These researchers obtained data from Wave 7 (conducted in 2014) of the Australian national Longitudinal Study of Indigenous Children survey for this investigation into whether poor sleep quality might contribute to health outcomes in Aboriginal children. The analysis specifically sought to determine whether an association exists between sleep duration and BMI. Short sleep was defined as <9 h for school-age children. Wave 7 of this survey included 1,253 children aged 7–12 years. Interviewers asked primary carers about children’s sleep times. Regardless of age, relative socioeconomic disadvantage and level of remoteness, unhealthy weight (underweight, overweight, or obese) was associated with less sleep duration than healthy weight for Indigenous children.
