Abstract

Anorexia nervosa (AN) is prevalent in adolescents and is associated with decreased bone mineral accrual at a time critical for optimizing bone mass. Low BMD in AN is a consequence of nutritional and hormonal alterations, including hypogonadism and low estradiol levels. Effective therapeutic strategies to improve BMD in adolescents with AN have not been identified. Specifically, high estrogen doses given as an oral contraceptive do not improve BMD. The impact of physiologic estrogen doses that mimic puberty on BMD has not been examined. We enrolled 110 girls with AN and 40 normal-weight controls 12 to 18 years of age of similar maturity. Subjects were studied for 18 months. Mature girls with AN (bone age [BA] ≥15 years, n = 96) were randomized to 100 µg of 17β-estradiol (with cyclic progesterone) or placebo transdermally for 18 months. Immature girls with AN (BA < 15 years, n = 14) were randomized to incremental low-dose oral ethinyl-estradiol (3.75 µg daily from 0 to 6 months, 7.5 µg from 6 to 12 months, 11.25 µg from 12 to 18 months) to mimic pubertal estrogen increases or placebo for 18 months. All BMD measures assessed by dual-energy X-ray absorptiometry (DXA) were lower in girls with AN than in control girls. At baseline, girls with AN randomized to estrogen (AN E + ) did not differ from those randomized to placebo (AN E–) for age, maturity, height, BMI, amenorrhea duration, and BMD parameters. Spine and hip BMD Z-scores increased over time in the AN E+ compared with the AN E– group, even after controlling for baseline age and weight. It is concluded that physiologic estradiol replacement increases spine and hip BMD in girls with AN. © 2011 American Society for Bone and Mineral Research

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.
