A Mexican sample of 86 adolescents with schizophrenia was examined during a 6-month follow-up using the Simpson–Angus, abnormal involuntary movement and Barnes Akathisia rating scales, in addition to a side effects score sheet and other laboratory measures. Binary logistic regression models were used to identify specific variables as predictors of weight gain. Sleep difficulties, restlessness, drowsiness, changes in thyroid hormones, and a linear increase in weight gain were observed. A baseline positive and negative syndrome scale score greater than 97 predicted a 5 kg increase at month 3 (odds ratio: 4.52, 95% confidence interval: 1.5–13.2). The absence of a plateau in weight gain in the present study across the 6-month treatment period and its relationship with illness severity suggests that even longer follow-up time should be examined in future studies in these patient populations.
