Social jet lag was calculated as the difference between sleep timing on workdays and non-workdays. Statistical analyses included the Shapiro-Wilk test, Student's <i>t</i>-test, Mann-Whitney <i>U</i> test, chi-square test, and binary logistic regression. Group comparisons between four categories (fathers and childless men, with and without social jet lag) were performed using the Kruskal-Wallis test. The study sample consisted of 238 adult men (mean age = 28 years; SD = 9.05).
