Background: Second-generation antipsychotics (SGA) are associated with weight gain. SGA can increase appetite, but few research examined the correlates of psychological eating behaviours in early psychosis individuals (EPI). Objective: To analyze the correlates of psychological eating behaviours with anthropometric, metabolic, psychiatric/functional outcomes in EPI. Methods: 29 EPI (18 men; mean age: 25.67 ± 2.95; mean BMI: 31.50 ± 6.91 kg/m²) referred to a physical activity program were included. They completed the three-factor eating questionnaire assessing cognitive dietary restraint (CR), uncontrolled eating (UE) and feeling of hunger (FH). Body composition was evaluated with an anthropometric scale. Metabolic outcomes were measured with blood samples. Psychiatric/functional outcomes were assessed by interview with a research assistant. Results: Flexible CR was correlated to lifetime highest weight reached (r = 0.54, p = 0.004), but also to waist circumference (r = 0.52, p = 0.002), BMI (r = 0.47, p = 0.01), and systolic (r = 0.48, p = 0.01). UE was highly correlated with FH (r = 0.62, p <0.001) and both, UE (r = 0.52, p = 0.004) and FH (r = 0.58, p = 0.001) were related to higher number of meals and snacks per day. Flexible CR and was associated with social functioning (SOFAS; r = 0.43, p = 0.02). No other association was found with psychiatric/functional outcomes. Rigid CR was negatively associated to fasting glucose (r = -0.40, p = 0.03). No differences between females and males. Conclusion: Psychological eating behaviour may have a role in weight gain associated with SGA.
