BMI, body mass index; M ± SD, mean and standard deviation; n, number of participants; %, percentage of sample. Poverty operationalized as ≤$20 000 in annual income. Sleep latency, sleep onset insomnia, sleep maintenance insomnia, and sleep duration were derived from the Pittsburgh Sleep Quality Index. Suicidal ideation assessed by EPDS item #10 such that any endorsement is a positive screen.
