RESUMEN

Elucidating psychological characteristics associated with emotional eating may further inform interventions for this behaviour related to eating psychopathology. The present systematic review aimed to examine the relationship between alexithymia and self-reported emotional eating in adults, and provide a narrative synthesis of the existing literature. Using the PRISMA method for systematic reviews, six databases (MEDLINE, PsycInfo, PsycArticles, PubMed, SCOPUS, and Web of Science) were searched for peer-reviewed, quantitative research published between January 1994 and 20th July 2021, when the searches were conducted. Eligible articles investigated the association between alexithymia, as measured by the Toronto Alexithymia Scale (Bagby, Parker, & Taylor, 1994), and emotional eating, as measured by any validated self-report instrument. Nine cross-sectional articles were reviewed, and risk of bias was assessed using the Appraisal Tool for Cross-Sectional Studies (Downes, Brennan, Williams, & Dean, 2016). A narrative synthesis of articles suggests positive associations between alexithymia and self-reported emotional eating. Five measures of emotional eating were used across articles, with limited but consistent evidence for the relationship between alexithymia and emotional eating as measured by the Dutch Eating Behaviour Questionnaire (Van strien et al., 1986). Further research is required to add evidence to the nature of the relationship between alexithymia and emotional eating, and to explore mechanisms that might underpin any relationships. Understanding the association between alexithymia and emotional eating may support strategies and interventions for those seeking help for emotional eating and related eating behaviours.

RESUMEN

BACKGROUND: Dietary restraint has been linked to deficits in the ability to recall detailed memories of personally experienced events (referred to as autobiographical memory specificity). As priming with healthy foods increases the salience of restraint it would be expected to lead to greater deficits in memory specificity. OBJECTIVE: To determine if priming word cues with images of healthy or unhealthy foods would influence the specificity of memory retrieval, and if deficits in memory specificity would be more evident in those reporting higher levels of dietary restraint, or currently dieting. METHODS: Sixty female undergraduates self-reported if they were currently dieting and completed measures of mood, restraint, and disinhibition, and a modified version of the autobiographical memory task. Participants were presented with positive and negative words (unrelated to eating concerns) and asked to retrieve a specific memory in response to each cue. A food image was shown prior to each word cue; half of the participants were primed with images of healthy foods and half with images of unhealthy foods. RESULTS: As expected, participants primed with healthy foods retrieved fewer specific memories than did those primed with unhealthy foods. However, neither restraint nor current dieting behaviour was associated with memory specificity. CONCLUSIONS: Differences in memory specificity between the priming conditions cannot be explained in terms of increased salience of restraint. However, it is plausible that unhealthy images led to an increase in positive affect, which in turn improved memory specificity. LEVEL OF EVIDENCE: Level I: Evidence obtained from: at least one properly designed experimental study.

RESUMEN

Emotions play an important role in overeating, yet there is little research looking at practical strategies to reduce overeating in response to a negative mood. In three different experimental studies, we tested if exposure to music can reduce food consumption in a negative mood. Female undergraduates (N = 120-121 in each study) completed a measure of emotional eating and reported baseline hunger. Mood ratings were taken at baseline, post-mood induction and post-eating. All participants were given a mood induction (sadness for study 1, stress for studies 2 and 3) and allocated to one of three music conditions (self-chosen in study 3) or a silent (control) condition. Music was selected from three pieces reported by each participant as being listened to regularly when experiencing the negative mood being examined (sadness or stress) in order to provide solace (comforting music), diversion (distracting positive music), or discharge (angry and/or sad music). Participants were provided with several snack foods to consume whilst completing a mock taste test and intake (in grams) was compared between conditions. In study 1 participants in the music for discharge condition consumed less than those in the control condition. Moreover, participants with high levels of self-reported EE ate more crisps in the control than in the distraction condition. In study 2 participants in the solace condition consumed less than those in the control and discharge conditions. In study 3 most participants chose music for diversion; this did not, however, lead to lower consumption, despite a reduction in reported stress. Overall, the results of these studies indicate that listening to certain types of music might reduce emotion-related eating after controlling for hunger using a standardized pre-session snack.

RESUMEN

Background: Mindful eating has been described as significant in motivating research and clinical outcomes in weight regulation and healthy eating. The use of psychometric tools to measure mindful eating is problematic, with results often leading to interpretations that are not reflective of mindful eating theory and fundamentals of mindfulness. Aim: In this research, we explored the Mindful Eating Behaviour Scale (MEBS) within a British sample to validate the factorial structure, and widen the use of a scale that appears appropriate for measuring mindful eating. Methods: A community sample (n = 742) was recruited via social media, and the findings supported the factorial structure proposed through the original Dutch sample. Predictive validity was also assessed, with the scale and subscales predicting fat and sugar consumption. Results: Cronbach's α values were acceptable and similar to the original findings, also supporting the internal consistency of the scale. Conclusion: While factorial structure, predictive validity and internal consistency propose a scale that can be adopted with English speaking populations, we propose the potential of furthering scientific inquiry on mindful eating research by highlighting the behavioural aspects of the scale.

RESUMEN

PURPOSE: Research has drawn associations between Mindful Eating (ME) and perfectionism in the aetiology and treatment of eating disorders (ED), but understanding into the relationship between these factors and Orthorexia nervosa (ON) is limited. The purpose of this research is to explore the relationship between perfectionism, ME, and ON. METHOD: Participants (n = 670) completed the Düsseldorf Orthorexia scale, the Mindful Eating Behavior scale, and the Big-Three Perfectionism scale Short-form, to reveal the relationship between ON, ME, and perfectionism. The relationship was assessed using correlational and regression analyses. RESULTS: A positive association was observed between perfectionism and ON. Moreover, perfectionism demonstrated a significant negative correlation with three out of four ME facets, with "eating without distraction" displaying the highest correlation. The "eating with awareness" facet of ME demonstrated a significant relationship with ON, in a negative direction. An unexpected relationship was observed between the focused eating facet of ME and ON, with a positive association being found. A further regression analysis revealed both perfectionism and ME to predict orthorexic tendencies. CONCLUSION: These findings identify a relationship between ON, ME, and perfectionism. It offers suggestion for the complexity of ME, and how it should be recognised by its different components, estimating a differential predictability and estimation of ON. Further research is required to clarify the direction of causality in the relationships observed, to inform the clinical diagnoses and intervention of ON. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

RESUMEN

Emotional eating, generally defined as (over)-eating in response to negative emotions, has been associated with poor physical and psychological outcomes. During a time of heightened negative affect, it is important to understand the impact of the COVID-19 pandemic and associated lockdown measures on eating behaviours, and further elucidate the ways in which emotional eating is related to emotion dysregulation and impaired abilities to identify emotions (i.e. alexithymia). The aims of this study were to explore perceived changes in eating behaviours in relation to self-reported negative affect during the pandemic and to examine direct and indirect effects of alexithymia on emotional eating. An online questionnaire measured these constructs in the general population of the United Kingdom (n = 136). Findings demonstrated that those who reported changes to their eating behaviours during the pandemic also reported greater levels of depression during the same time frame. Mediation analyses revealed that difficulties identifying and describing feelings both predicted emotional eating indirectly via emotion dysregulation. Findings contribute to the understanding of the mechanisms underpinning the relationship between alexithymia and emotional eating and describe changes to eating behaviours during COVID-19. We discuss how these findings should be applied, and recommendations for future research.

RESUMEN

PURPOSE: This study evaluated the effectiveness of a self-managed home-based moderate intensity walking intervention on psychosocial health outcomes among breast cancer patients undergoing chemotherapy. METHODS: The randomised controlled trial compared a self-managed, home-based walking intervention to usual care alone among breast cancer patients receiving chemotherapy. Outcome measures included changes in self-report measures of anxiety, depression, fatigue, self-esteem, mood and physical activity. Fifty participants were randomised to either the intervention group (n = 25), who received 12 weeks of moderate intensity walking, or the control group (n = 25) mid-way through chemotherapy. Participants in the intervention group were provided with a pedometer and were asked to set goals and keep weekly diaries outlining the duration, intensity and exertion of their walking. Levels of psychosocial functioning and physical activity were assessed pre- and post-intervention in both groups. RESULTS: The intervention had positive effects on fatigue (F = 5.77, p = 0.02), self-esteem (F = 8.93, p ≤ 0.001), mood (F = 4.73, p = 0.03) and levels of physical activity (x (2) = 17.15, p = 0.0011) but not anxiety (F = 0.90, p = 0.35) and depression (F = 0.26, p = 0.60) as assessed using the HADS. We found an 80% adherence rate to completing the 12-week intervention and recording weekly logs. CONCLUSION: This self-managed, home-based intervention was beneficial for improving psychosocial well-being and levels of physical activity among breast cancer patients treated with chemotherapy. TRIAL REGISTRATION: Current Controlled Trials ISRCTN50709297.

RESUMEN

BACKGROUND: Evidence suggests chemotherapy treatment for breast cancer is associated with side effects such as cognitive impairment in domains of memory, attention, concentration and executive function. Cognitive impairments reported by patients have been associated with higher levels of emotional distress. To date, intervention studies to alleviate cognitive impairment associated with chemotherapy have focused on psycho-educational techniques or cognitive training. Studies have not yet considered physical activity as a potential for alleviating cognitive problems. Physical activity interventions are reported to be effective in alleviating emotional distress and fatigue in those with breast cancer. They have also been reported to improve cognitive functioning in the elderly, in those suffering with dementia and in children. We propose that physical activity could also help to alleviate cognitive impairments in women diagnosed with breast cancer. The study has been designed using a recently developed taxonomy of behaviour change techniques to reliably report the content of the intervention to allow future replication. METHOD: This study will deliver a home-based moderate intensity walking intervention to women diagnosed with breast cancer mid-way through their chemotherapy treatment and will compare them to patients receiving usual care alone. The primary outcome measure for this intervention is changes in an objective measure of memory assessed using the Digit Span. Secondary outcome measures include: objective measures of executive function; attention; visual spatial skills; self report cognitive function; self-report fatigue; anxiety; depression; mood and self-esteem. As emotional distress has been associated with self-reporting of cognitive problems, this intervention will further test whether emotional distress mediates between the amount of walking undertaken during the intervention period and levels of self-reported cognitive functioning. DISCUSSION: The development of an effective intervention for preventing difficulties in emotional and cognitive functioning of cancer patients' post-treatment will help to guide health care professionals to improve patients' overall quality of life. It will also provide direction for future research, ultimately to improve the day to day functioning of breast cancer survivors. TRIAL REGISTRATION: Current Controlled Trials ISRCTN50709297.

RESUMEN

This study aimed to examine the factor structure of the Mealtime Emotions Measure for adolescents (MEM-A), a novel measure of emotional responses experienced during family mealtimes. Additionally, it examined gender differences in mealtime emotions and also the relationships between mealtime emotions and levels of eating psychopathology, when controlling for anxiety or depression. Adolescent participants (N = 527; 282 girls, 245 boys) with a mean age of 15.9 years completed the new mealtime measure for adolescents (MEM-A), in addition to questions about family mealtime atmosphere, and measures assessing symptoms of anxiety, depression, and eating psychopathology. Factor analysis produced a three factor solution for the MEM-A with two subscales relating to different types of negative mealtime emotions (Anxiety-related mealtime emotions and Anger-related mealtime emotions) and one subscale relating to Positive mealtime emotions. Generally, girls reported experiencing more Anxiety-related mealtime emotions compared to boys. Having conducted separate analyses controlling for levels of either anxiety or depression, there were several significant associations for both girls and boys between mealtime emotions, particularly Anxiety-related emotions, and eating psychopathology. The findings suggest that some mealtime emotions are associated with increased eating psychopathology. Replication and detailed examination of these emotional responses is required.

RESUMEN

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.

RESUMEN

BACKGROUND: Working-aged individuals diagnosed and treated for cancer require support and assistance to make decisions regarding work. However, healthcare professionals do not consider the work-related needs of patients and employers do not understand the full impact cancer can have upon the employee and their work. We therefore developed a work-related guidance tool for those diagnosed with cancer that enables them to take the lead in stimulating discussion with a range of different healthcare professionals, employers, employment agencies and support services. The tool facilitates discussions through a set of questions individuals can utilise to find solutions and minimise the impact cancer diagnosis, prognosis and treatment may have on their employment, sick leave and return to work outcomes. The objective of the present article is to describe the systematic development and content of the tool using Intervention Mapping Protocol (IMP). METHODS: The study used the first five steps of the intervention mapping process to guide the development of the tool. A needs assessment identified the 'gaps' in information/advice received from healthcare professionals and other stakeholders. The intended outcomes and performance objectives for the tool were then identified followed by theory-based methods and an implementation plan. A draft of the tool was developed and subjected to a two-stage Delphi process with various stakeholders. The final tool was piloted with 38 individuals at various stages of the cancer journey. RESULTS: The tool was designed to be a self-led tool that can be used by any person with a cancer diagnosis and working for most types of employers. The pilot study indicated that the tool was relevant and much needed. CONCLUSIONS: Intervention Mapping is a valuable protocol for designing complex guidance tools. The process and design of this particular tool can lend itself to other situations both occupational and more health-care based.

RESUMEN

OBJECTIVE: This research had two aims. First, to assess the current mealtime practices within UK eating disorders units. Second, to investigate staff perspectives of these mealtimes, including their involvement and understanding of patients' experience. METHOD: Study 1 involved a survey to assess mealtime protocols across 22 eating disorders units. In Study 2, sixteen semistructured interviews were conducted with staff at three eating disorders units. RESULTS: Between and within-unit variation exist regarding the implementation of mealtimes. Thematic analysis revealed that staff perceived their provision of mealtimes to be influenced by their own interpersonal difficulties created by the meals. Additionally, they perceived that these issues could be aided by forward planning, successful teamwork, and focused staff training. DISCUSSION: There is a need for specialized mealtime implementation training. Furthermore, research is required to evaluate current mealtime practices from patient perspectives and to determine the impact of modified mealtime approaches on treatment outcome.

RESUMEN

Significant facial emotion recognition (FER) deficits have been observed in participants exhibiting high levels of eating psychopathology. The current study aimed to determine if the pattern of FER deficits is influenced by intensity of facial emotion and to establish if eating psychopathology is associated with a specific pattern of emotion recognition errors that is independent of other psychopathological or personality factors. Eighty females, 40 high and 40 low scorers on the Eating Disorders Inventory (EDI) were presented with a series of faces, each featuring one of five emotional expressions at one of four intensities, and were asked to identify the emotion portrayed. Results revealed that, in comparison to Low EDI scorers, high scorers correctly recognised significantly fewer expressions, particularly of fear and anger. There was also a trend for this deficit to be more evident for subtle displays of emotion (50% intensity). Deficits in anger recognition were related specifically to scores on the body dissatisfaction subscale of the EDI. Error analyses revealed that, in comparison to Low EDI scorers, high scorers made significantly more and fear-as-anger errors. Also, a tendency to label anger expressions as sadness was related to body dissatisfaction. Current findings confirm FER deficits in subclinical eating psychopathology and extend these findings to subtle expressions of emotion. Furthermore, this is the first study to establish that these deficits are related to a specific pattern of recognition errors. Impaired FER could disrupt normal social functioning and might represent a risk factor for the development of more severe psychopathology.

RESUMEN

Background: Alexithymia is an independent predictor of symptoms of eating disorders, but also influences disordered eating in clinical samples indirectly via negative affect (depression and anxiety). The aim of the current work was to establish if alexithymia predicts disordered eating in a non-clinical sample directly and indirectly (via negative affect). Methods: A sample of healthy females (n = 248) completed measures of depression, anxiety, alexithymia, and disordered eating (drive for thinness, bulimia, and body dissatisfaction). Bias-corrected bootstrapping was used to conduct parallel mediation analyses to determine if negative affect (depression and anxiety) mediated the influence of alexithymia on disordered eating. Results: The relationship between alexithymia (difficulty identifying feelings) and drive for thinness was mediated by depression but not anxiety. The link between difficulty identifying feelings and bulimia was mediated by anxiety but not depression. The correlation between alexithymia (difficulty describing feelings) and body dissatisfaction was mediated by both depression and anxiety. However, after controlling for negative affect, difficulty identifying feelings remained an independent predictor of drive for thinness, and difficulty describing feelings remained an independent predictor of body dissatisfaction. Conclusion: Facets of alexithymia (DIF and DDF) directly predict disordered eating in healthy participants as well as indirectly via depression and anxiety. These findings suggest that targeted interventions to improve the ability of individuals to identify and describe their feelings could be beneficial in reducing disordered eating, particularly in those "at risk" of developing eating disorders.

RESUMEN

The aim of this study was to determine the effects of distraction and focused attention on both food intake and accuracy of perceived intake in women with non-clinical levels of disordered eating. In a laboratory study, twenty-seven young women consumed three identical pasta meals once a week for three consecutive weeks. Meals were eaten ad libitum during a control and two test conditions, in which attention was either diverted away from (distraction condition) or directed towards food-related stimuli (focused attention condition). They also completed the drive for thinness, bulimia and body dissatisfaction subscales of the Eating Disorders Inventory-2. Intake was significantly higher in the distraction than in the control or focused attention conditions, but was not related to eating psychopathology. A measure of accuracy of perceived intake indicated that drive for thinness was associated with overestimation of food intake in the focused attention condition. This study suggests that distraction could promote food intake in all non-clinical consumers, irrespective of individual differences in eating behaviours. Furthermore, it suggests that those with a high drive for thinness may overestimate intake when required to focus on their food. These findings could have implications for mealtime interventions in the treatment of eating disorders.

RESUMEN

Emotion recognition deficits have consistently been reported in clinical and sub-clinical disordered eating. However, most studies have used static faces, despite the dynamic nature of everyday social interactions. The current aims were to confirm previous findings of emotion recognition deficits in non-clinical disordered eating and to determine if these deficits would be more evident in response to static as compared to dynamic emotional stimuli. We also aimed to establish if these emotion recognition deficits could be explained by comorbid psychopathology (depression, anxiety or alexithymia). Eighty-nine females were assigned to groups based on scores on the Eating Disorders Inventory (EDI); high (n = 45) and low (n = 44). Participants were presented with emotional faces and video clips portraying fear, anger, disgust, sadness, happiness, surprise and neutral affect. As predicted, the high EDI group correctly recognised fewer emotional displays than did the low EDI group. However, this deficit was not more evident for negative as opposed to positive emotions. Furthermore, the deficit was not larger for static stimuli in comparison to dynamic. Overall emotion recognition accuracy was negatively associated with Drive for Thinness, but not Bulimia or Body Dissatisfaction. Importantly, the emotion recognition deficits observed in the high EDI group and that were associated with eating disorder symptoms were independent of depression, anxiety and alexithymia. Findings confirm that even minor elevations in disordered eating are associated with poorer emotion recognition. This is important, as problems in recognition of the emotional displays of others are thought to be a risk factor for clinical eating disorders.

RESUMEN

BACKGROUND: Cancer related cognitive impairments have been subjectively reported and objectively detected in breast cancer patients treated with chemotherapy and are known to have a profound negative impact on productivity, psychosocial well-being and overall quality of life. Moderate levels of walking are known to be of benefit to the psychosocial well-being of those affected by breast cancer and for managing cognitive impairment in healthy adults, children, and the elderly. The purpose of this study is to investigate the effects of a home-based, self-managed, moderate intensity walking intervention on subjective and objective cognitive functioning in breast cancer patients undergoing chemotherapy. METHODS: A home-based, self-managed intervention that consisted of moderate levels of walking was compared to usual care among breast cancer patients treated with chemotherapy in a randomised controlled trial. Outcome measures included changes in subjective (CFQ) and objectively detected cognitive functioning (Stroop, SART and two subscales from the WAIS- Digit Span and Block Design). Fifty participants were randomised to either the intervention group (n = 25), who completed 12 weeks of moderate intensity walking, or to the control group (n = 25) mid-way through chemotherapy. RESULTS: Compared with the control group, the self-managed walking intervention had positive effects on perceived cognitive function but not on sustained attention, executive function, memory or visual spatial skills when assessed objectively using neuropsychological measures. CONCLUSION: This home-based, self-managed intervention is beneficial for protecting against perceived cognitive decline in breast cancer patients treated with chemotherapy. There is a need for further research to objectively assess cognitive decline within this population with larger sample sizes of patients. TRIAL REGISTRATION: Current Controlled Trials ISRCTN50709297.

RESUMEN

BACKGROUND: Young children can regulate energy precisely in the short term, showing the potential for an innate compensation mechanism of eating behavior. However, data suggest that precise compensation is attenuated as a function of increasing adiposity, parental feeding style, and age. Common variation in candidate obesity genes may account for some of the individual variation observed in short-term energy compensation. Polymorphisms in the peroxisome proliferator-activated receptor gamma (PPARG) and beta-adrenergic receptor (ADRB3) genes have been linked to increased body mass index (BMI; in kg/m(2)), obesity, and more recently dietary nutrients and preferences. In addition, common variation in ADRB3 interacts with PPARG to modulate adult body weight. OBJECTIVE: This study investigated whether variants in these genes were associated with measurable effects on child eating behavior. DESIGN: Children (n=84) aged 4-10 y were prospectively selected for variants of the PPARG locus (Pro12Ala, C1431T). Heights and weights were measured. Energy intake from a test meal was measured 90 min after ingestion of a no-energy (NE), low-energy (LE), or high-energy (HE) preload, and the compensation index (COMPX) was calculated. RESULTS: BMI differed significantly by gene model, whereby Pro12Ala was associated with a lower BMI. Poor COMPX was associated with the PPARG T1431 allele (P=0.009). There was a significant interaction between COMPX and the ADRB3 Trp64Arg variant in modulating compensation (P=0.003), whereas the Arg64 allele was associated with good compensation (P=0.001). CONCLUSIONS: This is the first study to suggest that a genetic interaction involving ADRB3 and PPARG variants influences eating behavior in children.

RESUMEN

This study aimed to: (i) determine if the attention bias towards angry faces reported in eating disorders generalises to a non-clinical sample varying in eating disorder-related symptoms; (ii) examine if the bias occurs during initial orientation or later strategic processing; and (iii) confirm previous findings of impaired facial emotion recognition in non-clinical disordered eating. Fifty-two females viewed a series of face-pairs (happy or angry paired with neutral) whilst their attentional deployment was continuously monitored using an eye-tracker. They subsequently identified the emotion portrayed in a separate series of faces. The highest (n=18) and lowest scorers (n=17) on the Eating Disorders Inventory (EDI) were compared on the attention and facial emotion recognition tasks. Those with relatively high scores exhibited impaired facial emotion recognition, confirming previous findings in similar non-clinical samples. They also displayed biased attention away from emotional faces during later strategic processing, which is consistent with previously observed impairments in clinical samples. These differences were related to drive-for-thinness. Although we found no evidence of a bias towards angry faces, it is plausible that the observed impairments in emotion recognition and avoidance of emotional faces could disrupt social functioning and act as a risk factor for the development of eating disorders.

RESUMEN

BACKGROUND: Young children accurately compensate for energy-dense preloads consumed before test meals. The accuracy of compensation seems to deteriorate as a function of age. OBJECTIVE: The hypothesis that accurate energy compensation varies by age, body mass index, and individual characteristics of children and their mothers was tested. DESIGN: Energy intake (EI) from a test meal was measured in 74 children aged 6-9 y 90 min after the ingestion of no-energy (NE), low-energy (LE), or high-energy (HE) preload snacks. The NE preload consisted of 250 mL water, the LE preload consisted of a 56-g muffin + a 250-mL orange drink (783 kJ), and the HE preload consisted of a 56-g muffin + a 250-mL orange drink (1628 kJ). RESULTS: A significant dose-related reduction in EI was found after the preloads; younger children adjusted more effectively than did older children, although total EI (including preload energy) indicated that the adjustment was not accurate. The compensation index (COMPX) differed by preload and age group; COMPX scores were higher between the NE and LE preloads (younger children: 44.4 +/- 9.3%; older children: 57.0 +/- 11.6%) than between the NE and HE preloads (39.6 +/- 4.9%; 31.3 +/- 6.2%) and the LE and HE preloads (35.2 +/- 7.8%; 7.4 +/- 9.8%). This finding indicates a more consistent response across preloads and a greater sensitivity to energy load by younger than by older children. High interindividual variation and low intraindividual variation in COMPX was found. The tendency to over- or undereat in response to the preloads (deviation from perfect) correlated directly and positively with maternal concerns about child overweight, not with actual BMI. CONCLUSIONS: The children adjusted their EIs in response to different preloads, and the younger children did so more effectively than did the older children. Poor short-term energy compensation may constitute a behavioral marker for positive energy balance.
