    Background
    The present study was designed to determine association passive smoking with dental caries and cotinine biomarker among 8-12 years old children of Semnan, Iran.
    Materials and Methods
    This cross sectional study was concocted on two groups of 8-12 years old children exposed (n=100) and non-exposed to passive smoking (n=100) in of Semnan (Iran). The sampling method was two-stage cluster sampling design. The data collection tool a standard checklist consisted of demographic, laboratory and dental characteristics. Examination was performed by a dentist on a dental unit and the dental indicators were measured for two groups. Also, salivary cotinine was measured and recorded using ELISA method by special cotinine kit (De salimetrics medi tec, USA). Univariate and Multivariable Logistic Regression model and area under the ROC curve were used to data analysis by STATA 14 software.
    Results
    Univariate logistic regression model showed a statistically significant difference between the exposed and unexposed groups with passive smoking in term of the salivary cotinine level, age , sex , decayed, missing, and filled teeth (dmft) index, decayed, and filled teeth (dft) index and missing teeth (mt) (P-Value ≤0.20). However, multiple logistic regression model showed a statistically significant relationship between the decayed, missing, and filled teeth (dmft) index and passive smoking (OR=1.28; 95% CI: 1.05 – 1.38).
    Conclusion
    This study showed that the risk of decay of deciduous teeth is higher in children exposed to passive smoking, therefore, passive smoking should be considered in the implementation of programs to prevent tooth decay in children.

    BACKGROUND AND AIM
    This study is conducted aiming to assess and compare the salivary levels of malondialdehyde (MDA) and lactate dehydrogenase (LDH) in active and passive smokers to determine the correlation between environmental tobacco smoke and health condition.
    METHODS
    This study evaluated 75 healthy individuals including 25 active smokers, 25 passive smokers, and 25 non-smokers with an equal percentage of males and females. Unstimulated saliva samples were collected from all participants. The salivary level of cotinine was first measured for correct allocation of participants to the aforementioned three groups using enzyme-linked immunosorbent assay (ELISA) technique. The salivary levels of MDA and LDH were then measured.
    RESULTS
    The salivary level of cotinine was 19.1, 8.12, and 3.36 nmol/ml in active smokers, passive smokers, and non-smokers, respectively. The salivary level of MDA was 4.78, 2.67, and 2.63 nmol/ml while the salivary level of LDH was 508.33, 364.98, and 271.63 nmol/ml in active smokers, passive smokers, and non-smokers, in the order given.
    CONCLUSION
    Acceding to the results, the salivary levels of cotinine, MDA, and LDH had significant correlations with cigarette smoking. The salivary levels of MDA and LDH were significantly higher in active smokers than passive smokers, and also the values in passive smokers were higher than the corresponding values in non-smokers (P < 0.05).

    Introduction

    One of the key aspects of mental health is one’s overall health and lifestyle. Longitudinal studieshave shown that dissatisfaction with life causes long-term health damage and increases mortality, suicide ten-dency, unintentional injuries, disability at work, and diseases such as those of cardiovascular nature. Amongstall forms of satisfaction, that of marital is of utmost importance. On a separate note, inhalation of cigarettesmoke exposes passive smokers to many chemical and toxic carcinogens, and it can negatively affect the non-smokers present. Furthermore, in psychiatric counseling sessions, many women report that they hate smoking.If we can show that inhaling cigarette smoke in men can have an impact on marital satisfaction, it can increasethe consistency of family foundations and have positive effects on the health and spirit of family members byinforming families.

    Methods

    In this study, 200 housewives, who had smoking husbands that smoked at home,were subjected to pre-determined conditions, alongside 200 housewives who had non-smoking husbands andwere therefore not exposed to smoking by their husbands at home. They were divided into two groups and wereassessed by Marital Conflict Questionnaire (MCQ). For a closer look at the level of marital satisfaction, the ques-tionnaire results were divided into three subgroups which were marked as low, moderate, and good.

    Results

    After calculating the total score of the questionnaire and statistical analysis, the results showed a higher rate ofmarital satisfaction in women who had non-smoking husbands compared to those who had smoking husbandsand this difference was considered significant at P-value <0.001.

    Conclusion

    Inhaling cigarette smoke in menin the family environment may seem to make a good impression on the smokers, but as the results of our studysuggest, it also has adverse effects on marital satisfaction.

    Statement of the Problem

    Smoking affects not only smokers themselves, but also the people around them. 700 million children are exposed to second hand tobacco worldwide. One of the adverse effects of being a passive smoker is oral pigmentation.

    Purpose

    Evaluating association between being a passive smoker and oral pigmentation.

    Materials and Method

    This is a historical cohort. 140 healthy children aged from 4 to 10 with the mean age of 6.68±1.60 years old (70 with a smoker parent and 70 without smoker parents) were examined for oral pigmentation. Environmental factors were evaluated by asking the parents to fill a questionnaire. Data were analyzed using Chi-square test, Fisher's exact test, Logistic regression and Spearman scale.

    Results

    There was a meaningful relationship between having a smoker parent and oral pigmentation (P-value=0.0001). spearman correlation showed parents' duration of cigarette smoking and the number of cigarettes per day meaningfully affect the severity of oral pigmentation (R=0.329). The study did not find a statistical relationship between oral pigmentation in passive smoking and sex or house area.

    Conclusion

    Children exposed to secondhand tobacco are at more risk for oral pigmentation. Its severity depends on duration of cigarette smoking and the number of cigarettes per day.

    Background

     There are many risk factors for childhood tinnitus such as hearing loss, exposure to high pitch sound, and passive smoking. Cotinine (C) is one of the metabolites of nicotine and is an important biochemical marker that reveals the objective and numerical indication of smoking exposure. Although there is a study investigating the role of urinary C levels in the etiology of tinnitus (T), the role of salivary C levels has not yet been elucidated.

    Objectives

     Therefore, this study aimed to investigate the risk factors of idiopathic subjective T in children in terms of passive smoking and whether the salivary C level can be used as a novel marker for monitoring and follow-up of T.

    Methods

     We retrospectively studied 1,245 children aged 7 - 15 years with T. We excluded 830 patients (66.5%) whose total tinnitus diagnosis was confirmed due to organic causes such as middle ear pathology and hearing loss. The remaining 415 (33.5%) patients with subjective T and 200 healthy individuals constituted the study and control groups. Complete blood counts, routine biochemical tests, and salivary C levels of children with T and controls were measured and their parents were also evaluated.

    Results

     In univariate analysis, parents’ C, children’s C, ALP, and erythrocyte levels were significantly associated with T (P < 0.001 in all). Regarding laboratory values, erythrocyte and serum ALP levels were significantly associated with T (P < 0.001 in both) in univariate analysis (OR, 0.99; 95% CI, 0.98 to 0.99 for erythrocyte and OR, 157.04; 95% CI, 44.7 to 551.6 for serum ALP level). No significant relationships were found between other parameters. These four parameters that were found to be significant in the univariate analysis showed meaningful associations with T in multivariate analysis (P < 0.01 for parents C and P < 0.001 for other parameters). It was also observed that as the C levels increased in the parents, the C level also increased in children.

    Conclusions

     There is a significant correlation between salivary C levels and parental salivary C levels in children. This suggests that the salivary C be used for evaluating the etiology of T in children and monitoring children with T exposed to cigarette smoke.

    BACKGROUND AND AIM

    Oral pigmentation is a condition in which the color of oral mucosa such as gingival mucosa changes. Some exogenous and endogenous factors may lead to oral pigmentation. Secondhand smoke (SHS) or environmental tobacco smoke (ETS) is indirect smoking of an active smoker’s exhalation that can lead to cardiovascular, respiratory system, and some oral diseases. The aim of this review study is to assess the effect of SHS on oral pigmentation.

    METHODS

    Data in this study were collected from PubMed, MEDLINE, and Scopus databases with the Medical Subject Headings (MeSH) keywords (Passive Smoking, Secondhand Smoke, Environmental Tobacco Smoke, Smoke Pollution, Involuntary Smoking, and Pigmentation) in the English language among the studies conducted in the period of 1990 to 2019. All records were imported into the EndNote software and duplicate articles were removed. The titles and abstracts of all records were pre-screened and among the articles remained, the relevant ones were selected for review based on the inclusion and exclusion criteria. To assess the quality of the studies, the Strengthening the Reporting Observational Studies in Epidemiology (STROBE) checklist was used.

    RESULTS

    Based on the STROBE checklist, the quality of the studies was assessed and finally, seven studies were included in the review, with six of them conducted about children and young adults and one about women. 6 (85.7%) articles showed a strong correlation between ETS and oral pigmentation and 1 (14.2%) showed no correlation.

    CONCLUSION

    ETS probably was correlated to the oral pigmentation.

    Background

    Passive smoking prevalence is high in Bangladesh. We aimed to explore the association of the theory of planned behavior constructs to reduce the exposure of passive smoking among children in the rural area of Bangladesh. Study Design: Cross-sectional study.

    Methods

    Overall, 410 adults had been taken at random following a self-administrative questionnaire. Data had been collected from six villages of Munshiganj district of Bangladesh from Jul to Oct 2018. Descriptive statistics were applied to describe socio-demographic characteristics. Inter correlations coefficient was done to observe the correlation, differences between demographic and dependent variables were assessed for significance using the Chi-square or Fisher’s exact test as appropriate. Univariate and multivariate logistic regression models were used to investigate the association between the theory of planned behavior constructs and exposure of passive smoking among both smoker and nonsmoker groups. All results were presented as unadjusted and adjusted odds ratio (OR) with 95% confidence intervals (CIs). A P-value ≤0.05 was considered as statistically significant.

    Results

    Attitude (OR 0.681, 95% CI: 0.498, 0.931) among smoker and intention (OR 0.226, 95% CI: 0.081, 0.633) was found statistically significant constructs (P<0.001) among non-smoker to reduce the exposure. Additionally, the prevalence of passive smoking exposure was found 36.6% (95% CI: 0.32%, 0.41%) on average 40% among males and 28.33% among females.

    Conclusion

    The theory of planned behavior constructs is useful to reduce the exposure of passive smoking among children, which may be useful in the future to design interventions of controlling passives smoking exposure.

    Background
     Smoking is one of the major factors that threatens human health. There is a controversy regarding the relationship between family members’ smoking behaviour and dental caries in children.  The purpose of this study was to evaluate the relationship between parents’ smoking behaviour and incidence of dental caries in their children who are considered passive smokers.
    Methods
     This study was conducted as a case-control method. 800 students within the age of 6 and 14 years old were randomly selected by sex and educational level. All the students were assessed in terms of the following factors: age; gender; educational level; school type; diet; frequency of tooth-brushing; frequency of parents’ smoking behaviour; number of smoker parents; number of teeth and general oral habits. This information was obtained through the questionnaires completed by parents. According to the World Health Organization (WHO) criteria, the Decayed, Missing and Filled Teeth index (DMFT/dmft) of the students were recorded by clinical examination through a disposable explorer and mirror  without radiography. The relationship between the studied variables was examined by Logistic regression method.
    Results
    Data of this research show that there is a significant relationship between the exposure time to the smoke and the dmft/ DMFT. It has been found that the longer exposure time since birth resulted in more DMFT / dmft changes (p=0.000).
    Conclusion
     The results of this study showed that parental smoking significantly affects the caries of deciduous and permanent teeth in their children.

    Background
    Exposure to smoking or passive smoking is one of serious health problems especially in the pediatric age group.
    Objectives
    To compare the prevalence and determinants of passive smoking in a nationally representative sample of Iranian children and adolescents according to their socioeconomic status (SES).
    Materials And Methods
    This nationwide study was conducted in 2011 - 2012 among 14880 students aged 6 - 18 years, living in 30 provinces in Iran. Exposure to the smoke of hookah or cigarette was documented by using validated questionnaires. Possible influencing factors were determined and the frequency of passive smoking was compared according to the regional and familial SES.
    Results
    Participants consisted of 13,486 children and adolescents including 49.2% girls and 75.6% urban inhabitants (90.6% participation rate). The mean age of participants was 12.47 ± 3.36 years. Overall, 43.87% of them (44.07% of boys and 43.66% of girls) were exposed to second hand smoke at home. Exposures to hookah or cigarette smoke at home were respectively reported in 21.46% and 34.49% of participants. The prevalence of passive smoking was lower in children of families with higher SES level, but higher in high SES regions of the country than in low SES ones, and ranged from 39.2% in the region with lowest SES to 49.05% in the highest SES region. Higher education levels of fathers and mothers were significantly associated with lower frequency of passive smoking.
    Conclusions
    Exposure to second hand smoke is a major problem among Iranian children and adolescents. Low family SES and low parental education increased the frequency of passive smoking. Appropriate public health education and legislation for smoke free home as well as family-centered counseling should be strengthened.

    Objectives
    Exposure to secondhand smoke (SHS) constitutes major health problems that threaten human health around the world; its adverse effects can lead to serious illnesses in both the pregnant women and the growing fetus. The purpose of this study was to determine the prevalence of SHS among Saudi pregnant women in King Khalid University Hospital (KKUH) and to determine the association between the socioeconomic characteristics of the pregnant women and exposure to SHS.
    Materials And Methods
    This was a cross-sectional study conducted in the antenatal clinic, KKUH. Data were collected from consecutive women using a predesigned questionnaire addressing the participants’ demographics and exposure to SHS status.
    Results
    The prevalence of SHS exposure among pregnant women was 24%. Low maternal education level and being unemployed were associated with more exposure to SHS (P = 0.039) and (P = 0.02), respectively. There was no association between maternal age, parity and monthly income and exposure to SHS (P = 0.697), (P = 0.420) and (P = 0.543), respectively.
    Conclusion
    Maternal educational levels and unemployment are associated risk factors for SHS exposure during pregnancy.

    Background
    Smoking is one of the major modifiable non-communicable disease risk factors. Our aim was to report the pattern of active and passive smoking using the data collected through a population base household survey in Kerman, Iran.
    Methods
    Given a cluster random sampling design, we recruited 5900 adult populations (15-75 years old) into a survey. After consenting, every participant was interviewed by a trained interviewer. The section for smoking had questions about daily (smoking at least one cigarette/day), non-daily, past and passive cigarette smoking as well as the time of exposure to cigarette’s smoke. We used Kerman population distribution (as the target population) to adjust our estimates using direct standardization method.
    Findings: Overall, 8.3% of study participants (15.5% in men vs. 0.8% in women, P = 0.010) reported themselves as daily smokers and 1.7% (2.9% in men vs. 0.4% in women, P = 0.010) as non-daily smokers. The passive smoking was common in total (27.5%), while women experienced more exposure than men (30.1% vs. 25.0%, P = 0.010). 3.2% of daily smokers smoked more than 20 cigarettes/day. Among passive smokers, 62.6% were exposed to cigarette smoke more than 6 days/week.
    Conclusion
    Smoking is pretty common among adult populations, particularly men. A majority of tobacco-free young adult women are exposed to passive smoking. Age and gender oriented interventions are required to change this risk pattern in our community to prevent from further smoking related morbidities and mortalities.

    سابقه و هدف
    به دنبال استعمال دخانیات به صورت passive یا active، اکسیدانها و آنتیاکسیدانهای متعددی تولید میشوند که عوارض متعددی بر سلامتی داشته، سیستم ایمنی فرد را تضعیف میکنند. همچنین، تولید رادیکالهای آزاد در استعمال دخانیات افزایش پیدا میکند. هدفاز این تحقیق، تعیین اثرات passive smoking بر ظرفیت تام آنتی اکسیدان بزاق و سرم موش صحرایی بود.
    مواد و روش ها
    در این مطالعه تجربی، 18 موش صحرایی با محدوده سنی11-7 هفته و وزن 200-160 گرم انتخاب و 9 راس از آنها روزانه 3 بار و هربار به مدت 8 دقیقه در معرض دود سیگارت قرار گرفتند. حیوانات کنترل (9 راس) در معرض دود سیگارت واقع نشدند. نمونه گیری سرم و بزاق از حیوانات گروه اکسپوژر و گروه کنترل در روزهای صفر، 15 و 30 پس از تزریق میدازولام (mg/kg 2/0) و پیلکارپین (mg/kg 5/0) انجام شد. کوتینین سرم نمونه ها با کیت الایزا تعیین و ظرفیت تام آنتیاکسیدان (TAC) بزاق و سرم با روش FRAP (ferric reducing acid antioxidant power) اندازهگیری شد. مقادیر TAC در زمانهای مختلف در هر گروه با آزمون آنالیز واریانس مقادیر تکراری و در میان دو گروه با آزمون t از نظر آماری مورد بررسی قرار گرفتند.
    یافته ها
    در ابتدای مطالعه، تفاوتهای معنی داری میان دو گروه از نظر مقادیر غلظت کوتینین سرم وجود نداشت ولی در روزهای 15 و 30؛ غلظت کوتینین در نمونه های گروه exposure به میزان آشکاری افزایش یافته بود. علاوه بر این، در روزهای صفر و 30، تفاوت معنی داری بین حیوانات دو گروه passive smoker و non-smoker از نظر مقادیر TAC سرم وجود نداشت ولی در روز 15مقادیرTACدر نمونه های گروه exposure به صورت معنی داری افزایش یافته بود. همچنین، مقادیرTAC در گروه passive smoker نسبت به گروه non smoker در روزهای صفر و 15 به صورت معنی داری بیشتر بود ولی در روز 30ام، تفاوت دو گروه از نظر آماری معنی دار نبود.
    نتیجه گیری
    براین اساس تغییرات ظرفیت تام آنتیاکسیدان بزاق و سرم حیوانات به دنبال قرار گرفتن در معرض دود سیگار توسط سیستم ایمنی حیوان تعدیل شده بود؛ هرچند همچنان به بررسی های بیشتر در این زمینه نیاز است

    Objective
    Active and passive smoking lead to the production of a number of oxidants and antioxidants with various adverse health effects compromising the immune system. Tobacco use increases the production of free radicals as well. The purpose of this study was to determine the effects of passive smoking on total antioxidant capacity (TAC) of serum and saliva in rats.
    Methods
    This experimental study was conducted on 18 rats with an age range of 7-11 weeks weighing 160-200 g; 9 of them were exposed to cigarette smoke 3 times daily for 8 minutes. The 9 controls were not exposed to cigarette smoke. After injection of 0.2 mg/kg midazolam and 0.5 mg/kg pilocarpine, serum and saliva samples were taken from subjects in the exposure and control groups at 0, 15 and 30 days. Serum cotinine was measured using ELISA kit. TAC of saliva and serum was measured using ferric reducing antioxidant power (FRAP) assay. TAC values at different time points were statistically analyzed in each group using Repeated Measures ANOVA and compared between the two groups using t-test.
    Results
    At baseline, no significant difference existed between the two groups in terms of serum cotinine concentration but at days 15 and 30, cotinine serum concentration significantly increased in the exposure group. At baseline and 30 days, no significant difference existed between the two groups of passive smoker and non-smoker in terms of serum TAC values but at day 15, serum TAC values were significantly higher in the exposure group. Also, TAC of salivawas significantly higher in the passive smoker group at baseline and at day 15 but at day 30, the difference in this respect between the two groups was not statistically significant.
    Conclusion
    Based on the obtained results, changes in TAC of serum and saliva in rats due to exposure to cigarette smoke were compensated by their immune system activity. However, further investigations are still required in this respect.

    Objective
    Exposure to environmental tobacco smoke (ETS) is one of the major factors of predisposing children to develop several hazardous health problems. We decided to investigate the association between nicotinine, one of the nicotine metabolites and esophagitis in children with gastroesophageal reflux disease (GERD).
    Methods
    In a case control study 46 children suffering from esophagitis referred to endoscopy ward were recruited. The control group consisted of 45 healthy children. Urine samples were collected and urinary cotinine level (UCL) measured.
    Findings
    The mean age of esophagitis and control groups were 5.11±2.93 and 6.72±2.8 respectively. Sixty children were passive smokers; 31 of them had non-smoker parents. In control group, 32 (71.1%) children and in esophagitis group 29 (63%) children had non-smoker parents. The mean value of UCL in patients suffering from esophagitis was significantly higher than those in normal group (P=0.04, 24.98±6.4 ng/ml vs. 15.16 ± 3.9 ng/ml). Considering 50ng/ml as a cutoff point for UCL, it was significantly higher in passive smoker group than in non smoker group (P=0.02). The mean cotinine level differed significantly in esophagitis and control group.
    Conclusion
    Our results indicate the increased risk of developing esophagitis in children with ETS exposure.

    Objective
    Many diseases form their basis during childhood. One example is the changes in vascular structure and function, leading to atherosclerosis. In this study, we have assessed the impact of exposure to cigarette smoke on blood pressure of elementary school children of Kermanshah.
    Methods
    80 elementary school children exposed to cigarette smoke and 80 not exposed to smoke were studied in fall 2010. Information regarding the smoking status of parents and the children’s health were obtained through questionnaires completed by parents. After physical examination and exclusion of those children with acute and chronic diseases as well as those consuming medicine, we measured and compared blood pressure in the exposure and non-exposure groups. Data were analyzed using the ANOVA statistical test. Values are expresses as Mean±SD.
    Findings
    The mean systolic and diastolic blood pressures of the exposure group were higher than those of the non-exposure group (109.3±9.97 /64.92±7.36 vs105.47±8.98/62.5±7.01, respectively; CI: 0.95, p<0.5).
    Conclusion
    Our study indicates that systolic and diastolic blood pressures are higher in those elementary school children exposed to cigarette smoke compared to those who are not.

    مقدمه و هدف
    قرار گرفتن در معرض دود سیگار منجر به عوارض سوء در سیستم تنفسی بخصوص درگروه سنی کودکان می شود. این مطالعه به تعیین رابطهمشکلات و عوارض سیستم تنفسی در کودکانی که مواجهه غیر ارادی با دود سیگارداشته وتحت بیهوشی عمومی قرار گرفته اند می پردازد.
    روش کار
    این مطالعه از نوع مورد شاهدی دوسو کور بود که در آن 223 کودک که کاندید بیهوشی عمومی بوده اند انتخاب گردیدند. 81 نفر که در معرض دود سیگار قرار داشتند در گروه مورد و 142 نفر که مواجهه غیر ارادی با دود سیگار نداشتند در گروه شاهد قرار گرفتند. عوارض تنفسی در حین و پس از بیهوشی عمومی توسط متخصص بیهوشی که از سابقه مواجهه با دود سیگار بی اطلاع بود ثبت گردید. سابقه مواجهه با دود سیگار توسط مصاحبه با والدین بیمار تهیه و ثبت گردید. اطلاعات بدست آمده با استفاده از آزمون آماری c2 آنالیز گردید.
    نتایج
    میانگین مواجهه غیر ارادی کودکان با دود سیگار 46/28 نخ سیگار در روز و بطور متوسط 64/5 سال بوده است. عوارض راه هوائی (شامل لارنگواسپاسم، برونکواسپاسم، ترشحات زیاد و نگهداری تنفس، ویزینگ و افت اشباع اکسیژن خون شریانی) دربین کودکانی که مواجهه غیر ارادی با دود سیگارداشته اند 3/54% و در سایر کودکان مورد مطالعه4/32? بوده که از نظر آماری معنی دار است(001/0P=). همچنین فراوانی عوارض حاد تنفسی در کودکان دختر در معرض دود سیگار 5/57% و در کودکان پسر در معرض دود سیگار 2/51% بود (012/0P=). عوارض حاد تنفسی در کودکان در معرض دود سیگار با مادر بیسواد در 7/76%، مادر با تحصیلات زیر دیپلم در 5/46% و در مادر با سواد تحصیلات بالای دیپلم در 5/12% مشاهده شد (002/P=). چنین ارتباطی بین عوارض تنفسی با سطح تحصیلات پدر هم در این مطالعه مشاهده شد (006/0P=). همچنین ارتباط معنی داری بین تعداد نخ سیگار با بروز عوارض تنفسی مشاهده شد (05/0P<).
    نتیجه نهایی: نتایج نشان دهنده وجود رابطه بین مواجهه غیرارادی با دود سیگار و عوارض تنفسی در کودکان تحت بیهوشی عمومی می باشد. این رابطه در دخترها بارزتر و در کودکانی که والدین آنها از سطح تحصیلات پائین تری برخوردار بوده اند شایعتر بوده است. بنابراین مواجهه غیرارادی با دود سیگار در کودکانی که تحت بیهوشی عمومی قرار می گیرند بایستی بعنوان یک ریسک فاکتور جهت پیش بینی احتمال بروز عوارض تنفسی حوالی عمل در نظر گرفته شود.

    Introduction &
    Objective
    Exposure to the environmental Tobacco smoke is associated with detrimental effects on pulmonary function in the children. This study investigated the relation between airway complications in children receiving general anesthesia with the passive inhalation of smoke and those who were not.
    Materials and Methods
    223 children scheduled to receive general anesthesia care were enrolled in this case-control study. The anesthesiologist and the residents, unaware of the smoke exposure history, recorded the occurrence of airway complications. A history of passive smoking was assessed by measuring the numbers of cigarettes smoked by their parents per day. The data was analyzed by c2statistical test.
    Results
    Respiratory complications occurred in 54.3% of the patients who were exposed to smoke and 32.4% of those who were not and the difference was statistically significant. Respiratory complications in daughters exposed to tobacco smoke was seen in 57.5% and in boys 51.2% (P=0.012). Respiratory events in children exposed to tobacco smoke was seen in 76.7% children with mother without education, 46.5% children of mothers with low educated level, and 12.5% children of mother with high educational level (P=0.002). This correlation was seen between respiratory events and educational level of fathers (P=0.006). Moreover, our study showed positive correlation between the number of cigarettes smoked per day with respiratory complications during general anesthesia (P<0.05).
    Conclusion
    There is a strong association between passive inhalation of tobacco smoke and respiratory complications in children receiving general anesthesia. The relationship was greatest for the daughters and those whose parents had a lower level of education. Passive smoking should be regarded as a risk factor for the children undergoing general anesthesia.

    Background

    Smoking has negative effects on reproductive process. Exposing tocigarette smoking (passive smoking) may exert some effects as the direct smoking.

    Objective

    The aim of this study was to evaluate the correlation between ovarianresponse and passive smoking in women who underwent ART cycles.

    Materials And Methods

    One hundred-sixty patients who underwent ICSI between2000 and 2001 were studied in a prospective cohort study. The case group includedwomen whose husbands smoked at least 5 cigarettes daily for 1 year or more. Thecontrol group included women with nonsmoking husbands. Women with high FSHlevel (>12 IU/ml) were excluded. Long standard protocol with GnRH agonist and HMGwere used in all patients. In vitro fertilization and embryo transfer was carried out in astandard fashion.

    Results

    Eighty one women were in case group and 82 in control group. Ovarianresponse variables were not significantly different between two groups but there was asignificant relation between passive smoking and fertilization (RR= 1.18, 95% CI: 1.07-1.31). However pregnancy rate was not significantly different between two groups.Moreover there were no significant differences between heavy and light smokers inovarian response outcomes.

    Conclusion

    This study showed no correlation between ovarian response parametersand passive smoking in women underwent ART cycles, whereas fertilization rate issignificantly lower in this group compared to control group. It may be related to spermquality than oocytes. Assessment of nicotin in follicular fluid and cytogenetic evaluationof embryo before transfer are recommended for more information and confirmation.

    در خصوص عوارض و اثرات جانبی استنشاق دود محیطی در میان کسانی که خود سیگاری نیستند، مطالعات اندکی صورت گرفته است. هدف از انجام این مطالعه تعیین ارتباط استنشاق دود محیطی بر سر انجام حاملگی بود.

    روش بررسی

    این مطالعه از نوع توصیفی- تحلیلی و بر روی 600 نفر زن غیر سیگاری که بچه یک قلو و زنده به دنیا آورده بودند در بخش زایمان مرکز آموزشی – درمانی هاجر شهرکرد مورد بررسی قرار گرفتند. جهت جمع آوری اطلاعات از پرسشنامه استفاده شده و سرانجام مادر و جنین در گروهی از مادران که در دوران بارداری در معرض دود سیگار قرار گرفته بودند با آنهایی که در معرض دود قرار نگرفته بودند، مورد مقایسه قرار گرفت. جهت تجزیه و تحلیل اطلاعات از نرم افزار SPSS، جهت مقایسه متغیرهای کمی از آزمون تی، جهت مقایسه متغیرهای کیفی از آزمون دقیق فیشر و جهت تعیین مهمترین عامل موثر در بین عواملی که ارتباط معنی داری با در معرض دود بودن مادر در حاملگی داشتند از آزمون رگرسیون لجستیک استفاده گردید.

    نتایج

    از 600 مادری که در این مطالعه مورد بررسی قرار گرفتند 236 نفر (3/39 درصد) در معرض دود سیگار قرار گرفته بودند. شیوع نوزادان نارس در مادران بیشتر در گروهی بود که در معرض دود قرار نگرفته بودند (2/15درصد در مقابل 9/7 درصد، 001/0=P)، تعداد نوزادانی که نسبت به سن حاملگی کوچکتر بودند، نیز در این گروه بیشتر بود(4/15درصد در مقابل 8/6 درصد، 0001/0=P). میانگین وزن نوزادان در این گروه 139 گرم کمتر از گروهی بود که در معرض قرار نگرفته بودند (402±49/3094 گرم در مقابل 443±99/3233 گرم، 001/0=P). شیوع آنمی نیز در این گروه از مادران بیشتر بود (005/0=P). آزمون رگرسیون چندگانه لجستیک نشان داد که در معرض دود بودن در دوران حاملگی به طور معنی داری با خطر بیشتر کوچک بودن برای سن حاملگی همراه است.

    نتیجه گیری

    در معرض دود بودن مادر در دوران حاملگی با خطر بیشتر کوچک بودن نوزاد نسبت به سن حاملگی همراه است.

    Introduction

    Adverse health effects of exposure to environmental tobacco smoke (ETS) among non-smokers have been studied occasionally in developing countries. The aim of this study was to determine the effects of exposure to ETS on outcome in pregnancy

    Methods

    In this descriptive and analytical study 600 non-smoking women delivering a singleton live baby were studied in delivery room in Hajar hospital in Shahrekord . A pre-designed structured questionnaire was used to record the details of exposure to ETS . Mother and infants outcomes were compared among those who were exposed to ETS vis-à-vis not exposed . We used spss software for analysis of data . Unpaired Student t-test was used for the comparison of continuous variables and Fisher’s Exact test was used for categorical variables. Multiple logistic regression analysis was performed after including all variables found to have significant differences on univariate analysis.

    Results

    Of the 600 women studied 236 (39.3%) were exposed to ETS. In these mothers there was a significantly higher incidence of pre-term birth (15.2% versus 7.9% , P = 0.001) and small-for-gestation babies (15.4% versus 6.8% , P= 0.0001) as compared to unexposed mothers. The mean birth weight of the babies born to the mothers exposed to ETS was 139 g less than that of babies in the unexposed group (3094.49 ±402 g versus 3233.99 ±443 g respectively, P= 0.001). The incidence of anemia was higher in exposed than unexposed mothers (P= 0.005) . The multiple logistic regression analyses showed that ETS exposure during pregnancy was significantly associated with a higher risk of small-for-gestation babies .

    Conclusion

    Exposure to ETS during pregnancy is associated with higher risk of having a small-for-gestation baby.

    زمینه و هدف
    سیگار کشیدن یکی از مشکلات جهان امروز است که سلامت انسان ها را به شدت تهدید می کند و زنان باردار که از گروه های آسیب پذیر جامعه هستند نیز از صدمات و عوارض آن مصون نیستند. به دنیا آوردن نوزاد کم وزن در بین زنان سیگاری امروزه امری ثابت شده است، اما در رابطه با تاثیر دود سیگار محیطی بر وزن و قد نوزادان مادرانی که در دوران بارداری در معرض دود سیگار بوده اند مطالعات نتایج آشکاری را ارایه ننموده است. مطالعه حاضر با هدف تعیین تاثیر دود سیگار محیطی بر وزن و قد نوزادان متولد شده طراحی و اجرا گردید.
    روش کار
    مطالعه از نوع هم گروهی گذشته نگر است. جهت انجام بررسی 100 زن باردار که در معرض دود سیگار محیطی قرارداشتند و 100 زن باردار که در معرض نبودند مورد مطالعه قرار گرفتند. ابتدا چک لیستی که حاوی مشخصات مربوط به شرایط ورود به مطالعه بود تکمیل شد و در صورت احراز شرایط نمونه ها از بین جامعه پژوهش وارد مطالعه می شدند. نمونه گیری به صورت غیر احتمالی مبتنی بر هدف انجام شد و پرسشنامه ای حاوی مشخصات فردی و خصوصیات فیزیکی نوزادان متولد شده در دو گروه تکمیل شد.
    یافته ها
    میانگین سن مادران، میزان تحصیلات مادران، میزان تحصیلات همسرانشان، تعداد حاملگی ها و جنس نوزادان متولد شده در دو گروه اختلاف معنی داری نداشتند و دو گروه از این جهات همگون بودند. در گروه در معرض دود سیگار محیطی مادران بطور متوسط در 24 ساعت 28/2 ± 36/2 ساعت در معرض دود سیگار محیطی قرارداشتند و اکثریت آنها (72 %) در معرض دود سیگار همسرانشان قرار گرفته بودند. نتایج مطالعه نشان داد که اختلاف وزن، قد و دور سر به ترتیب در دو گروه 11 گرم، 15/0 سانتی متر و 02/0 سانتی متر بود که با انجام آزمون آماری تی اختلاف معنی داری بین آنها وجود نداشت.
    نتیجه گیری
    نتایج این مطالعه نشان داد که وزن، قد و دور سر نوزادان بدنیا آمده از مادرانی که در دوران بارداری در معرض دود سیگار محیطی قرار داشتند کمتر از نوزادان مادرانی بود که در معرض دود سیگار محیطی قرار نگرفته بودند ولی این اختلاف از نظر آماری معنی دار نبود

    Background and Objectives
    Smoking is one of the major problems in the world today. It threatens people ’ s health. Pregnant women are no exception in this regard. Today, it is found that smoker women bear low birth weight babies, but the studies don ’ t offer clear findings about passive smoking in pregnancy and its effect on weight and height of newborns. This study is an attempt to determine the effects of passive smoking on the weight and height of the newborn babies.
    Methods
    This was a retrospective cohort study. We studied 100 pregnant mothers who were exposed to cigarette smoke and 100 others who were not. A checklist was completed in order to select those who could enter the study. A questionnaire was then filled out for both groups including the information related to the newborns ’ physical specifications.
    Results
    This study showed that the average age of the mothers, their education, their husband ’ s education, number of pregnancies and the sex of babies born weren ’ t meaningfully different between the two groups. In the case group the mothers were exposed to cigarette smoke for 2.36 ± 2.28 hours on average and most of them (72%) were exposed to their husbands ’ cigarette smoke. The findings also indicated that difference in weight, height and head circumference among two groups ’ newborns were 11 grams, 0.15 cm and 0.02 cm respectively. The T-test indicated no significant difference between the two groups.
    Conclusion
    The study showed that the newborns ’ of mothers exposed to the smoke had lower weigh, height and head circumference than the babies ’ of the control group subjects although the difference was not statistically significant.
