Abstract

Objectives:

To assess changes in body mass and metabolic profiles in patients with first-episode schizophrenia receiving standardised, assured treatment and to identify predictors and moderators of the effects.

Methods:

We investigated the changes in body mass, fasting blood glucose and lipids in 107 largely antipsychotic naïve, first-episode schizophrenia patients who were treated according to a standard algorithm with long-acting injectable flupenthixol decanoate over 12 months.

Results:

Eighty-three (78%) participants completed the 12 months of treatment, and 104 (97%) received 100% of the prescribed injections during their participation. There were significant increases in BMI (P < .0001), waist circumference (P = 0.0006) and triglycerides (P = 0.03) and decrease in HDL (P = 0.005), while systolic (P = 0.7) and diastolic blood pressure (P = 0.8), LDL (P = 0.1), cholesterol (P = 0.3), and glucose (P = 0.9) values did not change over time. The triglyceride: HDL ratio increased by 91%. Change in BMI was only correlated with change in triglycerides (P = .008). The only significant predictor of BMI increase was non-substance abuse (P = .002).

Conclusions:

The risks of weight gain and metabolic syndrome associated with antipsychotic treatment in first-episode schizophrenia are not restricted to second generation antipsychotics. This is a global problem, and developing communities may be particularly susceptible.
