There is a lack of information on how cognitive ability relates to both health behaviors and change in health behaviors over time. This study examined verbal ability and processing speed as predictors of health behaviors in the PATH Through Life Study that includes cohorts aged in their 20s, 40s and 60s. Higher cognitive scores were associated with higher levels of physical activity, greater likelihood of taking vitamin and mineral supplements, reduced likelihood of current smoking and not abstaining from alcohol. However, lower level of verbal ability and processing speed were associated with higher levels of use of cholesterol lowering medication in the 60s cohort. Physical activity, consumption of vitamins and minerals and taking cholesterol lowering and antihypertensive medication over the four-year follow-up period increased in this cohort. The likelihood of adopting healthier behaviors was greatest for those with the lowest cognitive scores. We conclude that while higher levels of cognitive performance are associated with health promoting behaviors, improvements in health behavior are more likely to be due to non-cognitive, contextual and societal factors.  相似文献

There has been discussion over the extent to which delay discounting – as prototypically shown by a preference for a smaller-sooner sum of money over a larger-later sum – measures the same kind of impulsive preferences that drive non-financial behavior. To address this issue, a dataset was analyzed containing 42,863 participants’ responses to a single delay-discounting choice, along with self-report behaviors that can be considered as impulsive. Choice of a smaller-sooner sum was associated with several demographics: younger age, lower income, and lower education; and impulsive behaviors: earlier age of first sexual activity and recent relationship infidelity, smoking, and higher body mass index. These findings suggest that at least an aspect of delay discounting preference is associated with a general trait influencing other forms of impulsivity, and therefore that high delay discounting is another form of impulsive behavior.  相似文献

In English-speaking, Western-Anglo countries, where smoking has become stigmatized in recent decades as a result of widespread anti-smoking campaigns, smokers commonly report poorer psychological health on average than nonsmokers do. This may be indirectly related to the strong pressures to quit in such countries, as poorer psychological health is associated with a reduced likelihood of quitting, thus leading to a selection bias for smokers with relatively poorer psychological health. In the present study, 147 smoker and nonsmoker participants either came from Western-Anglo countries where smoking has become stigmatized (Australia, Canada, USA) or countries in regions where smoking remains relatively more accepted (Asia, Latin America, Europe). Smokers and nonsmokers were assessed on a widely used self-report measure of anxiety, depression, and stress. Multivariate analysis revealed a significant interaction between smoker status (smoker, nonsmoker) and country of origin (Western-Anglo, other) on psychological health ratings, with univariate analysis showing a significant interaction on anxiety scores. Among those from Western-Anglo countries, smokers reported significantly higher levels of anxiety than nonsmokers did, whereas there was no difference in anxiety between smokers and nonsmokers from other countries. There was no difference in the number of cigarettes smoked per day between the samples of smokers, indicating very similar levels of nicotine intake in the two groups. The findings support the notion that a selection bias for smokers with relatively poorer psychological health is occurring in Western-Anglo countries.  相似文献

Discrimination has been conceptualized as a stressor that may be more negative than generic stress because it is tied to valued and unchangeable social identities. As with other stressful events, the experience of sexism has been related to poorer mental health and some physical health outcomes. This study of 179 female college students (79% of whom were White) showed that the relation between perceived sexism and binge drinking and smoking was mediated by psychological distress. In addition, there was a direct relation between sexism and smoking for weight control. Given the large toll that tobacco and excessive alcohol use exact on the U.S. population, we suggest that policy makers aim to reduce discrimination as one method to improve overall health.  相似文献

The risk of tobacco use during adolescence may be traced back to early childhood, the time when a child is most vulnerable to environmental influence. We examined daily-life enrichment during pre-kindergarten period as a predictor of initiation of cigarette smoking among Asian American and Hispanic/Latino children during adolescence. Survey data were collected from students in grades seven to nine in California. Among the 2,719 participants who completed the survey, 37% were Asian American and 44% were Hispanic/Latino. Five aspects of childhood life before kindergarten were assessed, including having lots of toys for the child, parents' read to the child often, having a plenty of good food for the child, bringing the child to travel, and parents spending adequate time with the child. Findings from our research indicate that children with more enriched early childhood are less likely to start smoking during adolescence. Consequently, enhancing daily life during early childhood may represent a new strategy for adolescent smoking prevention.  相似文献

Background/Objective: Despite the fact that electronic cigarettes, or e-cigarettes, are being increasingly used as an alternative to smoking tobacco cigarettes, few studies have explored psychological factors associated with e-cigarette use. Prior studies aimed at exploring correlates of e-cigarette use have focused on sociodemographic and smoking-related characteristics. However, no previous work has examined psychological features such as impulsivity among e-cigarettes users. The main objective of this study was to compare impulsivity rates across four groups of participants: current e-cigarette users who were former smokers; current smokers; former smokers; and controls. Method: A sample of 136 participants completed a computerized delay discounting task for hypothetical monetary values. Results: Delay discounting was greater among e-cigarette users than former smokers. E-cigarette users also showed an intermediate discounting that did not differ from smokers and controls. Moreover, delay discounting was significantly greater among current smokers compared to former smokers and controls. Conclusions: Taken together, our results extend previous research on delay discounting by providing evidence on impulsivity levels among current e-cigarette users for the first time.  相似文献

Many smokers and ex-smokers worry about their health. Given that worry keeps attention focused on the threat, it was expected that worrying about health in smokers would motivate them to quit and in ex-smokers may prevent relapse. Furthermore, worry was expected to influence the process of smoking cessation in interaction with self-efficacy, which is a measure of control over smoking, and with disengagement beliefs, which distorts the threatening meaning of potential motivating information. In the present study 380 smokers and 324 ex-smokers were recruited to join a prospective study with a follow-up of eight months. At T1, smoking/quitting behavior, worry and the other psychological constructs were assessed. At T2 quitting activity in smokers and relapse in ex-smokers were assessed. As expected, smokers who worried about the health effects of smoking reported higher quitting activity at T2. The three-way interactions between worry, self-efficacy and disengagement beliefs in the prospective prediction of quitting activity and relapse were significant: Among smokers with high self-efficacy combined with strong disengagement beliefs, worry led to more quitting activity. Among ex-smokers with low self-efficacy combined with strong disengagement beliefs, worry led to more relapse. The present results suggest new ways of approaching the stimulation of quitting and the prevention of relapse.  相似文献

Although previous work has found associations between panic and smoking, little research has investigated potential mechanisms by which smoking may contribute to panic problems. The present investigation evaluated the incremental validity of acute nicotine withdrawal symptoms (elicited by an average of 2 h of nicotine deprivation) relative to negative affectivity, anxiety sensitivity, and nicotine dependence in predicting anxiety responding to 3-min voluntary hyperventilation. The sample consisted of 90 regular smokers (46 females), as defined by smoking 10 cigarettes per day for at least 1 year, recruited through the general community. Consistent with prediction, greater levels of pre-challenge nicotine withdrawal symptoms uniquely predicted post-challenge intensity of panic symptoms and anxiety relative to other established factors. Findings are discussed in the context of how regular smoking may promote panic symptomotology.  相似文献

PurposeLimited 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.MethodsRegression 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.ResultsNo 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.ConclusionBecause 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.  相似文献
