CIGARETTE SMOKING AMONG HIGH SCHOOL STUDENTS IN RURAL AREAS OF THAILAND

The purpose of this study was to identify the smoking prevalence among high school students in rural areas of Thailand and the factors associated with their smoking habits. The sample population was comprised of 946 volunteer students of both sexes enrolled in the twelfth grade classes of the 1981-82 school year in randomly chosen regional public high schools throughout the country. Data were obtained from a formal self-administered questionnaire survey. The comparisons were treated by classified smoking habits as "non-smoker," "trier," "ex-smoker," and "smoker."^ The study presented the low rate of cigarette smoking habits among female students, compared to male students. Significant differences of smoking-related habits were found among those who had exemplar models for smoking habits; fathers, siblings and peers were their reference groups. Parental approval was found to be a significant factor associated with students' smoking habits. The awareness of health hazards, the perceptions of the influence of cigarette advertisement, and the attitudes toward the concerns of government in cigarette manufacturing were also factors associated with cigarette smoking habits of high school subjects. ^

MARITAL STATUS AND CARDIOVASCULAR RISK (SERUM, CHOLESTEROL, CIGARETTE, SMOKING, BLOOD, PRESSURE, SYSTOLIC)

There were three purposes of this study. The first was to describe the association between stable marital status and serum cholesterol, systolic blood pressure and cigarette smoking. The second purpose was to determine whether individuals who were married at one point and became widowed or divorced/separated had higher serum cholesterol, higher systolic blood pressure or were more likely to smoke prior to the change in marital status compared with individuals who did not change marital status. The third purpose was to determine whether the changes in marital status described above were related to increases in serum cholesterol or in cigarette smoking behavior. The rationale for the study was to determine whether previously reported associations between marital status categories and cardiovascular mortality may be mediated through higher values of risk correlates for cardiovascular disease among unmarried individuals.^ The study group selected for this dissertation was a sample from the Hypertension Detection and Follow-up Program (HDFP) population. The HDFP population was aged 30-69 years at the initial visit and included blacks and whites, males and females. The population was followed five years after the initial visit and periodic measurements of serum cholesterol, blood pressure and cigarette smoking behavior were obtained.^ Serum cholesterol was not associated with stable marital status category or with marital status prior to change. Changes in serum cholesterol were associated with marital status categories after change but the serum cholesterol values deceased rather than increased. Married individuals were shown to have higher serum cholesterol values compared with unmarried. Selection of the HDFP population may have influenced an ability to detect a significant association between marital status and serum cholesterol but it is doubtful that use of a general population would alter the direction of the association.^ Systolic blood pressure was significantly higher at the initial visit among unmarried white males and females compared with their married counterparts. No association between systolic blood pressure was found among black males or females. Those individuals who were married at the initial visit who experienced a change in marital status were found to have higher systolic blood pressure prior to the change in marital status. . . .

Practice and attitude differences in physician cigarette use: A study of prevalence, physicians' role, and smoking policy awareness in Dubai, UAE

The use of tobacco products ruins the health of millions of people around the world. On average, tobacco users die nearly seven years earlier than non-tobacco users. n1 Cigarette smoking is a particular concern in the developing countries of the Middle East and Gulf Cooperation Council (GCC) region where smoking prevalence is expected to increase. This is due to the tobacco industry's vigorous commercial and marketing activities. n3 Smoking prevalence among physicians is considered to be an effective indicator of a society's readiness to identify the smoking epidemic and its related health diseases. n4 There is a lack of detailed data on the smoking prevalence among healthcare professionals, particularly physicians, in the United Arab Emirates (UAE). This cross sectional study is the first to address smoking practices among physicians working at the Department of Health and Medical Services (DOHMS); in Dubai, UAE. ^ This study describes the cigarette smoking prevalence among DOHMS Physicians, physician attitudes towards tobacco use and tobacco bans; physician attitudes towards smoking cessation techniques (among smokers and non-smokers); and physician awareness of official anti-smoking policies. Data for the study was collected through the use of an adapted WHO standardized questionnaire, the Global Health Professionals Survey. The questionnaire was administered by the researcher to physicians (n=288) at their work place. Date was analyzed using the SPSS analytic software program. ^ Twelve percent of DOHMS physicians smoked cigarettes. Regardless of smoking status, the majority supported a tobacco ban in hospitals and public places, and a ban on tobacco advertising. There is a significant relationship between physician smoking status and discussing risks of tobacco use (p < 0.05). Non-smoking physicians reported spending more time with patients discussing hazards of smoking (p < 0.01). Non-smokers reported providing more counseling than their smoking colleagues. The majority of DOHMS physicians (63%) reported a lack of knowledge about 5As/ 5Rs. The majority of physicians also reported they are aware of hospital smoking policies that restrict smoking. Regardless of physician smoking status, DOHMS physicians are not very actively involved in smoking cessation activities. This cross sectional study is the first to address smoking programs, policies, and practices among physicians in Dubai, UAE. Findings support the need for increased physical smoking cessation training as well as the development of smoking cessation programs for tobacco control, and programs with a focus on physician participation in reducing tobacco and cigarette use among the general population.^

HABIT o cómo medir la subjetividad en la movilidad en transporte urbano

Tradicionalmente en los modelos de transporte, las variables explicativas de la elección modal del usuario se reducen a las variables objetivas (coste del transporte, tiempo de viaje, etc.). Sin embargo, la literatura más reciente reconoce que el perfil del usuario así como sus percepciones, influyen también en la elección modal. Por ello, antes de formular un modelo de demanda de transporte, es conveniente integrar factores más subjetivos (percepciones y actitudes) de los usuarios del sistema de transporte. Para evaluar dicha influencia se ha optado por realizar una encuesta en las nuevas estaciones de la línea 2 de Metro, al Sureste de Madrid. Será una manera de medir la consistencia de los hábitos cuando una nueva infraestructura de transporte como el Metro se pone en marcha. La toma de datos se realiza a través de encuestas de preferencias reveladas a los usuarios del nuevo Metro. Gracias a dicha encuesta se puede conocer el anterior modo de viaje utilizado por los usuarios para realizar el mismo trayecto, por lo que se dispone de datos para evaluar el cambio de modo. En concreto, el encuestado responde a preguntas sobre el motivo del viaje, la disponibilidad de vehículo propio y el motivo principal para cambiar de modo. La encuesta de movilidad realizada en la nueva infraestructura permite recoger para desarrollar una metodología capaz de estimar los efectos de shock e inercia del cambio modal. Este artículo utiliza modelos de elección discreta integrando variables cuantitativas (coste del viaje, por ejemplo) y cualitativas (motivo del cambio modal) para explicar la elección modal. Los primeros resultados muestran que los viajes obligados (trabajo y estudios) que antes del Metro se realizaban en coche, presentan poca resistencia al cambio.

Visual habit formation in monkeys with neurotoxic lesions of the ventrocaudal neostriatum

Visual habit formation in monkeys, assessed by concurrent visual discrimination learning with 24-h intertrial intervals (ITI), was found earlier to be impaired by removal of the inferior temporal visual area (TE) but not by removal of either the medial temporal lobe or inferior prefrontal convexity, two of TE's major projection targets. To assess the role in this form of learning of another pair of structures to which TE projects, namely the rostral portion of the tail of the caudate nucleus and the overlying ventrocaudal putamen, we injected a neurotoxin into this neostriatal region of several monkeys and tested them on the 24-h ITI task as well as on a test of visual recognition memory. Compared with unoperated monkeys, the experimental animals were unaffected on the recognition test but showed an impairment on the 24-h ITI task that was highly correlated with the extent of their neostriatal damage. The findings suggest that TE and its projection areas in the ventrocaudal neostriatum form part of a circuit that selectively mediates visual habit formation.

Island colonization and evolution of the insular woody habit in Echium L. (Boraginaceae).

Numerous island-inhabiting species of predominantly herbaceous angiosperm genera are woody shrubs or trees. Such "insular woodiness" is strongly manifested in the genus Echium, in which the continental species of circummediterranean distribution are herbaceous, whereas endemic species of islands along the Atlantic coast of north Africa are woody perennial shrubs. The history of 37 Echium species was traced with 70 kb of noncoding DNA determined from both chloroplast and nuclear genomes. In all, 239 polymorphic positions with 137 informative sites, in addition to 27 informative indels, were found. Island-dwelling Echium species are shown to descend from herbaceous continental ancestors via a single island colonization event that occurred < 20 million years ago. Founding colonization appears to have taken place on the Canary Islands, from which the Madeira and Cape Verde archipelagos were invaded. Colonization of island habitats correlates with a recent origin of perennial woodiness from herbaceous habit and was furthermore accompanied by intense speciation, which brought forth remarkable diversity of forms among contemporary island endemics. We argue that the origin of insular woodiness involved response to counter-selection of inbreeding depression in founding island colonies.

Reduction of tobacco smoke components yield in commercial cigarette brands by addition of HUSY, NaY and Al-MCM-41 to the cigarette rod

The effect of two zeolites, HUSY, NaY and a mesoporous synthesized Al-MCM-41 material on the smoke composition of ten commercial cigarettes brands has been studied. Cigarettes were prepared by mixing the tobacco with the three powdered materials, and the smoke obtained under the ISO conditions was analyzed. Up to 32 compounds were identified and quantified in the gas fraction and 80 in the total particulate matter (TPM) condensed in the cigarettes filters and in the traps located after the mouth end of the cigarettes. Al-MCM-41 is by far the best additive, providing the highest reductions of the yield for most compounds and brands analyzed. A positive correlation was observed among the TPM and nicotine yields with the reduction obtained in nicotine, CO, and most compounds with the three additives. The amount of ashes in additive free basis increases due to the coke deposited on the solids, especially with Al-MCM-41. Nicotine is reduced with Al-MCM-41 by an average of 34.4% for the brands studied (49.5% for the brand where the major reduction was obtained and 18.5 for the brand behaving the worst). CO is reduced by an average of 18.6% (ranging from 10.3 to 35.2% in the different brands).

Quand le tabac s’affiche au Parlement. Débats sur les limitations en matière de publicité de la cigarette dans les cantons romands

Cette contribution porte sur les politiques d’interdiction de la publicité pour les cigarettes, l’un des axes-clé de la prévention structurelle du tabagisme. Nous nous intéressons à la rapide et récente dissémination de ces politiques dans les cantons suisses, qui contraste avec l’immobilisme fédéral. Nous attirons alors l’attention sur le rôle moteur du niveau d’action cantonal, au sein d’un domaine de santé publique qui avait pourtant connu, cette dernière décennie, ses plus formidables avancées dans le sillage de mouvements d’essence supranationaux. L’analyse des débats parlementaires romands nous permet finalement d’élaborer une typologie des argumentaires en présence, et de mettre en évidence les axes les plus à mêmes de provoquer une scission gauche/droite.
