Abstract Background Restrained eating disorder is prevalent worldwide across both ethnic and different cultural groups, and most importantly within the adolescent population. Additionally, comorbidities of restrained eating present a large burden on both physical and mental health of individuals. Moreover, literature is relatively scarce in Arab countries regarding eating disorders, let alone restrained eating, and among adolescent populations; hence, the aim of this study was to (1) validate the Dutch Restrained Eating Scale in a sample of Lebanese adolescents and (2) assess factors correlated with restrained eating (RE), while taking body dissatisfaction as a moderator between body mass index (BMI) and RE. Methods This cross-sectional study, conducted between May and June 2020 during the lockdown period imposed by the Lebanese government, included 614 adolescents aged between 15 and 18 years from all Lebanese governorates (mean age of 16.66 ± 1.01 years). The scales used were: Dutch Restrained Eating Scale, body dissatisfaction subscale of the Eating Disorder Inventory-Second version, Rosenberg Self-Esteem Scale, Beirut Distress Scale (for psychological distress), Hamilton Anxiety Rating Scale and Patient Health Questionnaire (for depression). Results The factor analysis yielded a one-factor solution with Eigen values > 1 (variance explained = 59.65 %; αCronbach = 0.924). Female gender (B = 0.19), higher BMI (B = 0.49), higher physical activity index (B = 0.17), following a diet to lose weight (B = 0.26), starving oneself to lose weight (B = 0.13), more body dissatisfaction (B = 1.09), and higher stress (B = 0.18) were significantly associated with more RE, whereas taking medications to lose weight (B=-0.10) was significantly associated with less RE. The interaction body mass index (BMI) by body dissatisfaction was significantly associated with RE; in the group with low BMI, higher body dissatisfaction was significantly associated with more RE. Conclusions Our study showed that the Dutch Restrained Eating scale is an adapted and validated tool to be used among Lebanese adolescents and revealed factors associated with restrained eating in this population. Since restrained eating has been associated with many clinically-diagnosed eating disorders, the results of this study might serve as a first step towards the development of prevention strategies targeted towards promoting a healthy lifestyle in Lebanese adolescents.

The Impact

BackgroundFew large prospective studies have investigated the impact of body mass index (BMI) on lung function during childhood.MethodsUsing data collected between 2002 and 2013, we analysed associations between BMI status and lung function (assessed by spirometry) from 8 to 16 years, as well as cross-sectional associations with small airway function (impulse oscillometry) at 16 years in the BAMSE cohort (n=2889). At 16 years, cross-sectional associations with local and systemic inflammation were investigated by analysing FENO, blood eosinophils and neutrophils.ResultsOverweight and obesity at 8 years were associated with higher FVC, but lower FEV1/FVC ratio at 8 and 16 years. In boys, but not girls, obesity at 8 years was associated with a further reduction in FEV1/FVC between 8 and 16 years. In cross-sectional analyses, overweight and obesity were associated with higher frequency dependence of resistance (R5–20) and larger area under the reactance curve (AX0.5) at 16 years. Increased blood neutrophil counts were seen in overweight and obese girls, but not in boys. No association was found between BMI status and FENO. Persistent, but not transient, overweight/obesity between 8 and 16 years was associated with higher R5–20 and AX0.5 and lower FEV1/FVC (−2.8% (95% CI −4.1 to −1.2) in girls and −2.7% (95% CI −4.4 to −1.1) in boys) at 16 years, compared with persistent normal weight.ConclusionIn childhood and adolescence, overweight and obesity, particularly persistent overweight, were associated with evidence of airway obstruction, including the small airways.

Shape Concern

- Body dissatisfaction is a central aspect for self-evaluation; pressures to maintain an ideal physique can result in disordered eating habits. In young women, body concern and anxiety related to some parts of it can be expressed through their desire to lose weight. The aim of the study is to analyze the role of some risk factors, such as Body Mass Index (BMI), low self-esteem and sociocultural influences in affecting body dissatisfaction, expressed in terms of distance from an ideal and body concern. Participants are 187 adolescent females aged between 14 and 16. Risk factors taken into consideration seem to have a different effect on the two aspects characterizing dissatisfaction. BMI, self-esteem and internalization of a thin ideal seem to influence the distance perceived from an ideal body; pressure, besides BMI and self-esteem, affect weight and body shape concern. Body shape concern seems to be influenced even by internalization and awareness. It can be observed that such risk factors, in particular BMI, play a different role in adolescents classified as normal weight and underweight.Parole chiave: immagine corporea, insoddisfazione corporea, adolescenti femmine, influenze socioculturali, autostima, indice di massa corporeaKey words: body image, body dissatisfaction, adolescent girls, sociocultural influences, selfesteem, body mass index

Abstract Background. Abnormal body mass index (BMI) has been associated with development of psychopathology. This association in children is well documented, for both overweight and underweight children. However, the association between change in BMI and the development of psychopathology has been less investigated. Aim. To investigate the association between change in BMI between childhood and adolescence and psychopathology in adolescence. Methods. Data from the Growing Up in Ireland cohort were used. We investigated the ’98 cohort (also known as the child cohort) at age 9/13. BMI, defined using internationally recognised definitions as underweight, healthy or overweight, was used as the exposure, and abnormal Strength and Difficulties Questionnaire scores were used as the outcome. Logistic regression was undertaken for the analysis. All analyses were adjusted for confounders. Results. A change to overweight from healthy BMI was significantly associated with increased risk of psychopathology (adjusted OR 1.66; 95% CI 1.19–2.32). Both change from underweight to healthy (adjusted OR 0.12; 95% CI 0.03–0.43) or from overweight to healthy (adjusted OR 0.47; 95% CI 0.79–0.8) was associated with a significantly reduced risk of developing psychopathology. Discussion. As a child’s BMI returns to within the healthy range, their risk of adolescent psychopathology is reduced. Interventions to restore healthy BMI, in both underweight and overweight, children may reduce their risk of adolescent psychopathology.

The objective of this study was to assess whether body dissatisfaction predicted weight loss in terms of an inverted U relationship. It was predicted that women with high and low body dissatisfaction were less likely to lose weight than women with moderate levels of body dissatisfaction. The study also sought to determine if the number of weight loss attempts, success at past weight loss and self-concept predicted percentage of weight loss in women at six months; and to test whether weight loss led to decreased body dissatisfaction and increased self-concept. Women attempting to lose weight (n = 209) were asked to complete a set of questionnaires at two time points. Results show that women with moderate scores on body dissatisfaction lost more weight than women with higher or lower scores, although this association disappeared when Body Mass Index (BMI) was controlled for in the analyses. Low BMI, success of previous weight loss and low personal self-concept predicted weight loss six months later. Women who lost weight reported lower body dissatisfaction and improved self-concept. It was concluded that, assessing for body dissatisfaction, BMI and weight loss history in the context of primary health settings, may aid in identifying women able to motivate themselves to successfully lose weight in a self-directed manner.

Polygenic Scores

Background: Disordered eating (DE) is common and is associated with body mass index (BMI). We investigated whether genetic variants for BMI were associated with DE. Methods: BMI polygenic scores (PGS) were calculated for participants of the Avon Longitudinal Study of Parents and Children (ALSPAC; N = 8654) and their association with DE tested. Data on DE behaviors (e.g., binge eating and compensatory behaviors) were collected at ages 14, 16, 18 years, and DE cognitions (e.g., body dissatisfaction) at 14 years. Mediation analyses determined whether BMI mediated the association between the BMI-PGS and DE. Results: The BMI-PGS was positively associated with fasting (OR = 1.42, 95% CI = 1.25, 1.61), binge eating (OR = 1.28, 95% CI = 1.12, 1.46), purging (OR = 1.20, 95% CI = 1.02, 1.42), body dissatisfaction (Beta = 0.99, 95% CI = 0.77, 1.22), restrained eating (Beta = 0.14, 95% CI = 0.10, 1.17), emotional eating (Beta = 0.21, 95% CI = 0.052, 0.38), and negatively associated with thin ideal internalization (Beta = −0.15, 95% CI = −0.23, −0.07) and external eating (Beta = −0.19, 95% CI = −0.30, −0.09). These associations were mainly mediated by BMI. Conclusions: Genetic variants associated with BMI are also associated with DE. This association was mediated through BMI suggesting that weight potentially sits on the pathway from genetic liability to DE.
