Effectiveness of mindfulness based cognitive therapy on weight loss, improvement of hypertension and attentional bias to eating cues in overweight people.

ABSTRACT: Objectives:Prevalence rates of overweight and obesity are dramatically ever-increasing across the world. Therefore, this study was to evaluate the effect of mindfulness-based cognitive therapy (MBCT) on weight loss, hypertension, and attentional bias towards food cues in a group of women affected with this condition. Methods:A total of 45 participants were selected out of women referring to the Nutrition and Diet Therapy Clinic affiliated to Shahid Beheshti University of Medical Sciences, Iran, and then randomized into three groups of 15. The first experimental group was subjected to an energy-restricted diet therapy together with MBCT during 8 sessions, the second group took the diet therapy alone, and the third group received no intervention. Body mass index (BMI), hypertension, and attentional bias towards food cues were correspondingly evaluated before, at the end, and four weeks after the completion of the interventions. Results:The results of this study revealed that MBCT, along with diet therapy, had been significantly more effective in weight loss, decrease in BMI, lower systolic blood pressure (SBP), and attentional bias towards food cues compared with the diet therapy alone (P ? 0.01). MBCT had no significant impact on the decline in diastolic blood pressure (DBP) in participants in the follow-up phase. Conclusion:This study demonstrated that MBCT along with the conventional diet therapy was more effective in weight loss, decrease in BMI, hypertension control, as well as attentional bias towards food cues than the diet therapy alone.

Project description:BACKGROUND AND AIMS:Cannabidiol (CBD), a non-intoxicating cannabinoid found in cannabis, may be a promising novel smoking cessation treatment due to its anxiolytic properties, minimal side effects and research showing that it may modify drug cue salience. We used an experimental medicine approach with dependent cigarette smokers to investigate if (1) overnight nicotine abstinence, compared with satiety, will produce greater attentional bias (AB), higher pleasantness ratings of cigarette-related stimuli and increased craving and withdrawal; and (2) CBD in comparison to placebo, would attenuate AB, pleasantness of cigarette-related stimuli, craving and withdrawal and not produce any side effects. DESIGN:Randomized, double-blind cross-over study with a fixed satiated session followed by two overnight abstinent sessions. SETTING:UK laboratory. PARTICIPANTS:Thirty non-treatment-seeking, dependent cigarette smokers recruited from the community. INTERVENTION AND COMPARATOR:800 mg oral CBD, or matched placebo (PBO) in a counterbalanced order MEASUREMENTS: AB to pictorial tobacco cues was recorded using a visual probe task and an explicit rating task. Withdrawal, craving, side effects, heart rate and blood pressure were assessed repeatedly. FINDINGS:When participants received PBO, tobacco abstinence increased AB (P = 0.001, d = 0.789) compared with satiety. However, CBD reversed this effect, such that automatic AB was directed away from cigarette cues (P = 0.007, d = 0.704) and no longer differed from satiety (P = 0.82). Compared with PBO, CBD also reduced explicit pleasantness of cigarette images (P = 0.011; d = 0.514). Craving (Bayes factor = 7.08) and withdrawal (Bayes factor = 6.95) were unaffected by CBD, but greater in abstinence compared with satiety. Systolic blood pressure decreased under CBD during abstinence. CONCLUSIONS:A single 800-mg oral dose of cannabidiol reduced the salience and pleasantness of cigarette cues, compared with placebo, after overnight cigarette abstinence in dependent smokers. Cannabidiol did not influence tobacco craving or withdrawal or any subjectively rated side effects.

Project description:People vary in the frequency with which they worry and there is large variation in the degree to which this worry disrupts their everyday functioning. Heightened tendency to experience disruptive worry is characterised by an attentional bias towards threat. While this attentional bias is often considered maladaptive, it can be adaptive when it concerns threat cues signalling dangers that can be mitigated through personal action. In this case, the resulting worry may increase the likelihood of this action being taken, with beneficial rather than disruptive consequences for everyday functioning. Thus, depending on its focus, attentional bias to threat could potentially drive worry that is high or low in disruptiveness. The current study addressed this possibility, by testing the novel hypothesis that the degree to which worry is disruptive is a function of the degree to which this attentional bias concerns all threat cues, rather than being restricted to threat cues signalling controllable dangers. Participants completed a novel probe task assessing their attention to threat cues signalling a future danger that could be controlled on some blocks, but not on others. Thus, the task revealed the degree to which their selective attention to threat cues was 'aligned' with danger controllability, by being more evident on blocks that permitted participant control of the danger signalled by the threat cues. The results indicate, contradicting the hypothesis under test, participants who reported high levels of disruptive worry demonstrated alignment of attentional bias to variations in danger controllability, whereas this was not the case for participants who reported high levels of non-disruptive worry. While caution is needed in the interpretation of the results due to methodological limitations, this study provides a new conceptual and methodological framework for future research on the attentional basis of individual differences in the tendency to experience disruptive vs non-disruptive worry.
