“…In a recent study of 11‐ to 12‐year‐olds, we observed that overweight co‐occurred with DEBs (Larsen, Strandberg‐Larsen, Olsen, Micali, & Nybo Andersen, ). This is in line with increasing evidence showing that childhood overweight predicts later onset of DEBs (Forrester‐Knauss, Perren, & Alsaker, ; Micali et al, ; Munkholm et al, ; Neumark‐Sztainer et al, ; Neumark‐Sztainer, Paxton, Hannan, Haines, & Story, ; Reed, Micali, Bulik, Smith, & Wade, ; Stice, Presnell, & Spangler, ; Wiklund et al, ). However, not all research concurs; other studies report no association between childhood body mass index (BMI) and DEBs in early adolescence (Evans et al, ; Gardner, Stark, Friedman, & Jackson, ).…”

Objective To examine how childhood weight trajectories are associated with disordered eating behaviours (DEBs) in early adolescence. Methods Self‐reports on DEBs (fasting, purging, and binge eating) were obtained from 18,337 children in the 11‐year follow‐up of the Danish National Birth Cohort. For this population, birth register information on gestational age and birth weight was categorized into the following: small, appropriate, and large for gestational age. Prospective parent‐reported height and weight data at child ages 1 and 7 years were dichotomized using standardized cut‐offs into non‐overweight and overweight. A 12‐category weight trajectory variable was created, and the associations between weight trajectory and DEBs were estimated using logistic regression. Results In total, 7.0% 11‐ to 12‐year olds reported DEBs. Compared with children born appropriate for gestational age and being non‐overweight at age 1 and 7 years, children born small for gestational age and who were overweight at age 1 and 7 years had a very high risk of disordered eating (OR 7.00; CI [2.57, 19.40]). The statistical analyses revealed, however, that overweight at age 7 years was the main contributor and independently of trajectory increased the risk of disordered eating at age 11–12 years significantly (OR 3.16 CI [2.73, 3.65]). Conclusion Overweight not in the first year of life, but at age 7 years was more predictive for DEBs.

“…Early adolescence is a time when pubertal maturation is prominently on view for others, can be quite varied in onset and presentation, and is often accompanied by weight gain. Just has been found for BMI (Brixval, Rayce, Rasmussen, Holstein, & Due, 2012; Fairburn, Welsh, Doll, Davies, & O'Connor, 1997; Gardner, Brown, & Boice, 2012; Helfert & Warschburger, 2013; Levinson et al, 2013; Wiklund et al, 2018), earlier (i.e., more advanced relative to peers) pubertal maturation has been associated with DE (e.g., Graber, Brooks-Gunn, Paikoff, & Warren, 1994; Haynos, Watts, Loth, Pearson, & Neumark-Stzainer, 2016; Levinson et al, 2013; for reviews see Ricciardelli & Yager, 2016; Striegel-Moore & Cachelin, 1999; Wiklund et al, 2018), appearance dissatisfaction and poorer body image (Rousseau, Rodgers, & Eggermont, 2017; Rosseau, Trekels, & Eggermont, 2018), appearance anxiety (Webb, Zimmer-Gembeck, & Mastro, 2016; Zimmer-Gembeck et al, 2018), and peer teasing or criticism about appearance (Rosseau et al, 2018; Zimmer-Gembeck et al, 2018).…”

Risk factors and temporal patterns of disordered eating differ in adolescent boys and girls: Testing gender-specific appearance anxiety models

et al. 2020

Adolescent dieting and disordered eating (DE) are risks for clinical eating disorders. In this five-wave longitudinal study, we tested gender-specific models linking early risk factors to temporal patterns of DE, considering appearance anxiety as a mediator. Participants were 384 Australian students (age 10 to 13; 45% boys) who reported their purging and skipping meals, experience with appearance-related teasing, media pressure, and appearance anxiety. Parents reported pubertal maturation and height/weight was measured. Gender differences in temporal patterns of DE were found and predictive models were tested using latent-variable growth curve and path models. Boys’ DE was generally stable over time; girls showed stability in purging but an average increase in skipping meals. Peer teasing, media pressure, and pubertal maturation were associated with more elevated initial DE in girls, and pubertal maturation was associated with a steeper increase in DE. For boys, body mass index had a direct positive association with DE. Appearance anxiety was associated with more DE, but there was only one significant indirect effect via anxiety, which was for boys’ pubertal maturation. Findings support the dominant role of social interactions and messages, as well as pubertal maturation, for girls’ DE and the prominence of physical risk factors for explaining boys’ DE.

“…36% of patients with severe restrictive disorders previously had a high and premorbid BMI. This suggests that obesity and overweight may be risk factors for subsequent ED (23,24) with an increased risk of late diagnosis (10 months later in our study) and the development of complications with a worse prognosis (6,25,26).…”

The experience in pediatric patients with eating disorder for 10 years

et al. 2020

Aim: In recent years, there has been a remarkable increase in eating disorders among pediatric patients. The identification of certain clinical profiles allows us to better understand predisposing or triggering factors, as well as disorder prognosis in this age range. Therefore, the main objective of this study is to describe the patterns of pediatric patients with eating disorders to improve the approach of Pediatricians for these early-onset disorders and promote protocolized interventions as an essential tool to improve the health of these children. Methods: A retrospective study of pediatric patients diagnosed with eating disorders from 2009 to 2019 in a third-level pediatric hospital evaluated the demographic, biographical, anthropometric, psychiatric, and clinical characteristics, as well as others related to diagnosis and treatment. Results: Symptoms among children are similar to those experienced by adults and adolescents; however, incomplete forms of the disease are more frequent in children. The main differences between the age groups include a more equitable sex ratio, a shorter time evolution of the disease before diagnosis, less deterioration of overall health state in the first evaluation and a shorter duration of the disorder. Conclusions: The best prognosis in children could be explained by the closer medical follow-up of these patients and their better adherence to treatment, the early intervention of parents and higher dependence on their caregivers in food choices and intake. In addition, greater plasticity for psychological treatment and coordination of the multidisciplinary team in the care process also contributed the observed trend.
