A comparison of tobacco smoking among dentists in 15 countries

The Psychological Impact of the COVID-19 Pandemic on Dentists in Germany

Since the announcement of the coronavirus 2019 (COVID-19) outbreak as a pandemic, several studies reported increased psychological distress among healthcare workers. In this investigation, we examined the association between psychological outcomes and various factors among German dentists. Dentists from all German federal states were invited to participate in this study through a self-administered online questionnaire between July and November 2020. This questionnaire collected information on demographics, Depression Anxiety Stress Scales (DASS-21), and the Impact of Events Scale-Revised (IES-R) instrument. The associations displayed between demographic and psychological outcomes of depression, anxiety, stress, intrusion, avoidance, and hyperarousal were evaluated. Seven-hundred-and-thirty-two dentists participated in the survey and reported overall scores of (4.88 ± 4.85), (2.88 ± 3.57), (7.08 ± 5.04), (9.12 ± 8.44), (10.68 ± 8.88) and (10.35 ± 8.68) for depression, anxiety, stress, intrusion, avoidance, and hyperarousal, respectively. For females, being between 50-59 years of age, being immune deficient or chronically ill, working at a dental practice, and considering the COVID-19 pandemic a financial hazard were reported as significant associated factors (p < 0.05) with higher DASS-21 and IES-R scores. These findings underline the aspects which need to be taken into attention to protect the mental wellbeing of dentists in Germany during the crisis.

Prevalence of Ocular Injuries, Conjunctivitis and Musculoskeletal Disorders-Related Issues as Occupational Hazards Among Dental Practitioners in the City of Salem: A Randomized Cross-Sectional Study

Background:

Similar to several other occupations, dentists are also stricken by bounteous occupational health hazards (OHHs) such as musculoskeletal disorders (MSDs) and ocular health–related issues.

Aims:

The aim of this study was to evaluate the diffusion of MSDs and ocular health–related issues among dental surgeons in Salem city, Tamil Nadu, India, according to age, sex, and number of practicing hours per week.

Objectives:

A survey was conducted to examine the rate of prevalence of these OHHs amidst the dental surgeons in Salem city.

Materials and Methods:

The study was performed through a questionnaire amidst 150 dentists practicing in Salem City, Tamil Nadu, India. Dental surgeons were questioned about any occupational disorder that they had experienced related to a musculoskeletal pain and its location whether in the back, upper limbs, or lower limbs. In extension to this, dental surgeons were asked about any ocular injury that they had.

Results:

MSD showed higher rate of occurrence correlated to ocular health–related issues.

Conclusion:

The practice of protective measures is crucial, in perspective of the high rate of these disorders in the community of dental surgeons.

Musculoskeletal Disorders and Mental Health-related Issues as Occupational Hazards among Dental Practitioners in Salem City: A Cross-sectional Study

Background:

Like in any other profession, dental surgeons are also afflicted by many occupational health hazards such as Musculoskeletal disorders (MSD) and mental health related issues.

Aims:

To assess the distribution of MSD and mental health related issues amidst dentists in Salem City according to age, sex and number of working hours per week.

Objectives:

A survey was organized to check the rate of occurrence of these occupational health hazards among dental practitioners in Salem city.

Materials and Methods:

The study was conducted among one hundred and fifty dentists practicing in Salem City in the form of questionnaire. Dentists were asked about any occupational disease that they suffered related to a musculo–skeletal pain and its location whether in the back, upper limbs or lower limbs. In addition to this, dentists were asked about mental stress that they had experienced.

Results:

MSD showed higher rate of prevalence compared to mental health related issues.

Conclusion:

The application of preventive measures is necessary, in view of the high rate of these disorders in the society of dental practitioners.

Waterpipe Tobacco Smoking Among Dental Practitioners: Prevalence and Health Perceptions

BACKGROUND

Waterpipe tobacco smoking prevalence, practice, and the associated health perceptions among dental practitioners have not been previously reported. This study aims to determine the prevalence of waterpipe smoking among dental practitioners and to evaluate their awareness of health hazards of waterpipe smoking, particularly the adverse effects on oral health.

METHODS

This was a cross-sectional questionnaire-based survey among dental practitioners. Surveyed dental practitioners practiced dentistry in the holy city of Al-Madinah Al-Munawarah, a city in the Central-Western Region of Saudi Arabia, and the study was conducted during March 2015. The questionnaire consisted of questions on demographic data, history and practices of tobacco use, and perceptions toward the health hazards of smoking. Dentists were approached at their work places and invited to participate. Descriptive statistics were used to describe the sample’s demographic and smoking characteristics, while cross-tabulation and chi-square test were used to determine the statistical significance of association between the groups (P ≤ 0.05).

RESULTS

One hundred dental practitioners participated in the survey, with 55 males and 45 females. Twenty-six percent indicated that they were waterpipe smokers. Male gender and cigarette smoking were the only factors to be significantly associated with waterpipe smoking (P = 0.008 and P = 0.000, respectively). Most participants stated that waterpipe smoking is harmful to health, and the most commonly reported health hazard was respiratory disease, which was reported by 81% of participants.

CONCLUSIONS

Prevalence of waterpipe smoking among dental practitioners is comparable to adult populations but lower than younger populations of university students. Health awareness of dental practitioners regarding waterpipe smoking was judged to be insufficient.

General Practitioners and Dentists: A Call for Action Against Tobacco

INTRODUCTION

To investigate the frequency of advice to quit smoking received by the Italian population from general practitioners (GP) and dentists, we analyzed a cross-sectional study.

METHODS

A face-to-face survey was conducted in 2014 on 3052 individuals, representative of the general Italian population aged 15 years or more.

RESULTS

During the previous year, 89% of individuals (82% of smokers) reported that they had visited a GP while 71% (67% of smokers) had visited a dentist. Among smokers, 25% reported that they had received advice to quit smoking from their GP, and 26% from their dentist. Advice by GPs was less frequently received by smokers with higher education (multivariate odds ratios (OR) were 0.48 for intermediate and 0.38 for high as compared to low education), and more frequently by heavy smokers (≥15 cigarettes/day; OR = 1.78), those with intention to quit (OR = 2.59), with previous quit attempts (OR = 2.09), and those aware of the existence of smoking cessation services (OR = 1.59). Advice by dentists was more frequently received by smokers aged 25-44 years (OR = 3.55 compared to those aged 15-24) and those with an intention to quit (OR = 2.46). Among Italian current smokers, 32% reported that their GP and 17% that their dentist was a current smoker. The corresponding figures among young smokers were 40% and 26%, respectively.

CONCLUSION

Healthcare providers have the potential to become a key reference point in the fight against smoking. However, before acting, GPs and dentists should set a good example: those who smoke should urgently quit or at least refrain from smoking during working hours.

IMPLICATIONS

GPs and dentists, reaching the large majority of Italian smokers, can make a major contribution in the fight against tobacco. Future studies are needed to investigate possible reasons of the apparently high smoking prevalence among GPs, in order to develop tailored smoking cessation interventions for healthcare providers.

Smoking and attitudes towards it and its cessation among dental students in Latvia

BACKGROUND

The prevalence of smoking is higher in Latvia than in most EU countries. This study aimed to determine the level of knowledge of dental students in Latvia about the effects of smoking on oral health and their attitudes toward smoking and its cessation.

METHODS

A cross-sectional survey among all the dental students in Latvia was conducted in 2011. Students at the Riga Stradins University were asked to participate in this anonymous, voluntary survey. The questionnaire included items concerned with the students' own smoking habits, their knowledge of smoking as an addiction and its health effects and their attitudes towards its prevention and cessation in a dental setting. The response rate was 87% (173/200). The Chi-square test and logistic regression were used for the statistical analyses.

RESULTS

About one quarter of the students (24%) were daily or occasional smokers and almost half of the male students (46%) had smoked at least 100-times in their lifetime. The students revealed a lack of knowledge about the addictive nature of smoking, in that about half of the students did not consider smoking physically or socially addictive. About one fifth (21.4%) didn't consider environmental tobacco smoke (ETS) harmful to one's health. Although the students' awareness of smoking improved during their studies, the most significant factor related to their knowledge was their own smoking history (OR=2.7; p=0.021).

CONCLUSIONS

Smoking was frequent among undergraduate dental students and they lacked knowledge of its addictiveness. More emphasis ought to be placed on education with regard to smoking and on cessation services.

Determinants of preventive oral health behaviour among senior dental students in Nigeria

BACKGROUND

To study the association between oral health behaviour of senior dental students in Nigeria and their gender, age, knowledge of preventive care, and attitudes towards preventive dentistry.

METHODS

Questionnaires were administered to 179 senior dental students in the six dental schools in Nigeria. The questionnaire obtained information on age, gender, oral self-care, knowledge of preventive dental care and attitudes towards preventive dentistry. Attending a dental clinic for check-up by a dentist or a classmate within the last year was defined as preventive care use. Students who performed oral self-care and attended dental clinic for check-ups were noted to have complied with recommended oral self-care. Chi-square test and binary logistic regression models were used for statistical analyses.

RESULTS

More male respondents agreed that the use of fluoride toothpaste was more important than the tooth brushing technique for caries prevention (P < 0.001). While the use of dental floss was very low (7.3%), more females were more likely to report using dental floss (p=0.03). Older students were also more likely to comply with recommended oral self-care (p<0.001). In binary regression models, respondents who were younger (p=0.04) and those with higher knowledge of preventive dental care (p=0.008) were more likely to consume sugary snacks less than once a day.

CONCLUSION

Gender differences in the awareness of the superiority of using fluoridated toothpaste over brushing in caries prevention; and in the use of dental floss were observed. While older students were more likely to comply with recommended oral self-care measures, younger students with good knowledge of preventive dental care were more likely to consume sugary snacks less than once a day.

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.

Dentists' attitudes, behaviors, and barriers related to tobacco-use cessation in the dental setting

OBJECTIVE

This study assessed attitudes, behaviors, and barriers among general dentists in California, Pennsylvania, and West Virginia, related to patient tobacco cessation counseling.

METHODS

From 2004 to 2008, a baseline survey was mailed to 271 study dentists randomly selected from a master Delta Dental Insurance Company provider list in each state who had agreed to participate in a tobacco cessation randomized clinical trial. Four backward logistic regression models assessed correlates of the five As related to tobacco cessation: Asking about tobacco use, Advising users to quit, Assessing readiness to quit, Assisting with quitting, and Arranging follow-up.

RESULTS

Most respondents (n=265) were male, had practiced dentistry for over 15 years, asked about tobacco use (74%), and advised tobacco users to quit (78%). Only 19% assessed readiness to quit; 39% assisted with quitting; 4% arranged follow-up; and 42% had formal training in tobacco cessation. Believing that tobacco cessation counseling was an important professional responsibility, practicing <15 years, and asking about tobacco use significantly related to advising users to quit. Providing cessation advice and feeling effective intervening related to assessing readiness to quit. Advising users to quit, assessing readiness to quit, feeling effective intervening, and having had formal tobacco cessation training related to assisting with quitting. Barriers to cessation counseling were perceived patient resistance (66%), lack of insurance reimbursement (56%), not knowing where to refer (49%), and lack of time (32%).

CONCLUSION

Study dentists reported not fully performing the five As. Advising, assessing, having formal training, and feeling effective increased the likelihood of cessation counseling.

Setting a good example? Changes in smoking prevalence among key occupational groups in New Zealand: evidence from the 1981 and 2006 censuses

INTRODUCTION

Role modeling by smokers may influence smoking among children and young adults. Most work on smoking by occupation has focused on health workers. A unique opportunity to explore smoking by occupation is presented in New Zealand (NZ) due to inclusion of a smoking status question in most national censuses since 1976. Our aim was to assess trends in smoking prevalence among potential role model occupational groups in NZ.

METHODS

Adult smoking status by occupation was obtained from the 1981 census (N = 1,321,323) and 2006 census (N = 1,744,479). Subjects were aggregated into 5 broad groups of potential role-model occupations: teachers, uniformed services, health-related occupations, public figures, and sportspeople/entertainers. Age and sex-standardized current smoking prevalences were calculated using the 2006 NZ employed population as the reference standard.

RESULTS

Standardized smoking prevalence among the employed population was 34.5% in 1981 and had declined 37% in relative terms and 12.8% in absolute terms to 21.7% in 2006. Relative declines in smoking prevalence between 1981 and 2006 ranged from 35% to 60% among the role model occupational groups and absolute declines from 8.3% to 19.9%. Māori had higher smoking prevalence and lower relative declines in prevalence in each occupational group from 1981 to 2006, compared with non-Māori. Specific occupations mostly had low smoking prevalences--particularly doctors and teachers. But some role model occupations had high crude smoking prevalences in 2006 (up to 47%).

CONCLUSIONS

Persisting high smoking prevalence among some occupational groups suggest that additional targeted smoking cessation support for role model occupational groups may be justified.

The latest endangered species in Australia: a tobacco-smoking veterinarian

The results of a tobacco smoking survey conducted among veterinarians in Queensland, Australia, during 2007 are presented. Of the 567 participants only 3% reported being current smokers, 24% were ex-smokers and 73% had never smoked. The prevalence of smoking was similar among males and females, and the highest smoking rate was reported among veterinarians aged 31-40 years. However, the rate of never-smokers was strongly and negatively correlated with age, and the proportion of ex-smokers increased with age. Encouragingly, the results from this study suggest that tobacco use has all but disappeared from the Australian veterinary profession in recent years.

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 United States physicians: 1949-1984

Background

Tobacco use became an ingrained habit in the United States (US) following the First World War and a large proportion of physicians, similar to the general population, were smokers. The period from 1949 to 1984 was a pivotal era of change however, as the medical profession, like the society it served, became increasingly aware of the dangers that tobacco incurred for health.

Methods

An extensive review targeted all manuscripts published in academic journals between 1949 and 1984 that related to tobacco smoking among US physicians. The study was undertaken in 2007–08 with an internet search of relevant medical databases, after which time the reference lists of manuscripts were also examined to find additional articles.

Results

A total of 57 manuscripts met the inclusion criteria. From a research perspective, the methodology and coverage of smoking surveys ranged from detailed national investigations, to local medical association surveys, and journal readership questionnaires. From a historical perspective, it can be seen that by the 1950s many US physicians had begun questioning the safety of tobacco products, and by the 1960s and 1970s, this had resulted in a continuous decline in tobacco use. By the 1980s, few US physicians were still smoking, and many of their younger demographic had probably never smoked at all.

Conclusion

Although the quality and coverage of historical surveys varied over time, a review of their main results indicates a clear and consistent decline in tobacco use among US physicians between 1949 and 1984. Much can be learned from this pivotal era of public health, where the importance of scientific knowledge, professional leadership and social responsibility helped set positive examples in the fight against tobacco.

Self-reported occupational health issues among Lithuanian dentists

This article describes the second phase of a large study of Lithuanian dentists' health, and focuses on self-reported physical health complaints, general health state and associations between the two. In 2006, a postal questionnaire survey of all (N=2,449) licensed dentists registered with the Lithuanian Dental Association was conducted, obtaining a response rate of 68.2%. Fatigue (94.7%) and back pain (91.0%) were the most prevalent physical complaints reported, and they were also the most likely to become chronic among all physical disorders. Hypertension, joint diseases and allergy were the most prevalent diagnosed and treated diseases during the previous 12 months. Only half of the surveyed Lithuanian dentists (50.4%) rated their health as satisfactory. Logistic regression revealed that fatigue (Odds Ratio: 0.52; 95%CI: 0.29-0.94), headache (OR: 0.62; 95%CI: 0.42-0.90), hand problems (OR: 0.62; 95%CI: 0.44-0.87), chest pain (OR: 0.51; 95%CI: 0.40-0.64) and musculoskeletal complaints (OR: 0.41; 95%CI: 0.28-0.60) had a significant negative impact on dentists' self-reported general health. Overall, this study suggests that Lithuanian dentists do experience a certain amount of occupationally-related health problems. It is therefore important to increase health knowledge on occupational hazards and also to emphasize the importance of early diagnosis and treatment for these disorders in Lithuania, as elsewhere.

An international review of tobacco smoking among dental students in 19 countries

This study was conducted as a systematic review of all modern literature describing the prevalence of tobacco smoking among dental students. An electronic keyword search of appropriate terms was initially undertaken to identify relevant material, after which the reference lists of manuscripts were also examined to locate additional publications. A total of 27 studies from 19 countries were identified. The earliest manuscripts appeared in 1970, with the most recent being published in 2006. From a global perspective, our review suggests that tobacco smoking is relatively uncommon among contemporary dental students in Australia, Brazil, Canada, Great Britain and the United States. This is not surprising however, as it has previously been noted that dentists generally smoke at one of the lowest rates among all health professionals, and much lower than that of the communities in which they live. Somewhat discouragingly, we did find that smoking remains quite common among dental students in countries such as Greece, Serbia, Romania and Hungary. Given the fact that some of the student body continue to smoke tobacco, it is clear that more aggressive tobacco-specific measures should become a mandatory component of global dental education in future years.

Occupational health problems in modern dentistry: a review

Despite numerous technical advances in recent years, many occupational health problems still persist in modern dentistry. These include percutaneous exposure incidents (PEI); exposure to infectious diseases (including bioaerosols), radiation, dental materials, and noise; musculoskeletal disorders; dermatitis and respiratory disorders; eye injuries; and psychological problems. PEI remain a particular concern, as there is an almost constant risk of exposure to serious infectious agents. Strategies to minimise PEI and their consequences should continue to be employed, including sound infection control practices, continuing education and hepatitis B immunisation. As part of any infection control protocols, dentists should continue to utilise personal protective measures and appropriate sterilisation or other high-level disinfection techniques. Aside from biological hazards, dentists continue to suffer a high prevalence of musculoskeletal disorders (MSD), especially of the back, neck and shoulders. To fully understand the nature of these problems, further studies are needed to identify causative factors and other correlates of MSD. Continuing education and investigation of appropriate interventions to help reduce the prevalence of MSD and contact dermatitis are also needed. For these reasons, it is therefore important that dentists remain constantly informed regarding up-to-date measures on how to deal with newer technologies and dental materials.

An international review of tobacco smoking in the medical profession: 1974-2004

BACKGROUND

Tobacco smoking by physicians represents a contentious issue in public health, and regardless of what country it originates from, the need for accurate, historical data is paramount. As such, this article provides an international comparison of all modern literature describing the tobacco smoking habits of contemporary physicians.

METHODS

A keyword search of appropriate MeSH terms was initially undertaken to identify relevant material, after which the reference lists of manuscripts were also examined to locate further publications.

RESULTS

A total of 81 English-language studies published in the past 30 years met the inclusion criteria. Two distinct trends were evident. Firstly, most developed countries have shown a steady decline in physicians' smoking rates during recent years. On the other hand, physicians in some developed countries and newly-developing regions still appear to be smoking at high rates. The lowest smoking prevalence rates were consistently documented in the United States, Australia and the United Kingdom. Comparison with other health professionals suggests that fewer physicians smoke when compared to nurses, and sometimes less often than dentists.

CONCLUSION

Overall, this review suggests that while physicians' smoking habits appear to vary from region to region, they are not uniformly low when viewed from an international perspective. It is important that smoking in the medical profession declines in future years, so that physicians can remain at the forefront of anti-smoking programs and lead the way as public health exemplars in the 21st century.
