Anorexia Nervosa Case Study

1. What was the major purpose or problem described in this article?
The article describes “adolescent girls and adult women with anorexia nervosa have low areal bone mineral density compared to normal-weight controls”. This article also “examine whether reductions in areal bone mineral density predict fracture risk in females and anorexia nervosa”.
2. What, if any, were the hypotheses or research questions?
-In the article they “assessed fracture history and areal bone mineral density in a large group of adolescent females with anorexia nervosa and normal weight control”.
-They “hypothesized that the risk of fracture would increase among the adolescent females with anorexia nervosa as compared to controls and that decreases in areal bone mineral density would associated with history of fracture”.
3.
What sample was used in this research? 418 females out of those 418, 310 of them are active anorexia nervosa and 108 are normal-weight controls. 12-22 years of age were studied cross-sectionally.

4. What types of methods of data collection were used?
Subjects were recruited consecutively through print and electronic advertisements and by referral from regional practitioners in the northeastern United States. Body composition and areal bone mineral density measurements of the whole body, whole body less head, lumbar spine, hip, and radius were assessed by dual-energy x-ray absorptiometry (DXA).
5. What were the results and conclusions of this research?
Anorexia nervosa subjects and normal-weight controls did not differ for chronological age, sexual maturity, or height. The prevalence of prior fracture was 59.8% higher in those with anorexia nervosa compared to controls.
