Abstract Objective Using bipolar disorder (BD) as a control, we explored the possible developmental process of impaired glucose metabolism rhythm. Methods In total, 441 subjects (77, 162, 134, 54, and 14 in the pre-diabetes [pre-DM], DM, BD, BD + pre-DM, and BD + DM groups, respectively) and 160 controls were included. All subjects were assessed using the Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI). The hypothalamic-pituitary-adrenal (HPA) and hypothalamic–pituitary–thyroid (HPT) axes were measured. Results Cluster analysis showed that the BD, BD + DM, and DM groups were classified as the ‘disease group, the BD + pre-DM group as the ‘mixed period group’, and the pre-DM group as the ‘pre-disease group’. The conscientiousness factor scores of the NEO-FFI in the ‘disease group’ were higher than the norm but lower than the norm in the ‘pre-disease group’. The scores of neurotic factors in the ‘pre-disease’ and ‘mixed period’ groups were both significantly higher than that in the ‘disease group’ (corrected p < 0.001). The incidences of the abnormal HPA axis decreased gradually from the ‘pre-disease group’ to the ‘mixed period group’ then to the ‘disease group’, while those of the HPT axis slightly increased at first and then significantly decreased. The overall prediction rate of the multiple logistic regression model was 92.7%. Conclusion This study suggests that progression of pre-diabetes to DM is a continuous process from local abnormalities to rhythm disorder of glucose metabolism. This understanding can be applied to the whole course management and early intervention of DM and to the future development of optimised treatment based on rhythm regulation.
