were analysed. Mortality rates from a 17-year follow-up were compared between smoking status groups (never, previous and current) and other smoking behaviour-related characteristics (pack-years, age commenced and cessation). Baseline variables were included to adjust the Cox regression models. First, models were adjusted for the whole sample, including an interaction term between the frailty index (FI) and smoking variables. A second set of models were stratified by FI levels: 0.00-0.10, 0.11-0.20, 0.21-0.30 and ≥ 0.31.

RESULTS

from a total 14,025 individuals, mean age was 62.4 (95% confidence interval [95% CI]: 62.1-62.8) and 53.9% were women (95% CI: 52.4-55.6). Main results from the survival analyses showed that when including FI interaction term with smoking status, comparing current to never smoking, the hazard ratio (HR) was 2.03 (95% CI: 1.07-3.85, P = 0.029), and comparing current to previous smoking, the HR was 2.13 (95% CI: 1.06-4.26, P = 0.032). Models stratified by FI levels showed a significant HR only for the two highest level groups. Similar results were found for the smoking behaviour-related characteristics.

DISCUSSION

our results suggest that frailty could modify smoking mortality risk. Other smoking characteristics were impacted by frailty, in particular, cessation. It was noteworthy that having ≥10 years of tobacco cessation was beneficial for frail individuals.

CONCLUSIONS

smoking has a higher toll on frail individuals, but ceasing is still beneficial for this group.

Late-life drinking and smoking in primary care users in Brazil

To estimate the prevalence of at-risk drinking and smoking and associated factors among older adults in primary care in Brazil. A cross-sectional study carried out in seven primary care units with 503 older adults (60+), in a city in the state of Sao Paulo, Brazil. At-risk drinking was defined by AUDIT-C and by consumption of units per week. Poisson regression was used to assess the association between the sociodemographic and health characteristics and smoking and at-risk drinking. The median age of the 503 participants was 69.6 (SD ± 6.7; range:60-93). One third of participants (33.6%) were current drinkers, 16% were at-risk drinkers (AUDIT-C), 4% at-risk drinkers (units per week), and 13% of the sample were regular smokers. The prevalence of at-risk drinking (AUDIT-C) was higher for males (RP: 4.89; 95% CI: 2.52-9.49) and for those with higher levels of education (RP: 1,861.85 95% CI: 1.08-3.14), and lower for those over the age of 70 (RP: 0.50; 95% CI: 0.30-0.84). The prevalence of smoking was higher for those with depressive symptoms (RP: 1.95; 95% CI: 1.03-3.66), and lower for those over age 70 (RP: 0.52; 95% CI: 0.29-0.94). The results point to a set of factors associated with at-risk drinking (being male, younger and having a higher education), and with smoking (being younger and having depressive symptoms). Our findings could help health professionals to identify at-risk drinkers and smokers, as well as support strategies for future interventions by the identification of the groups most vulnerable to these behaviors.

Smoking and loneliness in older adults: a population-based study in Campinas, São Paulo State, Brazil

This study aims to analyze the relationship between social isolation and loneliness with smoking in older adults. This is a cross-sectional, population-based study performed with 986 individuals aged 60 years or older. Data were collected from the Health Survey of the Municipality of Campinas (ISACamp 2014/2015), state of São Paulo, Brazil. We estimated the prevalence of smoking and smoking cessation according to independent variables and tested the associations using the chi-square test, considering a 5% significance level. Adjusted prevalence ratios were calculated using simple and multiple Poisson regression. Smoking and smoking cessation were not associated with most variables that indicate objective social isolation. “Often or always” loneliness was related to a higher prevalence of smoking (PR = 2.25; 95%CI: 1.38-3.66) whereas loneliness accompanied of self-reported emotional problems or common mental disorders was strongly associated with smoking and with lower smoking cessation (PR = 6.24; 95%CI: 1.37-28.47 and PR = 0.46; 95%CI: 0.28-0.77, respectively). These findings indicate that loneliness is a psychosocial aspect related to tobacco use which hinders smoking cessation in older adults, emphasizing the importance of emotional problems in this association.

Association of smoking status and health-related quality of life: difference among young, middle-aged, and older adults in Shandong, China

PURPOSE

Few studies explored the relationship between smoking status and health-related quality of life (HRQOL) among adults in China. This study aims to explore the relationship between smoking status and HRQOL among adults (18 +) and examine whether there is a difference in this relationship among young, middle-aged, and older adults in China.

METHODS

A total of 23,021 respondents were included in this study. The HRQOL is measured by EQ-5D-3L. The smoking status is divided into never smokers, current smokers, and former smokers. Tobit regression and Logistic regression are employed to explore the association between smoking status and HRQOL. The interaction term is included to explore the difference among young, middle-aged, and older adults.

RESULTS

This study finds smoking status is significantly associated with HRQOL. An interaction analysis shows that the association between smoking status and HRQOL is significantly different among young, middle-aged, and older adults (P < 0.05). The smoking status is only significantly associated with HRQOL in middle-aged and older adults, but not for young adults. Compared with never smokers, former smokers report significantly lower EQ-5D-3L utility value in middle-aged adults (coefficient =  - 0.089; 95%CI - 0.128 to - 0.050), current smokers report significantly higher EQ-5D-3L utility value in older adults (coefficient = 0.041; 95%CI 0.005 to 0.076).

CONCLUSIONS

This study demonstrates a significant association between smoking status and HRQOL among adults in China, and there is a difference in this relationship among young, middle-aged, and older adults. The government should take efforts to formulate a variety of measures to control tobacco use among adults.

Prevalence and Predictors of Current and Former Tobacco Use among Older Adults in Indonesia

Purpose:

The study aims to describe sociodemographic and health variable indices related to current and former tobacco use among older adults who participated in the Indonesia Family Life Survey (IFLS-5) in 2014-15.

Materials and Methods:

A national population-based cross-sectional study was conducted with a probability sample of 8,001 aged 50 years or older Indonesians.

Results:

The overall prevalence of current tobacco use was 33.3% (62.2% in men and 6.5% in women) and former tobacco use was 9.8% (17.4% among men and 2.8% in women), of which 64.4% quit tobacco use when 50 years and older. In multinomial regression analysis, sociodemographic factors (being male, lower education, lower economic status, living in Java and rural residence) and health variables (cancer or malignant tumour, depression symptoms, functional disability and inadequate fruit and vegetable consumption) were associated with current tobacco use. In addition, being overweight or obese, having had a stroke, and other lung conditions were inversely associated with current tobacco use. Further, in adjusted analysis, sociodemographic factors (being 70 years and older, being male, living in Sumatra) and having chronic conditions (dyslipidemia, heart problems, asthma, stomach or digestive diseases and functional disability) were associated with former tobacco use.

Conclusions:

A high rate of current tobacco use and low rate of former tobacco use was found, particularly among men. The identified risk factors may help to better target this vulnerable population with tobacco cessation programmes.

Morbidity patterns and healthcare utilisation among older people in Malaysia: 1996-2015

OBJECTIVE

This article examines the trends in morbidities and healthcare utilisation in Malaysian older people aged 60 years and above.

STUDY DESIGN

This is a repeated cross-sectional study.

METHODS

Data from three nation-wide community-based surveys, which were conducted in 1996, 2006, and 2015 were analysed. Multivariate analysis was performed for 2015 data to identify factors associated with healthcare utilisation.

RESULTS

Analysis noted increasing trends in the prevalence of diabetes, hypertension, hypercholesterolaemia and obesity from 1996 to 2015. Decreasing trends were noted in the prevalence of current smokers and drinkers over this 20-year period, whereas health service utilisation increased with age in all surveys. In 2015, both inpatient and outpatient care are significantly associated with increasing age and diabetes.

CONCLUSIONS

Increasing trends of health problems and healthcare utilisation were observed among older people in Malaysia. Policymakers should plan for appropriate resources to meet the challenges of an ageing population in Malaysia.

Tobacco use and its impact on pulmonary health among elderly population in rural area of Muzaffarnagar - A cross-sectional study

BACKGROUND

The tobacco use is significant in Indian rural population. Among them, elderly people in rural area are at special risk due to ageing and other factors. The impact of tobacco use on elderly health, therefore, needs to be studied in depth in rural context.

OBJECTIVE

To study the patterns of tobacco use and its consequent impact on pulmonary health of the elderly.

DESIGN AND METHODOLOGY

A community-based cross-sectional study was done (April 1st to September 30th, 2014) in the field practice area (village Bilaspur) of Rural Health Training Centre (RHTC) of Muzaffarnagar Medical College, Muzaffarnagar. A simple random sampling was used and elderly of 60 years and above were interviewed by semi-structured interview schedule. The data were analyzed by software Epi-info. version 7.1.3.3.

RESULTS AND CONCLUSION

The prevalence of tobacco usage among elderly was 56.7%, in which smoking was the dominant one (37%) and majority being in the form of Bidi (56.7%). Tobacco usage was significantly associated not only with age, sex, and caste (p<0.05 each), but occupational and socio-economic status (p<0.01 each) also; however, literacy was the most significant factor (p<0.0001) among all. The tobacco usage in smoking form was highly significantly associated with the presence of chronic obstructive pulmonary disease (p<0.0001), elucidating a significant impact on their pulmonary health. The rural elderly people need health education regarding curtailing the use of tobacco for their better health from health clinics.

Prevalence and predictors of tobacco use in the elderly

OBJECTIVE

Smoking is a well-established public health issue, which has not been examined previously among the elderly in Singapore. This paper describes and identifies the current prevalence and predictors of tobacco use among the older resident population.

METHODS

Data were derived from the Well-being of the Singapore Elderly study, a cross-sectional epidemiological study of the elderly in Singapore. Sociodemographic data from 2565 Singapore residents aged 60 years and above were collected through face-to-face interviews. Multinomial logistic regression analyses identified predictors of tobacco use.

RESULTS

A total of 236 respondents were current tobacco users (9.5%). The majority of older tobacco users were men (88.1%). Significant predictors of tobacco use were gender, marital status, and education level. Younger age (60-74 years old) was associated with more tobacco use, and the completion of tertiary education with lower rates of use.

CONCLUSIONS

Smoking prevalence among the elderly was lower than that of the Singapore general adult population (16%). However, the rate is still high and is of concern given the likelihood of a higher rate of physical disorders, which could be worsened with tobacco use. The identification of those at risk enables them to be targeted for smoking cessation programs and other interventions. Copyright © 2015 John Wiley & Sons, Ltd.

Quantification of the smoking-associated cancer risk with rate advancement periods: meta-analysis of individual participant data from cohorts of the CHANCES consortium

BACKGROUND

Smoking is the most important individual risk factor for many cancer sites but its association with breast and prostate cancer is not entirely clear. Rate advancement periods (RAPs) may enhance communication of smoking related risk to the general population. Thus, we estimated RAPs for the association of smoking exposure (smoking status, time since smoking cessation, smoking intensity, and duration) with total and site-specific (lung, breast, colorectal, prostate, gastric, head and neck, and pancreatic) cancer incidence and mortality.

METHODS

This is a meta-analysis of 19 population-based prospective cohort studies with individual participant data for 897,021 European and American adults. For each cohort we calculated hazard ratios (HRs) for the association of smoking exposure with cancer outcomes using Cox regression adjusted for a common set of the most important potential confounding variables. RAPs (in years) were calculated as the ratio of the logarithms of the HRs for a given smoking exposure variable and age. Meta-analyses were employed to summarize cohort-specific HRs and RAPs.

RESULTS

Overall, 140,205 subjects had a first incident cancer, and 53,164 died from cancer, during an average follow-up of 12 years. Current smoking advanced the overall risk of developing and dying from cancer by eight and ten years, respectively, compared with never smokers. The greatest advancements in cancer risk and mortality were seen for lung cancer and the least for breast cancer. Smoking cessation was statistically significantly associated with delays in the risk of cancer development and mortality compared with continued smoking.

CONCLUSIONS

This investigation shows that smoking, even among older adults, considerably advances, and cessation delays, the risk of developing and dying from cancer. These findings may be helpful in more effectively communicating the harmful effects of smoking and the beneficial effect of smoking cessation.

Prevalence of smoking and its associated factors with smoking among elderly smokers in Malaysia: findings from a nationwide population-based study

BACKGROUND

The determination of smoking prevalence and its associated factors among the elderly could provide evidence-based findings to guide the planning and implementation of policy in order to will help in reducing the morbidity and mortality of smoking-related diseases, thus increase their quality of life. This paper describes the rate of smoking and identifies the factor(s) associated with smoking among the elderly in Malaysia.

METHODS

A representative sample of 2674 respondents was obtained via a two-stage sampling method in proportion to population size. Face-to-face interviews were conducted using a set of standardized validated questionnaire. Data was weighted by taking into consideration the complex sampling design and non-response rate prior to data analysis. Univariable and multivariable logistic regression were used to determine the factor/s associated with smoking.

RESULTS

The prevalence of non-smokers, ex-smokers and current smokers among Malaysians aged 60 years and above were 36.3 % (95 % CI = 32.7-39.8), 24.4 % (95 % CI = 21.2-27.5) and 11.9 % (95 % CI = 9.5-14.3), respectively. Current smokers were significantly more prevalent in men (28.1 %) than in women (2.9 %), but the prevalence declined with advancing age, higher educational attainment, and among respondents with known diabetes, hypertension and hypercholesterolemia. Multivariable analysis revealed that males (aOR, 18.6, 95 % CI 10.9-31.9) and other Bumiputras (aOR 2.58, 95 % CI 1.29-5.15) were more likely to smoke. in addition, elderly with lower educational attainment (aOR, 1.70, 95 % CI 1.24-7.41) and those without/unknown hypertension also reported higher likelihood to be current smokers (aOR 1.98, 95 % CI 1.35-2.83). However, there were no significant associations between respondents with no/unknown diabetes or hypercholesterolemia with smoking.

CONCLUSIONS

In short, smoking is common among elderly men in Malaysia. Therefore, intervention programs should integrate the present findings to reduce the smoking rate and increase the smoking cessation rate among the elderly in Malaysia and subsequently to reduce the burden of smoking-related disease.

Spirometric obstruction and tobacco exposure among male Turkish nursing home residents

Spirometric obstruction is a prevalent problem in older adults and related to life-style risk factors. Symptoms related to chronic-obstructive-pulmonary-disease (COPD) are also prevalent symptoms with diverse etiologies - not limited to pulmonary obstruction. Older adults may have unrecognized airway obstruction due to functional limitations or symptoms mis-attributed to age/other co-morbidities. Therefore, spirometric obstruction may clinically be over/under diagnosed. Over last few decades, the burden of smoking-related diseases has increased in older adults. Additional evidence regarding older adults is required. We aimed to study frequency of spirometric obstruction, its over/under diagnosis and tobacco exposure in a group of male nursing-home residents. For spirometric obstruction diagnosis, two different thresholds [(fixed value: 0.70) versus (age-corrected value: 0.65 in residents >65 years of age)] were compared for better clinical practice. One hundred and three residents with 71.4 ± 6.3 years-of-age included. Spirometric obstruction prevalences were 39.8 and 29.1% with fixed and age-corrected FEV1/FVC thresholds, respectively. Age-corrected FEV1/FVC threshold underdiagnosed COPD in 1.9% while fixed threshold overdiagnosed spirometric obstruction in 8.7%. Active smokers were 64.1%, ex-smokers 23.3% and non-smokers 12.6%. Our study suggests high prevalences of spirometric obstruction and smoking in male nursing-home residents in Turkey. We suggest the use of age-corrected FEV1/FVC threshold practicing better than the use of fixed FEV1/FVC threshold in this patient group.

Real-world comparative study of behavioral group therapy program vs education program implemented for smoking cessation in community-dwelling elderly smokers

BACKGROUND

Tobacco smoking is known to be an important contributor to a wide variety of chronic diseases, especially in older adults. Information on health policy and practice, as well as evaluation of smoking cessation programs targeting older people, is almost nonexistent.

PURPOSE

To compare the real-world implementation of behavioral group therapy in relation to education alone for elderly smokers.

MATERIALS AND METHODS

Elderly smokers ready to quit smoking were identified from a cohort who completed a questionnaire at a smoking exhibition. They were allocated into two groups, behavioral therapy (3 days 9 hours) and education (2 hours), depending on their preferences. Demographic data, the Fagerstrom test for nicotine dependence (FTND) score, and exhaled carbon monoxide level were recorded at baseline. Smoking status of all subjects was followed at months 3, 6, and 12. Statistical differences in continuous abstinence rate (CAR) between the two groups were analyzed using chi-square tests.

RESULTS

Two hundred and twenty-four out of 372 smoking exhibition attendants met the enrollment criteria; 120 and 104 elected to be in behavioral group therapy and education-alone therapy, respectively. Demographic characteristics and smoking history were similar between both groups, including age, age of onset of smoking, years of smoking, smoking pack-years, education level, and nicotine dependence as measured by the FTND scale. The CAR of the behavioral therapy group at the end of the study (month 12) was significantly higher than the education group (40.1% vs 33.3%, P=0.034). Similar results were also found throughout all follow-up visits at month 3 (57.3% vs 27.0%, P<0.001) and month 6 (51.7% vs 25%, P<0.001).

CONCLUSION

Behavioral group therapy targeting elderly smokers could achieve higher short-and long-term CARs than education alone in real-world practice.

Changes in and patterns of smoking exposure in an elderly urban population in Beijing: 2001-2010

OBJECTIVE

The study aims to explore the patterns and changes of active and passive smoking in the elderly population.

METHODS

Two cross-sectional surveys with representative samples of urban populations, aged between 60 and 95 years old, were conducted in 2001 and 2010 in Beijing. A current smoker was defined as a person who smoked a tobacco product at the time of the survey, and a passive smoker was defined as a person who had been exposed to smoke exhaled by a smoker for more than 15 minutes per day more than once per week.

RESULTS

A total of 2,277 participants in 2001 and 2,102 participants in 2010 completed the survey. The current smoking prevalence changed slightly in males (24.7 vs. 21.2%, P = 0.081), while the prevalence in females decreased significantly from 8.8% (95% CI: 7.3-10.3%) in 2001 to 4.1% (95% CI: 3.0-5.2%) in 2010 (P<0.001). The prevalence of passive smoking was 30.5% (95% CI: 28.6-32.4%) in 2001 and 30.0% (95% CI: 28.1-32.0%) in 2010. The main source of secondhand smoke switched from a spouse in 2001 to offspring in 2010. This trend was observed in both sexes. Passive smoking in males from a smoking spouse decreased from 5.7% to 2.4% (P<0.001), while that from smoking offspring increased from 7.3 to 14.5% (P<0.001). Passive smoking in females from a spouse decreased from 30.6 to 17.6%, while that from offspring increased from 5.3 to 15.4% (P<0.001).

CONCLUSION

Offspring became the main source of secondhand smoke for the elderly. Our findings demonstrated the importance of implementing smoking prevention programs, to educate older adults who live with a smoking spouse and/or offspring.

Trends in tobacco consumption in three different birth cohorts of elderly of São Paulo, Brazil

BACKGROUND

The effects of birth cohorts reflect the historical differences in physical and social environments. The objectives of the present study were to describe the tobacco consumption and to evaluate the behavioral trends with respect to smoking in three different birth cohorts of a population-based sample of elderly individuals.

METHODS

A series of three cross-sectional studies conducted with elderly individuals of 60-64 years of age interviewed in 2000 (birth cohort 1936-1940; n=427), 2006 (birth cohort 1942-1946; n=298) and 2011 (birth cohort 1947-1951; n=355) in a population-based sample from the city of São Paulo, Brazil. The interviewees were participating in a prospective cohort study entitled Health, Well-Being and Aging (Saúde, Bem-Estar e Envelhecimento [SABE]). Data on tobacco consumption were self-reported and interviewees were then classified as never smokers, former smokers or current smokers. Linear model for categorical data was used to test differences on tobacco consumption between three birth elderly cohorts.

FINDINGS

Men were more likely than women to be smokers. Being evangelical and having more schooling constituted protective factors against smoking. Regarding trends, the tobacco consumption of the men did not change in any of the three cohorts studied (p=0.7454), whereas there was an increase in the number of women smokers, principally former smokers, over the periods evaluated (p=0.0189).

CONCLUSIONS

These results suggest that the anti-smoking policies implemented in Brazil were effective in women of this age group; however, different prevention strategies are required to target elderly men.

Nationwide Smoking Cessation Treatment Support Program--Turkey project

BACKGROUND

In 2011, Turkish Ministry of Health (MoH) initiated a nation-wide "Smoking Cessation Treatment Support Program" (SCTSP), to provide smoking cessation drugs free of charge.

METHODS

SCTSP was conducted in all 81 cities of Turkey, at 228 smoking cessation clinics, and by over 400 physicians. In total, 164,733 participants took advantage of the program between January and November 2011. Varenicline (Champix(®), Pfizer) and Bupropion (Zyban(®), GlaxoSmithKline) were used in the program at a ratio of 0.7 and 0.3 respectively. Post-program data were obtained by phone interviews from randomly selected participants, who had completed a 1-year follow-up after enrollment in the program.

FINDINGS

Quit rates were 29.6% for those given Varenicline and 25.1% for those given Bupropion. The quit rates for participants with hypertension (35.0%), diabetes mellitus (36.9%), coronary artery disease (32.1%) and cerebrovascular events (34.0%) were higher than those without. Increased age, female gender, longer duration of cessation drug use, low Fagerstrom score, the presence of hypertension, the absence of chronic obstructive pulmonary disease, and the absence of cancer were found to be associated with higher success rates.

INTERPRETATION

SCTSP is the first successful report of a nation-wide community-based smoking cessation intervention. The real-life quit rates obtained herein are comparable to those of clinical evidence to date. The centralization of smoking cessation clinics, standardization of treatment guidelines, application of a specific drug assignment algorithm, and provision of primary care support and follow-ups by trained physicians, appeared to be key elements for success.

Fatores sociodemográficos e econômicos associados ao tabagismo na população idosa

Objetivos Identificar a condição tabágica dos idosos e verificar os fatores sociodemográficos e econômicos associados ao hábito de fumar nessa população. Métodos Trata-se de um estudo quantitativo, transversal, observacional e analítico, com 980 idosos da zona urbana do município de Uberaba-MG. Utilizaram-se os instrumentos Miniexame do Estado Mental (MEEM) e Questionário Brasileiro de Avaliação Funcional e Multidimensional (BOMFAQ). Os idosos foram classificados como tabagistas, ex-tabagistas e não tabagistas de acordo com as Diretrizes para Cessação do Tabagismo. As análises procederam por meio do software SPSS-17. A condição tabágica dos idosos foi descrita por meio de frequências simples e absolutas. Aplicou-se o teste Cramer’s V (p ≤ 0,05) na análise bivariada e em seguida a Regressão Logística Multinomial Múltipla (p ≤ 0,05) ajustados para sexo e faixa etária de acordo com a classificação tabágica. Resultados Encontraram-se 122 (12,4%) idosos tabagistas, 320 (32,7%) ex-tabagistas e 538 (54,9%) não tabagistas. Os idosos tabagistas apresentaram-se com 3,57, 2,36 e 1,82 mais riscos de chances de ser do sexo masculino (p < 0,001), estar na faixa etária de 60 a 69 anos (p = 0,004) e não ter companheiro(a) (p = 0,008), respectivamente. Para os idosos ex-tabagistas, também foi encontrada maior chance de risco (5,34) para o sexo masculino (p < 0,001). Conclusão Os resultados evidenciam que o sexo, a faixa etária e a situação conjugal são fatores associados ao tabagismo na população idosa.

Implications of tobacco smoking on the oral health of older adults

Cigarette smoking is the foremost health risk issue affecting individuals of all age groups globally. It specifically influences the geriatric population as a result of chronic exposure to toxins. Its role in various systemic and oral diseases including cancer, premalignant lesions, periodontitis, tooth loss, dental caries and implant failures is well established. Smoking causes immuno-inflammatory imbalances resulting in increased oxidative stress in the body. The latter hastens the immunosenescence and inflammaging process, which increases the susceptibility to infections. Thus, implementation of smoking cessation programs among older adults is imperative to prevent the development and progression of oral and systemic diseases. The present review focuses on smoking-associated oral health problems in older adults, and the steps required for cessation of the habit.

Patterns of smoking prevalence among the elderly in Europe

Scant information is available on determinants of smoking prevalence in the vulnerable population of the elderly, particularly in Europe. Therefore, we analyzed smoking patterns among older adults (≥65 years old), using data from a representative survey based on 3,071 elderly, conducted in 17 European countries in 2010, within the Pricing Policies And Control of Tobacco in Europe (PPACTE) project. Overall smoking prevalence in 17 European countries was 11.5% (15.3% in men and 8.6% in women). An inverse relation with level of education was observed among men, while no specific pattern was evident among women. Smoking prevalence was highest in eastern/central Europe for men (20.3%) and northern Europe for women (13.1%). In both sexes combined, smokers were more frequent in countries with low implementation of tobacco control activities (14.9%). Anti-tobacco campaigns and smoking cessation interventions specifically targeted to the elderly are urgently needed in Europe.

[Campaign against smoking in a home for the elderly: the report of an experiment]

Studies on institutionalized elderly smokers are important for developing appropriate preventive measures. This was a cross-sectional population-based study of individuals over 60 admitted to a Home for the Elderly in the Federal District. The following aspects were investigated: smoking prevalence, socio-demographic and clinical profile, gender, education, probable depression, degree of motivation to stop smoking, prior use of medication to stop smoking and perception of the harm of smoking to health. Spirometry, the measurement of exhaled carbon monoxide and classification according to severity of nicotine dependence were conducted. The program followed guidelines for stopping smoking, and was evaluated one year later. Results revealed that 25.7% were smokers, 22.8% men and 2.9% women, mean age 68.3 ± 8.5 years. A significant decrease in smoking among the more elderly was detected. Significant associations emerged between the degree of nicotine dependence and education, probable depression, degree of motivation for stopping smoking and perception of the harm of smoking to health. Higher indices of carbon monoxide were identified in individuals with severe obstruction. Initially, 37.9% of smokers agreed to participate in the campaign, and after a year 9% of them succeeded in stopping smoking.

[Evidence-based practices published in Brazil: identification and analysis studies about human health prevention]

Integrative review of Brazilian studies about evidence-based practices (EBP) about prevention in human health, published in Web of Science/JCR journals, between October 2010 and April 2011. The aim was to identify the specialties that most accomplished these studies, their foci and methodological approaches. Based on inclusion criteria, 84 studies were selected, mainly published in public health journals, focusing on primary care and also addressing clinical issues and different specialties. Prevention foci and methodological approaches also varied, with a predominance of systematic reviews without meta-analysis. The results indicate that there is no single way to conceptualize and practice EBP in the field of prevention, and that its application may not only serve to obtain indisputable evidence to equip intervention actions. This endless knowledge area is under construction, with a view to the analysis and further understanding of health phenomena.

Effects of cigarette smoking, metabolic syndrome and dehydroepiandrosterone deficiency on intima-media thickness and endothelial function in hypertensive postmenopausal women

Background

Cigarette smoking is a major risk factor of atherosclerosis. The aim of this study was to assess the relationship between smoking and arterial hypertension as well as endothelial dysfunction in postmenopausal women without clinically manifested symptoms of atherosclerosis.

Material/Methods

The study groups consisted of 35 current smokers and 45 nonsmokers. The thickness of intima-media complex (IMT), a marker of atherosclerosis, was measured in carotid arteries. Plasma concentrations of fasting glucose, insulin, lipoproteins, inflammatory markers (tumor necrosis factor-alpha, intercellular adhesion molecule-1), matrix metalloproteinases (metalloproteinase-9, tissue inhibitor of metalloproteinase-1), insulin, and dehydroepiandrosterone sulfate (DHEA-S) were measured.

Results

Smokers compared with nonsmokers showed lower fasting glucose levels in blood (87.0±10.9 and 93.2±13.6 mg/dl, p<0.05), higher mean systolic (131.1±15.9 vs. 123.0±10.9 mm Hg, p<0.05) and diastolic (81.7±11.4 vs. 75.2±9.2 mm Hg, p<0.05) blood pressure during daytime, and higher average heart rate during the daytime (78.2±9.3/min vs. 71.5±9.5/min, p<0.01) and at night (67.2±10.6/min vs. 61.7±7.7/min, p<0.05), respectively. The IMT in the right carotid artery was significantly higher in smokers than in nonsmokers (0.96±0.16 mm vs. 0.82±0.21, p<0.05) and was positively correlated with smoking intensity (R=0.36) and habit duration (R=0.35). The comparison of inflammatory markers, metalloproteinases, and DHEA-S concentrations in plasma did not reveal significant differences between the 2 groups. A significant negative correlation between DHEA-S concentration in plasma and IMT in right carotid artery was found in smokers.

Conclusions

Smoking in hypertensive postmenopausal women is associated with lower fasting blood glucose and BMI values, but higher arterial pressure and heart rate, and increases in IMT in right carotid artery.
