However, antipsychotic (AP) treatment, especially with second-generation APs, is strongly linked to weight gain, which increases patients\u2019 risk of developing obesity and other metabolic diseases. There is an important genetic risk component that can contribute to the appearance of these disturbances. The aim of the present study was to evaluate the effect of polymorphisms in selected candidate genes on obesity and other anthropometric and metabolic traits in 320 AP-treated FEP patients over the course of a 2-year follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>These patients were recruited in the multicentre PEPs study (Phenotype\u2212genotype and environmental interaction; Application of a predictive model in first psychotic episodes).
