Abstract

Background

Body image distortions are a core feature of anorexia nervosa (AN). We, and others, previously reported abnormalities in adipose tissue distribution after acute weight restoration in adult women with AN compared with body mass index–matched healthy control women. Whether these abnormalities persist over time remains unknown.

Objectives

We aimed to 1) replicate previous findings that showed preferential central accumulation of adipose tissue in recently weight-restored AN women compared with control subjects, 2) describe the change within patients with longer-term (1-y) weight maintenance, and 3) compare adipose tissue distribution after 1-y maintenance with that of control subjects.

Design

Body composition and adipose tissue distribution were assessed by whole-body magnetic resonance imaging in women with AN shortly after weight normalization (n = 30) and again 1 y after hospital discharge (n = 16) and in 8 female control subjects at 2 time points.

Results

With acute weight restoration, AN patients had significantly greater visceral and intermuscular adipose tissue compared with control women [visceral: 0.75 ± 0.26 compared with 0.51 ± 0.26 kg in AN patients and controls, respectively (P = 0.02); intermuscular: 0.46 ± 0.17 compared with 0.29 ± 0.13 kg in AN patients and controls, respectively (P = 0.01)]. With maintenance of normal weight for ≈1 y, visceral adipose tissue distribution in AN patients was not different from that in healthy control subjects.

Conclusions

In adult women with AN, normalization of weight in the short term is associated with a distribution of adipose tissue that is consistent with a central adiposity phenotype. This abnormal distribution appears to normalize within a 1-y period of weight maintenance. This research was registered at clinicaltrials.gov as NCT 00271921 and NCT 00368667.
