    Full Text Available To evaluate the effect of smoking habits on sleep, data from 1492 adults referred to the Sleep Institute were accessed and divided into 3 categories of smoking status: current, former and non-smokers. Categories of pack-years (<15 and ≥15 defined smoking severity. The association of smoking status and smoking severity with sleep was analyzed for sleep parameters, especially apnea and hypopnea index (AHI ≥5, more than 5% of total sleep time (TST spent with oxyhemoglobin saturation (SaO2 <90%, and arousal index. The arousal index was higher among current (21 ± 17 and former smokers (20 ± 17 than non-smokers (17 ± 15; P < 0.04. Former smokers had a higher percent of TST at SaO2 <90% than non-smokers (9 ± 18 vs 6 ± 13; P < 0.04. Former smokers with pack-years ≥15 compared to <15 exhibited higher AHI (22 ± 24 vs 16 ± 21; P < 0.05 and arousal index (22 ± 19 vs 18 ± 15; P < 0.05. Current smokers with pack-years ≥15 compared to <15 exhibited higher arousal index (23 ± 18 vs 18 ± 16; P < 0.05 and percent of TST at SaO2 <90% (11 ± 17 vs 6 ± 13; P < 0.05. Smoking status and pack-years were not associated with AHI ≥5 on logistic regression analysis, but current smokers with pack-years ≥15 were 1.9 times more likely to spend more than 5% of TST at SaO2 <90% than non-smokers (95%CI = 1.21-2.97; P = 0.005. The variability of arousal index was influenced by gender, AHI and current smokers with pack-years ≥15 (all P < 0.01. Smoking habits seem to be associated with arousal and oxyhemoglobin desaturation during sleep, but not with AHI. The effect was more pronounced in current than former smokers.

    Full Text Available Abstract Smoke-free environments in Greece are scarce. Despite existent legislation that forbids smoking in all health care service centers, smoking is still evident. Using a random sample of hospital personnel from a large university hospital in Greece, we evaluated their smoking habits, perceptions and compliance towards hospital smoking regulations. 57.8% of the nursing personnel and 34.5% of medical/research staff were found to be current smokers (p

    Smoking is still now the main avoidable cause of disease, disability and mortality in industrialized countries. This habit is still very common in workplaces, where anti-smoke efforts seem to be less incisive than among general populations. The study analyzed the diffusion of smoke habit in 8111 male workers in Campania region, employed in different work activities (white collars, blue collars, drivers, cleaning civil servants, porters), so as to evaluate work related features, affecting its assumption and maintenance. Among all workers, smokers prevalence (42.7%) was higher than national male population. Percentages of smokers were highest among drivers (60.7%) and civil servants (52.5%), slightly lower among industry workers (47.3%) and lower among white collars (36.4%). The highest prevalence were found in 41-50 years age group (46.8%), but only among white collars aging was associated with higher smokers prevalence. Lower education degrees and two working variables, shifts and handwork, have been related with significantly smoking habit assumption. Results emphasized that health promotional programs are necessary to reduce smoke habit among workers, particularly among professionally and culturally unqualified subgroups.

    Abstract Previous studies have warned against the promoting effects of cigarette smoking on benign prostatic hyperplasia (BPH). In contrast, some have argued that smoking confers a protective effect regarding BPH, while others have observed an aggravated effect. Thus, we performed this meta-analysis to determine whether cigarette use is associated with BPH risk. To identify articles from observational studies of relevance, a search was performed concurrent to March 21, 2016, on PubMed, Web of Science, Cochrane, EBSCO, and EMBASE databases. Random-effect model, according to the heterogeneity, was calculated to reveal the relative risks (RRs) and corresponding 95% confidence intervals (CIs). Eight articles were included in this meta-analysis, representing data for 44,100 subjects, of which 5221 (11.8%) had BPH as defined according to the criteria. Seven reports are concerned with analysis between nonsmokers and ex-smokers, in which no significant difference was observed (RR = 0.99, 95% CI 0.94–1.05). Another meta-analysis of 7 studies indicated an observable trend, but without significant difference between groups of nonsmokers and current smokers (RR = 1.17, 95% CI 0.98–1.41). Between groups of heavy (6 articles; RR = 1.02, 95% CI 0.84–1.24) and light smokers (5 articles; RR = 0.90, 95% CI 0.71–1.15), again no significant difference appears. Finally, we combined individuals as never-smokers and ever-smokers and still found no significant difference between the 2 groups of patients (RR = 1.03, 95% CI 0.92–1.15). Sensitivity analysis was displayed and confirmed the stability of the present results. Combined evidence from observational studies shows no significant association between cigarette smoking and BPH risk, either for ex-smokers or for current smokers. The trend of elevated BPH risk from smoking was observed only in current smokers compared with nonsmokers, while marginal significance was observed in comparing ever-smokers with

    A cross-sectional study was conducted to identify the factors related to smoking habits of adolescents among secondary school boys in Kelantan state, Malaysia. A total of 451 upper secondary male students from day, boarding and vocational schools were investigated using a structured questionnaire. Cluster sampling was applied to achieve the required sample size. The significant findings included: 1) the highest prevalence of smoking was found among schoolboys from the vocational school; 2) mean duration of smoking was 2.5 years; 3) there were significant associations between smoking status and parents' smoking history, academic performance, perception of the health hazards of smoking, and type of school attended. Peer influence was the major reason students gave for taking up the habit. Religion was most often indicated by non-smokers as their reason for not smoking. Approximately 3/5 of the smokers had considered quitting and 45% of them had tried at least once to stop smoking. Mass media was indicated as the best information source for the students to acquire knowledge about negative aspects of the smoking habit. The authors believe an epidemic of tobacco use is imminent if drastic action is not taken, and recommend that anti-smoking campaigns with an emphasis on the religious aspect should start as early as in primary school. Intervention programs to encourage behavior modification of adolescents are also recommended.

    Background: University students worldwide seem to have increased rates of smoking, alcohol abuse, binge drinking episodes and harmful consumption trends, raising a serious public health issue. The aim of the present study was to investigate university students’ smoking habits and exposure to secondary smoke amid a financial crisis. Methods: The present descriptive, correlational analysis was conducted at the University of Peloponnese. Results: The average age of the sample (n=203) was 24.9 years (±7.6 years) with 36.0% of the participants (n=73) being postgraduate students. Some 51.2% (n=104) of the participants said they didn’t smoke and 46.3% (n=94, p=0.003) reported no secondary smoke exposure during the past week at home. The majority of the remainder initiated smoking at age 16-17 (48.5%, n=48), and 64.6% (n=42) said the financial crisis did not lead them to change their smoking habits. Conclusions: The majority of students support smoking ban laws in enclosed public spaces, but also their replies highlighted poor implementation on behalf of the state and the authorities. The financial crisis did not appear to have affected student smoking habits. Creative Commons Attribution License

    A survey of postpartum women in Brisbane revealed that many gave up smoking just before or shortly after becoming pregnant, and that many of the remainder reduced their rate of consumption. Husbands who smoked showed no comparable changes in behaviour. Thus apparently many couples were aware of the dangers to the fetus of active smoking by the woman, but not of the dangers of her passive inhalation of smoke. Other significant findings included (i) increasing rates of consumption during successive pregnancies, (ii) high degrees of conformity for most habits (e.g. use of filters), and (iii) stronger addiction and earlier starting ages among heavy smokers than light smokers.

    The inter-relationships between smoking habits and weight gain are complex. However, few studies have examined the association of smoking habits with weight gain over the life course. Major smoking parameters and weight gain over time were examined in a large cohort of postmenopausal women aged 50-79 years at enrollment between 1993 and 1998 (N=161,808) and followed through 2014 (analyses conducted in 2016). Cross-sectional analyses were used to assess the association of smoking and body weight at baseline. Retrospective data were used to correlate smoking status with body weight over a 45-year period prior to enrollment. In addition, the association of smoking with weight gain over 6 years of follow-up was examined. At baseline, women who had quit smoking prior to enrollment weighed 4.7 kg more than current smokers and 2.6 kg more than never smokers. Former, never, and current smokers all gained weight over the 45-year period from age 18 years to time of enrollment (average age, 63 years): 16.8, 16.4, and 14.6 kg, respectively. In prospective analyses, women who were current smokers at baseline but who quit smoking during follow-up gained more than 5 kg by Year 6 compared with current smokers at baseline who continued to smoke. Among long-term quitters, greater intensity of smoking and more recent quitting were associated with greater weight gain. These results suggest that excess weight gain associated with smoking cessation occurs soon after quitting and is modest relative to weight gain in never smokers over the adult lifespan.

    The present research was carried out at the School of Dentistry, Muhimbili University of Health and Allied Sciences, Tanzania. To assess smoking and drinking habits as well as attitudes towards smoking cessation counselling among dental students in Tanzania. A 28-item pretested and self-administered questionnaire was delivered to all dental students enrolled at the end of the 2006 academic year. The questionnaire covered socio-demographics, smoking and drinking habits, knowledge concerning health effects and attitudes towards smoking cessation counselling. Dental students enrolled at the end of the 2005/2006 academic year in the School of Dentistry, University of Dar-es-Salaam, Tanzania. Self-reported smoking, alcohol use and attitudes to smoking cessation counselling. The response rate was 73.2% (109/149) and 76.1% of respondents were male. Smoking was reported by 12.8%, all being male. Alcohol use during the last 30 days was reported by 23.8% and binge drinking during the last two weeks by 11.8%. Both smoking and alcohol use were more common among clinical than basic science students. The majority (67.0%) reported that they had not received education on smoking cessation counselling although 86.2% considered that dentists and physicians should provide such counselling. Reported smoking and alcohol consumption are on a low level compared to dental students internationally. Willingness and need for cessation counselling training was expressed by the majority of Tanzanian dental students. This should be taken into consideration in dental curriculum development.

    To study the impact of mild to moderate asthma on smoking habits in adolescents. Specifically, we tested the hypothesis that asthma does not prevent adolescents from smoking. A research questionnaire, filled by a systematic sample of military personnel upon enrollment to service in the Israeli Defense Force (IDF), was analyzed. Conscripts were asked to voluntarily fill (after obtaining a signed informed consent) a research questionnaire about their medical history, and several health related topics including smoking. This database was matched with the military medical profile of the soldier, which includes the patient asthma status. Overall, 38,047 young adults were included in this study. There was a significant increase in the rate of mild to moderate asthma, from the mid-1980's to date. During the 1980's and early 1990's, asthmatics smoked significantly less frequently (20-22%) than non-asthmatics (25-27%). In the mid- to late-1990's, the smoking rates increased relatively more in asthmatics, to the point that in the last 8 years of this study, they were found to be almost identical in both groups, at a rate of approximately 30%. The presence of asthma is not a powerful motivating agent to prevent from smoking. It is likely that smoking asthmatic teenagers are at risk for suboptimal lung growth, and as young adults, they will become at greater risk of lung function deterioration. We suggest that primary care physicians, caring for asthma in children, adolescents, and young adults, should explain the particular risks generated by tobacco smoking.

    The purpose of this study was to compare physical activity and eating habits of adolescent smokers with those of adolescent non-smokers in South Korea. This was a secondary analysis of data collected from the 2012 Korean Youth Risk Behavior Web-Based Survey. The sample included 72,229 adolescents aged 12 to 18. A multiple logistic regression analysis was performed to examine the association between smoking status and physical activity and between smoking status and eating habits, while controlling for other factors. Boys and girls were analyzed separately for all analyses. The proportion of self-reporting smokers was 11%. Surprisingly, girl smokers exercised significantly more frequently than non-smokers. Adolescent smokers were significantly less likely to consume fruits, vegetables, and milk/dairy products, and they ate significantly more fast-food than non-smokers. Health care professionals who plan smoking cessation programs should pay attention to South Korean adolescents' specific characteristics and cultural values in terms of health behavior.

    The aim of the study was to explore the prevalence of different smoking habits in a population of Austrian pupils, 12 to 15 years old, and the relationship of familial and peer group smoking customs with these habits. In 1997 a population-based survey (International Study of Asthma and Allergies in Childhood, ISAAC) was conducted of all 7th and 8th grade school children of a district of Upper Austria. Information on the smoking habits of the adolescents, the family members, and of the peer as well as smoking habits of the teacher, gender, and age of the children was collected. The overall-prevalence of having ever smoked in this population is 57.8%. The percentage of eversmokers among the 12-year-olds is 50%. This amount increases to 63.8% among the 14- to 15-year-olds. The odds ratios for smoking daily is highest among those whose best friend smokes (OR: 70.63, CI: 9.19, 542.40). The risk of daily smoking increases also if the siblings of the juvenile (OR: 4.71, CI: 1.15, 19.35) or the mother (OR: 4.95, CI: 1.67, 14.70) smoke. If the father smokes the risk to smoke monthly is increased (OR: 2.09, CI: 1.28, 3.40). These results point to the fact that smoking prevention programes should take into account the influence of peers and family of the adolescents.

    Full Text Available Background: This study aimed to assess the burden of household smoking habits on the occurrence of respiratory symptoms among young adolescents in Malaysia.Methodology: The impact of Secondhand Smoke (SHS exposures on the occurrence of respiratory symptoms was investigated on 234 adolescents (13-14 years old residing in two states in Malaysia. Adolescents completed a self-administered questionnaire adapted from Global Youth Tobacco survey that comprised of items on socio-demographic and SHS exposures. Respiratory symptoms were assessed using a standard questionnaire of International Study of Asthma and Allergies in Childhood. Hair samples were collected from each adolescent and were analyzed for nicotine via Gas Chromatography-Mass Spectrophotometry with nitrogen detection method.Result: The geometric mean of hair nicotine was 0.0184± 2.31 ng/mg. The prevalence of current, ever wheeze, nocturnal cough, exercised-induced wheeze and self-reported asthma were 7.69%, 14.1%, 11.5%, 20.5% and 13.7%, respectively. A significant association was found between household smoking status with exercise-induced wheeze (Adjusted Odds Ratio, AOR 1.06; 95%Confidence Interval, CI 0.42-2.66 and nocturnal cough (AOR 14.2; 95%CI 1.60-125. Reported ever wheeze was linked to reported SHS exposure in family’s vehicle (AOR 3.27; 95%CI 1.15-9.34. The risk of exercise-induced wheeze was related with postnatal SHS exposure (AOR 2.69; 95%CI 1.13-6.43.Conclusion: Respiratory symptoms were mostly affected by household smoking habits. Thus, in an attempt to reduce the repercussion of SHS exposure among younger adolescents, effort should be emphasized in encouraging parents to move from indoor to outdoor smoking far from the vicinity of children.Keywords: Passive smoking, Household smoking habits, Youth, Respiratory health, Hair nicotine

    1995-06-30

    In this article we present results from a qualitative study among 33 pregnant smokers, who took part in an in-depth interview in the 27th-35th weeks of pregnancy. The aim was to obtain insight into pregnant women's own experience of smoking in pregnancy. The pregnant women interviewed were concerned about their smoking habits. In spite of this, they still expressed positive attitudes towards smoking, and many did not experience pregnancy as a favourable time to stop. The study shows that pregnant women still lack important knowledge about the dangers of smoking. Pregnant smokers' attitudes towards scientific facts, and the role cigarettes play in their everyday lives, are considered to be important variables in determining smoking in pregnancy. The pregnant women experienced that their partner and health-personnel played a minor role in changing smoking behaviour. The reasons the women gave for smoking in pregnancy are discussed in the light of current theories on changing health behaviour. Four key questions are proposed which can be used by doctor and midwife to obtain knowledge of pregnant women's perception of the seriousness of smoking and the associated risks, and of the gains and barriers connected with quitting.

    Full Text Available Background/Aim. According to the number of active smokers, Serbia occupies a high position in Europe, as well as worldwide. More than 47% of adults are smokers according to WHO data, and 33.6% according to the National Health Survey Serbia in 2006. Smoking physicians are setting a bad example to patients, they are uncritical to this habit, rarely ask patients whether they smoke and rarely advise them not to smoke. These facts contribute to the battle for reducing the number of medical workers who smoke, as well as the number of smokers among general population. The aim of the study was to determine the smoking behavior, knowledge and attitudes and cessation advice given to patients by healthcare professionals in Serbia. Methods. A stratified random cluster sample of 1,383 participants included all types of health institutions in Serbia excluding Kosovo. The self administrated questionnaire was used to collect data about smoking habits, knowledge, attitudes and cessation advice to patients given by health professionals in Serbia. Results. Out of 1,383 participants, 45.60% were smokers, of whom 34.13% were physicians and 51.87% nurses. There were 46.4% male and 45.4% female smokers. The differences in agreement with the statements related to the responsibilities of health care professionals and smoking policy are significant between the “ever” and “never” smokers, and also between physicians and nurses. Twenty-five percent of nurses and 22% of doctors claimed they had received formal training. However, only 35.7% of the healthcare professionals felt very prepared to counsel patients, while 52.7% felt somewhat prepared and 11.6% were not prepared at all. Conclusions. According to the result of this survey, there are needs for more aggressive nationwide non-smoking campaigns for physicians and medical students. Experiences from countries where physicians smoke less and more effectively carry out smoking cessation practices need to be shared

    Tobacco during pregnancy affects the health of the newborn. The aim was to assess the effect of maternal exposure to active and passive tobacco and of smoking cessation on the risk of preterm deliveries and birth weight, taking into account other risk factors. Longitudinal study conducted in 282 healthy pregnant women. General, obstetrical and hematological data were collected as it was the smoking habit during pregnancy. Pregnant women were classified as "exposed to smoke" (active smoker and passive smoker) and "unexposed to smoke" (non-smokers and women who quitted smoking during pregnancy). A percentage of 59.2 were non-smokers, 18.4% active smokers, 8.5% second-hand smokers and 13.8% had stopped smoking. Unexposed pregnant women who stopped smoking had the same risk of premature deliveries and children with similar birth weight as non-smoker women. Active and second-hand smokers were at higher risk of preterm deliveries than non-smokers (odds ratio [OR] 6.5, 95% confidence interval [95% CI] 1.4-30.8 and OR 6.2, 95% CI 1.0-38.9, respectively); however, higher levels of hemoglobin in the 1st and 3rd trimester exerted a protective effect (OR 0.9, 95% CI 0.8-0.9). Active and second-hand smokers had babies weighing less than non-smokers (around 129 and 178g less, respectively). Active or passive exposure to smoke during pregnancy and lower hemoglobin levels are associated with an increased risk of premature deliveries and lower birth weight. Stopping smoking during pregnancy prevents these detrimental effects. Copyright © 2013 Elsevier España, S.L. All rights reserved.

  7. Sigmund Freud: smoking habit, oral cancer and euthanasia.

    2004-01-01

    Sigmund Freud, the father of modern psychoanalysis had a well-known love of the cigar. The natural progression of this vice was the development of oral cancer for which he underwent a lengthy ordeal. An account is given in this article of Sigmund Freud's illness and care following the diagnosis of his oral cancer. The role of euthanasia and physician assisted suicide is also discussed. A review of relevant literature on Sigmund Freud's illness, risk factors for oral cancer and euthanasia was undertaken. Sigmund Freud was a heavy smoker with a 20-cigar/day habit. In 1923, a diagnosis of squamous cell carcinoma of the palate was made, for which he underwent a lengthy ordeal which span a total of 16 years. During this period, he bluntly refused to quit smoking. Freud consulted many specialists (otolaryngologists, oral and maxillofacial surgeons, prosthodontists and general surgeons), during the course of his ordeal with oral cancer. He underwent 34 surgical procedures before his eventual death in 1939 through euthanasia. Continued indulgence in smoking and procrastination on the part of Freud, as well as mediocrity, negligence and incompetence on the part of the first surgeon that operated on Freud, could partly be responsible for his lengthy ordeal.

    Full Text Available The aim of our study was to investigate the prevalence of smoking in a Greek working population. A questionnaire regarding smoking habit was collected from 1,005 out of 1,200 blue and white-collar employees (response rate: 84%. The overall smoking prevalence was 48.4% and did not differ by sex, age, education, and occupation. The mean cigarette consumption per day was 25.54, with no difference observed by occupation. The above-mentioned findings, if confirmed by further research, are alarming and inconsistent with the prevalent pattern of smoking habits in the West.

    Schizophrenia and bipolar disorder show high comorbidity with smoking dependence. Several previous studies reported that glycogen synthase kinase 3β (GSK3β), which is widely expressed in the brain including the dopamine projection areas such as the amygdala, nucleus accumbens and hippocampus, may play a role in neuropsychiatric disorders and dopamine- and serotonin-mediated behavior. In this study, we have analyzed the association of three single nucleotide polymorphisms (SNPs) within GSK3β gene (rs3755557, rs334558, rs6438552) with the smoking habits and age at smoking initiation in a sample of 384 young adult Japanese, which included 172 smokers and 212 non-smokers. As a result, rs334558 was significantly associated with smoking habits in genotype frequency and allelic frequency (P smoking habits.

    2013-09-01

    Full Text Available This article examines the influence of intimate relationships on smoking habits and body weight. We differentiated between couples living apart together, cohabitating couples and married couples. The data basis is the Partnermarktsurvey, a German representative telephone survey of 2,002 people aged between 16 and 55 years. The results show that living in a relationship promotes smoking cessation, however only when the partners live together. This indicates that the positive protection effect of relationships on smoking habits is based on the mechanism of social control and social support, which is linked to the context of a shared household. In addition, we observed the homogamy in smoking habits of partners that arises as early as mate selection and is intensified through assimilation processes during the relationship. With regard to body weight, the study shows a weight gain over the course of a relationship which is, however, not greater among married and cohabitating couples than among couples living apart together.

  19. Family meal traditions. Comparing reported childhood food habits to current food habits among university students.

    De Backer, Charlotte J S

    2013-10-01

    The aim of this study is to investigate if reported childhood food habits predict the food habits of students at present. Questions addressed are: does the memory of childhood family meals promote commensality among students? Does the memory of (grand)parents' cooking influence students' cooking? And, is there still a gender difference in passing on everyday cooking skills? Using a cross-sectional survey, 104 students were asked about their current eating and cooking habits, and their eating habits and the cooking behavior of their (grand)parents during their childhood. Results show that frequencies in reported childhood family meals predict frequencies of students' commensality at present. The effects appear for breakfast and dinner, and stay within the same meal: recalled childhood family breakfasts predict current breakfast commensality, recalled childhood family dinners predict current dinner commensality. In terms of recalled cookery of (grand)parents and the use of family recipes a matrilineal dominance can be observed. Mothers are most influential, and maternal grandmothers outscore paternal grandmothers. Yet, fathers' childhood cooking did not pass unnoticed either. They seem to influence male students' cookery. Overall, in a life-stage of transgression students appear to maintain recalled childhood food rituals. Suggestions are discussed to further validate these results.

    To explore whether parental behaviours related to smoking socialisation and parenting are associated with smoking susceptibility and current smoking in 14-15 year old students. Data were sourced from the New Zealand 2006 Year 10 In-depth Survey, a school-based survey of 3,189 students. Outcome measures were susceptibility to smoking and current smoking. Potential determinants were second-hand smoke exposure in the home, parental smoking, parental anti-smoking expectations, anti-smoking rules, pocket money, monitoring of pocket money expenditure, general rule setting and monitoring, and concern about education. Analysis used logistic regression to adjust for potential confounding factors. Exposure to second-hand smoke and lack of parental anti-smoking expectations were independently associated with smoking susceptibility and current smoking. Parental smoking was not independently associated with current smoking or susceptibility. Receiving pocket money and an absence of monitoring of expenditure were associated with smoking susceptibility and current smoking. Lack of parental rule setting was associated with smoking susceptibility. Findings were similar whether or not one or more parents were smokers. Not allowing smoking in the home, communicating non-smoking expectations to children, monitoring pocket money, and setting rules to guide behaviour are strategies which are likely to reduce risk of smoking uptake. The study provides evidence to inform the development of parent-focused interventions to reduce the risk of smoking initiation by children. © 2011 The Authors.

    This paper evaluates the causal relationship between smoking and body weight through two waves (2004-2006) of the British Household Panel Survey. We model the effect of changes in smoking habits, such as quitting or reducing, and account for the heterogeneous responses of individuals located at different points of the body mass distribution by quantile regression. We test our results by means of a large set of control groups and investigate their robustness by using the changes-in-changes estimator and accounting for different thresholds to define smoking reductions. Our results reveal the positive effect of quitting smoking on weight changes, which is also found to increase in the highest quantiles, whereas the decision to reduce smoking does not affect body weight.

    Smoking is still one of the most dangerous and avoidable health risks. This study "Healthy air at work" analysed smoking habits, state of change, the influence of the diagnosis F.17.0 in patient treatment and estimation of subjective workloads and personal resources in health-care workers. Almost 2 000 questionnaires were analysed. 19.9% of this study population were smokers, while 26.4% were considered to be heavy or very heavy smokers. Half of the current smokers were willing to change, while the majority had already tried to quit multiple times. The most important motive to stop smoking was fear of consequences (44.4%), followed by other reasons (42.3%) (e. g., pregnancy) and expenses (33.9%). Protection against second-hand smoke was estimated mostly as very relevant, especially for patients. Being a role model in terms of tobacco consumption seems to be important for health-care workers. 61.3% of all health-care workers stated that patients' nicotine dependency had been diagnosed and out of these 46.5% say it is a relevant factor in therapy. 60% of all interviewed employees evaluated themselves as working quantitatively under heavy and very heavy workloads, while 20% had to deal with high qualitative challenges. In terms of future work ability and personal resources 75% were considerably optimistic. We did not find any relation in terms of workloads and smoking habits. Rather few health-care workers used nicotine replacement therapy during former cessation trials. Health-care workers could play an important role in the treatment and prevention of smoking dependency. This potential is not used to its full extent up to now.

The environment of the study is Elazig and the samples of the study are the fitness and sport centers. To get the data a questionnaire form made up of four parts was used. In the 1 st part questions about personal information and family, in the 2 nd part questions about personal information of the person who attended the study, in the 3 rd part questions about daily smoking habits, in the 4 th part questions about smoking behaviors were asked. For the study 200 questionnaires were used, frequency and percentage distribution was calculated and given. Freque ncy and percentage distribution of daily smoking habits and personal information of people doing fitness and sports who attended the study were shown. Smoking habits of people who does fitness and sports were tested by using the questionnaire. 200 peopl e answered the questionnaire. %15 of the attendees were aged 17 - 18, %10 aged 19 - 20, %15 aged 21 - 22, %25 aged 23 - 24, %35 aged over 25. %85 of the attendees were single and %15 of them were married. %10 of the attendees were living in big cities, %80 of them were living in city centers, %5 of them were living in counties and %5 of them were living in towns or villages. %85 of the attendees had elementary families, %12 of them had extended families and %13 of them had separated families. As a result accordin g to the study the rate of smoking habit among the people who are doing fitness and sport is high also it is seen that the smoking rate of man is higher than the smoking rate of women. The students attended to the questionnaire who wanted to be a model for not smoking get 0.85 points in other words %85 give. Also panels and conferences should be given to people who does fitness and sport to tell them the negative effects of smoking to the performance and health of the sportsman to make them stop smoking.

    To examine the association between an IL6 (Interleukin-6) polymorphism (C-634G or rs1800796) and tooth loss, and an interaction between the polymorphism and smoking habits for the loss. Our subjects were 4917 check-up examinees ages 35-69. They reported tooth loss and lifestyle in a questionnaire. We regressed the number of teeth on the IL6 genotype, gender, age, smoking, drinking, diabetes, hypertension, physical activity, energy intake, education, and brushing. We further estimated multivariate-adjusted odds ratios (ORs) for having smoking and tooth loss was stronger among those with GG than among those with CC. In a multiple regression analysis, a significant interaction was found between GG genotype and current smoking in the prediction of tooth loss (P = 0.018). The IL6 C-634G polymorphism was significantly associated with tooth loss. Our results suggest greater effects of smoking on tooth loss in GG genotype individuals. © 2015 John Wiley & Sons A/S.

    Full Text Available Objective: We aimed to evaluate the role of drinking alcohol, coffee and tea habits, fear of gaining weight and treatment methods in smoking cessation success. Methods: In our study, we applied a questionnaire and Fagerström Test for Nicotine Dependence to 128 participants consulting Family Medicine Smoking Cessation Outpatient Clinic of Ankara Training and Research Hospital. Among participants, 67 of them were people quitted smoking while the other 61 did not. With questionnaire, we investigated factors possibly affecting smoking cessation success like drinking alcohol, coffee and tea habits and also marital status and occupations of participants. By adding Fagerström Test for Nicotine Dependence to questionnaire we defined the dependence status of participants. Results: Study comprised of 128 participants, 50 of them being female and 78 being male. Mean age of participants was 34.01 (±12.24 in patients quitted smoking and 32.82 (±13.45 in patients still smoking. Tea and alcohol drinking habits were found to be higher in smoking group and difference was statistically significant (p<0,05. When examining smoking cessation success according to occupational groups, civil servants and unemployed people were more successful than other occupational groups, but there was no statistically significant difference. People having coffee drinking habits quitted smoking in a significantly higher rate (p<0,05. Among given treatments, although statistically insignificant, the most effective one was varenicline. Conclusion: According to our results, smoking cessation success is lower among people having tea and alcohol drinking habits. In smokers, we should investigate the relationship with additional substance usage and aim to decrease these additional substance usage habits for increasing smoking cessation success.

    Modern European health education programmes place particular emphasis on the issue of tobacco-related diseases. It is a direct result of research studies showing that nicotine dependence and its consequences are a very important problem of modern European societies. In Poland the epidemic of chronic noncontagious diseases related to the inhalation of cigarette smoke remains a major health problem and a threat to public health condition. It is confirmed by a high number of premature deaths and complications following the course of malicious tumors, cardiovascular diseases, nonneoplastic respiratory diseases and by the deaths of infants born to mothers smoking during pregnancy. In 2006, first survey concerning smoking among university students was held at the Institute of Cosmetology and Health Care in Bialystok. Given all these arguments and the fact that the School is a medical university, in the 2006/2007 academic year a preventive health programme called "Healthy Bialystok 2006-2009" was introduced. It is addressed to both regular and extramural students of the following courses: Cosmetology, Emergency Medical, Nursing and Physiotherapy at the Institute of Cosmetology and Health Care in Bialystok. The main objective is to encourage students either not to smoke or give up smoking, and if this is impossible- to minimize the effects of smoking and to promote a healthy lifestyle. In the 2009/2010 academic year, the survey covered all first year students majoring in Cosmetology at the Institute of Cosmetology and Health Care in Bialystok. Test-takers were guaranteed anonymity. The questionnaire consisted of questions about the origins and reasons of smoking, number of cigarettes smoked per day, environment of the surveyed, knowledge of tobacco-related diseases and attempts to give up the habit.

    This school-based study aimed to investigate the prevalence of being at risk for depression, bullying behavior, and current smoking among Chinese adolescents in order to explore gender differences in the vulnerability of adolescents with these behaviors to develop a smoking habit. A total of 35,893 high school students sampled from high schools in eighteen cities in China participated in the study from 2011 to 2012. Overall, the prevalence of current smoking was estimated at 6.4%. In total, 1.7% (618) of the participants admitted to bullying others, 5.8% (2071) reported being bullied, 3.5% (1269) were involved in both bullying others and being bullied, and 5.6% (2017) were at high risk for depression. Logistic regression analysis indicated that among girls, with high depression risk, bullying others, being bullied, and both bullying others and being bullied were independently and positively associated with current smoking habits, while the final results among boys showed that bullying others and both bullying others and being bullied were independently associated with an increased risk of current smoking. School-based prevention programs are highly recommended, and we should focus on high-risk students, particularly girls with high risk of depression or involved in school bullying and boys who are involved in school bullying.

    The relationship between cigarette smoking, vodka drinking and consumption of 44 food items typical of the Polish diet were analysed in a case-control study in Cracow, Poland, among 127 cases of breast cancer and 250 controls randomly selected from the general population. Cigarette smoking was not significantly influencing the breast cancer risk. Compared with never-drinkers, the habit of vodka drinking 20 years earlier significantly increased breast cancer risk in women below 50 years of age (multivariate OR was 4.4 with 95% CI 1.6-12.4). Frequent consumption of boiled vegetables 20 years earlier (greater than 3 times per week) was associated with a decreased risk of breast cancer in women aged 50 years and more (multivariate OR was 0.4 with 95% CI 0.2-0.8).

    Aim: The aim of this study was to find out at what age children start smoking, as well as their tobacco habits and risk perceptions according to the different school-age groups.

    Methods: A cross-sectional survey was carried out in 2007; it involved around 1700 students of the Catania province, in Southern Italy. The students filled in a structured tobacco questionnaire. They did it anonymously in the classrooms. Main outcome measures were initiation of smoking, smoking habits, number of cigarettes smoked per day and risk perception.

    Results: From the first year of the primary school to the last year of the high school the proportion of daily smokers increased from 0.0% to 11.8% for girls and from 0.8% to 12.7% for boys. For both genders the initiation of smoking habits occurred mainly at age 10 to 13. Finally, girls had a better risk perception.

    Conclusions: Studying young people’s tobacco habits over time gives an understanding of when preventive measures have to be implemented. In order to influence smoking attitudes, these preventive interventions must be put in place before children start experimenting tobacco.

    As part of our ongoing mortality surveillance program for the US man-made vitreous fiber industry, we surveyed a random sample of study members to estimate tobacco-smoking habits for the total cohort. Separate sampling frames were constructed for four study groups: male and female workers within the fiberglass and rock/slag wool subcohorts. The frames included all persons who had worked a year or more between 1945 and 1986 (with some exceptions), and who were alive as adults (18+ years) on January 1, 1980, the year the age distribution of the cohort most resembled the US comparison population. Subjects were randomly selected from the frames, and a structured telephone interview was administered to the subject or a proxy respondent between January 1995 and December 1997. Using survey data, we estimated the point prevalence of ever and current cigarette smoking on January 1, 1980, and made comparisons with other occupational groups and general populations. Overall response rates (interviews/targeted sample) were greater than 78% for each of the four study groups. From our estimates, we infer that male workers from both the fiberglass and rock/slag wool cohorts and female rock/slag wool workers had higher rates of ever smoking than the corresponding general populations of the United States and most of the states where the study plants were located. These findings suggest that at least part of the elevated externally standardized mortality ratios (US and regional rate-based) for respiratory system cancer noted among male subjects and the male-dominated total cohort in our previous cohort analyses were due to uncontrolled positive confounding by smoking.

    Full Text Available Phenylthiocarbamide (PTC is known as phenylthiourea and it is an organic compound that has the phenyl ring. Ability to perceive the tastes of PTC chemical is related to the dominance of taste genes. There are a large number of population studies regarding the PTC taste perception and different personal characteristics or disease conditions. The purpose of this study is to reveal and compare the relation between the PTC taste perception and work-out habits, smoking, alcohol consumption and tendency to the depression of people. A total of 2500 adults were volunteered to be included in this study. PTC taste perception was measured by tasting with PTC solution (10 mg/L filtered in a paper. It showed that tasters were significantly more frequent (81.8% than nontasters (18.2% in all population. And in some parameters analyzed in this study, there are significant differences. The taste genetics show up with environmental factors and create the sense of taste, which develops the feeding behaviors. The taste perception resulting from food and beverages diversifies by genetic and environmental effects and the nervous system interprets this perception. This study is enlightening in terms of presenting that the taste perception of people affects their lifestyles and lead them to start and either continue or discontinue some habits.

    Full Text Available Objectives The present study was undertaken to assess the prevalence of smoking and chewing habits and causes of addiction among the school children of rural areas.Methods This cross-sectional study was conducted in four secondary schools from rural areas of Bankura District, West Bengal during August 2012 to September 2012. Total 1674 students studying in 5th to 10th standard (age group of 10-15 years were enrolled in the present study. A self-administered questionnaire was applied for data collection.Results The study showed that 18.45%, 27.95% and 67.56% of the students were smokers, chewer and non-addicted, respectively. Considerable number of boys were addicted with smoking (boys 32.3% vs. 4.33girls % and chewing habits (boys 43.53% vs 12.15girls %. In case of boys, these habits were increased with advancement of ages. Students were more attracted to bidi and tobacco with pan-masala among different types of smoking and chewing agents. The most familiar reasons for tobacco user were: influenced by friends (22.88%, influenced by family members (16.32% and stress relief (10.88%. Conclusion This study indicated that smoking and chewing habits among school children in rural areas is looming public health issue. Adverse health effect of tobacco use may be incorporated in school secondary curriculum to change the attraction with tobacco among the young generation.

    Plate tectonics is one of the major factors affecting the potential habitability of a terrestrial planet. The physics of plate tectonics is, however, still far from being complete, leading to considerable uncertainty when discussing planetary habitability. Here, I summarize recent developments on the evolution of plate tectonics on Earth, which suggest a radically new view on Earth dynamics: convection in the mantle has been speeding up despite its secular cooling, and the operation of plate tectonics has been facilitated throughout Earth's history by the gradual subduction of water into an initially dry mantle. The role of plate tectonics in planetary habitability through its influence on atmospheric evolution is still difficult to quantify, and, to this end, it will be vital to better understand a coupled core-mantle-atmosphere system in the context of solar system evolution. © 2012 New York Academy of Sciences.

    The aim of the study was to analyse the effects of smoking, in particular to show its causal role in the development of airflow obstruction, and to look at changes in smoking habits. The study was conducted among 556 men, aged 30 to 54 in 1960, surveyed twice, in 1960 and 1972. The hypothesis of tobacco as a causal factor of airflow obstruction is strengthened, following this study, by three results: 1) FEV1 slope was related to tobacco consumption, even after adjustement for FEV1 level (42 ml/yrs for non-smokers, 51 ml/yrs for heavy smokers); 2) FEV1 loss with age increased with the amount of tobacco consumption: one pack a day smoked for 25 years was equivalent to an aging of 5 years; 3) FEV1 loss decelerated if the subject gave up smoking, thus preventing any further risk. What appeared to be a spontaneous regulation in smoking habits was observed. The men who stopped smoking were those with low respiratory status. In this population, men who were ex-smokers in 1960 and maintained this status until 1972 had a FEV1 slope similar to that of the non-smokers.

    This study aimed to assess the prevalence of cigarette smoking among medical students, and to determine their level of knowledge regarding risk associated with cigarette smoking and their attitude and behavior towards tobacco control strategies and policies. A stratified random sampling approach was used to select participants. A modified version of the the Global Health Professional Students Survey questionnaire was self-administered. Descriptive statistics were applied and comparisons were done using chi-square test. Multivariate logistic regression was used to obtain the significant determinants of smoking. A P students participated in the study with a response rate of 89.2%. The mean age (years) was 21.4 ± 3. Rate of ever smoking and current smoking was 9.6 and 1.2%, respectively. Age > 21, having a smoking father, and use of alcohol were significantly associated with ever smoking. Knowledge of smoking as a risk for emphysema was 72.8%, coronary artery disease 82.8%, stroke 68.8%, and low birth weight 76.4%. There were 103 (41.2%) students aware of antidepressant usage in smoking cessation. One hundred and ninety-five (78%) offered smoking cessation advice if a smoker had no smoking-related disease and did not seek their opinion about smoking, 68.8% affirmed to having adequate knowledge on smoking cessation, and 56.8% had received formal training on smoking cessation techniques. The ban on cigarette smoking in enclosed public places was supported by 92.4%. The prevalence of current cigarette smoking among medical students in Lagos is relatively low. Gaps exist in the level of knowledge of the students regarding risks of cigarette smoking, tobacco cessation strategies, and in their attitude and behavior towards offering tobacco cessation advice. There is need therefore to include formal training on tobacco control strategies at an early stage in the medical curriculum.

    Lung cancer is the most preventable neoplastic disease for men and women. The incidence rate per year is 14.000 in Germany. Smoking is the main risk factor for the onset of lung cancer and for a share of 90% of cases, lung cancer is associated with smoking. Recent studies have shown that the time slot of diagnosing lung cancer is a teachable moment for tobacco cessation interventions. The therapy that was rated most effective was a combination of cognitive behavioral therapy and pharmacotherapy (e. g. NRT, Bupropion, Varenicline). We examined the smoking status of all patients undergoing lung cancer surgery in 2011, 2012 and 2013 in this study. A retrospective semi structured interview via telephone was conducted regarding smoking habits and current quality of life. 131 patients (36.6% female, average age of 68.7 years) of an urban German hospital were included.Results showed a relapse rate of 22.3%, while 86.2% used to be highly addicted smokers; A multivariate analysis of covariance (MANCOVA) indicated a significant overall impact of smoking status on quality of life with a medium effect size, controlled for age, gender, living conditions, tumor stage, duration of smoking abstinence, type of cancer therapy, type of resection method, and the time period between the date of surgery and of the survey. Two thirds of all smokers did not see an association between their habit and their disease.So far motivation to quit and long term abstinence rates are not sufficiently established even among seriously sick patients in Germany; further initiatives should focus on new and more intense interventions and educational strategies.

    While cigarette smoking is a well-recognized cause of elevated white blood cell (WBC) count, studies on longitudinal effect of smoking cessation on WBC count are limited. We attempted to determine causal relationships between smoking and elevated WBC count by retrospective cross-sectional study consisting of 37,972 healthy Japanese adults who had a health check-up between April 1, 2008 and March 31, 2009 and longitudinal study involving 1730 current smokers who had more than four consecutive annual health check-ups between April 1, 2007 and March 31, 2012. In the cross-sectional study, younger age, male gender, increased body mass index, no alcohol habit, current smoking, and elevated C-reactive protein level were associated with elevated WBC count. Among these factors, current smoking had the most significant association with elevated WBC count. In subgroup analyses by WBC differentials, smoking was significantly associated with elevated counts of neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Ex-smoking was not associated with elevated WBC count. In the longitudinal study, both WBC and neutrophil counts decreased significantly in one year after smoking cessation and remained down-regulated for longer than next two years. There was no significant change in either WBC or neutrophil count in those who continued smoking. These findings clearly demonstrated that current smoking is strongly associated with elevated WBC count and smoking cessation leads to recovery of WBC count in one year, which is maintained for longer than subsequent two years. Thus, current smoking is a significant and reversible cause of elevated WBC count in healthy adults.

    Cigarette smoking in adolescent is a significant public health problem, leading to the risk of addiction, morbidity, and mortality in the long term. This study determined the prevalence and correlates of current smoking among adolescent school children. A nationwide school-based survey among 25 507 students between Forms 1 to 5 (aged 12-17) was conducted using a 2-stage cluster sampling design. The prevalence of current smoking was 11.5%. Multivariable logistic regression analysis revealed that current smoking was significantly associated with males (adjusted odds ratio [aOR] = 3.25; 95% confidence interval [CI] = 1.87, 4.98), current drinking (aOR = 2.34; 95% CI = 1.46, 3.74), drug used (aOR = 2.97; 95% CI = 1.24, 7.11), and being bullied (aOR = 1.41; 95% CI = 1.00, 1.98) at least once in the past 12 months. Smoking is associated with several behaviors that pose risks to adolescents, such as social issues and smoking-related health problems. Thus, early and integrated prevention programs that address multiple risk behaviors simultaneously are required.

    Previous studies have warned against the promoting effects of cigarette smoking on benign prostatic hyperplasia (BPH). In contrast, some have argued that smoking confers a protective effect regarding BPH, while others have observed an aggravated effect. Thus, we performed this meta-analysis to determine whether cigarette use is associated with BPH risk.To identify articles from observational studies of relevance, a search was performed concurrent to March 21, 2016, on PubMed, Web of Science, Cochrane, EBSCO, and EMBASE databases. Random-effect model, according to the heterogeneity, was calculated to reveal the relative risks (RRs) and corresponding 95% confidence intervals (CIs).Eight articles were included in this meta-analysis, representing data for 44,100 subjects, of which 5221 (11.8%) had BPH as defined according to the criteria. Seven reports are concerned with analysis between nonsmokers and ex-smokers, in which no significant difference was observed (RR = 0.99, 95% CI 0.94-1.05). Another meta-analysis of 7 studies indicated an observable trend, but without significant difference between groups of nonsmokers and current smokers (RR = 1.17, 95% CI 0.98-1.41). Between groups of heavy (6 articles; RR = 1.02, 95% CI 0.84-1.24) and light smokers (5 articles; RR = 0.90, 95% CI 0.71-1.15), again no significant difference appears. Finally, we combined individuals as never-smokers and ever-smokers and still found no significant difference between the 2 groups of patients (RR = 1.03, 95% CI 0.92-1.15). Sensitivity analysis was displayed and confirmed the stability of the present results.Combined evidence from observational studies shows no significant association between cigarette smoking and BPH risk, either for ex-smokers or for current smokers. The trend of elevated BPH risk from smoking was observed only in current smokers compared with nonsmokers, while marginal significance was observed in comparing ever-smokers with never-smokers in

  7. The crucial role of habits in energy consumption: an evolutionary approach on changing current patterns

    A substantial body of literature has shown that our behaviour is often guided by habits. The existence of habits - not fully conscious forms of behaviour - is important as it contradicts rational choice theory. Their presence thus calls for the setting of new instruments as they make it unlikely that consumers be capable of exercising control over their energy consumption in reaction to given incentives. This is further increased in the evolutionary perspective where the current carbon-based Socio-Technical System constraints and shapes consumers' choices through structural forces. Habits being potentially 'counterintentional', they may explain the 'efficiency paradox' in energy as well as the continued increase of energy consumption despite the rising environmental awareness among the population. Policies aiming at reducing energy consumption should thus specifically address the performance context of habits. For instance, targeting new residents has proven to be more effective given that their preceding habits have been disturbed. The results of our empirical analysis confirm this idea by showing how a change of context makes people more receptive to a proposed measure. Our analysis of the role played by habits also suggests that individuals do not consider the need to change existing habits as an obstacle even though this is contradicted implicitly in the answers they provided to open questions. This 'unconsciousness' is one of the most delicate features of habits and it should thus be accounted for when designing measures. Given the other characteristics of habits, the joint use of feedbacks and commitment strategies appears promising.

    To analyze the effects of age, sex, and media messages that encourage or discourage smoking, in conjunction with having 1 or more parents, close friends, teachers, or family members who smoke, on differences in patterns of adolescent smoking. This research is based on Croatian responses to the 2011 Global Youth Tobacco Survey. A total of 4245 Croatian youths responded to the Global Youth Tobacco Survey, of which individuals 3551 were aged 13 to 15 years. Of this cross section, 1644 individuals were male; 1856 were female; and 51 were of unknown sex. There were significant differences among responses in terms of age. Older adolescents were more likely to smoke (P youths who reported that they smoke have parents who smoke at home and have close friends who smoke; having a close or best friend who smokes is the highest prediction factor that both male and female youths will begin smoking. The majority of nonsmokers and smokers have never seen pro-smoking messages when going to concerts or during other community and social events. This lack of exposure to smoking-related advertising is the result of new legal restrictions imposed in 2008 on tobacco-product producers. There is no statistical significance among smokers' and nonsmokers' perceptions of antismoking media messaging. Peer pressure has been shown to be the second-most influential factor, after having a best friend who smokes, for the likelihood that an individual will become a smoker, among both male and female adolescents.

    We assessed the prevalence of alcohol consumption and smoking in Greek adolescents and evaluated their association with food habits. Adolescents (495 boys and 508 girls) aged 15 ± 1 years old and 15 ± 2 years old respectively, completed questionnaires regarding smoking, alcohol and food habits. Tobacco use and alcohol consumption were reported by 9.2% and 48.1% of them, respectively. Of those that drank alcohol, 13.9% were also smokers. Older adolescents were more likely to consume foods high in fat and sugar, low in vitamins and minerals as well as foods, considered by them to be less healthy and prepared in a less healthy way. Moreover, smoker adolescents were less likely to choose foods considered to be healthy and prepared in a healthy way, whereas they were more likely to choose foods high in fat content. Both smoking and alcohol consumption may affect cardiovascular risk and the vasculature. Poor lifestyle (and risk of vascular events) can start at an early age.

    The prevalence and social and health aspects of smoking habits among physicians of the Hospital San Pedro de Alcántara (Cáceres) were evaluated with the questionnaire used in the course on smoking habits delivered by the INSALUD in 1988. The sample consisted of 123 physicians. 47.1% (+8.7%) declared to be smokers. This prevalence is higher than that in the general population. The rate of female nonsmokers was significantly higher than that of male nonsmokers (p less than 0.05). 51.7% of smokers had not made any attempt to give up smoking. 90% thought that the role of the doctors as a model is important, and that the health system should undertake their treatment. 97.2% declared to lack therapeutic resources. The results disclose the need for specific programs directed to exemplary groups of professionals, such as those devoted to health care, so as to achieve a reduction in the smoking habit.

    Full Text Available Background: A variety of oral mucosal lesions and conditions are associated with the habit of smoking and chewing tobacco, and many of these carry a potential risk for the development of cancer. There have been no studies that report the prevalence of habits and associated oral changes in the population in Dharwad region, of Karnataka, south India. Materials and Methods: A hospital-based, cross-sectional study was carried out at SDM Dental College (Dharwad, Karnataka. A total of 2400 subjects (1200 subjects with and 1200 subjects without habits attending the dental hospital were interviewed and examined by trained professionals to assess any oral mucosal changes. Results: Oral mucosal lesions were found in 322 (26.8% subjects who had tobacco smoking and chewing habits as compared to 34 (2.8% subjects without those habits. Oral leukoplakia (8.2% and oral submucous fibrosis (OSF (7.1% were the prevalent oral mucosal lesions found in subjects who had those habits, while the other lesions (1.7% namely; oral candidiasis, median rhomboid glossitis, recurrent apthous ulcer, frictional keratosis, and oral lichen planus (0.9% were frequently reported among individuals without those habits. The odds of developing oral lesions in subjects with tobacco habits was nearly 11.92 times that of abstainers (odds ratio, OR = 11.92, 95% confidence intervals, CI = 10.61-14.59%. Conclusion: The study showed that the risk of the development of oral lesions associated with tobacco smoking, chewing, or both is quite high. Males who had one or more of these habits showed more frequent oral changes than females. The study reinforces the association of OSF with gutkha and areca nut chewing, and leukoplakia, erythroplakia, and oral cancer with tobacco smoking, chewing, or mixed habits.

    Tobacco use is the leading cause of noncommunicable disease morbidity and mortality. Most smokers initiate the smoking habit as adolescents or young adults. Survey data from the 2007 Lusaka (Zambia) Global Youth Tobacco Survey were used to estimate the prevalence of current cigarette smoking and assess whether exposure to pro-tobacco media and perception of the potential harm of secondhand smoke are associated with adolescents' smoking. Logistic regression analysis was used to estimate the associations. Altogether, 2378 students, of whom 56.8% were females, participated in the study. Overall, 10.5% of the students (9.3% among males and 12.1% among females) smoked cigarettes in the 30 days prior to the survey. Students who favored banning smoking in public places were 33% (OR = 0.67; 95% CI [0.47, 0.96]) less likely to smoke cigarettes compared to those who were not in favor of the ban. Seeing actors smoking in TV shows, videos or movies was positively associated with smoking (OR = 1.90; 95% CI [1.26, 2.88]). However, possessing an item with a cigarette brand logo on it, seeing advertisements of cigarettes on billboards and being ever offered a free cigarette by a cigarette sales representative were negatively associated with smoking (OR=0.39, 95% CI [0.26, 0.58]; OR=0.63, 95% CI [0.43, 0.92]; and OR=0.43, 95% CI [0.29, 0.65], respectively). Findings from this study indicate that TV advertisement-promotion-sponsorship was positively associated with smoking, while it was the opposite with other forms of advertisement; there is a need for further studies.

    Full Text Available The aim of this study was to examine whether there are social disparities in who receives questions and advice on smoking habits when visiting primary care and whether these disparities can be explained by differences in smoking habits. The study is based on 30,188 individuals aged 16–84 years who responded to a population survey questionnaire in 2012 in four counties in mid-Sweden (response rate 51%. Multivariate logistic regression models were used in statistical analyses. A total of 32% of those who visited a health care centre during the last three months reported that they were asked about their smoking habits during their latest visit, 6% received advice. In general, daily smokers received more often questions, and especially advice, than non-smokers. Persons with low education received more advice than persons with high education due to higher smoking prevalence. However, persons on disability pension and the unemployed were less frequently asked about their smoking habits than employees even though they smoke more. Women received less often questions and advice than men. Persons born outside the Nordic countries received advice twice as often as native Swedes regardless of whether they were daily smokers or not. In Sweden, those who are asked and, in particular, receive advice about changing their smoking habits while visiting primary care are mainly those who need it most. But the findings also imply that measures to reduce smoking should be intensified for women and are perhaps too intense for persons born outside the Nordic countries.

    Fluorimetric method based on oxidation of the fluorogenic 6-methoxy-2-naphthaldehyde was applied to evaluate temporal and population variability of the specific activity of salivary aldehyde dehydrogenase (ALDH) and the degree of its inactivation in healthy human population. Analyzed was also its dependence on drinking and smoking habits, coffee consumption, and its sensitivity to N-acetylcysteine. Both the specific activity of salivary ALDH and the degree of its inactivation were highly variable during the day, with the highest activities recorded in the morning hours. The activities were also highly variable both intra- and interpersonally, and negatively correlated with age, and this correlation was stronger for the subgroup of volunteers declaring abstinence from alcohol and tobacco. Moderately positive correlations of salivary ALDH specific activity with alcohol consumption and tobacco smoking were also recorded (r(s) ~0.27; p=0.004 and r(s) =0.30; p=0.001, respectively). Moderate coffee consumption correlated positively with the inactivation of salivary ALDH, particularly in the subgroup of non-drinking and non-smoking volunteers. It was found that mechanical stimulation of the saliva flow increases the specific activity of salivary ALDH. The specific activity of the salivary ALDH was strongly and positively correlated with that of superoxide dismutase, and somewhat less with salivary peroxidase. The antioxidant-containing drug N-acetylcysteine increased activity of salivary ALDH presumably by preventing its inactivation in the oral cavity. Some food-related aldehydes, mainly cinnamic aldehyde and anisaldehyde, were excellent substrates of the salivary ALDH3A1 enzyme, while alkenals, particularly those with short chain, were characterized by lower affinity towards this enzyme but high catalytic constants. The protective role of salivary ALDH against aldehydes in food and those found in the cigarette smoke is discussed, as well as its participation in

    From a structured history of 32 current smokers seen in the pulmonary function laboratory of a community hospital, we determined the number of cigarettes they smoked in 24 h. We also asked them to estimate their cigarette butt lengths from a visual model and to collect all cigarette butts over the next 24 h and mail them to us. We counted the butts, individually measured their lengths, and compared these with their previous estimates in order to validate their claims. While in the laboratory, we determined the level of carboxyhemoglobin in the peripheral blood of each patient. Patients tended to estimate the numbers of cigarettes that they smoked in units of five. Light smokers returned more butts and heavy smokers returned fewer butts than the numbers they reported as usually smoking. All patients were able to precisely estimate the average length of their cigarette butts, and they left butts of consistent lengths. There was no association between the numbers of cigarettes smoked and the butt lengths. Carboxyhemoglobin levels were positively associated with the numbers of cigarettes smoked in 24 h and negatively associated with the butt length and the time elapsed since the last cigarette was smoked, but these were not associated with the amount of tar in the cigarettes or with the number of years the person had smoked.

    The study reports the prevalence of cigarette smoking among 11401 high school Sardinian students. The prevalence of smokers (40.2%) significantly differs between gender (41.1% males and 38.4% females). Males have an early initiation of smoking with an evident addictive effect by age. 54.3% are daily smokers and 21.4% smoke 15 or more cigarettes per day. More than 50% smoke to look grown-up and to be accepted by the group. Besides age (OR=1.10; 95%CI: 1.06-1.15), other factors are associated with smoke: low education level of father (OR=1.08; 95%CI: 1.02-1.15), no maternal support (OR = 1.73; 95%CI: 1.17-2.54), to have at least one smoker cohabitant (OR=1.66; 95%CI: 1.54-1.80) and alcohol drinking (OR=3.46; 95%CI: 3.04-3.93). The smokers' knowledge on smoke topics significantly differ from non smokers. Our results suggest the need of community preventive interventions, diversified for specific target populations, to modify the students' behaviours so that they respect their own health and that of their fellow citizens.

    Given the increased prevalence of non-daily smoking and changes in smoking patterns, particularly among young adults, we examined correlates of smoking level, specifically motives for smoking, and readiness to quit smoking among 2682 college undergraduates who completed an online survey. Overall, 64.7% (n = 1736) were non-smokers, 11.6% (n = 312) smoked 1-5 days, 10.5% (n = 281) smoked 6-29 days and 13.2% (n = 353) were daily smokers. Ordinal regression analyses modeling smoking level indicated that correlates of higher smoking level included having more friends who smoke (β = 0.63, 95% CI 0.57-0.69) and more frequent other tobacco use (β = 0.04, 95% CI 0.02-0.05), drinking (β = 0.04, 95% CI 0.02-0.07) and binge drinking (β = 0.09, 95% CI 0.06-0.13). Bivariate analyses indicated that daily smokers (versus the subgroups of non-daily smokers) were less likely to smoke for social reasons but more likely to smoke for self-confidence, boredom, and affect regulation. Controlling for sociodemographics, correlates of readiness to quit among current smokers included fewer friends who smoke (P = 0.002), less frequent binge drinking (P = 0.03), being a social smoker (P < 0.001), smoking less for self-confidence (P = 0.04), smoking more for boredom (P = 0.03) and less frequent smoking (P = 0.001). Specific motives for smoking and potential barriers to cessation particularly may be relevant to different groups of college student smokers.

    Full Text Available Objectives. To compare prevalence estimates and assess issues related to the measurement of adult cigarette smoking in the National Health Interview Survey (NHIS and the National Survey on Drug Use and Health (NSDUH. Methods. 2008 data on current cigarette smoking and current daily cigarette smoking among adults ≥18 years were compared. The standard NHIS current smoking definition, which screens for lifetime smoking ≥100 cigarettes, was used. For NSDUH, both the standard current smoking definition, which does not screen, and a modified definition applying the NHIS current smoking definition (i.e., with screen were used. Results. NSDUH consistently yielded higher current cigarette smoking estimates than NHIS and lower daily smoking estimates. However, with use of the modified NSDUH current smoking definition, a notable number of subpopulation estimates became comparable between surveys. Younger adults and racial/ethnic minorities were most impacted by the lifetime smoking screen, with Hispanics being the most sensitive to differences in smoking variable definitions among all subgroups. Conclusions. Differences in current cigarette smoking definitions appear to have a greater impact on smoking estimates in some sub-populations than others. Survey mode differences may also limit intersurvey comparisons and trend analyses. Investigators are cautioned to use data most appropriate for their specific research questions.

    Tobacco smoking remains the leading causes of preventable morbidity and mortality in the world, requiring intensified national and international public health response. World Health Organization (WHO) has urged health professional organizations to encourage and support their members to be models for not using tobacco products and promote tobacco-free culture. Healthcare students are the future authority of the health society, they are in a position to play a vital role and have impact on social norms related to smoking. To determine the prevalence of tobacco smoking among healthcare students of Medical Faculty, University of Prishtina in Kosovo, so that recommendations can be made for its cessation among healthcare providers and thereafter the community. Descriptive cross-sectional study was conducted using self-administrated questionnaire prepared for this purpose. A total of 284 first year healthcare students of Medical Faculty, University of Prishtina in Kosovo were enrolled in the study. The data were analyzed using SPSS 22. All respondents completed the questionnaire, giving a response rate of 100% (general medicine=180, dentistry = 104). The prevalence of students who have ever smoked was 53.2%. However, only 8.9% (9.1% M vs. 8.7% F) of the general medicine students and 5.8% (4.8% M vs. 6.5% F) of dentistry students declared that smoke tobacco every day. Overall, the research shows that the prevalence of occasional smokers among medical students in Kosova is quite high.

    Background: acne vulgaris, is one of the most common skin disorder. Previous studies about the role of smoke in the pathogenesis of acne reported contradictory results. The aim of this study was to conduct a case-control study investigating the relationship between tobacco smoking and acne.

    Methods: a case-control study was performed during the period September 2009 - February 2010. A questionnaire was administrated to each participant, to assess the association acne - smoke. Cases were outpatients of the Dermatologic Ambulatory of the “Fiorini” Hospital, Sapienza University of Rome (Italy. Controls were age and gender-matched to the cases. The ratio cases-controls was 1:2. A univariate and a multiple logistic regression analysis were conducted; Odds Ratio (OR and the relative 95% confidence interval (95%CI were assessed. The statistical significance was set at p < 0.05.

    Results: crude OR for the association acne - smoke was 7.26 (IC=2.27-23.18; adjusted OR for sex and age was 5.47 (IC=1.67-17.97. Of 93 cases, 6 had a severe grade of acne (6.5%, 19 had an intermediate grade of acne (20.4%, and 68 had a mild grade of acne (73.1%. No one of the smokers had a severe grade of acne, one had an intermediate grade of acne and 11 had mild acne; these differences are not statistically significant.

  12. Habits of employees”: smoking, spies, and shopfloor culture at Hammermill Paper Company.

    2011-01-01

    As cigarette smoking expanded dramatically during the early twentieth century, it brought more and more workers into conflict with the policies and demands of the manufacturers who employed them. As this paper shows, addiction to nicotine ignited daily struggles over workers’ shopfloor rights and the ability of employers to set rules, establish discipline, and monitor behavior. A specific set of records from the archives of the Hammermill Paper Company, a paper manufacturer once based in Erie, Pennsylvania, provide a unique opportunity to explore the impact of cigarette consumption on labor relations during the era of mass production, as two nosy factory spies probed and documented worker actions and attitudes in the summer of 1915. As a result of their intelligence gathering, the spies discovered a factory-wide work culture rooted in the addictive pleasure of cigarette smoke. This discovery worried them. Worker-smokers needed to dampen their hunger for nicotine with frequent, and often clandestine, breaks from work, typically in defiance of “no-smoking” rules, employer designations for the uses of factory space, and bosses’ demands for continuous production. Highlighting the intersections of the histories of labor, smoking, and addiction, this paper argues that cigarettes were a key battleground in workers’ and managers’ intensifying struggles over who really controlled the industrial shopfloor during the early 1900s.

    The long-chain polyunsaturated fatty acids are considered to be of major health importance, and recent studies indicate that their endogenous metabolism is influenced by B-vitamin status and smoking habits. We investigated the associations of circulating B-vitamins and smoking habits with serum polyunsaturated fatty acids among 1,366 patients who underwent coronary angiography due to suspected coronary heart disease at Haukeland University Hospital, Norway. Of these, 52% provided information on dietary habits by a food frequency questionnaire. Associations were assessed using partial correlation (Spearman's rho). In the total population, the concentrations of most circulating B-vitamins were positively associated with serum n-3 polyunsaturated fatty acids, but negatively with serum n-6 polyunsaturated fatty acids. However, the associations between B-vitamins and polyunsaturated fatty acids tended to be weaker in smokers. This could not be solely explained by differences in dietary intake. Furthermore, plasma cotinine, a marker of recent nicotine exposure, showed a negative relationship with serum n-3 polyunsaturated fatty acids, but a positive relationship with serum n-6 polyunsaturated fatty acids. In conclusion, circulating B-vitamins are, in contrast to plasma cotinine, generally positively associated with serum n-3 polyunsaturated fatty acids and negatively with serum n-6 polyunsaturated fatty acids in patients with suspected coronary heart disease. Further studies should investigate whether B-vitamin status and smoking habits may modify the clinical effects of polyunsaturated fatty acid intake.

    Background: Waterpipe smoking (WPS) is widely believed to be a safe and hazard-free tobacco habit. However, a number of studies have indicated that exposure to several toxicants and carcinogens through WPS is strongly related to serious health hazards. The current paper presents a narrative review on the effects of WPS on cancer outcome. Methods: The addressed focused question was “Is there an association between waterpipe smoking and cancer outcome?” PubMed, Medline, EMBASE, ISI Web of Science and the Cochrane databases were searched until June 2015 using the key words “Waterpipe”, “Hookah”, “Narghileh”, “Shisha”, “Hubbly Bubbly” “cancer” in various combinations. Letters to the Editor, review articles, case-reports and unpublished articles were excluded. Results: A total of 16 studies were included: six on lung cancer, three on oesophageal cancer, two on gastric cancer, two on bladder cancer, and one each on nasopharyngeal, pancreatic and prostate cancers. Our search did not yield any study that evaluated the risk of oral cancer in WPS users. The available evidence showed a significant association of WPS with lung cancer (UOR 6.0, 95% CI 1.78–20.26); however, no association was observed with bladder, nasopharyngeal, pancreatic and prostate cancers. Gastric (OR 3.4, 95% CI 1.7-7.1) and oesophageal cancers (OR 1.85, 95% CI 1.41-2.44) were observed to have weak associations with WPS. Conclusion: Regardless of the limitations, there is sufficient evidence to suggest associations of WPS with cancer, particularly in the lung. Future well-designed studies are required to identify and quantify with confidence all the health effects of this form of smoking. Creative Commons Attribution License

  15. Transcranial Direct Current Stimulation and behavioral models of smoking addiction

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available While few studies have applied transcranial direct current stimulation (tDCS to smoking addiction, existing work suggests that the intervention holds promise for altering the complex system by which environmental cues interact with cravings to drive behavior. Imaging and repetitive transcranial magnetic stimulation (rTMS studies suggest that increased dorsolateral prefrontal cortex (DLPFC activation and integrity may be associated with increased resistance to smoking cues. Anodal tDCS of the DLPFC, believed to boost activation, reduces cravings in response to these cues. The finding that noninvasive stimulation modifies cue induced cravings has profound implications for understanding the processes underlying addiction and relapse. TDCS can also be applied to probe mechanisms underlying and supporting nicotine addiction, as was done in a pharmacologic study that applied nicotine, tDCS, and TMS paired associative stimulation to find that stopping nicotine after chronic use induces a reduction in plasticity, causing difficulty in breaking free from association between cues and cravings. This mini-review will place studies that apply tDCS to smokers in the context of research involving the neural substrates of nicotine addiction.

    2014-09-01

    Full Text Available Despite 50+ years of public health efforts to reduce smoking rates in the United States, approximately one-fifth of the adults living in this country continue to smoke cigarettes. Previous studies have examined smokers’ risk perceptions of cigarette smoking, as well as the perceived benefits of quitting smoking. Less research has focused on the perceived benefits of smoking among current cigarette smokers. The latter is the main focus of the present paper. Questionnaire-based interviews were conducted with a community-based sample of 485 adult current cigarette smokers recruited from the Atlanta, Georgia, metropolitan area between 2004 and 2007. Active and passive recruiting approaches were used, along with a targeted sampling strategy. Results revealed that most current cigarette smokers perceive themselves to experience benefits as a result of their cigarette use, including (among others increased relaxation, diminished nervousness in social situations, enjoyment of the taste of cigarettes when smoking, and greater enjoyment of parties when smoking. Perceiving benefits from cigarette smoking was associated with a variety of tobacco use measures, such as smoking more cigarettes, an increased likelihood of chain smoking, and overall negative attitude toward quitting smoking, among others. Several factors were associated with the extent to which smokers perceived themselves to benefit from their tobacco use, including education attainment, the age of first purchasing cigarettes, the proportion of friends who smoked, hiding smoking from others, being internally-oriented regarding locus of control, and self-esteem.

    Wastewater analysis is a powerful method that can provide useful information about the abuse of legal and illicit drugs. The aim of our study was to determine nicotine consumption during four different music festivals and to find a connection between smoking and preferences for specific music styles using wastewater analysis. The amount of the nicotine metabolite cotinine was monitored in wastewater at the influent of three waste water treatment plants WWTPs in the Czech Republic and Slovakia, where the festivals took place. Urinary bio-markers of nicotine utilization were analyzed by LC-HRMS. More than 80,000 festival participants were monitored during our study from June to September 2014. A significant increase of nicotine consumption was observed in wastewaters during music festivals. The nicotine ingestion level was back-calculated and expressed as mass of pure drug consumed per day and per 1000 inhabitants for selected cities of both countries. The highest differences between typical levels of cotinine in wastewaters and the levels during music festivals were detected in Piešťany: 4 g/L/1000 inhabitants during non-festival days compared to 8 g/L/1000 inhabitants during the Topfest pop-rock festival and 6g/L/1000 inhabitants during the Grape dance festival. No significant increase of the amounts of cotinine in wastewater was recorded for the Country and Folk festivals.

    Tobacco use is the leading cause of preventable disease and death in the United States, and cigarettes are the most commonly used tobacco product among U.S. adults (1,2). To assess progress toward achieving the Healthy People 2020 target of reducing the proportion of U.S. adults who smoke cigarettes to ≤12.0% (objective TU1.1),* CDC assessed the most recent national estimates of cigarette smoking prevalence among adults aged ≥18 years using data from the 2015 National Health Interview Survey (NHIS). The proportion of U.S. adults who smoke cigarettes declined from 20.9% in 2005 to 15.1% in 2015, and the proportion of daily smokers declined from 16.9% to 11.4%. However, disparities in cigarette smoking persist. In 2015, prevalence of cigarette smoking was higher among adults who were male; were aged 25-44 years; were American Indian/Alaska Native; had a General Education Development certificate (GED); lived below the federal poverty level; lived in the Midwest; were insured through Medicaid or were uninsured; had a disability/limitation; were lesbian, gay, or bisexual; or who had serious psychological distress. Proven population-based interventions, including tobacco price increases, comprehensive smoke-free laws, anti-tobacco mass media campaigns, and barrier-free access to tobacco cessation counseling and medications, are critical to reducing cigarette smoking and smoking-related disease and death among U.S. adults, particularly among subpopulations with the highest smoking prevalences (3).

    Full Text Available Abstract Background Serum selenium level (s-Se has been associated with prostate cancer (PrCa risk. We investigated the relation between s-Se, smoking and non-screening detected PrCa and explored if polymorphisms in two DNA repair genes: OGG1 and MnSOD, influenced any effect of s-Se. Methods ULSAM, a population based Swedish male cohort (n = 2322 investigated at age 50 for s-Se and s-Se influencing factors: serum cholesterol, erythrocyte sedimentation rate and smoking habits. At age 71 a subcohort, (n = 1005 was genotyped for OGG1 and MnSOD polymorphisms. Results In a 34-year-follow-up, national registries identified 208 PrCa cases further confirmed in medical records. Participants with s-Se in the upper tertile had a non-significantly lower risk of PrCa. Smokers with s-Se in the two lower tertiles (≤80 μg/L experienced a higher cumulative incidence of PrCa than smokers in the high selenium tertile (Hazard Ratio 2.39; 95% CI: 1.09-5.25. A high tertile selenium level in combination with non-wt rs125701 of the OGG1 gene in combination with smoking status or rs4880 related variation of MnSOD gene appeared to protect from PrCa. Conclusions S-Se levels and smoking habits influence long-term risk of PrCa. Smoking as a risk factor for PrCa in men with low s-Se is relevant to explore further. Exploratory analyses of variations in OGG1 and MnSOD genes indicate that hypotheses about patterns of exposure to selenium and smoking combined with data on genetic variation in genes involved in DNA repair can be valuable to pursue.

    AIM To analyze the association between oncohematological diseases and GSTT1/GSTM1/CYP1A1 polymorphisms, dietary habits and smoking, in an argentine hospital-based case-control study. METHODS This hospital-based case-control study involved 125 patients with oncohematological diseases and 310 control subjects. A questionnaire was used to obtain sociodemographic data and information about habits. Blood samples were collected, and DNA was extracted using salting out methods. Deletions in GSTT1 and GSTM1 (null genotypes) were addressed by PCR. CYP1A1 MspI polymorphism was detected by PCR-RFLP. Odds ratio (OR) and 95%CI were calculated to estimate the association between each variable studied and oncohematological disease. RESULTS Women showed lower risk of disease compared to men (OR 0.52, 95%CI: 0.34-0.82, P = 0.003). Higher levels of education (> 12 years) were significantly associated with an increased risk, compared to complete primary school or less (OR 3.68, 95%CI: 1.82-7.40, P tobacco, none of the smoking categories showed association with oncohematological diseases. Regarding dietary habits, consumption of grilled/barbecued meat 3 or more times per month showed significant association with an increased risk of disease (OR 1.72, 95%CI: 1.08-2.75, P = 0.02). Daily consumption of coffee also was associated with an increased risk (OR 1.77, 95%CI: 1.03-3.03, P = 0.03). Results for GSTT1, GSTM1 and CYP1A1 polymorphisms showed no significant association with oncohematological diseases. When analyzing the interaction between polymorphisms and tobacco smoking or dietary habits, no statistically significant associations that modify disease risk were found. CONCLUSION We reported an increased risk of oncohematological diseases associated with meat and coffee intake. We did not find significant associations between genetic polymorphisms and blood cancer.

    Full Text Available Laurence M GalantiClinique Universitaire UCL, Mont-Godinne, Yvoir, BelgiumAbstract: Tobacco smoking is widespread and is one of the world’s most prevalent modifiable risk factors for morbidity and mortality. It is important to facilitate smoking cessation better in order to reduce the health consequences of tobacco use. The most effective approach assisting smokers in their quit attempts combines both pharmacotherapy and nonpharmacological interventions. This review summarizes the latest international epidemiological data available on tobacco use, considers the associated effects on health, and reviews existing policies against tobacco use. Among the interventions for smoking cessation, the three major pharmacotherapies (which have demonstrated efficacy when combined with behavioral support are discussed: nicotine replacement therapy (NRT, bupropion, and varenicline. As the newest pharmacotherapy made available in this area, particular consideration is given to varenicline, and a review of our clinical experience is offered.Keywords: tobacco smoking cessation, nicotinic substitution, nicotine replacement therapy (NRT, bupropion, varenicline

    As most of the etiologic factors of malocclusion are of genetic origin and thus cannot be prevented, environmental causative factors have become the focus for correction. Early interception of oral habits may be an important step in order to prevent occlusal disturbances in children. The identification of an abnormal habit and the assessment of its potential immediate and long-term effects on the dentition and potentially on the craniofacial complex should be made at an early stage. This paper focuses on the most common oral habits influencing dentofacial growth in childhood and management of these habits in the developing dentition.

    Full Text Available OBJETIVO: Avaliar a tendência temporal do tabagismo em estudantes de medicina nos últimos dez anos. MÉTODOS: Realizou-se estudo transversal com estudantes do primeiro ao quinto ano do curso de medicina, em 1996. A amostra foi de 449 alunos que responderam a questionário auto-aplicável. Fumante era aquele que fumava um ou mais cigarros por dia há pelo menos um mês; ex-fumantes foram aqueles que, no período da entrevista, não eram fumantes regulares, mas o haviam sido anteriormente. Pesquisa similar foi realizada em 1986 e 1991. RESULTADOS/CONCLUSÕES: A prevalência de tabagismo foi de 11%, comparada com 14% em 1991 e 21% em 1986. Apesar da redução do tabagismo nas três séries estudadas, a queda percentual entre 1996 e 1991 foi menor do que aquela observada entre 1991 e 1986. Em 1996, a prevalência do vício de fumar aumentou conforme o ano cursado. Não houve diferenças significativas quanto ao sexo. A maioria dos alunos mostrou-se favorável à proibição do fumo em locais de ensino e assistência e afirmaram que o tema era pouco valorizado no currículo da faculdade.OBJECTIVE: To evaluate trends in smoking habits among medical students in the last ten years. METHODS: In 1996, a cross-sectional survey of smoking habits was carried out among students in the first to the fifth year of medical school. Four hundred and nine students answered the questionnaire. A regular smoker was defined as someone who smokes one or more cigarettes a day at least for one month; former smokers were the ones who used to smoke in the past but not at the moment. Similar researchs were conducted in 1986 and 1991. RESULTS/CONCLUSIONS: Smoking prevalence was 11% compared with 14% in 1991 and 21% in 1986. Although there was a significant reduction of smoking in the last three years, the actual decrease from 1991 to 1996 was less than that observed from 1986 to 1991. In 1961, the prevalence of smoking increased in the last years of medical school. There

    Full Text Available Objectives: The purpose of this review was to evaluate whether history of periodontitis and smoking habits could represent a risk factor for peri-implantitis and implant loss. Material and Methods: This systematic review followed PRISMA guidelines and was registered at the PROSPERO database [registration numbers CRD42016034160 (effect of history of periodontitis and CRD42016033676 (effect of smoking]. Broad electronic (MEDLINE and manual searches were conducted among articles published from January 1st 1990 up to December 31st 2015, resulting in 49332 records for history of periodontitis and 3199 for smoking habits. Selection criteria included prospective studies comparing two cohorts of patients, with and without the investigated risk factor, with a minimum follow-up period of three years, and reporting data on peri-implantitis and implant loss occurrence. Considering that only prospective studies were included, dichotomous data were expressed as risk ratios and 95% confidence intervals. Results: Three studies evaluating history of periodontitis (on which quantitative analysis was performed and one study on smoking effect were included. Both implant and patient-based meta-analyses revealed a significantly higher risk of developing peri-implantitis in patients with a history of periodontitis compared with periodontally healthy subjects, but not a statistically significant increased risk for implant loss. Conclusions: The outcomes of this systematic review indicate history of periodontitis as a possible risk factor for peri-implantitis, while insufficient data are present in literature to evaluate the role of smoking. However, available evidence is still weak and immature, and sound epidemiological studies are needed to analyse the specific contribution of these potential risk factors.

    Premalignant oral lesions are usually associated with noxious oral addiction habits. These habits are common in both, high as well as low socioeconomic status but education status of parent and patients significantly affects the development of noxious oral addictions. A total of 872 patients (cases and controls) were included in the study. Social class was determined as per modified Prasad's classification (1970) with price index correction of 2004. Prevalence of lichen planus, to be only 0.4 and 2.6% present in groups III and IV of cases, and submucous fibrosis (SMF) - stromal one lanocytic foci - was 2.4% in male (group III) whereas it was not found in female cases (group IV). Teenagers having higher frequency and longer duration of noxious habits were more prone for development of premalignant lesions. 0.6% of leukoplakia, 0.3% erythroplakia, 0.7% lichen planus and 0.7% submucous fibrosis were present in 872 observed patients of control and cases.

    Full Text Available OBJECTIVE: The aim of this study was to analyze social characteristics and stress as correlates of cigarette smoking in adolescence. The main intent was to identify elements that distinguish adolescents who had experimented with smoking and did not progress to regular smoking from those who became current smokers. METHODS: Students at 10 high schools in the city of Ribeirão Preto, Brazil, completed a questionnaire based on an instrument employed in a similar large-scale study. The students were classified as never-smokers or experimenters. The experimenters were subcategorized as having become current smokers or nonprogressors. Analyses were performed using adjusted logistic models. RESULTS: A total of 2,014 students (mean age, 16.2 ± 1.1 years; females, 53% completed the questionnaire. We categorized 1,283 students (63.7% as never-smokers, 244 (12.1% as current smokers, and 487 (24.2% as nonprogressors. We found that experimentation with smoking was associated with being held back a grade in school (OR = 1.80, alcohol intake (low/occasional, OR = 8.92; high/regular, OR = 2.64, illicit drug use (OR = 9.32, having a sibling or cousin who smokes (OR = 1.39, having a friend who smokes (OR = 2.08, and high levels of stress (in females only, OR = 1.32. Factors associated with an increased risk of transitioning from experimenter to current smoker were alcohol intake (low/occasional, OR = 3.28; high/regular, OR = 2.16, illicit drug use (OR = 3.61, and having a friend who smokes (OR = 7.20. CONCLUSIONS: Current smoking was associated with a profile of socioeconomic correlates different from that associated with experimentation only. Our data (showing that current smoking was associated with having a friend who smokes, alcohol intake, and illicit drug use suggest the need for comprehensive approaches to discourage substance use during adolescence.

The goal of the research is that: to identify the taxonomic composition of game species and make full list of species to assess the current state of populations and resources to carry out eco-faunistic analysis of the distribution of game mammals habiting Shelkovskiy district of Chechnya. Methods. We used mapping techniques, various methods of census forms and scientific processing of the collected material, systematic and bioecological analysis. Results. As a result, we have identified 5 ecological complexes and characterized them by distribution on the identified and described natural habitats. We have made an inventory of species, identified conditions of rare species and determined their status. Biometric data has been obtained for a number of species; their biological and ecological features have been described. We also identified the species composition of game mammals and their spatial distribution of habitats. The differentiation of species in ecological groups has been carried out. Data has been obtained on the number of nine major types for the period of 2012-2013, and their characteristics. We have made an estimation of ecological and economic potential of resources of game mammals of the study area. Conclusions. Based on the analysis of the results we can make a judgment about the level of biodiversity of species of game mammals of the studied area, the current state of their number and possible use for commercial, sports and recreational purposes. We propose specific measures such as the use of existing biological resources i.e. species of mammals, as well as the creation of new protected areas as a form of preserving and increasing the number of mammals in the area. The research results can be useful for monitoring and creating specially protected natural reservations, protection of endangered species. The findings have implications for the organization of hunting economy to increase the number of game animals.

    Full Text Available CONTEXT AND OBJECTIVE: Recent studies have shown regional and population differences in semen characteristics. The objective was to establish reference values for semen analysis and to verify the effect that age, length of sexual abstinence, seasonality, smoking habits and coffee consumption have on fertile individuals’ semen characteristics. DESIGN AND SETTING: Prospective study in the Urology Division, Hospital das Clínicas, Universidade de São Paulo. METHODS: Between September 1999 and August 2002, 500 fertile men requesting a vasectomy for sterilization purposes were asked to provide a semen sample before the vasectomy. We evaluated the effects of age, sexual abstinence, seasonality, smoking and coffee consumption on semen characteristics. RESULTS: Compared with World Health Organization values, 87.2% of the patients presented sperm morphology below the normal level. A significant decline in semen volume, sperm motility and sperm morphology in patients over 45 years of age was observed. In patients with 5 days or more of abstinence, there was reduced sperm motility. The lowest values for sperm concentration, motility and morphology were observed in summer and the highest in winter. No differences in semen parameters relating to smoking were detected. Patients who drank six or more cups of coffee per day presented higher sperm motility. CONCLUSIONS: Our sample had a very low percentage of normal sperm morphology. Only sperm morphology showed a high abnormality rate. Differences in semen parameters with regard to age, length of sexual abstinence, seasonality and coffee consumption were identified. No differences relating to smoking were detected.

    As a physiological condition closely linked with increased susceptibility to oxidative stress, pregnancy can be further compromised by cigarette smoking. Inadequate nutrition and reduced intake of antioxidants can also disrupt the prooxidant/antioxidant relationship and contribute to oxidative stress. Increased oxidative stress during pregnancy may be involved in several complications of pregnancy, such as preterm labor, fetal growth restriction, preeclampsia and miscarriage. The aim of this study was to investigate the influence of maternal smoking habits before pregnancy on the parameters of oxidative stress and the antioxidative defense system, lipid profile parameters and paraoxonase-1 (PON1) activity during the third trimester of uncomplicated pregnancies. Healthy pregnant women (n = 86) were divided into non-smoking and smoking groups, and into groups taking vitamin supplements and not taking them. Oxidative damage was measured through the levels of thiobarbituric acid-reacting substances (TBARS) and plasma antioxidant status was evaluated by measuring total antioxidant capacity (TAC). TBARS concetration was significantly higher (p pregnancy is associated with increased oxidative stress. Vitamin supplementation has no effect on the oxidative stress status of healthy pregnant women.

    Women with a pregnancy complicated by preeclampsia, intra-uterine growth restriction and/or gestational diabetes are at increased risk of future cardiovascular and metabolic disease. Lifestyle intervention may help these women to effectively lower these risks. To test if offering lifestyle intervention after a complicated pregnancy significantly improves saturated fat-intake and exercise (primary objectives) and/or smoking habits (secondary objective). The Pro-Active study (Postpartum Rotterdam Appraisal of Cardiovascular health and Tailored Intervention) is a feasibility study to develop and evaluate a postpartum lifestyle intervention program. In a prospective case-control setting we tested the effect of the lifestyle intervention. Women were included between April 2007 and August 2009. They were eligible if ⩾18 years old at time of inclusion, being able to understand and speak the Dutch language and not having pre-existing conditions that could interfere with the lifestyle intervention. Cases were offered lifestyle intervention by a trained counsellor between 6 and 10 months postpartum. During 3 private sessions, mainly exercise and fat-intake and to some extend smoking habits were discussed and aims were made to improve lifestyle. Controls did not receive these sessions, but were not restricted to improve lifestyle on their own. Lifestyle habits were scored at 6 and 13 months postpartum. For saturated fat-intake we used the Maastricht Fatlist. For exercise we used the International Physical Activity Questionnaire (IPAQ). For smoking habits we used a short version of the questionnaire of STIVORO (the Dutch anti-smoking association). We also performed a formative evaluation of the intervention program. During our study 1121 women gave birth after a complicated pregnancy. 490 Women were eligible for the study of which 240 women (49%) gave informed consent to participate. 56 Women (23%) were lost-to-follow-up, leaving 186 women for the analysis.

    Many brain regions are involved in smoking addiction (e.g. insula, ventral tegmental area, prefrontal cortex and hippocampus), and the manipulation of the activity of these brain regions can show a modification of smoking behavior. Low current transcranial direct current stimulation (tDCS) is a noninvasive way to manipulate cortical excitability, and thus brain function and associated behaviors. In this study, we examined the effects of inhibiting the frontal-parietal-temporal association area (FPT) on attention bias to smoking-related cues and smoking behavior in tobacco users. This inhibition is induced by cathodal tDCS stimulation. We tested three stimulation conditions: 1) bilateral cathodal over both sides of FPT; 2) cathodal over right FPT; and 3) sham-tDCS. Visual attention bias to smoking-related cues was evaluated using an eye tracking system. The measurement for smoking behavior was the number of daily cigarettes consumed before and after tDCS treatment. We found that, after bilateral cathodal stimulation of the FPT area, while the attention to smoking-related cues showed a decreased trend, the effects were not significantly different from sham stimulation. The daily cigarette consumption was reduced to a significant level. These effects were not seen under single cathodal tDCS or sham-tDCS. Our results show that low current tDCS of FPT area attenuates smoking cue-related attention and smoking behavior. This non-invasive brain stimulation technique, targeted at FPT areas, might be a promising method for treating smoking behavior.

    To estimate the prevalence of tobacco smoking among physiotherapy and nursing students at the University of the Balearic Islands in Spain and to describe their perceptions, attitude and behaviour towards smoking and towards the Spanish Smoking Prevention Act. Active smoking is the first avoidable cause of death in the world while passive smoking is the third. The tobacco epidemic kills 5.4 million people a year from lung cancer, heart disease and other related illnesses. In Europe, around one-third of the Community population are smokers, with about 650,000 smoking-related deaths per year in the Community. In Spain, 56,000 people a year are estimated to die from tobacco-related illnesses. An observational, cross-sectional, descriptive study, with a sample of 345 out of 645 students (53.5% participation rate) who completed an anonymous, self-administered, standardized survey devised by the World Health Organization. The study revealed a 26.1% prevalence of tobacco smoking (26.9% among women and 22.6% among men), which is similar to percentages of students at other Spanish universities. Smokers and non-smokers reported many differences in attitude and behaviour, some of which have potential repercussions in their career, such as in estimating the harmful effects of tobacco smoke or the status of health professionals as role models in the society they serve. The results of this study will contribute to develop an anti-smoking programme at the university and to establish smoking-prevention campaigns.

    Weight loss and reduced fat-free mass are prevalent amongst patients with chronic obstructive pulmonary disease (COPD). However, the causes of this weight loss are not clear. The aims of this study are to investigate the factors affecting body weight and dietary intake in a group of outpatients with COPD, and to investigate any differences between adequately nourished and malnourished patients. In 103 stable outpatients, nutritional status was assessed using Body Mass Index (BMI) and upper arm anthropometry. Lung function, smoking status, exercise tolerance, dietary intake, dietary problems and health-related quality of life were assessed. Patients were classed as either adequately nourished or malnourished. Twenty-three per cent of subjects were classed as malnourished. The malnourished subjects had lower lung function measurements, suffered more dietary problems and had lower nutritional intake compared with the adequately nourished subjects. They also had poorer fatigue scores. In linear regression analysis, the factors that had the most effect on BMI were a low transfer factor, presence of early satiety, and being a current smoker. Important differences were found between adequately nourished and malnourished subjects. These differences move us closer to understanding how best to screen and treat this group of patients.

    Asthma is a common chronic multifactorial disease that affects >300 million people worldwide. Outdoor and indoor pollution exposure has been associated with respiratory health effects in adults and children. Smoking still represents a huge public health problem and millions of children suffer the detrimental effects of passive smoke exposure. This study was designed to review the current evidences on exposure to passive smoke as a risk factor for asthma onset in childhood. A review of the most recent studies on this topic was undertaken to provide evidence about the magnitude of the effect of passive smoking on the risk of incidence of asthma in children. The effects of passive smoking are different depending on individual and environmental factors. Environmental tobacco smoke (ETS) is one of the most important indoor air pollutants and can interact with other air pollutants in eliciting respiratory outcomes during childhood. The increased risk of respiratory outcomes in children exposed to prenatal and early postnatal passive smoke might be caused by an adverse effect on both the immune system and the structural and functional development of the lung; this may explain the subsequent increased risk of incident asthma. The magnitude of the exposure is quite difficult to precisely quantify because it is significantly influenced by the child's daily activities. Because exposure to ETS is a likely cause for asthma onset in childhood, there is a strong need to prevent infants and children from breathing air contaminated with tobacco smoke.

The age range was 20-86 years. The influence in lip hydration levels of age, sex, phototype, size of the lips and smoking habits was studied using a Corneometer 825 (Courage & Khazaka Electronic GmbH, Cologne, Germany). An increase in lip hydration was found between the basal (53.49 +/- 15.259) and final (59.34 +/- 14.51) Corneometer 825 (Courage & Khazaka Electronic GmbH, Cologne, Germany) measurements over the three months of treatment, with statistically significant differences with respect to the control (p=0.002). However, no statistically significant differences in lip hydration were observed with regard to age, (p=0.48), gender (p=0.876), skin phototype (p=0.653), lip area (p=0.291) and smoking (p=0.178). Application of a lipstick sunscreen 3 times a day for 3 months increases lip hydration.

    Full Text Available OBJECTIVE: To describe the characteristics and associated factors of the smoking habit among older adults. METHODS: A population-based study was carried out comprising 1,606 (92.2% older adults (>60 years old living in the Bambuí town, Southeastern Brazil in 1997. Data was obtained by means of interview and socio-demographic factors, health status, physical functioning, use of healthcare services and medication were considered. The multiple multinomial logistic regression was used to assess independent associations between smoking habits (current and former smokers and the exploratory variables. RESULTS: The prevalence of current and past smoking was 31.4% and 40.2% among men, and 10.3% and 11.2% among women, respectively (p80 years and schooling (>8 years and positive association with poor health perception and not being married. Among women, independent and negative associations with current smoking were observed for age (75-79 and >80 years and schooling (4-7 and >8 years. CONCLUSIONS: Smoking was a public health concern among older adults in the studied community, particularly for men. Yet, in a low schooling population, a slightly higher level was a protective factor against smoking for both men and women. Programs for reducing smoking in the elderly population should take these findings into consideration.OBJETIVO: Descrever as características e fatores associados ao hábito de fumar em uma população idosa.

    The objective of the study was to determine the brand distribution of premium, discount, and native cigarette brands and to identify the factors associated with smoking these brands among a nationally representative sample of Canadian youth smokers. Data from 3,137 current smokers in Grades 9-12 participating in the 2008-2009 Youth Smoking Survey (YSS) were used to examine the prevalence and factors associated with different cigarette brand preferences. The most prevalent brand of cigarette smoked was premium cigarettes (44.7%), followed by discount cigarettes (33.7%), and to be native cigarettes (7.3%). There was significant variability in brand preference by province with the majority of youth in Atlantic Canada and Quebec smoking a discount brand of cigarettes and higher prevalence rates of native cigarette use in Ontario and Quebec. Respondents were more likely to smoke discount cigarettes if they were female, daily smokers, or if they only had $1-20 a week in spending money. Respondents were more likely to smoke native cigarettes if they were Aboriginal, heavier smokers, or if they reported having no weekly spending money. A significant proportion of students from Grade 9 to 12 in Canada smoke cigarettes that are more affordable than premium brands and it appears that the market share for these more affordable cigarette options has increased in recent years. Given that the price of cigarettes is an important determinant in youth smoking behavior, it is critical to develop and continue to enforce tobacco control strategies designed to eliminate access to cheaper sources of cigarettes among youth populations.

    No Smoking Day comes once a year. It calls on people to quit smoking, but there're still so many smokers in the world. Worse still, the number of smokers is increasing day by day. As we know, smoking is a bad habit. Smoking is harmful not only to a smoker himself but also to the people around. It is said that if you smoke one cigarette, your life will be a second shorter. In other words, smoking means buying death with money. I've learned from a newspaper that tens of thousands of people in the world die fr...

    Smoking is the number one modifiable environmental risk factor for chronic obstructive pulmonary disease (COPD). Clinical, epidemiological and increasingly "omics" studies assess or adjust for current smoking status using only self-report, which may be inaccurate. Objective measures such as exhaled carbon monoxide (eCO) may also be problematic owing to limitations in the measurements and the relatively short half life of the molecule. In this study, we determined the impact of different case definitions of current cigarette smoking on gene expression in peripheral blood of patients with COPD. Peripheral blood gene expression from 573 former- and current-smokers with COPD in the ECLIPSE study was used to find genes whose expression was associated with smoking status. Current smoking was defined using self-report, eCO concentrations, or both. Linear regression was used to determine the association of current smoking status with gene expression adjusting for age, sex and propensity score. Pathway enrichment analyses were performed on genes with P PID1, FUCA1, GPR15) with enrichment in 40 biological pathways related to metabolic processes, response to hypoxia and hormonal stimulus. Additionally, the combined definition provided better distributions of test statistics for differential gene expression. A combined phenotype of eCO and self report allows for better discovery of genes and pathways related to current smoking. Studies relying only on self report of smoking status to assess or adjust for the impact of smoking may not fully capture its effect and will lead to residual confounding of results. © The Author 2016.

    Understanding the role of the family in shaping adolescent health risk behaviours has recently been given increased attention. This study investigated association between current smoking and a range of familial factors in a representative sample of Lithuanian adolescents. Study subjects (N = 3696) were adolescents aged 13- and 15-years from the schools in Lithuania who were surveyed in Spring 2014 according to the methodology of the cross-national Health Behaviour in School-aged Children (HBSC). A standard HBSC international questionnaire was translated into Lithuanian and used anonymously to obtain information about current smoking patterns and family life (family structure, quality of communication in family, parental monitoring, bonding, parenting style, family time, etc.). Logistic regression was used to assess association between smoking and familial variables. The prevalence of current smoking was 16.5 % (20.8 % in boys and 11.9 % in girls; P satisfaction with family relationships (OR = 1.89; 95 % CI: 1.27-2.83), low school-related parental support (OR = 1.40; 95 % CI: 1.01-1.95), easy communication with the father (OR = 0.56; 95 % CI: 0.38-0.80) and often use of electronic media for communication with parents (OR = 0.66; 95 % CI: 0.50-0.88). The last two determinants showed an inverse effect than it was hypothesized. Higher prevalence of smoking among adolescents of Lithuania is associated with a non- intact family structure as well as weaker parental support and bonding. Family life practices are critical components to be incorporated in prevention and intervention programs for adolescent smoking in Lithuania.

    A questionnaire was performed in order to determine smoking prevalence in the target population just before the initiation of a social responsibility project which is aimed to increase the smoking cessation rates in Kocaeli. The sample selection was made based on population numbers in 12 town of Kocaeli city and smoking habits of population over the age of 18 were evaluated by a questionnaire survey by phone. There was 2721 person included in the study. The overall prevalence of active smokers was 32.3% (n= 902) and ex-smokers was 21.5% (n= 587). There was no statistical significance of smoking prevalence among towns except the lower smoking rates in Gebze (25.7%). The percentage of the current smokers was 42.5% in male population which was significantly higher than females (21.8%). The highest smoking prevalence was found between the ages of 35-44 (41.2%) while the lowest prevalence was observed in the subjects older than 55 years (19.8%). The mean age for smoking initiation was 19 years (17-20) and daily cigarette consumption was 17 sticks. Previous attempts for quitting smoking were found in 67.7% of current smokers. The mean number of smoking cessation attempts was 3 times and the mean duration of cessation was 5 months. The most common reason for smoking cessation was health issues. Eighty percent of cases harnessed their willpower to stop smoking while only 5% of them received medical treatment. It is suggested that determination of demographic features of the smokers might constitute a corner stone for smoking cessation projects.

  10. REVIEW ON CURRENT WORLDWIDE STATUS, DISTRIBUTION, ECOLOGY AND DIETARY HABITS OF GOLDEN JACKAL, CANIS AUREUS

    2014-12-01

    Full Text Available The golden jackal is a medium-sized predator and omnivore, with a range covering the southern parts of the Palearctic, South Asia and northeastern Africa. The entire jackal population is now confined to a few clusters grouped into 7 sub-areas with criteria such as connectivity and isolation. Causes of decline seem to be related to the limited habitat availability due to changes in human agro-pastoral activities, which resulted mainly in reduced day-cover availability and possibly reduced food base. This review summarizes the basic aspects of golden jackal distribution, ecology and dietary habits, analyses the main threats and problems of jackal management. The jackals seem to do well in moderately modified agro-systems with non- invasive human activities. Barriers for jackal expansion and population recovery seems to be the mountains with extensive high forests or unbroken scrub, heavy snowy winters and irregular food supply, large intensively cultivated areas without cover, urbanization and established wolf populations. Agro pastoral changes during the past 25-30 years has resulted in habitat and human use changes, which have largely contributed to the massive jackal population declines. Following a short introduction on phylogeny, classification, and evolutionary ecology of the Canidae, this review provides the latest information on the distribution, biology and conservation status of Canid aureus species, organized by geographical region.

Even after cessation of alcohol consumption, many recovering alcoholics continue to smoke. In this exploratory study, we examined how current smoking and a history of alcoholism interacted in relation to brain volumes and neuropsychological performance. Methods: Participants were 14 abstinent long-term alcoholics (seven current smokers and seven nonsmokers, and 13 nonalcoholics (six current smokers and seven nonsmokers. The groups were equivalent in age, gender, education, and intelligence quotient. Two multiecho magnetization-prepared rapid acquisition with gradient echo (MP-RAGE scans were collected for all participants using a 3T magnetic resonance imaging scanner with a 32 channel head coil. Brain volumes for each gray and white matter region of interest were derived using FreeSurfer.

    Introduction Concurrent use of cigarettes and smokeless tobacco is common, but little is known regarding the association of smokeless tobacco use with cigarette smoking cessation. Dual users may have lower cigarette consumption levels, which may also play a role in smoking cessation. Methods The 2010–2011 Tobacco Use Supplement to the Current Population Survey included 26,760 current cigarette smokers, of which 675 concurrently used smokeless tobacco. We compared characteristics of the most recent cigarette smoking quit attempt of the past year between dual users and exclusive smokers, using multivariate regression. Results Dual users (45%) were more likely than exclusive smokers (37%) to have made a cigarette smoking quit attempt during the previous year (pcigarette dependence levels (ORadj 1.33, 95% CI 1.15–1.53). Half (48%) of dual users who made a quit attempt tried to quit “by switching to smokeless tobacco”. However, once in a quit attempt, dual users relapsed more quickly than exclusive smokers (Cox regression HRadj 1.13, 95% CI 1.02–1.26). There was no difference in 30-day abstinence rates on the most recent quit attempt (ORadj 1.09, 95% CI 0.88–1.37). For both groups, the best predictor of past 30-day abstinence was cigarette consumption level. Conclusions Current cigarette smokers who also use smokeless tobacco are more likely to have tried to quit, but relapse more quickly than exclusive smokers, and are not more likely to have attained 30 day smoking cessation. Prospective studies at the population level are needed. PMID:26253939

    CYP2E1 is a versatile phase I drug-metabolizing enzyme responsible for the biotransformation of most volatile organic compounds, including toluene. Human toluene exposure increases CYP2E1 mRNA and modifies its activity in leucocytes; however, epigenetic implications of this interaction have not been investigated. To determine promoter methylation of CYP2E1 and other genes known to be affected by toluene exposure. We obtained venous blood from 24 tannery workers exposed to toluene (mean levels: 10.86+/-7mg/m(3)) and 24 administrative workers (reference group, mean levels 0.21+/-0.02mg/m(3)) all of them from the city of León, Guanajuato, México. After DNA extraction and bisulfite treatment, we performed PCR-pyrosequencing in order to measure methylation levels at promoter region of 13 genes. In exposed group we found significant correlations between toluene airborne levels and CYP2E1 promoter methylation (r=-.36, ptoluene-exposed smokers compared to nonsmokers (p=0.009). We also observed significant correlations for CYP2E1 promoter methylation with GSTP1 and SOD1 promoter methylation levels (r=-.37, ptoluene exposure. People co-exposed to toluene and tobacco smoke are in higher risk due to a possible CYP2E1 repression. Copyright © 2015 Elsevier Inc. All rights reserved.

    Cigarette smoking is a modifiable risk factor for cognitive impairment, while the relationship between current smoking and cognitive impairment is not fully understood. The objectives were to identify a possible association between current smoking and cognitive impairment depending on age in the Chinese rural population. Data for the study consisted of 1,782 participants (40 years and older) who lived in a rural village in the vicinity of Xi'an, China. Data about smoking history and cognitive function were collected. Cognitive function was scored by the Mini-Mental State Examination. The effect of age on the relationship between current smoking and cognitive impairment was analyzed with interaction and stratified analysis by logistic regression models. Interaction analysis showed that current smoking is positively related with cognitive impairment (odds ratio [OR]=9.067; 95% confidence interval [95% CI] 1.305-62.979; P=.026). However, the interaction term, age by current smoking, is negatively related with cognitive impairment (OR=0.969; 95%CI 0.939-0.999; P=.045). Stratified logistic regression showed that in the 40-65 years of age sublayer, OR of current smoking is 1.966 (P=.044), whereas in the>65 years of age sublayer, the OR is 0.470 (P=.130). This means that the association between current smoking and cognitive impairment with age might be positive (OR>1) in lower age sublayers, but no significant difference in higher age sublayers. In conclusion, current smoking might be positively associated with cognitive impairment in the middle-aged but the relationship declines with increasing age. Copyright © 2017 Elsevier España, S.L.U.

    Full Text Available Abstract Background There are very few clinical reports that have compared the association between cigarette smoking and microangiopathy in Asian patients with type 1 diabetes mellitus (T1DM. The objective of this study was to assess the relationships between urinary protein concentrations and smoking and gender-based risk factors among patients with T1DM. Methods A cross-sectional study of 259 patients with T1DM (men/women = 90/169; mean age, 50.7 years who visited our hospital for more than 1 year between October 2010 and April 2011 was conducted. Participants completed a questionnaire about their smoking habits. Patient characteristics included gender, age, body mass index, blood pressure, hemoglobin A1c, lipid parameters, and microangiopathy. Diabetic nephropathy (DN was categorized as normoalbuminuria (NA, microalbuminuria (MA, or overt albuminuria (OA on the basis of the following urinary albumin/creatinine ratio (ACR levels: NA, ACR levels less than 30 mg/g creatinine (Cr; MA, ACR levels between 30 and 299 mg/g Cr; and OA, ACR levels over 300 mg/g Cr. Results The percentages of current nonsmokers and current smokers with T1DM were 73.0% (n = 189 and 27.0% (n = 70, respectively. In addition, the percentage of males was higher than that of females (52.2% versus 13.6% in the current smoking population. The percentage of DN was 61.8% (n = 160 in patients with NA, 21.6% (n = 56 in patients with MA, and 16.6% (n = 43 in patients with OA. The percentage of males among OA patients was also higher than that of females (24.4% versus 12.4%. However, current smoking status was associated with OA in females with T1DM only [unadjusted odds ratio (OR, 4.13; 95% confidence interval (CI, 1.45–11.73, P P  Conclusions Based on our results in this cross-sectional study of Asian patients with T1DM, smoking might be a risk factor for OA among female patients. Further research is needed of these gender-specific results.

    The aims of the present study were to investigate the current exposure levels of persistent organochlorine compounds (OCs) in adipose tissues intraoperatively collected from 40 patients over 20 years undergoing non-cancer-related surgery residing in Northern region of Tunisia (Bizerte), which constitutes an exemplary case, and examined association between levels of contamination and both socio-demographic characteristics and dietary habits. Concentration of hexachlorobenzene (HCB), hexachlorocyclohexane isomers (α-HCH, β-HCH, γ-HCH and δ-HCH), dichlorodiphenyltrichloroethane isomers (p,p'-DDT and o,p'-DDT) and metabolites (p,p'-DDE, o,p'-DDE, p,p'-DDD and o,p'-DDD) and 12 polychlorinated biphenyls (PCBs) congeners were measured using capillary gas chromatography with electron capture detector. Overall, residue levels of OCs followed the decreasing order of DDTs > PCBs > HCB > HCHs. DDTs levels ranged from 74.49 to 1834.76ngg(-1) lipid and contributing to more than 90% to the sum of organochlorine pesticides (OCPs). p,p'-DDE was the most abundant in all samples and the p,p'-DDT/p,p'-DDE ratio (range between 1.85% and 58.45%) suggesting recent and ongoing exposure to banned commercial DDT products. PCB concentrations varied from 29.27 to 322.58ngg(-1) lipid and PCB-180, PCB-153 and PCB-138 were the dominant congeners accounting for 70% of total PCBs. We did not find significant correlations between OC exposure levels and sex, parity, habitat areas and smoking habits. In females, the adipose tissue concentrations of DDTs, HCB and PCB-118 were positively correlated with age. There was statistically significant relationship between body mass index (BMI) changes and the adipose tissue levels of HCB and HCHs. No association was found between OCPs levels and dietary factors. However, our study suggests that fish consumption may be an important contributor of PCBs adipose tissue content of PCBs in Tunisian people. The presented work is highly significant, being the

Human toluene exposure increases CYP2E1 mRNA and modifies its activity in leucocytes; however, epigenetic implications of this interaction have not been investigated. Goal: To determine promoter methylation of CYP2E1 and other genes known to be affected by toluene exposure. Methods: We obtained venous blood from 24 tannery workers exposed to toluene (mean levels: 10.86 +/− 7 mg/m{sup 3}) and 24 administrative workers (reference group, mean levels 0.21 +/− 0.02 mg/m{sup 3}) all of them from the city of León, Guanajuato, México. After DNA extraction and bisulfite treatment, we performed PCR-pyrosequencing in order to measure methylation levels at promoter region of 13 genes. Results: In exposed group we found significant correlations between toluene airborne levels and CYP2E1 promoter methylation (r = − .36, p < 0.05), as well as for IL6 promoter methylation levels (r = .44, p < 0.05). Moreover, CYP2E1 promoter methylation levels where higher in toluene-exposed smokers compared to nonsmokers (p = 0.009). We also observed significant correlations for CYP2E1 promoter methylation with GSTP1 and SOD1 promoter methylation levels (r = − .37, p < 0.05 and r = − .34, p < 0.05 respectively). Conclusion: These results highlight the importance of considering CYP2E1 epigenetic modifications, as well as its interactions with other genes, as key factors for unraveling the sub cellular mechanisms of toxicity exerted by oxidative stress, which can initiate disease process in chronic, low-level toluene exposure. People co-exposed to toluene and tobacco smoke are in higher risk due to a possible CYP2E1 repression. - Highlights: • We investigated gene-specific methylation in persons chronically exposed to toluene. • In a previous study, a reduced CYP2E1 activity was observed in these participants. • CYP2E1

    To assess the association between current active and passive tobacco smoking and living with a same-sex partner in Spain. We analysed data from two cross-sectional national surveys of the Spanish population 15 years and older (2011-Encuesta Nacional de Salud en España and 2014-Encuesta Europea de Salud en España). Analyses included only people living with their partner. Associations were calculated using multiple logistic regressions adjusting for gender, social class and age. Current active and passive smoking were significantly associated with living with same sex partners (odds ratio: 2.71 and 2.88), and particularly strong among women. Spanish adults living with same-sex partners are at higher risk of active and passive smoking. This risk varies by gender. Spanish national surveys should include items on sexual orientation for improved data on health disparities. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

    The purpose of this study was to conduct a preliminary assessment of province of residence and other contextual factors on the likelihood of being a current smoker in China. A cross-sectional, multistage sampling process was used to recruit participants, and their smoking status and sociodemographic characteristics were obtained through face-to-face interviews. The contextual variables were retrieved from a national database. Multilevel logistic regression analysis was performed to assess the impact of provincial economic reliance on the tobacco industry, as well as individual-level characteristics, on the likelihood of being a current smoker. Participants totaled 20,601 from 27 cities located in 26 of the 31 municipalities/provinces in China. Overall smoking prevalence was 31.3% (95% CI: 19.3-33.2%), with rates being highest in Yinchuan City in Ningxia Province (49.8%) and lowest in Shanghai (21.6%). The multilevel analysis showed an excess likelihood of being a current smoker for individuals living in provinces with the highest rate of cigarette production relative to those with the smallest (pmarketing of tobacco products in China.

    E-cigarette use among adolescents has increased significantly in recent years, but it remains unclear whether cigarette smoking behaviors and intentions for future cigarette smoking differ among current (i.e., 30-day) non-users, only e-cigarette users, only cigarette smokers, and dual users. A nationally representative sample of 4385 U.S. high school seniors were surveyed during the spring of their senior year via self-administered questionnaires in 2014. An estimated 9.6% of U.S. high school seniors reported current e-cigarette use only, 6.3% reported current cigarette smoking only, and 7.2% reported current dual use of e-cigarettes and cigarette smoking. There were no significant differences between current only cigarette smokers and dual users in the odds of early onset of cigarette smoking, daily cigarette smoking, intentions for future cigarette smoking, friends' cigarette smoking behaviors, attempts to quit cigarette smoking, or the inability to quit cigarette smoking. Adolescents who only used e-cigarettes had higher odds of intentions for future cigarette smoking in the next 5years (AOR=2.57, 95% CI: 1.21-5.24) than current non-users. Dual users and only cigarette smokers had higher odds of cigarette smoking behaviors and intentions for future cigarette smoking than non-users or only e-cigarette users. Adolescents who engage in current dual use have cigarette smoking behaviors and intentions for future cigarette smoking that more closely resemble cigarette smokers than e-cigarette users. Adolescents who only use e-cigarettes have higher intentions to engage in future cigarette smoking relative to their peers who do not engage in e-cigarette use or cigarette smoking.

    Smoking is one of the varied psychological reactions to stress. This study examined the rate and changes in cigarette smoking among former Gaza and current West Bank Jewish settlers subjected to direct and indirect terrorist attacks during the Al-Aksa Intifada. The relationship with degree of religious observance and emotional distress was explored as well. In this cross-sectional study, the respondents were settlers randomly selected and interviewed by telephone (N = 706). The interview schedule included socio-demographic items, information on direct exposure to terrorist attacks (e.g. threat to life or physical integrity, personal losses, property damage) and on steady and changes in smoking habits, and a scale to measure emotional distress. In contrast with the country population, a larger percentage of settlers who smoked increased the number of cigarettes consumed with exposure to terrorism (10 and 27%, respectively). Respondents who were injured or had their home damaged reported a higher rate of smoking during the preceding year (30 and 20%, respectively). Emotional distress was related to cigarette smoking, but not in the controlled analysis. Religious observance had no effect. Direct or indirect exposure to terrorist attacks had an impact on smoking prevalence rates and on changes in smoking habits. Studies investigating reactions to traumatic events should include a detailed section on smoking while mental health interventions should address the needs of smokers.

    Full Text Available Las enfermeras de Atención Primaria (AP son profesionales adecuados en la lucha contra el tabaquismo. No obstante, algunas de ellas fuman y esto puede disminuir su credibilidad y su sentimiento de autoeficacia frente al problema. El objetivo de este estudio es evidenciar los factores que pueden influir en el inicio y el mantenimiento del hábito tabáquico. Para ello, se ha realizado un estudio cualitativo desde una perspectiva fenomenológica social, en 15 enfermeras fumadoras de AP, recogiendo los datos mediante entrevista semiestructurada en profundidad. Los principales temas que emergieron fueron la falta de concienciación y el papel socializador del tabaco. Se tiene poca conciencia del papel de la publicidad y no se considera al estrés como un determinante del hábito en el ámbito de AP. Puede resultar decisivo el control del peso corporal.Primary Health Care Nurses (PHC are suitable professionals in the fight against the smoking habit. Nevertheless some of them smoke and this may diminish their credibility and their feeling of self-efficacy when faced with this problem. The aim of this study was to demonstrate the factors that may influence taking up and maintaining the smoking habit. Thus, we carried out a qualitative study from a social phenomenological perspective, in 15 PHC nurses who are smokers, collecting the data by means of a semi-structured in-depth interview. The main issues that emerged were lack of awareness and the socializing role of tobacco. There is little awareness of the role of publicity and stress is not considered to be a determining factor of the habit in the area of PHC. The control of body weight may be decisive.

    The number of smokers in Chinese rural areas is more than 200 million, which is twice that in cities. It is very significant to carry out tobacco control interventions in rural areas. We performed this community intervention study to evaluate the efficacy of village-based health education of tobacco control on the male current smoking rate in rural areas. The population of this study was the males above 15 years old from 6 villages in rural areas. The villages were randomly assigned to intervention group or control group (3 villages in each group). Self-designed smoking questionnaire was applied. The intervention group received the village-based health education of tobacco control for one year. The primary outcome measurement was the male current smoking rate. In the baseline investigation, completed surveys were returned by 814 male residents from the control group and 831 male residents from the intervention group. The male current smoking rate in the control group and the intervention group was 61.2% and 58.5%, respectively, before intervention. There was no significant difference between these two groups (P>0.05). After one-year intervention, the current smoking rate in the intervention group (51.2%) was significantly lower than that in the control group (62.8%) (Pareas, which could be a suitable and feasible way for tobacco control in the Chinese rural areas.

    Background Poor lifestyle, including suboptimal diet, physical inactivity, and tobacco use are leading causes of preventable diseases globally. Although even modest population shifts in risk substantially alter health outcomes, the optimal population-level approaches to improve lifestyle are not well established. Methods and Results For this American Heart Association Scientific Statement, the writing group systematically reviewed and graded the current scientific evidence for effective population approaches to improve dietary habits, increase physical activity, and reduce tobacco use. Strategies were considered in 6 broad domains: (1) media and education campaigns; (2) labeling and consumer information; (3) taxation, subsidies, and other economic incentives; (4) school and workplace approaches; (5) local environmental changes; and (6) direct restrictions and mandates. The writing group also reviewed the potential contributions of healthcare systems and surveillance systems to behavior change efforts. Several specific population interventions that achieved a Class I or IIa recommendation with grade A or B evidence were identified, providing a set of specific evidence-based strategies that deserve close attention and prioritization for wider implementation. Effective interventions included specific approaches in all 6 domains evaluated for improving diet, increasing activity, and reducing tobacco use. The writing group also identified several specific interventions in each of these domains for which current evidence was less robust, as well as other inconsistencies and evidence gaps, informing the need for further rigorous and interdisciplinary approaches to evaluate population programs and policies. Conclusions This systematic review identified and graded the evidence for a range of population-based strategies to promote lifestyle change. The findings provide a framework for policy makers, advocacy groups, researchers, clinicians, communities, and other

    Full Text Available Introduction: Smoking approval by friends and teachers seems to increase the probability of smoking by the students. This study aimed to determine whether adolescent smoking is associated with teachers or other students smoking, after controlling for confounders. Methods: A sample of the 3rd grade students of Tehran's high schools were asked to complete a 21 item questionnaire, including demographic and smoking habits. The comparisons of adolescent smoking pattern between two sexes and also smoking frequency of the family members, best friends and teachers between the smoking and non-smoking students, were performed. Furthermore, the association between smoking behavior and exposure to teachers smoking were assessed by a multivariate logistic regression analysis, adjusted for sex, parental, best friends, and sibling smoking. Odds Ratios were estimated. Results: Among the 4591 students (aged 17-19, mean 17.53±0.59 years, including 2092 boys (45.6% and girls, 250 boys (12.1% and 131 girls (5.3% were current smokers (p=0.001. The proportion of smoker and non-smoker students who have been exposed to teachers smoking inside the school building were 55.7% (209 and 29.3% (1191 respectively (p=0.001. The 220 (58.7% exposed students to outdoors teachers smoking (on school premises were smoker while 1205 (29.2% were non-smoker (p=0.001. By adjustment of the parameters, adolescent exposure to best friend smoking and to teachers smoking on school premises was significantly associated with current smoking. Conclusion: Teachers smoking during school hours and best friend smoking are the two important determinants to be considered in any project aiming to establish tobacco-free schools.

    2005-06-01

    The present research investigated the mechanisms guiding habitual behavior, specifically, the stimulus cues that trigger habit performance. When usual contexts for performance change, habits cannot be cued by recurring stimuli, and performance should be disrupted. Thus, the exercising, newspaper reading, and TV watching habits of students transferring to a new university were found to survive the transfer only when aspects of the performance context did not change (e.g., participants continued to read the paper with others). In some cases, the disruption in habits also placed behavior under intentional control so that participants acted on their current intentions. Changes in circumstances also affected the favorability of intentions, but changes in intentions alone could not explain the disruption of habits. Furthermore, regardless of whether contexts changed, nonhabitual behavior was guided by intentions.

  13. Protobacco Media Exposure and Youth Susceptibility to Smoking Cigarettes, Cigarette Experimentation, and Current Tobacco Use among US Youth.

    Full Text Available Youth are exposed to many types of protobacco influences, including smoking in movies, which has been shown to cause initiation. This study investigates associations between different channels of protobacco media and susceptibility to smoking cigarettes, cigarette experimentation, and current tobacco use among US middle and high school students.By using data from the 2012 National Youth Tobacco Survey, structural equation modeling was performed in 2013. The analyses examined exposure to tobacco use in different channels of protobacco media on smoking susceptibility, experimentation, and current tobacco use, accounting for perceived peer tobacco use.In 2012, 27.9% of respondents were never-smokers who reported being susceptible to trying cigarette smoking. Cigarette experimentation increased from 6.3% in 6th grade to 37.1% in 12th grade. Likewise, current tobacco use increased from 5.2% in 6th grade to 33.2% in 12th grade. Structural equation modeling supported a model in which current tobacco use is associated with exposure to static advertising through perception of peer use, and by exposure to tobacco use depicted on TV and in movies, both directly and through perception of peer use. Exposure to static advertising appears to directly increase smoking susceptibility but indirectly (through increased perceptions of peer use to increase cigarette experimentation. Models that explicitly incorporate peer use as a mediator can better discern the direct and indirect effects of exposure to static advertising on youth tobacco use initiation.These findings underscore the importance of reducing youth exposure to smoking in TV, movies, and static advertising.

    Full Text Available Background: Cigarettes smoking is a common mode of consuming tobacco in India. This habit usually starts in adolescence and tracks across the life course. Interventions like building decision making skills and resisting negative influences are effective in reducing the initiation and level of tobacco use. Aims and Objectives: The purpose of this study was to assess the prevalence of adolescent current cigarette smoking behavior and to investigate the individual and social factors, which influence them both to and not to smoke. Methodology: A cross-sectional study was carried out among school going adolescents in Shimla town of North India. After obtaining their written informed consent, a questionnaire was administered. Results: The overall prevalence of current cigarette smoking was 11.8%. The binary logistic regression model revealed that parents′ and peers′ smoking behavior influence adolescent smoking behavior. Individual self-harm tendency also significantly predicted cigarette smoking behavior. Parental active participation in keeping a track of their children′s free time activities predicted to protect adolescents from taking this habit. Conclusion: Our research lends support to the need for intervention on restricting adolescents from taking up this habit and becoming another tobacco industries′ addicted customer. Parents who smoke should quit this habit, which will not only restore their own health, but also protect their children. All parents should be counseled to carefully observe their children′s free time activities.

    ex-smokers in order to draw a profile of their smoking habits. Results: Women accounted for 80% of the 430 nurses surveyed and their average age was 38. Of all nurses, 26.7% were smokers, 20.5% were ex-smokers and 52.8% were non-smokers. Smokers ask their patients fewer questions about their smoking habits, consider themselves less well-informed about how to address the issue and advise their patients to quit smoking on fewer occasions than non-smoking nurses do. Primary care professionals smoke less than specialised nurses do. Conclusion: Further training in smoking issues needs to be conducted, as half the nurses do not feel properly prepared to handle smoking issues.

Moreover, factors associated with current smoking in COPD patients and differences by sex have not been fully elucidated. Data from the 2011 and 2012 Behavioral Risk Factor Surveillance System was used in this study. Four HRQOL indicators were examined in this study: general health, physical health, mental health, and activity limitations. General health was dichotomized into two groups: “excellent/very good/good” and “fair/poor”, and the other three HRQOL indicators were dichotomized into <14 (infrequent and ≥14 (frequent unhealthy days in the past 30 days. To examine HRQOL indicators in association with current versus former smoking and identify factors associated with current smoking, logistic regression models were used. Sex differences were explored. In COPD patients, current smokers compared to former smokers had significantly poor HRQOL on all subdomains: “fair/poor” general health (adjusted odds ratio [AOR]: 1.2 [95% confidence interval {CI}: 1.1–1.5]; poor physical health (AOR: 1.3 [CI: 1.1–1.5]; poor mental health (AOR: 1.8 [CI: 1.4–2.2]; and poor activity limitations (AOR: 1.5 [CI: 1.3–1.9].

    Full Text Available Abstract Background In the last decade Poland has successfully carried out effective anti-tobacco campaigns and introduced tobacco control legislation. This comprehensive strategy has focused on the general population and has led to a considerable decrease in tobacco consumption. Prisoners constitute a relatively small part of the entire Polish population and smoking habits in this group have been given little attention. The aim of the study was to assess the prevalence of cigarette smoking in Polish male prisoners, factors determining smoking in this group, prisoners' attitudes towards smoking cessation, and to evaluate prisoners' perception of different anti-tobacco measures. Methods An anonymous questionnaire including personal, demographic and smoking data was distributed among 944 male inmates. Of these, 907 men aged between 17 and 62 years (mean 32.3 years met the inclusion criteria of the study. For the comparison of proportions, a chi-square test was used with continuity correction whenever appropriate. Results In the entire group, 81% of the subjects were smokers, 12% – ex-smokers, and 7% – never smokers. Current smokers had significantly lower education level than non-smokers (p Conclusion The prevalence of cigarette smoking among Polish prisoners is high. However, a majority of smokers attempt to quit, and they should be encouraged and supported. Efforts to reduce cigarette smoking in prisons need to take into consideration the specific factors influencing smoking habits in prisons.

    First Nations and Métis, two of Canada's constitutionally recognized Indigenous groups, suffer from poorer overall health than non-Indigenous Canadians. Current smoking, a known predictor of chronic health conditions, is close to twice as prevalent among Indigenous youth as it is among non-Indigenous Canadian youth. However, little population-level research has examined the correlates of current smoking among this population. Guided by a health framework centered on Indigenous-specific determinants, we used data from the 2012 Aboriginal Peoples Survey to examine the correlates of current smoking among First Nations and Métis youth aged 15-17 years living outside of First Nations reserves. Using binary logistic regression, we investigated how culturally specific factors, namely knowledge of an Indigenous language, participation in traditional activities, and family members' attendance at residential schools, were correlated with current smoking. We also considered demographic, geographic, socioeconomic and health-related correlates. Overall, an estimated 20.6% of First Nations and Métis youth reported current smoking. We found no significant associations between culturally specific activities and current smoking in the multivariate analyses, although those who spoke an Indigenous language were more likely to smoke. Those who participated in sports more often were less likely to smoke, and respondents who reported heavy drinking and who were from families with lower income were more likely to smoke. Gender, body mass index, urban/rural geography and regional geography, and mother's highest level of education were not significantly correlated with smoking. The results of our study support prior research that has found a disturbingly high prevalence of current smoking among Indigenous youth, compared to their non-Indigenous counterparts. Our results highlight the importance of considering sports participation, co-occurring health-risk behaviours and socioeconomic

    Full Text Available Objective: tobacco smoking is the most commonly substance abused in psychiatric patients; among them, patients with schizophrenia are the highest abusers. Smoking is related to a decrease in the quality life and life expectancy, as well as interacting with psychotropic drugs. In Mexico, there is not basic descriptive knowledge about the main variables related to cigarette smoking in psychiatric population. The aim of this study was to know the relation among variables (beginning and course of the disease, use of other drugs and times of hospitalization among others and cigarette smoking in a Mexican population of hospitalized schizophrenic patients. Method: The relation between the main variables and smoking were evaluated in a Mexican population of schizophrenic patients while hospitalized. A casuistic sampling was performed in 96 patients diagnosed with schizophrenia and they were divided into three groups: 1 non-smokers, 2 ex-smokers and 3 smokers; according to their score on the Fagerström Test for Nicotine Dependence. Results: The results showed that hospitalized schizophrenic patients smoke 2.7 times more than the general population. Most of these patients showed moderate to high dependence of nicotine, as well as a higher risk for other drugs abuse (marihuana mainly. Most patients started smoking before the first positive symptoms of schizophrenia appeared, and their symptoms started at an earlier age than in patients without a smoking background. Conclusions: Similar studies will allow deepening into specific aspects that modify and or improve the prescribed treatments for each psychiatric patient in hospital settings.

    We conducted a survey to elucidate the influence with menopause symptoms and the impact of not only smoking but also using make-up among for Japanese women, included ages above and below the menopausal generation. The subjects of this study were 335 Japanese women from 35 to 59 years of age who were examined for the first time in the specialized women's outpatient clinic of our institution from July 2010 to June 2011 for 1 year period. We used the items of the Menopause-Specific Quality of Life Questionnaire. Similarly, we analysed the scores in relation to menopausal symptoms and whether the subject smoked, whether the subject used make-up depend on women (including foundation, lip rouge, brush one's eyebrows), how frequently she used make-up. The JMP version 9.0 software program was used to statistically analyse the score data. Significant associations were observed in psychosocial (P = 0.0196), tended to be more severe in women before menopause and after climacteric. Furthermore, the frequency of using make-up were negative relations with menopause symptoms (P = 0.0251) after climacteric. Smoking had made worse for physical symptoms (P psychological symptoms. Also, physical conditions were influenced by smoking. Using make-up frequently was often seen after climacteric because of appearance changes by oestrogen dynamic decline.

    Full Text Available Habitable Trinity is a newly proposed concept of a habitable environment. This concept indicates that the coexistence of an atmosphere (consisting largely of C and N, an ocean (H and O, and a landmass (supplier of nutrients accompanying continuous material circulation between these three components driven by the Sun is one of the minimum requirements for life to emerge and evolve. The life body consists of C, O, H, N and other various nutrients, and therefore, the presence of water, only, is not a sufficient condition. Habitable Trinity environment must be maintained to supply necessary components for life body. Our Habitable Trinity concept can also be applied to other planets and moons such as Mars, Europa, Titan, and even exoplanets as a useful index in the quest for life-containing planetary bodies.

This concept indicates that the coexistence of an atmosphere (consisting largely of C and N), an ocean (H and O), and a landmass (supplier of nutrients) accompanying continuous material circulation between these three components driven by the Sun is one of the minimum requirements for life to emerge and evolve. The life body consists of C, O, H, N and other various nutrients, and therefore, the presence of water, only, is not a sufficient condition. Habitable Trinity environment must be maintained to supply necessary components for life body. Our Habitable Trinity concept can also be applied to other planets and moons such as Mars, Europa, Titan, and even exoplanets as a useful index in the quest for life-containing planetary bodies.

    Full Text Available Abstract Introduction Tobacco cigarette smoking a well-known cause of cancer and other diseases. Hookah smoking is another form of tobacco use that has rapidly spread in the United State and Europe. This study assessed beliefs about the harmfulness of smoking hookah. Methods We surveyed hookah users in all cafes that provided hookah to its customers in downtown San Diego, California and nearby areas. A total of 235 hookah users participated in this study. Results Average age of study participants was 22 years, 57% were males, and 72% were not cigarette smokers. Whites were more likely to use hookah than the other ethnic groups (33%, older hookah users (26-35 years were mostly males, and mint flavor of hookah tobacco was the most popular among a wide variety of flavors (23%. There was no significant difference in gender in relation to the wrong perception that hookah is less harmful than cigarettes, but those of Asian ethnicity were much less likely than other ethnic groups to believe that hookah is less harmful than cigarettes. More frequent users of hookah were more likely to believe that hookah is less harmful than cigarettes. The majority of hookah users (58.3% believe hookah is less harmful than cigarette smoking. Discussion Compared to cigarettes, there appears to be a lack of knowledge about the harmfulness of smoking hookah among users regardless of their demographic background. Education about the harmfulness of smoking hookah and policies to limit its use should be implemented to prevent the spread of this new form of tobacco use.

    At the 1st Medical Faculty of Charles University in Prague the prevalence of smoking was investigated among the faculty, staff, students and among health professionals in the country. We found 38.1% smokers (current and occasional) among malephysicians (N = 625), 25.6% smokers among women physicians (N = 394), 48.7% smoking nurses (N = 729) and 42.3% smokers among paramedical staff (N = 298). We have also followed up smoking habits among our students since 1989 (N = 1235). The number of smokers among them rose from 7% in 1989 to 18% in 1994. Students were also asked about their opinion on smoking as a risk factor for coronary heart disease which has a rising trend. Trying to coordinate the anti-smoking activity at all seven medical faculties in the Czech Republic, in collaboration with the Faculty of Medicine of Masaryk University in Brno, the National Centre for Health Promotion and the Czech Commission of EMASH, present the main points of the anti-smoking strategy at Czech medical faculties.

    The effects of occupational exposure to low concentrations of polychlorobiphenyls (PCBs) on the urinary excretion of corticosteroid hormones were evaluated, taking into account the influence of cigarette smoking. The study included 26 males working as electrical maintenance staff in a steel factory, previously exposed to a mixture of PCBs (exposed workers), and 30 male workers with no occupational exposure to PCBs (controls). Serum PCBs (33 congeners), urinary 17-hydroxycorticosteroids, 17-ketosteroids (KS) and pregnanes, and their respective glucuronidated and sulfonated compounds, were determined for each subject. PCBs were significantly higher in the exposed workers than controls, and were correlated with age. Both the urinary concentrations of the total 17-KS and pregnanes, and those of some single steroids and their glucuronidated compounds, were significantly lower in the exposed workers than controls, but higher in smokers than the non-smokers + ex-smokers. Two-way analysis of variance showed a negative association between serum PCBs and both total glucuronidated 17-KS and total and glucuronidated pregnanes, and a positive association between cigarette smoking and both total and glucuronidated 17-KS. PCBs seem to act as endocrine disruptors by reducing the urinary excretion of corticosteroid hormones, particularly of the glucuronidated fraction. Cigarette smoking could boost these effects of PCBs in smokers.

    Schizophrenia is characterized by cognitive deficits which persist after acute symptoms have been treated or resolved. Transcranial direct current stimulation (tDCS) has been reported to improve cognition and reduce smoking craving in healthy subjects but has not been as carefully evaluated in a randomized controlled study for these effects in schizophrenia. We conducted a randomized double-blind, sham-controlled study of the effects of 5 sessions of tDCS (2 milliamps for 20minutes) on cognition, psychiatric symptoms, and smoking and cigarette craving in 37 outpatients with schizophrenia or schizoaffective disorder who were current smokers. Thirty subjects provided evaluable data on the MATRICS Consensus Cognitive Battery (MCCB), with the primary outcome measure, the MCCB Composite score. Active compared to sham tDCS subjects showed significant improvements after the fifth tDCS session in MCCB Composite score (p=0.008) and on the MCCB Working Memory (p=0.002) and Attention-Vigilance (p=0.027) domain scores, with large effect sizes. MCCB Composite and Working Memory domain scores remained significant at Benjamini-Hochberg corrected significance levels (α=0.05). There were no statistically significant effects on secondary outcome measures of psychiatric symptoms (PANSS scores), hallucinations, cigarette craving, or cigarettes smoked. The positive effects of tDCS on cognitive performance suggest a potential efficacious treatment for cognitive deficits in partially recovered chronic schizophrenia outpatients that should be further investigated.

    Full Text Available Jennifer ZJ Maccani, Matthew A Maccani Penn State Tobacco Center of Regulatory Science, College of Medicine, Department of Public Health Sciences, Hershey, PA, USA Abstract: The developmental origins of health and disease hypothesis states that adverse early life exposures can have lasting, detrimental effects on lifelong health. Exposure to maternal cigarette smoking during pregnancy is associated with morbidity and mortality in offspring, including increased risks for miscarriage, stillbirth, low birth weight, preterm birth, asthma, obesity, altered neurobehavior, and other conditions. Maternal cigarette smoking during pregnancy interferes with placental growth and functioning, and it has been proposed that this may occur through the disruption of normal and necessary placental epigenetic patterns. Epigenome-wide association studies have identified a number of differentially methylated placental genes that are associated with maternal smoking during pregnancy, including RUNX3, PURA, GTF2H2, GCA, GPR135, and HKR1. The placental methylation status of RUNX3 and NR3C1 has also been linked to adverse infant outcomes, including preterm birth and low birth weight, respectively. Candidate gene analyses have also found maternal smoking-associated placental methylation differences in the NR3C1, CYP1A1, HTR2A, and HSD11B2 genes, as well as in the repetitive elements LINE-1 and AluYb8. The differential methylation patterns of several genes have been confirmed to also exhibit altered gene expression patterns, including CYP1A1, CYP19A1, NR3C1, and HTR2A. Placental methylation patterns associated with maternal smoking during pregnancy may be largely gene-specific and tissue-specific and, to a lesser degree, involve global changes. It is important for future research to investigate the mechanistic roles that these differentially methylated genes may play in mediating the association between maternal smoking during pregnancy and disease in later life, as well

    We have little knowledge about the evolution of emphysema, and relatively little is understood about its evolution in relation to smoking habits. This study aims to assess the evolution of emphysema in asymptomatic current and former smokers over 2 years and to investigate the association with subjects' characteristics. The study was approved by our Ethics Committee and all participants provided written informed consent. We measured emphysema by automatic low-dose computed tomography densitometry in 254 current and 282 former smokers enrolled in a lung-cancer screening. The measures were repeated after 2 years. The association between subjects' characteristics, smoking habits and emphysema were assessed by chi-squared and Wilcoxon tests. Univariate and multivariate odds ratios (OR) with 95% confidence intervals (CI) were calculated for the risk of emphysema worsening according to subjects' characteristics. We assessed the trend of increasing risk of emphysema progression by smoking habits using the Mantel-Haenszel chi-squared test. The median percentage increase in emphysema over a 2-year period was significantly higher in current than in former smokers (OR 1.8; 95% CI 1.3-2.6; p < 0.0001). The risk of worsening emphysema (by 30% in 2 years) in current smokers increased with smoking duration (p for trend <0.02). As emphysema is a known risk factor for lung cancer, its evaluation could be used as a potential factor for identification of a high-risk population. The evaluation of emphysema progression can be added to low-dose CT screening programmes to inform and incite participants to stop smoking. (orig.)

    2012-02-01

    An increasing number of initiatives to regulate cigarette smoke constituents beyond 'tar', nicotine and carbon monoxide are being launched. The objective of existing and proposed regulation is presumably either to gain a better understanding of product performance, to be able to discriminate between products, or to impose limits for selected constituents. However, without standardized analytical methods and measurement tolerances a meaningful comparison of data or verification against regulated limits is challenging if not impossible. Hence, an understanding of the validity and limitations of generated data is important for industry and regulators alike to avoid unjustified 'out-of-compliance' situations, and consequent competitive and reputational concerns for manufacturers. This paper reviews smoke constituent regulation and provides examples of technical challenges and good practice. It discusses approaches used to standardize measurements; the role of the International Organization for Standardization; factors influencing result variability and limitations and possible misinterpretations of generated data. If smoke constituents regulation is to be introduced, a standardized, science-based approach must be the pre-requisite for the generation and comparison of data. Potential analytical and technical issues must be resolved in discussion, both before and after the implementation of regulation, to the benefit of the public, regulators and manufacturers.

    Full Text Available Abstract An evaluation of the cellular alterations in the smoker's oral mucosal cells was performed. Exfoliative Citology technique were applied and the cytologic smears stained with silver for quantitative analyses of Argyrophilic nucleolar organizer regions. (AgNORs. Cytologic smears were collected from two anatomic sites, mouth floor and tongue border with the purpose of relating the frequency of smoking with the quantitative analyses of the AgNORs. This study showed that the average number of AgNORs/nucleus is related with the number of cigarettes per day in the mouth floor of smoker's. These results suggest a possible relation between the number of cigarettes per day and an increase rate of cellular proliferation in the oral mucosal cells.

    Four factors which influence smoking treatment outcome are identified: environmental variables, client characteristics, process variables, and specific treatment approaches. Important environmental factors are stress and social support. Of client characteristics, sex is the best predictor of treatment success. Men are more likely to quit and maintain abstinence than women. However, the majority of women alter their smoking habits during pregnancy. Low-income persons and ethnic minorities are underrepresented among subjects in treatment studies and have larger percentages of smokers in the population at large. Extraverted smokers are more likely to begin to smoke and have difficulty quitting. Also, the more anxious, poorly adjusted smoker has more trouble quitting than the less troubled smoker. The higher the client's sense of self-efficacy, the better the chance of that person entering treatment and doing well. Furthermore, smokers who take in lower levels of nicotine are more successful at quitting. Many process questions are suggested. Few have been approached empirically. The effectiveness of ex-smokers as therapists in smoking cessation programs has not been systematically investigated, even though the smoking history of therapists is a question frequently asked by clients. We suggest that the skill and empathy of group leaders is more important than smoking history. Smoking therapists should be aware of nonspecific treatment factors such as positive expectations, social reinforcement, and self-disclosure which may have a powerful influence on the efficacy of smoking treatment. Specific treatment approaches were classified into three categories: low-contact approaches, including educational, self-help, and minimal treatment approaches; psychological treatments; and pharmacological treatment. Education, self-help, and minimal treatment approaches are thought to be accretively effective when the large size of the audience is considered. Also, innovative

Materials and Methods: Cross-sectional survey in which anonymous, self-administered questionnaire was used to survey the cigarette smoking habits of the first- and second-year medical students in the Faculty of Medicine, King Fahad Medical City in June 2009. Results: Overall 39.8 % of the investigated students (153 had smoked before, and 17.6% were current smokers. The mean age of initiating smoking was 15.8 (΁3.3. There were significantly more males than females. The most important reasons for smoking were leisure, imitation of other people and a means of relieving psychological pressure. Reasons for not smoking were mostly health and religion-based. Smokers tended to have friends who smoked. Conclusion: Cigarettes smoking is highly prevalent among medical students in the Faculty of Medicine, King Fahad Medical City. Contact with smokers particularly friends are the major risk factors for the initiation of the habit. Health and religious considerations are important motives for not smoking, quitting or attempting to quit. These findings can be of help in designing future intervention strategies.

    Full Text Available Recent investigations show that the smoking prevalence among asthmatic adolescents is higher than among healthy adolescents, and the causes that lead these asthmatic adolescents to smoke are unclear. We investigated the association between family structure, parental smoking, smoking friends, and smoking in asthmatic adolescents (n = 6,487. After adjusting for sex and age, logistic regression analyses showed that nonintact family structure, parental smoking, and smoking friends are associated with smoking in adolescents with and without asthma. Asthmatic adolescents who reside in the household of a nonintact family have a 1.90 times greater risk of smoking compared with those who live with both biological parents. It is important that parents who have children with asthma be made aware that the presence of smokers in the home and adolescent fraternization with smoking friends not only favor the worsening of asthma, but also induce the habit of smoking.

    The electrical characteristics of a steady-state negative DC corona discharge in a two-phase fluid (air with suspended cigarette smoke particles) flowing along a chamber with a needle-to-plate electrode arrangement were experimentally investigated. The two-phase flow was transverse in respect to the needle-to-plate axis. The velocity of the transverse two-phase flow was limited to 0.8 m/s, typical of the electrostatic precipitators. We found that three discharge current modes of the negative corona exist in the two-phase (air + smoke particles) fluid: the Trichel pulses mode, the "Trichel pulses superimposed on DC component" mode and the DC component mode, similarly as in the corona discharge in air (a single-phase fluid). The shape of Trichel pulses in the air + suspended particles fluid is similar to that in air. However, the Trichel pulse amplitudes are higher than those in "pure" air while their repetition frequency is lower. As a net consequence of that the averaged corona discharge current in the two-phase fluid is lower than in "pure" air. It was also found that the average discharge current decreases with increasing suspended particle concentration. The calculations showed that the dependence of the average negative corona current (which is a macroscopic corona discharge parameter) on the particle concentration can be explained by the particle-concentration dependencies of the electric charge of Trichel pulse and the repetition frequency of Trichel pulses, both giving a microscopic insight into the electrical phenomena in the negative corona discharge. Our investigations showed also that the average corona discharge current in the two-phase fluid is almost unaffected by the transverse fluid flow up to a velocity of 0.8 m/s.

    There are no large-scale, carefully designed cohort studies that provide evidence on whether menthol cigarette use is associated with a differential risk of initiating and/or progressing to increased smoking. However, questions of whether current menthol cigarette smokers initiated smoking at a younger age or are more likely to have transitioned from non-daily to daily cigarette use compared to non-menthol smokers can be addressed using cross-sectional data from U.S. government surveys. Analyses of nationally representative samples of adult and youth smokers indicate that current menthol cigarette use is not associated with an earlier age of having initiated smoking or greater likelihood of being a daily versus non-daily smoker. Some surveys likewise provide information on cigarette type preference (menthol versus non-menthol) among youth at different stages or trajectories of smoking, based on number of days smoked during the past month and/or cigarettes smoked per day. Prevalence of menthol cigarette use does not appear to differ among new, less experienced youth smokers compared to established youth smokers. While there are limitations with regard to inferences that can be drawn from cross-sectional analyses, these data do not suggest any adverse effects for menthol cigarettes on measures of initiation and progression to increased smoking.

    Full Text Available Sickle cell disease (SCD is an autosomal recessive hemoglobinopathy that causes significant morbidity and mortality related to chronic hemolytic anemia, vaso-occlusion, and resultant end-organ damage. Tobacco smoke exposure (TSE through secondhand smoke exposure in people with SCD of all ages and through primary smoking in adolescents and adults is associated with significantly increased morbidity, with increased rates of emergency department visits and hospitalizations for painful vaso-occlusive crises and acute chest syndrome (ACS. Secondhand smoke is also associated with pulmonary function abnormalities in children with SCD who are already at risk for pulmonary function abnormalities on the basis of SCD. TSE is emerging as one of the few modifiable risk factors of SCD. This review discusses the current state of the evidence with respect to TSE and SCD morbidity, discusses potential mechanisms, and highlights current gaps in the evidence and future research directions.

    Significant evidence outlines that the management of the high-risk surgical patient with perioperative hemodynamic optimization leads to significant benefits. This study aimed at studying the current practice of hemodynamic monitoring and management of Italian anesthesiologists. An invitation to participate in a web-based survey was published on the web site of the Società Italiana di Anestesia Analgesia Rianimazione Terapia Intensiva. Overall, 478 questionnaires were completed. The most frequently used monitoring techniques was invasive blood pressure (94.1 %). Cardiac output was used in 41.3% of the cases mainly throughout less-invasive methods. When cardiac output was not monitored, the main reason given was that other surrogate techniques, mainly central venous oxygen saturation (40.5%). Written protocols concerning hemodynamic management in high-risk surgical patients were used by the 29.1% of the respondents. 6.3% of the respondents reported not to be aware if such document was available at their institution. 86.3% of the respondents reported that they usually optimize high risk patients but to use blood flow assessment rarely (39.7%). The most used parameter in clinical practice to assess the effects of volume loading were an increase in urine output and arterial blood pressure together with a decrease in heart rate and blood lactates. The 45.1% or the respondents outlined that hemodynamic optimization in the high risk patients is of major clinical value. Our study outlines an important gap between available evidence and clinical practice emphasizing the need for a better awareness, more information and knowledge on the specific topic.

    The search for exoplanets includes the promise to eventually find and identify habitable worlds. The thousands of known exoplanets and planet candidates are extremely diverse in terms of their masses or sizes, orbits, and host star type. The diversity extends to new kinds of planets, which are very common yet have no solar system counterparts. Even with the requirement that a planet's surface temperature must be compatible with liquid water (because all life on Earth requires liquid water), a new emerging view is that planets very different from Earth may have the right conditions for life. The broadened possibilities will increase the future chances of discovering an inhabited world.

    Aldehyde dehydrogenase 2 (ALDH2) detoxifies toxic aldehydes, e.g. acetaldehyde in cigarette smoke; however, the interactive effects between smoking status and the ALDH2 genotype on coronary artery disease (CAD) have not been reported. We investigated the effects of smoking status and the ALDH2 genotype, and assessed their interactive and combined effects on the risk of myocardial infarction (MI) or stable angina (SA), including 221 MI and 175 SA subjects and 473 age- and sex-matched controls without CAD. Current-smoking and the ALDH2*2 allele additively increased the risk of MI (adjusted odds ratio 4.54, 95% confidence interval 2.25-9.15), although this combination was not associated with the risk of SA. This combination also increased the peak creatine kinase (CK) level synergistically in the acute MI (AMI) subjects. Moreover, current-smoking was found to be a significant risk factor for an increased peak CK level in the ALDH2*2 allele carriers (B 2220.2IU/L, p=0.008), but not the non-carriers. Additionally, a synergistic effect of this combination on the triglycerides levels was also found in the AMI subjects. These preliminary findings suggest that the combination of current-smoking and the inactive ALDH2*2 allele may increase the risk of MI additively and the infarct size synergistically.

    Full Text Available Objectives: This study was conducted to examine the prevalence of smoking and habits of smoking among male secondary school students in Jeddah, Kingdom of Saudi Arabia (KSA and to assess their knowledge and attitudes toward it. Materials and Methods: A cross-sectional study was conducted in Jeddah, using a two-stage cluster sampling, randomly selecting 4 out of 85 government male secondary schools. Data were obtained through a self-administered questionnaire eliciting responses to questions on personal background, smoking behavior, knowledge, behavior, and attitude toward smoking. A total of 695 students responded to the questionnaires with 87.4% response rate. Results: Of the studied group, 258 (37% currently smoked, and of these, 83.7% had started smoking at the age of 14 years or less. The most common reason for smoking was the influence of family, especially the presence of someone at home who smoked (65, 9% and friends who smoked (42.5%. Many of the students search for information on the risks of smoking (66.3%, and only (45.3% knew about the bad effects of passive smoking on others. Two-third of the students who smoked wanted to quit smoking (63.2%, especially if suitable help was offered, whereas (60.9% had tried to quit. While 50% of students smoked for recreation and entertainment, and (33.6% had difficulty avoiding smoking in no smoking areas. Conclusion: A well-planned integrated antismoking campaign is urgently required, especially among students and teachers. The study revealed that the prevalence of smoking was high. This will contribute to an increase in smoking-related health problems in the future if proper preventive measures are not taken.

    An unintended consequence of tobacco control's success in marginalizing smoking is that smokers may conceal their smoking from those who are best positioned to help them quit: health care providers (HCPs). The purpose of this study was to identify the prevalence of, and factors related to, nondisclosure of smoking to HCPs. Data were obtained from…

    Full Text Available Background. Detoxification programmes seek to implement the most secure and compassionate ways of withdrawing from opiates so that the inevitable withdrawal symptoms and other complications are minimized. Once detoxification has been achieved, the next stage is to enable the patient to overcome his or her drug addiction by ensuring consumption is permanently and completely abandoned, only after which can the subject be regarded as fully recovered. Methods. A systematic search on the common databases of relevant papers published until 2016 inclusive. Results and Conclusion. Our study of the available oral treatments for opioid dependence has revealed that no current treatment can actually claim to be fully effective. These treatments require daily oral administration and, consequently, regular visits to dispensaries, which in most cases results in a lack of patient compliance, which causes fluctuations in drug plasma levels. We then reviewed alternative treatments in the available scientific literature on polymeric sustained release formulations. Research has been done not only on release systems for detoxification but also on release systems for giving up the habit of taking opioids. These efforts have obtained the recent authorization of polymeric systems for use in patients that could help them to reduce their craving for drugs.

    Epidemiological surveys tried to measure the respective role of air pollution and smoking on the respiratory diseases. In the sixties, air pollution was the major cause and the smoking habits were not included in the surveys. Nowaday the decreasing air pollution and the increasing smoking habits highlight the new etiology of BPCO, fibrosis and lund cancers.

    Full Text Available Objective. Previous studies have indicated that cigarette smokers are more likely to develop type 2 diabetes and that both smoking and type 2 diabetes are associated with C-reactive protein (CRP. This study examined whether CRP mediates the association between smoking quantity and type 2 diabetes. Methods. Nine hundred and eighty-four current Chinese smokers were selected from a community-based chronic disease survey conducted in Guangzhou and Zhuhai. Type 2 diabetes was defined according to the WHO 1999 criteria. CRP was measured with flow cytometry. Binary logistic regression was performed to assess the mediation. Results. A positive association was observed between smoking quantity and type 2 diabetes (P<0.05. After controlling for potential confounders, daily cigarette consumption was significantly associated with higher CRP levels. Current smokers with type 2 diabetes had higher CRP levels than smokers without type 2 diabetes. The association between the smoking quantity and type 2 diabetes was mediated by CRP, which accounted for 50.77% of the association. Conclusions. This study provides further evidence that smoking quantity is positively associated with type 2 diabetes and suggests that the association between smoking and type 2 diabetes might be mediated by CRP.

    Background Research suggests that ACEs have a long-term impact on the behavioral, emotional, and cognitive development of children. These disruptions can lead to adoption of unhealthy coping behaviors throughout the lifespan. The present study sought to examine psychological distress as a potential mediator of sex-specific associations between adverse childhood experiences (ACEs) and adult smoking. Method Data from 7,210 Kaiser-Permanente members in San Diego California collected between April and October 1997 were used. Results Among women, psychological distress mediated a significant portion of the association between ACEs and smoking (21% for emotional abuse, 16% for physical abuse, 15% for physical neglect, 10% for parental separation or divorce). Among men, the associations between ACEs and smoking were not significant. Conclusions These findings suggest that for women, current smoking cessation strategies may benefit from understanding the potential role of childhood trauma. PMID:22788356

    Cigarette smoking and the use of smokeless tobacco both cause substantial morbidity and premature mortality. The concurrent use of these products might increase dependence and the risk for tobacco-related disease and death. State-specific estimates of prevalence and relative percent change in current cigarette smoking, smokeless tobacco use, and concurrent cigarette smoking and smokeless tobacco use among U.S. adults during 2011-2013, developed using data from the Behavioral Risk Factor Surveillance System (BRFSS), indicate statistically significant (pcigarette smoking prevalence overall and in 26 states. During the same period, use of smokeless tobacco significantly increased in four states: Louisiana, Montana, South Carolina, and West Virginia; significant declines were observed in two states: Ohio and Tennessee. In addition, the use of smokeless tobacco among cigarette smokers (concurrent use) significantly increased in five states (Delaware, Idaho, Nevada, New Mexico, and West Virginia). Although annual decreases in overall cigarette smoking among adults in the United States have occurred in recent years, there is much variability in prevalence of cigarette smoking, smokeless tobacco, and concurrent use across states. In 2013, the prevalence ranged from 10.3% (Utah) to 27.3% (West Virginia) for cigarette smoking; 1.5% (District of Columbia and Massachusetts) to 9.4% (West Virginia) for smokeless tobacco; and 3.1% (Vermont) to 13.5% (Idaho) for concurrent use. These findings highlight the importance of sustained comprehensive state tobacco-control programs funded at CDC-recommended levels, which can accelerate progress toward reducing tobacco-related disease and deaths by promoting evidence-based population-level interventions. These interventions include increasing the price of tobacco products, implementing comprehensive smoke-free laws, restricting tobacco advertising and promotion, controlling access to tobacco products, and promoting cessation assistance

    We examined the relationship between two forms of ethnic discrimination-interpersonal and institutional-and smoking outcomes among Arab men in Israel, and whether social support buffered these associations. We used cross-sectional data of adult Arab men, current or former smokers (n = 954). Mixed-effects regression models estimated the association between discrimination and smoking status, and nicotine dependence among current smokers. Interpersonal discrimination was associated with higher likelihood of being a current smoker compared to a former smoker, whereas institutional group discrimination was not. Social support moderated the ethnic discrimination-nicotine dependence link. Among men with low social support, greater interpersonal discrimination was associated with greater nicotine dependence. Similarly, among smokers with high institutional group discrimination, those with high social support reported lower nicotine dependence compared to those with low social support. Ethnic discrimination should be considered in efforts to improve smoking outcomes among Arab male smokers in Israel.

    Full Text Available Abstract Background Tobacco smoking issues in developing countries are usually taught non-systematically as and when the topic arose. The World Health Organisation and Global Health Professional Student Survey (GHPSS have suggested introducing a separate integrated tobacco module into medical school curricula. Our aim was to assess medical students' tobacco smoking habits, their practices towards patients' smoking habits and attitude towards teaching about smoking in medical schools. Methods A cross-sectional questionnaire survey was carried out among final year undergraduate medical students in Malaysia, India, Nepal, Pakistan, and Bangladesh. An anonymous, self-administered questionnaire included items on demographic information, students' current practices about patients' tobacco smoking habits, their perception towards tobacco education in medical schools on a five point Likert scale. Questions about tobacco smoking habits were adapted from GHPSS questionnaire. An 'ever smoker' was defined as one who had smoked during lifetime, even if had tried a few puffs once or twice. 'Current smoker' was defined as those who had smoked tobacco product on one or more days in the preceding month of the survey. Descriptive statistics were calculated. Results Overall response rate was 81.6% (922/1130. Median age was 22 years while 50.7% were males and 48.2% were females. The overall prevalence of 'ever smokers' and 'current smokers' was 31.7% and 13.1% respectively. A majority (> 80% of students asked the patients about their smoking habits during clinical postings/clerkships. Only a third of them did counselling, and assessed the patients' willingness to quit. Majority of the students agreed about doctors' role in tobacco control as being role models, competence in smoking cessation methods, counseling, and the need for training about tobacco cessation in medical schools. About 50% agreed that current curriculum teaches about tobacco smoking but not

    Prevention and cessation of Tobacco use among persons living with HIV/AIDS (PLWHA) represents a significant challenge for HIV/AIDS patient care in China and across the globe. Awareness of HIV-positive status may alter the likelihood for PLWHA smokers to change their smoking habit. In this study, we tested the risk enhancement and risk reduction hypotheses by assessing changes in cigarette smoking behavior among PLWHA after they received the positive results of their HIV tests. Cross-sectional survey data collected from a random sample of 2973 PLWHA in care in Guangxi, China were analyzed. Changes in cigarette smoking after receiving the HIV-positive test results, as well as the current levels of cigarette smoking were measured. Among the total participants, 1529 (51.7%) were self-identified as cigarette smokers, of whom 436 (28.9%) reduced smoking and 286 (19.0%) quit after receiving their HIV-positive test results. Among the quitters, 210 (73.9%) remained abstinent for a median duration of two years. There were also 124 (8.2%) who increased cigarette smoking. Older age, female gender, more education, and receiving antiretroviral therapy were associated with quitting. In conclusion, our study findings support the risk reduction and risk enhancement hypotheses. A large proportion of smoking PLWHA reduced or quit smoking, while a small proportion increased smoking. Findings of this study suggest that the timing when a person receives his or her HIV-positive test result may be an ideal opportunity for care providers to deliver tobacco cessation interventions. Longitudinal studies are indicated to verify the findings of this study and to support smoking cessation intervention among PLWHA in the future.

    Some waterpipe smokers exhibit nicotine dependent behaviors such as increased use over time and inability to quit, placing them at high risk of adverse health outcomes. This study examines the determinants of dependence by measuring frequency of use among current waterpipe smokers using a large national U.S. Data were drawn from four waves (Spring/Fall 2009 and Spring/Fall 2010) of the American College Health Association-National College Health Assessment datasets. The sample was restricted to students who smoked a waterpipe at least once in the past 30 days (N=19,323). Ordered logistic regression modeled the factors associated with higher frequency of waterpipe smoking. Among current waterpipe smokers, 6% used a waterpipe daily or almost daily (20-29 days). Daily cigarette smokers were at higher odds of smoking a waterpipe at higher frequencies compared with non-smokers of cigarettes (OR=1.81; 95% CI=1.61-2.04). There was a strong association between daily cigar smoking and higher frequency of waterpipe smoking (OR=7.77; 95% CI=5.49-11.02). Similarly, students who used marijuana had higher odds of smoking a waterpipe at higher frequencies (OR=1.57; 95% CI=1.37-1.81). Daily consumers of other addictive substances are at a higher risk of intensive waterpipe smoking and thus higher risk of waterpipe dependence. Intervention programs must incorporate methods to reduce waterpipe dependence and subsequently prevent its deleterious health effects. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    OBJECTIVE To explore the current status of smoking and Second-Hand smoking exposure in work places in Nanchang City, provide evidence for policy-making, and to promote enacting ' Non-smoking workplace' legislation. METHODS Field observation, questionnaire survey and the TSI Side Pak was used to measure indoor air PM2.5 level in workplaces. RESULTS Field observation was conducted among 29 work places, of which 2 were smoke-free places regulated by the ordinance, 16 had established smoking areas and No-smoking areas; In the smoke-free places, the percentage of smoking phenomenon ratio in (10, 50) was 50%. Among the survey workers, the general passive smoking rate was 51.9%; 60.7% of smokers smoked in the no-smoking areas, and the percentage of worker's discourage rate was only 5.9%. The average indoor air PM2.5 level was 49.7 μg/m3 in work places with complete smoke free policies, 67.6μg/m3 in work places with partial smoke free policies, 66.0μg/m3 in work places with no rules or restrictions on smoking. CONCLUSION The smoking phenomenon in the work places in Nanchang City was seriously, and the rate of Second-Hand smoking exposure to high. Anti-smoking measures was imperfect, and the charged with smoke was not sufficient. Need to enhance smoker's awareness of the harm of smoking and Second-Hand smoking, and enter corresponding "Non-smoking workplace" local code and legislation.%目的 了解南昌市办公场所吸烟和二手烟暴露情况,为政府决策提供依据,促进“无烟工作场所”立法.方法 采用现场观察,问卷拦截调查和对工作场所空气中PM2.5浓度进行监测等方法,分析南昌市办公场所吸烟和二手烟暴露情况.结果 现场观察了29家办公场所,禁烟场所2家,16家场所划分了吸烟区和非吸烟区;全面禁烟场所吸烟现象比例在(10,50]的分布为50%.被调查工作人员中,有51.9%在工作单位受到二手烟的侵害;有60.7%的吸烟者在工作场所的非吸烟区内吸

    In a multigenerational study of smoking risk, the objective was to investigate the intergenerational transmission of smoking by examining if exposure to parental smoking and nicotine dependence predicts prospective smoking trajectories among adolescent offspring. Adolescents (n = 406) ages 12 to 17 and a parent completed baseline interviews (2001-2004), and adolescents completed up to 2 follow-up interviews 1 and 5 years later. Baseline interviews gathered detailed information on parental smoking history, including timing and duration, current smoking, and nicotine dependence. Adolescent smoking and nicotine dependence were assessed at each time point. Latent Class Growth Analysis identified prospective smoking trajectory classes from adolescence into young adulthood. Logistic regression was used to examine relationships between parental smoking and adolescent smoking trajectories. Four adolescent smoking trajectory classes were identified: early regular smokers (6%), early experimenters (23%), late experimenters (41%), and nonsmokers (30%). Adolescents with parents who were nicotine-dependent smokers at baseline were more likely to be early regular smokers (odds ratio 1.18, 95% confidence interval 1.05-1.33) and early experimenters (odds ratio 1.04, 95% confidence interval 1.04-1.25) with each additional year of previous exposure to parental smoking. Parents' current non-nicotine-dependent and former smoking were not associated with adolescent smoking trajectories. Exposure to parental nicotine dependence is a critical factor influencing intergenerational transmission of smoking. Adolescents with nicotine-dependent parents are susceptible to more intense smoking patterns and this risk increases with longer duration of exposure. Research is needed to optimize interventions to help nicotine-dependent parents quit smoking early in their children's lifetime to reduce these risks.

Sociodemographic factors and details about smoking habits and RAS in last 12 months were collected.Results: Annual prevalence (AP of RAS was 37.1%. Tobacco use was common among students: 30.2% were current smokers and 2.8% were exsmokers. AP was not significantly influenced by students’ age, gender, marital status, college, and household income but was significantly affected by place of living (P = 0.02 and presence of chronic diseases (P = 0.03. No significant difference in AP of RAS was found between smokers and nonsmokers. Cigarette smokers who smoked heavily and for a longer period of time had significantly less AP of RAS when compared to moderate smokers and those who smoked for a shorter period of time. The protective effect of smoking was only noticed when there was heavy cigarette smoking (>20 cigarettes/day (P = 0.021 or smoking for long periods of time (>5 years (P = 0.009. Nevertheless, no significant associations were found between intensity or duration of smoking and clinical severity of RAS lesions.Conclusion: The “protective effect” of smoking on RAS was dose- and time-dependent. When lesions are present, smoking had no effect on RAS severity.Keywords: recurrent aphthous stomatitis, smoking, prevalence

    This study evaluated among hospital nurses the smoking status, knowledge and attitudes regarding smoking cessation services, and smoking behaviour 3years after the implementation of smoke-free workplace law (decree no. 2006-1386). A descriptive study was undertaken in a public referral hospital in the South of France. Between February and April 2010, a questionnaire was distributed to the nurses. Data on demographic information, smoking status, behaviour and attitudes regarding smoking addiction, and knowledge regarding smoking cessation services were collected. Changes in nurses' smoking habits were studied through a former study conducted in this hospital a year after the law had come into effect. Three years after the enactment of the smoking ban, 30% (30% in 2008) reported themselves as current smokers, 26% (25% in 2008) as ex-smokers and 44% (45% in 2008) as non-smokers. Among smokers, 72% (68% in 2008) declared they had decreased tobacco consumption during working hours and 50% (29% in 2008) daily cigarette consumption. The majority of nurses (88%) supported the smoke-free law. A higher percentage of smokers than non smokers have knowledge of smoking cessation services. The smoking prevalence among hospital nurses seemed to have remained constant between 2008 and 2010 despite a better compliance with the law. France's national smoke-free workplace law is associated with a reduction in tobacco consumption and exposure to second-hand smoke in nurses but not smoking prevalence. The other measures of the MPOWER package have to be reinforced. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Aims We evaluated coronary artery disease (CAD) extent, severity, and major adverse cardiac events (MACEs) in never, past, and current smokers undergoing coronary CT angiography (CCTA). Methods and results We evaluated 9456 patients (57.1 ± 12.3 years, 55.5% male) without known CAD (1588 current smokers; 2183 past smokers who quit ≥3 months before CCTA; and 5685 never smokers). By risk-adjusted Cox proportional-hazards models, we related smoking status to MACE (all-cause death or non-fatal myocardial infarction). We further performed 1:1:1 propensity matching for 1000 in each group evaluate event risk among individuals with similar age, gender, CAD risk factors, and symptom presentation. During a mean follow-up of 2.8 ± 1.9 years, 297 MACE occurred. Compared with never smokers, current and past smokers had greater atherosclerotic burden including extent of plaque defined as segments with any plaque (2.1 ± 2.8 vs. 2.6 ± 3.2 vs. 3.1 ± 3.3, P < 0.0001) and prevalence of obstructive CAD [1-vessel disease (VD): 10.6% vs. 14.9% vs. 15.2%, P < 0.001; 2-VD: 4.4% vs. 6.1% vs. 6.2%, P = 0.001; 3-VD: 3.1% vs. 5.2% vs. 4.3%, P < 0.001]. Compared with never smokers, current smokers experienced higher MACE risk [hazard ratio (HR) 1.9, 95% confidence interval (CI) 1.4–2.6, P < 0.001], while past smokers did not (HR 1.2, 95% CI 0.8–1.6, P = 0.35). Among matched individuals, current smokers had higher MACE risk (HR 2.6, 95% CI 1.6–4.2, P < 0.001), while past smokers did not (HR 1.3, 95% CI 0.7–2.4, P = 0.39). Similar findings were observed for risk of all-cause death. Conclusion Among patients without known CAD undergoing CCTA, current and past smokers had increased burden of atherosclerosis compared with never smokers; however, risk of MACE was heightened only in current smokers.

    Full Text Available BACKGROUND: As smoking is a major risk factor in India, the objective of present study was to assess smoking patterns, expenditure and awareness amongst smokers and to examine factors associated with the severity of smoking in Surat city.METHODS: Community-based cross-sectional study was conducted with the use of pre-structured questionnaire tool targeting 281 current smokers in the slums of 20 Urban Health Centers. Smokers were categorized based on pack-years, which means the number of packs smoked per day multiplied by the duration of smoking (mild 15, and based on the number of cigarette/bidis smoked per day without the duration component (mild 0.05. With the influence of friends (50%, about 60% smokers engage into this habit before the age of 20 years. Though only 20% of current smokers were not aware of the consequences of active smoking, more than 50% did not know about the same for passive smoking. The lowest socioeconomic class spends 44% of their income on tobacco products compared to 7% in the highest class.CONCLUSION: The study provides insights for information, education and counseling (IEC activities which should take into account health impact of bidi smoking, low awareness of health impact of passive smoking, and higher percentage of total monthly expenditure on tobacco among low-income household resulting in crowding out of expenditures on other needs.

    Full Text Available Tobacco dependence has currently become a health issue. Although it resembles other addictions in many aspects, it meets some specific features that hinder awareness and eradication by the very smoker. Motivating the patient to act in favor of a change in his lifestyle is essential in any medical intervention. In this paper we clarify motivational strategies for a more effective intervention based on knowledge of how people change their behavioral patterns according to their expectations, whether they are sufficiently encouraged and if the professional has the necessary therapeutic tools in the context of health care.La dependencia tabáquica es sin dudas un problema de salud en la actualidad y aunque se asemeja en muchos aspectos al resto de las adicciones, reúne algunas características específicas que dificultan la toma de conciencia y su erradicación por parte del fumador. Motivar al paciente para que actúe a favor de un cambio en su estilo de vida es esencial en cualquier intervención médica. En este trabajo se esclarecen estrategias motivacionales para hacer más efectiva esa intervención a partir del conocimiento de cómo las personas modifican sus patrones comportamentales en función de sus expectativas, si estas son suficientemente incentivadas y el profesional cuenta con las herramientas terapéuticas necesarias en el marco del proceso de atención médica.

    There is some evidence to suggest that young women dieters who smoke experience greater cigarette cravings in the presence of food-related related cues. The aim of this experiment was to examine reactivity to both smoking-related and water cues by dieting and non-dieting women smokers in the presence or absence of food cues. Eighteen female undergraduates attended two sessions (food present and food absent). At each session, participants were presented with a cigarette and water cue in a counterbalanced order. Pre- and post-cue measures included the brief version of the Questionnaire for Smoking Urges, heart rate and self-reported mood. All smokers showed enhanced reactivity (increased craving and heart rate) to smoking versus water cues. For dieters there was a larger increase in cigarette craving and heart rate in response to the smoking-related cues in the presence of food compared with the absence of food, whereas for non-dieters there was a smaller increase in cigarette craving and heart rate in response to the smoking-related cues in the presence of food compared with the absence of food. Mood and appetite ratings were not significantly affected by either cue type or session. The results suggest that cue reactivity to smoking-related cues is modulated by the presence of incentive stimuli relevant to the individual.

    Full Text Available Goblet cell hyperplasia is a classic but variable pathologic finding in COPD. Current literature shows that smoking is a risk factor for chronic bronchitis but the relationship of these clinical features to the presence and magnitude of large airway goblet cell hyperplasia has not been well described. We hypothesized that current smokers and chronic bronchitics would have more goblet cells than nonsmokers or those without chronic bronchitis (CB, independent of airflow obstruction.We recruited 15 subjects with moderate to severe COPD, 12 healthy smokers, and 11 healthy nonsmokers. Six endobronchial mucosal biopsies per subject were obtained by bronchoscopy and stained with periodic acid Schiff-Alcian Blue. Goblet cell density (GCD was quantified as goblet cell number per millimeter of basement membrane. Mucin volume density (MVD was quantified as volume of mucin per unit area of basement membrane.Healthy smokers had a greater GCD and MVD than nonsmokers and COPD subjects. COPD subjects had a greater GCD than nonsmokers. When current smokers (healthy smokers and COPD current smokers, n = 19 were compared with all nonsmokers (nonsmoking controls and COPD ex-smokers, n = 19, current smokers had a greater GCD and MVD. When those with CB (n = 12 were compared to those without CB (n = 26, the CB group had greater GCD. This finding was also seen in those with CB in the COPD group alone. In multivariate analysis, current smoking and CB were significant predictors of GCD using demographics, lung function, and smoking pack years as covariates. All other covariates were not significant predictors of GCD or MVD.Current smoking is associated with a more goblet cell hyperplasia and number, and CB is associated with more goblet cells, independent of the presence of airflow obstruction. This provides clinical and pathologic correlation for smokers with and without COPD.

  19. Cosmological aspects of planetary habitability

    2014-01-01

    The habitable zone (HZ) is defined as the region around a star where a planet can support liquid water on its surface, which, together with an oxygen atmosphere, is presumed to be necessary (and sufficient) to develop and sustain life on the planet. Currently, about twenty potentially habitable planets are listed. The most intriguing question driving all these studies is whether planets within habitable zones host extraterrestrial life. It is implicitly assumed that a planet in the habitable zone bears biota. However along with the two usual indicators of habitability, an oxygen atmosphere and liquid water on the surface, an additional one -- the age --- has to be taken into account when the question of the existence of life (or even a simple biota) on a planet is addressed. The importance of planetary age for the existence of life as we know it follows from the fact that the primary process, the photosynthesis, is endothermic with an activation energy higher than temperatures in habitable zones. Therefore on...

    This study was conducted to examine the prevalence of smoking and the smoking habits among male secondary school students in Jeddah, Kingdom of Saudi Arabia and to assess their knowledge and attitudes towards smoking. A cross-sectional study was conducted in Jeddah, using a two-stage cluster sample that randomly selected four schools from 85 public secondary schools for males. Data were obtained through a self-administered questionnaire containing questions on personal background, smoking behavior, knowledge, and behavior and attitudes towards smoking. A total of 695 students responded to the questionnaires with an 87.4% response rate. The age range of this student sample was 16-22 years. Two hundred fifty-eight (37%) of the study group were current smokers. The most common reasons given for smoking were personal choice (50.8%) and the peer pressure from smoker friends (32.8%). Many students researched the smoking hazards (68.1%), but only 47.6% knew about the bad effects of passive smoking. Two thirds of the smoking students wanted to quit smoking (63.2%), especially if suitable help was available, and 75.1% tried to quit. A third of the smoking students (36.8%) found it difficult to stop smoking in no-smoking areas. A well-planned integrated antismoking campaign is urgently required, especially among students and teachers. Our study revealed that smoking prevalence was high, which will lead to future high smoking-related health problems if proper preventive measures are not taken accordingly.

    There is a dearth of information about the smoking habits of people currently and formerly treated for tuberculosis (TB) in low- and middle-income countries (LMICs). In this paper we describe research carried out in Indonesia between 2007 and 2011 designed to investigate both the impact of TB-specific quit smoking messages in the TB clinic and at home, and shifts in patterns of smoking among those formerly treated for TB who continue to smoke. The results of a modest two-arm smoking cessation trial involving 87 patients undergoing Directly Observed Therapy Short course treatment (DOTS) for TB are presented. In one arm patients received a TB-specific quit smoking message delivered by doctors and a TB and smoking educational booklet and quit smoking guide. In the second, family support arm, patients also received on-going cessation messages delivered by family members trained to be DOTS supporters. The study followed patients twice during their six months of DOTS treatment and twice six months post treatment. Both arms of the study reduced rates of smoking during and following TB treatment significantly with 73% of patients in the doctor arm and 71% in the family support arm remaining quit at the end of the treatment (month 6). When complete abstinence at six months after treatment was taken as a primary outcome measure, no statistical difference was found in the effectiveness of the two arms of the intervention. Notably, 67% of higher-level smokers at baseline and 33% of low-moderate level smokers at baseline quit entirely. Many of those who resumed smoking did so at low-moderate levels (smoking at a low-moderate level (smoking at a higher level. A purposeful sample of 15 patients who shifted from heavy smoking (20-40 cigarettes per day) to low-moderate levels of smoking post treatment were followed for an additional 12 months. We report on their ability to sustain lower levels of smoking and self-perceived smoking status given their dramatic reduction in cigarette

    The habit of smoking was well-known in Norway in the first half of the sixteenth century. Tobacco-smoking is seen in Norwegian paintings. In the nineteenth century, long and artistic pipes were used by men relaxing after a pleasant dinner. In self portraits of Christian Krohg and Edvard Munch we see them smoking pipes and cigarettes surrounded by smoke. In an exhibition of portraits of Norwegian Authors, ten out of seventy authors were portrayed with a pipe, a cigar or a cigarette. There are various interpretations of the use of smoking in art. A simple explanation is that this was an accepted part of life at that time. The authors may have believed that they concentrated better when they smoked and elegance may have been of importance for many of them. The symbolic significance of cigarette-smoking has been of great value in the marketing of tobacco-products.

    With about 2000 exoplanets discovered within a large range of different configurations of distance from the star, size, mass, and atmospheric conditions, the concept of habitability cannot rely only on the stellar effective temperature anymore. In addition to the natural evolution of habitability with the intrinsic stellar parameters, tidal, magnetic, and atmospheric interactions are believed to have strong impact on the relative position of the planets inside the so-called habitable zone. Moreover, the notion of habitability itself strongly depends on the definition we give to the term "habitable". The aim of this contribution is to provide a global and up-to-date overview of the work done during the last few years about the description and the modelling of the habitability, and to present the physical processes currently includes in this description.

    2016-01-01

    As the proverbial creatures of habit, people tend to repeat the same behaviors in recurring contexts. This review characterizes habits in terms of their cognitive, motivational, and neurobiological properties. In so doing, we identify three ways that habits interface with deliberate goal pursuit: First, habits form as people pursue goals by repeating the same responses in a given context. Second, as outlined in computational models, habits and deliberate goal pursuit guide actions synergistically, although habits are the efficient, default mode of response. Third, people tend to infer from the frequency of habit performance that the behavior must have been intended. We conclude by applying insights from habit research to understand stress and addiction as well as the design of effective interventions to change health and consumer behaviors.

In present study, we detected relationship between cigarette smoking habits and serum lipid/lipoprotein (serum Triglyceride (TG, Total cholesterol (TC, Low-density lipoprotein (LDL and high-density lipoprotein (HDL among Chinese Nonagenarians/Centenarian. Methods The present study analyzed data from the survey that was conducted on all residents aged 90 years or more in a district, there were 2,311,709 inhabitants in 2005. Unpaired Student’s t test, χ2 test, and multiple logistic regression were used to analyze datas. Results The individuals included in the statistical analysis were 216 men and 445 women. Current smokers had lower level of TC (4.05 ± 0.81 vs. 4.21 ± 0.87, t = 2.403, P = 0.017 and lower prevalence of hypercholesteremia (9.62% vs. 15.13%, χ2 = 3.018,P = 0.049 than nonsmokers. Unadjusted and adjusted multiple logistic regressions showed that cigarette smoking was not associated with risk for abnormal serum lipid/lipoprotein. Conclusions In summary, we found that among Chinese nonagenarians/centenarians, cigarette smoking habits were not associated with increased risk for dyslipidemia, which was different from the association of smoking habits with dyslipidemia in general population.

    Full Text Available Objective: We aimed to evaluate smoking habits of students, reasons of smoking and students’ level of knowledge on the adverse effects of smoking in a state high school in İstanbul. Methods: A 15-item questionnaire was administered to the students attending a state high school in İstanbul to evaluate their attitudes and behaviors towards cigarette smoking. The questionnaire was completed by each class of students at the same class period under the supervision of their teachers. Results: The questionnaire was completed by 415 students at the respective school. While 349 students (84% never smoke, 66 (15.9% students were either current smokers or quitters. Fifty five of the students (13.2% were active smokers. When we looked at the reasons of smoking, they reported that 63.6% smoked cigarettes because their friends did; 47.2% smoked cigarettes due to exam-related stress; and 40% smoked cigarettes due to family problems. The rate of smoking friends in the smoker group was significantly higher than in the non-smoker group (p=0.0001. A logistic regression analysis showed that having smoking friends was associated with an 8-fold increase in the risk of smoking compared to having no smoking friends. Conclusion: The most common reasons of smoking at the school were friends who were smokers, exam-related stress and family problems. Having friends who smoke was associated with an 8-fold increase in the risk of smoking. We believe that counselling services’ close engagement with family problems of students and exam-related stress issues and helping them to cope with these problems may prevent their vulnerability to toxic substances.

  10. Lifestyle Issues in Inflammatory Bowel Disease – Smoking

    Cecilia Benoni

    1994-01-01

    Full Text Available During the pa t decade, smoking habit has been identified as a major exogenous factor in inflammatory bowel disease (IBD. It is associated not only with the development of the disease but al o with the clinical course in established disease. IBD combines absolute opposites as smoking is associated with Crohn’s disease and nonsmoking or former smoking with ulcerative colitis. The first reports of a negative association between smoking and ulcerative colitis were based on independent, clinical observations; from those studies a positive association was found between smoking and Crohn’s disease. Epidemiological studies that followed consistently showed that smokers have a reduced risk of ulcerative colitis and an increased risk of Crohn’s disease and that exsmokers have an increased risk of ulcerative colitis. In ulcerative colitis, but not in Crohn’s disease, a dose-response pattern has been demonstrated. Changes in clinical course, in disease severity and extension, and in recurrence rate indicate substantial clinical effects of smoking with a protective effect of smoking in ulcerative colitis and an aggravating effect in Crohn’s disease. There are also indications of smoking’s effects on changes in IBD epidemiology and sex distribution. The biological explanation to the finding is unknown. Smoking may aggravate Crohn’s disease by vascular effects. Theories on the protective effect in ulcerative colitis include effects on immune and inflammatory response, on mucus and on intestinal permeability. Possibly, beneficial effects in ulcerative colitis are exerted by nicotine but further studies are needed. Due to overall negative effects of smoking, IBD patients should not smoke. It seems, however, reasonable to give individual advice in patients with ulcerative colitis who have experienced a beneficial effect of ·making considering both current health status and life situation.

Thirty-seven per cent of pregnant women were smoking and only one in four of these was successful at stopping at some point during pregnancy. However, 55 per cent of the mothers who smoked at the start of pregnancy claimed to smoke less during pregnancy. No change was reported in the habits of one-quarter of the mothers who smoked during pregnancy and this proportion may represent an 'irreducible minimum'. Mothers were more likely to continue to smoke if younger (14-20 years), single, living with a partner who smoked, who left school at 16 years and were from manual working families. Those who succeeded in giving up smoking during pregnancy were more likely to be from professional and managerial families. Antenatal booklets about the dangers of smoking were the source of information cited most frequently. Half of the smoking mothers claimed not to have received advice from their family practitioners about the hazards of smoking nor information about how to give up the habit. Even fewer received such advice from hospital doctors, or midwives. This represents a major challenge to professional training in health education.

    Tobacco use is a leading preventable cause of morbidity and mortality, with nearly 6 million deaths caused by tobacco use worldwide every year (1). Cigarette smoking is the most common form of tobacco use in most countries, and the majority of adult smokers initiate smoking before age 18 years (2,3). Limiting access to cigarettes among youths is an effective strategy to curb the tobacco epidemic by preventing smoking initiation and reducing the number of new smokers (3,4). CDC used the Global Youth Tobacco Survey (GYTS) data from 45 countries to examine the prevalence of current cigarette smoking, purchase of cigarettes from retail outlets, and type of cigarette purchases made among school students aged 13-15 years. The results are presented by the six World Health Organization (WHO) regions: African Region (AFR); Eastern Mediterranean Region (EMR); European Region (EUR); Region of the Americas (AMR); South-East Asian Region (SEAR); and Western Pacific Region (WPR). Across all 45 countries, the median overall current cigarette smoking prevalence among students aged 13-15 years was 6.8% (range = 1.7% [Kazakhstan]-28.9% [Timor-Leste]); the median prevalence among boys was 9.7% (2.0% [Kazakhstan]-53.5% [Timor-Leste]), and among girls was 3.5% (0.0% [Bangladesh]-26.3% [Italy]). The proportion of current cigarette smokers aged 13-15 years who reported purchasing cigarettes from a retail outlet such as a store, street vendor, or kiosk during the past 30 days ranged from 14.9% [Latvia] to 95.1% [Montenegro], and in approximately half the countries, exceeded 50%. In the majority of countries assessed in AFR and SEAR, approximately 40% of cigarette smokers aged 13-15 years reported purchasing individual cigarettes. Approximately half of smokers in all but one country assessed in EUR reported purchasing cigarettes in packs. These findings could be used by countries to inform tobacco control strategies in the retail environment to reduce and prevent marketing and sales of

    Full Text Available Abstract Background Among military personnel alcohol consumption and binge-drinking have increased but cigarette smoking has declined in the recent past. Although there is a strong association between smoking and PTSD the association between combat exposure and smoking is not clear. Methods This cross sectional study was carried out among representative samples of SLN Special Forces and regular forces deployed in combat areas. Both Special Forces and regular forces were selected using simple random sampling. Only personnel who had served continuously in combat areas during the one year period prior to end of combat operations were included in the study. Females were not included in the sample. The study assessed several mental health outcomes as well as alcohol use, smoking and cannabis use. Sample was classified according to smoking habits as never smokers, past smokers (those who had smoked in the past but not within the past year and current smokers (those smoking at least one cigarette within the past 12 months. Results Sample consisted of 259 Special Forces and 412 regular navy personnel. Prevalence of current smoking was 17.9% (95% CI 14.9-20.8. Of the sample 58.4% had never smoked and 23.7% were past smokers. Prevalence of current smoking was significantly higher among Special Forces personnel compared to regular forces. (OR 1.90 (95% CI 1.20-3.02. Personnel aged ≥35 years had the lowest prevalence of smoking (14.0%. Commissioned officers had a lower prevalence (12.1% than non commissioned officers or other ranks.

    Full Text Available Background: Smoking is a recognized harmful factor for general health. The prevalence of smoking is gradually increasing among the young people. Medical students are also vulnerable in this arena. Worldwide studies revealed that students start and continue smoking during their school and college periods. Objectives: To determine the current tobacco use among medical college students and to find out the risk factors associated with smoking and also to assess the knowledge of students regarding smoking. Materials and Methods: This cross-sectional study was conducted among medical students of different educational levels (first year to fifth year in Enam Medical College, Savar, Dhaka during the period January to March 2012. An anonymous, pretested, selfadministered study questionnaire was distributed among the subjects. Data collected included smoking habits, demographic factors such as age, gender, parents’ occupation and monthly income. Study subjects were categorized as smokers, non-smokers and ex-smokers. Smoking-related knowledge was assessed and opinion regarding cessation of smoking was documented. The data were entered into the computer and statistical analyses were done using GraphPad Prism version 6.01. Results: Among the study subjects 290 were male and 202 were female.

    The objective of this cross-sectional study is to examine the association between religious involvement and tobacco use in a large representative sample of users of primary healthcare units of Ribeirão Preto, Southeast Brazil. Current and past smoking habits were determined among 1055 users of primary healthcare units. Participants' religiosity was measured using the DUREL questionnaire. The prevalence of smoking among men was 16.8% [95% confidence interval (CI) 12.0-22.5] and among women was 12.6% (95% CI 10.4-15.0). Among the current smokers, 40.9% were light smokers, 24.6% were moderate smokers, and 34.5% were heavy smokers. The mean number of cigarettes smoked per day was 13.5. Respondents who have a religion had a lower smoking prevalence than people who had no religion. Current smoking prevalence tended to be higher among people who do not practice their religion than people who practice their religion. Smoking status is also associated with self-reported religiosity, organizational religious activity and some aspects of intrinsic religiosity. Religiosity is an important factor in influencing the smoking behavior in Brazilian users of the public health services.

    Smoking during pregnancy (active or passive) is associated with increased health risks to the unborn child. Current policy on antismoking advice for pregnant women in the United Kingdom is based essentially on written information by means of leaflets given to them at the first antenatal visit. We evaluated the impact of this policy on the smoking habits of pregnant women. A sample of 180 women with planned pregnancies attending antenatal clinics at two teaching hospitals in North London was recruited over a 6-month period. All women were provided with the current antismoking counselling at their first visit at the end of the first trimester and asked to fill in a questionnaire around mid-gestation. The study population included 117 (65%) women who did not currently smoke (non-smokers) and 63 (35%) who were active smokers at the beginning of their pregnancy. Thirty-nine non-smokers were found to be passive smokers. Three women took up smoking during pregnancy. Among the smokers, 53 (84.1%) women made no change in their smoking behaviour during pregnancy, seven (11.1%) reduced their cigarette consumption and only three (4.8%) gave up smoking during the first half of pregnancy. None of the partners changed their smoking habits. All women were aware that smoking in pregnancy could be deleterious to their health and that of their fetus. Despite awareness of dangers of smoking, the prevalence of smoking among pregnant women remains very high after the first antenatal visit and the current antismoking policy based essentially on leaflets is not effective. Health-care professionals should spend more time to inform women adequately about the dangers of smoking and help them to quit before pregnancy.

    We combine a semi-analytic model of galaxy evolution with constraints on circumstellar habitable zones and the distribution of terrestrial planets to probe the suitability of galaxies of different mass and type to host habitable planets, and how it evolves with time. We find that the fraction of stars with terrestrial planets in their habitable zone (known as habitability) depends only weakly on galaxy mass, with a maximum around 4e10 Msun. We estimate that 0.7% of all stars in Milky Way type...

    Long term habitability on the surface of planets has as a prerequisite a minimum availability of elements to build rocky planets, their atmospheres, and for life sustaining water. They must be within the habitable zone and avoid circumstances that cause them to lose their atmospheres and water. However, many astrophysical sources are hazardous to life on the surfaces of planets. Planets in harsh environments may require strong magnetic fields to protect their biospheres from high energy particles from the host star(s). Planets in harsh environments may additionally require a strong astrosphere to be sufficiently able to deflect galactic cosmic-rays. Supernovae (SNe) play a central role in the habitability of planets in the disks of star forming galaxies. Currently, the SNe rate maintains a relativistic galactic wind shielding planets in the disk from extragalactic cosmic rays. However, if the density of SNe in the disk of the galaxy were significantly higher, as it was 6-8 GYA, the frequency of nearby catastrophic events and often prolonged harsh environment may have strongly constrained life in the early history of the Milky Way. Active galactic nuclei (AGN) may remain quiescent for hundreds of millions of years only to activate for some time due extraordinary accretion episode due to for instance a galactic merger. The starburst galaxy M82 is currently undergoing a merger, probably strongly compromising habitability within that galaxy. The giant elliptical M87 resides in the center of the Virgo supercluster and has probably consumed many such spiral galaxies. We show that super-Eddington accretion onto the supermassive black hole in M87, even for a short while, could compromise the habitability for a large portion of the central supercluster. We discuss environments where these effects may be mitigated.

    Tobacco smoking is a major cause of lung cancer. It has been suggested that there is an approximately linear dose–response relationship between the number of cigarettes smoked per day and clinical outcome such as lung cancer mortality. It has also been proposed that there is a greater increase in mortality at high doses when the dose is represented by the duration of the smoking habit rather than the number of cigarettes. The multistep carcinogenesis theory indicates that a greater increase i...

    To estimate the prevalence of smoking among Brazilian youth, examining individual, family, and social group factors associated with this habit. Data from youth aged 15 to 24 years living in 17 Brazilian state capitals and the Federal District, obtained from the Household Survey on Risk Factors for Chronic Diseases and Reported Morbidity carried out in 2002 and 2003 by the National Cancer Institute was analyzed. Individual variables (sex, age, schooling, alcohol consumption, self-rated health, physical activity, current school attendance), family variables (age and education of head of household and father, mother, or sibling smoking), and social group variables (best friend smoking, most friends smoking, boyfriend/girlfriend smoking) were analyzed. Generalized estimating equations (GEE) approach to evaluate the factors associated with smoking were used. Considering the effect of the sampling design, smoking prevalence was 12.8%, ranging from 6.8% in Aracaju to 24.1% in Porto Alegre. The following factors were predictors of smoking: male sex, older age, less schooling, not attending school at the time of the survey, poorer health perception, and alcohol consumption. Peer smoking (friends or boyfriend/girlfriend) and smoking among family members (father/mother or sibling) were associated with smoking. There was an effect of parental birth cohort on smoking, with a higher prevalence of smoking among youth whose parents were born in the 1930s. Individual characteristics and the influence of peers and family were relevant for smoking by the youth. Increasing the dialogue among teenagers, school, schoolmates, friends, and parents could lead to a reduction of substance use among youth.

    óvenes en el control del tabaquismo.This study was aimed at evaluating the degree of smoking dependence and to characterize social demographic data, habits and attitudes of young smokers. Answered the questionnaire102 students from Salvador, State of Bahia, of which 11 were smokers. Their mean age and the age in which they first smoked were 18.2 and 13.4 years respectively. Most of them were male, in the first year of senior high school, of brown skin color and had close relatives who smoke. The majority of those young smokers had been advised about the risks of smoking at home and in school, but few had knowledge about the benefits of quitting. Almost half of them had been smoking for more than three years and had started to smoke out of curiosity. More than half of them smoked one cigarette per day, with low levels of nicotine, bought the cigarettes in shops, and wanted and tried to quit smoking, but never succeeded. The degree of dependence was low for most of them. This study offers hints for nurses to act against smoking with young adults.

    Water pipe is a traditional method of tobacco use, which is epidemically spreading throughout Europe. There are scarce data about the use of water pipe and its relation to other addictive behaviors among young adults in Western countries. It was our aim to identify the sociodemographic characteristics of water pipe users in Switzerland and to describe concurrent cigarette and cannabis smoking habits. Young adults aged 16-30 years were evaluated based on a 16-item standardized questionnaire on tobacco consumption and exhaled carbon monoxide. Current water pipe smoking was defined as water pipe use at least once within the last 4 weeks; regular water pipe smoking was defined as water pipe use at least once a week during the last 52 weeks. Out of 353 volunteers, a total of 204 subjects (mean age 21 ± 3.5 years, 113 males) met the inclusion criteria for the study. A total of 78% (n = 160), 30.0% (n = 55) and 3.9% (n = 8) reported ever, current and regular water pipe smoking, respectively. Males smoked more often than females: 2.8 sessions/year (interquartile range 1.1-8) versus 2 sessions/year (interquartile range 0-4; p = 0.022). The major risk factor for ever smoking water pipe was cigarette smoking (odds ratio 6.22, 95% confidence interval 2.33-16.62), followed by cannabis consumption (odds ratio 1.44, 95% confidence interval 1.29-1.62). Ever water pipe smoking was more common among current cannabis users (100 vs. 0%; p pipe smoking is common among young adults and strongly associated with cigarette smoking and cannabis consumption.

    Chronic pancreatitis (CP) has a profound independent effect on quality of life (QOL). Our aim was to identify factors that impact the QOL in CP patients. We used data on 1,024 CP patients enrolled in the three NAPS2 studies. Information on demographics, risk factors, co-morbidities, disease phenotype, and treatments was obtained from responses to structured questionnaires. Physical and mental component summary (PCS and MCS, respectively) scores generated using responses to the Short Form-12 (SF-12) survey were used to assess QOL at enrollment. Multivariable linear regression models determined independent predictors of QOL. Mean PCS and MCS scores were 36.7±11.7 and 42.4±12.2, respectively. Significant (Punemployment (5.1), current smoking (2.9 points), and medical co-morbidities. Significant (Punemployment (2.4 points). In women, disability/unemployment resulted in an additional 3.7 point reduction in MCS score. Final multivariable models explained 27% and 18% of the variance in PCS and MCS scores, respectively. Etiology, disease duration, pancreatic morphology, diabetes, exocrine insufficiency, and prior endotherapy/pancreatic surgery had no significant independent effect on QOL. Constant pain, pain-related disability/unemployment, current smoking, and concurrent co-morbidities significantly affect the QOL in CP. Further research is needed to identify factors impacting QOL not explained by our analyses.

    This study describes the prevalence of reported history of traumatic brain injury (TBI) and its association with reports of current substance use, cigarette smoking, and psychological distress among Canadian adults in a population sample. A cross-sectional sample of 1999 Ontario adults 18-93 years of age were surveyed by telephone in 2011 as part of the Center for Addiction and Mental Health's ongoing representative survey of adult mental health and substance use in Ontario, Canada. Loss of consciousness for at least 5 min or at least one overnight hospitalization resulting from symptoms associated with the TBI injury represented minimum criteria for TBI. An estimated 16.8% (95% confidence interval, 14.8, 19.0) of adults reported a TBI in their lifetime. Men had higher prevalence of TBI than women. Adults who reported a history of TBI had higher odds of reported past-year daily smoking (adjusted odds ratio [AOR] = 2.15), using cannabis (AOR = 2.80) and nonmedical opioids (AOR = 2.90), as well as screened significantly for recent elevated psychological distress (AOR = 1.97) in the past few weeks, compared to adults without a history of TBI. Co-occurrence of a history of TBI with current elevated psychological distress and substance use warrants vigilance among medical practitioners to assess the possibility of a history of TBI during reviews of the history leading to the occurrence of these conditions.

    The pedodontic admission histories of 1600 Mexican children were analyzed, to determine general epidemiologic factors or oral habits, as well as their relationship with identifiable biopsychosociologic factors. Fifty-six percent of the children gave evidence of an oral habit, with significant predisposition among female patients, single children, subjects in poor physical health (particularly from allergies), as well as children with histories of chronic health problems. Oral habits should be considered a major health hazard because of their high incidence. Successful treatment requires a multidisciplinary approach to the basic cause of the problem.

    To examine trends in the relationship between smoking history and both general and central fatness in adults from a Mediterranean setting. Materials and methods: The ENCAT 1992-1993 and 2002-2003 surveys were used; samples consisted of 482 men, 589 women from 1992-1993, and 515 men, 613 women from 2002-2003, aged 25-60 years. Measured anthropometry and self-reported data on smoking habits, diet, lifestyle and SES were collected. General fatness was defined as WHO's BMI overweight and obesity, and central fatness was defined as WHO's Increased-Risk-for-metabolic-complications Waist Circumference (IR WC) and Substantially-Increased-Risk WC (SIR WC). Simple logistic regression was used to estimate multivariate-adjusted associations between general/central fatness and smoking history. By 2002-2003, most associations observed in 1992-1993 had been strongly attenuated: only male current-heavy-smoking remained associated with IR/SIR WC (three-fold) and female current-moderate-smokers were 0.57 times less likely to have an IR/SIR WC (p < 0.10). Although causality cannot be established, results suggest a positive association between heavy smoking and central fatness among men, but no association between former smoking and general/central fatness; findings strengthen arguments for promoting smoking cessation to reduce smoking -and obesity- associated morbidity and mortality.

    Smith, Derek R

    2007-09-01

    This study was conducted to systematically and critically evaluate the large number of academic publications which have investigated tobacco smoking among nursing students in recent years. It was performed as a state-of-the-art examination of all modern literature published in peer-reviewed, English-language journals since 1990. Although smoking appears to be fairly common among nursing students, its prevalence and distribution varies widely depending on the country of study and time period during which the research was undertaken. Although there is some evidence to suggest that smoking rates increase by year of study in the nursing course, not all research has shown a clear association in this regard. Similarly, the value of anti-smoking interventions for nursing students appears to be limited, based on currently available information. Given these conflicting issues, further research which helps to ascertain why student nurses do not wish to give up their habit is clearly needed both locally and internationally. The development of an international smoking questionnaire may also be useful to help standardize future research on tobacco usage among this vulnerable demographic.

    To describe smokers' participation in cigarette continuity programs and the prevalence and structure of cooperative teams of smokers. Cross-sectional survey of smoking histories and continuity-program participation by individuals and their family members in a convenience sample of 176 current smokers at the University of Kentucky Chandler Medical Center, Lexington. Fisher exact test or chi2 tests were used to compare proportions. One of 3 smokers collected coupons for a continuity program. Three quarters of the collectors redeemed their own coupons, and one quarter gave coupons to another collector. Coupon collectors reported an average team size of more than 2 members. One fifth of collectors were teammates with another generation of family members, and one quarter of collectors aged 24 to 35 years were teammates with their children. Smokers were often aware of their relatives' coupon-collecting habits. Continuity programs have been a popular means of reinforcing smoking, especially within families and groups of friends. Continuity programs are novel in encouraging smoking and brand loyalty between generations. Continuity-program participants need to be aware of the risk of promoting smoking initiation by their children. Health advocates could use similar strategies to promote smoking cessation and prevention within families and other social groups.

    This study examined availability and usage of tobacco products, and their potential impact on the oral health of naval personnel deployed to Desert Storm. Of 4,200 surveys mailed to a randomly selected sample, 45.6% were returned (N = 1,915). The respondents included 55.9% who reported a present or former smoking habit, 34.1% who identified themselves as current smokers (SM), and 23.8% who were smokeless tobacco (ST) users. Tobacco products were easily and inexpensively accessible through ship stores, exchange, or military support organizations (USO). While in the Persian Gulf, 7.0% started SM and 9.3% started ST, resulting in an overall 4.7 and 6.1% increase in SM and ST, respectively. Of those who were already tobacco users, 29.2% reported more SM use and 19.0% used ST more often. Stress (35.1%) and boredom (21.4%) were the most frequently cited reasons to start or increase use. Although 30.5% of respondents reported military personnel have encouraged them to quit, 77.2% reported that anti-smoking efforts have been unsuccessful in influencing them to quit. Since the tobacco usage rate is higher in the military than in the civilian sector, greater emphasis on preventive efforts in warranted to promote health and wellness.

    In this study, the risk factors that may influence visual improvement after intravitreal ranibizumab (IVR) treatment for exudative age-related macular degeneration (AMD) were examined. From 2008 to 2012, 420 patients (448 eyes) with exudative AMD were prospectively registered at Seoul National University Hospital. From this group of patients, 125 eyes were included in this study. All patients were treated with 3 consecutive IVR injections. The visual acuity (VA) was evaluated at baseline and 1 month after the third ranibizumab injection. To evaluate the risk factors associated with VA improvement after IVR, patient demographic data and systemic risk factors were analyzed. Patients were divided into a poor VA improvement group and a good VA improvement group, with reference to the median visual improvement in all eyes. Among 125 eyes, 66 eyes (52.8%) were included in the responder group and 59 eyes (47.2%) in the non-responder group. The median VA improvement after 3 monthly ranibizumab injections was -0.05 logMAR. Multivariate analyses revealed that current smoking (adjusted OR, 7.540; 95% CI, 1.732-32.823) was independently associated with poor VA improvement after IVR treatment for exudative AMD. In conclusion, cigarette smoking is an independent risk factor for lower VA gains with IVR treatment for exudative AMD.

    The tendencies in the cessation from smoking and their determinants provide useful information to developed preventive policies and to predict the evolution of diseases associated with cigarette consumption. Spain is one of the European countries with more prevalent smoking habits in the general population, and thus the study of factors determining cessation from smoking is particularly relevant. The socioeconomic, demographic and health-related variables associated with the cessation from smoking were evaluated using the data bank from the National Health Survey carried out by the Ministerio de Sanidad y Consumo in 1987, which includes interviews to 29,647 individuals above 16 years of age. The data were analyzed by the calculation of the quit ratio standardized for age. The quit ratio is influenced by age and sex; it is higher among women and it increases with age. The results are questionable regarding the relation with educational level, family income and occupation. The smokers of less than 10 or more than 25 cigarettes/day are those with a higher quit ratio. The quit ratio is also higher in individuals with health problems, a higher rate of use of health services and in those without usual alcohol consumption. The profile of the individuals who quit smoking in Spain has specific features when compared with other countries, particularly regarding the higher quit rate among women and the lack of a linear correlation with indicators of socioeconomic level.

    During 1988 to 1989 the NASA/USRA Advanced Design Program sponsored research and design efforts aimed at developing habitability criteria and at defining a habitability concept as a useful tool in understanding and evaluating dwellings for prolonged stays in extraterrestrial space. The Circulating Auto sufficient Mars-Earth Luxurious Orbital Transport (CAMELOT) was studied as a case in which the students would try to enhance the quality of life of the inhabitants by applying architectural design methodology. The study proposed 14 habitability criteria considered necessary to fulfill the defined habitability concept, which is that state of equilibrium that results from the interaction between components of the Individual Architecture Mission Complex, which allows a person to sustain physiological homeostatis, adequate performance, and acceptable social relationships. Architecture, design development, refinements and revisions to improve the quality of life, new insights on artificial gravity, form and constitution problems, and the final design concept are covered.

    Oral habits, if persist beyond certain developmental age, can pose great harm to the developing teeth, occlusion, and surrounding oral tissues. In the formative years, almost all children engage in some non-nutritive sucking habits. Clinicians, by proper differential diagnosis and thorough understanding of natural growth and developmental processes, should take a decision for intervening. This article describes case series reports of thumb sucking, finger sucking, and tongue thrusting habits, which have been successfully treated by both removable and fixed orthodontic appliances. The cases shown are ranging from the age group of 9-19 years presenting combination of both mixed and permanent dentition development. All cases show satisfactory correction of habits and stable results.

    Jarvis, M.J.; Russell, M.A.; Feyerabend, C.; Eiser, J.R.; Morgan, M.; Gammage, P.; Gray, E.M.

    1985-10-05

    Saliva cotinine concentrations in 569 non-smoking schoolchildren were strongly related to the smoking habits of their parents. When neither parent smoked the mean concentration was 0.44 ng/ml, rising to 3.38 ng/ml when both parents were cigarette smokers. Mothers smoking had a stronger influence than did fathers (p less than 0.01). In addition, there was a small independent effect of number of siblings who smoked (p less than 0.01). The dose of nicotine received from fathers smoking was estimated as equivalent to the active smoking of 30 cigarettes a year, that from mothers smoking as equivalent to smoking 50 cigarettes a year, and that from both parents smoking as equivalent to smoking 80 cigarettes a year. This unsolicited burden may be prolonged throughout childhood and poses a definite risk to health.

  13. High on habits

    Full Text Available The neural circuits involved in learning and executing goal-directed actions, which are governed by action-outcome contingencies and sensitive to changes in the expected value of the outcome, have been shown to be different from those mediating habits, which are less dependent on action-outcome relations and changes in outcome value. Extended training, different reinforcement schedules, and substances of abuse have been shown to induce a shift from goal-directed performance to habitual performance. This shift can be beneficial in everyday life, but can also lead to loss of voluntary control and compulsive behavior, namely during drug seeking in addiction. Although the brain circuits underlying habit formation are becoming clearer, the molecular mechanisms underlying habit formation are still not understood. Here, we review a recent study where Hilario et al. established behavioral procedures to investigate habit formation in mice in order to investigate the molecular mechanisms underlying habit formation. Using those procedures, and a combination of genetic and pharmacological tools, the authors showed that endocannabinoid signaling is critical for habit formation.

    Terrestrial planets are more likely to be detected if they orbit M dwarfs due to the favorable planet/star size and mass ratios. However, M dwarf habitable zones are significantly closer to the star than the one around our Sun, which leads to different requirements for planetary habitability and its detection. We review 1) the current limits to detection, 2) the role of M dwarf spectral energy distributions on atmospheric chemistry, 3) tidal effects, stressing that tidal locking is not synonymous with synchronous rotation, 4) the role of atmospheric mass loss and propose that some habitable worlds may be the volatile-rich, evaporated cores of giant planets, and 5) the role of planetary rotation and magnetic field generation, emphasizing that slow rotation does not preclude strong magnetic fields and their shielding of the surface from stellar activity. Finally we present preliminary findings of the NASA Astrobiology Institute's workshop "Revisiting the Habitable Zone." We assess the recently-announced planet ...

    Smoking has always been a huge problem in Malaysia and its surrounding nations. The purpose of this study was to determine the prevalence of cigarette smoking and to identify the influencing factors associated with smoking habits among adolescents. This cross-sectional study was carried out on 226 respondents, using a questionnaire which had 4 sections: socio-demographic data, personal information, family information and social information. Data was analyzed using SPSS® version 16. For categorical variables, comparisons were made using Chi-square and for numerical variables a t-test was performed. The current smoker prevalence rate was 20.8% which showed a significant association between smoking and individual factors: level of knowledge on the effects of smoking (p < 0.05), significant association was seen between smoking and marital status of parents, smoking status of male siblings and various other aspects of the individuals themselves. Concerted efforts involving various parties should be taken to curb or prevent this problem or the number of teenage smokers in the country will increase. This in the long run will invite problems to the well being of the adolescents themselves, their families, community and the nation as a whole.

    The main objectives of this paper were to estimate the consumption patterns of tobacco use among King Saud University (KSU) undergraduate students; and investigate different risk factors which may contribute to tobacco use among female students. A representative sample (n=7550) of the total KSU undergraduate student population of 69,498 (males and females) was selected, stratified according to college and gender. A modified version of the WHO/CDC Global Youth Tobacco Survey (GYTS) questionnaire was used for data collection. Overall smoking prevalence among KSU students was estimated at 14.5%, prevalence among male students (32.7%), and females (5.9%). Independent risk factors for smoking among males were found to be: age, father's smoking habits, and "friends' smoking habits"; while among females were: sister's smoking habits and "friends' smoking habits." The findings of this study re-emphasize the significance of peer pressure on smoking among university students of both sexes; influence of family members, usually of same sex. We need to foster gender-sensitive tobacco prevention intervention programs, to prevent youngsters of both sexes from taking up such habit. We also need to raise awareness of girls and young women, of the consequences of smoking in general, water-pipe in specific, on their own health, that of their spouses, families, and off-springs, many of whom could develop chronic respiratory disorders, as passive smokers in the beginning/potential smokers themselves, later on. All such efforts should be backed and supported by strong governmental commitment, to ensure success of their implementation accordingly. Crown Copyright © 2010. Published by Elsevier Ltd.

  18. Age aspects of habitability

    A `habitable zone' of a star is defined as a range of orbits within which a rocky planet can support liquid water on its surface. The most intriguing question driving the search for habitable planets is whether they host life. But is the age of the planet important for its habitability? If we define habitability as the ability of a planet to beget life, then probably it is not. After all, life on Earth has developed within only ~800 Myr after its formation - the carbon isotope change detected in the oldest rocks indicates the existence of already active life at least 3.8 Gyr ago. If, however, we define habitability as our ability to detect life on the surface of exoplanets, then age becomes a crucial parameter. Only after life had evolved sufficiently complex to change its environment on a planetary scale, can we detect it remotely through its imprint on the atmosphere - the so-called biosignatures, out of which the photosynthetic oxygen is the most prominent indicator of developed (complex) life as we know it. Thus, photosynthesis is a powerful biogenic engine that is known to have changed our planet's global atmospheric properties. The importance of planetary age for the detectability of life as we know it follows from the fact that this primary process, photosynthesis, is endothermic with an activation energy higher than temperatures in habitable zones, and is sensitive to the particular thermal conditions of the planet. Therefore, the onset of photosynthesis on planets in habitable zones may take much longer time than the planetary age. The knowledge of the age of a planet is necessary for developing a strategy to search for exoplanets carrying complex (developed) life - many confirmed potentially habitable planets are too young (orbiting Population I stars) and may not have had enough time to develop and/or sustain detectable life. In the last decade, many planets orbiting old (9-13 Gyr) metal-poor Population II stars have been discovered. Such planets had had

    2010-01-01

    In many industrialized countries smokers have been observed in high prevalence among workers with poor educational status, who are usually exposed to major occupational risks. The smoking habit and passive smoking may by themselves, or through interactions with other occupational risk factors, cause the onset of serious diseases. Therefore health reasons and the legal obligation to observe the smoking ban in the workplace make it essential to prevent and combat smoking in the workplace and to promote smoking cessation in workers who smoke. This initiative should benefit not only workers' health and well-being but also company finances. The Occupational Physician should engage in diverse activities ranging from encouraging young people not to start smoking to providing programmes to encourage workers who smoke to abandon the habit. For example, he or she should i) inform managers, supervisors and workers about the high risks linked to smoking, passive smoking and obligations established by law ii) collect information about the smoking habit among workers and supply workers with the so-called minimal clinical intervention during routine health surveillance appointments and iii) collaborate with specific health promotion programmes in the workplace.

    Full Text Available Abstract Background Smoking is a significant women's health issue. Examining smoking behaviors among occupational groups with a high prevalence of women may reveal the culture of smoking behavior and quit efforts of female smokers. The purpose of this study was to examine how smoking and quitting characteristics (i.e., ever and recent quit attempts among females in the occupation of nursing are similar or different to those of women in the general population. Methods Cross-sectional data from the Tobacco Use Supplement of the Current Population Survey 2006/2007 were used to compare smoking behaviors of nurses (n = 2, 566 to those of non-healthcare professional women (n = 93, 717. Smoking characteristics included years of smoking, number of cigarettes, and time to first cigarette with smoking within the first 30 minutes as an indicator of nicotine dependence. Logistic regression models using replicate weights were used to determine correlates of ever and previous 12 months quit attempts. Results Nurses had a lower smoking prevalence than other women (12.1% vs 16.6%, p p = 0.0002; but not in the previous 12 months (42% vs 43%, p = 0.77. Among those who ever made a quit attempt, nurses who smoked within 30 minutes of waking, were more likely to have made a quit attempt compared to other women (OR = 3.1, 95% CI: 1.9, 5.1. When considering quit attempts within the last 12 months, nurses whose first cigarette was after 30 minutes of waking were less likely to have made a quit attempt compared to other females (OR = 0.69, 95% CI: 0.49, 0.98. There were no other significant differences in ever/recent quitting. Conclusions Smoking prevalence among female nurses was lower than among women who were not in healthcare occupations, as expected. The lack of difference in recent quit efforts among female nurses as compared to other female smokers has not been previously reported. The link between lower level of nicotine dependence, as reflected by the longer

    Despite smoking cessation efforts, cigarette smoking remains a serious general and oral health problem. We aimed to investigate the putative benefits of smoking cessation on dentition and to analyse whether the time elapsed since smoking cessation associated positively with the remaining number of teeth. This cross-sectional study analyses data from the 46-year follow-up of the Northern Finland Birth Cohort Study 1966 (NFBC1966). A total of 5 540 subjects participated in this cross-sectional study, which utilises both clinical dental examinations and mailed questionnaires. We used the following information on smoking: status (current, former, never), years of smoking (current, former) and years elapsed since smoking cessation (former). Self-reported and clinically measured number of teeth (including third molars) served as alternative outcomes. We used binary logistic regression models to analyse the dichotomised number of teeth ('0-27', '28-32') and then calculated unadjusted and adjusted odds ratios (OR) with 95 % confidence intervals (CI) for the smoking variables (never smoker as the reference). Gender, education, tooth brushing frequency, diabetes and alcohol use served as confounders for the adjusted models. Ten years or more of smoking associated with tooth loss; this effect was the strongest among men who reported having an ongoing smoking habit (self-reported outcome: adjusted OR = 1.74, CI = 1.40-2.16) and the weakest among women classified as former smokers (self-reported outcome: adjusted OR = 1.27, CI = 1.00-1.62). This study shows that smoking has long-term effects on tooth loss even after cessation. The findings support smoking cessation efforts to reduce oral health risks.

    Full Text Available The aim was to explore the prevalence and the correlates of smoking in a group of Turkish university students. A sample of 1,870 students (21.2 ± 2.0 years old completed the Beck Depression Inventory, Beck Hopelessness Scale, Anxiety Sensitivity Index, 20-item Toronto Alexithymia Scale. Smoking was highly prevalent (35.9% in this sample. Male gender (OR = 2.72, CI 2.15-3.44, and parental smoking (OR = 1.41, CI 1.13-1.78 were factors associated with increased likelihood of smoking. Higher depressive symptoms and hopelessness levels were significantly related to smoking behavior. Smoking behavior might initiate as a mild and transient habit and unfortunately could become more serious and lead to an actual dependence. The results of this study show that it is necessary to pay attention to levels of depression and hopelessness, as well as parental influence.

    This review focuses on recent results in advancing our understanding of the location and distribution of habitable exo-Earth environments. We first review the qualities that define a habitable planet/moon environment. We extend these concepts to potentially habitable environments in our own Solar System and the current and future searches for biomarkers there, focusing on the primary targets for future exploratory missions: Mars, Europa, and Enceladus. We examine our current knowledge on the types of planetary systems amenable to the formation of habitable planets, and review the current state of searches for extra-solar habitable planets as well as expected future improvements in sensitivity and preparations for the remote detection of the signatures of life outside our Solar System.

    Activities against smoking in Switzerland are planned and evaluated by the "Swiss Interagency Council on Smoking and Health". With special regard to the particular local situation it tries to coordinate the programs of its members (private organization as well as state authorities) in accordance with a multi-step plan (information about the effects of smoking, publicity, motivation for change of behavior, support of smoking-withdrawal programs, influencing legislation). Evaluation of anti-smoking programs so far has only been fragmentary, showing some circumstantial evidence for a trend towards non-smoking. It is planned to evaluate the impact of future programs by periodical surveys of representative samples of the adult population, monitoring knowledge of the hazards of smoking, attitudes towards smoking, motivation for change of behavior as well as the actual smoking habits.

    Full Text Available Smoking is harmful for one’s health and affects many people in the world. Its consequences are high morbidity and mortality from cardio-respiratory diseases and cancer. This complex public health issue also entails high costs. In order to understand this addiction, it is necessary to find out whether its presence is an isolated habit or a part of an unhealthy behavior. Objective: to explore the relationship between smoking and some components of a lifestyle. Methodology: a cross-sectional study with 4,000 adults aiming at identifying the link between smoking and certain aspects of lifestyle such as age, gender, education, socioeconomic level, physical inactivity, eating habits, recreation and alcohol. Results: age and socioeconomic level were not found to be associated with smoking; however, gender, schooling level, alcohol consumption, physical inactivity, unhealthy eating habits, and inadequate recreation were found to be statistically and epidemiologically related to smoking. Conclusions: smoking is associated with other adverse components of an unhealthy lifestyle. Community control and health promotion activities should address this issue through comprehensive strategies aimed at modifying human behavior in order to achieve more effective results.

    Dental professionals are uniquely positioned to discourage smoking among their patients. However, little is known about the role of cultural background and attitudes towards smoking in the education of these professionals. Our study aimed to compare native Lithuanian and international dental students' smoking habits, knowledge about the harmfulness of smoking and attitudes towards smoking cessation. We conducted a cross-sectional survey of smoking and its cessation among dental students at the Lithuanian University of Health Sciences (Kaunas, Lithuania) in 2012. All Lithuanian and international dental students in each year of dental school were invited to participate in the survey during a compulsory practical class or seminar. Altogether 606 students participated in the survey with a response rate of 84.2%. Explanatory factorial analysis (EFA), multivariate Discriminant Analysis (DA) and Binary Logistic Regression (BLR) served for the statistical analyses. The percentages of occasional/current regular smokers were 41.1% and 55.7% (p = 0.068) among Lithuanian and international male students, and 22.7% and 22.9% (p = 0.776) among Lithuanian and international female students, respectively. The international dental students had a deeper knowledge of the harmfulness/addictiveness of smoking and held more positive attitudes towards smoking cessation among their patients than did the native Lithuanian dental students. The findings of the study underscored the need to properly incorporate tobacco cessation training into the curriculum of dental education. However, consideration of the cultural background of dental students in building up their capacity and competence for intervening against smoking is essential.

Methods We designed a smoking - related questionnaire according to the smoking- related materials. Cluster sampling method was applied to conduct a survey of smoking on 578 medical professionals of a hospital in Hunan in October, 2010. Results The current smoking rate of medical professionals was 19.38 %, and the rate of smoking was 33.64 % in males and 1.56 % in females. There were statistically significant differences in the smoking rates of medical staff members with different gender, age, educational backgrounds and professional titles (P<0.05). As for the smokingrelated knowledge and attitude, medical professionals knew the common hazards, such as pulmonary diseases easily resulted from smoking and passive smoking; but there were still 22.49% medical professionals knew little about the harmful effects of smoking and passive smoking on other organs. Most of the medical professionals thought that smoking was de rigueur and it could relieve the stress. Conclusions Smoking behavior is a serious problem among male medical workers, especially smoking behavior of staff members of medical institutions, which brings negative effects on the surrouling people. It is necessary to enhance the tobacco control in medical institutions and create tobacco-free environment in hospitals so as to be a role model and play a support role in the tobacco control work.%目的 探讨医务人员吸烟行为流行情况以及对吸烟的知识与态度.方法 参照有关资料自行设计调查问卷,采用整群抽样法,于2010年11月对湖南省某医院578名医务人员进行调查.结果 医务人员现在吸烟率为19.38%,其中男性吸烟率为33.64%,女性为1.56%;不同性别、年龄、文化程度与职称的医务人员吸烟率差异均有统计学意义(P<0.05).在对吸烟相关知识与态度方面,医务人员知道吸烟与

    Simple nodular goiter and Hashimoto's thyroiditis are 2 frequent nonmalignant thyroid diseases. Tobacco smoking has detrimental effects on the endocrine system and in particular on thyroid function and morphology. The objective of this cross-sectional study, involving 1800 Caucasian adults from a geographical area with mild iodine deficiency, was to evaluate the relationship between tobacco smoking, smoking cessation, and the prevalence of simple nodular goiter and Hashimoto's thyroiditis. Thyroid status was evaluated by ultrasonic exploration of the neck, measurement of FT3, FT4, TSH, antibodies against thyroid peroxidase and thyroglobulin, and urinary iodine excretion. The fine-needle aspiration biopsy of significant nodules was also performed. Smoking habits were evaluated by a specific questionnaire and the calculation of number of pack years. Both current and previous smokers showed an increased risk of simple nodular goiter compared to never smokers after adjustment for potential confounders and known goitrogen factors. Interestingly, the simple nodular goiter risk was similar for never smokers and for previous smokers declaring a time since cessation of smoking for more than 69 months. Smoking habit was not associated to an increased risk of Hashimoto's thyroiditis.Smoking appears to be an independent risk factor for simple nodular goiter but not for Hashimoto's thyroiditis in an area with mild iodine deficiency. A prolonged withdrawal of smoking dramatically reduces the risk of simple nodular goiter occurrence.

The stomach cancer is the second cause of cancer in the world with 9.9 % of all diagnosis and about 12.1 % of death cases. AIMS: Evaluate the body weight, educational achievement, basic sanitation, smoking, alcoholism and eating habit among patients with gastric cancer and a control group. METHODS: Seventy patients with gastric cancer were paired with 70 subjects without cancer. Data on the weight and height, educational attainment, basic sanitation, smoking, alcoholism and eating habits of the patients were collected from the clinical records and from interviews. RESULTS: Forty two patients were men, the mean age were 60 years old. The actual weight and body mass index of the patients were smaller when compared to the controls. Within the group of patients with gastric cancer, 21 never attended school, and for those who attended, 55% did not finish the elementary school. Among the patient group, 32.9% of them lived in housing with basic sanitation and 37.1% with electricity, against 68.6% of the controls, and 58.6% of the patients lived in rural area, against only 7.1% of the controls. Among the test group, 65.7% of the patients were smokers, whereas in the control group, 44.3% were smokers. In addition, there was also difference in the duration of smoking habit. Alcoholism was also more frequent in the cancer group (44% vs 19%. Food

    The Habitable Zone Gallery (www.hzgallery.org) is a new service to the exoplanet community which provides Habitable Zone (HZ) information for each of the exoplanetary systems with known planetary orbital parameters. The service includes a sortable table with information on the percentage of orbital phase spent within the HZ, planetary effective temperatures, and other basic planetary properties. In addition to the table, we also plot the period and eccentricity of the planets with respect to their time spent in the HZ. The service includes a gallery of known systems which plot the orbits and the location of the HZ with respect to those orbits. Also provided are animations which aid in orbit visualization and provide the changing effective temperature for those planets in eccentric orbits. Here we describe the science motivation, the under-lying calculations, and the structure of the web site.

    The search for life outside of the Solar System should not be restricted to exclusively planetary bodies; large moons of extrasolar planets may also be common habitable environments throughout the Galaxy. Extrasolar moons, or exomoons, may be detected through transit timing effects induced onto the host planet as a result of mutual gravitational interaction. In particular, transit timing variations (TTV) and transit duration variations (TDV) are predicted to produce a unique exomoon signature, which is not only easily distinguished from other gravitational perturbations, but also provides both the period and mass of an exomoon. Using these timing effects, photometry greater or equal to that of the Kepler Mission is readily able to detect habitable-zone exomoons down to 0.2 Earth masses and could survey up to 25,000 stars for 1 Earth-mass satellites. We discuss future possibilities for spectral retrieval of such bodies and show that transmission spectroscopy with JWST should be able to detect molecular species...

A total of 166 responders were male (44.5% and 207 responders were female (55.5% out of 373 participants. Of the 373 students, 94 (25.2% were current smokers and the average age for beginning smoking was 18.03 ± 2.6 (min: 12–max: 30. In this study, we found that the smoking prevalence associated with some variables such as age place of residence, mother’s education, father’s education, cigarette or tobacco use in the living place, knowledge status of students about their teacher’s smoking habits and alcohol consumption (p ≤ 0.05. These findings suggest that the students, who will train the sportspeople of the future, and should be considered a role model of healthy behavior in society. Consequently, we believe that sports school students should take an active role in providing health education programs to increase their awareness about the detrimental effects of smoking and to extensively quit smoking in public.

  14. Effective Physics Study Habits

    We discuss the methods of efficient study habits and how they can be used by students to help them improve learning physics. In particular, we deal with ideas pertaining to the most effective techniques needed to help students improve their physics study skills. These ideas were developed as part of Project IMPACTSEED (IMproving Physics And Chemistry Teaching in SEcondary Education), an outreach grant funded by the Alabama Commission on Higher Education. This project is motivated by a major pressing local need: A large number of high school physics teachers teach out of field. In the presentation, focus on topics such as the skills of how to develop long term memory, how to improve concentration power, how to take class notes, how to prepare for and take exams, how to study scientific subjects such as physics. We argue that the student who conscientiously uses the methods of efficient study habits will be able to achieve higher results than the student who does not; moreover, a student equipped with the proper study skills will spend much less time to learn a subject than a student who has no good study habits. The underlying issue here is not the quantity of time allocated to the study efforts by the student, but the efficiency and quality of actions. This work is supported by the Alabama Commission on Higher Education as part of IMPACTSEED grant.

    It was the aim of the present study to investigate the influence of personal characteristics, like gestational age, birth weight, maternal age, smoking habits of the parents, and geographic origin, on the neonatal pollution with these harmful substances. Methods: Cord blood samples were taken from 200 full-term, healthy neonates born in Fulda or Duesseldorf, respectively, in 1998. The samples were immediately centrifuged, and serum was stored at-20 C up to analysis, which was performed in 1999. The parents must have lived life-long in each town and should never accidentally or at their working places have been exposed to high concentrations of PCBs or HCB. Six PCB congeners (28, 52, 101, 138, 153, and 180) and HCB were analysed with capillary gas-chromatography with electron capture detection. Results: We could demonstrate a statistically significant correlation between the prenatal uptake of PCBs and HCB and the gestational age of the newborns as well as the maternal age in the study group of 199 newborns (one child was excluded because of unusually high PCB values). Thereby, neonates born in the 42. week had 3.5-fold higher PCB values than children born in the 38. week, and newborns of a 50-year-old mother showed up to 500% higher values than children of a 20-year-old woman (p < 0.0001). A correlation with birth weight was not found. Furthermore, newborns of active smoking women exhibited significantly higher PCB and HCB values than children of passive smoking or non-smoking mothers. Prenatal uptake of PCBs was not different with regard to the geographic origin of the newborns, i.e. Fulda or Duesseldorf, whereas newborns from Duesseldorf showed about 62% higher HCB concentrations.

    Diet and nutritional status have been shown to play pivotal roles in the occurrence of many chronic diseases. In this study, we examined the patterns of dietary habits and their relationships with risk factors for cardiovascular and chronic diseases in Hong Kong working populations. In April 2000, a 5-year territory-wide health promotion campaign supported by the Li Ka Shing Foundation was launched in Hong Kong by the Health InfoWorld of Hospital Authority. Between July 2000 and March 2002, 4841 Chinese subjects [2375 (49.1%) men and 2466 (50.9%) women, mean age: 42.4 +/- 8.9 years (median: 43.0 years, range: 17-83 years)] from the general working class were recruited. Subjects were randomly selected using computer generated codes according to the distribution of occupational groups. A dietary questionnaire was used to assess 6 core dietary habits: daily fruit intake, vegetable intake, fluid intake, sugary drinks, regularity of daily meals and number of dining out each day. Overall, men had a worse cardiovascular risk profile and less desirable dietary habits than women. Those who had more unhealthy dietary habits were more likely to be obese and current smokers. Using logistic regression analysis with the dietary habits as independent variables, we found that obesity, smoking and constipation were independently associated with various unhealthy dietary patterns. In conclusion, there were close associations between dietary habits and risk factors for cardiovascular diseases in Hong Kong. More effective community education about healthy lifestyle is required in Hong Kong.

    This study examined the relationships among smoking status and total and specific types of food cravings (i.e., high-fats, sweets, fast-food fats, and complex carbohydrates/starches) and the influence of demographic, clinical, and psychological factors on this relationship. Seven-hundred and twelve adults completed measures of food cravings, dietary intake, and smoking history. Heights and weights were measured. Data were analyzed using univariate and multivariate analyses while adjusting for demographic, clinical, and psychological covariates. Compared to never smokers, current smokers reported more frequent cravings for high-fat foods and fast-food fats, after controlling for depression, stress, BMI and demographic factors. Current smokers also reported consuming more high-fat foods and fast-food fats. The association between cigarette smoking and total food craving was no longer significant after accounting for depression and stress, suggesting that depression and stress may account for the relationship between smoking and total food craving. Smoking did not moderate the relationship between food cravings and food intake. Nicotine dependence was positively correlated with the frequency of general food cravings and cravings for high fats, sweets, and carbohydrates/starches. Cigarette smokers, and especially those with higher nicotine dependence, may have greater difficulties in addressing food craving and changing eating habits, particularly in the context of depression and stress.

    There is little data concerning the prevalence of smoking in the population of people with epilepsy. The present study addresses this aspect in a sample of 429 unselected adults with epilepsy living in French-speaking Switzerland. The criterion of at least one cigarette per day for the past 6 months was used to define the status of "current" smoker. The questionnaires included questions about the type of epilepsy and tobacco consumption and were prospectively filled by attending neurologists in the presence of their patient, ensuring a reliable diagnosis of epilepsy. Data were compared with those of the "Tabakmonitoring" data collection, which gives annually detailed information about tobacco use habits in the Switzerland's population according to the different linguistic regions. Among patients suffering from epilepsy, the prevalence of current smoking was 32.1 % (28.8 % among women and 35 % among men), while the prevalence of smoking was 19.0 % in the general population in French-speaking Switzerland in the same period [OR 2.0, confidence interval (CI) 1.6-2.5, p < 0.001]. The subgroup of patients with epilepsy suffering from idiopathic (genetic) generalized epilepsy had the highest prevalence of smoking: 44.3 versus 27.8 % in the other types of epilepsy-p = 0.03. Epilepsy appears significantly correlated to smoking. The possible causal relationship, such as common genetic susceptibility to epilepsy and to nicotine addiction, indirect comorbidity through stress or depression associated with epilepsy, beneficial effect of nicotine on epilepsy, still remains unclear and deserves further studies.

    Objectives: Reverse smoking is a peculiar form of smoking in which the smoker puts the lit end of the cigarette into the mouth and then inhales the smoke. There may be many predisposing factors that influence an individual to cultivate this habit, of which psychosocial habits could be the predominating factor. Hence, the present study was undertaken to evaluate the psychosocial factors that influence an individual to undertake this peculiar habit of reverse smoking. Materials and Methods: A total of 128 habitual reverse smokers were included in the study, out of which 121 were females and 7 were males. A pretested open-ended questionnaire was used for data collection. Data was collected by direct interview method. Snowball sampling technique was employed in collecting the information regarding regular reverse smokers. Interviews were continued until new information did not provide further insights into the categories. The people who could not understand verbal commands and questions and who did not give an informed consent were excluded from the study. Statistical analysis was done using MS Office Excel using Chi-square test of Goodness of fit. Results: In contrast to the conventional smokers, various new reasons were identified for starting reverse smoking, of which the most important was that they had learned this habit from their mothers. This was followed by other reasons such as peer pressure, friendship, and cold climatic conditions. Conclusion: This study provided an insight into the various factors that could influence an individual to take up this peculiar habit of reverse smoking. PMID:28032044

    This report documents the results of the Habitable Volume Workshop held April 18-21, 2011 in Houston, TX at the Center for Advanced Space Studies-Universities Space Research Association. The workshop was convened by NASA to examine the factors that feed into understanding minimum habitable volume requirements for long duration space missions. While there have been confinement studies and analogs that have provided the basis for the guidance found in current habitability standards, determining the adequacy of the volume for future long duration exploration missions is a more complicated endeavor. It was determined that an improved understanding of the relationship between behavioral and psychosocial stressors, available habitable and net habitable volume, and interior layouts was needed to judge the adequacy of long duration habitat designs. The workshop brought together a multi-disciplinary group of experts from the medical and behavioral sciences, spaceflight, human habitability disciplines and design professionals. These subject matter experts identified the most salient design-related stressors anticipated for a long duration exploration mission. The selected stressors were based on scientific evidence, as well as personal experiences from spaceflight and analogs. They were organized into eight major categories: allocation of space; workspace; general and individual control of environment; sensory deprivation; social monotony; crew composition; physical and medical issues; and contingency readiness. Mitigation strategies for the identified stressors and their subsequent impact to habitat design were identified. Recommendations for future research to address the stressors and mitigating design impacts are presented.

    Full Text Available Objective: Mounting evidence suggests a putative link between overuse of digital media and easily accessible drugs such as alcohol and nicotine. Method: We assessed Internet addiction tendencies in a sample of N=1,362 male players of online first-person-shooter-video games. We used Young’s 20-item Internet addiction test (IAT. We also asked participants about their smoking status and alcohol consumption. Results: No significant differences were observed on the IAT between smokers, non-smokers and ex-smokers. However, in line with the majority of the literature, the results yielded support for a link between Internet addiction and alcohol consumption. Of importance, this correlation was influenced by the current smoking status. This relationship was especially pronounced for the group of ex-smokers. Conclusions: It is possible that after quitting smoking, drinking habits and online activities may be used to compensate for nicotine abstinence.

    one session was performed in 28.5% of the smokers. 13% of the smokers have quit smoking, 23% have reduced smoking and 63% did not change smoking habits positively 6 months after the first visit. Conclusions: Prevalence rates for smoking in HIV+ subjects are higher than in the general population. Readiness to quit is, however, high, and 13% of smokers who have quit smoking after six months is a remarkable short-term success. This observation underlines the importance and feasibility of addressing smoking habits in HIV care.

    This report describes the Computer Codes for Evaluation of Control Room Habitability (HABIT). HABIT is a package of computer codes designed to be used for the evaluation of control room habitability in the event of an accidental release of toxic chemicals or radioactive materials. Given information about the design of a nuclear power plant, a scenario for the release of toxic chemicals or radionuclides, and information about the air flows and protection systems of the control room, HABIT can be used to estimate the chemical exposure or radiological dose to control room personnel. HABIT is an integrated package of several programs that previously needed to be run separately and required considerable user intervention. This report discusses the theoretical basis and physical assumptions made by each of the modules in HABIT and gives detailed information about the data entry windows. Sample runs are given for each of the modules. A brief section of programming notes is included. A set of computer disks will accompany this report if the report is ordered from the Energy Science and Technology Software Center. The disks contain the files needed to run HABIT on a personal computer running DOS. Source codes for the various HABIT routines are on the disks. Also included are input and output files for three demonstration runs.

    Full Text Available Abstract Background Tobacco smoking is still a worldwide health risk. Current pharmacotherapies have at best, a success rate of no more than 50%. Auricular (ear acupressure has been purported to be beneficial in achieving smoking cessation in some studies, while in others has been deemed insignificant. We hereby describe the protocol for a three-arm randomised controlled trial to examine the possible benefits of self-administered acupressure for smoking cessation. Methods Sixty consenting participants with confirmed habit of tobacco smoking will be recruited and randomized into three arms to receive either auricular acupressure at five true acupoints (NADA protocol, auricular acupressure at five sham points, or no auricular acupressure at all. Participants having auricular acupressure will exert firm pressure to each acupoint bilaterally via the bead in the attached plasters whenever they feel the urge to smoke. The treatment phase will last for six weeks during which all participants will be assessed weekly to review their smoking log, state of abstinence, end-exhalation carbon monoxide levels and possible adverse effects including withdrawal reactions and stress levels. At any time, a successful quit date will be defined with continuous abstinence for the following consecutive 7 days. From then on, participants will be evaluated individually for continuous abstinence rate (CAR, end-exhalation carbon monoxide levels and adverse effects of stress and withdrawal at specified intervals up to 26 weeks. Expectancy of treatment will be assessed with a four-item Borkovec and Nau self-assessment credibility scale during and after intervention. Discussion We incorporate validated outcome measures of smoking cessation into our randomised controlled trial design with the objectives to evaluate the feasibility and possible benefits of self-administered auricular acupressure as a non-invasive alternative to pharmacotherapy for smoking cessation.

    Tobacco consumption is a major public health threat. Midwives can contribute to the reduction of tobacco use among pregnant women and young families. It can be assumed that personal smoking behaviour and knowledge of harmful effects influences counselling activities. The aim of this study was to assess smoking status, nicotine dependency and the will to change of midwifery students in german-speaking countries. Broad data on this population is not available so far. In 2010, a self-administered questionnaire survey was conducted among Austrian, German and Swiss midwifery schools. Sociodemographic characteristics, smoking habits, personal attitudes towards smoking, knowledge of cessation strategies, perceived self-efficacy and competence to counsel pregnant women regarding their smoking habits of midwifery trainees were examined. 1 126 students and 38 teaching midwives answered this questionnaire (RR=61.8%). 22.7% are daily or occasional smokers. 6.8% have to be considered as medium and heavy smokers. 98.1% consider cessation counselling for pregnant and breast-feeding women as a midwife's task, while 76.5% feel competent enough to do so. 75.5% rate cessation counselling through midwives as effective stop-smoking procedures compared to blurry knowledge on related health risks and effective stop-smoking strategies. The self-reported smoking prevalence is considerably lower than in previous studies and other populations. Knowledge of harmful effects and of effective treatment options needs improvement. Counselling competence needs to be included in a broader way in midwifery curricula.

    Tobacco advertising has been prohibited in New Zealand since 1990, and the government has set a goal of becoming a smokefree nation by 2025. However, tobacco marketing persists indirectly through smoking in motion pictures, and there is strong evidence that exposure to onscreen smoking causes young people to start smoking. We investigated the relationship between exposure to smoking in movies and youth smoking initiation among New Zealand young adults. Data from an online survey of 419 smokers and non-smokers aged 18 to 25 were used to estimate respondents' exposure to smoking occurrences in 50 randomly-selected movies from the 423 US top box office movies released between 2008 and 2012. Analyses involved calculating movie smoking exposure (MSE) for each respondent, using logistic regression to analyse the relationship between MSE and current smoking behaviour, and estimating the attributable fraction due to smoking in movies. Exposure to smoking occurrences in movies was associated with current smoking status. After allowing for the influence of family, friends and co-workers, age and rebelliousness, respondents' likelihood of smoking increased by 11% for every 100-incident increase in exposure to smoking incidents, (aOR1.11; pexposure to smoking in movies remains a potent risk factor associated with smoking among young adults, even in a progressive tobacco control setting such as New Zealand. Harmonising the age of legal tobacco purchase (18) with the age at which it is legal to view smoking in movies would support New Zealand's smokefree 2025 goal.

  17. SMEs’ Purchasing Habits

    Full Text Available Although micro companies overpower the small and medium enterprise (SME segment, generalizations are often with medium size companies, and therefore, there are many unknowns, especially when it comes to its buying behavior. Conformist studies and industry practices assume SMEs to be “normative” or “conservative” buyers; however, this hypothesis is untested. This article aims to scrutinize the reality, and proposes a unified model that rejects pre-containerization in buying behavior typologies, as well as selectiveness in terms of audience type, whether it is corporate, SME, or consumer. While replacing researchers’ perceptions with the audience’s, the model yields actual knowledge that can lead to audience’s beliefs in lieu of the opposite, which is used to mislead stakeholders. The study shows that SMEs also buy like individuals and spend in a similar way to consumers’, including not only “normative” and “conservative” but also “negligent” and “impulse” zones. From the research-implications perspective, future studies by behaviorists can explore why SMEs purchase in this way. Marketers may benefit from the finding that SMEs buy like individuals. In addition, SMEs may want to be conscious of their purchasing habits, and—utilizing the newly introduced “risk score” frontier—policymakers should assess the consequences of these habits at the macro level.

    Binaries could provide the best niches for life in the galaxy. Though counterintuitive, this assertion follows directly from stellar tidal interaction theory and the evolution of lower mass stars. There is strong evidence that chromospheric activity of rapidly rotating young stars may be high enough to cause mass loss from atmospheres of potentially habitable planets. The removal of atmospheric water is most critical. Tidal breaking in binaries could help reduce magnetic dynamo action and thereby chromospheric activity in favor of life. We call this the Binary Habitability Mechanism (BHM), that we suggest allows for water retention at levels comparable to or better than Earth. We discuss novel advantages that life may exploit, in these cases, and suggest that life may even thrive on some circumbinary planets. We find that while many binaries do not benefit from BHM, high quality niches do exist for various combinations of stars between 0.55 and 1.0 solar masses. For a given pair of stellar masses, BHM operate...

    A notional space telescope configuration is presented that addresses issues of angular resolution, spectral bandwidth and rejection of host star glare by means of a double dispersion architecture. The telescope resolves angle by wavelength. In an earlier embodiment for surveys, a primary objective grating telescope architecture was shown to acquire millions of objects in one observation cycle, one wave length at a time. The proposed HPF can detect exquisite spectral signatures out of millions of wavelengths in albedos - one exoplanetary system at a time. Like its predecessor, the new HPF telescope has a ribbon-shaped flat gossamer membrane primary objective that lends itself to space deployment, but the preferred embodiment uses a holographic optical element rather than a plane grating. The HOE provides an improvement in efficiency at select wavelength bands. The considerable length of the membrane can be in the 100 meter class providing angular resolution sufficient to resolve planets in the habitable zone and also spectral resolution sufficient to earmark habitability. A novel interferometric secondary spectrograph rejects host star glare. However, the architecture cannot disambiguate multiple stellar sources and may require unprecedented focal lengths in the primary objective to isolate one system at a time.

    Cigarette smoking is a risk factor for earlier menopause. Animal studies show that in-utero smoke exposure is toxic to developing ovaries. Our aim was to evaluate whether in-utero smoke exposed women reach menopause earlier compared with nonexposed women. This is a cohort study within the Avon Longitudinal Study of Parents and Children. Participants included in this study were followed from 1991/1992 until 2010. Participant characteristics for the current analysis were obtained from obstetric records and from annual follow-up questionnaires. When not available, age at natural menopause was estimated by age at filling in the questionnaire minus 1 year. Cox proportional hazards modeling was used to estimate hazard ratios of menopause for in-utero exposed and nonexposed women. There were 695/2,852 postmenopausal women, of whom 466 had natural menopause, 117 had hormonal therapy, and 112 had surgical menopause. Age at natural menopause was 50.6 ± 3.7 years. Of all participants, 20.2% (577/2,852) were exposed to smoke in-utero. Participants who were in-utero exposed but were not smokers did not have higher hazards of menopause (adjusted hazard ratio [HR] 0.92, 95% CI 0.72-1.18), whereas participants who were ever smokers (current or previous) and were in-utero exposed (adjusted HR 1.41, 95% CI 1.01-1.95) or were ever smokers but not exposed (adjusted HR 1.24, 95% CI 1.00-1.53) did have higher hazards of earlier menopause. In-utero smoke exposure was not associated with earlier menopause, but the effect of in-utero smoke exposure was modified by the smoking habits of the participants themselves increasing the risk for smokers who were in-utero exposed.

    Full Text Available Abstract Background About 1.3 billion people are regular smokers world wide and every day between 8,200 and 9,900 young people start to smoke, risking rapid addiction to nicotine. Transition from high school to college is a critical period to adopt healthy habits and life style. Therefore, it is important to understand the factors that might influence their smoking habit. Our study aims to assess the influence of factors that encourage college students to smoke cigarettes. Methods The data used in this survey were obtained from a representative sample of registered colleges of Karachi. A random sample of 576 male college students of ages ranging from 15–30 years was interviewed using a questionnaire administered by survey officers, by applying multi stage cluster sampling during the academic year 2004–2005. Results In this study, we found 26.7% of students had ever tried smoking, whereas 24%(95% CI: 21.0%–28.0% of college students reported current smoking (that is whether one had smoked a cigarette in past 30 days. Among different age groups, prevalence of current smoking was 19.2% in 15–17 years, 26.5% in 18–20 years and 65% in 21 years and above. After adjusting for age of respondent, students in public schools were more likely to smoke as compared to students in private schools (adjusted OR = 2.3; 95% CI: 1.3–4.2. Students whose friends are smokers were 5 times more likely to smoke compared to those whose friends are non-smokers (adjusted OR = 4.8; 95%CI: 3.1 – 7.4. Those students having fathers with no formal schooling were more likely to smoke (adjusted OR = 2.2; 95% CI: 1.1–4.2 as compared to those whose fathers had some degree of education. Students having non-working mothers were more likely to smoke as compared to students with working mothers (adjusted OR = 2.8; 95% CI: 0.9–9.1.

    Cigarette smoking is a serious risk factor for cancer, cardiovascular, and pulmonary diseases. Current methods of monitoring of cigarette smoking habits rely on various forms of self-report that are prone to errors and under reporting. This paper presents a first step in the development of a methodology for accurate and objective assessment of smoking using noninvasive wearable sensors (Personal Automatic Cigarette Tracker-PACT) by demonstrating feasibility of automatic recognition of smoke inhalations from signals arising from continuous monitoring of breathing and hand-to-mouth gestures by support vector machine classifiers. The performance of subject-dependent (individually calibrated) models was compared to performance of subject-independent (group) classification models. The models were trained and validated on a dataset collected from 20 subjects performing 12 different activities representative of everyday living (total duration 19.5 h or 21,411 breath cycles). Precision and recall were used as the accuracy metrics. Group models obtained 87% and 80% of average precision and recall, respectively. Individual models resulted in 90% of average precision and recall, indicating a significant presence of individual traits in signal patterns. These results suggest the feasibility of monitoring cigarette smoking by means of a wearable and noninvasive sensor system in free living conditions.

  3. Smoking and women: tragedy of the majority.

    An increasing number of women are becoming victims of their smoking habit. A broader cross-section of women, other than the very rich and the "indecent," began to smoke in the 1920s, and over the past 50 years tobacco advertising has linked smoking with women's emancipation and achievement of equality with men. The marketing efforts directed to women include special packaging for feminine appeal, "designer" cigarettes, and offering discounted women's products with the purchase of a particular brand of cigarettes. Sponsorship of sporting events coupled with sports themes in cigarette advertisements associates smoking with enhanced physical capacity--a deception. The marketing experts promote smoking as a way of remaining slim in a culture obsessed with thinness. The woman who smokes today is a heavier smoker, on average, with the percentage of women smoking more than 25 cigarettes/day almost doubling from 13% in 1965 to 23% in 1985. Women start smoking at younger and younger ages. 84% of women smokers who are now 28-37 years began to smoke before age 20 as compared with 42% of those now 58-67 years. Today more young women than young men smoke. In addition to the risk of lung cancer, women who smoke also have sex-specific risks, such as those pertaining to a women's reproductive organs and processes. When smoking is of long duration, it appears to increase the risks of intraepithelial neoplasia of the cervix and of invasive cervical cancer. An antiestrogen effect of smoking may provide the explanation for why smoking women reach menopause 1-2 years earlier than nonsmokers. The same mechanism, which has been supported by several case-control studies, may increase postmenopausal osteoporotic fractures, particularly among nonobese women. Possibly the worst consequences of smoking by women are its effects on reproduction and on children. Both a dose-response depressant effect of smoking on fetal development and birth weight have been confirmed. Smoking also reduces

    Among the currently known Kepler circumbinary planets, three, namely Kepler-453b, Kepler-16b, and Kepler-47c are in the binary habitable zone (HZ). Given the large sizes of these planets, it is unlikely that they would be habitable. However, similar to the giant planets in our solar system, these planets may have large moons, which orbit their host planets while in the HZ. These exomoons, if exist, present viable candidates for habitability. As a condition for habitability, the planet-moon system has to maintain its orbital stability for long time. Usually, the empirical formula by Holeman & Wiegert (1999) is used as a measure of orbital stability in circumbinary systems. However, this formula was obtained by assuming planets to be test particles and therefore does not include possible perturbation of the planet on the binary. In this work, we present results of more realistic calculations of stability of circumbinary planets where the interactions between planets and their central binaries are taken into account. We map the region of stability, which in this case will be specific to each system, and determine the range of the orbital parameters of the moons for which their orbits will be long-term stable.

    What can we tell about exoplanet habitability if currently only the stellar properties, planet radius, and the incoming stellar flux are known? A planet is in the Habitable Zone (HZ) if it harbors liquid water on its surface. The HZ is traditionally conceived as a sharp region around stars because it is calculated for one planet with specific properties. Such an approach is limiting because the planets' atmospheric and geophysical properties, which influence the presence of liquid water on the surface, are currently unknown but expected to be diverse. A statistical HZ description is outlined which does not favor one planet type. Instead the stellar and planet properties are treated as random variables and a continuous range of planet scenarios are considered. Various probability density functions are assigned to each random variable, and a combination of Monte Carlo sampling and climate modeling is used to generate synthetic exoplanet populations with known surface climates. Then, the properties of the liquid...

    Based on calls for innovative ways of reducing car traffic and research indicating that car driving is often the result of habitual decision-making and choice processes, this paper reports on a field experiment designed to test a tool aimed to entice drivers to skip the habitual choice of the car...... and consider using-or at least trying-public transport instead. About 1,000 car drivers participated in the experiment either as experimental subjects, receiving a free one-month travelcard, or as control subjects. As predicted, the intervention had a significant impact on drivers' use of public transport...... and it also neutralized the impact of car driving habits on mode choice. However, in the longer run (i.e., four months after the experiment) experimental subjects did not use public transport more than control subjects. Hence, it seems that although many car drivers choose travel mode habitually, their final...

  19. The evolution of galaxy habitability

    Gobat, R

    2016-01-01

    We combine a semi-analytic model of galaxy evolution with constraints on circumstellar habitable zones and the distribution of terrestrial planets to probe the suitability of galaxies of different mass and type to host habitable planets, as well as its evolution with time. We find that the fraction of stars with terrestrial planets in their habitable zone ("habitability") depends only weakly on galaxy mass, with a maximum around 4e10 Msun. We estimate that 0.7% of all stars in Milky Way type galaxies to host a terrestrial planet within their habitable zone, consistent with the value derived from Kepler observations. On the other hand, the habitability of passive galaxies is slightly but systematically higher, unless we assume an unrealistically high sensitivity of planets to supernovae. We find that the overall habitability of galaxies has not changed significantly in the last ~8 Gyr, with most of the habitable planets in local disk galaxies having formed ~1.5 Gyr before our own solar system. Finally, we expe...

    With the discovery of hundreds of exoplanets and a potentially huge number of Earth-like planets waiting to be discovered, the conditions for their habitability have become a focal point in exoplanetary research. The classical picture of habitable zones primarily relies on the stellar flux allowing liquid water to exist on the surface of an Earth-like planet with a suitable atmosphere. However, numerous further stellar and planetary properties constrain habitability. Apart from "geophysical" processes depending on the internal structure and composition of a planet, a complex array of astrophysical factors additionally determine habitability. Among these, variable stellar UV, EUV, and X-ray radiation, stellar and interplanetary magnetic fields, ionized winds, and energetic particles control the constitution of upper planetary atmospheres and their physical and chemical evolution. Short- and long-term stellar variability necessitates full time-dependent studies to understand planetary habitability at any point ...

    2017-05-25

    The aim of this article is to provide clarity of the concept of health habit. Using Walker and Avant's (1983; 2010) method for conducting a concept analysis, the authors identify the attributes and characteristics of health habit, its theoretical and practical application to nursing, and sample cases to further illustrate the concept. Empirical and conceptual literature was used to inform this concept analysis. Articles and one book from 1977 to 2014 were reviewed from PsycINFO, Medline, Cumulative Index to Nursing Health Literature (CINAHL), Science Direct, EBSCOhost and Web of Science. Offering a clear definition and conceptual model of health habit provide the foundation to identify/develop appropriate measures of the concept and guide further investigation of understanding the development and sustainability of healthy habits. Additional research is needed to test the conceptual relationships between health habits and outcome variables as they apply to different groups across the age continuum. © 2017 Wiley Periodicals, Inc.

  2. Portfolio Optimization under Habit Formation

    CERN Document Server

    Naryshkin, Roman

    2008-01-01

    The "standard" Merton formulation of optimal investment and consumption involves optimizing the integrated lifetime utility of consumption, suitably discounted, together with the discounted future bequest. In this formulation the utility of consumption at any given time depends only on the amount consumed at that time. However, it is both theoretically and empirically reasonable that an individuals utility of consumption would depend on past consumption history. Economists term this "Habit Formation". We introduce a new formulation of habit formation which allows non-addictive consumption patterns for a wide variety of utility specification. In this paper we construct a simple mathematical description of this habit formation and present numerical solutions. We compare the results with the standard ones and draw insights obtained from the habit formation. The consumption path tends to increase with time and be less sensitive to the market fluctuations, which perfectly reflects the existence of habit persistenc...

  3. Comparative Habitability of Transiting Exoplanets

    CERN Document Server

    Barnes, Rory; Evans, Nicole

    2015-01-01

    Exoplanet habitability is traditionally assessed by comparing a planet's semi-major axis to the location of its host star's "habitable zone," the shell around a star for which Earth-like planets can possess liquid surface water. The Kepler space telescope has discovered numerous planet candidates near the habitable zone, and many more are expected from missions such as K2, TESS and PLATO. These candidates often require significant follow-up observations for validation, so prioritizing planets for habitability from transit data has become an important aspect of the search for life in the universe. We propose a method to compare transiting planets for their potential to support life based on transit data, stellar properties and previously reported limits on planetary emitted flux. For a planet in radiative equilibrium, the emitted flux increases with eccentricity, but decreases with albedo. As these parameters are often unconstrained, there is an "eccentricity-albedo degeneracy" for the habitability of transiti...

    Full Text Available Rheumatoid arthritis (RA is a chronic inflammatory disease caused by both genetic and environmental factors. Smoking has been implicated as one of the most important extrinsic risk factors for its development and severity. Recent developments have shed light on the pathophysiology of RA in smokers, including oxidative stress, inflammation, autoantibody formation and epigenetic changes. The association of smoking and the development of RA have been demonstrated through epidemiologic studies, as well as through in vivo and animal models of RA. With increased use of biological agents in addition to standard disease-modifying antirheumatic drugs (DMARDs, there has been interest in how smoking affects drug response in RA treatment. Recent evidence suggests the response and drug survival in people treated with anti-tumour necrosis factor (anti-TNF therapy is poorer in heavy smokers, and possible immunological mechanisms for this effect are presented in the current paper.

    Full Text Available Introduction: This paper reports on the prevalence, factors and patterns of cigarette smoking among rural California American Indian (AI adults. Methods: Thirteen Indian health clinic registries formed the random household survey sampling frame (N = 457. Measures included socio-demographics, age at smoking initiation, intention to quit, smoking usage, smoking during pregnancy, health effects of smoking, suicide attempts or ideation, history of physical abuse, neglect and the role of the environment (smoking at home and at work. Statistical tests included Chi Square and Fisher’s Exact test, as well as multiple logistic regression analysis among never, former, and current smokers. Results: Findings confirm high smoking prevalence among male and female participants (44% and 37% respectively. American Indians begin smoking in early adolescence (age 14.7. Also, 65% of current smokers are less than 50% Indian blood and 76% of current smokers have no intention to quit smoking. Current and former smokers are statistically more likely to report having suicidal ideation than those who never smoked. Current smokers also report being neglected and physically abused in childhood and adolescence, are statistically more likely to smoke ½ pack or less (39% vs. 10% who smoke 1+ pack, smoke during pregnancy, and have others who smoke in the house compared with former and never smokers. Conclusion: Understanding the factors associated with smoking will help to bring about policy changes and more effective programs to address the problem of high smoking rates among American Indians.

    Since nicotine has been shown to facilitate sustained attention and control of impulsivity, impairment in these domains may influence individuals who initiate smoking for various reasons to continue to smoke cigarettes. The purpose of this study was to determine whether young women who smoke regularly but are not abstinent at the time of testing, differ in their cognitive functioning from non-smokers and whether they resemble women who smoked in the past but quit. Female undergraduate students aged 20-30 years were recruited by advertisement from institutes of higher education in the Jerusalem area. The study sample consisted of 91 current smokers (CS), 40 past smokers (PS) and 151 non-smokers (NS). 46 occasional smokers (OS) were also tested. Confounding by withdrawal state was neutralized by including only CS and OS who smoked their last cigarette less than 90 min before testing. Subjects performed a computerized neurocognitive battery, which tests the domains of attention, memory, impulsivity, planning, information processing and motor performance. Analyses were controlled for age. The results showed that CS made significantly more errors than NS on the Continuous Performance Task (CPT), Matching Familiar Figures Test (MFFT) and Tower of London (TOL) test. PS were significantly worse than NS on the MFFT and TOL test. PS did not differ significantly from CS on any test. No association was found between duration of smoking and performance. These findings suggest that a neurocognitive profile characterized by impairments in sustained attention and control of impulsivity may be one of the factors that predispose young women who initiate cigarette smoking to maintain the habit.

    Tobacco addiction involves a transition from occasional, voluntary smoking towards habitual behavior that becomes increasingly resistant to quitting. The development of smoking habits may reflect a loss of behavioral control that can be modeled in rats. This study investigated the behavioral and neural substrates of habit formation in rats exposed to either brief (10 days) or extended (47 days) intravenous (IV) nicotine self-administration training. Following training, the first cohort of rats were exposed to a nicotine devaluation treatment, which involved repeated pairings of IV nicotine with lithium injection. They were then tested for sensitivity of responding to nicotine devaluation under extinction and reinstatement conditions. The second cohort of rats received equivalent self-administration training followed by processing of brain tissue for c-Fos immunohistochemistry. After brief training, devaluation suppressed nicotine-seeking during tests of extinction and reinstatement, confirming that responding is initially sensitive to current nicotine value, and therefore, goal directed. In contrast, after extended training, devaluation had no effect on extinction or reinstatement of responding, indicating that responding had become habitual. Complementary neuroanalysis revealed that extended nicotine self-administration was associated with increased c-Fos expression in brain regions implicated in habitual control of reward seeking, including activation of the dorsolateral striatum and substantia nigra pars compacta. These findings provide evidence of direct devaluation of an IV drug reward, that nicotine self-administration is initially goal-directed but becomes habitual with extended training, and that this behavioral transition involves activation of brain areas associated with the nigrostriatal system.

Additionally, the paper reviews the Polish literature concerning comprehending and defining “quality of life”, especially in medical sciences. Meta-analysis was a research method. Descriptions of research findings were divided into two parts: using SF-36 questionnaire (the Short Form 36 Health Survey Questionnaire and using other questionnaires. From the review of scientific research results that tobacco smoking doesn’t influence health related quality of life in an unequivocal manner. Most of the studies showed better assessment of quality of life in non-smokers than in smokers. Improved quality of life was observed among those, who gave up smoking compared to those who continued smoking, but not all researchers demonstrated such a relationship. Research concerning influence of passive smoking on quality of life in individuals inhaling tobacco smoke for example at home, work or in places to eat wasn’t carried out so far. There is a need to do more longitudinal research on quality of life in smokers, passive smokers and among those, who successfully broke the habit to better understand the role of smoking in subjective perceived quality of life.

    Observed patterns of youthful drinking indicate substantial persistence. This paper analyzes how much of that persistence reflects the actual development of a habit, and how much is due to unobserved aspects of the individual and the environment. The role of restrictions on alcohol availability, both in the current period and in adolescence, is also explored. We find that much of the observed persistence represents habit formation, and not unobserved characteristics. Consequently, restriction...

    2014-05-01

    Full Text Available Curiosity is commonly referred to as a way of being, or an object of curiosity. How curiosity is part of our daily lives, how we engage with curiosity intellectually has a long and interesting history. Since the sixteenth century it has been manifest in cabinets of curiosity, museums and curio cabinets; exercises in collecting, self-reflection and discovery. However, the end of the twentieth-century has altered our sense of the world, through the speed and accessibility of information leaving a changed relationship with wonder. This paper discusses the role of curiosity in research as a “habit of curiosity”, (Benedict 2001, 2 a method for discovery. It reviews its historical manifestations and concerns, locating it through objects and actions, and questions what new meanings the twenty-first century brings with it. Is curiosity at risk? Is it still risky? The relationship between the individual and their interior and exterior socio-cultural landscape continually creates new meanings for knowledge and how we achieve it. This shadowy landscape of our curiosity has not lost meaning intellectually, but it in our shrinking, globalized world how we engage with it requires a new investigation.

  16. Effect of Exposure to Smoking in Movies on Young Adult Smoking in New Zealand.

    Directory of Open Access Journals (Sweden)

    Philip Gendall

    Full Text Available Tobacco advertising has been prohibited in New Zealand since 1990, and the government has set a goal of becoming a smokefree nation by 2025. However, tobacco marketing persists indirectly through smoking in motion pictures, and there is strong evidence that exposure to onscreen smoking causes young people to start smoking. We investigated the relationship between exposure to smoking in movies and youth smoking initiation among New Zealand young adults. Data from an online survey of 419 smokers and non-smokers aged 18 to 25 were used to estimate respondents' exposure to smoking occurrences in 50 randomly-selected movies from the 423 US top box office movies released between 2008 and 2012. Analyses involved calculating movie smoking exposure (MSE for each respondent, using logistic regression to analyse the relationship between MSE and current smoking behaviour, and estimating the attributable fraction due to smoking in movies.Exposure to smoking occurrences in movies was associated with current smoking status. After allowing for the influence of family, friends and co-workers, age and rebelliousness, respondents' likelihood of smoking increased by 11% for every 100-incident increase in exposure to smoking incidents, (aOR1.11; p< .05. The estimated attributable fraction due to smoking in movies was 54%; this risk could be substantially reduced by eliminating smoking from movies currently rated as appropriate for youth. We conclude that exposure to smoking in movies remains a potent risk factor associated with smoking among young adults, even in a progressive tobacco control setting such as New Zealand. Harmonising the age of legal tobacco purchase (18 with the age at which it is legal to view smoking in movies would support New Zealand's smokefree 2025 goal.

    Oral habits have been described by psychologists and psychyatrists as psychodynamic phenomena. Dentists are concerned with oral habits because of the detrimental consequences they have in the oral facial system. The dentist who is in a position to confront a child with an oral habit in order to treat his dentinofacial problems is required to be aware of the psychological background of his patient as well as of the conditions under which the children do the habit in order to overcome emotional difficulties. The dentist should also search into the child's family to find out what the causes of the child's oral habit maybe. For the treatment of an oral habit the dentist should ensure both the child's and the family's cooperation and he should be aware of the advantages and disadvantages of every available method for treatment. Methods of treatment are: Use of orthodontic appliances: This method has the disadvantage that disturbs the child's psychological need for the habit, it can be interpreted as a punishment, it is visible and it causes speaking difficulties. It should be applied only in cooperation with the child. Behavioristic technique: This method aims to reinforce the child's positive behavior according to the Skinnerian principle: stimulus-response-reward. It has fast results but it is a conditioned treatment. Psychoanalytic method: It could solve the problem of the child's primary need for the oral habit in a radical manner. However it is practically impossible to be applied in Dentistry. Behavior modification according to ego psychology. With this method we attempt to analyse and understand the psychological cause of an oral habit.(ABSTRACT TRUNCATED AT 250 WORDS)

    The diversity and quantity of moons in the Solar System suggest a manifold population of natural satellites exist around extrasolar planets. Of peculiar interest from an astrobiological perspective, the number of sizable moons in the stellar habitable zones may outnumber planets in these circumstellar regions. With technological and theoretical methods now allowing for the detection of sub-Earth-sized extrasolar planets, the first detection of an extrasolar moon appears feasible. In this review, we summarize formation channels of massive exomoons that are potentially detectable with current or near-future instruments. We discuss the orbital effects that govern exomoon evolution, we present a framework to characterize an exomoon's stellar plus planetary illumination as well as its tidal heating, and we address the techniques that have been proposed to search for exomoons. Most notably, we show that natural satellites in the range of 0.1 - 0.5 Earth mass (i) are potentially habitable, (ii) can form within the c...

    We review how tides may impact the habitability of terrestrial-like planets. If such planets form around low-mass stars, then planets in the circumstellar habitable zone will be close enough to their host stars to experience strong tidal forces. We discuss 1) decay of semi-major axis, 2) circularization of eccentric orbits, 3) evolution toward zero obliquity, 4) fixed rotation rates (not necessarily synchronous), and 5) internal heating. We briefly describe these effects using the example of a 0.25 solar mass star with a 10 Earth-mass companion. We suggest that the concept of a habitable zone should be modified to include the effects of tides.

    The purpose of this study was to compare the dietary habits, nutrient intake, bone mineral density (BMD) and bone metabolism in Korean male collegians as related to smoking situation. One hundred sixty one young adult males at the age of 20-26 participated in this study. The subjects were divided into four groups: non smoker (n=42), light smoker (n=34), moderate smoker (n=49) and heavy smoker (n=36). The anthropometric characteristics, smoking situations, dietary habits and nutrient intakes were observed. Bone status of the calcaneus was measured by using quantitative ultrasound (QUS). Bone metabolism markers including serum alkaline phosphatase activity (ALP) and N-mid osteocalcin (OC) were analyzed. There were no significant differences in height, weight, BMI, energy and calcium intake among the four groups. Iron intake of moderate and heavy smoker was significantly lower than that of light smoker. Heavy smokers consumed significantly lower vitamin C than moderate smokers, and their coffee consumption and lifetime alcohol consumption were significantly highest among the 4 groups. QUS parameters and serum ALP were not significantly different among the four groups. Serum OC levels were significantly lower in heavy and non smoker group compared to the moderate smoker group. In conclusion, heavy smokers in young male collegians had undesirable lifestyle and dietary habits, like as high consumption of coffee and alcohol, and low intake of Fe and vitamin C. Although, there was no significant difference in their current bone status from the other groups, these undesirable factors with heavy smoking may affect their bone health in the long term.

    The aim of the study was to analyze the teachers attitudes towards smoke-free regulations in public places. The study population consisted of 348 teachers. Among the study participants the questionnaire was conducted including socio-demographic characteristic and smoking profile. Detailed information was collected about teachers' opinion on smoke-free public places. About 13% of study participants declared current daily tobacco smoking and 5% smoked occasionally. Almost all study participants (90%-93%) are in favor of smoking ban in offices, health and educational buildings and sport facilities. 83% supported smoking ban in workplaces. Most of the teachers were in favor of smoke-free restaurants (71%) but they were less likely to support smoke-free bars, pubs and clubs (55%). The percentage of teachers who supported total ban on smoking in the presence of pregnant women was 94% and in the presence of children 93%. About 27%of the study subjects did not accept the concept of raising taxes on tobacco. Total ban on tobacco advertising was accepted by 70% of teachers and support for pictorial warning on tobacco packages declared 75% of participants. About 45% of study population indicated that they noted other teachers smoked at school (where smoking is banned). For students such percentages were even higher (76%). It is important to strengthen educational and informational activities to increase public awareness on health consequences of active and passive smoking and the ways of elimination of such exposures.

    For many years has been well known that smoking could cause lung damage. Chronic obstructive pulmonary disease and lung cancer have been the two most common smoking-related lung diseases. In the recent years, attention has also focused on the role of smoking in the development of interstitial lung diseases (ILDs). Indeed, there are three diseases, namely respiratory bronchiolitis-associated ILD, desquamative interstitial pneumonia and pulmonary Langerhans cell histiocytosis, that are currently considered aetiologically linked to smoking and a few others which are more likely to develop in smokers. Here, we aim to focus on the most recent findings regarding the role of smoking in the pathogenesis and clinical behaviour of ILDs.

  4. Electronic cigarettes for smoking cessation.

    Electronic cigarettes (e-cigarettes) are novel vaporising devices that, similar to nicotine replacement treatments, deliver nicotine but in lower amounts and less swiftly than tobacco smoking. However, they enjoy far greater popularity than these medications due in part to their behaviour replacement characteristics. Evidence for their efficacy as cessation aids, based on several randomised trials of now obsolete e-cigarettes, suggests a modest effect equivalent to nicotine patch. E-cigarettes are almost certainly far less harmful than tobacco smoking, but the health effects of long-term use are as yet unknown. Dual use is common and almost as harmful as usual smoking unless it leads to quitting. Population effects, such as re-normalising smoking behaviour, are a concern. Clinicians should be knowledgeable about these products. If patients who smoke are unwilling to quit or cannot succeed using evidence-based approaches, e-cigarettes may be an option to be considered after discussing the limitations of current knowledge.

    The fossil record shows that the Earth has experienced several mass extinctions over the past 500 million years1, and it has been suggested that there is a periodicity in extinction events on timescales of tens1 and/or hundreds of millions of years. Various hypotheses have been proposed to explain the cause of the mass extinctions, including the suggestion that the Earth's ozone layer may have been destroyed by intense radiation from a nearby supernovae2- 3, exposing the Earth's surface to damaging UV radiation. Recent observations of cores taken from the ocean floor revealed atoms of a very rare isotope of iron (60Fe) believed to have arrived on Earth around 2 million years ago as fallout from a nearby supernovae4. Astronomical evidence for that past supernovae was recently found in the debris of a young cluster of massive stars5, by tracing its past orbit, putting it at the right place at the right time to explain the mild extinction event. Here we report new high-resolution (both in space and time) N-body chemodynamical simulations (carried out with our novel code GCD+6) of the evolution of a model Milky Way Galaxy, tracing the orbit of èsun-like' stars over a 500 million year period, checking the proximity to supernovae throughout the history of the orbit and comparing the times when this occurs with past mass extinctions on Earth. We additionally explain the important effects of the spiral arm pattern, radial migration of stars and Galactic chemistry on habitability.

    We discuss the possibility of screening the atmosphere of exomoons for habitability. We concentrate on Earth-like satellites of extrasolar giant planets (EGP) which orbit in the Habitable Zone of their host stars. The detectability of exomoons for EGP in the Habitable Zone has recently been shown to be feasible with the Kepler Mission or equivalent photometry using transit duration observations. Using the Earth itself as a proxy we show the potential and limits of spectroscopy to detect biomarkers on an Earth-like exomoon and discuss effects of tidal locking for such potential habitats. Transmission spectroscopy of exomoons is a unique potential tool to screen them for habitability in the near future.

    Using coordination polyhedron rule, growth habit of polar crystals such as ZnO, ZnS and SiO2 is investigated. It shows that the growth rates in the positive and negative polar axis directions are different. The theoretical growth habit of ZnO crystal is hexagonal prism and the growth rates of its various faces are:V{0001}>V{0111}-->V{0110}->V{0111}->V{0001}-. The growth habit of ZnS crystal is tetrahedron and its growth rates of different crystal faces are: V{111}>V{001}>V{001} =V{100} =. The growth rate relationship between positive and negative polar axis directions of SiO2 crystal V[1120]-->V[1120]-.is These results are in agreement with the growth habits observed under hydrothermal conditions. The different growth rates between positive and negative polar axis directions cannot be explained by PBC theory.

    The collected data in Bushehr Elderly Health (BEH) Program which had detailed the data on participants' smoking status and habits, was analysed to investigate the association between smoking of both water pipes and cigarettes and hypertension in an elderly population. Three thousand elderly men and women who participated in the baseline assessment of the BEH Program-a prospective population-based study being conducted in Bushehr, Iran-were selected randomly through a multistage, stratified cluster sampling method. Systolic and diastolic blood pressures were measured twice using a mercury sphygmomanometer, and researchers asked participants about medical history of hypertension as well as history of cigarette and water pipe smoking. Researchers used binary logistic regression models to assess the association of hypertension and smoking, and found an inverse, statistically significant association between current smoking and hypertension (odds ratio (OR)=0.50 (95% confidence interval (CI)=0.41, 0.60)). The association remained statistically significant after controlling for age, education and body mass index (OR=0.54 (95% CI=0.45, 0.66)). Findings were consistent for cigarette and water pipe smoking by sex (all ORs were inverse and statistically significant). Both cigarette and water pipe smoking were associated with reduced hypertension among older people, but the strength of association was different between men and women and also between cigarette and water pipe smoking. The reasons behind the association as well as the differences observed need to be investigated through more comprehensive, longitudinal studies.Journal of Human Hypertension advance online publication, 7 September 2017; doi:10.1038/jhh.2017.64.

    Full Text Available Abstract Background Fear of weight gain is a barrier to smoking cessation and significant cause of relapse for many people. The provision of nutritional advice as part of a smoking cessation programme may assist some in smoking cessation and perhaps limit weight gain. The aim of this study was to determine the effect of a structured programme of dietary advice on weight change and food choice, in adults attempting smoking cessation. Methods Cluster randomised controlled design. Classes randomised to intervention commenced a 24-week intervention, focussed on improving food choice and minimising weight gain. Classes randomised to control received “usual care”. Results Twenty-seven classes in Greater Glasgow were randomised between January and August 2008. Analysis, including those who continued to smoke, showed that actual weight gain and percentage weight gain was similar in both groups. Examination of data for those successful at giving up smoking showed greater mean weight gain in intervention subjects (3.9 (SD 3.1 vs. 2.7 (SD 3.7 kg. Between group differences were not significant (p = 0.23, 95% CI −0.9 to 3.5. In comparison to baseline improved consumption of fruit and vegetables and breakfast cereal were reported in the intervention group. A higher percentage of control participants continued smoking (74% vs. 66%. Conclusions The intervention was not successful at minimising weight gain in comparison to control but was successful in facilitating some sustained improvements in the dietary habits of intervention participants. Improved quit rates in the intervention group suggest that continued contact with advisors may have reduced anxieties regarding weight gain and encouraged cessation despite weight gain. Research should continue in this area as evidence suggests that the negative effects of obesity could outweigh the health benefits achieved through reductions in smoking prevalence.

    The purpose of this study is to analyze the vocal behavior of flamenco singers, as compared with classical music singers, to establish a differential vocal profile of voice habits and behaviors in flamenco music. Bibliographic review was conducted, and the Singer's Vocal Habits Questionnaire, an experimental tool designed by the authors to gather data regarding hygiene behavior, drinking and smoking habits, type of practice, voice care, and symptomatology perceived in both the singing and the speaking voice, was administered. We interviewed 94 singers, divided into two groups: the flamenco experimental group (FEG, n = 48) and the classical control group (CCG, n = 46). Frequency analysis, a Likert scale, and discriminant and exploratory factor analysis were used to obtain a differential profile for each group. The FEG scored higher than the CCG in speaking voice symptomatology. The FEG scored significantly higher than the CCG in use of "inadequate vocal technique" when singing. Regarding voice habits, the FEG scored higher in "lack of practice and warm-up" and "environmental habits." A total of 92.6% of the subjects classified themselves correctly in each group. The Singer's Vocal Habits Questionnaire has proven effective in differentiating flamenco and classical singers. Flamenco singers are exposed to numerous vocal risk factors that make them more prone to vocal fatigue, mucosa dehydration, phonotrauma, and muscle stiffness than classical singers. Further research is needed in voice training in flamenco music, as a means to strengthen the voice and enable it to meet the requirements of this musical genre. Copyright © 2017 The Voice Foundation.

Of the 3,488 (98% surveyed, 26.9% were smokers (62% daily, 20.6% were ex-smokers and 52.5% non-smokers. There were differences related to age and sex (p< 0.05. Of daily smokers, 36% smoked between 1 and 5 cigarettes. There was a significant trend among ex-smokers that linked the time they had ceased smoking with the fear to start smoking again. Physicians were well informed of the relationship between cigarette smoking and lung cancer. Over 80% considered tobacco an addictive drug but only 65% were in favor of banning smoking from their workplaces and over 10% were not aware that it is forbidden to smoke inside health care facilities. Conclusions. These results differ from other studies that find the prevalence of smoking among physicians lower than in the general population. Our study revealed a greater prevalence of the smoking habit among female physicians and the number of cigarettes smoked per day was greater than in the general population regardless of sex.

    Full Text Available Abstract Background In the past year Lebanon has been experiencing a nutritional transition in food choices from the typical Mediterranean diet to the fast food pattern. As a consequence, the dietary habits of young adults have been affected; thus, overweight and obesity are increasingly being observed among the young. The purpose of this study is to assess the prevalence of overweight and obesity on a sample of students from the Lebanese American University (in Beirut and to examine their eating habits. Methods A cross-sectional survey of 220 students (43.6% male and 56.4% female, aged 20 ± 1.9 years, were chosen randomly from the Lebanese American University (LAU campus during the fall 2006 semester. Students were asked to fill out a self-reported questionnaire that included questions on their eating, drinking and smoking habits. Also, their weight, height, percentage body fat and body mass index were measured. Body mass index (BMI was used to assess students' weight status. Statistical analyses were performed using the Statistical Package for Social Sciences software (version 13.0 to determine overweight and obesity among students and to categorize eating habits. Results This study showed that the majority of the students (64.7% were of normal weight (49% male students compared to 76.8% female students. The prevalence of overweight and obesity was more common among male students compared to females (37.5% and 12.5% vs. 13.6% and 3.2%, respectively. In contrast, 6.4% female students were underweight as compared to 1% males. Eating habits of the students showed that the majority (61.4% reported taking meals regularly. Female students showed healthier eating habits compared to male students in terms of daily breakfast intake and meal frequency. 53.3% of female students reported eating breakfast daily or three to four times per week compared to 52.1% of male students. There was a significant gender difference in the frequency of meal intake (P

    Smoking among health professionals has been shown to influence smoking-related knowledge and counseling in clinical practice. The evidence regarding smoking as a risk factor has increased in the past decade. The present study was carried out in 2000 and investigated the associations between individual smoking behavior among hospital staff and (a). smoking-related knowledge, (b). attitudes toward counseling on smoking, and (c). self-reported smoking-related counseling provided by the staff. The study was based on a survey using self-administered questionnaires given to all hospital staff in a large university hospital in Denmark. Altogether, 82% of staff (2561) returned a completed questionnaire. Analyses focused on a subsample consisting of health professionals in the clinical wards (1429). Multivariate analyses were performed in which smoking-related knowledge, attitudes toward smoking-related counseling, smoking-related counseling practices, and self-rated qualifications for counseling were main outcome measures. Health professionals who were current smokers systematically underestimated the health consequences of smoking and differed significantly from nonsmokers in their assessments of smoking as a risk factor. Nonsmokers might overestimate smoking as a risk factor. Nonsmokers gave patients advice on smoking cessation significantly more often than did current smokers (ex-smokers, OR=2.5, 95% CI=1.8-3.4; never-smokers, OR=1.5, 95% CI=1.1-2.0). Ex-smokers and smokers felt significantly more qualified to counsel patients about smoking than did never-smokers (ex-smokers, OR=1.8, 95% CI=1.3-2.5; smokers, OR=1.4, 95% CI=1.0-1.9). Individual smoking behavior among hospital staff was strongly associated with smoking-related knowledge, attitudes, and counseling practices. Lack of self-rated qualifications was a major barrier to professional counseling on smoking in a hospital framework.

    We report on the current results and envisioned future work from our study of the binary star system Kepler-16, which consists of a K-type main-sequence star and an M dwarf as well as a circumbinary Saturnian planet, Kepler-16b. We focus on the calculation of the location and extent of the habitable zone while considering several criteria for both the inner and outer boundaries previously given in the literature. In particular, we investigate the impact of the two stellar components (especially Kepler-16A) as well as of the system’s binarity regarding the provision of circumbinary habitability. Another aspect of our work consists in a careful assessment of how the extent of the system’s habitable zone is impacted by the relative uncertainties of the stellar and system parameters. Finally, we comment on the likelihood of habitable objects in the system by taking into account both radiative criteria and the need of orbital stability.

    Results: Prevalence of oral mucosal lesions was found to be 8%. Smoker's palate was the most frequently found oral lesion comprising of 33.89% followed by oral lichen planus and leukoplakia (13.55% each. Other lesions included chemical burns, erythroplakia, OSMF and lichenoid reactions. Subjects were indulged into various habits; the most prevalent being the cigarette smoking (56.46%, followed by hukka and bidi smoking and smokeless tobacco. Conclusions: The prevalence of oral mucosal lesions was 8% among the study sample. Subjects were associated with various deleterious habits which were found more in males than females. This study helps in public awareness about the ill effects of oral habits and may motivate them in overcoming their indulgence. [Int J Res Med Sci 2016; 4(8.000: 3525-3530

    Self-medication models of smoking posit that the emotional benefits of smoking reinforce and maintain cigarette use, yet research demonstrates both positive and adverse affective consequences of smoking. The current study examined longitudinal changes in adolescent mood variability and overall negative mood at various stages of smoking behavior to inform understanding of the etiology of adolescent smoking. Participants included 461 adolescents (M age = 15.67 years, SD = 0.61; 55% girls, 56.8% White) drawn from a longitudinal study of adolescent smoking. Youth provided data on smoking behavior at baseline and a 15-month follow-up wave. Ecological momentary assessments were used to measure overall levels of negative mood as well as within-person mood fluctuations (i.e., negative mood variability) at each wave. Findings revealed that smoking-mood relations vary across different stages of smoking behavior. Youth who rapidly escalated in their smoking during the study experienced improved mood regulation (for girls) and improved overall mood (for boys) as smoking increased. However, mood improvements were not observed among youth with sustained heavy use and symptoms of dependence. The current data argue for a model of smoking that accounts for changes in risk and maintenance factors at different points along the developmental trajectory of smoking, involving elements of both self-medication and dependence.

  4. Habits, action sequences and reinforcement learning.

    It is now widely accepted that instrumental actions can be either goal-directed or habitual; whereas the former are rapidly acquired and regulated by their outcome, the latter are reflexive, elicited by antecedent stimuli rather than their consequences. Model-based reinforcement learning (RL) provides an elegant description of goal-directed action. Through exposure to states, actions and rewards, the agent rapidly constructs a model of the world and can choose an appropriate action based on quite abstract changes in environmental and evaluative demands. This model is powerful but has a problem explaining the development of habitual actions. To account for habits, theorists have argued that another action controller is required, called model-free RL, that does not form a model of the world but rather caches action values within states allowing a state to select an action based on its reward history rather than its consequences. Nevertheless, there are persistent problems with important predictions from the model; most notably the failure of model-free RL correctly to predict the insensitivity of habitual actions to changes in the action-reward contingency. Here, we suggest that introducing model-free RL in instrumental conditioning is unnecessary, and demonstrate that reconceptualizing habits as action sequences allows model-based RL to be applied to both goal-directed and habitual actions in a manner consistent with what real animals do. This approach has significant implications for the way habits are currently investigated and generates new experimental predictions.

    Histories of adenoïdectomy and tonsillectomy were ascertained, as well as smoking habits of both parents, using questionnaires answered by 3920 schoolchildren aged 10 to 20. Adenoïdectomy and/or tonsillectomy, considered as an index of repeated upper respiratory tract disease in early childhood, was very significantly related to the amount of smoking by each parent. This relationship persisted when age, sex, day nursery attendance, sibship size, and history of appendicectomy were controlled.

  9. The Aristotelian conception of habit and its contribution to human neuroscience

    Directory of Open Access Journals (Sweden)

    Javier eBernacer

    2014-11-01

    Full Text Available The notion of habit used in neuroscience is an inheritance from a particular theoretical origin, whose main source is William James. Thus, habits have been characterized as rigid, automatic, unconscious, and opposed to goal-directed actions. This analysis leaves unexplained several aspects of human behavior and cognition where habits are of great importance. We intend to demonstrate the utility that another philosophical conception of habit, the Aristotelian, may have for neuroscientific research. We first summarize the current notion of habit in neuroscience, its philosophical inspiration and the problems that arise from it, mostly centered on the sharp distinction between goal-directed actions and habitual behavior. We then introduce the Aristotelian view and we compare it with that of William James. For Aristotle, a habit is an acquired disposition to perform certain types of action. If this disposition involves an enhanced cognitive control of actions, it can be considered a habit-as-learning. The current view of habit in neuroscience, which lacks cognitive control and we term habit-as-routine, is also covered by the Aristotelian conception. He classifies habits into three categories: 1 theoretical, or the retention of learning understood as knowing that x is so; 2 behavioral, through which the agent achieves a rational control of emotion-permeated behavior (knowing how to behave; and 3 technical or learned skills (knowing how to make or to do. Finally, we propose new areas of research where this novel conception of habit could serve as a framework concept, from the cognitive enrichment of actions to the role of habits in pathological conditions. In all, this contribution may shed light on the understanding of habits as an important feature of human action. Habits, viewed as cognitively controlled behaviors that in turn improve cognitive control of behavior, are a crucial resource for enhancing human learning and behavioral plasticity.

  10. Comparative Habitability of Transiting Exoplanets

    Exoplanet habitability is traditionally assessed by comparing a planet’s semimajor axis to the location of its host star’s “habitable zone,” the shell around a star for which Earth-like planets can possess liquid surface water. The Kepler space telescope has discovered numerous planet candidates near the habitable zone, and many more are expected from missions such as K2, TESS, and PLATO. These candidates often require significant follow-up observations for validation, so prioritizing planets for habitability from transit data has become an important aspect of the search for life in the universe. We propose a method to compare transiting planets for their potential to support life based on transit data, stellar properties and previously reported limits on planetary emitted flux. For a planet in radiative equilibrium, the emitted flux increases with eccentricity, but decreases with albedo. As these parameters are often unconstrained, there is an “eccentricity-albedo degeneracy” for the habitability of transiting exoplanets. Our method mitigates this degeneracy, includes a penalty for large-radius planets, uses terrestrial mass-radius relationships, and, when available, constraints on eccentricity to compute a number we call the “habitability index for transiting exoplanets” that represents the relative probability that an exoplanet could support liquid surface water. We calculate it for Kepler objects of interest and find that planets that receive between 60% and 90% of the Earth’s incident radiation, assuming circular orbits, are most likely to be habitable. Finally, we make predictions for the upcoming TESS and James Webb Space Telescope missions.

    Full Text Available Abstract Background Very few studies have evaluated the adverse effect of passive smoking exposure among active smokers, probably due to the unproven assumption that the dose of toxic compounds that a smoker inhales by passive smoke is negligible compared to the dose inhaled by active smoke. Methods In a controlled situation of indoor active smoking, we compared daily benzo(apyrene (BaP dose, estimated to be inhaled by smokers due to the mainstream (MS of cigarettes they have smoked, to the measured environmental tobacco smoke (ETS they inhaled in an indoor environment. For this aim, we re-examined our previous study on daily personal exposure to BaP of thirty newsagents, according to their smoking habits. Results Daily BaP dose due to indoor environmental contamination measured inside newsstands (traffic emission and ETS produced by smoker newsagents was linearly correlated (p = 0.001 R2 = 0.62 with estimated BaP dose from MS of daily smoked cigarettes. In smoker subjects, the percentage of BaP daily dose due to ETS, in comparison to mainstream dose due to smoked cigarettes, was estimated with 95% confidence interval, between 14.6% and 23% for full flavour cigarettes and between 21% and 34% for full flavour light cigarettes. Conclusions During indoor smoking, ETS contribution to total BaP dose of the same smoker, may be not negligible. Therefore both active and passive smoking exposures should be considered in studies about health of active smokers.

  14. Predicting Electronic Failure from Smoke

    Smoke can cause electronic equipment to fail through increased leakage currents and shorts. Sandia National Laboratories is studying the increased leakage currents caused by smoke with varying characteristics. The objective is to develop models to predict the failure of electronic equipment exposed to smoke. This requires the collection of data on the conductivity of smoke and knowledge of critical electrical systems that control high-consequence operations. We have found that conductivity is a function of the type of fuel, how it is burned, and smoke density. Video recordings of highly biased dc circuits exposed in a test chamber show that during a fire, smoke is attracted to high voltages and can build fragile carbon bridges that conduct leakage currents. The movement of air breaks the bridges, so the conductivity decreases after the fire is extinguished and the test chamber is vented. During the fire, however, electronic equipment may not operate correctly, leading to problems for critical operations dependent on electronic control. The potential for electronic failure is highly dependent on the type of electrical circuit, and Sandia National Laboratories plans to include electrical circuit modeling in the failure models.

    Oral habits or parafunction may contribute to dental, periodontal, or neuromuscular damage. Such habits, of which the patient is often unaware, may cause considerable damage. Habits may be occlusal or non-occlusal, and may affect the dentition and/or the oral soft tissues. Drawing a patient's attention to the damage caused by some habits of which he or she is unaware often leads to cessation, whereas with certain conscious habits, such as nail or finger biting, success is much more limited.

    Full Text Available Background: Smoking is the most important, preventable cause of premature death and this addiction can be regarded as a chronic, recurrent disease. The benefits of smoking cessation are unquestionable and all health care professionals should become more active in recommending it. Aim: To characterise the population seeking medical support for smoking cessation and to investigate the effectiveness of a smoking cessation programme performed, in the University Hospital of Larissa, for outpatients. Materials and Methods: Retrospective analysis of medical records of outpatients in follow-up between March 2004 and October 2007. Age, gender, level of education, smoking habits, compliance in pharmacological treatment, gain weight and abstinence and relapse rates were evaluated.Results: Were studied 376 smokers, 60% male with an average age of 46.9 years. Men, upper graduated smokers have higher cessation rates whereas, in heavy smokers with high degree of dependence was observed lower cessation rates. The continuous abstinence rate at 12 months was 38%, and among pharmacological treatment, varenicline resulted elevated rate of quit smoking. The rate of relapse was found in 39%.Conclusions: This study suggests that smoking cessation programmes may be highly effective in helping smoking withdrawal and should be a strongly recommended component of daily clinical practice.

    A massive amount of research has brought out the association of daily smoking with social class. Smoking remains very common in the most disadvantaged groups, but it has also maintained its popularity among manual workers. The starting point of the article is that what needs to be taken into account in explaining the social differentiation of smoking is the social context in which smoking takes place. The study is based on interviews of daily smokers, ex-smokers and occasional smokers from different occupational backgrounds. In this article, the focus is on manual workers (N = 19), and the main interest is in the meaning of smoking in working-class contexts and how it is attached to daily routines and social settings in manual work. Theoretically, the study draws on the pragmatist idea of habits and how they are formed in accordance with the context. As a shared ritual, smoking was a self-evident part of daily routines at the workplaces under scrutiny. The study shows how smoking was a legitimate way to challenge the official rules and to make the work more bearable by increasing social contacts and a sense of belonging. Paradoxically, smoking was to a great extent an unquestioned routine, but at the same time it increased the autonomy of the workers in terms of their daily tasks.

    Full Text Available Recreational sunbed use accounts for the main non-solar source of exposure to ultraviolet radiation in fair-skinned Western populations. Indoor tanning is associated with increased risks for acute and chronic dermatological diseases. The current community-based study assessed the one-year prevalence of sunbed use and associated skin health habits among a representative, gender-balanced sample of 1500 Austrian citizens. Overall one-year prevalence of sunbed use was 8.9% (95% confidence interval (CI 7.5%–10.4%, with slightly higher prevalence in females (9.2%, 95% CI 7.3%–11.2% compared to males (8.6%, 95% CI 6.7%–10.6%. Factors predicting sunbed use were younger age (by trend decreasing with older age, place of living, smoking, skin type (by trend increasing with darker skin, sun exposure, motives to tan, and use of UV-free tanning products. Despite media campaigns on the harmful effects of excessive sunlight and sunbed exposure, we found a high prevalence of self-reported sunbed use among Austrian citizens. From a Public (Skin Health perspective, the current research extends the understanding of prevailing leisure time skin health habits in adding data on prevalence of sunbed use in the general Austrian population.

This paper is designed to search out the ways to increase the effectiveness of such campaign by analyzing the behaviour and attitudes of smoking people of Sylhet city. Primary data are collected from 268 respondents selected by stratified sampling design by a semi-structured questionnaire and secondary from different published materials for this empirical research. It is inferred that lack of awareness and seriousness about warning is the cause of smoking habit that is prevailed mostly among lower and medium income people who are struggling for their livelihood. It started from their student life when emotion and curiosity dominates over other elements in human life cycle. But at the matured stage they cannot give up the addiction habit easily till the suffering from disease started or the strong obstruction from closest family members faced. It is also inferred that strong will power to give up that habit at a time make the intended people successful in that most necessary abandoning event to save himself from active effect of smoking and others from passive effect of smoking. Social Marketing through the strong hand of Social Advertising along with other 3P’s (Product, Place & Price can play the most significant role by creating mass awareness and guiding self control in anti-smoking campaign by bringing change in social attitude.

    Full Text Available Aim: The aim was to measure the prevalence of smoking and identify its potential predictors among military personnel in Kingdom of Saudi Arabia (KSA. Materials and Methods: This cross-sectional study was carried out among military personnel in the five military regions of KSA between January 2009 and January 2011. The sample of 10,500 military personnel in the Saudi Armed Forces was equally divided among the five regions with a ratio 3:7 for officers and soldiers. A multistage stratified random sampling was used to recruit participants in the four services of the armed forces in the five regions. Information on sociodemographic characteristics with a detailed history of smoking was collected by means of a self-administered questionnaire. Bivariate analysis was used to identify the factors associated with smoking, and multiple logistic regression analysis to discover its potential predictors. Results: About 35% of the sample was current smokers, with higher rates among soldiers. The eastern region had the highest rate (43.0%, and the southern region the lowest (27.5%. Navy personnel had a higher risk of being current smokers (40.6%, and the air defense the lowest risk (31.0%. Multivariate analysis identified working in the navy, and low income as positive predictors of current smoking, while residing in the southern region, older age, years of education, being married, and having an officer rank were negative (protective factors. Conclusion: Smoking is prevalent among military personnel in KSA, with higher rates in the Navy and Air Force, among privates, younger age group, lower education and income, and divorced/widowed status. Measures should be taken to initiate programs on smoking cessation that involve changes in the environment that is likely to promote this habit.

    Full Text Available Smoking is harmful to the health of adolescents because their bodies are still growing. The aim of this study was to analyze the association between the smoking status of Korean adolescents’ parents and friends and their own smoking behavior. The study assessed a nationwide sample of 72,060 middle and high students from the 10th Korea Youth Risk Behavior Web-based Survey (2014. Descriptive analysis, chi-square tests, and multiple logistic regression analysis were used to probe the association between family and friend smoking status and adolescent smoking behavior. The current cigarette smoking rates were 13.3% of boys and 4.1% of girls. The corresponding rates for electronic cigarette smoking were 4.1% and 1.5%, respectively. Higher exposure to secondhand smoke, smoking by any family member, more friends smoking, and witnessed smoking at school were associated with current smoking and electronic smoking. The smoking status of family and friends was significantly related to adolescent smoking behavior. These results should be considered in designing programs to control adolescent smoking.

    Smoking is harmful to the health of adolescents because their bodies are still growing. The aim of this study was to analyze the association between the smoking status of Korean adolescents' parents and friends and their own smoking behavior. The study assessed a nationwide sample of 72,060 middle and high students from the 10th Korea Youth Risk Behavior Web-based Survey (2014). Descriptive analysis, chi-square tests, and multiple logistic regression analysis were used to probe the association between family and friend smoking status and adolescent smoking behavior. The current cigarette smoking rates were 13.3% of boys and 4.1% of girls. The corresponding rates for electronic cigarette smoking were 4.1% and 1.5%, respectively. Higher exposure to secondhand smoke, smoking by any family member, more friends smoking, and witnessed smoking at school were associated with current smoking and electronic smoking. The smoking status of family and friends was significantly related to adolescent smoking behavior. These results should be considered in designing programs to control adolescent smoking.

    This study aimed to determine the attitudes toward smoking and the characteristics of smoking patterns in young men of military age. Individuals performing their military service were surveyed using a self-administered, anonymous, personal and voluntary questionnaire. Questions were included on smoking habits, social context, and desire to quit. Responses were received from 386 (93.46%) subjects, all male, whose mean age was 20.52 +/- 2.3 years. The sample included 207 smokers (53.62%), 173 non smokers (44.81%) and 6 ex-smokers (1.55%). Mean age of initiation was 15.07 +/- 2.4 years and mean age of start of habitual smoking was 16.46 +/- 2.2 years. The main reasons for starting to smoke were curiosity (39.73%) and peer pressure (29.45%). Between 11 and 20 cigarettes/day were smoked by 53.74%. Those who began before 18 years of age smoked more than those who began after age 19. Light tobacco was smoked by 90.87%. Non smokers had fewer friends and family members who smoked than did smokers (p reason for increased smoking. We conclude that the prevalence of daily smoking is high among young men, who begin smoking regularly at 16 years of age. Those who begin later smoke less. The influence of friends and family members on initiation and maintenance of smoking is great. Half the smokers contemplated quitting and reported a high number of earlier attempts to stop. We believe that military quarters are an ideal place for health education and promotion, offering the possibility of designing special programs for decreasing the prevalence of smoking among adults.

    The study investigated the relationships among local smoke-free public policies, county-level quitline call rate, and adult smoking status. A retrospective cross-sectional examination of demographic characteristics, smoking status of Kentuckians, and data from the Kentucky Tobacco Quitline were used to investigate the relationship of local smoke-free ordinances or Board of Health regulations together with county-level quitline use rates and population-level adult smoking status. One hundred and four Kentucky counties. The sample was comprised of 14,184 Kentucky participants with complete demographic information collected from the 2009-2010 Behavioral Risk Factor Surveillance System (BRFSS). Individual-level demographics and smoking status from the BRFSS; county-level urban/rural status; quitline rates; and smoke-free policy status. Given the hierarchical structure of the dataset, with BRFSS respondents nested within county, multilevel modeling was used to determine the predictors of smoking status. For every 1-unit increase in the county-level call rate the likelihood of current smoking status decreased by 9%. Compared to those living in communities without a policy, those in communities with a smoke-free public policy were 18% less likely to be current smokers. Limitations include quitline call rate as the sole indicator of cessation demand, as well as the cross-sectional design. Communities with smoke-free policies and higher rates of quitline use have lower rates of adult smoking.

Using multivariate logistic regression, subjects who reported reduced smoking or who reported smoking cessation were compared with subjects who continued the habit unchanged. RESULTS: After 5 years 13% of the men and 9% of the women had reduced their tobacco...... consumption, and 9 and 7%, respectively, had quit altogether. Smoking reduction was strongly associated with high tobacco consumption (25+ g/day) at baseline and also with severely impaired lung function (FEV(1) 25). Predictors of smoking cessation included impaired lung...... function and a tobacco consumption of 15-24 g/day. Additional determinants of smoking reduction and cessation such as inhalation habits and sociodemographic variables differed by gender. CONCLUSIONS: Several predictors of smoking reduction and cessation were identified, indicating that these subgroups...

  11. Cigarette smoking and DNA methylation

    Lee, Ken W. K.; Pausova, Zdenka

    2013-01-01

    DNA methylation is the most studied epigenetic modification, capable of controlling gene expression in the contexts of normal traits or diseases. It is highly dynamic during early embryogenesis and remains relatively stable throughout life, and such patterns are intricately related to human development. DNA methylation is a quantitative trait determined by a complex interplay of genetic and environmental factors. Genetic variants at a specific locus can influence both regional and distant DNA methylation. The environment can have varying effects on DNA methylation depending on when the exposure occurs, such as during prenatal life or during adulthood. In particular, cigarette smoking in the context of both current smoking and prenatal exposure is a strong modifier of DNA methylation. Epigenome-wide association studies have uncovered candidate genes associated with cigarette smoking that have biologically relevant functions in the etiology of smoking-related diseases. As such, DNA methylation is a potential mechanistic link between current smoking and cancer, as well as prenatal cigarette-smoke exposure and the development of adult chronic diseases. PMID:23882278

    Full Text Available Abstract Background Undiagnosed airflow limitation is common in the general population and is associated with impaired health and functional status. Smoking is the most important risk factor for this condition. Although primary care practitioners see most adult smokers, few currently have spirometers or regularly order spirometry tests in these patients. Brief medical advice has shown to be effective in modifying smoking habits in a large number of smokers but only a small proportion remain abstinent after one year. The aim of this study is to evaluate the effectiveness of regular reporting of spirometric results combined with a smoking cessation advice by a primary care physician on smoking quit rate in adult smokers. Methods/design Intervention study with a randomized two arms in 5 primary care centres. A total of 485 smokers over the age of 18 years consulting their primary care physician will be recruited. On the selection visit all participants will undergo a spirometry, peak expiratory flow rate, test of smoking dependence, test of motivation for giving up smoking and a questionnaire on socio-demographic data. Thereafter an appointment will be made to give the participants brief structured advice to give up smoking combined with a detailed discussion on the results of the spirometry. After this, the patients will be randomised and given appointment for follow up visits at 3, 6, 12 and 24 months. Both arms will receive brief structured advice and a detailed discussion of the spirometry results at visit 0. The control group will only be given brief structured advice about giving up smoking on the follow up. Cessation of smoking will be tested with the carbon monoxide test. Discussion Early identification of functional pulmonary abnormalities in asymptomatic patients or in those with little respiratory symptomatology may provide "ideal educational opportunities". These opportunities may increase the success of efforts to give up smoking and

    Traditionally, nicotine from second hand smoke (SHS), active or passive, has been considered the most prevalent substance of abuse used during pregnancy in industrialized countries. Exposure to environmental tobacco smoke (ETS) is associated with a variety of health effects, including lung cancer and cardiovascular diseases. Tobacco is also a major burden to people who do not smoke. As developing individuals, newborns and children are particularly vulnerable to the negative effects of SHS. In particular, prenatal ETS has adverse consequences during the entire childhood causing an increased risk of abortion, low birth weight, prematurity and/or nicotine withdrawal syndrome. Over the last years, a decreasing trend in smoking habits during pregnancy has occurred, along with the implementation of laws requiring smoke free public and working places. The decrease in the incidence of prenatal tobacco exposure has usually been assessed using maternal questionnaires. In order to diminish bias in self-reporting, objective biomarkers have been developed to evaluate this exposure. The measurement of nicotine and its main metabolite, cotinine, in non-conventional matrices such as cord blood, breast milk, hair or meconium can be used as a non-invasive measurement of prenatal SMS in newborns. The aim of this review is to highlight the prevalence of ETS (prenatal and postnatal) using biomarkers in non-conventional matrices before and after the implementation of smoke free policies and health effects related to this exposure during foetal and/or postnatal life.

We also explored the issues related to and its impact tobacco control research and policy in the Kingdom.Data were collected from various published articles, public data based such as WHO, Geneva and CDC Atlanta. Data were also obtained from surveys conducted by various institutions under The Global Youth Tobacco Survey (GYTS for high school students and Global Adult Tobacco Survey (GATS for medical student. Tobacco importation data and death rates were estimated by various International Organizations.Tobacco importation in Saudi Arabia increased from 1996 to 2012. The proportion of smokers in the KSA almost doubled especially in males from 21% in 1996 to 37% in 2012. Mortality attributable to tobacco in the KSA was estimated to account for 280, 000 premature deaths over the same period (without accounting for smuggled tobacco. The economic burden of tobacco consumption over the last 10 years (2001-2010 in the KSA was 20.5 billion US dollars (based on 2011 prices. Anti-tobacco measures in KSA have been reinforced by the enactment of anti-tobacco laws and collaboration among different government agencies and ministries.If effective tobacco control strategies are not enacted, serious consequences, increasing premature mortality rates among them, will continue to threaten the KSA.

    Smoking during pregnancy is one of the most important avoidable health risks for the unborn child. Gynaecologists and midwives play a fundamental role in the prevention of smoking during pregnancy. However, a large number of health care practitioners still do not address smoking in pregnant patients. We examined whether gynaecologists and midwives engage in screening and counselling of pregnant women and conducting interventions to prevent smoking during pregnancy. Further, we examined the role of gynaecologists' and midwives' control beliefs. Control beliefs involve efficacy expectations--the practitioner's confidence in his capacity to conduct prevention efforts adequately--and outcome expectations--the practitioner's expectation that such prevention efforts are successful in general. A total of 486 gynaecologists and 366 midwives completed a questionnaire on screening of smoking, counselling and other interventions they conduct to prevent smoking during pregnancy. Moreover, gynaecologists and midwives rated their control beliefs regarding their influence on pregnant patients' smoking habits. The majority of gynaecologists and midwives reported screening all pregnant patients regarding smoking, explaining the risks and recommending smoking cessation. By contrast, only a minority engages in more extensive prevention efforts. Strong control beliefs were predictive of a higher likelihood of screening and counselling, as well as of engaging in more extensive interventions. The findings point to the importance of strengthening gynaecologists' and midwives' control beliefs by professional education and training on smoking prevention. © 2012 John Wiley & Sons Ltd.

    The influence of parents' smoking on children's smoking is well known, but few studies have examined the association between grandparents' and grandchildren's smoking. We studied the association between paternal and maternal grandparents' smoking and their grandchildren's tobacco use and assessed whether parents' smoking is a mediator in this process. Data were obtained from a national survey of 12-18-year-old Finns in 2013 (N = 3535, response rate 38%). Logistic regression and mediation analyses were used. Both boys and girls had higher odds for smoking experimentation, daily smoking and other tobacco or tobacco-like product use if their mother, father or any of the four grandparents were current or former smokers. When parents' and grandparents' smoking status were included in the same model, grandparents' smoking generally lost statistical significance. In the mediation analysis, 73% of the total effect of grandparents' smoking on grandchildren's daily smoking was mediated through parents' smoking, 64% on smoking experimentation and 63% on other tobacco or tobacco-like product use. The indirect effect of a mother's smoking was higher than that of a father's. To conclude, paternal and maternal grandparents' smoking increases grandchildren's tobacco use. The influence is mainly, but not completely, mediated through parents' smoking.

    Full Text Available Abstract Background The majority of Polish smokers declare their will to quit smoking and many of them attempt to quit. Although morbidity and mortality from tobacco-related diseases are among the highest in the world, there is a lack of comprehensive cessation support for smokers. We aimed to investigate how Poles, including the medically ill, cope with quitting cigarettes and what their motivations to quit are. Methods Convenience sampling was used for the purpose of the study. Individuals attending several health care units were screened for a history of quit attempts. Ex-smokers were defined as smoking previously at least one cigarette/day but who have no longer been smoking for at least one month. Attempts at quitting were defined as abstaining from cigarettes for at least one day. Data on socio-demographics, tobacco use, quitting behaviors and reasons to quit from 618 subjects (385 ex- and 233 current smokers who fulfilled these criteria were collected with the use of a questionnaire. For the comparison of proportions, a chi-square test was used. Results In the entire study population, 77% of smokers attempted to quit smoking on their own and a similar proportion of smokers (76% used the cold turkey method when quitting. Current smokers were more likely than former smokers to use some form of aid (p = 0.0001, mainly nicotine replacement therapy (68%. The most important reasons for quitting smoking were: general health concern (57%, personal health problems (32% and social reasons (32%. However, 41% of smokers prompted to quitting by personal health problems related to tobacco smoking did not see the link between the two. A small proportion of ex-smokers (3% abstaining from cigarettes for longer than a year were not confident about their self-efficacy to sustain abstinence further. Conclusion The majority of Polish smokers, including patients with tobacco-related diseases, attempt to quit without smoking cessation assistance, thus there is

    2016-01-01

    In this paper, we aim to present an overview of the scientific literature on the link between smoke-free legislation and early-life health outcomes. Exposure to second-hand smoke is responsible for an estimated 166 ,000 child deaths each year worldwide. To protect people from tobacco smoke, the World Health Organization recommends the implementation of comprehensive smoke-free legislation that prohibits smoking in all public indoor spaces, including workplaces, bars and restaurants. The implementation of such legislation has been found to reduce tobacco smoke exposure, encourage people to quit smoking and improve adult health outcomes. There is an increasing body of evidence that shows that children also experience health benefits after implementation of smoke-free legislation. In addition to protecting children from tobacco smoke in public, the link between smoke-free legislation and improved child health is likely to be mediated via a decline in smoking during pregnancy and reduced exposure in the home environment. Recent studies have found that the implementation of smoke-free legislation is associated with a substantial decrease in the number of perinatal deaths, preterm births and hospital attendance for respiratory tract infections and asthma in children, although such benefits are not found in each study. With over 80% of the world’s population currently unprotected by comprehensive smoke-free laws, protecting (unborn) children from the adverse impact of tobacco smoking and SHS exposure holds great potential to benefit public health and should therefore be a key priority for policymakers and health workers alike.

    The present work is an analysis of whether adoption of state clean indoor air laws (SCIALs) covering bars reduces the proportion of bartenders who smoke primarily by reducing smoking among people already employed as bartenders when restrictions are adopted or by changing the composition of the bartender workforce with respect to smoking behaviours. Logistic regressions were estimated for a variety of smoking outcomes, controlling for individual demographic characteristics, state economic characteristics, and state, year, and month fixed effects, using data on 1380 bartenders from the 1992-2007 Tobacco Use Supplement to the Current Population Survey combined with data on SCIALs from ImpacTeen. State restrictions on smoking in bars are negatively associated with whether a bartender smokes, with a 1-point increase in restrictiveness (on a scale of 0-3) associated with a 5.3% reduction in the odds of smoking. Bar SCIALs are positively associated with the likelihood a bartender reports never having smoked cigarettes but not with the likelihood a bartender reports having been a former smoker. State clean indoor air laws covering bars appear to reduce smoking among bartenders primarily by changing the composition of the bartender workforce with respect to smoking rather than by reducing smoking among people already employed as bartenders when restrictions are adopted. Such laws may nonetheless be an important public health tool for reducing secondhand smoke.

    Objective To determine the associations of socio-economic and psychosocial factors with active and passive smoking in older adults. Methods Using a standard interview method, we examined random samples of 6071 people aged≥60 years in 5 provinces of China during 2007-2009. Results World age-standardised prevalence for current and former smoking in men was 45.6% and 20.5%, and in women 11.1%and 4.5%. Current smoking reduced with older age but increased with men, low socioeconomic status (SES), alcohol drinking, being never-married, pessimistic and depressive syndromes. Former smoking was associated with men, secondary school education, a middle-high income, being a businessman, being widowed, less frequencies of visiting children/relatives and friends, and worrying about children. Among 3774 never-smokers, the prevalence of passive smoking was 31.5%, and the risk increased with women, low SES, alcohol drinking, being married, having a religious believe, and daily visiting children/relatives. There were sex differences in the associations, and an interaction effect of education and income on smoking and passive smoking. Conclusion Older Chinese had a higher level of smoking and passive smoking than those in high income countries, reflecting China’s failures in controlling smoking. The associations with low SES and different psychosocial aspects and sex differences suggest preventative strategies for active and passive smoking.

    Issue addressed Tobacco consumption contributes to health disparities among Aboriginal Australians who experience a greater burden of smoking-related death and diseases. This paper reports findings from a baseline survey on factors associated with smoking, cessation behaviours and attitudes towards smoke-free homes among the Aboriginal population in inner and south-western Sydney. Methods A baseline survey was conducted in inner and south-western Sydney from October 2010 to July 2011. The survey applied both interviewer-administered and self-administered data collection methods. Multiple logistic regression was performed to determine the factors associated with smoking. Results Six hundred and sixty-three participants completed the survey. The majority were female (67.5%), below the age of 50 (66.6%) and more than half were employed (54.7%). Almost half were current smokers (48.4%) with the majority intending to quit in the next 6 months (79.0%) and living in a smoke-free home (70.4%). Those aged 30-39 years (AOR 3.28; 95% CI: 2.06-5.23) and the unemployed (AOR 1.67; 95% CI: 1.11-2.51) had higher odds for current smoking. Participants who had a more positive attitude towards smoke-free homes were less likely to smoke (AOR 0.79; 95% CI: 0.74-.85). Conclusions A high proportion of participants were current smokers among whom intention to quit was high. Age, work status and attitudes towards smoke-free home were factors associated with smoking. So what? The findings address the scarcity of local evidence crucial for promoting cessation among Aboriginal tobacco smokers. Targeted promotions for socio-demographic subgroups and of attitudes towards smoke-free homes could be meaningful strategies for future smoking-cessation initiatives.

    Oral habits like chewing and smoking are main causes of oral cancer, which has a higher mortality rate than many other cancer forms. Currently, the long term survival rate of oral cancer is less than 50%, as a majority of cases are detected very late. The clinician's main challenge is to differentiate among a multitude of red, white, or ulcerated lesions. Hence, new noninvasive, reliable, and fast techniques for the discrimination of oral cavity disorders are to be developed. This study includes autofluorescence spectroscopic screening of normal volunteers with and without lifestyle oral habits and patients with oral submucous fibrosis (OSF). The spectra from different sites of habitués, non-habitués, and OSF patients were analyzed using the intensity ratio, redox ratio, and linear discriminant analysis (LDA). The spectral disparities among these groups are well demonstrated in the emission regions of collagen and Flavin adenine dinucleotide. We observed that LDA gives better efficiency of classification than the intensity ratio technique. Even the differentiation of habitués and non-habitués could be well established with LDA. The study concludes that the clinical application of autofluorescence spectroscopy along with LDA, yields spontaneous screening among individuals, facilitating better patient management for clinicians and better quality of life for patients.

    The aims of this study were to estimate the prevalence of smoking among SEPAR members, and their approach to smoking cessation in their patients. An online survey was completed by 640 members (496 pulmonologists, 45 nurses, 34 thoracic surgeons, 37 physiotherapists, and 28 other specialists). Of the members interviewed, 5% confessed that they were smokers: 3.5% pulmonologists; 8.9% nurses; 8.8% thoracic surgeons, and 13.5% physiotherapists. A total of 96% of members assign a lot or quite a lot of importance to setting an example; 98% of members always or often ask their patients about their smoking habit. The most effective anti-smoking intervention, according to 77% of members, is a combination of drugs and psychological support. These results are an indicator of the awareness and commitment of SEPAR members to smoking and its cessation. Copyright © 2016 SEPAR. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available Cigarette smoking is widespread among HIV-infected patients, who confront increased risk of smoking-related co-morbidities. The effects of HIV infection and HIV-related variables on smoking and smoking cessation are incompletely understood. We investigated the correlates of smoking and quitting in an HIV-infected cohort using a validated natural language processor to determine smoking status.We developed and validated an algorithm using natural language processing (NLP to ascertain smoking status from electronic health record data. The algorithm was applied to records for a cohort of 3487 HIV-infected from a large health care system in Boston, USA, and 9446 uninfected control patients matched 3:1 on age, gender, race and clinical encounters. NLP was used to identify and classify smoking-related portions of free-text notes. These classifications were combined into patient-year smoking status and used to classify patients as ever versus never smokers and current smokers versus non-smokers. Generalized linear models were used to assess associations of HIV with 3 outcomes, ever smoking, current smoking, and current smoking in analyses limited to ever smokers (persistent smoking, while adjusting for demographics, cardiovascular risk factors, and psychiatric illness. Analyses were repeated within the HIV cohort, with the addition of CD4 cell count and HIV viral load to assess associations of these HIV-related factors with the smoking outcomes.Using the natural language processing algorithm to assign annual smoking status yielded sensitivity of 92.4, specificity of 86.2, and AUC of 0.89 (95% confidence interval [CI] 0.88-0.91. Ever and current smoking were more common in HIV-infected patients than controls (54% vs. 44% and 42% vs. 30%, respectively, both P<0.001. In multivariate models HIV was independently associated with ever smoking (adjusted rate ratio [ARR] 1.18, 95% CI 1.13-1.24, P <0.001, current smoking (ARR 1.33, 95% CI 1.25-1.40, P<0.001, and

  3. Women and Smoking: Global Challenge

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Global tobacco control has led to a reduction in smoking prevalence and mortality in men, while the rates among women have not followed the same declining rates or patterns. Tobacco-induced diseases, including those unique to women (reproductive complications, cervical and breast cancer are becoming increasingly prevalent among women. Unfortunately, many tobacco control policies and cessation programs have been found to be less effective for women than men. This is alarming as disease risk for lung cancer, CVD, osteoporosis, and COPD, associated with smoking, is higher among women. Women are also more likely to be exposed to secondhand tobacco smoke and subsequent morbidity. Finally, quitting smoking appears to be harder for women than men. Current tobacco control and surveillance data come primarily from high resource countries. WHO estimates that in 2030, in low and medium resource countries, 7 out of 10 deaths will be smoking-related. While the prevalence of smoking in women is relatively low in these countries, more information is needed regarding their patterns of tobacco use uptake, and subsequent health outcomes, as theirs differ from men. Tobacco use in women is greatly influenced by social, cultural and political determinants, and needs to be conceptualized within an intersectional framework.

    Kepler-452b is currently the best example of an Earth-size planet in the habitable zone of a sun-like star, a type of planet whose number of detections is expected to increase in the future. Searching for biosignatures in the supposedly thin atmospheres of these planets is a challenging goal that requires a careful selection of the targets. Under the assumption of a rocky-dominated nature for Kepler-452b, we considered it as a test case to calculate a temperature-dependent habitability index, h050, designed to maximize the potential presence of biosignature-producing activity. The surface temperature has been computed for a broad range of climate factors using a climate model designed for terrestrial-type exoplanets. After fixing the planetary data according to the experimental results, we changed the surface gravity, CO2 abundance, surface pressure, orbital eccentricity, rotation period, axis obliquity and ocean fraction within the range of validity of our model. For most choices of parameters, we find habitable solutions with h050 > 0.2 only for CO2 partial pressure p_CO_2 ≲ 0.04 bar. At this limiting value of CO2 abundance, the planet is still habitable if the total pressure is p ≲ 2 bar. In all cases, the habitability drops for eccentricity e ≳ 0.3. Changes of rotation period and obliquity affect the habitability through their impact on the equator-pole temperature difference rather than on the mean global temperature. We calculated the variation of h050 resulting from the luminosity evolution of the host star for a wide range of input parameters. Only a small combination of parameters yields habitability-weighted lifetimes ≳2 Gyr, sufficiently long to develop atmospheric biosignatures still detectable at the present time.

    2013-01-01

    The harmful effects of smoking during pregnancy have been well documented within the literature (Eastham and Gosakan 2010; British Medical Association (BMA) 2004). However, although the number of women smoking during pregnancy has fallen over the last few years, this still remains a major health concern for both women and their families. This paper aims to explore recent media campaigns and social policies focusing on smoking in pregnancy and the general population. Midwives need to be aware of current policies with regard to smoking cessation to enable high quality evidence based information and support to be provided at an optimum time in women's lives.

    Disordered bowel habits might influence quality of life after bariatric surgery. Different types of bariatric operations-gastric banding (AGB), Roux-en-Y gastric bypass (RYGB), or biliopancreatic diversion (BPD)-might alter bowel habits as a consequence of the surgical procedure used. Whether change in bowel habits affects quality of life after AGB, RYGB, or BPD differently is unknown. The study group contained 290 severely obese patients undergoing bariatric surgery between August 1996 and September 2004 [BPD: n = 103, 64.1% women, age 43 +/- 1 years (mean +/- SEM), BMI 53.9 +/- 0.9 kg/m(2), weight 153.4 +/- 2.9 kg; Roux-en-Y gastric bypass: n = 126, 73.0% women, age 43 +/- 1 years, BMI 44.2 +/- 0.3 kg/m(2), weight 123.8 +/- 1.5 kg; adjustable gastric banding (AGB): n = 61, 57.4% women, age 44 +/- 1 years, BMI 49.9 +/- 0.5 kg/m(2), weight 146.1 +/- 2.0 kg). Changes in bowel habits, flatulence, flatus odor, and effects on social life were estimated at least 4 months after surgery using a self-administered questionnaire. Fecal consistency changed significantly after surgery. Loose stools and diarrhea were more frequent after BPD and RYGB (P flatus affecting social life was more frequent after BPD than after either RYGB or AGB (P flatus frequency increased after BPD and RYGB, and patients were more bothered by their malodorous flatus than after AGB (all P Flatus severity score was highest in BPD, intermediate in RYGB, and lowest in AGB patients (all P < 0.001), a difference that was not influenced by frequency of metabolic syndrome before and after surgery. Moreover, observation period after surgery had no influence on overall results of bowel habits. Subsore quality of life bariatric analysis and reporting outcome system (BAROS) scores were largely similar between all three groups. However, flatulence severity score correlated inversely with quality of life estimated by BAROS in BPD and RYGB, but not in AGB patients. The type of bariatric surgery affects bowel

    Limited research has been published regarding the association between stuttering and substance use. An earlier study provided no evidence for such an association, but the authors called for further research to be conducted using a community sample. The present study used data from a community sample to investigate whether an association between stuttering and alcohol consumption or regular smoking exists in late adolescence and adulthood. Regression analyses were carried out on data from a birth cohort study, the National Child Development Study (NCDS), whose initial cohort included 18,558 participants who have since been followed up until age 55. In the analyses, the main predictor variable was parent-reported stuttering at age 16. Parental socio-economic group, cohort member's sex and childhood behavioural problems were also included. The outcome variables related to alcohol consumption and smoking habits at ages 16, 23, 33, 41, 46, 50 and 55. No significant association was found between stuttering and alcohol consumption or stuttering and smoking at any of the ages. It was speculated that the absence of significant associations might be due to avoidance of social situations on the part of many of the participants who stutter, or adoption of alternative coping strategies. Because of the association between anxiety and substance use, individuals who stutter and are anxious might be found to drink or smoke excessively, but as a group, people who stutter are not more likely than those who do not to have high levels of consumption of alcohol or nicotine.

    From 1965 to 1990, the prevalence of cigarette smoking among US adults (aged > or = 18 years) fell steadily and substantially. Data for the 1990s suggest that the smoking initiation rate is increasing and that the decline in the prevalence of smoking may have stalled, raising the fear that the historical 25-year decline will not continue. The authors used a new dynamic forecasting model to show that although the decline may slow down, the demographics of smoking imply that prevalence will inexorably continue to decline over the next several decades, even without any intensified efforts aimed at tobacco control. The authors estimated and validated the model using historical (1965-1993) data collected by the National Health Interview Surveys on the prevalence of smoking among adults. Their results indicate that the current increase in the smoking initiation rate partially explains the fact that the prevalence of smoking has apparently leveled off, but even if the most grim assumptions about future initiation rates are used, the prevalence of smoking among adults will continue to decline for several more decades. The authors predict that if current initiation and cessation behaviors persist, the prevalence of smoking among adults will automatically decline from its current level of 25% to 15-16% by the second quarter of the next century. Even so, smoking will remain the nation's leading cause of premature death.

    According to recent models of drug dependence, attentional bias for drug cues provides an index of vulnerability to drug-taking and relapse. The present study examined attentional bias for smoking-related information in pregnant women and its relationship with smoking experience and attitudes. Participants were 71 pregnant women (35 without smoking experience; 36 with experience of smoking, of whom 16 reported currently smoking). Attentional bias was assessed from the interference index of smoking-related words on a modified Stroop task. The attentional bias for smoking cues was positively associated with smoking experience, and with more favourable general attitudes to smoking (i.e. incentive-related bias). The bias was also greater in women who perceived greater harm of passive smoking to their foetus (i.e. threat-related bias), which was independent of smoking experience. Results indicate that attentional bias for smoking-related cues is independently associated with both incentive-related (reward) and threat-related (aversive) evaluations of cigarette smoking in pregnant women. This work highlights the need for longitudinal research to investigate whether the attentional bias provides a cognitive index of vulnerability for persistent smoking behaviour both during and after pregnancy.

  10. Smoke and mirrors: magnified beliefs that cigarette smoking suppresses weight.

    2007-10-01

    Research suggests that for some smokers, weight concerns interfere with smoking cessation. Studies with individuals with eating disorders and weight concerns have indicated that weight-concerned individuals place undue faith in the effectiveness of certain weight control strategies; i.e., adopt a brand of magical thinking pertaining to food rules and dieting behaviors. The current study investigated whether weight-concerned smokers endorsed exaggerated beliefs in the ability of smoking to suppress body weight. Participants were 385 individuals undergoing treatment for smoking cessation. Prior to treatment, participants completed the Smoking Consequences Questionnaire-Adult (SCQ-A), the Dieting and Bingeing Severity Scale, and the Perceived Risks and Benefits Questionnaire (PBRQ). Results indicated that heightened beliefs in the effectiveness of smoking to control weight were related to eating and weight concerns; specifically, strong associations were observed between SCQ-A Weight Control scores and fear of weight gain, loss of control over eating, and body dissatisfaction. Although SCQ-A Weight Control scores were related to (self-reported) weight gain during a previous quit attempt, scores did not predict actual weight gain over the course of the cessation trial. Reported weight gain at previous attempts was also unrelated to actual weight gain over the current trial. These findings indicate that eating and weight-concerned smokers may benefit from psychoeducation concerning the relatively modest and temporary ability of nicotine to suppress weight.

    OBJECTIVES: The inverse relationship between socioeconomic status (SES) and smoking is typically seen in terms of the greater economic and social resources of advantaged groups, but it may also relate to cultural resources. This study aims to test theories of symbolic distinction by examining relationships between smoking and ostensibly unrelated cultural preferences. METHODS: Using the 1993 General Social Survey, ordinal logistic regression models, and a three-category dependent variable (never, former, and current smoker), the analysis estimates relationships of musical likes and dislikes with smoking while controlling for SES and social strain. RESULTS: Preferences for classical music are associated with lower smoking, while preferences for bluegrass, jazz, and heavy metal music are associated with higher smoking. CONCLUSIONS: The results suggest that SES groups may use smoking, like other cultural tastes, to distinguish their lifestyles from those of others.

  12. Habit formation: implications for alcoholism research.

    Characteristics of individuals with severe alcohol use disorders include heightened cue sensitivity, compulsive seeking, craving, and continued alcohol use in the face of negative consequences. Animal models are useful for understanding behavioral and neurological mechanisms underlying problematic alcohol use. Seeking of operant reinforcers including alcohol is processed by two mechanisms, commonly referred to as "goal-directed" (action-outcome) and "habitual" (stimulus-response). As substance use disorders are characterized by continued use regardless of unfavorable outcomes, it is plausible that drug use causes an unnatural disruption of these mechanisms. We present a critical analysis of literature pertaining to behavioral neuroscience alcoholism research involving habit formation. Traditionally, when operant behavior is unaffected by a loss of subjective value of a reinforcer (devaluation), the behavior is considered habitual. Acquisition of instrumental behavior requires corticostriatal mechanisms that depend heavily on the prefrontal cortex and ventral striatum, whereas practiced behavior is more predominantly controlled by the dorsal striatum. Dopaminergic signaling is necessary for the neurological adaptations involved in stimulus-response action, and drugs of abuse appear to facilitate habitual behavior through high levels of dopamine release. Evidence suggests that the use of alcohol as a reinforcer expedites habit formation, and that a history of alcohol use produces alterations in striatal morphology, aids habit learning for non-psychoactive reinforcers, and promotes alcohol drinking despite aversive adulterants. In this review, we suggest directions for future alcoholism research that seeks to measure action made despite a devalued outcome, including procedural modifications and genotypic, pharmacological, or neurological manipulations. Most alcoholism models currently in use fail to reach substantial blood ethanol concentrations, a shortcoming that

    Organizations recommend media literacy to reduce tobacco use, and higher media literacy has been associated with lower smoking among high school students. The relationship between smoking media literacy and tobacco use, however, has not been systematically studied among college students. The purpose of this study was to determine the association between smoking and smoking media literacy among college students. We conducted the National College Health Assessment (NCHA) at a large, urban university, adding six items measuring smoking media literacy. A total of 657 students responded to this random sample e-mail survey. We used multiple logistic regression to determine independent associations between smoking media literacy items and current smoking. The media literacy scale was internally consistent (alpha = 0.79). Of the respondents, 21.5% reported smoking cigarettes over the past 30 days. In a fully adjusted multivariate model, participants with medium media literacy had an odds ratio (OR) for current smoking of 0.45 (95% CI = 0.29, 0.70), and those with high media literacy had an OR for current smoking of 0.38 (95% CI = 0.20, 0.70). High smoking media literacy is independently associated with lower odds of smoking. Smoking media literacy may be a valuable construct to address in college populations.

  15. Mapping the Nearest Stars for Exotic Habitable Worlds

    Exoplanets are planets orbiting stars other than the sun. Thousands of exoplanets are known and thousands of more planet candidates have been found. Until now, the dominant focus on habitable worlds has been on Earth-like planets, because Earth is the only known planet with life. Yet exoplanets are astonishingly diverse—in terms of their masses, densities, orbits, and host star types—and this diversity motivates a radical extension of what conventionally constitutes a habitable planet. The race to find habitable exoplanets has accelerated with the realization that “big Earths” transiting small stars can be both discovered and characterized with current technology. Moreover, technology for space-based direct imaging of Earth analogs has been rapidly maturing. The ambitious goal of inferring signs of life via biosignature gases in an exoplanet atmosphere, once only a futuristic thought, is now within reach.

    In this work various factors on the habitability were considered, focusing on conditions irrespective of the central star's radiation, to see the role of specific planetary body related effects. These so called planetary factors were evaluated to identify those trans-domain issues where important information is missing but good chance exit to be filled by new knowledge that might be gained in the next decade(s). Among these strategic knowledge gaps, specific issues are listed, like occurrence of radioactive nucleides in star forming regions, models to estimate the existence of subsurface liquid water from bulk parameters plus evolutionary context of the given system, estimation on the existence of redox gradient depending on the environment type etc. These issues require substantial improvement of modelling and statistical handling of various cases, as "planetary environment types". Based on our current knowledge it is probable that subsurface habitability is at least as frequent, or more frequent than surface habitability. Unfortunately it is more difficult from observations to infer conditions for subsurface habitability, but specific argumentation might help with indirect ways, which might result in new methods to approach habitability in general.

    This study examined the interplay between sociodemographic factors and parental smoking history in shaping the smoking behavior of Israeli women (N = 302). The study was conducted in the Negev region, which is characterized by a high proportion of immigrants and high percentage of low socioeconomic and educational groups. The specific objectives of this study were to examine: (1) The prevalence and characteristics of women smokers, ex-smokers and never-smokers; and (2) the contribution of education and parent smoking history to women's current smoking. Low levels of education, being Israeli born or veteran immigrants of European-American origin significantly increased the risk of smoking, whereas an orthodox lifestyle and new immigrant status significantly reduced the likelihood of smoking. Occasional smokers reported significantly higher primary care utilization than never smokers. A significant relationship between smoking and pain, gynecological symptoms and depression was found. Results indicate that childhood exposure to maternal smoking was a significant risk factor for smoking, whereas paternal past smoking negatively affects smoking in women. Also, results show that parental educational level affects women's smoking behavior indirectly by influencing their own educational attainment, which in turn is negatively associated with the likelihood of smoking. Mothers with higher education were more likely to smoke, an effect that was reversed for their daughters. Our results demonstrate how demographic, parental and lifestyle factors affect women's smoking in a multi-ethnic society and highlight the need to examine both generational and intergenerational effects.

    Smoke is known to cause electrical equipment failure, but the likelihood of immediate failure during a fire is unknown. Traditional failure assessment techniques measure the density of ionic contaminants deposited on surfaces to determine the need for cleaning or replacement of electronic equipment exposed to smoke. Such techniques focus on long-term effects, such as corrosion, but do not address the immediate effects of the fire. This document reports the results of tests on the immediate effects of smoke on electronic equipment. Various circuits and components were exposed to smoke from different fields in a static smoke exposure chamber and were monitored throughout the exposure. Electrically, the loss of insulation resistance was the most important change caused by smoke. For direct current circuits, soot collected on high-voltage surfaces sometimes formed semi-conductive soot bridges that shorted the circuit. For high voltage alternating current circuits, the smoke also tended to increase the likelihood of arcing, but did not accumulate on the surfaces. Static random access memory chips failed for high levels of smoke, but hard disk drives did not. High humidity increased the conductive properties of the smoke. The conductivity does not increase linearly with smoke density as first proposed; however, it does increase with quantity. The data can be used to give a rough estimate of the amount of smoke that will cause failures in CMOS memory chips, dc and ac circuits. Comparisons of this data to other fire tests can be made through the optical and mass density measurements of the smoke.

    Among the key-parameters to characterize habitability are presence or availability of liquid water, an appropriate temperature range, and the time scale of reference. These criteria for habitability are discussed and described from the point of view of water- and ice-physics, and it is shown that liquid water may exist in the sub-surfaces of planetary bodies like Mars, and possibly of inner asteroids and internally heated ice-moons. Water can remain fluid there also at temperatures far below the "canonical" 0 °C. This behaviour is made possible as a consequence of the freezing point depression due to salty solutes in water or "brines", as they can be expected to exist in nature more frequently than pure liquid water. On the other hand, low temperatures cause a slowing down of chemical processes, as can be described by Arrhenius's relation. The resulting smaller reaction rates probably will have the consequence to complicate the detection of low-temperature life processes, if they exist. Furthermore, the adaptation potential of life is to be mentioned in this context as a yet partially unknown process. Resulting recommendations are given to improve the use of criteria to characterize habitable conditions.

    Little is known about the magnitude and nature of the combined effect of chronic kidney disease (CKD) and smoking on cardiovascular diseases. We studied this in a Japanese population using a pooled analysis of 15,468 men and 19,154 women aged 40-89 years enrolled in 8 cohort studies. The risk of mortality from all-causes and cardiovascular disease was compared in 6 gender-specific categories of baseline CKD status (non-CKD or CKD) and smoking habits (lifelong never smoked, former smokers, or currently smoking). CKD was defined as a decreased level of estimated glomerular filtration rate (under 60 ml/min per 1.73 m(2)) and/or dipstick proteinuria. Hazard ratios were estimated for each category, relative to never smokers without CKD. During the follow-up period (mean 14.8 years), there were 6771 deaths, 1975 of which were due to cardiovascular diseases. In both men and women, current or former smokers with CKD had the first or second highest crude mortality rates from all-cause and cardiovascular diseases among the 6 categories. After adjustment for age and other major cardiovascular risk factors, the hazard ratios in male and female current smokers with CKD were 2.26 (95% confidence interval, 1.95-2.63) and 1.78 (1.36-2.32) for all-causes, and 2.66 (2.04-3.47) and 1.71 (1.10-2.67) for cardiovascular diseases, respectively. Thus, coexistence of CKD and smoking may markedly increase the risk of all-cause and cardiovascular mortality.

    Context: A growing number of cities, districts, counties and states across the globe are going smoke-free. While an Indian national law namely Cigarettes and Other Tobacco Products Act (COTPA) exists since 2003 and aims at protecting all the people in our country; people still smoke in public places. Aim: This study assessed knowledge and perceptions about smoking, SHS and their support for Smoke-free laws among people residing in Mohali district, Punjab. Materials and Methods: This cross-sectional study was conducted in Mohali district of Punjab, India. A sample size of 1600 people was obtained. Probability Proportional to Size technique was used for selecting the number of individuals to be interviewed from each block and also from urban and rural population. Statistical Analysis Used: We estimated proportions and tested for significant differences by residence, smoking status, literacy level and employment level by means of the chi-square statistics. Statistical software SPSS for Windows version 20 was used for analysing data . Results: The overall prevalence of current smoking among study participants was 25%. Around 96% were aware of the fact that smoking is harmful to health, 45% viewed second-hand smoke to be equally harmful as active smoking, 84.2% knew that smoking is prohibited in public places and 88.3% wanted the government to take strict actions to control the menace of public smoking. Multivariate logistic regression analysis showed that people aged 20 years and above, unemployed, urban, literate and non-smokers had significantly better perception towards harms of smoking. The knowledge about smoke free provisions of COTPA was significantly better among males, employed individuals, urban residents, and literate people. Conclusions: There was high knowledge about deleterious multi-dimensional effects of smoking among residents and a high support for implementation of COTPA. Efforts should be taken to make Mohali a "smoke-free district".

    Exoplanet surveys have recently revealed nearby planets orbiting within stellar habitable zones. This highly-anticipated breakthrough brings us one step closer in our quest to identify cosmic biosignatures, the indicators of extrasolar life. To achieve our goal, we must first study the atmospheres of these temperate worlds to measure their compositions and determine the prevalence of obscuring clouds. Using observations from the K2 mission, Co-I Montet recently announced the discovery of a 2.2 Earth-radii planet within the habitable zone of its relatively bright, nearby M dwarf parent star, K2-18. This temperate world is currently the best habitable-zone target for atmospheric characterization. Congruent with currently planned HST observations, we propose a Spitzer program to measure the transmission spectrum of the first habitable-zone exoplanet. Both telescopes are essential to revealing K2-18b's chemical composition. In a cloud-free, hydrogen-dominated atmosphere, the precision achieved by these measurements will be sufficient to detect methane, ammonia, and water vapor, which are the dominant C, N, and O bearing species at these temperatures. In turn, elemental abundance constraints from a primordial atmosphere can tell us about the composition of a protoplanetary disk in which Earth-like planets could have formed. Conversely, if the atmosphere contains thick clouds then the multi-wavelength observations from K2, HST, and Spitzer will constrain the clouds' properties. Because temperature plays a key role in the formation of clouds, their detection within the atmosphere of this habitable-zone exoplanet would be an important signpost that serves as a guide to future investigations of smaller, rocky exoplanets. As K2 continues discovering more habitable-zone planets, it is imperative that we perform spectral reconnaissance with Spitzer to determine their physical characteristics and begin understanding the prevalence of potentially-obscuring clouds prior to the

    VO2max is associated with many factors, including age, gender, physical activity, and body composition. It is popularly believed that habitual smoking lowers aerobic fitness. PURPOSE: to determine the effect of habitual smoking on VO2max after controlling for age, gender, activity and BMI. METHODS: 2374 men and 375 women employed at the NASA/Johnson Space Center were measured for VO2max by indirect calorimetry (RER>=1.1), activity by the 11 point (0-10) NASA Physical Activity Status Scale (PASS), BMI and smoking pack-yrs (packs day*y of smoking). Age was recorded in years and gender was coded as M=1, W=0. Pack.y was made a categorical variable consisting of four levels as follows: Never Smoked (0), Light (1-10), Regular (11-20), Heavy (>20). Group differences were verified by ANOVA. A General Linear Models (GLM) was used to develop two models to examine the relationship of smoking behavior on VO2max. GLM #1(without smoking) determined the combined effects of age, gender, PASS and BMI on VO2max. GLM #2 (with smoking) determined the added effects of smoking (pack.y groupings) on VO2max after controlling for age, gender, PASS and BMI. Constant errors (CE) were calculated to compare the accuracy of the two models for estimating the VO2max of the smoking subgroups. RESULTS: ANOVA affirmed the mean VO2max of each pack.y grouping decreased significantly (psmoking exposure increased. GLM #1 showed that age, gender, PASS and BMI were independently related with VO2max (R2 = 0.642, SEE = 4.90, pSmoked, the effects on VO2max from Light and Regular smoking habits were -0.83 and -0.85 ml.kg- 1.min-1 respectively (peffect of Heavy smoking on VO2max was -2.56 ml.kg- 1.min-1 (psmoking group in GLM #2 was smaller than the CE s of the smoking group counterparts in GLM #1. CONCLUSIONS: After accounting for the effects of gender, age, PASS and BMI the effect of habitual smoking on reducing VO2max is minimal, about 0.85 ml/kg/min, until the habit exceeds 20 pack.y at which point an

    Background Habit is defined as a process whereby an impulse towards behaviour is automatically initiated upon encountering a setting in which the behaviour has been performed in the past. A central tenet of habit theory is that habit overrides intentional tendencies in directing behaviour, such that as habit strength increases, intention becomes less predictive of behaviour. Yet, evidence of this effect has been methodologically limited by modelling the impact of positively-correlated habits ...

    A magnitude 7.1 earthquake hit Canterbury in September 2010. This earthquake and associated aftershocks took the lives of 185 people and drastically changed residents' living, working, and social conditions. To explore the impact of the earthquakes on smoking status and levels of tobacco consumption in the residents of Christchurch. Semistructured interviews were carried out in two city malls and the central bus exchange 15 months after the first earthquake. A total of 1001 people were interviewed. In August 2010, prior to any earthquake, 409 (41%) participants had never smoked, 273 (27%) were currently smoking, and 316 (32%) were ex-smokers. Since the September 2010 earthquake, 76 (24%) of the 316 ex-smokers had smoked at least one cigarette and 29 (38.2%) had smoked more than 100 cigarettes. Of the 273 participants who were current smokers in August 2010, 93 (34.1%) had increased consumption following the earthquake, 94 (34.4%) had not changed, and 86 (31.5%) had decreased their consumption. 53 (57%) of the 93 people whose consumption increased reported that the earthquake and subsequent lifestyle changes as a reason to increase smoking. 24% of ex-smokers resumed smoking following the earthquake, resulting in increased smoking prevalence. Tobacco consumption levels increased in around one-third of current smokers.

    Full Text Available Mesmo com os esforços intensivos para o controle do tabagismo nas últimas décadas, uma proporção substancial de pessoas inicia a fumar ou mantém-se fumando apesar do pleno conhecimento dos malefícios do hábito. Os estudos têm focado atualmente as bases genéticas da adição nicotínica. O tabagismo tem sido associado a vários polimorfismos genéticos, mas os fatores ambientais também devem ser enfatizados. Esta revisão apresenta alguns dos principais dados disponíveis dos estudos genéticos sobre o comportamento tabágico. Esta linha de pesquisa poderá, no futuro, ajudar os clínicos a individualizar o tipo, a dosagem e a duração do tratamento da dependência tabágica, conforme o genótipo de cada fumante, maximizando a eficácia do esquema proposto.Despite the considerable efforts made in the fight against smoking in the last decades, there are still substantial numbers of people who, in full knowledge of the health hazards, begin smoking or continue smoking. Recent studies have focused on the genetic bases of the nicotine addiction. Various genetic polymorphisms have been associated with smoking. However, environmental factors have also been shown to play a role. In this review, we present some of the principal data collected in genetic studies of smoking behavior. The results obtained through this line of research will eventually aid clinicians in individualizing the type, dosage and duration of treatment for patients with nicotine dependence in accordance with the genotype of each smoker, thereby maximizing the efficacy of the proposed treatment regimen.

    Among health enhancement activities which have been promoted at various worksites smoking cessation is the most common but is seldom very successful. Smoking cessation programs have almost always neglected individual background factors. The main purpose of this study is to evaluate the factors critical to behavior modification with respect to smoking cessation at worksites. Five hundred and sixty-five chemical factory workers responded to questionnaires on their smoking behavior lifestyle, drinking habits, opinions on smoking, opinions on quitting smoking, knowledge about the effects of smoking on health, and type A behavior pattern. Two hundred thirty two male smokers (age 20-58) were chosen for the smoking cessation program, which was administered during the periodical health examinations. One year after receiving the anti-smoking education their smoking behaviors were again surveyed. Fifteen employees had quit smoking and 79 had reduced consumption by more than 10 cigarettes per day. A principal component analysis was performed in order to extract factors from the numerous items on the questionnaire. Principal component scores were compared between the group that had stopped smoking or had cut back by more than 10 cigarettes per day (Responsive Group) and the rest of the smokers (Unresponsive Group). Principal component scores, which appear to be related to levels of individual health consciousness and levels of regular exercise, were significantly higher in the responsive group than in the unresponsive group. No significant differences were noted between the two groups for principal component scores for kn
