In the pairwise correlation and clustering analysis, the food intake cluster (energy intake, sugar intake, and food weight) was positively associated with oxytocin-specific polygenic scores, and the body fat cluster (body mass index, trunk fat, and total body fat) pointed to a positive association with the polygenic scores of oxytocin, diabetes, and schizophrenia [326]. This evidence concerns the gene OXT and schizophrenia.
