RESUMO

Obesity is a chronic and multifactorial disease, with growing rates in the last 50 years worldwide, reaching pandemic levels. It is a major public health problem and is difficult to treat. Different approaches have been used to improve this scenario, including mindfulness-based interventions to enhance dietary behaviour and nutritional status. We compared the effectiveness of a 10-week mindful eating programme with that of a 10-week mindfulness programme and of a no-treatment control group. The sample was composed of adult, low-income women with a body mass index (BMI) ≥ 25 to < 40 receiving primary health care in São Paulo, Brazil. The participants (n = 284) were randomised into 3 groups: the control, mindfulness, and mindful eating. We took anthropometric and body composition measurements, applied psychometric measures, and performed biochemical tests at pre-intervention, post-intervention, and after 3 months. We estimated the regression coefficients among the analysis of adherent participants (per protocol: PP) and among those of all participants randomised to treatment (intention-to-treat: ITT) in addition to multiple imputation (MI). Both groups showed improvement in eating behaviour and reduction of binge eating both in the post-intervention and follow-up periods, but without significant changes in weight or most of the biological tests. Those in the mindful eating programme performed slightly better than those in the mindfulness and control groups in terms of improving eating behaviour and reducing binge eating among low-income overweight women.

RESUMO

Background: Worldwide, approximately 95% of obese people who follow diets for weight loss fail to maintain their weight loss in the long term. To fill this gap, mindfulness-based interventions, with a focus on mindful eating, are promising therapies to address this challenging public health issue. Aim: To verify the effects of the Mindfulness-Based Eating Awareness Training (MB-EAT) protocol by exploring quantitative and qualitative data collected from Brazilian women. Methods: A single-group, mixed-methods trial was conducted at a public university with adult women (n = 34). Four MB-EAT groups were offered weekly for 2.5-h sessions over 12 weeks. Pre- and post-intervention assessments included body mass index (BMI) and self-report measures of anxiety, depression, mindfulness, self-compassion, and eating behaviour. Qualitative information was collected using focus groups in the last session of each group, including both participants and MB-EAT instructors. The qualitative data were examined using thematic analyses and empirical categories. Results: Twenty participants (58.8%) completed both pre- and post-intervention assessments, with adequate attendance (≥4 sessions). There was a significant average decrease in weight of 1.9 ± 0.6 kg from pre- to post-intervention. All participants who had scored at the risk level for eating disorders on the EAT-26 decreased their score below this risk level. Qualitative analysis identified that participants were able to engage a more compassionate perspective on themselves, as well as greater self-awareness and self-acceptance. Conclusion: The MB-EAT showed preliminary efficacy in promoting weight loss and improvements in mindfulness and eating behaviour. This intervention promoted effects beyond those expected, extending to other life contexts.

RESUMO

OBJECTIVE: People of color and lower socioeconomic groups have higher obesity prevalence, lose less weight compared with Whites and higher socioeconomic groups, and are underrepresented in randomized controlled trials of mindfulness-based interventions. We examined whether mindfulness approaches reduce disparities in weight loss interventions. METHODS: We analyzed data from a randomized controlled trial of 194 participants with obesity (41% participants of color, 36% without college degree) comparing a 5.5-month mindfulness-based weight loss intervention to an active-control with identical diet-exercise guidelines. We assessed attendance, 18-month attrition, and weight change at 6, 12, and 18 months by race/ethnicity and education level using linear mixed models, adjusting for baseline body mass index, age, and education or race/ethnicity, respectively. RESULTS: Participants without versus with a college degree attended fewer sessions and had higher attrition across interventions. Participants of color attended fewer intervention sessions in the mindfulness compared with the control intervention. Overall, participants of color lost significantly less weight at 12 and 18 months compared with Whites. However, during the 6- to 18-month maintenance period, we found an interaction of intervention arm, race/ethnicity, and time (p = .035), indicating that participants of color compared with Whites regained more weight in the control (0.33 kg/mo; p = .005) but not mindfulness intervention (0.06 kg/mo; p = .62). Participants without a college degree had greater initial weight loss in the mindfulness compared to control intervention from 0 to 6 months (-0.46 kg/mo; p = .039). CONCLUSIONS: Although disparities persist, mindfulness approaches may mitigate some racial/ethnic and socioeconomic differences in weight loss compared with conventional diet-exercise programs.Trial Registration: Clinicaltrials.gov registration: NCT00960414.

RESUMO

BACKGROUND: Pregnancy is a time of high risk for excessive weight gain, leading to health-related consequences for mothers and offspring. Theory-based obesity interventions that target proposed mechanisms of biobehavioral change are needed, in addition to simply providing nutritional and weight gain directives. Mindfulness training is hypothesized to reduce stress and non-homeostatic eating behaviors - or eating for reasons other than hunger or caloric need. We developed a mindfulness-based intervention for high-risk, low-income overweight pregnant women over a series of iterative waves using the Obesity-Related Behavioral Intervention Trials (ORBIT) model of intervention development, and tested its effects on stress and eating behaviors. METHODS: Overweight pregnant women (n = 110) in their second trimester were enrolled in an 8-week group intervention. Feasibility, acceptability, and facilitator fidelity were assessed, as well as stress, depression and eating behaviors before and after the intervention. We also examined whether pre-to-post intervention changes in outcomes of well-being and eating behaviors were associated with changes in proposed mechanisms of mindfulness, acceptance, and emotion regulation. RESULTS: Participants attended a mean of 5.7 sessions (median = 7) out of 8 sessions total, and facilitator fidelity was very good. Of the women who completed class evaluations, at least half reported that each of the three class components (mindful breathing, mindful eating, and mindful movement) were "very useful," and that they used them on most days at least once a day or more. Women improved in reported levels of mindfulness, acceptance, and emotion regulation, and these increases were correlated with reductions in stress, depression, and overeating. CONCLUSIONS: These findings suggest that in pregnant women at high risk for excessive weight gain, it is both feasible and effective to use mindfulness strategies taught in a group format. Further, increases in certain mindfulness skills may help with better management of stress and overeating during pregnancy. TRIAL REGISTRATION: ClinicalTrials.gov NCT01307683 , March 8, 2011.

RESUMO

We evaluated changes in mindful eating as a potential mechanism underlying the effects of a mindfulness-based intervention for weight loss on eating of sweet foods and fasting glucose levels. We randomized 194 obese individuals (M age = 47.0 ± 12.7 years; BMI = 35.5 ± 3.6; 78% women) to a 5.5-month diet-exercise program with or without mindfulness training. The mindfulness group, relative to the active control group, evidenced increases in mindful eating and maintenance of fasting glucose from baseline to 12-month assessment. Increases in mindful eating were associated with decreased eating of sweets and fasting glucose levels among mindfulness group participants, but this association was not statistically significant among active control group participants. Twelve-month increases in mindful eating partially mediated the effect of intervention arm on changes in fasting glucose levels from baseline to 12-month assessment. Increases in mindful eating may contribute to the effects of mindfulness-based weight loss interventions on eating of sweets and fasting glucose levels.

RESUMO

Many individuals with obesity report over eating despite intentions to maintain or lose weight. Two barriers to long-term weight loss are reward-driven eating, which is characterized by a lack of control over eating, a preoccupation with food, and a lack of satiety; and psychological stress. Mindfulness training may address these barriers by promoting awareness of hunger and satiety cues, self-regulatory control, and stress reduction. We examined these two barriers as potential mediators of weight loss in the Supporting Health by Integrating Nutrition and Exercise (SHINE) randomized controlled trial, which compared the effects of a 5.5-month diet and exercise intervention with or without mindfulness training on weight loss among adults with obesity. Intention-to-treat multiple mediation models tested whether post-intervention reward-driven eating and psychological stress mediated the impact of intervention arm on weight loss at 12- and 18-months post-baseline among 194 adults with obesity (BMI: 30-45). Mindfulness (relative to control) participants had significant reductions in reward-driven eating at 6 months (post-intervention), which, in turn, predicted weight loss at 12 months. Post-intervention reward-driven eating mediated 47.1% of the total intervention arm effect on weight loss at 12 months [ß = -0.06, SE(ß) = 0.03, p = .030, 95% CI (-0.12, -0.01)]. This mediated effect was reduced when predicting weight loss at 18 months (p = .396), accounting for 23.0% of the total intervention effect, despite similar weight loss at 12 months. Psychological stress did not mediate the effect of intervention arm on weight loss at 12 or 18 months. In conclusion, reducing reward-driven eating, which can be achieved using a diet and exercise intervention that includes mindfulness training, may promote weight loss (clinicaltrials.gov registration: NCT00960414).

RESUMO

We examine the efficacy of conventional cognitive behavioral therapy (CCBT) versus religiously integrated CBT (RCBT) in persons with major depression and chronic medical illness. Participants were randomized to either CCBT (n = 67) or RCBT (n = 65). The intervention in both groups consisted of ten 50-minute sessions delivered remotely during 12 weeks (94% by telephone). Adherence to treatment was similar, except in more religious participants in whom adherence to RCBT was slightly greater (85.7% vs. 65.9%, p = 0.10). The intention-to-treat analysis at 12 weeks indicated no significant difference in outcome between the two groups (B = 0.33; SE, 1.80; p = 0.86). Response rates and remission rates were also similar. Overall religiosity interacted with treatment group (B = -0.10; SE, 0.05; p = 0.048), suggesting that RCBT was slightly more efficacious in the more religious participants. These preliminary findings suggest that CCBT and RCBT are equivalent treatments of major depression in persons with chronic medical illness. Efficacy, as well as adherence, may be affected by client religiosity.

RESUMO

Overweight and obese individuals differ in their degree of hedonic eating. This may reflect adaptations in reward-related neural circuits, regulated in part by opioidergic activity. We examined an indirect, functional measure of central opioidergic activity by assessing cortisol and nausea responses to acute opioid blockade using the opioid antagonist naltrexone in overweight/obese women (mean BMI=31.1±4.8) prior to the start of a mindfulness-based intervention to reduce stress eating. In addition, we assessed indices of hedonic-related eating, including eating behaviors (binge eating, emotional eating, external eating, restraint) and intake of sweets/desserts and carbohydrates (Block Food Frequency); interoceptive awareness (which is associated with dysregulated eating behavior); and level of adiposity at baseline. Naltrexone-induced increases in cortisol were associated with greater emotional and restrained eating and lower interoceptive awareness. Naltrexone-induced nausea was associated with binge eating and higher adiposity. Furthermore, in a small exploratory analysis, naltrexone-induced nausea predicted treatment response to the mindfulness intervention, as participants with more severe nausea at baseline maintained weight whereas those with little or no nausea responses tended to gain weight. These preliminary data suggest that naltrexone-induced cortisol release and nausea may help identify individuals who have greater underlying food reward dependence, which leads to an excessive drive to eat. Future research is needed to confirm this finding and to test if these markers of opioidergic tone might help predict success in certain types of weight management programs.

RESUMO

Objective: This study tested whether a mindfulness-based intervention for obesity that included components aimed at emotion regulation and mindful eating improved psychological outcomes including stress, anxiety, positive emotion, and depression, during the intervention period and at longer-term follow-up. Methods: Adults with obesity (N=194) were randomized to a 5.5-month diet-exercise weight loss intervention with or without mindfulness training focused on emotion regulation and mindful eating. Participants completed self-report measures of mindfulness and psychological well-being, which were planned secondary outcomes, at baseline, mid-intervention (3 months), and at 6-, 12-, and 18-months post-baseline (maintenance period). Mixed effects models and linear regression were used to test between- and within-group changes in psychological well-being. Finally, this study explored whether changes in mindfulness (from baseline to each 6- and 18-months post-baseline) mediated the effects of intervention arm on changes in psychological outcomes during those respective time periods. This study explored whether changes in mindfulness from baseline to 6 months mediated the effects of intervention arm on changes in psychological outcomes from baseline to 18 months. Results: Participants randomized to the mindfulness arm had significant increases in positive emotions at all follow-up times compared to controls. There were statistically significant increases in mindfulness, psychological flexibility, and reflection, as well as decreases in anxiety and depressive symptoms at 12 months compared to control participants. These changes remained significant for psychological flexibility and reflection at 18 months. There were no significant differences in perceived stress. Among mindfulness participants, greater increases in mindfulness from 6-18 months was associated with greater positive emotions and psychological flexibility as well as lower perceived stress, anxiety, depressive symptoms, and rumination at 18 months, adjusting for 6-month values. Mediation analyses indicated that randomization to the mindfulness intervention arm was associated with 6-month increases in mindfulness, and these increases were in turn associated with improved psychological outcomes at 6 months and 18 months. Changes from baseline to 18 months did not mediate 18-month changes in psychological outcomes. Conclusions: Mindfulness training in emotion regulation and mindful eating may provide greater longer-term psychological well-being benefits in non-clinical populations with obesity compared to conventional diet-exercise interventions.

RESUMO

Higher levels of religious and spiritual engagement have been shown to be associated with better adjustment in dealing with serious illness. Nevertheless, the pattern of such engagement may vary substantially among individuals. This paper presents exploratory research with the goal of identifying subgroups of individuals with non-terminal cancer who vary along multiple dimensions of religious/spiritual (R/S) involvement and well-being. Cluster analysis utilized both R/S (FACIT-Sp) and quality of life variables (e.g., FACT-G) to identify subgroups within 114 individuals (Median age = 65; 59% female) under care for cancer. Additional R/S and adjustment variables were used to explore further distinctions among these groups. Four clusters were identified: High R/S (45%), with the lowest depression; Low R /High S (25%), also with good adjustment; Negative Religious Copers (14%), with the highest depression; and Low R/S (16%), with the poorest adjustment to cancer. The results support the value of differentiating patterns of religious and spiritual engagement in relation to well-being, with implications for matching psycho-social interventions with individuals.

RESUMO

This paper reviews the conceptual foundation of mindfulness-based eating awareness training (MB-EAT). It provides an overview of key therapeutic components as well as a brief review of current research. MB-EAT is a group intervention that was developed for treatment of binge eating disorder (BED) and related issues. BED is marked by emotional, behavioral and physiological disregulation in relation to food intake and self-identity. MB-EAT involves training in mindfulness meditation and guided mindfulness practices that are designed to address the core issues of BED: controlling responses to varying emotional states; making conscious food choices; developing an awareness of hunger and satiety cues; and cultivating self-acceptance. Evidence to date supports the value of MB-EAT in decreasing binge episodes, improving one's sense of self-control with regard to eating, and diminishing depressive symptoms.

RESUMO

OBJECTIVE: We aimed to understand the associations of compulsive eating (CE) and stress eating (SE) with metabolic health among adults with obesity and whether mindfulness-based weight loss training may buffer these associations. METHOD: We used data from a trial in which we randomized 194 participants with obesity to a diet-exercise weight loss intervention with either mindful eating training plus mindfulness-based eating awareness and stress management training (n = 100) or active control components (n = 94). We measured CE, SE, weight, and fasting blood glucose (FBG) at baseline, and 6, 12 months, and 18 months. We tested CE and SE as both moderators and mediators of intervention effects on changes in metabolic health. RESULTS: Participants higher (+ 1 SD) in CE at baseline randomized to the mindfulness (vs. control) intervention had greater improvements in FBG at 18 months (p = .05). Twelve-month reductions in CE mediated the effect of the intervention on changes in FBG and weight at 12 and 18 months postbaseline (p ≤ .05). Furthermore, those higher (+ 1 SD) in SE at baseline were nearly 2 BMI points higher than those lower (-1 SD) in SE (p < .01). Decreases in SE (B = 3.42; p < .001; 95% CI [2.55, 4.30]) and CE (B = 0.45; p < .001; 95% CI [0.36, 0.54]) in all participants at 6 months were associated with greater weight loss at 18 months. CONCLUSIONS: Those with greater compulsive eating may reduce risk for metabolic decline by participating in a mindfulness-based weight loss program. Future obesity interventions should consider tailoring treatment toward trait-level characteristics, such as compulsive eating. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

RESUMO

OBJECTIVE: Mindfulness-based interventions have been found to reduce psychological and physiological stress reactivity. In obesity, however, stress reactivity is complex, with studies showing both exaggerated and blunted physiological responses to stressors. A nuanced view of stress reactivity is the "challenge and threat" framework, which defines adaptive and maladaptive patterns of psychophysiological stress reactivity. We hypothesized that mindfulness training would facilitate increased challenge-related appraisals, emotions, and cardiovascular reactivity, including sympathetic nervous system activation paired with increased cardiac output (CO) and reduced total peripheral resistance (TPR) compared to a control group, which would exhibit an increased threat pattern of psychophysiological reactivity to repeated stressors. METHODS: Adults (N=194) with obesity were randomized to a 5.5-month mindfulness-based weight loss intervention or an active control condition with identical diet-exercise guidelines. Participants were assessed at baseline and 4.5 months later using the Trier Social Stress Task. Electrocardiogram, impedance cardiography, and blood pressure were acquired at rest and during the speech and verbal arithmetic tasks to assess pre-ejection period (PEP), CO, and TPR reactivity. RESULTS: Mindfulness participants showed significantly greater maintenance of challenge-related emotions and cardiovascular reactivity patterns (higher CO and lower TPR) from pre to post-intervention compared to control participants, but groups did not differ in PEP. Findings were independent of changes in body mass index. CONCLUSIONS: Mindfulness training may increase the ability to maintain a positive outlook and mount adaptive cardiovascular responses to repeated stressors among persons with obesity though findings need to be replicated in other populations and using other forms of mindfulness interventions.

RESUMO

OBJECTIVE: Although the relationship between religious practice and health is well established, the relationship between spirituality and health is not as well studied. The objective of this study was to ascertain whether participation in the mindfulness-based stress reduction (MBSR) program was associated with increases in mindfulness and spirituality, and to examine the associations between mindfulness, spirituality, and medical and psychological symptoms. METHODS: Forty-four participants in the University of Massachusetts Medical School's MBSR program were assessed preprogram and postprogram on trait (Mindful Attention and Awareness Scale) and state (Toronto Mindfulness Scale) mindfulness, spirituality (Functional Assessment of Chronic Illness Therapy--Spiritual Well-Being Scale), psychological distress, and reported medical symptoms. Participants also kept a log of daily home mindfulness practice. Mean changes in scores were computed, and relationships between changes in variables were examined using mixed-model linear regression. RESULTS: There were significant improvements in spirituality, state and trait mindfulness, psychological distress, and reported medical symptoms. Increases in both state and trait mindfulness were associated with increases in spirituality. Increases in trait mindfulness and spirituality were associated with decreases in psychological distress and reported medical symptoms. Changes in both trait and state mindfulness were independently associated with changes in spirituality, but only changes in trait mindfulness and spirituality were associated with reductions in psychological distress and reported medical symptoms. No association was found between outcomes and home mindfulness practice. CONCLUSIONS: Participation in the MBSR program appears to be associated with improvements in trait and state mindfulness, psychological distress, and medical symptoms. Improvements in trait mindfulness and spirituality appear, in turn, to be associated with improvements in psychological and medical symptoms.

RESUMO

In the Mindfulness-Based Eating Awareness Training program (MB-EAT) (Kristeller and Wolever, 2014; Kristeller and Wolever, in press), mindfulness practice is taught, mindful eating is cultivated, and self-acceptance and spiritual well-being are enhanced. An integrative concept is the value of cultivating 'wisdom' in regard to creating a new and sustainable relationship to eating and food. 'Wisdom' refers to drawing on personal experience and understanding in a flexible, insightful manner, rather than strictly following external rules and guidelines. Several clinical trials involving variations of MB-EAT have documented substantive improvement in how people relate to their eating, including individuals with both binge eating disorder (BED) and subclinical eating issues. Based on the traditional value of contemplative practices for cultivating spiritual engagement, and on evidence from related research showing that spiritual well-being increases in the Mindfulness-Based Stress Reduction (MBSR) program and is related to other effects, we hypothesized that the MB-EAT program would also engage this aspect of experience, as assessed by the Functional Assessment of Chronic Illness Therapy - Spiritual Well-Being subscale (FACIT-Sp), and that increases in spiritual well-being would relate to other measures of adjustment such as emotional balance and improvement in disordered eating. Participants (N = 117) with moderate to morbid obesity, including 25.6% with BED, were randomly assigned to MB-EAT or a wait-list control, and assessed on the FACIT-Sp and other measures at baseline, immediate post (IP), and 2-month followup (F/Up). Both FACIT-Sp factors [Meaning/Peace (M/P) and Faith] increased significantly in the MB-EAT group and were stable/decreased in the control group. Increases in these factors related to improvement in emotional adjustment and eating regulation at IP and at F/Up, and to increases in aspects of mindfulness measured by the Five Facet Mindfulness Questionnaire (FFMQ). Increases in M/P during treatment mediated effects of the FFMQ Observe factor on eating regulation and depression at IP. Results are discussed in terms of the role that mindfulness practice plays in cultivating 'wise mind' and the related value of spirituality. It is argued that the core elements of the MB-EAT program lead to meaningful spiritual engagement, which plays a role in people's ability to improve and maintain overall self-regulation.

RESUMO

BACKGROUND: Mindfulness has been applied in the United States and Europe to improve physical and psychological health; however, little is known about its feasibility and efficacy in a Brazilian population. Mindfulness may also be relevant in tackling obesity and eating disorders by decreasing binge eating episodes-partly responsible for weight regain for a large number of people-and increasing awareness of emotional and other triggers for overeating. The aim of the present study protocol is to evaluate and compare the feasibility and efficacy of two mindfulness-based interventions (MBIs) addressing overweight and obesity in primary care patients: a general programme called Mindfulness-Based Health Promotion and a targeted mindful eating protocol called Mindfulness-Based Eating Awareness Training. METHODS/DESIGN: A randomised controlled trial will be conducted to compare treatment as usual separately in primary care with both programmes (health promotion and mindful eating) added to treatment as usual. Two hundred forty adult women with overweight and obesity will be enrolled. The primary outcome will be an assessment of improvement in eating behaviour. Secondary outcomes will be (1) biochemical control; (2) anthropometric parameters, body composition, dietary intake and basal metabolism; and (3) levels of mindfulness, stress, depression, self-compassion and anxiety. At the end of each intervention, a focus group will be held to assess the programme's impact on the participants' lives, diet and health. A feasibility study on access to benefits from and importance of MBIs at primary care facilities will be conducted among primary care health care professionals and participants. Monthly maintenance sessions lasting at least 1 hour will be offered, according to each protocol, during the 3-month follow-up periods. DISCUSSION: This clinical trial will result in more effective mindfulness-based interventions as a complementary treatment in primary care for people with overweight and obesity. If the findings of this study confirm the effectiveness of mindfulness programmes in this population, it will be possible to improve quality of life and health while optimising public resources and reaching a greater number of people. In addition, on the basis of the evaluation of the feasibility of implementing this intervention in primary care facilities, we expect to be able to suggest the intervention for incorporation into public policy.

RESUMO

BACKGROUND: Childhood and adolescent overweight is one of the most important current public health concerns. There is an urgent need to initiate community-based prevention to support healthy eating and physical activity in children. Mindfulness-Based Eating Awareness Training (MB-EAT) is a 12-w eek manualized intervention developed by Kristeller et al. that uses focused meditation techniques to help obese individuals normalize eating behaviors, and improve exercise and dietary habits. OBJECTIVE: To adapt the MB-EAT program to adolescents (MB-EAT-A) and assess the impact of the MB-EAT-A program implemented in a high school setting on self-reported assessment of eating and exercise habits and dietary intake of fat. METHODS: 40 ninth grade adolescents (14 males; 35 African-Americans, 1 Caucasian, 4 Others; mean age 16.2±1.2 yrs; BMI=32.4±9.0, BMI range 19.1 to 58.4) from 6 high school health/physical education classes were randomly assigned to 12-weekly sessions of MB-EAT-A intervention (n=18) or health education control (CTL, n=22). Assessments of eating and exercise habits and dietary fat and caloric content were conducted at pre-test, post-test at 3 mo. immediately following intervention and follow-up, 3 months after intervention ended, with 85% retention at follow up. RESULTS: At 6 mo. follow-up, the MB-EAT-A group increased days/week of moderate exercise >30 min/day (0.8 vs -0.7 days/week), and intense aerobic exercise >20 min/day (1.4 vs. -0.5 days/week, both ps<.05) compared to decreases in CTLs. At 6 mo. follow-up the MB-EAT-A group increased number of servings per week of low calorie foods (7.7 vs. -.05, p<.02), foods with no saturated fats (5.1 vs. -0.4, p<.10) and low in saturated fats (4.6 vs. -2.7, p<.02). At 6 mo. follow-up the MBEAT-A group increased number of foods with no fat (3.9 vs -0.3, p<.08) and low in fat (5.8 vs. -1.4, p<.02) compared to decreases in CTLs. Weight gains at follow-up (4.2 vs 6.2 lbs, MB-EAT-A vs CTL) did not differ significantly between the two conditions (p=.87). In a sub-sample of 29 African American adolescents, 58% reported, a binge eating problem with most being mild to moderate in severity. Excessively eating on a regular basis and thinking about trying to control eating urges were the most common features present. Binge eating severity did not significantly correlate with anxiety, depression, or self-esteem. CONCLUSION: The MB-EAT-A program increased moderate and intense aerobic exercise and improved dietary habits in favor of low calorie and low fat foods in an overweight/obese adolescent sample. The MB-EAT-A program increased moderate and intense aerobic exercise and improved consumption of low calorie and low fat foods in overweight/obese adolescents. The study demonstrated feasibility of conducting the MB-EAT-A program in a high school setting, and good acceptability by the students. The successful implementation of MB-EAT-A points to the potential of school-based mindful eating programs as a means of addressing early onset of obesity in high-risk youth.

RESUMO

OBJECTIVE: To determine whether adding mindfulness-based eating and stress management practices to a diet-exercise program improves weight loss and metabolic syndrome components. METHODS: In this study 194 adults with obesity were randomized to a 5.5-month program with or without mindfulness training and identical diet-exercise guidelines. Intention-to-treat analyses with multiple imputation were used for missing data. The primary outcome was 18-month weight change. RESULTS: Estimated effects comparing the mindfulness to control arm favored the mindfulness arm in (a) weight loss at 12 months, -1.9 kg (95% CI: -4.5, 0.8; P = 0.17), and 18 months, -1.7 kg (95% CI: -4.7, 1.2; P = 0.24), though not statistically significant; (b) changes in fasting glucose at 12 months, -3.1 mg/dl (95% CI: -6.3, 0.1; P = 0.06), and 18 months, -4.1 mg/dl (95% CI: -7.3, -0.9; P = 0.01); and (c) changes in triglyceride/HDL ratio at 12 months, -0.57 (95% CI: -0.95, -0.18; P = 0.004), and 18 months, -0.36 (95% CI: -0.74, 0.03; P = 0.07). Estimates for other metabolic risk factors were not statistically significant, including waist circumference, blood pressure, and C-reactive protein. CONCLUSIONS: Mindfulness enhancements to a diet-exercise program did not show substantial weight loss benefit but may promote long-term improvement in some aspects of metabolic health in obesity that requires further study.

RESUMO

PURPOSE: To determine whether fluoxetine improves overall quality of life (QOL) in advanced cancer patients with symptoms of depression revealed by a simple survey. PATIENTS AND METHODS: One hundred sixty-three patients with an advanced solid tumor and expected survival between 3 and 24 months were randomly assigned in a double-blinded fashion to receive either fluoxetine (20 mg daily) or placebo for 12 weeks. Patients were screened for at least minimal depressive symptoms and assessed every 3 to 6 weeks for QOL and depression. Patients with recent exposure to antidepressants were excluded. RESULTS: The groups were comparable at baseline in terms of age, sex, disease distribution, performance status, and level of depressive symptoms. One hundred twenty-nine patients (79%) completed at least one follow-up assessment. Analysis using generalized estimating equation modeling revealed that patients treated with fluoxetine exhibited a significant improvement in QOL as shown by the Functional Assessment of Cancer Therapy-General, compared with patients given placebo (P =.01). Specifically, the level of depressive symptoms expressed was lower in patients treated with fluoxetine (P =.0005), and the subgroup of patients showing higher levels of depressive symptoms on the two-question screening survey were the most likely to benefit from treatment. CONCLUSION: In this mix of patients with advanced cancer who had symptoms of depression as determined by a two-question bedside survey, use of fluoxetine was well tolerated, overall QOL was improved, and depressive symptoms were reduced.

RESUMO

PURPOSE: To evaluate the association between quality-of-life (QOL) impairment as reported by patients and QOL impairment as judged by nurses or physicians, with and without consideration of spiritual well-being (SWB). PATIENTS AND METHODS: A total of 163 patients with advanced cancer were enrolled onto a therapeutic trial, and cross-sectional data were derived from clinical and demographic questionnaires obtained at baseline, including assessment of patient QOL and SWB. Clinicians rated the QOL impairment of their patients as mild, moderate, or severe. Clinician-estimated QOL impairment and patient-derived QOL categories were compared. Correlation coefficients were estimated to associate QOL scores using different instruments. The analysis of variance method was used to compare Functional Assessment of Cancer Therapy-General scores on categorical variables. RESULTS: There was no significant association between self-assessment scores and marital status, education level, performance status, or predicted life expectancy. However, a strong relationship between SWB and QOL was noted (P <.0001). Clinician-estimated QOL impairment matched the level of patient-derived QOL correctly in approximately 60% of cases, with only slight variation depending on the method of categorizing patient-derived QOL scores. The accuracy of clinician estimates was not associated with the level of SWB. Interestingly, a subset analysis of the inaccurate estimates revealed an association between lower SWB and clinician underestimation of QOL impairment (P =.0025). CONCLUSION: Clinician estimates of QOL impairment were accurate in more than 60% of patients. SWB is strongly associated with QOL, but it is not associated with the overall accuracy of clinicians' judgments about QOL impairment.
