Trajectories of change in body mass index during inpatient treatment for severe anorexia nervosa during adolescence: predictive factors and hospitalization outcomes.

ABSTRACT:

Background

Weight restoration is one of the main goals of treatment for AN. Weight trajectories derive from various elements including baseline personal characteristics and factors linked to the course of treatment. The aim of our research was to identify different BMI trajectories during inpatient treatment, to examine whether patient characteristics were predictive of the nature of these trajectories, and to examine how they affect hospitalization outcomes.

Methods

The study population consisted of 310 female AN inpatients. To analyse the data, we examined trajectories of change in BMI, using a clustering algorithm: k-means for longitudinal data.

Results

We chose a four-trajectory model. The most common was the A trajectory, which we labelled "severe and compliant"
