Adjusted for school night sleep duration, demographic and household covariates, eating behaviours, but not ethnicity in Model 3e, linear regression analyses indicated that greater social jetlag (black line) was significantly associated with higher body mass index (BMI) percentile, b = .84, p = .037. After adjustment for ethnicity in Model 4, the association between social jetlag and BMI percentile was attenuated (grey line), b = .72, p = .072. *p < .05; n.s.—not significant.
