Abstract

OBJECTIVES:

To measure the changes in subcutaneous and intra-abdominal fat and other metabolic parameters in patients with psychotic disorders, who were newly started on olanzapine treatment and in drug-free controls. The correlation between changes in visceral fat and other metabolic parameters were also studied.

METHODS:

Using a longitudinal open-label design, the 2 studied groups included patients with psychoses (n = 23) [diagnosed as per the 10th edition of the International Classification of Diseases criteria] and drug-free controls (n = 11). Fasting sugar, lipid profile and glycosylated haemoglobin levels were collected at baseline and follow-up. Computed tomographic scans were used to determine changes in the various abdominal fat parameters.

RESULTS:

The patients were significantly younger than the controls, and the former had higher mean subcutaneous fat at baseline. There were statistically significant increases in the subcutaneous fat, intraabdominal fat, weight, waist circumference, hip circumference and body mass index in patients but not in controls. The mean dose of olanzapine (mg/day) correlated significantly with change of intraabdominal fat at follow-up. The change in intra-abdominal fat did not correlate significantly with any of the metabolic parameters studied.

CONCLUSIONS:

Olanzapine produced significant increase in weight and fat parameters. This increase correlated with the dose of olanzapine.
