The neurohypophyseal hormone oxytocin and eating behaviors: a narrative review.

BACKGROUND: The neuropeptide oxytocin (OT) is crucial in several conditions, such as lactation, parturition, mother-infant interaction, and psychosocial function. Moreover, OT may be involved in the regulation of eating behaviors. METHODS: This review briefly summarizes data concerning the role of OT in eating behaviors. Appropriate keywords and medical subject headings were identified and searched for in PubMed/MEDLINE. References of original articles and reviews were screened, examined, and selected. RESULTS: Hypothalamic OT-secreting neurons project to different cerebral areas controlling eating behaviors, such as the amygdala, area postrema, nucleus of the solitary tract, and dorsal motor nucleus of the vagus nerve. Intracerebral/ventricular OT administration decreases food intake and body weight in wild and genetically obese rats. OT may alter food intake and the quality of meals, especially carbohydrates and sweets, in humans. DISCUSSION: OT may play a role in the pathophysiology of eating disorders with potential therapeutic perspectives. In obese patients and those with certain eating disorders, such as bulimia nervosa or binge/compulsive eating, OT may reduce appetite and caloric consumption. Conversely, OT administered to patients with anorexia nervosa may paradoxically stimulate appetite, possibly by lowering anxiety which usually complicates the management of these patients. Nevertheless, OT administration (e.g., intranasal route) is not always associated with clinical benefit, probably because intranasally administered OT fails to achieve therapeutic intracerebral levels of the hormone. CONCLUSION: OT administration could play a therapeutic role in managing eating disorders and disordered eating. However, specific studies are needed to clarify this issue with regard to dose-finding and route and administration time.

Body Image among Girls in Indonesia: Associations with Disordered Eating Behaviors, Life Engagement, Desire for Cosmetic Surgery and Psychosocial Influences.

Body image is an important risk factor for mental and physical health during adolescence. Nonetheless, few studies have empirically investigated body image among girls in Southeast Asia. This cross-sectional study examined the prevalence of body esteem (a holistic measure of body image assessing the degree of satisfaction with one's appearance, weight, and shape), associated behavioral outcomes, and potential psychosocial influences on body image among Indonesian girls to inform future intervention efforts. Girls across Indonesia with internet access (N = 318, Mage = 13.59 years) completed a questionnaire that assessed body image, disordered eating behaviors, appearance-related life engagement, desire for cosmetic surgery, appearance ideal internalization, media literacy, appearance-related teasing, and self-esteem. The younger girls' (10-13 years) responses were analyzed separately from those of the older girls (14-17 years). Over half of the girls did not have high body esteem. Approximately a quarter of the girls across both age groups reported restricting their food intake, emotionally eating, and/or engaging in excessive exercise, and over half desired cosmetic surgery. Disordered eating behaviors and a desire for cosmetic surgery were negatively correlated with body esteem. Hierarchical regression analyses found BMI, internalization, appearance-related teasing, and self-esteem were uniquely associated with body esteem among younger girls. Appearance-related teasing and self-esteem were positively associated with body esteem among older girls. These findings suggest body image interventions may be important for this population, with appearance-related teasing and self-esteem potentially useful targets for intervention efforts. Further prospective research to investigate these findings would be beneficial for a deeper understanding of body image risk factors for girls across Indonesia.

Eating Disorders and Dietary Supplements: A Review of the Science.

Disordered eating is a serious health concern globally. The etiology is complex and multidimensional and differs somewhat for each specific eating disorder. Several risk factors have been identified which include psychological, genetic, biochemical, environmental, and sociocultural factors. Poor body image, low self-esteem, teasing, family dynamics, and exposure to media images have also been identified as risk factors. While it is enticing to consider a single behavioral risk factor, doing so fails to consider the documented environmental, social, psychological, biological, and cultural factors that contribute to the development of an eating disorder in a multidimensional and complex integration that is undoubtedly unique to everyone. Focusing only on any one factor without taking the complex etiology into account is remiss. For example, it has been suggested that the use of dietary supplements may lead to eating disorders, despite a lack of evidence to support this conjecture. Therefore, the purpose of this review is to examine the evidence-based risk factors for eating disorders and discuss why connecting dietary supplements to eating disorder etiology is not supported by the scientific literature and may interfere with treatment. Established, effective prevention and treatment approaches for eating disorders should be the focus of public health initiatives in this domain.

Mindfulness facets differentially relate to self-reported negative and positive emotional eating types in treatment-seeking adults with overweight/obesity.

BACKGROUND: Mindfulness is a meaningful therapeutic target in the treatment of emotional eating in adults with overweight/obesity. Descriptive research mapping relations between mindfulness facets and emotional eating types in treatment-seeking adults with overweight/obesity is needed. METHODS: Cross-sectional relations between mindfulness facets (i.e., acting with awareness, describe, non-judgment, non-reactive, and observe; Five Facet Mindfulness Questionnaire-Short Form) and emotional eating types (i.e., self-reported negative and positive emotional eating; Emotional Eating Scale-Revised, Emotional Appetite Questionnaire) were examined in a treatment-seeking sample of adults with overweight/obesity (N = 63). RESULTS: Significant bivariate correlations revealed negative relations between mindfulness facets and emotional eating types. Multiple regressions revealed that higher describe (ß = - 0.42, p = 0.004) mindfulness was associated with lower self-reported emotional eating-anger/anxiety; higher non-reactive (ß = - 0.31, p = 0.01) and non-judgment (ß = - 0.28, p = 0.02) mindfulness were associated with lower self-reported emotional eating-depression; and higher non-judgment (ß = 0.26, p = 0.04) mindfulness was associated with higher self-reported emotional eating-positive. CONCLUSIONS: Describe, non-judgment, and non-reactive mindfulness were uniquely and significantly associated with eating in response to negative and positive emotions. Results suggest the potential need for intervention programs to be sensitive to the multidimensional nature of mindfulness in the treatment of distinct types of emotional eating in adults with overweight/obesity. LEVEL OF EVIDENCE: V, cross-sectional descriptive study.

Beyond Binge Eating: The Impact of Implicit Biases in Healthcare on Youth with Disordered Eating and Obesity.

(1) Background: Obesity and eating disorders (ED) can coexist resulting in worse health outcomes. Youth with ED are more likely to have obesity relative to peers with a healthy weight. Pediatric providers deliver first-line care to children and youth of all sizes and body shapes from infancy to adolescents. As healthcare providers (HCPs), we bring biases into our practice. Learning to recognize and address these biases is needed to provide the best care for youth with obesity. (2) Purpose: This paper aims to summarize the literature regarding the prevalence of ED beyond binge eating in youth with obesity and discuss how the intersection of weight, gender, and racial biases impact the assessment, diagnosis, and treatment of ED. We provide recommendations for practice and considerations for research and policy. (3) Conclusions: The assessment and treatment of ED and disordered eating behaviors (DEBs) in youth with obesity is complex and requires a holistic approach. This approach begins with identifying and understanding how one's implicit biases impact care. Providing care from a patient-centers lens, which considers how the intersection of multiple stigmatized identities increases the risk for DEBs in youth with obesity may improve long-term health outcomes.

Effectors of Pregorexia and Emesis among Pregnant Women: A Pilot Study.

During pregnancy, women tend to improve their lifestyle habits and refine their dietary intake. Quite often, however, these dietary improvements take an unhealthy turn, with orthorexia nervosa (ON) practices being apparent. The aim of the present pilot cross-sectional study was to assess the prevalence of ON tendencies and the incidence of pica and record diet practices in a sample of pregnant women. A total of 157 pregnant women were recruited through private practice gynecologists during the first months of 2021. Nutrition-related practices were recorded, orthorexic tendencies were assessed using the translated and culturally adapted Greek version of the ORTO-15 questionnaire, pica practices were evaluated with a binary question and nausea and emesis during pregnancy (NVP) was evaluated using the translated modified Pregnancy-Unique Quantification of Emesis and Nausea (mPUQE). Only two women reported pica tendencies, with ice and snow being the consumed items. The majority (61.1%) of women reported improving their diet since conception was achieved. Folic acid and iron oral nutrient supplements (ONS) were reportedly consumed by the majority of participants (87.9% and 72.6%, respectively) and 9.6% reported using herbal medicine products. The ORTO-15 score was reduced with tertiary education attainment, ART conception, being in the third trimester of pregnancy, consumption of folic acid and MV supplements and was only increased among women who were at their first pregnancy. The majority of participants experienced severe NVP and the remaining experienced moderate NVP. NVP was associated with lower hemoglobin levels, lack of supplementary iron intake, avoidance of gluten-containing foods, as well as with increased gestational weight gain. The results highlight the need to screen pregnant women for disturbed eating behaviors and nutrition-related problems, in order to ensure a healthy pregnancy outcome.

Eating and body image characteristics of those who aspire to the slim-thick, thin, or fit ideal and their impact on state body image.

The slim-thick ideal is characterized by a small waist and flat stomach, but large hips, thighs, and butt. Little research to date has examined the impact of this body-ideal on women's body image. The purpose of the current study was to investigate: 1) the impact of slim-thick, thin-, and fit-ideal imagery on women's body image, 2) the body ideals women most aspire to, and 3) eating and body image characteristics of women who aspire to each ideal. Participants were 123 female undergraduate students. Results revealed that experimental exposure to slim-thick- and fit-ideal imagery resulted in lower body satisfaction. Participants reported aspiring more to the fit and slim-thick-ideal than to the thin-ideal, and rated the slim-thick-ideal as the most attractive and desirable. Women who aspired to the thin- or slim-thick-ideal reported the greatest overall disordered eating. Women who aspired to the slim-thick-ideal reported greater dietary restraint, eating, shape and weight concerns, appearance ideal internalization, body image investment, and physical appearance perfectionism than those who aspired to the fit-ideal. Findings show that beauty ideals are shifting away from the thin-ideal toward a slim-thick-ideal. Slim-thick internalization may be harmful to women's well-being and should be addressed in body image and eating disorders interventions.

"Eat clean, train mean, get lean": Body image and health behaviours of women who engage with fitspiration and clean eating imagery on Instagram.

The present study examined the relationship between posting or viewing fitspiration and clean eating imagery in relation to body image, disordered eating, and compulsive exercise among women. Participants (269 women aged 18-30 years) who posted and/or viewed fitspiration, clean eating or travel imagery on Instagram completed an online cross-sectional questionnaire. Results showed engaging with fitspiration and clean eating material (either posting or viewing) was significantly positively associated with increased levels of compulsive exercise and athletic-ideal internalization. However, only viewing (not posting) fitspiration and clean eating content was significantly related to thin-ideal internalization and disordered eating symptomatology. Athletic-ideal internalization mediated the relationships between posting fitspiration/clean eating and disordered eating symptomatology and compulsive exercise. Both thin-ideal internalization and athletic-ideal internalization mediated the relationship between viewing fitspiration/clean eating material and disordered eating and compulsive exercise. Overall, the findings suggest that viewing fitspiration and clean eating content on Instagram is negatively associated with thin-ideal internalization and disordered eating symptomatology, however the same relationships do not exist for people who frequently post these types of material. The mediational pathways provide a nuanced understanding of how engaging with fitspiration and clean eating material on social media influences female users' body image and health behaviour.

Drunkorexia and trait mindfulness among college students.

Objective: Combined alcohol and disordered eating (drunkorexia) are alcohol fueled weight management behaviors. Mindfulness negatively relates to both disordered eating and alcohol use. Participants: Participants (n = 344, average age 20) were primarily female (85.2%, n = 293), and Caucasian (82.6%, n = 284). Methods: Students reported drunkorexia and mindfulness. Results: Drunkorexia behaviors were negatively correlated with Acting with Awareness (AA; full attention to a present moment; r = -.21, p < .001) and Nonjudgment (NJ; understanding and leniency toward oneself; r = -.22, p < .001). Drunkorexia motivations are significantly correlated with AA (r = -.13, p = .01) and NJ (r = -.18, p = .001). Structural equation modeling revealed higher levels of NJ related to higher levels of drunkorexia. Conclusion: The objective was to determine a potential relationship between drunkorexia behaviors and motivations, and trait mindfulness. Findings suggest a nonjudgmental disposition relates to lower levels of drunkorexia.

Effects of a mindfulness-induction on subjective and physiological stress response in adolescents at-risk for adult obesity.

BACKGROUND: Mindfulness-training may benefit stress response and stress-eating, yet few studies have experimentally tested these effects in adolescents. In this short communication, we report whether a brief mindfulness-induction affected acute stress response and stress-eating in adolescents at-risk for adult obesity. We explored disordered eating as a moderator. METHOD: Twenty-nine adolescents (age 14 ± 2 y) at-risk for adult obesity participated in a within-subjects, randomized crossover experiment. Following a 10-minute mindfulness or neutral-induction on different days in random order, the Trier Social Stress Test adapted for adolescents was administered, followed by an ad libitum lunch meal. Physiological stress response (heart rate, blood pressure) and subjective stress response (anxiety, mindlessness) were determined with area under the curve with respect to increase. Stress-eating was measured as test meal energy consumed. Global disordered-eating and binge-eating were assessed with the Eating Disorders Examination-Questionnaire. RESULTS: Relative to a neutral-induction, a mindfulness-induction reduced state anxiety response (p = .04). There were significant interactions of induction-type by global disordered-eating (p = .02) and binge-eating (p = .03), such that the mindfulness-induction most reduced anxiety response in adolescents with relatively lower global disordered-eating and those with no binge-eating. Induction-type also interacted with binge-eating in predicting diastolic blood pressure (p = .03). A mindfulness-induction, versus neutral-induction, most reduced diastolic blood pressure response in adolescents with binge-eating. CONCLUSIONS: Brief mindfulness-training may alter some aspects of acute stress response, with variations by disordered-eating. Future research should test alternative mindfulness induction-types (e.g., acceptance/self-compassion) to improve our understanding of how mindfulness-training may benefit adolescents at-risk for adult obesity.

Prevalence of Female Athlete Triad Risk Factors and Iron Supplementation Among High School Distance Runners: Results From a Triad Risk Screening Tool.

BACKGROUND: Investigations of the female athlete triad (Triad) in high school athletes have found that 36% had low energy availability, 54% had menstrual abnormalities, and 16% had low bone mineral density (BMD). Limited data are available showing the prevalence of these risk factors in high school distance runners or regarding best practice on screening for the Triad in the adolescent population. PURPOSE: To (1) evaluate the prevalence of Triad risk factors and iron supplementation in high school distance runners and (2) pilot a screening tool for Triad risk score. STUDY DESIGN: Descriptive epidemiology study. METHODS: The study population included female high school athletes who participated in cross-country/track. Participants completed a survey including questions regarding dietary habits, menstrual history, and bone stress injury (BSI) history. They then underwent evaluation of 25-hydroxyvitamin D, free triiodothyronine (T3), and dual-energy x-ray absorptiometry scan to measure body fat and BMD through use of age-, sex-, and ethnicity-matched Z scores. Triad scores were calculated. Relationships were analyzed using Spearman correlation coefficient. RESULTS: There were 38 study participants (mean age, 16.9 years). Average body mass index was 19.8 kg/m2. Disordered eating or eating disorders were reported in 76.3% of runners; in addition, 23.7% reported delayed menarche, 45.9% had a history of amenorrhea or oligomenorrhea, 42.1% had low BMD (Z score < -1.0), and 15.8% reported prior BSI. Low free T3 was significantly associated with higher Triad risk scores (r S = -0.36; P = .028). More than 42% of athletes were supplementing iron. CONCLUSION: The prevalence of Triad risk factors in high school distance runners was high. Free T3 was inversely associated with Triad score, which may serve as an indicator of low energy availability. Nearly half of the athletes were using iron supplementation.

Online imagery rescripting among young women at risk of developing an eating disorder: A randomized controlled trial.

OBJECTIVE: This study compared the effectiveness of two approaches to imagery rescripting (body versus general) among young women with an elevated risk of developing an eating disorder. METHOD: University students (N = 130 females) were randomly assigned to one of the four conditions: body or general imagery rescripting, psychoeducation, control. After initial brief laboratory training delivered online, participants in the imagery rescripting conditions were asked to practice imagery rescripting for 5 min each day for a week. Primary (global eating psychopathology, eating disorder behaviors, and body image acceptance) and secondary outcomes (self-compassion, fear of self-compassion, and dysfunctional attitudes) were measured at baseline and one-week follow up. RESULTS: Completer analyses showed both imagery rescripting conditions and psychoeducation had significant impact on global eating psychopathology and body acceptance (d = 0.60-0.78). Psychoeducation did not impact secondary variables, whereas body imagery rescripting improved self-compassion and fear of self-compassion (d = 0.61-0.80) and general imagery rescripting improved dysfunctional attitudes (d = 0.82) compared to control. Intent to treat analyses had similar but slightly less robust results. DISCUSSION: While three active groups had significant impact on the primary variables, imagery rescripting approaches had impact on other variables that maintain disordered eating. Future research should investigate the impact of combining psychoeducation and imagery rescripting in terms of impact on disordered eating.

Women's Experiences with a Mindful Eating Program for Binge and Emotional Eating: A Qualitative Investigation into the Process of Change.

Objectives: Mindfulness-based interventions (MBIs) have been shown to reduce engagement in disordered eating behaviors, although how these interventions engender change remains unclear. The objective of this exploratory qualitative study was to describe the experiences and perceived attitudinal and behavioral changes of women participating in a mindful eating program. Design: Focus group discussions were held with women participating in a community-based mindful eating program for binge and emotional eating. A semistructured interview guide was used to explore participants' conceptualizations of mindfulness-based attitudinal and behavior change, as related to food, eating, and body image. The focus group discussions were audio-recorded, transcribed, and analyzed using thematic analysis to identify salient concepts. Settings/Location: Focus group discussions were held at the Center for Mindfulness at the University of Massachusetts Medical School (UMMS) (United States). Participants: A sample of nine women who were enrolled in the mindful eating program at UMMS for problems with self-reported binge and/or emotional eating participated in this study. Results: Four themes were constructed that described a process of mindfulness-based behavior change, including (1) Learning Through Self-Awareness, (2) Self-Empowerment, (3) Mindful Choice-Making, and (4) Resilient Self-Care. An overarching description of the participants' perceived attitudinal and behavior changes was developed: "unforced freedom of choice, emerging from embodied awareness." Conclusions: These findings suggest that MBIs reduce may disordered eating behaviors through empowering women to make positive choices about food, eating, and coping, without focusing on weight control. Future research is needed to examine whether these findings replicate in larger and more diverse samples, and how they can be used to optimize and implement eating-specific MBIs in community-based settings.

Effects of Mindfulness-Based Intervention on the Treatment of Problematic Eating Behaviors: A Systematic Review.

Objectives: Emerging research interest focused on mindfulness-based interventions (MBIs) as a complementary approach for the treatment of problematic eating behaviors. This systematic review aims to comprehensively evaluate current evidence from randomized-controlled trials (RCTs) that have used the MBIs as the treatment for problematic eating concerns. Methods: Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses method for systematic reviews, electronic databases, including Ovid MEDLINE, Ovid Embase, AMED, Web of Knowledge, PsycINFO, Scopus, and The Cochrane Library, were systematically searched to identify up to June 2017. Hand search of the reference lists of related systematic reviews was also conducted for detecting additional studies. Eligible studies were RCTs that employed MBIs as the primary intervention for people with problematic eating or body image concerns. Results: A total of nine RCTs were included in this systematic review. In the majority of included studies, participants in MBI groups showed significant reduction in emotional eating, external eating, binge eating, and weight and shape concern. Findings also suggest that increasing mindful awareness of internal experiences and automatic patterns could be effective for the improvement of self-acceptance and emotional regulation, thereby reducing the problematic eating behaviors. Conclusion: This systematic review advances the understanding of MBIs as an complementary approach for problematic eating behavior treatment. Despite the variable trial qualities and some small sample sizes, this study provides initial evidence supporting the efficacy of the application of MBIs to a range of problematic eating concerns. The application of MBIs remains a promising approach for the treatment of problematic eating and merits further investigations.

Cardiac arrest and pulmonary hypertension in scurvy: a case report.

We report a case of a six-year-old boy who presented after a cardiac arrest, likely due to a pulmonary hypertensive crisis in the setting of vitamin C deficiency. After initially presenting with subacute multifocal bone lesions of unknown etiology, he experienced a pulseless electrical activity cardiac arrest while undergoing a diagnostic procedure under sedation. During his post-arrest convalescence, he developed persistent tachycardia and peripheral edema. An echocardiogram revealed findings consistent with significant pulmonary arterial hypertension, which was found to be responsive to inhaled nitric oxide. Laboratory investigation revealed undetectable levels of vitamin C, resulting in disclosure of a history of severe restrictive eating behavior. With ascorbate supplementation, the patient's pulmonary vasodilators were weaned and discontinued. Given his complete recovery, we suspect that the cardiac arrest and pulmonary hypertension were the consequence of a rare, but reversible, complication of scurvy.

Can Mindfulness Address Maladaptive Eating Behaviors? Why Traditional Diet Plans Fail and How New Mechanistic Insights May Lead to Novel Interventions.

Emotional and other maladaptive eating behaviors develop in response to a diversity of triggers, from psychological stress to the endless external cues in our modern food environment. While the standard approach to food- and weight-related concerns has been weight-loss through dietary restriction, these interventions have produced little long-term benefit, and may be counterproductive. A growing understanding of the behavioral and neurobiological mechanisms that underpin habit formation may explain why this approach has largely failed, and pave the way for a new generation of non-pharmacologic interventions. Here, we first review how modern food environments interact with human biology to promote reward-related eating through associative learning, i.e., operant conditioning. We also review how operant conditioning (positive and negative reinforcement) cultivates habit-based reward-related eating, and how current diet paradigms may not directly target such eating. Further, we describe how mindfulness training that targets reward-based learning may constitute an appropriate intervention to rewire the learning process around eating. We conclude with examples that illustrate how teaching patients to tap into and act on intrinsic (e.g., enjoying healthy eating, not overeating, and self-compassion) rather than extrinsic reward mechanisms (e.g., weighing oneself), is a promising new direction in improving individuals' relationship with food.

Imagery rescripting and cognitive dissonance: A randomized controlled trial of two brief online interventions for women at risk of developing an eating disorder.

OBJECTIVE: This pilot study compared two brief online interventions, imagery rescripting and cognitive dissonance, to an assessment-only control condition in a sample of body-dissatisfied young women at risk of developing an eating disorder. We examined the degree to which each intervention reduced disordered eating and modified risk and protective factors for eating disorders. METHOD: Female university students (N = 107, 17-28 years of age) completed a screening questionnaire, followed by random allocation to one of the three conditions, followed by a baseline assessment, body dissatisfaction induction, and brief online intervention. Participants in the active conditions then completed online daily home practice and a postintervention questionnaire. RESULTS: Findings provide qualified support for the imagery rescripting intervention, with participants reporting higher body image acceptance (Cohen's d = 0.49) than the cognitive dissonance condition, and higher self-compassion (d = 0.59) and lower levels of disordered eating (d = 0.59) than the control condition, at postintervention. There was no significant impact of cognitive dissonance on any factors. Change in body image acceptance and self-compassion mediated the relationship between allocated condition and change in disordered eating at postintervention. DISCUSSION: These findings provide preliminary support for the use of online-adapted imagery-based techniques (e.g., imagery rescripting) to reduce risk for the development of an eating disorder by strengthening protective factors (i.e., body image acceptance and self-compassion) and reducing disordered eating. Further exploration of the use of imagery strategies in the prevention of disordered eating is required, including prospective tests of the mechanisms of action.

Food Versus Pharmacy: Assessment of Nutritional and Pharmacological Strategies to Improve Bone Health in Energy-Deficient Exercising Women.

PURPOSE OF REVIEW: The review aims to summarize our current knowledge surrounding treatment strategies aimed at recovery of bone mass in energy-deficient women suffering from the Female Athlete Triad. RECENT FINDINGS: The independent and interactive contributions of energy status versus estrogen status on bone density, geometry, and strength have recently been reported, highlighting the importance of addressing both energy and estrogen in treatment strategies for bone health. This is supported by reports that have identified energy-related features (low body weight and BMI) and estrogen-related features (late age of menarche, oligo/amenorrhea) to be significant risk factors for low bone mineral density and bone stress injury in female athletes and exercising women. Nutritional therapy is the recommended first line of treatment to recover bone mass in energy-deficient female athletes and exercising women. If nutritional therapy fails after 12 months or if fractures or significant worsening in BMD occurs, pharmacological therapy may be considered in the form of transdermal estradiol with cyclic oral progestin (not COC).

School-based intervention to prevent overweight and disordered eating in secondary school Malaysian adolescents: a study protocol.

BACKGROUND: Obesity, eating disorders and unhealthy weight-loss practices have been associated with diminished growth in adolescents worldwide. Interventions that address relevant behavioural dimensions have been lacking in Malaysia. This paper describes the protocol of an integrated health education intervention namely 'Eat Right, Be Positive About Your Body and Live Actively' (EPaL), a primary prevention which aimed to promote healthy lifestyle in preventing overweight and disordered eating among secondary school adolescents aged 13-14 years old. METHODS/DESIGN: Following quasi-experimental design, the intervention is conducted in two secondary schools located in the district of Hulu Langat, Selangor, Malaysia. Adolescents aged 13-14 years will be included in the study. A peer-education strategy is adopted to convey knowledge and teach skills relevant to achieving a healthy lifestyle. The intervention mainly promoted: healthy eating, positive body image and active lifestyle. The following parameters will be assessed: body weight, disordered eating status, stages of change (for healthy diet, breakfast, food portion size, screen viewing and physical activity), body image, health-related quality of life, self-esteem, eating and physical activity behaviours; and knowledge, attitude and practice towards a healthy lifestyle. Assessment will be conducted at three time points: baseline, post-intervention and 3-month follow-up. DISCUSSION: It is hypothesized that EPaL intervention will contribute in preventing overweight and disordered eating by giving the positive effects on body weight status, healthy lifestyle behaviour, as well as health-related quality of life of peer educators and participants. It may serve as a model for similar future interventions designed for the Malaysian community, specifically adolescents.

Postoperative marijuana use and disordered eating among bariatric surgery patients.

BACKGROUND: Current literature is scarce in documenting marijuana use after bariatric weight loss surgery (WLS). OBJECTIVES: The objective of this study was to explore the association among marijuana use patterns, disordered eating, and food addiction behaviors in patients 2 years after WLS. SETTING: A university hospital in the United States. METHODS: Participants (N = 50, mean age 28 y, standard deviation = 5.8) were administered a structured assessment that included the Addiction Severity Index, Yale Food Addiction Scale, Eating Disorder Examination Questionnaire, and Disordered Eating Questionnaire. Marijuana use was defined based on the Addiction Severity Index as current use (within 30 d), recent use (use in last year), and increased use (increased use since surgery). Data were analyzed using Fisher's exact tests and linear regression methods adjusting for age, gender, race/ethnicity, time since surgery, and change in body mass index. RESULTS: The majority of the sample was female (76%) and underwent Roux-en-Y gastric bypass (62%). Eighteen percent (18%) of the sample reported current marijuana use; 38% reported recent use; and 21.4% reported increased use post-WLS. A loss of controlled food intake was associated with current (P = .02) and increased post-WLS use (P = .01). Increased use and/or regular marijuana use predicted higher scores on eating disorder subscales compared with respective counterparts (P<.05). Current use did not significantly predict higher scores on the Yale Food Addiction Scale. CONCLUSIONS: Findings indicated marijuana use in post-WLS patients despite recommendations against use. A subgroup of WLS patients may be at risk for disordered eating post-WLS, particularly those who used marijuana before surgery, and should be closely monitored for several years post-WLS.
