Social jetlag is associated with obesity-related disease indicators for inflammation and diabetes

Obesity-related disease indicators	Controlling for sex, chronotype and sleep duration		Controlling for smoking^a		Controlling for smoking and SES^b
	OR (95% CI)	P-value	OR (95% CI)	P-value	OR (95% CI)	P-value
High-sensitivity C-reactive protein levels (hsCRP)	1.3 (1.0–1.6)	0.046	1.2 (1.0–1.5)	0.102	1.2 (1.0–1.5)	0.092
Glycated hemoglobin	1.3 (1.0–1.6)	0.018	1.2 (1.0–1.6)	0.053	1.2 (1.0–1.5)	0.112

Abbreviations: CI, confidence interval; OR, odds ratio; SES, socioeconomic status. This table shows the OR, 95% confidence interval for the OR (95% CI) and P-value for social jetlag as a predictor in logistic regression models after excluding the healthy obese individuals (n = 100). The OR associated with social jetlag reflects the effect of a one-unit (s.d.) increase in social jetlag. Significant P-values (P < 0.05) are shown in bold.

Individuals who smoked were more likely to have high glycated hemoglobin levels (r = 0.11, P < 0.001), but not high hsCRP levels (r = 0.03, P = 0.33).

Lower SES status was related to high glycated hemoglobin levels (r = −0.10, P = 0.007), but not high hsCRP levels (r = −0.02, P = 0.58).
