“…We divided the sample into three chronotype categories based on individual variation of MSF sc : early, intermediate, and late. Tertile splits were applied to the whole sample to generate these categories, as used in the literature [49, 50], but we acknowledge that there are also other ways of categorising chronotype that are based on quartiles and percentiles, respectively [51, 52]. Information on sleep duration was gathered from the MCTQ.…”

Introduction: Chronotype describes a person’s preferential activity pattern during a 24-hour period, which may not be in line with their social lifestyle. A mismatch between biological and social time is known as “social jetlag,” which has negative effects on wellbeing. Cocaine influences a person’s activity levels, but very little is known about possible changes in chronotype of patients with cocaine use disorder (CUD). Here, we aimed to shed light on self-reported changes in chronotype in patients with CUD and the clinical implications. Methods: A total of 90 men from the local community were recruited; about half of the sample met the criteria for CUD, while the other half were healthy without a personal history of substance use disorder. Participants completed the Munich Chronotype Questionnaire along with questionnaires about mental health, daily fatigue, and drug/alcohol use. Results: Half of the CUD patients fell into the category of late chronotype – a significantly larger proportion than their healthy peers. Late “night owls” tended to have started using cocaine at an earlier age than other chronotypes; a finding that was not observed with tobacco, cannabis, or alcohol. Drug use severity in CUD patients did not differ across chronotypes. CUD patients (52%) did not have a preferred time of day to use cocaine. The mismatch between social and biological time was significantly greater in CUD patients and unrelated to drug use or mental health status. Conclusion: CUD appears to be associated with disruptions in chronotype which are, contrary to a widely held view, not reflected by using patterns or addiction severity.

Background This study aimed to investigate the relationship between chronotypes and aggression in adolescents. Methods A cross-sectional study was conducted on 755 primary and secondary school students aged 11–16 years in rural areas of Ningxia Province, China. The Chinese version of the Buss-Perry Aggression Questionnaire (AQ-CV) and the Chinese version Morningness-Eveningness Questionnaire (MEQ-CV) were used to assess the aggressive behavior and chronotypes of the study subjects. The Kruskal-Wallis test was then used to compare the differences in aggression among adolescents with different chronotypes, and Spearman correlation analysis to determine the relationship between chronotypes and aggression. Further linear regression analysis was used to investigate the effects of chronotype, personality traits, family environment, and class environment on adolescent aggression. Results There were significant differences in chronotypes between different age groups and different sexes. Spearman correlation analysis showed that the MEQ-CV total score was negatively correlated with the AQ-CV total score (r = -0.263) and score of each AQ-CV subscale. In Model 1, chronotypes were negatively associated with aggression when controlling for age and sex, and evening-type adolescents might be more likely to exhibit aggressive behavior (b = -0.513, 95% CI: [-0.712, -0.315], P < 0.001); in Model 2, the negative association remained after controlling for family and class environment on the basis of Model 1 (b = -0.404, 95% CI: [-0.601, -0.208], P < 0.001); and in Model 3, the negative association still existed after controlling for personality traits on the basis of Model 2 (b = -0.383, 95% CI: [-0.577, -0.190], P < 0.001). Conclusion Compared to morning-type adolescents, evening-type adolescents were more likely to exhibit aggressive behavior. Given social expectations for MT adolescents, adolescents should be actively guided to develop a good circadian rhythm that may be more conducive to their physical and mental development.
