“…Studies have shown that asthma and bronchitis are associated with secondhand smoke in children, and that secondhand smoke children have an almost twice as high chance of presenting these respiratory problems (4,(7)(8)18) . The results of this study suggest that secondhand smoking in the home is also associated with the occurrence of treated ear disease in preschool children, corroborating previous studies (25)(26) . Considering these findings, some implications for the practice of health professionals deserve special attention.…”

Objective: Identifying the prevalence of secondhand smoking in the home and its association with morbidity and hospitalization from respiratory causes in preschool children. Method: This is a cross-sectional study conducted in five early childhood education centers at a public university in São Paulo. Sample size calculation was performed and the participants were randomly determined. Data were collected through questionnaires completed by family members or caregivers of 215 children. Chi-square and Student's t-test were used for the statistical analysis, using a 0.05 significance level. Results: The prevalence of secondhand smoke in the household was 15.3%. Bivariate analysis revealed that secondhand smoke in the household was associated with the occurrence of rapid breathing, subdiaphragmatic retractions in the past three months, and treated ear infections/otitis. Conclusion: A low prevalence of secondhand smoking in the home was found. Secondhand smoke was associated with a higher prevalence of respiratory symptoms and morbidity. DESCRIPTORS

“…A cross-sectional study of 115 children under 5 years of age in Botucatu (SP) showed that among 56 passive smokers, 27.7% had a cough, 18.3% chest wheezing and 17.4% otitis (25) . Secondhand smoking in the home was associated with respiratory symptoms of rapid breathing (22.6%) and retraction below the ribs (9.7%).…”

ResumoQuando as crianças são expostas ao tabaco são consideradas tabagistas passivos e podem apresentar complicações respiratórias frequentes. Este estudo teve como objetivo analisar a prevalência do tabagismo passivo em escolares e correlacioná-la com o nível socioeconômico dos pais/responsáveis, bem como avaliar a função pulmonar e força muscular respiratória das crianças tabagistas passivas. Primeiramente, os pais/responsáveis das crianças preencheram questionários sobre hábitos de fumar e status socioeconômico. Posteriormente, os alunos foram classificados como tabagistas passivos ou não expostos ao tabaco, e submetidos à avaliação fisioterapêutica, manovacuometria e espirometria. Desta forma o estudo foi realizado com 98 crianças, sendo 28,6% classificadas como tabagistas passivos, com presença de no mínimo um tabagista na família, e 71% não apresentaram exposição ao tabaco. O grupo dos tabagistas passivos apresentou a PImáx, CVF e Pico de fluxo expiratório significativamente menores quo o grupo não exposto ao tabaco. Conclui-se que foi elevada a prevalência do tabagismo passivo entre os escolares e baixo nível de escolaridade dos chefes das famílias do grupo tabagista passivo e ambos os grupos (tabagistas passivos e outro grupo de não expostas ao tabaco) apresentaram redução na capacidade vital forçada e pico de fluxo expiratório e aumento do índice de Tiffeneau, no entanto quando comparados, não apresentaram diferenças estatisticamente significativas. When children are exposed to tobacco, they are considered passive smokers and may have frequent respiratory complications. This study aimed to analyze the prevalence of passive smoking in schoolchildren and correlate it with the socioeconomic level of the parents / guardians, as well as to evaluate the lung function and respiratory muscle strength of passive smokers. First, the parents / guardians of the children filled out questionnaires about smoking habits and socioeconomic status. Subsequently, the students were classified as passive smokers or not exposed to tobacco, and submitted to a physical therapy evaluation, manovacuometry, and spirometry. In this way, the study was carried out with 98 children, 28.6% of whom were classified as passive smokers, with at least one smoker in the family, and 71% did not present tobacco exposure. The passive smokers' group had significantly lower MIP, FVC and peak expiratory flow than the group not exposed to tobacco. It was concluded that the prevalence of passive smoking among schoolchildren and the low level of schooling of the heads of the families of the passive smoking group was high. Both groups (passive smokers and the group not exposed to tobacco) presented a reduction in forced vital capacity, peak expiratory flow, and an increased Tiffeneau index; however, when compared, they did not present statistically significant differences.

Effects of passive inhalation of cigarette smoke on structural and functional parameters in the respiratory system of guinea pigs

Objective:To evaluate the effects of passive inhalation of cigarette smoke on the respiratory system of guinea pigs. Methods:Male guinea pigs were divided into two groups: control and passive smoking, the latter being exposed to the smoke of ten cigarettes for 20 min in the morning, afternoon and evening (30 cigarettes/day) for five days. After that period, inflammatory parameters were studied by quantifying mesenteric mast cell degranulation, as well as oxidative stress, in BAL fluid. In addition, we determined MIP, MEP, and mucociliary transport (in vivo), as well as tracheal contractility response (in vitro). Results:In comparison with the control group, the passive smoking group showed a significant increase in mast cell degranulation (19.75 ± 3.77% vs. 42.53 ± 0.42%; p < 0.001) and in the levels of reduced glutathione (293.9 ± 19.21 vs. 723.7 ± 67.43 nM/g of tissue; p < 0.05); as well as a significant reduction in mucociliary clearance (p < 0.05), which caused significant changes in pulmonary function (in MIP and MEP; p < 0.05 for both) and airway hyperreactivity. Conclusions:Passive inhalation of cigarette smoke caused significant increases in mast cell degranulation and oxidative stress. This inflammatory process seems to influence the decrease in mucociliary transport and to cause changes in pulmonary function, leading to tracheal hyperreactivity.
