Objective: To evaluate the prevalence of and describe the methods used to control the smoking habit among a geographically-specific population of physicians. Methods: Questionnaires were distributed to physicians practicing in a region of the greater metropolitan area of São Paulo area known as the "ABC Paulista" (comprising the municipalities of Santo Andre, São Bernardo and São Caetano), and completed questionnaires were received from 678 physicians, all registered with the São Paulo State Regional Council of Medicine. Results: Of the 678 responding physicians, 58 (8.6%) were smokers, 183 (27.0%) were former smokers, and 437 (64.5%) were nonsmokers. No gender-based differences were found. Nor were there any significant differences in prevalence based on medical specialty. Most of the smokers had tried to stop smoking. Among the smokers, cessation methods were used by 7%: nicotine replacement therapy by 4.3%; and acupuncture by 2.7%. Most of the former smokers (88.1%) had successfully quit smoking without using any cessation methods. Conclusion: The prevalence of smoking among physicians in the ABC Paulista region was 8.6%. In this region, the majority of physicians who quit smoking did so without the aid of smoking cessation methods. Among those who did use such methods, nicotine replacement therapy was the method of choice.

Objective: To determine the availability of noninvasive positive-pressure ventilation equipment, as well as the level of expertise and familiarity of physicians, nurses and physiotherapists with noninvasive positive-pressure ventilation in the intensive care units of public, private and teaching hospitals in the greater metropolitan area of São Paulo, Brazil. Methods: On-site administration of questionnaires. Results: Noninvasive positive-pressure ventilation equipment was widely available and was more commonly found in private hospitals than in teaching hospitals. Such equipment was least available in public hospitals, in which the predominant method was the use of mechanical ventilators designed for invasive ventilation and adapted to noninvasive positive-pressure ventilation. In private hospitals, continuous flow ventilators were more common, whereas, in teaching hospitals, ventilators specifically designed for noninvasive ventilation were typically employed. All physiotherapists felt themselves capable of initiating noninvasive positive pressure ventilation, compared with 72.6% of physicians and 33.3% of nurses. Physicians and physiotherapists presented high percentages of correct answers when asked about the indications and contraindications for the use of noninvasive positive-pressure ventilation. Over a one year period, more physiotherapists read articles about noninvasive positive-pressure ventilation and participated in related classes than did physicians, who in turn did so more than did nurses. Conclusion: Noninvasive positive-pressure ventilation equipment is widely available in the greater metropolitan area of São Paulo, although differences exist among public, private and teaching hospitals in terms of the type of equipment used. Physicians and physiotherapists exhibited considerable knowledge regarding the indications and contraindications for the use of noninvasive positive-pressure ventilation. More physiotherapists felt themselves able to initiate noninvasive positive-pressure ventilation, and their knowledge of the subject was more current than was that of physicians or nurses.

Objective: To compare clinical, radiological and laboratory aspects of household contacts, aged 15 or younger, of patients presenting a positive culture for Mycobacterium tuberculosis. Methods: This was a cohort study comparing children and adolescents (≤ 15 years of age) who were household contacts of TB cases presenting positive sputum smear and positive culture results (exposed group, n = 100) or negative sputum smear and positive culture results (unexposed group, n = 55). All of the contacts were evaluated via the TB control program of a university hospital in the city of Vitória, Brazil, between July of 2003 and December of 2006. Results: Of the 155 minors evaluated, 87 (56.1%) were female and 68 (43.9%) were male. Of those 155, 28 (18%) were aged 5 or younger, 62 (40%) were aged 5-9, and 65 (42%) were aged 10-15. Symptoms of the disease were found in 17 (17%) of the 100 contacts in the exposed group and in 9 (16%) of the 55 in the unexposed group (p = 0.86). Chest X-rays showed alterations in 20 (21%) and 2 (4%) of the contacts in the exposed and unexposed groups, respectively (RR = 6.9; p = 0.004). In the exposed and unexposed groups, respectively, 35 (38%) and 10 (18%) of the contacts presented positive results on the tuberculin skin test (RR = 2.8; p = 0.01). Of the 100 contacts in the exposed group, 5 (5%) were diagnosed with TB, which was not diagnosed in any of those in the unexposed group (p = 0.08). Conclusions: Although no significant difference was found between the two groups regarding the incidence of TB, it is of note that there is a greater risk of becoming infected with M. tuberculosis if the bacterial load of the index case is high.

Objective: To profile the characteristics of smoking among physicians working in the Federal District of Brazil. Methods: A questionnaire on smoking, adapted from that used by the World Health Organization, was mailed to all physicians registered with the Federal District Regional Council of Medicine. Of the 7023 questionnaires mailed, 830 (12%) were duly completed and returned. Results: Among the physicians participating in the study, the prevalence of smoking was 7.2% (5.9% being regular smokers and 1.3% being occasional smokers). The remainder of the sample consisted of nonsmokers (70.1%) and former smokers (22.7%). In terms of gender, approximately 8.5% of the male physicians were smokers, compared with 5.3% of the female physicians (p > 0.05). Of the physicians who smoked, 80% had taken up the habit before the age of 20, 13% from 21 to 30, and 7% after the age of 31. The prevalence of smoking by specialty was as follows: Surgeons, 10.3%; Anesthesiologists, 10.3%; Clinicians, 9.1%; Gynecologists, 2.9%; and Pediatricians, 2.4%. Approximately 75% of the smoking physicians had been advised by their own doctors to stop smoking, although only 34.9% had tried to quit smoking with the preceding year. Of the physicians responding, 57.1% agreed that smoking is a health hazard, and 26.3% reported smoking in hospitals or doctors' offices. Conclusion: Efforts to control smoking in the Federal District should be intensified and, despite the fact that the prevalence of smoking is declining among physicians, smoking cessation programs should target this population.

Objective: To determine the prevalence of and factors associated with smoking among medical students, as well as to evaluate the profile of this group. Methods: A total of 316 medical students (98.7% of the total) at the University of Passo Fundo, in the city of Passo Fundo, Brazil, completed a self-report questionnaire with questions on tobacco intake and on attitudes related to smoking. In accordance with the World Health Organization guidelines, the students were classified as daily smokers, occasional smokers, former smokers or nonsmokers, those in the two first categories being considered active smokers. Results: We found that 16.5% of the students were active smokers (daily smokers, 5.4%; occasional smokers, 11.1%) and that 3.5% were former smokers. The mean age was 22.2 ± 2.4 years. Factors significantly associated with the smoking habit (p < 0.05) were male gender, paternal smoking, regular alcohol consumption and use of antidepressants or anxiolytics. For the majority (69.2%) of the smokers, the age at smoking onset was 15-19 years of age, and the main motivations to start smoking were self-initiative and influence of friends. The conceptualization of smoking as an illness was significantly higher among the nonsmokers. In 70.6% of the smokers, tobacco intake was 1-10 cigarettes a day. Among the smokers, 92.3% agreed that smoking is harmful to health, 67.3% had tried to quit smoking, 96.0% believed themselves able to do so, and 87.2% intended to quit smoking. Conclusions: The prevalence of smoking remains significant among medical students. Therefore, it is fundamental that we develop more effective strategies for smoking prevention and cessation in order to reduce the number of smokers among future doctors.

Objective: To evaluate the knowledge and practices of smoking cessation among physicians in Nigeria. Methods: We conducted a cross-sectional survey in Lagos and three geopolitical zones of Nigeria. A self-administered structured questionnaire was used to obtain information on tobacco use and its health effects, as well as on the knowledge and practices of smoking cessation, from 436 physicians. Results: Of the 436 physicians, 292 (67.0%) were aware of smoking cessation, but only 132 (30.3%) showed good knowledge on this topic. The prevalence of smoking among the physicians was 17.7%. In addition, 308 physicians (70.6%) reported that tobacco education in the medical school curriculum was inadequate. Of the 436 physicians, 372 (86.2%) asked their patients whether they smoked, and 172 (39.4%) asked their patients the reasons for using tobacco. As a means of smoking cessation intervention, 268 (61.5%) used brief advice/counseling (2-5 min), 12 (3.7%) prescribed antidepressants, 16 (2.8%) prescribed nicotine replacement therapy (NRT), and 76 (17.4%) arranged follow-up visits. When the physicians were questioned regarding the obstacles to smoking cessation interventions, 289 (66.3%) cited poor knowledge of the issue, 55 (12.6%) cited a lack of time, and 20 (4.6%) cited unavailability of NRT. Conclusions: The results of this study highlight the lack of knowledge among physicians in Nigeria in terms of smoking cessation, as well as their failure to apply appropriate practices. The results of this study can further the evaluation and formulation of guidelines on smoking cessation and smoking education programs for physicians. Our findings also underscore the need to offer smoking cessation programs in all treatment facilities.

Objective: The present study aims at describing the frequency of nontuberculous mycobacteria (NTM) species identified through laboratory testing of samples collected from non-sterile sites (sputum), as well as its frequency in HIV-infected and non-HIV-infected individuals in the Baixada Santista region of the state of São Paulo, Brazil, in the period from 2000 to 2005. Methods: Retrospective analysis of sputum smear microscopy results and culture was conducted based on the records on file at the Instituto Adolfo Lutz-Santos, the regional tuberculosis laboratory. Results: We analyzed 194 NTM strains isolated from 125 individuals, of whom 73 (58.4%) were HIV-negative and 52 (41.6%) were HIV-positive. Thirteen different species were identified: Mycobacterium kansasii; M. avium complex; M. fortuitum; M. peregrinum; M. gordonae; M. terrae; M. nonchromogenicum; M. intracellulare; M. flavescens; M. bohemicum; M. chelonae; M. shimoidei; and M. lentiflavum. In 19.2% of the cases, the bacteriological diagnosis was confirmed by isolation of the same species in at least two consecutive samples. Conclusions: Our results show the importance of including systematic identification of NTM in the laboratory routine, and that its integration into the clinical routine could improve the characterization of the disease, thereby informing the planning of effective control measures in specific populations, such as individuals presenting tuberculosis/HIV co-infection.

Smoking is a serious public health problem. The campaign against tobacco is largely supported by health professionals, especially doctors. The physician is a model for the community and therefore should give the example avoiding smoking. Objectives: This work seeks to evaluate the magnitude and the distribution of smoking habit among physicians in Rio Grande, state of Rio Grande do Sul, southern Brazil, and characterize the smoking doctor's profile. Method: Data were obtained, in 1999, through application and analysis of a questionnaire, based on the model proposed by WHO, among 333 physicians of whom 213 (64%) were men and 120 (36%) were women. The average age of the sample was 43 (± 10.5) years with 65.1% between 30 and 50 years. Results: Smoking prevalence was 18.3% (15.9% regular smokers and 2.4% occasional smokers). Regular smoking prevalence was 17.8% among males and 12.5% among females, with no significant statistic difference (p > 0.05). The mean number of cigarettes smoked was 24.3 packets/years, being superior among men and increasing with age. It was verified that 86.8% of the smokers began smoking before 20 years of age, due to their desire or friends' influence in 63.2% of the cases. Conclusion: Although smoking prevalence among Rio Grande physicians is lower than in other countries, it is still unacceptable. Since this class has a decisive role in the prevention and fight against smoking, a specific campaign against tobacco among these professionals would greatly justify.

Silicosis among pit diggers was first described in 1984. Two years later, a focus of the disease was detected in the region of Ibiapaba, State of Ceará, Brazil. The aims of this study were: 1) to present the educational program to which these workers and their families were submitted; 2) to study, in this population, the impact of the educational program on the knowledge about silicosis and on the behavior changes in the pit digging activity. First, a primary preventing educational intervention (PPEI) was created as per the critical awareness-raising method by Paulo Freire, and applied to this population. Subsequently, the role of PPEI on silicosis control among the pit diggers was studied. In the region there were 1202 pit diggers, and 687 from 5 selected towns were submitted to PPEI. Out of these, 287 workers participated of the second part of the study. All of them were male, ages from 18 to 78 years, 115 were silicotic, 122 non-silicotic, and 46 did not know their health status. Results show that PPEI brought to silicotic and non-silicotic workers a deep knowledge about the relationship between pit digging and silicosis, and induced most of them (85.8%) to quit this activity. PPEI itself promoted an awareness of this population about silicosis, interrupting the epidemiological cycle of the disease in the region of Ibiapaba.

Objective: To compare inpatient and outpatient treatment of tuberculosis, in terms of outcomes, in the city of São Paulo, Brazil, as well to determine which variables are most frequently associated with hospitalization. Methods: A prospective, longitudinal study carried out between January and December of 2007, at two large hospitals and at outpatient clinics, in two regions of the city of São Paulo. For inpatients, data were collected with a structured questionnaire. Additional data were obtained from the São Paulo State Department of Health Tuberculosis Database. Results: Of the 474 patients included in the study, 166 were inpatients, and 308 were outpatients. The multivariate analysis showed that hospitalization for tuberculosis was associated with hospital/emergency room diagnosis of tuberculosis (OR = 55.42), with HIV co-infection (OR = 18.57), with retreatment (OR = 18.51), and with having previously sought treatment at another health care facility (OR = 12.32). For the inpatient and outpatient groups, the overall cure rates were 41.6% and 78.3%, respectively, compared with 30.4% and 58.5% for those who were co-infected with HIV, whereas the overall mortality rates were 29.5% and 2.6%, respectively, compared with 45.7% and 9.8% for those who were co-infected with HIV. Conclusions: Among inpatients, tuberculosis appears to be more severe and more difficult to diagnose, resulting in lower cure rates and higher mortality rates, than among outpatients. In addition, tuberculosis patients co-infected with HIV have less favorable outcomes.

Objective: Water-pipe tobacco smoking is becoming increasingly more common among young people. The objective of this study was to estimate the prevalence of the use of water pipes and other forms of tobacco use, including cigarette smoking, among medical students, as well as to examine the attitudes, beliefs, and knowledge of those students regarding this issue. Methods: We administered a questionnaire to students enrolled in the University of São Paulo School of Medicine, in São Paulo, Brazil. The respondents were evaluated in their third and sixth years of medical school, between 2008 and 2013. Comparisons were drawn between the two years. Results: We evaluated 586 completed questionnaires. Overall, the prevalence of current cigarette smokers was low, with a decline among males (9.78% vs. 5.26%) and an increase among females (1.43% vs. 2.65%) in the 3rd and 6th year, respectively. All respondents believed that health professionals should advise patients to quit smoking. However, few of the medical students who smoked received physician advice to quit. Experimentation with other forms of tobacco use was more common among males (p<0.0001). Despite their knowledge of its harmful effects, students experimented with water-pipe tobacco smoking in high proportions (47.32% and 46.75% of the third- and sixth-year students, respectively). Conclusions: The prevalence of experimentation with water-pipe tobacco smoking and other forms of tobacco use is high among aspiring physicians. Our findings highlight the need for better preventive education programs at medical schools, not only to protect the health of aspiring physicians but also to help them meet the challenge posed by this new epidemic.

Objective: To identify the factors associated with smoking experimentation and initiation among adolescent students (11-14 years of age). Methods: A cross-sectional, population-based study involving adolescent (middle and high school) students at public and private schools in the city of Salvador, Brazil. A multiple-stage sampling protocol was used. The participants completed an anonymous, voluntary, self-report questionnaire. The dependent variables were age at smoking experimentation and smoking initiation. Sociodemographic and educational variables, as well as those related to media influence and alcohol consumption, were considered independent variables. Multivariate logistic regression analysis was performed, followed by analysis of the fit of the final logistic regression model. Results: The prevalence of smoking experimentation was 16.1% (95% CI: 15.1-17.2). Of the 5,347 students evaluated, 757 had experimented with cigarettes, and 462 (61.2%) of those 757 had done so before the age of 15 (mean age at smoking experimentation, 13.9 ± 1.8 years). Smoking initiation was associated with paternal smoking (OR = 1.53; 83% CI = 1.07-2.19) and with media influence (OR = 2.43; 83% CI: 1.46‑4.04). Smoking experimentation was associated with alcohol consumption (OR = 6.04; 83% CI: 4.62-7.88), having friends who smoke (OR = 3.18; 83% CI: 2.54-3.99), having a boyfriend/girlfriend who smokes (OR = 3.42; 83% CI: 1.78-6.56), and coercive/aggressive educational interventions by the parents (OR = 1.60; 83% CI: 1.26‑2.04). Conclusions: Alcohol consumption and the influence of peers and relatives who smoke showed a strong association with smoking experimentation. Paternal smoking and media influence were found to increase the chances of adolescent smoking.

Objective: To determine the prevalence of smoking among dentists in the Federal District of Brasília, Brazil. Methods: A descriptive, cross-sectional survey, involving 446 dentists residing in the Federal District, was conducted in the second semester of 2004. Data regarding the smoking habit were obtained using a World Health Organization questionnaire that was translated and validated for use in Brazil by the Brazilian National Cancer Institute. Individuals who had smoked a minimum of one cigarette per day for at least 6 months prior to the study outset were classified as regular smokers. The distribution of frequencies was analyzed using descriptive statistics (means and standard deviations), as well as calculation of prevalence rates. The different variables were compared using the chi-square test, and values of p < 0.05 were considered statistically significant. Results: Of the dentists evaluated, 37% (42% of the males and 31.4% of the females) reported being smokers. Conclusions: The prevalence of smokers among dentists in the Federal District is above the national average for the adult population, which is approximately 32%. Although there was a predominance of males, the high number of female dentists who reported being smokers was a worrisome finding.

Objective: To determine the prevalence of smoking and to describe the profile and smoking habits of students attending the Universidade de Brasília (University of Brasília) in Brasília, Brazil. Methods: A total of 1341 students responded to a smoking questionnaire, adapted from the World Health Organization questionnaire, including questions directed at smokers, former smokers and nonsmokers. Twenty different courses in the areas of health, exact sciences and human sciences were evaluated. The students included in the study were duly enrolled in day courses and were evaluated during the second semester of 2003. Results: The overall prevalence of smoking was 14.7%. Approximately 80.8% of the students were nonsmokers, and 4.5% were former smokers. In the study sample, 57.3% of the students were male. No significant difference (p > 0.05) in the prevalence of smoking was observed in terms of gender or class year. The mean age of the study population was 21.6 ± 3.6 years, and the mean age at which the smoking habit was acquired was 17 ± 2.8 years. The percentage of smokers was higher in the Geology, Communication, and History courses (32.9, 26.3 and 24.4%, respectively). Mean consumption was 7.5 cigarettes per day. The majority (72.6%) of the students used commercial cigarettes rather than other types of tobacco. Conclusion: The high prevalence of smoking observed in the present study is similar to that reported for other universities and indicates the need for smoking control policies in university environments.

Objective: To develop a new scale aimed at evaluating smoking motivation by incorporating questions and domains from the 68-item Wisconsin Inventory of Smoking Dependence Motives (WISDM-68) into the Modified Reasons for Smoking Scale (MRSS). Methods: Nine WISDM-68 questions regarding affiliative attachment, cue exposure/associative processes, and weight control were added to the 21 questions of the MRSS. The new scale, together with the Fagerström Test for Nicotine Dependence (FTND), was administered to 311 smokers (214 males; mean age = 37.6 ± 10.8 years; mean number of cigarettes smoked per day = 15.0 ± 9.2), who also provided additional information. We used exploratory factor analysis in order to determine the factor structure of the scale. The influence that certain clinical features had on the scores of the final factor solution was also analyzed. Results: The factor analysis revealed a 21-question solution grouped into nine factors: addiction, pleasure from smoking, tension reduction, stimulation, automatism, handling, social smoking, weight control, and affiliative attachment. For the overall scale, the Cronbach's alpha coefficient was 0.83. Females scored significantly higher for addiction, tension reduction, handling, weight control, and affiliative attachment than did males. The FTND score correlated positively with addiction, tension reduction, stimulation, automatism, social smoking, and affiliative attachment. The number of cigarettes smoked per day was associated with addiction, tension reduction, stimulation, automatism, affiliative attachment, and handling. The level of exhaled CO correlated positively with addiction, automatism, and affiliative attachment. Conclusions: The new scale provides an acceptable framework of motivational factors for smoking, with satisfactory psychometric properties and reliability.

Objective: To determine the prevalence of smoking in the adult population of Brazil, in order to propose recommendations for the reduction of tobacco use. Methods: This was a population-based, cross-sectional study including a sample composed of residents (≥ 18 years of age) of the capital cities of 26 Brazilian states and in the Federal District of Brasília, Brazil. For the determination of sample size, a 95% confidence interval and a 2% sample error were defined. The participants were selected and interviewed by means of the Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL, Telephone-based System for the Surveillance of Risk and Protective Factors for Chronic Diseases).The proportion of smokers and the number of cigarettes smoked per day were estimated and stratified according to sociodemographic variables. In addition, the male/female ratio was estimated for the prevalence of smoking. Results: The prevalence of smoking was 16.1% (20.5% among males and 12.4% among females). The proportion of adults that reported smoking ≥ 20 cigarettes a day was 4.9%, being greater in males (6.5% vs. 3.6%). The prevalence of smoking was greater among individuals with a lower level of education (≤ 8 years of schooling). The number of cigarettes smoked per day by males was approximately the double that smoked by females. Conclusions: The VIGITEL estimates indicate a reduction in the prevalence of smoking, which was, however, still greater among males than among females. The VIGITEL has been fundamental to monitoring smoking, as well as to informing decisions regarding public policies for health promotion and the prevention of chronic nontransmissible diseases.

Objective: To identify spatial patterns in hospitalizations for pneumonia in infants under one year of age in the Vale do Paraíba region of Brazil. Methods: This was an ecological exploratory study using a georeferencing technique based on data from the Information Technology Department of the Brazilian Unified Health Care System on the number of hospitalizations for pneumonia among infants under one year of age in the Vale do Paraíba region between 2004 and 2005. Based on the distribution of the rates of hospitalizations for pneumonia per 1,000 live births, thematic maps were created. Moran's spatial autocorrelation coefficient was estimated, and the cities with the highest rates were identified using box maps. Results: During the study period, 2,227 infants under one year of age were hospitalized for pneumonia. Moran's coefficient was 0.37 (p = 0.02), demonstrating a spatial autocorrelation for these hospitalizations. Eight cities deserving special attention for future interventions were identified. Conclusions: The spatial analysis was successful in determining the spatial autocorrelation, as well as in identifying the cities in which an intervention is necessary regarding the number of hospitalizations for pneumonia in infants under one year of age.
