A case-control study of family composition in anorexia nervosa

Abstract

Although it is possible that these findings were affected by response bias among control subjects, it is more likely that they are informative with regard to the etiology of anorexia nervosa. Possible etiologic links are discussed in relation to biologic, family, and sociocultural factors.

Parental mental illness and eating disorders in offspring

“…Adjustments were made for maternal age at child's birth, occupational class of the parents, as higher SES has been found to be associated with AN in children, 7 maternal level of education, as higher parental education has been found to be associated with ED in offspring, 19,33,34 family type (single or two parent family) and number of siblings, as there is conflicting evidence from case-control studies regarding whether this may alter risk of ED. [35][36][37] We checked for evidence of interaction between parental mental disorders and any of the potential confounders. Robust variance estimation using mater-nal identification number as a cluster variable was performed to account for having multiple siblings from the same family in the analysis sample.…”

Do eating disorders in parents predict eating disorders in children? Evidence from a Swedish cohort

“…Analysis was stratified by year of birth of the subject. Adjustments were made for maternal age at child's birth, occupational class of the parents (unskilled manual workers, skilled manual workers, lower non‐manual workers, intermediate non‐manual workers, higher non‐manual workers and self‐employed), as higher SES has been found to be associated with AN in children , maternal level of education [9 years or less; 10–12 years; more than 12 years (university)], as higher parental education has been found to be associated with ED in offspring , family type (single‐ or two‐parent family) and number of siblings, as there is conflicting evidence from case–control studies around whether this may alter risk of ED . Robust variance estimation using maternal identification number as a cluster variable was performed to account for having multiple siblings from the same family in the analysis sample.…”

Weight, reference points, and the onset of eating disorders

“…In fact, verbal IQ and cognitive skills may serve as a moderating force against the development of body image concerns (Littleton and Ollendick, 2003). Another control is birth order as the general view is that the first born is likely to face higher risks of developing EDs, though the results of clinical studies are not conclusive (see e.g., Eagles et al, 2005;Goodman et al, 2014). Finally, we include an indicator for parental obesity, because parental obesity has been shown to be a risk factor for the development of BN through promotion of body dissatisfaction (Hill, 2007).…”
