Anorexia nervosa and anorexic-like syndromes in a population-based female twin sample.

Ellen E. Walters, Kenneth S. Kendler·1995·American Journal of Psychiatry

Abstract

OBJECTIVE: The authors explored the epidemiologic characteristics and risk factors of anorexia nervosa and examined the relationship between narrowly defined anorexia nervosa and anorexia-like syndromes. METHOD: Structured interviews were administered to a population-based sample of 2,163 female twins. Anorexia nervosa was diagnosed by computer algorithm ("computer narrow") and by narrow and broad clinical definitions. RESULTS: Lifetime prevalence estimates of 0.51%, 1.62%, and 3.70% were obtained for the computer narrow, clinical narrow, and clinical broad diagnoses, respectively. Dieting status, greater number of years of parental education, low self-esteem, high levels of neuroticism, and maternal overprotectiveness were significantly associated with anorexia nervosa. Both the pattern of comorbidity and the relationship to epidemiologic risk factors suggested an etiologic continuity between narrowly and broadly defined anorexic syndromes. Co-twins of twins with anorexia nervosa were at significantly higher risk for lifetime anorexia nervosa, bulimia nervosa, major depression, and current low body mass index. Significant comorbidity was found between anorexia nervosa and major depression, bulimia nervosa, generalized anxiety disorder, alcoholism, phobias, and panic disorder. CONCLUSIONS: The authors' analyses support the hypothesis of a spectrum of anorexic-like syndromes in women. These syndromes are familial and share familial etiologic factors with major depression and bulimia nervosa.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
