    Pharmacological and non-pharmacological smoking motives: a replication and extension

    Full text link
    Cigarette smokers (n = 387) completed a questionnaire measure of smoking motives, and subgroups of this sample provided external validation information. Seven factors emerged from a principal components’analysis: automatic, sedative, addictive, stimulation, psychosocial, indulgent and sensorimotor manipulation. A higher-order principal components analysis revealed the presence of two second-order factors. Inspection of the pattern of correlations between factor scores and criterion variables clearly indicated that the first four factors above and their underlying second-order factor are more closely related to nicotine pharmacology and mood-altering effects of nicotine than the latter three motives and their underlying second-order factor. Moreover, the positive correlations between these pharmacological motives and age, coupled with a negative relationship between age and the non-pharmacological motives, support the description of the smoking career as a progressive transfer of reward from non-pharmacological to pharmacological factors. These findings suggest that self-reported reasons for smoking represent more than bias in verbal report.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/75075/1/j.1360-0443.1994.tb00899.x.pd

    Temporal stability and within-subject consistency of nicotine withdrawal symptoms

    Full text link
    This study tested the temporal stability and within-subject consistency of the Diagnostic and Statistical Manual-III-R (DSM-III-R) nicotine withdrawal symptoms in 39 (21 female, 18 male) regular smokers. Subjects provided withdrawal symptom ratings while smoking ad libitum and during two 48-hour abstinence periods that were separated by 1 week. All but two symptoms, increased eating and hunger, demonstrated adequate temporal stability (i.e., stability coefficients >= .70). Within-subject consistency was found for impatience, anxiety, difficulty concentrating, and irritability. The total (average) score emerged as the most stable and consistent indicator of withdrawal. Results of a cluster analysis suggest the presence of two groups of smokers based on the withdrawal experience. Possible reasons for variability in nicotine withdrawal symptom reports are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31078/1/0000755.pd

    Research on stress and smoking: progress and problems

    Full text link
    Despite evidence that smoking behaviour increases in the context of stress, there has yet to be a clear-cut demonstration that nicotine intake is similarly enhanced. Although nicotine intake has been shown to reduce reported anxiety in the context of stress, the controlling conditions (type of stressor, intensity, temporal relationships, etc.) need further exploration. Recent findings involving nicotine's effects on the hypophyseal-adrenal axis provide a new perspective on these issues, in that increased nicotine intake during exposure to a stressor may represent, at least in part, behavioral compensation for diminished sensitivity to nicotine brought about by nicotine-stimulated corticosteroid release. Corticosteroids may decrease central nervous system excitability in a way that could account for anxiety reduction; on the other hand, anxiety reduction may be an epiphenomenon with respect to the reinforcement of smoking behaviour. The integration of behavioural, physiological, and biochemical research exemplified by the above approach should lead to a better understanding of stress and smoking.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73317/1/j.1360-0443.1991.tb01815.x.pd

    Three-dimensional imaging and detection efficiency performance of orthogonal coplanar CZT strip detectors

    We report on recent three-dimensional imaging performance and detection efficiency measurements obtained with 5 mm thick prototype CdZnTe detectors fabricated with orthogonal coplanar anode strips. In previous work, we have shown that detectors fabricated using this design achieve both very good energy resolution and sub-millimeter spatial resolution with fewer electronic channels than are required for pixel detectors. As electron-only devices, like pixel detectors, coplanar anode strip detectors can be fabricated in the thickness required to be effective imagers for photons with energies in excess of 500 keV. Unlike conventional double-sided strip detectors, the coplanar anode strip detectors require segmented contacts and signal processing electronics on only one surface. The signals can be processed to measure the total energy deposit and the photon interaction location in three dimensions. The measurements reported here provide a quantitative assessment of the detection capabilities of orthogonal coplanar anode strip detectors

    Access to water in the countries of the former Soviet Union.

    No full text
    BACKGROUND: During the Soviet period, authorities in the USSR invested heavily in collective farming and modernization of living conditions in rural areas. However, many problems remained, including poor access to many basic amenities such as water. Since then, the situation is likely to have changed; economic decline has coincided with migration and widening social inequalities, potentially increasing disparities within and between countries. AIM: To examine access to water and sanitation and its determinants in urban and rural areas of eight former Soviet countries. METHODS: A series of nationally representative surveys in Armenia, Belarus, Georgia, Moldova, Kazakhstan, Kyrgyzstan, Russia and Ukraine was undertaken in 2001, covering 18,428 individuals (aged 18+ years). RESULTS: The percentage of respondents living in rural areas varied between 27 and 59% among countries. There are wide urban-rural differences in access to amenities. Even in urban areas, only about 90% of respondents had access to cold running water in their home (60% in Kyrgyzstan). In rural areas, less than one-third had cold running water in their homes (44% in Russia, under 10% in Kyrgyzstan and Moldova). Between one-third and one-half of rural respondents in some countries (such as Belarus, Kazakhstan and Moldova) obtained their water from wells and similar sources. Access to hot running water inside the homes was an exception in rural households, reflecting the lack of modern heating methods in villages. Similarly, indoor access to toilets is common in urban areas but rare in rural areas. Access to all amenities was better in Russia compared with elsewhere in the region. Indoor access to cold water was significantly more common among rural residents living in apartments, and in settlements served by asphalt roads rather than dirt roads. People with more assets or income and living with other people were significantly more likely to have water on tap. In addition, people who had moved in more recently were more likely to have an indoor water supply. CONCLUSIONS: This was the largest single study of its kind undertaken in this region, and demonstrates that a significant number of people living in rural parts of the former Soviet Union do not have indoor access to running water and sanitation. There are significant variations among countries, with the worse situation in central Asia and the Caucasus, and the best situation in Russia. Access to water strongly correlates with socio-economic characteristics. These findings suggest a need for sustained investment in rebuilding basic infrastructure in the region, and monitoring the impact of living conditions on health

    ‘‘Healthy,’’ ‘‘diet,’’ or ‘‘hedonic’’ : how nutrition claims affect food-related perceptions and intake?

    The main purpose of this study was to investigate the impact of nutrition claims on food perceptions and intake among adult men and women, during ad libitum snacks. In a three (healthy vs. diet vs. hedonic) by two (normal-weight vs. overweight/obese) by two (unrestrained vs. restrained eaters) factorial design, 164 men and 188 women were invited to taste and rate oatmeal-raisin cookies. Despite the fact that the cookies were the same in all conditions, they were perceived as being healthier in the “healthy” condition than in the “diet” and “hedonic” conditions. The caloric content was estimated as higher by participants in the “hedonic” than in the “healthy” condition, by women than by men, and by restrained than by unrestrained eaters. Although measured ad libitum cookie intake did not differ as a function of experimental condition, overweight restrained men ate more than did women from each BMI and restraint category. Conversely, overweight restrained women ate less than did men from each BMI and restraint category. In conclusion, our manipulations of healthiness and “fatteningness” of food were effective in changing perceptions, but were not in changing behavior

    The female weight-control smoker: A profile

    Full text link
    Hypothesizing the existence of a subgroup of female smokers for whom nicotine masks, and abstinence unmasks, a tendency toward hyperphagia and perhaps even subthreshold disordered eating, we compared female "weight-control smokers" (WC; n = 46) and "non-weight-control smokers" (NWC; n = 52) on smoking- and eating-related variables. We also examined the relationship between weight-control smoking and withdrawal symptomatology during 48-hours of nicotine abstinence (n = 23). Although WC were not more depressed, anxious, or nicotine-dependent than NWC, they were significantly more likely to report weight gain and increased hunger during abstinence; they also scored higher on Cognitive Restraint and Disinhibition (Three-Factor Eating Questionnaire). The expected correlation of cotinine with weight emerged for NWC but not for WC. Weight-control smoking correlated with increased eating during abstinence. Our findings suggest that WC use dietary restraint as well as smoking to manage weight, and that abstinence may precipitate episodes of disinhibited or binge eating. If WC overinclude women vulnerable to excess or unpredictable eating and consequently to substantial weight gain that can be managed by nicotine, highly focused treatment strategies may be helpful.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31081/1/0000758.pd

    Controlled dosing of nicotine via an I ntranasal N icotine A erosol D elivery D evice (INADD)

    The present report describes an I ntranasal N icotine A erosol D elivery D evice (INADD) employing an artist's airbrush as aerosolizer and precise, electromechanical control of spray duration. It was designed for the administration of controlled doses of nicotine in a laboratory setting and has been used successfully in over 30 smokers and nonsmokers of both genders. In the present study, nicotine was administered to 12 male smokers at three different doses (0.05 mg, 1.00 mg, and 2.00 mg), and at the same dose (1 mg) on three different occasions. The low dose produced a minimal change in plasma nicotine, while the high dose produced a peak increment of around 16 ng/ml. The medium dose reliably produced a peak increment of around 8–9 ng/ml on all three occasions. Nicotine in plasma showed a sharp rise followed by a slower decline, mimicking the pattern associated with cigarette smoking. Physiological and biochemical responses showed significant dose-response relationships. Subjective reports suggested that aerosol dosing was somewhat aversive, but it is unclear whether this effect is intrinsic to the method or due to other factors. The device described in this report answers the need for a safe and easy means of controlling nicotine dose. Moreover, since nicotine administration via aerosol is novel for both smokers and non-smokers, minimizing the contributions of behavioral tolerance and habituation to the dosing vehicle, it lends itself to the comparison of the pharmacological effects of nicotine between experienced and naive subjects.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46339/1/213_2005_Article_BF02247431.pd
