Introduction: Restrained, emotional and intuitive eating were examined in relation to each other and as correlates of participants’ weight status, body image and self-esteem. In some past research, restrained and emotional eating have been associated with higher weight status and poorer mental health, while intuitive eating is more frequently linked to lower weight status and more positive well-being. However, these eating styles have rarely been examined together and never in a large cross-country sample. Method: Six-thousand two-hundred and seventy-two (6272) emerging adults (M age = 21.54 years, SD = 3.13) completed scales from the Three-Factor Eating Questionnaire, the Eating Disorders Examination Questionnaire, the Intuitive Eating Scale-2, the Multidimensional Body Self Relations Questionnaire, the Rosenberg Self-Esteem Scale, and provided weight and height information that was used to calculate body mass index (BMI). Participants resided in Australia, Belgium, Canada, China, Italy, Japan, Spain and the United States and provided information using an online survey. Results: Path analyses for the entire sample revealed significant pathways between higher intuitive eating and higher body satisfaction and self-esteem, and lower BMIs among participants. Higher levels of restrained and emotional eating were associated with lower body satisfaction and self-esteem, and higher BMIs among participants. Minor cross-country differences were evident in these patterns of relations, but intuitive eating emerged as a consistent predictor across countries. Conclusion: Overall, findings suggest that efforts should be made to increase intuitive eating among emerging adults and to support individual and macrolevel interventions to decrease restrained and emotional eating behaviours.

Objective: This study examined the utility of a biopsychosocial model to explain both higher body mass index (BMI) and disordered eating. The study was designed to examine the predictors of higher BMI and a number of measures of disordered eating (dietary restraint, drive for muscularity, drive for thinness, binge eating, and compensatory behaviour). Method: Young adults (N = 838) recruited from seven countries, grouped into four regions (Europe, North American countries, Australia, Japan), completed an online survey, with each completion being 12 months apart. The survey included assessments of BMI and disordered eating, and a range of biological, psychological and sociocultural factors expected to predict both outcomes. Results: Results revealed unique patterns of association between predictors and BMI as well as different measures of disordered eating in the four geographical regions. Conclusions: The findings identify the specific nature of biopsychosocial factors that predict both higher BMI and different aspects of disordered eating. They also demonstrate that caution needs to be exercised in generalising findings from one country to other countries.

Purpose: Disordered eating attitudes and behaviors (DEAB) in childhood have been prospectively associated with eating disorders and obesity in adolescence. Therefore, evaluating DEAB in children with a reliable, sensitive and well-adapted scale is very important. The Children’s Eating Attitudes Test (ChEAT) is one of the most popular measuring tools for DEAB in children, but no French version is available. Moreover, while completion time is an important factor to be considered when working with children, only one recent study proposed a shorter version of the ChEAT. Taking the previous works of Murphy and colleagues (2019) as a starting point, the current study aimed to provide the first French-speaking validated 14-item short version of the ChEAT. Methods: A sample of 1092 boys and girls aged between 8 and 12 years old were recruited in two urban areas in the province of Quebec, Canada. They completed the ChEAT, and their height and weight were measured at school. Factorial structure and internal consistency were assessed. Results: After the initial factorial analysis, two “vomiting (or purging)” items were yielded as problematic and were thus removed from the analysis. The remaining 12 items provided a good fit to the data and a good internal consistency. Moreover, the factorial structure was proved to be invariant across sexes. Conclusion: This study is the first to provide a French assessment of DEAB in elementary school children. The French short version of the ChEAT provided a quick and reliable assessment for DEAB with non-clinical children population and could be used as a screening tool, even though no cut-off was established yet. Level of evidence: Cross-sectional, descriptive study, Level V.

Background: Being the target of peer victimization is frequent among children categorized as overweight and obese and is thought to play a central role in disordered eating behavior development. In accordance with a previous theoretical model, this cross-sectional study aimed to replicate among children the mediating role of weight-related victimization from peers and body dissatisfaction in the association between body mass index (BMI) and children's disordered eating attitudes and behaviors (CDEAB), while also taking into account the contribution of parents' disordered eating attitudes and behaviors (PDEAB). Methods: Participants were 874 children aged between 8 and 12 years old who were recruited in elementary schools. Height and weight were measured and used to calculate BMI. Self-reported questionnaires were used to measure weight-related victimization, body dissatisfaction, CDEAB and PDEAB. Results: For both girls and boys, a path analysis showed no direct effect of BMI on CDEAB, but a significant indirect effect was found, indicating that weight-related victimization and body dissatisfaction mediated this relationship. In addition, the indirect effect of weight-related victimization and body dissatisfaction remained significant even when controlling for PDEAB. Conclusion: While weight itself appears to be insufficient to explain CDEAB, weight-related victimization may lead children to see their weight as problematic and develop disordered attitudes and behaviors toward eating. This suggests that weight-related victimization from peers and body dissatisfaction must be taken seriously and that preventive and intervention efforts must be pursued.

The Tambora eruption (1815 AD) was one of the major eruptions of the last two millennia and has no equivalents over the last two centuries. Here, we collected an extensive network of early meteorological time series, climate simulation data and numerous, well-replicated proxy records from Eastern Canada to analyze the strength and the persistence of the Tambora impact on the regional climate and forest processes. Our results show that the Tambora impacts on the terrestrial biosphere were stronger than previously thought, and not only affected tree growth and carbon uptake for a longer period than registered in the regional climate, but also determined forest demography and structure. Increased tree mortality, four times higher than the background level, indicates that the Tambora climatic impact propagated to influence the structure of the North American taiga for several decades.We also show that the Tambora signal is more persistent in observed data (temperature, river ice dynamics, forest growth, tree mortality) than in simulated ones (climate and forest-growth simulations), indicating that our understanding of the mechanisms amplifying volcanic perturbations on climates and ecosystems is still limited, notably in the North American taiga.
