“…When research has been conducted, it has typically focused on BED, where results suggest that binge eating may develop before dieting for early onset BED, and after dieting for later‐onset BED . The literature on BN is much smaller and no significant differences have been found between early and later‐onset cases . However, studies to date have tended to compare groups on prior exposures (e.g., rates of childhood obesity) without examining prospective predictors of risk for each group (e.g., whether obesity predicts risk for early and later‐onset cases).…”

“…The bulk of bulimia risk research has been conducted with adolescent girls around the peak age of onset, which is estimated to be age 16 for binge eating (Day, Schmidt, Collier, Perkins, Van Den Eynde et al, 2001; le Grange & Loeb, 2007; Stice, Marti, & Rohde, 2013) and age 18 for purging (Stice, Killen, Hayward, & Taylor, 1998). Consistent with these estimates for the emergence of these symptoms, Stice et al (2013) found the peak age of onset for bulimia nervosa (BN) to be between 16 and 20 years of age, although the age of onset for BN may be decreasing (Smink, van Hoeken, & Hoek, 2012).…”

To investigate whether there are different patterns of development for binge eating and purging behavior among pre-adolescent and early adolescent girls, we conducted trajectory analyses of those behaviors in 938 girls across eight waves of data from the spring of 5th grade (the last year of elementary school) through the spring of 9th grade (the first year of high school). Analyses revealed four separate developmental trajectories for binge eating behavior (labeled none, increasing, decreasing, and high steady) and three separate developmental trajectories for purging behavior (labeled none, dabble, and increasing). Fifth grade scores on risk factors that were both transdiagnostic (negative affect and negative urgency) and eating disorder specific (expectancies for reinforcement from eating and from thinness) differentiated among the trajectory groups, in some cases before the groups differed in the target behaviors. These findings are the first, to our knowledge, to examine developmental trajectories for bulimic symptom onset in youth as young as elementary school. Clinical implications are discussed.

“…However, the biological, psychological, and sociocultural milieu varies dramatically over the lifespan. Research suggests that ED risk factors vary across development such that individuals who develop EDs at different ages appear to have different risk factors [98] as well as distinct etiological pathways [99]. For example, some childhood risk factors such as parent-perceived child overweight predict early, but not lateronset EDs [98].…”

The Diagnostic and Statistical Manual of Mental Disorders (i.e., DSM-5) currently recognizes three primary eating disorders: anorexia nervosa, bulimia nervosa, and binge eating disorder. The origins of eating disorders are complex and remain poorly understood. However, emerging research highlights a dimensional approach to understanding the multifactorial etiology of eating disorders as a means to inform assessment, prevention, and treatment efforts. Guided by research published since 2011, this review summarizes recent findings elucidating risk factors for the development of eating disorders across the lifespan in three primary domains: (1) genetic/biological, (2) psychological, and (3) socio-environmental. Prospective empirical research in clinical samples with full-syndrome eating disorders is emphasized with added support from cross-sectional studies, where relevant. The developmental stages of puberty and the transition from adolescence to young adulthood are discussed as crucial periods for the identification and prevention of eating disorders. The importance of continuing to elucidate the mechanisms underlying gene by environmental interactions in eating disorder risk is also discussed. Finally, controversial topics in the field of eating disorder research and the clinical implications of this research are summarized.
