Mindfulness moderates the relationship between emotional eating and body mass index in a sample of people with cystic fibrosis

A systematic review of observational studies exploring the relationship between health and non-weight-centric eating behaviours

Eating behaviour that does not centralise weight, otherwise known as weight-neutral, is associated with improved physical and psychological health, and greater health promoting behaviours. However, consolidated evidence is lacking. This study aimed to systematically evaluate 'health-centric' eating behaviour reflective of weight-neutral approaches, and their relationship with health (physical and mental) and health promoting behaviours. A systematic search was performed, identifying observational studies with adult populations, ≥1 physical/mental health outcome(s), and ≥1 validated measure(s) of health-centric eating behaviour. Study design, sample characteristics and outcomes were extracted and characterised into four domains. Our search identified 8281 records, with 86 studies, 75 unique datasets, and 78 unique exposures including 94,710 individuals. Eating behaviours included intuitive eating (n = 48), mindful eating (n = 19), and eating competence (n = 11). There were 298 outcomes identified for body composition, size, and physical health (n = 116), mental health and wellbeing (n = 123), health promoting behaviours (n = 51) and other eating behaviour (n = 8). Higher levels of intuitive eating, mindful eating and eating competence were significantly related to a lower BMI, better diet quality and greater physical activity. Higher intuitive and mindful eating were significantly related to lower levels of disordered eating, and depressive symptoms, and greater body image, self-compassion, and mindfulness. Greater eating competence and intuitive eating were significantly related to higher fruit and vegetable intake, and greater eating competence to higher fibre intake and better sleep quality. Our results demonstrate that 'health-centric' eating behaviours are related to a range of favourable health outcomes and engagement in health promoting behaviours. These findings help to enhance our understanding of eating behaviours that do not centre around body weight, providing support for health-centric eating behaviour in healthcare. Future research should focus on intervention studies and more diverse population groups.

Dietary intake and quality among adults with cystic fibrosis: A systematic review

AIMS

This systematic review aims to describe the dietary quality, dietary intake and related behaviours of adults diagnosed with cystic fibrosis.

METHODS

A comprehensive literature search was conducted in four databases (Medline, CINAHL, EMBASE, CENTRAL); studies were included if they addressed dietary intake, diet quality or eating behaviours among adults (≥15 years) living with cystic fibrosis and were published from January 2000 to November 2022. The Mixed Methods Appraisal Tool was used to assess the risk of bias and quality of included studies. Findings were synthesised narratively.

RESULTS

Nineteen observational studies (n = 2236) were included and considered high to moderate quality. Most (13/19) studies reported that individuals with cystic fibrosis were consuming high-energy diets; where studies reported energy intake as a proportion of requirements met, energy intake was high, even when using individualised or cystic fibrosis-specific referents. In addition, fat intakes as a proportion of energy appeared high (29%-39% of total energy), particularly as current guidelines recommend macronutrient profile similar to the general population (<30% of total energy). There was considerable variation in the reporting of fatty acid profiles and other nutrients. Five studies reported on concerns regarding diet and eating in this population.

CONCLUSION

Findings from the current review suggest dietary intakes of adults with cystic fibrosis appear to be less than optimal and concerns about diet, weight and food may be emerging in this population. Future research utilising consistent measures of dietary assessment and reporting, reporting of medical therapies, and exploring potential concerns about diet and eating is warranted.

Evolution of nutritional management in children with cystic fibrosis - a narrative review

Nutrition has played a central role in the management and outcomes of people with cystic fibrosis (pwCF) since the 1970s. Advances in therapies and practices in recent decades have led to a significant change in the patient landscape with dramatic improvements in life expectancy, as well as quality of life, bringing with it new issues. Historically, cystic fibrosis was a condition associated with childhood and malnutrition; however, changes in patient demographics, nutritional assessment and fundamental nutritional management have evolved, and it has become an increasingly prevalent adult disease with new nutritional challenges, including obesity. This paper aims to describe these changes and the impact and challenges they bring for those working in this field. Nutritional professionals will need to evolve, adapt and remain agile to the wider range of situations and support required for a new generation of pwCF. Specialised nutrition support will continue to be required, and it will be additionally important to improve and optimise quality of life and long-term health.

Body appreciation and mindful eating in Lebanese adults: the mediating role of psychological distress

A gap in the literature exists about the associations between adaptive eating patterns like mindful eating, body appreciation and psychological distress within the Lebanese population. The current culture of acceptance and increased emphasis on wellbeing elicits interest in studying body acceptance and its correlates. The aim of the current study is to assess the mediating effect of psychological distress in the association between body appreciation and mindful eating behaviors among a sample of Lebanese adults. This cross-sectional study enrolled 465 participants. Men and women over the age of 18 were eligible to participate. Then, initial participants were asked to recruit other participants they know. Individuals who consented took an online questionnaire that contained the following scales: a section collecting sociodemographic information, Mindful Eating Behavior Scale, Depression Stress Anxiety Scale (DASS-8) and Body Appreciation (BAS-2). The results of the mediation analysis showed that psychological distress fully mediated the associations between body appreciation and eating with awareness/eating without distraction. Higher body appreciation was significantly associated with less psychological distress, whereas higher psychological distress was significantly associated with less eating with awareness/eating without distraction. However, body appreciation was not associated with eating with awareness/eating without distraction respectively. These findings could guide further research on different categories of adaptive eating patterns and positive body variables within the Lebanese population.

Does controlling for epicurean eating or the tendency to supersize food portions change the relationship between mindful eating and grazing?

The study examines the potential for Epicurean eating to offer fresh perspectives on the predictive value of mindful eating. This research seeks to ascertain whether accounting for Epicurean eating (or its antithesis, supersizing), could influence the previously identified negative relationship between mindful eating and grazing habits. In a cross-sectional study, 419 participants completed questionnaires on epicurean eating, grazing, and mindful eating. The findings suggested mindful eating and epicurean eating were significantly associated with grazing, with both variables accounting for a significant amount of variance in grazing. Further analysis of the mindful eating subscales showed that eating without distraction, eating with awareness, and hunger and satiety cues accounted for this association with grazing when epicurean eating was included. Finally, whilst eating without distraction, eating with awareness, and hunger and satiety cues were associated with grazing, preference for supersizing did not account for a significant amount of variance in the relationship with grazing. The complex interplay between grazing and mindful eating becomes more apparent when considering the influence of epicurean eating. Exploring cross-cultural factors through additional research could provide valuable insights into the dynamics of epicurean eating and grazing. Simultaneously, incorporating alternative mindful eating scales may yield a more nuanced interpretation of mindful eating. Collectively, these avenues of inquiry warrant further investigation. Limitations and future directions are discussed.

Mindful eating and eating behaviours in Greece: exploring the validity and reliability of two mindful eating scales and other eating behaviours for Greek-speaking populations

BACKGROUND

Mindful eating has seen an increase in clinical and non-clinical practices of changing health outcomes. Meanwhile, the restriction of not having validated scales in other languages proposes a barrier to exploring the impact of mindful eating cross-culturally, and specific to the present project, across Greek-speaking populations, limiting the potential of exploring the association with Mediterranean dieting.

METHODS

In the present research, volunteers (n = 706) completed online the Mindful Eating Behaviour Scale and the Mindful Eating Scale. A forward-backwards translation, leading to face validity, and was assessed for internal consistency (Cronbach's Alpha) and followed up by an assessment of the factorial structure of the scales. Divergent and convergent validity was explored using motivations to eat palatable foods, grazing, craving, Dusseldorf orthorexia, Salzburg emotional eating, and the Salzburg stress eating scales.

RESULTS

Results indicated that both scales displayed good internal consistency, and the assessment of the factorial structure of the scales was equally good and semi-consistent with the English versions, with parallel analyses and item loadings proposing problems that have been shown in critical review literature. Associations of mindful eating scales to other eating behaviours were replicated to previously established findings with English-speaking populations.

CONCLUSIONS

Findings that deviated from the expected outcomes are central to the discussion on the measurement of mindful eating, and further direction highlights the way forward for researchers and clinicians.

Translation and validation of the mindful eating behaviour scale in the Arabic language

BACKGROUND

There has been a drastic increase in the prevalence of obesity and its related diseases in the Arabic-speaking countries during the last decades along with a lack of public awareness about this awareness about this public health problem. This calls for the development of novel prevention and intervention strategies that are based on new approaches, including mindful eating. In this context, we aimed through this study to explore the factor structure, composite reliability, measurement invariance across sex, convergent and divergent validity of an Arabic translation of the Mindful Eating Behaviour Scale (MEBS).

METHODS

A cross-sectional study carried out between September and November 2022, and enrolled 359 participants, all aged above 18 years old and recruited from all Lebanon governorates. The questionnaire used included socio-demographic questions, and the following scales: The Mindful Eating Behavior Scale (MEBS), Rosenberg Self-Esteem Scale (RSES), Intuitive Eating Scale-2, and Depression Anxiety Stress Scale (DASS-8).

RESULTS

McDonald's ω values ranged from .82 to .95 or the four mindful eating domains, indicating the excellent internal consistency reliability of the scale. Our study also showed that fit indices from the confirmatory factor analysis confirmed the original four-factor structure model of the MEBS. Furthermore, our analyses suggested that configural, metric, and scalar invariance was supported across sex. Our results found no sex difference in all MEBS subscales scores. Finally, we found positive correlations between Focused eating, Hunger and satiety cues on one hand, and intuitive eating on the other hand. Moreover, greater Hunger and satiety cues scores were correlated with higher self-esteem and lower body mass index.

CONCLUSION

Our findings support the psychometric reliability and validity of the Arabic MEBS. We suggest, accordingly, that the scale will be of high clinical and research utility, and will help in the development of information-based interventions focused on mindful eating that are aimed to combat eating disorders and obesity in the Arab world.

The Mediating Role of Body Acceptance in Explaining the Relation of Mindfulness, Self-Compassion and Mindful Eating to Body Image in Gay Men and Bisexual Men

Objectives

Mindfulness and mindfulness-based constructs, such as self-compassion and mindful eating, have been positively associated with healthier eating and body related perceptions. Exploration of mindfulness and related concepts have not been investigated extensively in gay and bisexual men, a population where eating and body related concerns have been found to be widespread.

Method

Participants completed an online questionnaire, assessing mindfulness, self-compassion, mindful eating, body image and body acceptance. Correlation analysis and further mediation analysis was conducted to explore the relations between these constructs within the present sample (n = 163).

Results

A community sample showed a positive association of body image to mindfulness-based concepts, and negative to body non-acceptance, within the target population. Mediation analysis showed the role of body acceptance in explaining the relation between mindfulness, self-compassion and mindful eating to body image.

Conclusions

Findings highlight the importance of body acceptance when considering the development of a mindfulness or compassion-based intervention to attenuate body related issues among gay and bisexual men.

Exploring the role of mindful eating and self-compassion on eating behaviours and orthorexia in people following a vegan diet

Orthorexia nervosa (ON) is a new concept that is more prevalent in vegan populations. ON is characterised by obsessive focus on healthy eating, following restrictive dietary practices and dietary restrictions escalating over time. The aim of this study was to explore problematic eating behaviours in a vegan population, and to explore whether mindful eating and self-compassion have an impact on ON. Two hundred and eighty-seven females and twenty-eight males who followed a vegan diet completed scales in Orthorexia, Self-Compassion, Mindful, Emotional, External and Restraint Eating. The results indicated that individuals with high levels of ON display low levels of self-compassion, and high levels of restrained eating. Moreover, the findings indicated that self-compassion, but not mindful eating, partially mediated the relationship between restrained eating and orthorexia nervosa. The present results contribute to a better understanding of orthorexic eating behaviours in a vegan population, and identifies the mediating capacity of self-compassion. Further implications and future directions are discussed.Level of evidence: Level V, cross-sectional descriptive study.

Exploring Mindfulness and Mindful Eating and Visual Attention Towards Food Cues: Preliminary Findings

Continual exposure to energy dense foods is suggested to promote overeating and obesity. The aim of the present research was to explore whether or not mindfulness could reduce visual attention towards food cues. In two laboratory studies, participants with a normal weight range completed an eye-tracking paradigm, and their eye-movements were recorded. In study 1, participants were exposed to either mindfulness meditation or a control condition, and their eye-movements towards low energy density (LED) vs high energy density (HED) food cues were measured. In study 2, participants were assigned to a mindful eating condition using a Mindful Construal Diary (MCD) or a control condition, and their eye-movements towards LED or HED food vs. non-food cues were recorded. In study 1, participants in the mindfulness meditation condition had greater attention duration towards LED food cues, whilst those in the control condition exhibited greater attention duration towards HED food cues. In study 2, there were no significant differences in the maintenance of attentional biases towards food cues between the two conditions. Mindfulness meditation may be beneficial in increasing attention towards LED food cues. Future research should further explore the effect of mindfulness and mindful eating on visual attention towards food cues with people who suffer from excess weight or have obesity, and also within naturalistic settings.

Eating Disorders and Disordered Eating Behaviors in Cystic Fibrosis: A Neglected Issue

As with the majority of chronic diseases having specific nutrition recommendations, in cystic fibrosis (CF), the emphasis placed on patients regarding their diet and ideal body weight status often increases the risk of developing disordered eating behaviors and by inference, eating disorders (EDs). Body weight appears to be an important concern for patients with CF, with many patients struggling to lose weight. Between sexes, women appear more preoccupied with dieting compared to men, but exhibit a better body image, mainly due to their preference for a lower weight. Several comorbidities appear to change these dynamics, and visibly apparent factors, including scars, ports, and tubes, and the need for supplementary oxygen supply, may also influence body image perception. Disordered eating is usually initiated during a bout of pulmonary infection, with the patient feeling unwell to eat. Regarding the prevalence of EDs, research appears conflicting on whether it is higher among individuals with a CF diagnosis or not. As for comorbidities, anxiety and depression consist of the most common psychiatric diagnoses in CF, also greatly prevalent in EDs. Despite the plethora of studies, non-specific CF tools, small samples, and lack of data regarding important outcomes, including lung health, indicate the need for more research.

A Qualitative Exploration into Experiences and Attitudes Regarding Psychosocial Challenges, Self-compassion, and Mindfulness in a Population of Adults with Cystic Fibrosis

To investigate the current psychosocial challenges faced by adults with Cystic Fibrosis (CF), while exploring attitudes and experiences of mindfulness and self-compassion. Mindfulness and self-compassion are important resources for supporting psychological and physical well-being, yet there is limited research exploring these positive psychology concepts in CF literature. Twenty UK domiciled adults with a diagnosis of CF, took part in a semi-structured interview. Using a thematic analysis approach, four themes were developed: (a) "I didn't expect to be here": Surpassing the CF life expectancy, (b) "Am I psychologically bringing this upon myself?": Psychological complexities of CF, (c) "I've had to really learn to be kind to myself": The importance of compassion and being self-compassionate, (d) "I think it's a great tool": The benefits of practising mindfulness. This research demonstrates a robust need for increased integration of accessible psychological practices into routine CF-care and self-care for adults with CF. Particularly, practises and interventions that draw on the concepts of mindfulness and self-compassion, which may benefit patient's health and wellbeing profoundly.

The Challenges of Eating Well for People Living with Cystic Fibrosis: an Interview Study Exploring the Use of Mindful Eating Approaches and Behaviours to Support Optimal Nutritional Status

BACKGROUND

Nutritional status and weight are closely linked to lung function and health status in cystic fibrosis (CF). The investigation of eating behaviours has shown mindfulness practices to be useful in modifying eating behaviours, particularly with obesity; to date, no research specifically explores how these concepts may be utilised within a CF population who face specific challenges in eating behaviours.

METHOD

Adult patients (n = 20, M = 8, age range 21-62 years) were recruited from a UK CF regional centre to take part in qualitative semi-structured interviews. Experiences of eating behaviours focusing on the use of mindful (or mindless) eating as barriers and enablers to achieving and maintaining optimal nutritional status were explored. Data were analysed using thematic analysis with a contextualist approach to understand how participants experienced eating behaviours within the context of health and weight status.

RESULTS

Participants engaged readily in discussions of eating behaviour describing active self-regulation of food eaten and calorie intake. Participants who struggled to maintain weight employed strategies to increase calorie intake such as distraction and multitasking while eating. Most participants reported no pleasure in food, describing eating as another treatment to endure. Confusion existed around how to eat healthily for CF alongside co-morbid health conditions including diabetes, cholesterol and heart disease.

CONCLUSION

Participants were highly aware of their eating behaviours, engaging in intentional and deliberate preparations, which could be described as mindful, for making eating a more automatic or mindless activity. Modifications to usual mindful eating interventions are needed to support people with CF.

(Re)defining mindful eating into mindful eating behaviour to advance scientific enquiry

BACKGROUND

Mindful eating has exceeded two decades of scientific enquiry but defining mindful eating has proven to be quite challenging.

AIM

The inability to clearly define mindful eating led to variations in the description in academic and clinical literature, different psychometric tools and the development of a field that is lacking the preciseness that is needed to advance mindful eating - and the associated interventions - onto a level that is simple to comprehend and implement in practice.

METHODS

Drawing from traditional and contemporary mindfulness and mindful eating literature, this manuscript will attempt to define and describe mindful eating in the context of eating behaviours.

RESULTS

The review of the literature has resulted in challenging areas around the main principles that should be included in defining the term mindful eating, and highlights the distinction between mindfulness and mindful eating, as well as behaviour and decision making within the context of mindful eating.

CONCLUSION

In a field that is lacking transparency and methodological rigour, mindful eating behaviour is detailed as a new beginning in conducting precise experimental research and evidence-based interventions for clinical and non-clinical use.

Self-Compassion, Mindful Eating, Eating Attitudes and Wellbeing Among Emerging Adults

Mindful eating behavior and self-compassion have been individually shown to contribute to healthy eating. Evidence suggests that they may interact and that interaction may increase our understanding of eating behavior. The aim of the current study was to explore the relationship between mindful eating behavior, self-compassion, healthy/unhealthy weight, eating disorder and wellbeing in a sample of university students. An online survey using questionnaire data collection in a sample of 349 students (105 males and 244 females). Variables measured included body mass index (BMI), mindful eating behavior, eating attitudes, self-compassion and mental wellbeing. Regression and path analysis show mindful eating behavior and self-compassion to individually and interaction predict eating attitudes and wellbeing. BMI was shown to have a curvilinear relationship with mindful eating behavior, self-compassion and wellbeing with both the underweight and obese reporting lower self-compassion, less Mindful eating behavior, lower wellbeing and more likely to exhibit disordered eating. These results indicate that self-compassion and mindful eating behavior might be usefully targeted in interventions to prevent both obesity and eating disorder.

Exploring Associations Between Self-Compassion, Self-Criticism, Mental Health, and Quality of Life in Adults with Cystic Fibrosis: Informing Future Interventions

Self-compassion is increasingly recognised as an important and beneficial factor in quality of life and mental health-related research, but research within the adult cystic fibrosis (CF) population is scarce. In a cross-sectional study, 114 (56 female, 58 male) adults with CF completed and returned a series of validated questionnaires that assessed CF-related quality of life, negative emotional states (depression, anxiety and stress), self-compassion, and self-criticism. Quality of life and self-compassion were positively correlated, and each in turn were inversely correlated with negative emotional states and self-criticism. Negative emotional states correlated positively to self-criticism. Self-compassion and/or self-criticism moderated ten relationships between various sub-domains of quality of life and negative emotions. Psychological interventions that increase self-compassion may be beneficial for enhancing mental health and quality of life for adults with CF.

Understanding the relationship between negative emotional eating and binge eating: The moderating effects of acting with awareness and non-reactive mindfulness

OBJECTIVES

Negative emotional eating and binge eating are positively related, occur in diverse populations, and may be driven by similar mechanisms. Mindfulness facets such as acting with awareness, describe, non-judgement, non-reactive, and observe may moderate the relationship between these maladaptive eating phenotypes.

METHOD

A cross-sectional study assessed emotional eating-depression (Emotional Eating Scale-Revised, depression subscale), trait mindfulness facets (Five Facet Mindfulness Questionnaire-Short Form), and binge eating severity (Binge Eating Scale) in adults (N = 258).

RESULTS

Emotional eating-depression was less strongly associated with binge eating severity in participants with higher acting with awareness mindfulness. Emotional eating-depression was more strongly associated with binge eating severity in participants with higher non-reactive mindfulness.

CONCLUSIONS

Acting with awareness and non-reactive mindfulness may be important treatment targets in concurrent presentations of emotional eating-depression and binge eating.
