a. Simple slope plots for waist circumference by levels of average sleep efficiency (%) for high (+1SD) and low (−1SD) levels of SES. Simple slope associations between sleep efficiency and waist circumference were significant for children with low SES (b = −.13, p < .001) and average SES (b = −.06, p = .05). Region of significance analyses indicate that simple slopes were significant for families with SES scores less than .011 or about 57.4% of the sample. b. Simple slope plots for waist circumference by levels of parent-reported total sleep problem scores for high (+1SD) and low (−1SD) levels of SES. Simple slope associations between parent-reported sleep problems and waist circumference were significant for children with low SES (b = 1.38, p = .04). Region of significance analyses indicate that simple slopes were significant for families with SES less than −.64 or about 19.2% of the sample. *p ≤ .05; ** p ≤ .01; *** p ≤ .001.
