The associations between maternal smoking and nicotine dependence and patterns of smoking and nicotine dependence in offspring were examined in a large community-based sample of adolescents. Data were derived from baseline and 4-year follow-up assessments of 938 respondents aged 14–17 years at the outset of the Early Developmental Stages of Psychopathology (EDSP) study, a prospective-longitudinal community study of adolescents and young adults and their parents respectively. Smoking and nicotine dependence in respondents were assessed using the Munich Composite International Diagnostic Interview (DSM-IV algorithms). Diagnostic information about smoking behavior in mothers was collected by independent direct diagnostic interviews with the mothers. In comparison to children of non- or occasionally smoking mothers, children of regularly smoking and nicotine-dependent mothers had higher probabilities of using tobacco as well as of developing nicotine dependence. For all ages under consideration, survival analyses revealed a higher cumulative lifetime risk of regular smoking and nicotine dependence among these children. Maternal smoking during pregnancy seems to represent an additional risk for these outcomes in children, specifically with regard to the risk of developing nicotine dependence. Associations were comparable for sons and daughters. Our findings show that maternal smoking predicts escalation of smoking, development of nicotine dependence, and stability of smoking behavior in children. Implications for specific intervention and prevention efforts are discussed.

O tabagismo é um problema de saúde pública em todo o mundo. Entre as mulheres, devido ao aumento da prevalência comparada aos homens, o tabagismo feminino tem merecido atenção. Para o enfrentamento, é necessário entender o fenômeno e criar estratégias mais adequadas que incluam aspectos emocionais e sociais da dependência do tabagismo. Este estudo buscou descrever os esquemas cognitivos, sintomas de ansiedade e depressão de 112 mulheres que procuraram tratamento para cessação do tabagismo e sua relação com o insucesso do tratamento. A coleta de dados incluiu roteiro de entrevista estruturada e escalas validadas para a população brasileira que têm o objetivo de avaliar os esquemas cognitivos, sintomas de ansiedade e de depressão, e aspectos da dependência do cigarro. O conhecimento de fatores emocionais envolvidos no tabagismo e sua cessação podem ser úteis às ações de apoio à mudança comportamental do fumante. Objetivo: Descrever o perfil psicológico de mulheres que buscam cessação do tabagismo quanto aos esquemas cognitivos, sintomas de ansiedade e depressão antes e depois do tratamento com Terapia Cognitivo- Comportamental em grupo, e analisar fatores que contribuem para o desfecho de cessação. O desenho do estudo foi longitudinal e transversal. Para avaliar os esquemas cognitivos, o Questionário de Esquemas de Young em sua forma curta foi utilizado. Os grupos de terapia cognitivo-comportamental foram realizados concomitantes ao cuidado usual por médicos do estudo. Esses profissionais foram treinados no protocolo do estudo e o seguimento foi realizado por telefone por um membro do estudo independente e cego. Resultados: Os resultados forneceram evidências de que esquemas cognitivos tiveram relação significativa com os sintomas de depressão e ansiedade, com a adesão e os resultados do tratamento (cessação do tabagismo) / Cigarette smoking is a major public health problem worldwide. Among women, due to increased prevalence compared to men, the female smoking has deserved attention. To face, it is necessary to understand the phenomenon and create more appropriate strategies that include emotional and social aspects of smoking dependence. This study aimed to describe the cognitive schemes, symptoms of anxiety and depression of 112 women who sought treatment for smoking cessation and its relationship to treatment failure. Data collection included structured interview and validated scales for the Brazilian population who have to evaluate the cognitive schemes, symptoms of anxiety and depression and aspects of tobacco dependence. Knowledge of emotional factors involved in smoking and its cessation may be helpful to actions to support behavioral change of the smoker. Objective: To describe the psychological profile of women seeking smoking cessation regarding cognitive schemes, symptoms of anxiety and depression before and after treatment with cognitive-behavioral therapy in groups and analyze factors that contribute to the outcome of cessation . Method: The layout of the study was longitudinal and transversal. To assess the cognitive schemes, the Young Schema Questionnaire in its short form was used. The Cognitive Behavioral Therapy groups were conducted at the same time as the medical care and were applied by psychologists and medical doctors. These professionals were trained in the study protocol and the follow-up was conducted by telephone by the same independent and blind evaluator. Results: Our results provided evidence that the cognitive schemas of those women who sought treatment for quitting smoking showed a significant relation to the symptoms of depression and anxiety, with the adherence and the results of the treatment (quitting smoking), and with the positive impact of Cognitive Behavioral Therapy in decreasing schemas scores. It was also evident that the overall time throughout which the individual had smoked correlated to smaller rates of being able to quit smoking

Context: Tobacco use among medical students is of public health concern, given their role as future role models for healthy lifestyles. This study sought to determine the prevalence and determinants of tobacco use and nicotine dependence in medical students in Pretoria. In particular, this study explored the role of sense of coherence – a measure of stress-coping ability – on tobacco use patterns among medical students. Furthermore, we examined the students’ knowledge of smoking cessation approaches, their perceptions with regard to the availability and adequacy of tobacco control curricula, and their perception of their role as ”role models” for their patients. Methods: This cross-sectional analytical study, involving undergraduate medical students in their 2nd and 6th year of study at the universities of Pretoria and Limpopo (MEDUNSA), was conducted during August and September 2008. Consenting participants completed a self-administered questionnaire (N=722). Information obtained included: demographic characteristics of respondents, alcohol use, past and current use of various tobacco products, perception of availability and adequacy of training in tobacco control (TC), support for various TC legislation and perception of the role of doctors in smoking cessation. A six-item Antonovsky’s sense of coherence scale (SOC) was also included to measure respondents’ ability to cope with stress. Nicotine dependence was measured using the diagnostic and statistical manual of mental disorders, fourth edition (DSM-IV). Data analysis included chi-square statistics, t-test and multiple logistic regression analysis. Level of significance was set at p<0.05. Results: Prevalence of cigarette smoking in medical students was 17.3%. Cigarette smoking was significantly higher among the 6th (21.5%) than among the 2nd year (14.1%) students and was also significantly higher among males (20.4%) than among females (14.4%). In a bivariate analysis, problem drinkers were more likely to be smokers (37.5%) as compared to non-problem drinkers (13%). Compared to non-smokes, smokers were more likely to have a lower SOC [Mean(sd); 26.8 (8.8) vs 28.8 (7.4); p=0.019] and were less likely to attach importance to being seen as a role model by patients. Only 21.9% felt their training curriculum contained TC issues and of these a little over half felt the TC content was inadequate. After controlling for potential confounders, the factors that were independently associated with the current smoking status were, having lower support for TC legislation (OR=0.49; 95% CI= (0.41-0.59) and attaching less importance to being seen as a role model by patients (0.62; 0.41-0.91). Other factors associated with cigarette use included: being a 6th year student (OR=2.17; 95% CI; 1.32-3.58), having a drinking problem (2.17; 1.28-3.68), reporting exposure to others smoking at home (3.29; 1.91-5.66) and having received previous formal training in cessation (0.55; 0.32-0.95). Younger age (0.86; 0.77- 0.97), lower SOC (0.94; 0.90-0.99), and lower level of support for TC legislation (0.56; 0.40-0.79) were independently associated with nicotine dependence. Conclusions: This study’s findings suggest that tobacco use is prevalent among medical students and tobacco use is strongly associated with alcohol abuse. In addition to offering tobacco cessation services to these students, these findings highlight the need to institute a curriculum on tobacco control that includes not only teaching cessation counselling skills to medical students, but that also encourages them to become advocates for TC legislation and to recognise themselves as important role models in the society.

This paper describes the distribution of dependence criteria and diagnoses in a sample of 14- to 24-year-olds from Munich, Germany (n = 3,021; 71% response rate), evaluates differences between nondependent and dependent smokers and examines associations of smoking with other substances, affective and anxiety disorders. Assessment was made using the M-CIDI. The lifetime prevalence of DSM-IV nicotine dependence in the total sample is 19%, rising to 52% among regular smokers. No gender differences were seen in the progression from regular smoking to nicotine dependence, although men were more likely than women to initiate regular use. Analysis of daily cigarette use identified a significant dose-response relationship with the number of endorsed DSM-IV dependence criteria with unsuccessful cut-backs being the most prevalent criterion. As compared to nondependent smokers, dependent smokers were more likely to associate negative health effects with smoking and to have a desire to change and attempt a change in their pattern of use. Regular use of nicotine was found to be significantly associated with other substance and nonsubstance disorders, although dependent regular use was more strongly associated with these disorders than nondependent regular use. These results indicate that daily smoking is a behavior which is resistant to change despite an expressed desire and repeated cut-back attempts. Although initiation of regular smoking among nonsmokers does not occur frequently after the early twenties, the risk for dependent smoking among regular users persists into adulthood and is associated with a range of mental disorders.

Twin and family studies have shown that there is substantial evidence for a genetic component in the vulnerability to nicotine dependence (ND). The purpose of this study was to perform a meta-analysis on two genome-wide association (GWA) data involving 1079 cases of ND and 1341 controls in Caucasian populations. Through meta-analysis we identified 50 SNPs associated with ND with p<10-4. The best associated SNP rs7163369 (p=3.27×10-6) was located at 15q26 within SLCO3A1 gene while the second best SNP was rs9308631 (p=9.06×10-6) at 2q12.1 near ANAPC1. The third interesting locus rs688011 (p=1.08×10-5) was at 11q23.2 intergenic between NCAM1 and TCC12. Through meta-analysis, we found two additional ND associated genes ZCCHC14 (the top SNP was rs13334632, p=1.28×10-5) and KANK1 (the top SNP was rs13286166, p=1.49×10-5). The first top SNP rs7163369 within SLCO3A1 in the meta-analysis was replicated in the Australian twin-family study of 778 families (p=6.11×10-5) while SNP rs9653414 within ANAPC1 (p=4.61×10-5) in the meta-analysis was replicated in the family sample (p=9.31×10-4). Furthermore, rs2241617 in ZCCHC14 and rs4742225 in KANK1 showed strong associations with ND (p=1.06×10-7 and 4.81×10-7, respectively) in the replication sample. In addition, several SNPs of these loci (ANAPC1, KANK1, NACM1, TCC12, SLCO3A1 and ZCCHC14) were associated with alcohol dependence. In conclusion, we identified several loci associated with ND through meta-analysis of two GWA studies. These findings offer the potential for new insights into the pathogenesis of ND.

Os transtornos depressivos, a dependência de tabaco e os transtornos relacionados ao uso de álcool (TRUA) são altamente prevalentes e estão associados a diversas comorbidades. Todavia, permanecem subdiagnosticados e subtratados em diversos contextos de saúde. Dessa forma, o presente estudo teve por objetivos: a) avaliar parâmetros de fidedignidade e validade de instrumentos de rastreamento para transtornos depressivos (Patient Health Questionnaire - two itens [PHQ-2] e Well-Being Index - five itens [WHO-5]), dependência de tabaco (Fagerström Test for Nicotine Dependence [FTND] e Heaviness of Smoking Index [HSI]) e de álcool (Fast Alcohol Screening Test [FAST], CAGE, Alcohol Use Disorders Identification Test [AUDIT] e suas versões breves); b) realizar a análise fatorial do WHO-5, FTND e do AUDIT; c) avaliar a comorbidade entre os transtornos supracitados. Participaram dos estudos da fidedignidade teste-reteste 429 universitários e da fidedignidade interavaliadores 41 pacientes do Centro de Atenção Psicossocial - Álcool e Drogas (CAPS-AD). Os estudos da validade preditiva, consistência interna, comorbidade e análise fatorial utilizaram uma amostra de 530 pacientes do Pronto Socorro e do CAPS-AD. A fidedignidade foi estimada por meio do kappa e do coeficiente de correlação intraclasse (CCI). Nos estudos da validade preditiva, a SCID-CV foi a medida diagnóstica comparativa, sendo calculadas as áreas sob a curva ROC (ASC), sensibilidades, especificidades, acurácias, valores preditivos positivos e negativos dos instrumentos. A validade concorrente foi examinada pelo coeficiente de Spearman. O coeficiente alfa de cronbach foi utilizado para aferir a consistência interna. A análise fatorial exploratória foi realizada segundo os critérios de Kaiser. As comorbidades foram avaliadas por meio da regressão logística - odds ratios brutos e ajustados. O nível de significância foi de p<0,05, com intervalo de confiança de 95%. O PHQ-2 e do WHO-5 apresentaram altos índices de fidedignidade (>0,98). Exibiram, também, consistências internas elevadas (0,76 e 0,78, respectivamente). O WHO-5 obteve uma ASC de 0,89; sensibilidade de 0,85 e especificidade de 0,81 no ponto de corte nove. O PHQ-2 apresentou uma ASC de 0,86; sensibilidade de 0,74 e especificidade de 0,87 no ponto de corte três. O WHO-5 exibiu um único fator que explicou 51% da variância dos dados. Os estudos da fidedignidade do FTND resultaram em altos CCI (0,92 no teste-reteste e 0,99 no interavaliadores). Na análise fatorial, o FTND exibiu dois fatores. A consistência interna do FTND foi elevada (0,83), já a do HSI esteve abaixo do recomendado (0,56). O FTND e o HSI apresentaram elevados valores de sensibilidade, especificidade e acurácia. O AUDIT e suas versões abreviadas apresentaram consistências internas entre 0,83 e 0,94. No estudo da validade preditiva, esses instrumentos exibiram ASC entre 0,92 a 0,96, com índices de sensibilidade entre 0,84 e 0,93; e de especificidade de 0,83 a 0,94 para rastrear TRUA. A menor versão, o AUDIT-3 obteve excelentes resultados. No estudo da validade concorrente, observaram-se correlações expressivas entre as versões breves e o AUDIT (0,91 - 0,99). Em todas as avaliações o CAGE apresentou valores satisfatórios, porém inferiores aos das versões breves do AUDIT. Os resultados obtidos confirmam a validade e a confiabilidade das versões brasileiras do WHO-5, PHQ-2, FTND e do HSI, assim como, a eficácia de todas as versões breves do AUDIT, demonstrando que suas propriedades psicométricas são tão satisfatórias quanto às do instrumento completo e superiores as do CAGE. Portanto, o emprego desses instrumentos encontra apoio em sua viabilidade e sua validade, incentivando a sua utilização tanto na prática clínica diária como em pesquisas. Observou-se, neste estudo, que o tabagismo e o abuso e dependência do álcool são importantes preditores de transtornos depressivos e que os dependentes de álcool mostraram quatro vezes mais chance de serem tabagistas. / Depressive disorders, tobacco dependence, and alcohol-related disorders (ARD) are highly prevalent and are associated with several comorbidities. Nonetheless, they are still under-diagnosed and under-treated in many health settings. Therefore, this study was aimed at (1) assessing reliability and validity parameters of screening instruments for depressive disorders (Patient Health Questionnaire 2 [PHQ-2] and Well-Being Index 5 [WHO-5]), tobacco dependence (Fagerström Test for Nicotine Dependence [FTND] and Heaviness of Smoking Index [HSI]), and alcohol dependence (Fast Alcohol Screening Test [FAST], CAGE, Alcohol Use Disorders Identification Test [AUDIT] and their brief versions); (2) performing the factorial analysis of the WHO-5, FTND, and AUDIT; and (3) assessing the comorbidity between the above-mentioned disorders. The test-retest reliability study involved 429 university students and the inter-rater reliability study included 41 patients of a Center for Psychosocial Attention Alcohol and Drugs (CAPS-AD, in the Portuguese acronym). The assessment of the predictive validity, internal consistency, comorbidity, and factorial analysis involved a sample of 530 patients of an emergency unit and the CAPS-AD. Reliability was estimated by means of kappa and interclass correlation (ICC) coefficients. In the predictive validity studies, the SCID-CV was used as the comparison diagnostic measure, with calculation of the areas under the ROC curve (AUC), sensitivity, specificity, accuracy, and positive and negative predictive values of the instruments. Concurrent validity was assessed using Spearmans coefficient. Cronbachs alpha coefficient was used to assess internal consistency. The exploratory factorial analysis was conducted according to Kaisers criteria. Comorbidities were analyzed by logistic regression raw and adjusted odds ratio. The level of statistical significance was set at p < 0.05, with a 95% confidence interval. The PHQ-2 and WHO-5 had high levels of reliability (> 0.98) and internal consistency (0.76 and 0.78, respectively). The WHO-5 had an AUC of 0.89; sensitivity of 0.85; and specificity of 0.81 for a cut-off of 9. The PHQ-2 had an AUC of 0.86; sensitivity of 0.74; and specificity of 0.87 for a cut-off of 3. The WHO-5 yielded one single factor, which explained 51% of the data variance. The reliability study of the FTND provided high ICC coefficients (0.92 for test-retest and 0.99 for inter-rater). In the factorial analysis, the FTND yielded two factors. The internal consistency of the FTND was high (0.83), but that of the HIS was below recommended levels (0.56). The FTND and the HIS had high indices of sensitivity, specificity, and accuracy. The AUDIT and its brief versions had internal consistency values between 0.83 and 0.94. In the study of predictive validity, these instruments had AUC between 0.92 and 0.96, with sensitivity levels between 0.84 and 0.93 and specificity levels ranging from 0.83 and 0.94 for the screening of ARD. The shortest version of the AUDIT (AUDIT-3) had excellent results. In the assessment of concurrent validity, expressive correlations were found between the AUDIT and its brief versions (0.91-0.99). In all analyses, the CAGE had satisfactory results, although inferior to those of the brief versions of the AUDIT. The results confirm the validity and reliability of the Brazilian versions of the WHO-5, PHQ-2, FTND, and HIS, as well as the efficacy of all the brief versions of the AUDIT, demonstrating that their psychometric qualities are as satisfactory as those of the full version of the instrument and superior to those of the CAGE. Therefore, the use of these instruments is supported by their viability and validity, which encourage their use in routine clinical practice and research settings. The results also showed that smoking and alcohol abuse and dependence are important predictors of depressive disorders and that alcoholics had a fourfold higher chance of being smokers.
