Mediating role of disordered eating in the relationship between screen time and BMI in adolescents: longitudinal findings from the Research on Eating and Adolescent Lifestyles (REAL) study

AbstractObjective:This study investigated whether the duration and type of screen time (ST) (TV viewing, recreational computer use, video gaming) is longitudinally associated with z-BMI and if these relationships are mediated by disordered eating (emotional, restrained).Design:At baseline, participants were n 1197 (T1; 60 % female) adolescents (mean age = 13·51 years) who completed surveys over 2 years. ST was assessed by a self-reported measure created by the investigative team, while emotional and restrained eating was measured by the Dutch Eating Behaviour Questionnaire (DEB-Q). Height and weight were objectively measured to quantify z-BMI.Setting:Thirty-one public and two private schools from the region of Ottawa, Canada.Participants:Students in grades 7–12.Results:Parallel multiple mediation analyses revealed that more time spent watching TV at baseline is associated with higher z-BMI at T3 (total effect; B = 0·19, se = 0·07, P = 0·01, 95 % CI 0·05, 0·34), but no relationships were observed for total ST exposure or other types of ST and z-BMI. Disordered eating did not mediate the positive association between baseline TV viewing and z-BMI at T3.Conclusions:TV viewing was longitudinally associated with higher z-BMI in a community-based sample of adolescents, but disordered eating behaviours did not mediate this relationship. However, other non-pathological eating behaviours may mediate the association between ST and obesity and warrant further investigation. Finding suggests that targeting reduction in youth’s TV viewing may be an effective component in the prevention of childhood obesity.

The Relationship

Previous studies have found some risk factors of cyberbullying. However, little is known about how mother phubbing may influence adolescent cyberbullying, and the mediating and moderating mechanisms underlying this relationship. “Phubbing,” which is a portmanteau of “phone” and “subbing,” refers to snubbing other people and focus on smartphones in social interactions. This study examined whether mother phubbing, which refers to being phubbed by one’s mother, would be positively related to adolescent cyberbullying, whether perceived mother acceptance would mediate the relationship between mother phubbing and adolescent cyberbullying, and whether emotional stability would moderate the pathways between mother phubbing and adolescent cyberbullying. The sample consisted of 4,213 Chinese senior high school students (mean age 16.41 years, SD = 0.77, 53% were female). Participants completed measurements regarding mother phubbing, cyberbullying, perceived mother acceptance, and emotional stability. The results indicated that mother phubbing was positively related to cyberbullying, which was mediated by perceived mother acceptance. Further, moderated mediation analyses showed that emotional stability moderated the direct path between mother phubbing and cyberbullying and the indirect path between mother phubbing and perceived mother acceptance. This study highlighted the harmful impact of mother phubbing on adolescents by showing a positive association between mother phubbing and adolescent cyberbullying, as well as the underlying mechanisms between mother phubbing and adolescent cyberbullying.

A Prospective Study

Aim:To investigate the role of perfectionism in the development of disordered eating behaviours.Method:382 female university students completed the Hewitt & Flett MPS and the EAT-40 at baseline, one year after (T1) and two years later (T2).Results:Perfectionism at baseline was significantly associated with long-term abnormal eating attitudes/behaviours. Self-Oriented Perfectionism (SOP) and Socially Prescribed Perfectionism (SPP) were significant predictors of disordered eating behaviours. SOP at baseline was predictive of diet concerns, at T1 and T2. Baseline SPP was correlated with overall eating disturbance at T1 and T2. Regression analysis revealed that only SPP was a significant predictor of bulimic behaviours and social pressure to eat at T1, but not at T2.Conclusion:Our findings contribute to a more clear understanding of the association between perfectionism and eating disorders. SOP and SPP were prospectively associated with abnormal eating attitudes/behaviours and SOP was found to be predictive of diet concerns.

AbstractObjective:To identify whether picky eating during childhood is associated with dietary intake, weight status and disordered eating behaviour during young adulthood.Design:A population-based study using data from young adults who responded online or by mail to the third wave of the Project EAT (Eating and Activity in Teens and Young Adults) study in 2008–2009. Participants retrospectively reported the extent to which they were a picky eater in childhood, sociodemographic characteristics, disordered eating behaviours, usual dietary intake, and weight and height.Setting:Participants were initially recruited in the Minneapolis/St. Paul metropolitan area of Minnesota, USA, in 1998–1999.Participants:The analytic sample included 2275 young adults (55 % female, 48 % non-Hispanic White, mean age 25·3 (sd 1·6) years).Results:Young adults who reported picky eating in childhood were found to currently have lower intakes of fruit, vegetables and whole grains, and more frequent intakes of snack foods, sugar-sweetened beverages and foods from fast-food restaurants. No associations were observed between picky eating in childhood and young adults’ weight status, use of weight-control strategies or report of binge eating.Conclusions:While young adults who report picky eating during childhood are not at higher risk for disordered eating, those who were picky eaters tend to have less healthy dietary intake. Food preferences and dietary habits established by picky eaters during childhood may persist into adulthood.

Mediating Role

Studies of people with eating disorders (ED) have indicated that meaning in life is negatively associated with psychopathology, suicide risk, and emotional instability in people with ED. The aim of this study was to analyze the mediating role of meaning in life and its dimensions in the relationship between body dissatisfaction and the symptoms of ED, and to provide evidence that supports the meaning making model of eating disorders (MESTA, in Spanish). 292 Participants diagnosed with ED completed the Purpose in Life Test (PIL), the Eating Attitudes Test (EAT), and the Multidimensional Body-Self Relations Questionnaire (MBSRQ-AS). Multiple mediation analyses were performed. Meaning in life was a mediator between body dissatisfaction and ED psychopathology. The dimension of Satisfaction and meaning in life had a greater mediating role. Meaning in life could be an important variable in the maintenance of ED. The MESTA could be a useful model for understanding the psychopathology of ED.

The Relationship

Background.This work examines the relationship between emotional intelligence (EI) and depressive symptomatology in institutionalized older adults, delving into the mechanisms underlying this relationship. Considering that previous evidence of the variation of the EI-depression relationship depending on whether the emotional ability or the perception of that ability is evaluated, a model of multiple mediation was tested in which the dimensions of emotional self-efficacy (ESE) act as mediators in the relationship between ability EI and depressive symptomatology.Methods.The sample consisted of 115 institutionalized older adults (47.82% women; 80.3 ± 7.9 years of age) from the province of Jaén (Spain) who completed a test of ESE, a measure of ability EI, and a self-administered questionnaire of depressive symptoms.Results.The results showed a positive association between older adults’ emotional performance and depressive symptomatology, finding stronger associations with ESE than with EI abilities. In addition, multiple mediation analyses showed that two of the four dimensions of ESE fully mediated the relationship between ability EI and depressive symptoms.Discussion.These findings suggest that older adults’ high levels of emotional competence generate a feeling of ESE which can protect them against depressive symptoms. This work supports the predictive validity of emotional abilities and ESE for the mental health of a group that is particularly vulnerable to depression, institutionalized older adults. The limitations of the work are discussed, and future lines of research were considered.

Objective:This study aimed to investigate the nutrition literacy status of Taiwanese college students and to assess the relationship between nutrition literacy and healthy-eating behaviours.Design:Cross-sectional design with convenience sampling.Setting:Six universities in northern, central and southern Taiwan; both national and private universities were included in each region.Method:A maximum of 220 students was recruited from each university with no more than 45 students from one department. Data were collected using a self-rated nutrition literacy scale and questions about frequency of practising healthy-eating behaviours and demographic information.Results:The mean score for self-rated nutrition literacy was 2.8 (out of 4), and the mean score for healthy-eating behaviours was 3.07 (out of 5). Results of hierarchical regression showed that nutrition literacy explained 17.2% of the total variance of healthy-eating behaviours of college students, controlling for confounding variables.Conclusion:The findings of this study showed that nutrition literacy among college students was not optimal, and there was a positive association between higher levels of nutrition literacy and healthier dietary behaviours. Therefore, identifying methods to increase nutrition literacy among college students is essential to promote healthy-eating behaviours.

Body image and self-perception about weight, irrespective of their actual body mass index, may predispose young females to disordered eating behaviour. A study was conducted to determine body image disturbance, weight perception and body mass index among female college students in Delhi having normal and disordered eating behaviours. The study sample comprised 734 female under-graduate students between 18-21 years from women’s colleges of Delhi University. An interview-cum-questionnaire schedule was used to assess the general profile of subjects and perceptions about their body weight. Adapted Eating Attitudes Test (EAT)-26 and Body Shape Questionnaire (BSQ)-8c was used to determine disordered eating behaviour and body image disturbance among the subjects respectively. Body Mass Index of the subjects was also computed. Findings revealed a significant difference in self-perception about body weight among subjects showing normal and disordered eating behaviours. Higher percentage of subjects from disordered eating group perceived themselves to be either overweight or obese as compared to subjects from normal eating behaviour group.Significantly higher BSQ-8c scores and Body Mass Index were also observed among subjects having disordered eating behaviour. The study indicated that poor body image, self-perception about body weight being high as well as high body mass index played a significant role in occurrence of disordered eating behaviour among female college students in Delhi.The study depicted the urgent need to have appropriate health and nutrition education programmes for female college students to improve their perceptions about body shape and weight to further prevent the occurrence of disordered eating behaviour among them and make them less vulnerable to consequent nutritional problems.

Abstract Recent models of obesity and eating behaviour have implicated both automatic responding to food-related cues and executive functioning in driving dietary choice. This study aimed to relate grazing severity to high weight with and without significant eating disorder features via the effects of inhibition and degree of goal-directed behaviour, in persons with obesity with and without significant eating disorder features compared to healthy controls. Forty-four participants with obesity (43.1% endorsing marked eating disorder features), and 43 healthy-weight age- and sex-matched participants (N = 87; 67.8% female, age = 28.57 (8.70; 18.18–58.34) years, BMI = 29.18 (7.80; 18.65–51.95) kg/m2) completed demographic and eating disorder-related questionnaires, a neuropsychological task of inhibition and an instrumental decision-making task. Bootstrapped serial mediation analyses were performed to examine the effect of group on grazing via goal-directed behaviour and inhibition. While significant differences existed between the groups in terms of inhibition, goal-directed behaviour and grazing severity, the effect of group on grazing severity was not found to be mediated by the degree of behavioural goal-directedness and inhibition. Therefore, :in persons with obesity with or without eating disorder symptoms, putative relationships between a reduced inhibitory profile and/or behaviour that is less flexible and goal-directed and eating behaviours such as grazing, remain unclear.

Background: The Children’s Eating Behaviour Questionnaire (CEBQ) is used with parents to determine the characteristics of eating behaviour of their children and, consequently, children’s propensity to become obese. It has been successfully used mainly in Western countries, but not in Saudi Arabia. In this pilot study, we explored the use of the Saudi version of the CEBQ for preschool children aged 2–6 years in Saudi Arabia, and assessed the associations between eating behaviours and children’s age, gender and relative weight and parental weight. Methods: Parents of 200 Saudi preschool children in Riyadh completed the Saudi version of the CEBQ. Factor analyses on all CEBQ items were performed and differences between genders and age groups were examined. Correlations between children’s BMI z-scores and eating behaviours were analysed using linear regression. Results: The factor analysis revealed an eight-factor solution similar to the theoretical factor structure, with good internal reliability and acceptable correlations between subscales. Boys scored higher than girls on food responsiveness; no difference between age groups was found. Positive associations between BMI z-scores and ‘food approach’ subscales, food responsiveness, enjoyment of food and emotional overeating were found, while ‘food avoidant’ subscales, satiety responsiveness and slowness in eating had inverse relationships with BMI z-scores. Maternal BMI had a positive association with BMI z-scores and food responsiveness. Conclusion: The CEBQ is a valid psychometric tool that can be reliably used to assess eating behaviour characteristics in Saudi preschool children.
