The historical decline of tobacco smoking among United States physicians: 1949-1984

Prevalence and determinants of smoking behavior among physicians in emergency department: A national cross-sectional study in China

Objectives

To understand the current status of smoking behavior among emergency physicians in China and to explore its determinants.

Background

The emergency department is considered a more appropriate setting for tobacco interventions. However, the smoking behavior of emergency physicians can reduce the effectiveness of interventions for patient smoking behavior.

Methods

From July to August 2018, we conducted a structured online questionnaire among Chinese emergency medicine physicians. We used descriptive analysis with binary logistic regression to analyze the current smoking status of Chinese emergency physicians and its determinants.

Results

A total of 10,457 emergency physicians were included in this study. The prevalence of smoking among physicians was 25.35% (with 34.15 and 1.59% among male and female physicians, respectively). Results of logistic regression showed that postgraduate education (OR = 0.52, 95% CI: 0.41-0.66), chief-level title (OR = 0.79, 95% CI: 0.65-0.97), and regular exercise habits (OR = 0.83, 95% CI: 0.76-0.92) were associated with a lower risk of smoking behavior. However, being over 50 years old (OR = 1.71, 95% CI: 1.29-2.27), being fixed-term (OR = 1.25, 95% CI: 1.10-1.42), and having depressive symptoms (OR = 1.43, 95% CI: 1.28-1.61) were associated with a higher risk of smoking.

Conclusion

The prevalence of smoking behavior among emergency physicians in China is high. Hospital management could reduce the incidence of smoking behavior among emergency physicians by strengthening smoking cessation training, paying attention to physicians' psychological health, reducing pressure on physicians in fixed-term positions, and encouraging physicians to develop regular exercise habits.

Beliefs about harms of cigarette smoking among Norwegian adults born from 1899 to 1969. Do variations across education, smoking status and sex mirror the decline in smoking?

BACKGROUND AND AIM

Smoking is one of the most important causes of socioeconomic disparities in morbidity and mortality. The aim of this study was to examine if beliefs about harms of smoking differed across gender, smoking status and education among Norwegian adults born between 1899 and 1969.

METHODS

Using data from a nationally representative survey of smoking habits and a multinomial logit/negative binomial two-stage hurdle model design, we examined (first hurdle) the associations between birth cohort, gender, education and smoking status and four beliefs about cigarette smoking: i) smoking is not harmful, ii) do not know if smoking is harmful, iii) any number of cigarettes per day (CPD) is harmful and iv) smoking more than a given nonzero number of CPD is harmful, and (second hurdle) the predicted number of CPD that could be smoked without causing harm (from outcome iv).

RESULTS

The probability of believing that smoking was not harmful was close to zero, regardless of birth cohort, sex, education and smoking status. The probability of not knowing if smoking was harmful decreased from around 0.7 to almost zero across cohorts. The probability of believing that smoking more than zero CPD was harmful increased from less than 0.1 to around 0.7, while the probability of believing that there is some safe level of smoking increased with cohorts born from 1900 to 1930 before declining. Respondents with primary/secondary education consistently believed smoking to be less harmful compared to respondents with tertiary education, but cohort trajectories were similar.

DISCUSSION

The similar birth cohort trajectories in beliefs about the harms of smoking do not support the idea that Norwegian adults with lower education has had qualitatively different beliefs about the harmfulness of smoking compared to those with higher education. The persistent and large socioeconomic gradient is likely a result of other factors.

Prevalence of tobacco use in healthcare workers: A systematic review and meta-analysis

OBJECTIVES

To estimate tobacco use prevalence in healthcare workers (HCW) by country income level, occupation and sex, and compare the estimates with the prevalence in the general population.

METHODS

We systematically searched five databases; Medline, EMBASE, CINHAL Plus, CAB Abstracts, and LILACS for original studies published between 2000 and March 2016 without language restriction. All primary studies that reported tobacco use in any category of HCW were included. Study extraction and quality assessment were conducted independently by three reviewers, using a standardised data extraction and quality appraisal form. We performed random effect meta-analyses to obtain prevalence estimates by World Bank (WB) country income level, sex, and occupation. Data on prevalence of tobacco use in the general population were obtained from the World Health Organisation (WHO) Global Health Observatory website. The review protocol registration number on PROSPERO is CRD42016041231.

RESULTS

229 studies met our inclusion criteria, representing 457,415 HCW and 63 countries: 29 high-income countries (HIC), 21 upper-middle-income countries (UMIC), and 13 lower-middle-and-low-income countries (LMLIC). The overall pooled prevalence of tobacco use in HCW was 21%, 31% in males and 17% in females. Highest estimates were in male doctors in UMIC and LMLIC, 35% and 45%, and female nurses in HIC and UMIC, 21% and 25%. Heterogeneity was high (I2 > 90%). Country level comparison suggest that in HIC male HCW tend to have lower prevalence compared with males in the general population while in females the estimates were similar. Male and female HCW in UMIC and LMLIC tend to have similar or higher prevalence rates relative to their counterparts in the general population.

CONCLUSIONS

HCW continue to use tobacco at high rates. Tackling HCW tobacco use requires urgent action as they are at the front line for tackling tobacco use in their patients.

Cigarette smoking and smoking-attributable diseases among Estonian physicians: a cross-sectional study

Background

Smoking is a risk factor for several diseases. Physicians are role models for their patients. Physicians who smoke underestimate the health risks of smoking and may be less likely to offer advice to help their patients to quit. The aim of this study was to: provide an overview of smoking behaviour among Estonian physicians; assess the relationship between smoking and ischaemic heart disease (IHD), chronic bronchitis (CB), and lung emphysema (LE); and estimate fractions of prevalences of the three diseases attributable to smoking.

Methods

Self-administered questionnaires were sent to practising physicians (n = 5666) in Estonia in 2014. Prevalence of smoking and relative risks for IHD, CB and LE as well as the risks of IHD, CB and LE attributable to smoking were calculated by age and sex. Post-stratification was used to compensate non-response.

Results

There were 535 male and 2404 female physicians participating. The prevalence of daily smoking was 12.4% (95% CI 10.4–14.4%) among men and 5.0% (95% CI 4.4–5.6%) among women. Mean duration of smoking among male and female daily smokers was 28.6 (95% CI 26.1–31.1) and 28.6 (95% CI 27.1–30.2) years. Compared to lifelong non-smokers, the age-adjusted risk for IHD was 1.29 times (95% CI 0.88–1.89) higher for men, but 1.69 times (95% CI 1.17–2.40) lower for all women who have ever smoked. The risk for CB was 2.29 (95% CI 1.30–4.03) times higher for smokers among men and, 1.32 (95% CI 0.95–1.82) among women; the risk ratio for LE was 4.92 (95% CI 1.14–21.1) among men and 2.45 (95% CI 0.63–9.52) among women. The smoking-attributable risk for IHD was 3.2% (95% CI 2.3–4.1%) among men and − 0.1% (95% CI -0.7–0.4%) among women; for CB 6.9% (95% CI 6.0–7.8%) and 4.2% (95% CI 3.5–4.8%); and for LE 18.8% (95% CI 17.0–22.5%) and 22.6% (95% CI 18.5–26.9%), respectively.

Conclusion

Prevalence of daily smoking was relatively low among Estonian physicians (and twice lower among female physicians). The risk attributable to smoking was higher for LE and CB than for IHD.

Physicians' views on the role of smoking in smoking-related diseases: findings from cross-sectional studies from 1982-2014 in Estonia

Background

Previous reports have shown that physicians who smoke underestimate the effects of smoking on health and this influences their practice. This study was designed to investigate the views of Estonian physicians on the role of smoking in smoking-related diseases.

Methods

Cross-sectional postal surveys were sent to all practising physicians in Estonia in 1982, 2002 and 2014 providing data from 3504, 2694, and 2865 physicians respectively. Data analysis involved calculation of the prevalence of smoking with 95% confidence intervals and calculation of the prevalence of agreement with a causal role of smoking in ischaemic heart disease (IHD), lung cancer and chronic bronchitis. Logistic regression was used to analyse associations between agreement with the statements that smoking is a cause of IHD, lung cancer, chronic bronchitis and study year, smoking status, age group and ethnicity. Fully adjusted odds ratios with 95% confidence intervals were calculated.

Results

The age-standardized prevalence of current smoking among men decreased from 39.6% in 1982 to 14.2% in 2014, and among women from 12.4 to 5.1%, respectively. Compared with 1982, the proportion of physicians agreeing with statements that smoking is a major cause or one of the causes of IHD, lung cancer, or chronic bronchitis was significantly higher in 2002 and 2014. Past and never smokers were more likely to admit a causal role of smoking in lung cancer than smokers. Agreement with a causal role of smoking in IHD and chronic bronchitis was significantly higher among never and past smoking women only. Compared with non-Estonians, the odds ratio indicating agreement with all three statements was significantly higher among Estonians.

Conclusion

From 1982 to 2014, physicians’ attitudes towards the health risks of smoking improved in Estonia. However, their assessment of a causal role of smoking in smoking-related diseases was related to their own smoking habits and ethnicity.

A further decline in smoking among Estonian physicians would require special efforts targeted at physicians. Societal pressure from a national policy could support a further decline in the social acceptability of smoking in Estonia and developments in medical education could provide continuing evidence-based information about the effects of smoking to Estonian physicians.

Trends in smoking behaviour among Estonian physicians in 1982-2014

Background

Smoking surveys among physicians have proved useful in highlighting the importance of physicians as healthy life style exemplars and role models in tobacco control and smoking cessation. The aim of this study was to give an overview of smoking behaviour among Estonian physicians from 1982 to 2014.

Methods

Three cross-sectional postal surveys using a self-administered questionnaire were carried out among all practising physicians in Estonia. The number of physicians participating in this study was 3786 in 1982, 2735 in 2002, and 2902 in 2014. Data analysis involved calculating the age-standardized prevalences of smoking, prevalences of smoking by age group and mean age of smoking initiation. A non-parametric test for trend was used to assess significant changes in smoking over time.

Results

Age-standardized prevalence of current smoking among men was 39.7% in 1982, 20.9% in 2002, and 14.3% in 2014 and among women 12.2%, 8.0%, and 5.2%, respectively (p < 0.0001 for trends). From 1982 to 2014, the biggest decline of current smoking among men and women was in age groups under 35 (from 55.2% to 16.7% and from 16.7% to 2.8%, respectively) and 35–44 (from 47.1% to 8.3% and from 19.5% to 5.1%, respectively) (p < 0.0001 for trends). Mean age of smoking initiation decreased from 20.4 to 19.3 among men and from 24.5 to 20.4 among women over the study period.

Conclusions

In 1982–2014, smoking prevalence among Estonian physicians declined substantially. This may influence the willingness of society to recognize the health consequences of smoking which could give a support to the decline of the smoking epidemic in the country. Differences between smoking among male and female physicians persisted over the study period, but mean age of smoking initiation decreased. A further decline in smoking among Estonian physicians should be encouraged by special efforts targeted at physicians.

Dual diagnosis among physicians: a clinical perspective

Co-occurrence of mental disorders and substance use disorders (dual diagnosis) among doctors is a cause of serious concern due to its negative personal, professional, and social consequences. This work provides an overview of the prevalence of dual diagnosis among physicians, suggests a clinical etiological model to explain the development of dual diagnosis in doctors, and recommends some treatment strategies specifically for doctors. The most common presentation of dual diagnosis among doctors is the combination of alcohol use disorders and affective disorders. There are also high rates of self-medication with benzodiazepines, legal opiates, and amphetamines compared to the general population, and cannabis use disorders are increasing, mainly in young doctors. The prevalence of nicotine dependence varies from one country to another depending on the nature of public health policies. Emergency medicine physicians, psychiatrists, and anaesthesiologists are at higher risk for developing a substance use disorder compared with other doctors, perhaps because of their knowledge of and access to certain legal drugs. Two main pathways may lead doctors toward dual diagnosis: (a) the use of substances (often alcohol or self-prescribed drugs) as an unhealthy strategy to cope with their emotional or mental distress and (b) the use of substances for recreational or other purposes. In both cases, doctors tend to delay seeking help once a problem has been established, often for many years. Denial, minimization, and rationalization are common defense mechanisms, maybe because of the social stigma associated with mental or substance use disorders, the risk of losing employment/medical license, and a professional culture of perfectionism and denial of emotional needs or failures. Personal vulnerability interacts with these factors to increase the risk of a dual diagnosis developing in some individuals. When doctors with substance use disorders accept treatment in programs specifically designed for them (Physicians' Health Programs), they show better outcomes than the general population. However, physicians with dual diagnosis have more psychological distress and worse clinical prognosis than those with substance use disorders only. Future studies should contribute to a better comprehension of the risk and protective factors and the evidence-based treatment strategies for doctors with dual diagnosis.

Smoking behavior, attitudes, and cessation counseling among healthcare professionals in Armenia

BACKGROUND

Smoking cessation counseling by health professionals has been effective in increasing cessation rates. However, little is known about smoking cessation training and practices in transition countries with high smoking prevalence such as Armenia. This study identified smoking-related attitudes and behavior of physicians and nurses in a 500-bed hospital in Yerevan, Armenia, the largest cancer hospital in the country, and explored barriers to their effective participation in smoking cessation interventions.

METHODS

This study used mixed quantitative and qualitative methods. Trained interviewers conducted a survey with physicians and nurses using a 42-item self-administered questionnaire that assessed their smoking-related attitudes and behavior and smoking cessation counseling training. Four focus group discussions with hospital physicians and nurses explored barriers to effective smoking cessation interventions. The focus group sessions were audio-taped, transcribed, and analyzed.

RESULTS

The survey response rate was 58.5% (93/159) for physicians and 72.2% (122/169) for nurses. Smoking prevalence was almost five times higher in physicians compared to nurses (31.2% vs. 6.6%, p < 0.001). Non-smokers and ex-smokers had more positive attitudes toward the hospital's smoke-free policy compared to smokers (90.1% and 88.2% vs. 73.0%). About 42.6% of nurses and 26.9% of physicians reported having had formal training on smoking cessation methods. While both groups showed high support for routinely assisting patients to quit smoking, nurses more often than physicians considered health professionals as role models for patients.

CONCLUSIONS

This study was the first to explore differences in smoking-related attitudes and behavior among hospital physicians and nurses in Yerevan, Armenia. The study found substantial behavioral and attitudinal differences in these two groups. The study revealed a critical need for integrating cessation counseling training into Armenia's medical education. As nurses had more positive attitudes toward cessation counseling compared to physicians, and more often reported having cessation training, they are an untapped resource that could be more actively engaged in smoking cessation interventions in healthcare settings.

Declining rates of tobacco use in the Japanese medical profession, 1965-2009

Background

Although there has been a downward trend in smoking rates among medical doctors in recent years, rates have been higher among Japanese doctors when compared internationally.

Methods

We extensively reviewed all published English- and Japanese-language articles that reported the smoking rates of Japanese doctors.

Results

A total of 36 articles were examined, most of which had been conducted as postal surveys, usually by a national, prefectural, or local medical association. Sample sizes ranged from 17 to 11 773, and response rates ranged from 33% to 91%. National surveys conducted between 1965 and 2009 suggest that there has been a statistically significant (P < 0.0001) decline in smoking rates among Japanese doctors (from around 68% to 16% among males and from 19% to 5% among females).

Conclusions

Overall, the published data reveal a significant decline in smoking rates among Japanese doctors since 1965, especially among men. Although less than one-fifth of Japanese male doctors now smoke, more work needs to be done in tobacco control to help further reduce the burden of smoking, especially in medical schools.

Tobacco smoking among doctors in mainland China: a study from Shandong province and review of the literature

BACKGROUND

Tobacco control represents a key area in which doctors can make a significant positive impact on their patients' lives. Despite this fact, however, doctors in certain regions of China are known to smoke tobacco at rates similar to or even exceeding those seen within the general population.

OBJECTIVE

This study sought to investigate the smoking habits of doctors at a teaching hospital in Shandong province, as well as providing a brief review of smoking research that has been conducted among doctors elsewhere in China.

METHOD

An anonymous questionnaire survey was distributed to doctors working at a university teaching hospital in 2008, as part of a larger study of occupational health issues in the healthcare profession.

RESULTS

The overall smoking prevalence rate of doctors in this study was 36.3% with significant differences observed between the genders (males: 46.7% and females: 5.3%). Age and total career length were also correlated with smoking habit, although no significant associations were found with department of employment.

CONCLUSIONS

Overall, our study suggests that smoking rates among doctors in Shandong province are higher than those documented in many other countries, a finding which is consistent with previous research conducted in some other Chinese provinces. Addressing this issue from an intrinsic cultural perspective will clearly need to form the cornerstone of tobacco control efforts within the Chinese medical community in future years.

Smoking health professional student: an attitudinal challenge for health promotion?

Tobacco is a major preventable cause of premature morbidity and mortality. Health professionals are uniquely positioned to provide targeted interventions and should be empowered to provide cessation counselling that influence patient smoking. A cross-sectional national survey was administered to all third year students in four disciplines at the University of Malta. The Global Health Professional Student Survey (GHPSS) questionnaire was distributed to collect standardised demographic, smoking prevalence, behavioural, and attitudinal data. 81.9% completed the questionnaire (n = 173/211). A positive significant association between tobacco smoke exposure at home and current smoking status was identified. Non-smokers regarded anti-tobacco policies more favourably than smokers, being more likely to agree with banning of tobacco sales to adolescents (OR 3.6; 95% CI: 2.5–5.3; p ≤ 0.001); and with a smoking ban in all public places (OR 8.9; 95% CI: 6.1–13.1; p ≤ 0.001). Non-smokers favoured a role for health professionals in promoting smoking cessation (OR 5.1; 95% CI: 3.1–8.5; p ≤ 0.001). Knowledge of antidepressants as tools for smoking cessation was also associated with a perceived role for skilled health professionals in cessation counselling (OR 4.9; 95% CI: 1.8–13.3; p = 0.002). Smoking negatively influences beliefs and attitudes of students toward tobacco control. There is a need to adopt a standard undergraduate curriculum containing comprehensive tobacco prevention and cessation training to improve their effectiveness as role models.

Nursing education and beliefs towards tobacco cessation and control: a cross- sectional national survey (GHPSS) among nursing students in Greece

BACKGROUND

Within the healthcare system, nurses have the ability to influence their patients' smoking habits through counselling. Therefore, it is of great importance to appropriately train health professionals on smoking cessation strategies with the aim to help them provide advice to their patients. In light of the above, the objective of this study was to assess the association between Greek nursing students' beliefs towards tobacco control/smoking cessation and the professional training received.

METHODS

During February 2009, we conducted a cross sectional national survey among all 3rd year nursing students of the two university based nursing departments in Greece (University of Athens, University of the Peloponnese). The Global Health Professional Student Survey (GHPSS) questionnaire was applied and following written informed consent 73% provided a completed questionnaire (n = 192/263 enrolled students).

RESULTS

Overall, 33% were current active smokers, while 74% reported ever to experiment smoking. In regards to their beliefs towards tobacco control policies, non smokers were more positive in regards to banning smoking in restaurants (94% vs. 61%, p < 0.001), in bars and cafes (82% vs. 34%, p < 0.001), and all public places (93% vs. 51%, p < 0.001) when compared to current smokers. In comparison with students who had not received training on the importance of asking patients about their smoking habits, those that did were more likely to believe that nurses should have a role in smoking cessation and should act as role models for their patients.

CONCLUSIONS

Resources should be invested in improving the quality of undergraduate education in nursing departments in Greece with respect to tobacco control and smoking cessation.

Are Smoking Habits Changing among Spanish Health Professionals? Results from the SUN Cohort 1999–2008

Introduction

Smoking by health professionals is a very negative habit not only for their own health, but also because it diminishes their capacity to influence their smoker patients to quit their habits.

Objective

The aim of this study was to assess the trend of the smoking prevalence, as well as the impact of the 2005 Spanish Smoking Act, among healthcare professionals.

Methods

Participants were asked about their smoking consumption in the baseline and the follow-up questionnaires in a Spanish dynamic prospective cohort of university graduates (the SUN Project) from 1999 to 2008. Non-conditional logistic regression models were fit to assess the relationship between type of profession and prevalence of smoking.

Results

The proportion of current smokers at the entrance into the cohort was 16.4% for physicians, 20.8% for pharmacists, 23.4% for nurses and 24% for other university graduates. The risk of being current smoker (adjusted OR [95% CI]) was lower in physicians (0.68 [0.61–0.76]) but not in pharmacists (0.94 [0.84–1.06]) or nurses (0.94 [0.84–1.05]) compared to other university graduates. All professional groups presented a statistically significant decline of smoking prevalence from 1999 to 2008. This decline might be at least partly due to the impact of the Spanish legislation on their smoking habits.

Conclusion

This study shows a decline in smoking prevalence among Spanish physicians. This decline has reached lower levels than what is current among other professionals and the general population. However, there is still a high number of smokers among health professionals, thus more efforts are needed to achieve lower levels of tobacco consumption.

The historical decline of tobacco smoking among Australian physicians: 1964-1997

BACKGROUND

Physicians occupy an important position as tobacco control exemplars and their own smoking habits are known to influence how effective they may be in such a role.

METHODS

A comprehensive review of all published manuscripts describing tobacco usage rates and tobacco control activities in the Australian medical profession between 1964 and 1997.

RESULTS

Some of the earliest surveys revealed that around one-quarter of Australian physicians were smoking in the mid twentieth century, a rate which rapidly declined in the 1970s and 1980s, with reductions beyond that achieved by the general population.

CONCLUSION

Overall, our review suggests that not only do contemporary Australian physicians smoke at very low rates when compared internationally, but that an active professional community can also make a real difference to the lifestyle choices of its own members.
