Objective: To evaluate changes in the levels of patient anxiety, depression, motivation, and stress over the course of smoking cessation treatment. Methods: This cohort study involved patients enrolled in a smoking cessation program in Cuiabá, Brazil. We selected patients who completed the program in six months or less (n = 142). Patient evaluations were conducted at enrollment (evaluation 1 [E1]); after 45 days of treatment with medication and cognitive-behavioral therapy (E2); and at the end of the six-month study period (E3). Patients were evaluated with a standardized questionnaire (to collect sociodemographic data and determine smoking status), as well as with the University of Rhode Island Change Assessment scale, Beck Anxiety Inventory, Beck Depression Inventory, and Lipp Inventory of Stress Symptoms for Adults. The data were analyzed with the nonparametric Wilcoxon test for paired comparisons. To compare treatment success (smoking cessation) with treatment failure, the test for two proportions was used. Results: Among the 142 patients evaluated, there were improvements, in terms of the levels of anxiety, depression, motivation, and stress, between E1 and E2, as well as between E1 and E3. In addition, treatment success correlated significantly with the levels of motivation and anxiety throughout the study period, whereas it correlated significantly with the level of depression only at E2 and E3. Conclusions: We conclude that there are in fact changes in the levels of patient anxiety, depression, motivation, and stress over the course of smoking cessation treatment. Those changes appear to be more pronounced in patients in whom the treatment succeeded.

Objective: Depression and anxiety have been documented in people with cystic fibrosis (CF), jeopardizing treatment adherence. To date, no studies have assessed the prevalence of psychosocial issues in adolescents with CF in Brazil. We sought to assess the prevalence of depression and anxiety in adolescents with CF in Brazil, as well as the impact of depression and anxiety on treatment adherence. Methods: This was a multicenter, prospective, observational, longitudinal study conducted between 2017 and 2019 at 14 CF referral centers in Brazil. We used standardized tools such as the nine-item Patient Health Questionnaire (for depression), the seven-item Generalized Anxiety Disorder scale (for anxiety), and the eight-item Morisky Medication Adherence Scale (for treatment adherence) in order to collect data on 218 CF patients at two different time points. Results: The prevalence of depression was 19.1% at time point 1 and 15.4% at time point 2. The prevalence of anxiety was 19.1% at time point 1 and 18.0% at time point 2. Depression and anxiety were significantly higher in female patients and lower in those who underwent home physiotherapy or had psychological support. Significant correlations were found between depression and anxiety at both time points, the associations being strongest at time point 1 (r = 0.68; p < 0.001). Most (66.7%) of the study participants reported low adherence to treatment, and the remainder reported either average adherence (in 28%) or high adherence (in 5.3%). Depression and anxiety showed inverse correlations with treatment adherence. Conclusions: The prevalence of depression and anxiety in adolescents with CF in Brazil appears to be similar to that reported in other countries, being higher in females and lower in those undergoing home physiotherapy or receiving psychological care. Depression and anxiety appear to correlate with lower treatment adherence. Treating psychosocial issues may effectively improve rates of treatment adherence in adolescents with CF.

Study objectives: Multidisciplinary pulmonary rehabilitation has been the most suitable treatment for chronic obstructive pulmonary disease (COPD). This clinical trial studied the prevalence of anxiety and depression and the effect of a pulmonary rehabilitation program on anxiety and depression levels of 46 COPD patients (mean ± SD age, 62 ± 11 years; 34 men and 12 women). Design: The participants underwent a 12-week treatment program: 24 sessions of physical exercise, 24 sessions of physiotherapy, 12 psychological sessions and three educational sessions. All patients were evaluated at baseline and at completion of the rehabilitation program through three instruments: Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and 6- minute walking distance (Tcam6'). Results: Patients demonstrated significant statistical improvements, including reduced anxiety and depression, and increased endurance: BAI 16.4 ± 6.9 vs. 6.8 ± 5.3 (p < 0.001); BDI: 16.9 ± 8.7 vs. 7.5 ± 6.6 (p < 0.001); Tcam6": 335.7 ± 83.4 vs. 441.6 ± 100.8 (p < 0.05). Conclusions: COPD patients presented high prevalence of anxiety and depression levels. The pulmonary rehabilitation program was able to improve patient exercise performance, and to reduce anxiety and depression levels.

Objective: To evaluate the presence and severity of symptoms of anxiety and depression in individuals with asthma or chronic obstructive pulmonary disease. Methods: In order to evaluate symptoms of anxiety and depression, specific instruments of quantification (the State-Trait Anxiety Inventory and the Beck Depression Inventory, respectively) were administered to patients at an outpatient clinic for the treatment of asthma and chronic obstructive pulmonary disease. The population comprised 189 randomly and prospectively selected patients that were divided into three study groups (each with a different therapeutic objective): 40 patients with controlled asthma, 100 patients with uncontrolled asthma, and 49 patients with chronic obstructive pulmonary disease. Included among the variables studied, as part of the methodology, were symptoms of anxiety and depression. The data obtained were compared taking into consideration demographic and functional aspects, as well as the severity of the symptoms of anxiety and depression. Results: Among the asthma patients, the prevalence of moderate or severe anxiety was significantly higher than that observed among those with chronic obstructive pulmonary disease (p <  0.001). The uncontrolled asthma group presented significantly higher rates of depressive symptoms than did the controlled asthma group (p < 0.05). Conclusion: The frequency of symptoms of anxiety and depression is greater among asthma patients than among patients with chronic obstructive pulmonary disease, which can make clinical control difficult.

Objective: To assess the 24-month effects of a pulmonary rehabilitation program (PRP) on anxiety, depression, quality of life and physical performance of COPD patients. Methods: Thirty patients with COPD (mean age, 60.8 ± 10 years; 70% males) participated in a 12-week PRP, which included 24 physical exercise sessions, 24 respiratory rehabilitation sessions, 12 psychotherapy sessions and 3 educational sessions. All patients were evaluated at baseline (pre-PRP), at the end of the treatment (post-PRP) and two years later (current) by means of four instruments: the Beck Anxiety Inventory; the Beck Depression Inventory; Saint George's Respiratory Questionnaire; and the six-minute walk test (6MWT). Results: The comparison between the pre-PRP and post-PRP values revealed a significant decrease in the levels of anxiety (pre-PRP: 10.7 ± 6.3; post-PRP: 5.5 ± 4.4; p = 0.0005) and depression (pre-PRP: 11.7 ± 6.8; post-PRP: 6.0 ± 5.8; p = 0.001), as well as significant improvements in the distance covered on the 6MWT (pre-PRP: 428.6 ± 75.0 m; post-PRP: 474.9 ± 86.3 m; p = 0.03) and the quality of life index (pre-PRP: 51.0 ± 15.9; post-PRP: 34.7 ± 15.1; p = 0.0001). There were no statistically significant differences between the post-PRP and current evaluation values. Conclusions: The benefits provided by the PRP in terms of the indices of anxiety, depression and quality of life, as well as the improved 6MWT performance, persisted throughout the 24-month study period.

Objective: To evaluate patient profiles and factors associated with successful treatment. Methods: A retrospective study of patients enrolled in the smoking cessation program at the Hospital de Messejana, located in the state of Ceará, Brazil, from October of 2002 to April of 2005. The treatment was evaluated based on patient profile, type of medication prescribed and time on that medication. Results: Of the 320 patients enrolled, 65.5% were women. The mean age at the outset of treatment was 48 years, and the mean duration of the smoking habit was 33 years. More than 90% of the patients had started smoking before the age of 20. Of the 258 individuals who had enrolled in the program at least one year prior, 50.8% had achieved treatment success; 17.8% had relapsed, and 31.4% had not quit smoking. On average, partial success was achieved in the fifth week of the treatment, and relapse occurred predominantly in the fourth month. Approximately 60% of the patients were treated with medication. Conclusion: Quitting smoking was significantly associated with the use of medication, regardless of the profile of the smoker evaluated. In the second year of the program, quitting smoking was more strongly associated with the use of bupropion and nicotine replacement, resulting in a higher success rate and a trend toward a reduction in the relapse rate.

Objective: There is evidence that asthma is associated with an increase in psychiatric symptoms and mental disorders. This association can make it difficult to achieve asthma control. The purpose of this study was to determine whether the level of asthma control is associated with anxiety and depression. Methods: A cross-sectional study involving 78 patients with confirmed moderate or severe asthma and under regular treatment at the Asthma Outpatient Clinic of the Federal University of São Paulo Hospital São Paulo, in the city of São Paulo, Brazil. The patients were divided into two groups by asthma control status, as assessed by the asthma control test, and were subsequently compared in terms of demographic, clinical, and spirometric data, as well as scores for asthma quality of life and hospital anxiety/depression. Results: The sample was predominantly female. Of the 78 patients, 49 (63%) were classified as having uncontrolled asthma. The prevalence of anxiety and of anxiety+depression was significantly higher among patients with uncontrolled asthma than among those with controlled asthma (78% and 100%; p = 0.04 and p = 0.02, respectively), whereas there were no differences between the two groups in terms of the prevalence of depression, spirometry results, or quality of life score. Conclusions: In this sample, the prevalence of anxiety symptoms was higher in the patients with uncontrolled asthma than in those with controlled asthma.In the evaluation of asthma patients, the negative impact of mood states ought to be taken into consideration when asthma control strategies are being outlined.

Objective: To analyze symptoms at different times of day in patients with COPD. Methods: This was a multicenter, cross-sectional observational study conducted at eight centers in Brazil. We evaluated morning, daytime, and nighttime symptoms in patients with stable COPD. Results: We included 593 patients under regular treatment, of whom 309 (52.1%) were male and 92 (15.5%) were active smokers. The mean age was 67.7 years, and the mean FEV1 was 49.4% of the predicted value. In comparison with the patients who had mild or moderate symptoms, the 183 (30.8%) with severe symptoms were less physically active (p = 0.002), had greater airflow limitation (p < 0.001), had more outpatient exacerbations (p = 0.002) and more inpatient exacerbations (p = 0.043), as well as scoring worse on specific instruments. The most common morning and nighttime symptoms were dyspnea (in 45.2% and 33.1%, respectively), cough (in 37.5% and 33.3%, respectively), and wheezing (in 24.4% and 27.0%, respectively). The intensity of daytime symptoms correlated strongly with that of morning symptoms (r = 0.65, p < 0.001) and that of nighttime symptoms (r = 0.60, p < 0.001), as well as with the COPD Assessment Test score (r = 0.62; p < 0.001), although it showed only a weak correlation with FEV1 (r = −0.205; p < 0.001). Conclusions: Dyspnea was more common in the morning than at night. Having morning or nighttime symptoms was associated with greater daytime symptom severity. Symptom intensity was strongly associated with poor quality of life and with the frequency of exacerbations, although it was weakly associated with airflow limitation.

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 evaluate changes in health-related quality of life (HRQoL) after twelve months of smoking cessation. Methods: This was a prospective study to evaluate the effectiveness of a smoking cessation program on the quality of life of 60 self-referred subjects, at a public hospital, during the period of August 2006 to December 2007. The program consisted of 2-h group sessions once a week during the first month and then every 15 days over six months, followed by monthly phone contacts for another six months. The treatment was based on behavior modification and the use of bupropion in combination with nicotinic replacement therapy. Abstinence was verified by exhaled CO measurements. Patient HRQoL was quantified using the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) questionnaire. Differences in quality of life scores between quitters and non-quitters at twelve months after the initial intervention were evaluated using analysis of covariance with baseline characteristics as covariates. Results: Self-reported quality of life scores were significantly higher among the 40 quitters than among the 20 non-quitters. The following SF-36 domains were most affected: role-emotional (p = 0.008); general health (p = 0.006); vitality (p < 0.001); and mental health (p = 0.002). At twelve months after the smoking cessation intervention, the SF-36 mental component and physical component summary scores were higher among quitters than among non-quitters (p = 0.004 and p = 0.001, respectively). Conclusions: Our findings illustrate that smoking abstinence is related to better HRQoL, especially in aspects of mental health.

Among all causes of preventable deaths, smoking is responsible for the greatest number of deaths worldwide and predisposes to fatal, noncommunicable diseases, especially cardiovascular diseases. Lifestyle changes are effective in the treatment of patients with smoking-related diseases and assist in the prevention of premature mortality. Our objective was to investigate the available scientific evidence regarding the psychological distress related to smoking cessation in patients who have had acute myocardial infarction. To that end, we conducted an integrative review of the literature in order to summarize relevant studies on this topic. The selected databases were Scopus, PubMed Central, Institute for Scientific Information Web of Science (Core Collection), ScienceDirect, EMBASE, SciELO, LILACS e PsycINFO. On the basis of the inclusion and exclusion criteria adopted for this study, 14 articles were selected for analysis. Those studies showed that the prevalence of psychological distress is higher among smokers than among nonsmokers, and distress-related symptoms are much more common in smokers with acute myocardial infarction than in those without. Smoking cessation depends on the active participation of the smoker, whose major motivation is the underlying disease. Most studies have shown that there is a need to create treatment subgroups as a means of improving the treatment provided. This review article expands the knowledge regarding smoking cessation and shows the need to invest in future research that investigates subgroups of smokers diagnosed with the major smoking-related comorbidities, such as acute myocardial infarction, in order to develop specific interventions and psychological support strategies.

Smoking is considered the leading preventable  cause of morbidity and mortality. The pharmacological management of nicotine withdrawal syndrome enables better cessation rates. In our smoking cessation program, we have developed a data collection system, which includes two new instruments: a score that assesses nicotine dependence in smokers of ≤ 10 cigarettes/day; and a patient comfort scale to be used during smoking cessation treatment. Here, we describe the two instruments, both of which are still undergoing validation.

Objective: To evaluate the effectiveness of a smoking cessation program, delivered by trained health care professionals, in patients hospitalized for acute respiratory disease (RD) or heart disease (HD). Methods: Of a total of 393 patients evaluated, we included 227 (146 and 81 active smokers hospitalized for HD and RD, respectively). All participants received smoking cessation treatment during hospitalization and were followed in a cognitive-behavioral smoking cessation program for six months after hospital discharge. Results: There were significant differences between the HD group and the RD group regarding participation in the cognitive-behavioral program after hospital discharge (13.0% vs. 35.8%; p = 0.003); smoking cessation at the end of follow-up (29% vs. 31%; p < 0.001); and the use of nicotine replacement therapy (3.4% vs. 33.3%; p < 0.001). No differences were found between the HD group and the RD group regarding the use of bupropion (11.0% vs. 12.3%; p = 0.92). Varenicline was used by only 0.7% of the patients in the HD group. Conclusions: In our sample, smoking cessation rates at six months after hospital discharge were higher among the patients with RD than among those with HD, as were treatment adherence rates. The implementation of smoking cessation programs for hospitalized patients with different diseases, delivered by the health care teams that treat these patients, is necessary for greater effectiveness in smoking cessation.

Introduction: Around one third of the world adult population smoke. Due to the recent researches on the smoking addiction and to the use of new drugs, the possibilities to succeed on the attempts to quit smoking have increased remarkably. Purposes: To study the tobacco abstinence in patients under treatment at the Ambulatório de Auxílio ao Abandono do Tabagismo da Pontifícia Universidade Católica do Rio Grande do Sul (AAAT-PUCRS) and to evaluate the role of some variables as risk factors to the chosen outcomes. Patients and methods: In a prospective open clinical trial not randomized we studied all the smokers who attended the AAAT-PUCRS within July 1999 and October 2000. All of them were submitted to the same standard program; the results were analyzed by central tendency measures for quantifying variables, relative risk with a IC95% for the associated factors and the Kaplan Meier's curve for the analyses of the time trend. Results: The study included 169 patients (67.5% women), average age 46 (± 10.4) years old; the most of them smoked 20 cigarettes/day for around 30 years. Even for a very young cohort like this one, it was possible to show that in relation to the outcome success/failure, 49% of the patients quit smoking, 14% remarkably diminished the number of smoked cigarettes and 37% failed completely. For the studied variables, severe dependency to nicotine was the only one associated with an increased risk to failure quitting smoking. Conclusions: It was possible to achieve a reasonable quitting smoking percentage adopting standard procedures described, but adapted for each patient. Pharmacological therapy was associated to a higher percentage of success.

Objective: To evaluate the efficacy of a mindfulness-based treatment (MBT) for smoking cessation or reduction and compare it with that of cognitive behavioral therapy (CBT). Methods: This was a single-center randomized controlled clinical trial including 113 patients divided into two groups: MBT (n = 54) and CBT (n = 59). The interventions comprised eight 90-min sessions. The primary outcome was smoking cessation at 16 weeks after program initiation. Secondary outcomes included reduction in the mean number of cigarettes smoked/day at 16 weeks after treatment initiation, as well as smoking cessation and reduction in the number of cigarettes smoked/day at the last program session. Participants had to attend = 50% of the sessions to be included in the primary outcome analysis. An intention-to-treat analysis was also performed. Results: There was no difference between the groups regarding the primary outcome (30.4% in the MBT group vs. 31.6% in the CBT group, p = 0.68) or immediate abstinence rates (47.8% in the MBT group vs. 36.8% in the CBT group, p = 0.47). Both treatments were equally effective in reducing the number of cigarettes smoked/day at the last program session (a reduction of 93.33% [0-100%] in the MBT group and of 70% [33.3-100%] in the CBT group, p = 0.92) and at 16 weeks after program initiation (a reduction of 57.1% [0-100%] in the MBT group and of 70% [25-100%] in the CBT group, p = 0.49). Conclusions: MBT appears to be as effective as CBT for smoking cessation or reduction and can be an option for the treatment of tobacco use disorders in Brazil (Brazilian Registry of Clinical Trials identifier: RBR-3w2scz [http://www.ensaiosclinicos.gov.br])

Objective: To compare smokers and never smokers in terms of the following: quality of life; BMI; hospitalizations; functionality; family history of mental disorder; tobacco-related diseases; depression; and psychoactive substance use. Methods: We evaluated 167 smokers enrolled in a smoking cessation program at the Londrina State University Referral Center for Understanding and Treating Smoking, together with 272 never-smoking blood donors. We employed the following instruments, all validated for use in Brazil: a structured questionnaire for the collection of sociodemographic data; the Alcohol, Smoking and Substance Involvement Screening Test; the World Health Organization Quality of Life Instrument, brief version (WHOQoL-BREF); and the Fagerström Test for Nicotine Dependence. We also applied diagnostic criteria for the investigation of depressive disorders. Results: The mean age of the smokers and never smokers was, respectively, 45 and 44 years. Females predominated in both groups. Smokers more often presented with impaired work/domestic functionality, hospitalizations, depressive disorders, smoking in the household, sedative use and a family history of mental disorders, as well as scoring lower in all domains of the WHOQoL-BREF. The mean age at smoking onset was lower for smokers with depression or using psychoactive substances than for smokers without such comorbidities. Diabetes, arterial hypertension, heart disease, respiratory disease and peptic ulcer were more common in smokers than in never smokers. The mean BMI was lower in the smokers than in the never smokers. Conclusions: This study suggests that, for smoking cessation programs, subgroups of smokers with specific characteristics (early age at smoking onset, tobacco-related diseases, depressive disorders and use of psychoactive substances) should be identified.

Objective: The impact of chronic obstructive pulmonary disease (COPD) is underestimation as a result of underdiagnosis and undertreatment. The objective of this study was to determine whether using spirometry to evaluate smokers enrolled in smoking cessation programs facilitates early diagnosis of COPD. Methods: The medical records of 158 smokers enrolled in the smoking cessation program at the Botucatu School of Medicine (Botucatu, Brazil) between January of 2003 and November of 2005 were evaluated retrospectively. All were over 40 years old (mean age: 55 ± 8.5 years), and 99 (62.6%) were female. We analyzed the clinical data, the previous medical diagnosis, and the spirometry results. Results: The diagnostic criteria for COPD were met by 57 (36.1%) of the 158 individuals evaluated, and 14 individuals (8.9%) were considered to be at risk for the development of the disease. Of those 57 individuals meeting the criteria for a diagnosis of COPD, 39 (68.4%) were receiving their first diagnosis of COPD, whereas 18 (31.6%) were receiving confirmation of a prior diagnosis. Of the 18 individuals previously diagnosed, 10 (56%) presented the mild/moderate form of the disease, and 8 (44%) presented the severe form. Of the 39 newly diagnosed individuals, 38 (97,4%) presented the mild/moderate for of the disease, and only 1 (2,6%) had severe COPD. Seven patients previously diagnosed with COPD presented pulmonary function test results inconsistent with the diagnostic criteria. Conclusion: Using spirometry in the initial evaluation of smokers enrolling in smoking cessation program might be a useful tool for early diagnosis of COPD.
