ABSTRACT To identify predictors of becoming eating disordered among adolescents.
Prospective cohort study.
Self-report questionnaires.
Girls (n = 6916) and boys (n = 5618), aged 9 to 15 years at baseline, in the ongoing Growing Up Today Study (GUTS). Main Exposures Parent, peer, and media influences.
Onset of starting to binge eat or purge (ie, vomiting or using laxatives) at least weekly.
During 7 years of follow-up, 4.3% of female subjects and 2.3% of male subjects (hereafter referred to as "females" and "males") started to binge eat and 5.3% of females and 0.8% of males started to purge to control their weight. Few participants started to both binge eat and purge. Rates and risk factors varied by sex and age group (<14 vs > or =14 years). Females younger than 14 years whose mothers had a history of an eating disorder were nearly 3 times more likely than their peers to start purging at least weekly (odds ratio, 2.8; 95% confidence interval, 1.3-5.9); however, maternal history of an eating disorder was unrelated to risk of starting to binge eat or purge in older adolescent females. Frequent dieting and trying to look like persons in the media were independent predictors of binge eating in females of all ages. In males, negative comments about weight by fathers was predictive of starting to binge at least weekly.
Risk factors for the development of binge eating and purging differ by sex and by age group in females. Maternal history of an eating disorder is a risk factor only in younger adolescent females.

    ABSTRACT: OBJECTIVE: To analyze scientific evidence about the influence of the family group on anorexia nervosa (AN) symptoms. METHODS: Systematic review of the literature published between 2000 and 2012, using the databases PubMed, CINAHL, PsycINFO, Lilacs and the descriptors: "eating disorders", "family relations", "intergenerational relations" and "mother-child relations". RESULTS: Based on the inclusion and exclusion criteria, 20 publications were selected and their full version was analyzed. Most of the papers focus on women diagnosed with eating disorders (ED) or risky eating behavior, have a quantitative design and use standardized scales for data collection. Evidence Level 4 was predominant, which corresponds to studies with a non-experimental design, like correlational and qualitative descriptive studies, or case studies. The evidences found indicate that family relations significantly affect both the development and maintenance of ED symptoms. Eating and food patterns are transmitted between generations, as well as non-elaborated aspects of maternal psychic functioning. CONCLUSIONS: Studies suggest the need for a broader care focus, so as to include family members in treatment, as well as to incorporate the findings related to intergenerational psychic transmission to guide the planning and qualification of the care offered in case of ED.

    ABSTRACT: BACKGROUND: There is a large body of evidence indicating that eating disorders (EDs) are characterized by particular neuropsychological profiles. We aimed to further explore whether impairments in neuropsychological functioning previously found in ED groups are present prior to onset, or are secondary to the disorder. Method This is the first study to explore neuropsychological functioning in children born to a mother with a lifetime ED, who are therefore at high risk of developing an ED, in a large cohort sample. We investigated intelligence and attention at age 8 years (n = 6201) and working memory (WM) and inhibition at age 10 years (6192) in children who are at high risk of developing an ED, compared to children who are not. RESULTS: The children of women with lifetime anorexia nervosa (AN) showed high full-scale and performance IQ, increased WM capacity, better visuo-spatial functioning, and decreased attentional control. The children of women with lifetime bulimia nervosa (BN) showed comparatively poor visuo-spatial functioning. CONCLUSIONS: Our findings suggest that high intelligence, increased WM capacity and impaired attentional control might be intermediate phenotypes on the pathway between genetic vulnerability and the development of an ED.
