Prevalence of active and passive smoking during pregnancy: a cross-sectional study / Prevalência de tabagismo ativo e passivo durante a gravidez: estudo transversal

Purpose: The aim of the present study was to evaluate the prevalence of active and passive smoking during pregnancy and its association with sociodemographic indicators, as well as perinatal and postnatal outcomes in newborns. Methods: This cross-sectional study was comprised of 431 pairs of mothers/ newborns. The study variables were: preterm birth, birth weight, oral mucosal lesions, sociodemographic indicators and smoking data. We collected data from medical records and through a self-administered questionnaire answered by mothers. A pediatric dentist examined the newborns for oral mucosal lesions. Bivariate and multivariate logistic regression models were used to evaluate the association between active and passive smoking and the other variables (α=5%). Results: The prevalence of active (9.5%) and passive smoking (4.2%) during pregnancy was low. Active smoking was statistically associated with low birth weight (OR: 2.4; 95%CI:1.1-5.3), lower schooling level (OR: 0.2; 95%CI:0.1-0.5) and mothers aged ≥36 years old (OR: 4.9; 95%CI:1.2-20.0). Passive smoking was not statistically associated with the other variables. There was no association between active or passive smoking during pregnancy and premature birth and oral lesions of the newborn. Conclusions: The prevalence of active and passive smoking were low. Active smoking was associated with low birth weight, maternal age and mother's schooling, suggesting a social influence of smoking behavior among a population with a lower educational level. There was no association between active and passive smoking and prematurity and oral lesions of the newborn. (AU)

Objetivo: O objetivo do estudo foi avaliar a prevalência de tabagismo ativo e passivo durante a gestação e a associação entre indicadores sociodemográficos, bem como desfechos pré e pós-parto em recém-nascidos. Metodologia: Este estudo transversal foi composto por 431 pares de mães/recém-nascidos. As variáveis estudadas foram: nascimento prematuro, peso ao nascer, lesões mucosas orais, indicadores sociodemográficos e dados sobre tabagismo. Coletamos dados por meio de prontuários e por questionário auto-aplicado respondido pelas mães. Um dentista pediátrico examinou os recém-nascidos para lesões mucosas orais. A regressão logística foi utilizada para a análise bivariada e multivariada dos dados (α=5%). Resultados: Prevalência de tabagismo ativo (9,5%) e tabagismo passivo (4,2%) durante a gravidez foi baixo. O tabagismo ativo foi estatisticamente associado ao baixo peso ao nascer (OR: 2,4; 95%CI:1,1-5,3), às mães com menor escolaridade (OR: 0,2; 95%CI:0,1-0,5), e mães com idade ≥36 anos (OR: 4,9; 95%CI:1,2-20,0); enquanto o tabagismo passivo não esteve estatisticamente associado a nenhuma variável. Não houve associação entre tabagismo durante a gestação com nascimento prematuro e lesões orais de recém-nascidos. Conclusões: As prevalências de tabagismos passivo e ativo foram baixas. O tabagismo ativo esteve associado ao baixo peso ao nascer, à idade materna e à escolaridade da mãe, sugerindo influência social do comportamento do tabagismo entre a população com menor escolaridade. Não houve associação entre tabagismo ativo e passivo com prematuridade e lesões de mucosa oral em recém-nascido. (AU)

Prevalence of oral potentially malignant disorders associated with habits in Puducherry - a Cross-sectional study

Tobacco and betel quid are the most common cause of oral cancer in India. Very often oral cancers are preceded by a visible oral precursor lesion called as potentially malignant disorder (PMD). Aim: The aim of this study was to assess the prevalence of oral PMDs associated with habits in urban and rural areas of Puducherry Union territory, India. Methods: A cross-sectional descriptive study in urban and rural areas of Puducherry was conducted. The study group comprised of 450 patients with positive history of oral habits. A standard structured questionnaire was designed to record information about demographic details, socioeconomic status, type, duration and frequency of habits followed by clinical oral examination by single trained and calibrated examiner to detect the presence of PMD. Statistical analysis used: EpiData software (version 3.1). Descriptive statistics were presented for all variables. Pearson's Chi-Square test and adjusted odds ratio (ORs) with 95% confidence interval (CI) were calculated to estimate the suspected risk factors for PMD by using multivariate logistic regression analysis. P-value of ≤ 0.05 was considered to be statistically significant. Results: Prevalence of habit associated oral PMD was 64.2%. Females were more prone to develop PMDs (68.3%) as compared to males (62.8%). PMD was more common in the age group of 51-60 years (69.2%). Smoking with alcohol consumption was the most common oral habit. Habits, socio-economic status and diet were significantly associated with development of oral PMDs in our study population. Multivariate logistic regression analysis showed that chronic betel quid chewing and smoking were significant risk factors for PMD. Increased frequency of vegetable consumption reduced the risk of PMD. Conclusions: Oral PMD were observed in more than half of the subjects with oral habits in Puducherry. Clearly, there is an increased risk of PMD with increased duration of tobacco and betel quid use in this region. Patients and public need to be educated regarding PMD and encouraged to quit habits so as to prevent high risk population from developing cancer

The effects of sexual violence experienced in childhood and adolescence on undergraduate students / Os impactos da violência sexual vivida na infância e adolescência em universitários

ABSTRACT OBJECTIVE: This study aims to investigate the prevalence of adolescents and young adults who were victims of sexual violence at some point in their lives and to compare the presence of depressive and anxious symptoms, quality of life, and use of alcohol, tobacco, and illegal drugs among this population and those who were not abused. METHODS: Validated questionnaires and instruments were applied in a group of university students to assess: sexual profile and behavior, socioeconomic status, presence or not of sexual violence (Questionnaire on Exposure to Traumatizing Events), depressive (Beck Depression Inventory) and anxious symptoms (Beck Anxiety Inventory), quality of life (World Health Organization's Quality of Life Assessment) and the use or abuse of tobacco, alcohol, and illegal drugs (Smoking, Alcohol, and Substance Involvement Screening Test). RESULTS: Out of the 858 students who participated, 71 (8.3%) were victims of sexual violence, 52 girls (73.2%). In the victims of violence group there were more students who already had the first sexual intercourse (p = 0.029), students who already had become pregnant (p = 0.001), students with higher scores for depressive (p < 0.001) and anxious symptoms (p = 0.001), students with worse quality of life (p < 0.001), and who used more tobacco (p = 0.008) and marijuana (p = 0.025) as well as abused hypnotics or sedatives (p = 0.048) than in the non-victim group. CONCLUSION: The abuses are presented in several forms and affect, even in long term, the survivors' life. The sexual violence theme should be addressed and widely discussed in all spheres of society in order to mobilize, to sensitize, and provide society with knowledge, demystifying this subject and drawing attention to this important social issue.

RESUMO OBJETIVO: Investigar a prevalência de adolescentes e adultos jovens que foram vítimas de violência sexual em algum momento da vida e comparar a presença de sintomas depressivos e ansiosos, qualidade de vida e uso de álcool, tabaco e drogas ilícitas entre esta população e a que não sofreu abuso. MÉTODOS: Aplicaram-se questionários e instrumentos validados, em uma população de estudantes universitários, para avaliar: perfil e comportamento sexual, nível socioeconômico, presença ou não de violência sexual (Questionário sobre a Exposição a Eventos Traumatizantes), sintomas depressivos (Inventário de Depressão de Beck) e ansiosos (Inventário de Ansiedade de Beck), qualidade de vida (World Health Organization's Quality of Life Assessment) e o uso ou abuso de tabaco, álcool e drogas ilícitas (Teste para Triagem do Envolvimento com Fumo, Álcool e Outras Drogas). RESULTADOS: Dos 858 alunos que responderam à pesquisa, 71 (8,3%) foram vítimas de violência sexual, sendo 52 meninas (73,2%). No grupo vítima de abuso havia mais alunos que já tinham tido a coitarca (p = 0,029), alunas que já engravidaram (p = 0,001), estudantes com maiores escores para sintomas depressivos (p < 0,001) e ansiosos (p = 0,001), alunos com pior qualidade de vida (p < 0,001) e que usavam mais tabaco (p = 0,008) e maconha (p = 0,025) bem como abusavam de hipnóticos ou sedativos (p = 0,048) que no grupo não vítima. CONCLUSÃO: Os impactos causados pelo abuso são diversos e afetam, mesmo no longo prazo, a vida dos sobreviventes. Abordar o tema e o discutir, amplamente, em todas as esferas da sociedade é uma forma de mobilizar, sensibilizar e instrumentalizar o coletivo, desmistificando o assunto e chamando atenção para essa importante questão social.

Fresh Frozen Amniotic Membrane and Buccal Pad of Fat for Reconstruction of Oral Mucosal Defect After Surgical Excision of Leukoplakia

Objective: To compare the use of Fresh Frozen Amniotic Membrane (FFAM) and Buccal Pad of Fat (BPF) for reconstruction of oral mucosal defect after surgical excision of leukoplakia. Material and Methods: Twenty patients were randomly selected and divided into two groups. Group 1 use amniotic membrane graft and Group 2 BPF. Both groups were evaluated preoperatively and postoperatively. Incisal opening, epithelialization and fibrosis were evaluated after one month of surgery. Chi square and Student t tests were used. Results: According to the presence of smoking habits, the highest frequencies were for smoking (30%) and betel leaf areca nut with tobacco (30%). Regarding the diameter of oral leukoplakia, in 40% of the participants it was 2x3 cm2. In Group1, after one month of surgery preoperative and postoperative inter-incisal opening values were 44.20 ± 3.37 and 42.05 ± 3.47 (p<0.001). In Group 2, preoperative and postoperative inter-incisal opening values were 44.09 ± 3.32 and 43.01±3.38 (p>0.05). When FFAM was used complete epithelialization in 70% and incomplete epithelialization in 30% patients. When BPF was used the results were almost similar. Fibrosis occurred in 30% in Group 1. There were no complications like flap necrosis, infectiona and hematoma formation. Conclusion: Incisal opening was significantly better in Fresh Frozen Amniotic Membrane Group, epithelialization and fibrosis were almost same in both groups after surgical excision of oral leukoplakia.
