Although lower socioeconomic status has been linked to increased youth substance use, much less research has determined potential mechanisms explaining the association. The current longitudinal study tested whether alternative (i.e.

Yet, research elucidating cognitive-affective vulnerability characteristics that contribute to increased tobacco withdrawal severity during periods of planned abstinence is highly limited. In the current study, we explored whether smokers with greater reductions of Anxiety Sensitivity (AS) and dysphoria during a smoking cessation intervention would experience less severe postquit tobacco withdrawal.

The present study examined relations between the extent of change in anxiety sensitivity and the course of nicotine withdrawal symptoms experienced during the initial two weeks of a quit attempt among treatment-seeking smokers. The sample consisted of 29 adult daily smokers (34% female; M = 47.

Positive emotional traits may function as coping factors that buffer the extent to which dependence increases vulnerability to adverse responses to acute tobacco abstinence (ie, tobacco withdrawal). This laboratory study examined subjective happiness (SH; dispositional orientation towards frequent and intense positive affect [PA] and life satisfaction) as a moderator of the relation between tobacco dependence and subjective and behavioral abstinence effects among AA smokers.

Objective: To evaluate whether use of e-cigarettes with higher nicotine concentrations is associated with subsequent increases in the frequency and intensity of combustible cigarette smoking and vaping.
Objective: Research indicates that children are at higher risk for obesity if their parents have been exposed to a larger number of stressors, yet little is known about effects of parents' subjective, perceived experience of stress on children's eating behaviours and adiposity and whether weight-related parenting practices (i.e. parent rules and positive family meal practices) mediate this relationship.

This randomized placebo-controlled laboratory study tested the independent and interactive effects of intra-individual ovarian hormone variation and nicotine on suppression of tobacco withdrawal symptoms and smoking behavior. Female smokers randomized to 21 mg nicotine (TNP; n=37) or placebo (PBO; n=43) transdermal patch following overnight abstinence completed three sessions occurring during hormonally distinct menstrual cycle phases.

ECIG nicotine emission is determined, in part, by user behavior, liquid nicotine concentration, and electrical power. Whether users are able to report accurately nicotine concentration and device electrical power has not been evaluated.

In tobacco literature, the Smoking Consequences Questionnaire (SCQ; Brandon & Baker, 1991) is a tool used to assess this construct. Despite its common use, the SCQ has received little psychometric evaluation.

It is unclear whether this association: (1) extends to alternative tobacco products, like electronic cigarettes and hookah (tobacco water pipe), which are increasingly popular among youth, and (2) differs by gender. In this report, data were drawn from a population-based longitudinal cohort of youth in Southern California.

Free medical-care is provided by two walk-in clinics in Tel-Aviv. This study aims to compare the medical complaints of UM from different origins, define their community health needs and assess gaps between medical needs and available services.

Premenstrual symptoms (PMS) may reduce smoking cessation success. Yet, little is known about the factors that may impact smoking cessation among women with elevated PMS, leaving little data to guide smoking cessation science and practice for this population. This cross-sectional study is a secondary analysis of data from laboratory studies focused on menstrual cycle effects and smoking.

Objective: To perform a systematic review and meta-analysis of longitudinal studies that assessed initial use of e-cigarettes and subsequent cigarette smoking.
Data Sources: PubMed, EMBASE, Cochrane Library, Web of Science, the 2016 Society for Research on Nicotine and Tobacco 22nd Annual Meeting abstracts, the 2016 Society of Behavioral Medicine 37th Annual Meeting & Scientific Sessions abstracts, and the 2016 National Institutes of Health Tobacco Regulatory Science Program Conference were searched between February 7 and February 17, 2017.
Background And Aims: Anhedonia-a transdiagnostic psychopathological trait indicative of inability to experience pleasure-could lead to and result from adolescent marijuana use, yet this notion has not been tested. This study aimed to estimate the association of: (1) anhedonia at age 14 with rate of change in marijuana use over an 18-month follow-up, and (2) marijuana use at age 14 with rate of change in anhedonia over follow-up. Secondary aims were to test whether gender, baseline marijuana use history and peer marijuana use moderated these associations.

Data were drawn from a longitudinal study of high school students in Los Angeles, CA, USA who completed surveys and reported past six-month use of alcohol (n=1054), cigarettes (n=297), or cannabis (n=706). At each of the four semi-annual waves during mid-adolescence (14-16years old), students reported positive and negative subjective drug effects experienced in the prior six-months.

The role of anhedonia in adolescent smoking uptake has largely been uninvestigated, leaving unclear whether anhedonia is associated with smoking initiation and with psychosocial determinants of susceptibility to smoking initiation that could be targeted in prevention. This study examined the association of anhedonia with smoking initiation (ever smoke: yes/no) and factors indicative of susceptibility to smoking initiation among never-smokers (smoking outcome expectancies, curiosity about smoking, and willingness and future intention to initiate smoking).

It is now possible to remove right-sided vegetations percutaneously using a venous drainage cannula with an extracorporeal bypass circuit.
Objectives: The purpose of our study is to describe our single-center experience of percutaneous tricuspid valve vegetation removal.
Background: Physical activity and diet are major modifiable health behaviors contributing to obesity risk. Although patterns of these behaviors tend to cluster within individuals and within family units, it is unknown to what extent healthy and unhealthy dietary intake might differentially accompany sedentary and physical activities in mothers compared with their children.
Objective: Our goal was to examine differences in co-occurrence of activities and dietary intake between mothers and children, as measured in real time using ecological momentary assessment.
Background: A recent study of adult smokers who vape found that disposable/cigalike electronic (e-) cigarette devices were more commonly used than later generation devices. However, whether these trends reflect patterns among adolescents and young adults, many of whom have limited or no history of combustible cigarette use, has not been studied.
Methods: Participants were drawn from eight locally, regionally, and US nationally representative studies.
Low adherence to guidelines for weight-related behaviours (e.g. dietary intake and physical activity) among US children underscores the need to better understand how parental factors may influence children's obesity risk.

This laboratory study sought to identify motivational mechanisms linking anhedonia and tobacco addiction by testing the hypothesis that anhedonia, abstinence, and their interaction would predict excesses and deficits in the perceived pleasantness of smoking-related and positive pictures, respectively. We assessed the pleasantness of negative pictures as a secondary outcome.
