This study examined the degree to which children and adolescents with food allergy accept responsibility for their own care, and the extent to which greater self-management is associated with past history of a life-threatening allergic reaction or anxiety. For children (n = 190), caregiver and patient report of self-management was consistent, but agreement was poor for adolescent dyads (n = 59). History of a life-threatening allergic reaction was associated with greater self-management for children only, while among adolescents, it was associated with greater anxiety. Given that shifting to self-management may be challenging, discussion and preparation about this process is warranted.

Using a repeated measures design, 16 females recorded hunger, distraction, mood and perceived work performance on two consecutive fast days, on two earlier and on two subsequent consecutive non-fast days, during intermittent fasting. Using regression analyses, low positive mood was associated with higher distraction (β = −0.38, p < 0.01), and lower perceived work performance was associated with higher distraction (β = −0.50, p < 0.01) and lower positive mood (β = 0.59, p = 0.01). No associations were found with hunger (largest β = −0.11, p = 0.15). Associations between mood, perceived work performance and distraction but not hunger mirror those found in traditional dieting and suggest no benefit for attention from intermittent fasting-type regimes.

This work aimed to study the effect of guided affective imagery on the irritable bowel syndrome. A total of 15 irritable bowel syndrome patients received guided affective imagery and 19 patients served as controls. Symptom severity and irritable bowel syndrome quality of life were measured at baseline and 8 weeks. Symptom severity decreased following guided affective imagery compared to controls (−1.5 ± 1.9 vs 0.1 ± 1.6, p = 0.04). Irritable bowel syndrome quality of life increased following guided affective imagery compared to controls (12.1 ± 12.5 vs −0.7 ± 16.2, p < 0.01). Guided affective imagery predicted reduced symptom severity (odds ratio = 5.71, p = 0.02) and increased irritable bowel syndrome quality of life (odds ratio = 17.88, p = 0.01). Guided affective imagery combined with dietary modification may be beneficial in the management of irritable bowel syndrome, however larger studies are required.

This study examined the relationships between chronic stress, food cravings, and body mass index. A community-based sample of adults (N = 619) completed a comprehensive assessment battery and heights and weights were measured. Chronic stress had a significant direct effect on food cravings, and food cravings had a significant direct effect on body mass index. The total effect of chronic stress on body mass index was significant. Food cravings partially mediated the relationship between chronic stress and body mass index. These findings are consistent with research that chronic stress may potentiate motivation for rewarding substances and behaviors and indicate that high food cravings may contribute to stress-related weight gain.

The objective of this study was to analyse emotional distress and concerns related to body image in 712 normal-weight and overweight adolescent girls. A total of 12.3 per cent of the normal-weight girls and 25 per cent of the overweight girls showed extreme weight-control behaviours. In normal-weight adolescents, their engagement in extreme weight-control behaviours was associated with high levels of somatic symptoms, a drive for thinness and control over eating. In overweight girls, high levels of drive for thinness and anxiety were associated with extreme weight-control behaviours. Finally, the implications for preventive and therapeutic programmes are discussed.

This study examined self-reported staging for the goal of eating a low-fat diet and several specific dietary consumption behaviors to understand better readiness for dieting. Self-assessed motivation, food frequency measures, and psychosocial variables were obtained from 2057 low-income women enrolled in the Maryland Food for Life Program. Results indicated that staging of specific dietary consumption behaviors was significantly related to staging for the global goal of eating a low-fat diet. Women evaluate their motivation about eating low-fat diets based on perceived efforts and specific activities related to dietary consumption with important implications for dietary behavior change measurement and interventions.

This study explored self-compassion as a mediator between body dissatisfaction, social comparison based on body image and quality of life in 662 female college students. Path analysis revealed that while controlling for body mass index, self-compassion mediated the impact of body dissatisfaction and unfavourable social comparisons on psychological quality of life. The path model accounted for 33 per cent of psychological quality of life variance. Findings highlight the importance of self-compassion as a mechanism that may operate on the association between negative body image evaluations and young women’s quality of life.

A total of 77 children (34 boys, 43 girls, mean age ± standard deviation = 9 ± 1 years) participated in this study; 46 children (intervention) undertook a 12-week school gardening programme and 31 children acted as controls. Measures of the Theory of Planned Behaviour and fruit and vegetable consumption were taken pre- and post-intervention. Repeated measures analysis of variance and hierarchical regression analysis indicated that the intervention group increased daily consumption of fruits and vegetables and increased intentions, attitudes, norms, and perceived behavioural control related to fruit and vegetable consumption. Attitudes, norms and perceived behavioural control significantly predicted changes in fruit and vegetable consumption.

This study examined the association of weight perception and weight satisfaction with body change intentions and weight-related behaviours in 928 overweight adolescents (aged 11–18 years, 44% female). Accurate perception of weight was associated with trying to lose weight and inaccurate perception was associated with trying to gain muscle. Weight dissatisfaction was associated with trying to lose weight and gain muscle. Accurate weight perception and weight dissatisfaction were not associated with healthy weight-related behaviours. Awareness of overweight and body dissatisfaction may be detrimental to the adoption of healthy weight-control behaviours. Interventions with overweight adolescents should encourage body satisfaction, rather than promoting awareness of overweight.

We examined whether there is a relationship between trans fatty acid intakes and emotion regulation, mediated by positive or negative affect. Archival data on 1699 men and 3293 women were used to measure trans fatty acid intake at baseline, positive, and negative affects and emotion regulation at follow-up. Higher trans fatty acid intake related to subsequent difficulties with emotional awareness (p = 0.045), clarity (p = 0.012), and regulation strategies (p = 0.009). Affect mediated these relationships. Lower trans fatty acid intake associated with increased positive and decreased negative affects which, in turn, associated with improved emotion regulation. Trans fatty acid intakes may be associated with subsequent ability to regulate emotions.

The foods we eat have substantial impact on our health, and excessive food intake is associated with numerous long-term health conditions. It is therefore essential to understand the factors influencing this crucial health behavior. Research has identified sleep problems as one such factor; however, little research has examined how sleep problems impact food intake. Using a multisystemic perspective, this article proposes a variety of ways in which sleep problems likely increase food intake and illustrates the need for research to empirically examine these underlying mechanisms. Such research would have important treatment implications for health conditions often treated with dietary interventions.

A Short Message Service programme was adapted to monitor three health behaviours and provide supportive feedback. The study aimed to evaluate the effectiveness of the programme to increase fruit/vegetable consumption and physical activity and to decrease screen time. A total of 139 Portuguese children, aged 8–10 years, grouped by classroom, were randomly assigned to an intervention (8 weeks of monitoring/feedback) or a control condition. Participants had their key behaviours assessed at baseline, post-intervention and follow-up. A three-level hierarchical linear model was developed. Results showed that the monitoring and feedback programme significantly increased fruit and vegetable consumption over time.

This study examined weight status and dietary restraint among same-sex couples using Actor–Partner Interdependence Models. Body mass indices and restrained eating behaviors (i.e., cognitive dietary restraint, uncontrolled eating, and emotional eating) were assessed for members of 144 same-sex couples (72 lesbian and 72 gay couples; mean age = 33.74 years, standard deviation = 11.27 years). Results indicated that both men and women who were relatively heavy and who had relatively thin partners were at particular risk of engaging in restrained eating. These findings extend our understanding of partner comparison processes within the context of same-sex relationships in determining men and women’s eating behaviors.

The modelling of sub-clinical eating disorders and emotive responses to food between mothers and their early adolescent daughters was investigated. Twenty dyads viewed images of food and rated their levels of happiness, fear and disgust. Results suggest similarities between mothers’ and daughters’ emotive responses, but the exact nature of this relationship differed across food type and response type. Disordered eating was only related to responses to the low-calorie foods. Furthermore, mother’s eating disorders symptoms were related to concerns about shape and weight in the daughters (all ps < .05). These results suggest a transmission of emotive responses to food within the dyad which may inform family-based intervention efforts in the prevention of eating disorders in young women.

We aimed to assess the association of several risk factors for eating disturbances in adolescents. Participants were 448 girls and boys aged 12–15 years. Being female, higher body mass index, internalisation of standard of appearance, perfectionism, body dissatisfaction, number of lifetime addictive behaviours and lower self-esteem were associated with higher eating disturbance scores, whereas frequency of sedentary behaviours and physical activity were not (R² ⩾ 41%). Findings suggest the need to guide prevention efforts towards the broad spectrum of individual potentially modifiable factors. A non-specific comprehensive perspective may be adequate to prevent problems related to weight, body image and drug use.

The study investigated self-concept in food-allergic youths and matched healthy controls. Global and domain-specific self-concepts were assessed in 154 participants (9–19 years) using the Multidimensional Self-Concept Scale. Statistical analysis assessed differences between the two samples and effects of asthma, dermatitis, age, and gender among patients. Significant differences were found for Total Scale score and for Competence and Physical scores. Patients showed clinically problematic self-concepts in Global, Competence, and Family domains. Age was found to be associated with the Total score. Health professionals should consider food-allergic patients’ personality development. Further studies could examine disease-specific consequences and interventions.

Qualitative studies examining gender differences of eating disorder prevention programmes are scarce. We aimed to evaluate gender differences in adolescents who participated in a larger study on effectiveness of a disordered eating prevention programme. Perceptions of eating, female and male aesthetic models, media influences, prevention programmes and emerging topics from 12 school-going boys who received a media-literacy programme (n = 4), media-literacy plus nutrition-awareness programme (n = 4) or neither (n = 4) were explored using Interpretative Phenomenological Analysis and compared with previous results in girls. Findings suggest that the prevention programme is effective for both genders. Gender differences and consumer-culture influences may be considered in future interventions.

This study explored the prevalence of and motivations behind ‘drunkorexia’ – restricting food intake prior to drinking alcohol. For both male and female university students (N = 3409), intentionally changing eating behaviour prior to drinking alcohol was common practice (46%). Analyses performed on a targeted sample of women (n = 226) revealed that food restriction prior to alcohol use was associated with greater symptomology than eating more food. Those who restrict eating prior to drinking to avoid weight gain scored higher on measures of disordered eating, whereas those who restrict to get intoxicated faster scored higher on measures of alcohol abuse.

This study aimed to extend the literature by examining several psychological factors (i.e. depression, anxiety, and stress) in relation to binge eating. Data were collected via online surveys from a community sample of men and women of diverse backgrounds. The main study hypotheses were supported, indicating a unique relation between anxiety and binge eating, and between stress and binge eating, independent of the impact of depression. Gender differences are discussed. The results of this study suggest a need for a more detailed examination of negative affect in binge eating. Furthermore, the role of anxiety may be important for future research.

This experiment explored consequences of two common lay theories about the diet–disease link: nutrient-centrism, the belief that nutrients (e.g. potassium) are crucial to staving off disease, and whole-food centrism, the belief that whole foods (e.g. bananas), containing these nutrients in their natural context, are most beneficial. Depicting an individual’s diet in terms of nutrients rather than whole foods containing these nutrients reduced the perceived likelihood that the individual would experience leading diet-related diseases (e.g. heart disease, diabetes). Although nutrition experts increasingly emphasize the health benefits of natural whole foods, people nevertheless appear to privilege nutrients when estimating disease risks.

Qualitative and quantitative studies were conducted to explore the effect of front-of-pack nutrition labels on the perceived healthfulness of food products. Consumers were found to hold beliefs about colours and their fit to product categories that influence the assessment process. Consumers associate certain colours with product healthfulness. Yellow, blue, green and red were found to be evocative of health. Heather, pink and celadon suggested an artificial thus unhealthful product. The impact of labels on healthfulness assessment was observed only in the unhealthful category. The findings show the complexity of psychological processes in the perception of food healthfulness.

This study aimed to investigate the relationship between Type D and dietary intake and to determine whether this relationship is mediated by coping. In a cross-sectional study, 187 healthy participants completed a self-report questionnaire measuring Type D personality, dietary intake and coping. Results showed that Type D was associated with maladaptive coping and significantly less healthy food intake, including more consumption of fat and sugar, and significantly less consumption of fruit and vegetables. Regression analyses showed that this relationship was partially mediated by coping. The results suggest that Type D personality may represent a risk factor for unhealthy eating.
