Description of intervention(s) / exposure
Nil interventions - all subjects will have routine clinical care.
Mostly they are inpatients for the first 4 weeks and will have baseline, 1, 2 and 4 week bloods collected to measure appetite peptides. Then they attend outpatients at roughly monthly intervals until stable. We will collect blood samples to measure appetite peptides at the outpatient visits most closely approximating 8, 16 and 26 weeks and 12 months..
We will observe weight regain and maintenance over the study period. Weight will be measured each visit with scales to the nearest 0.1kg, height will be assessed by stadiometer at first visit.

Outcomes
Primary outcome [1] 298131 0
Change in appetite peptides in relation to weight regain. The hormones will be assessed by ELISAs. Weight change will be assessed as above using digital scales recorded to the nearest 0.1kg.
Timepoint [1] 298131 0
Change from baseline to 12 months from initial refeeding.
Secondary outcome [1] 323243 0
Changes in appetite hormones from baseline to other time points (i.e. not 12 months).
These will be assessed by serum assay.
Timepoint [1] 323243 0
2, 4, 8, 16 weeks, 6 months from initial refeeding admission

Statistical methods / analysis
Paired testing comparing baseline to the time point. We estimate that 50 subjects tested at 12 months should be sufficient to have >80% power to detect differences of clinically relevant magnitude at the p<0.05 level. These would be >10% change in absolute results. Because of the age and relatively high mobility of the participant population, it is likely that many subjects will not have 12 month samples collected, hence the larger number of intake subjects (i.e. up to 200).

Summary
Brief summary
We hypothesise that people with anorexia requiring hospital admission for treatment will have abnormalities in appetite peptides, and that these may not return to normal even with weight restoration. A secondary hypothesis is that we may be able to identify a predictor of good outcome at 1 year.
This study will collect serial blood samples in people admitted to Westmead Hospital for treatment of anorexia nervosa.
Blood will be collected prior to refeeding and at the visits closest to 2, 4, 8, 16 weeks, 6 and 12 months.
