The Sleep Health Foundation national sleep survey, 2010

A national landline telephone survey was undertaken of adolescents and adults (14 to > 70 years of age) across successive weekend evenings. The survey contained 14 questions about sleep: five about sleeping difficulty, two about snoring and OSA, one about restless legs, one about sleeping medication, three about daytime impairments usually associated with sleep disturbance, and two about nocturnal sleep duration. There were 1512 respondents from all states and territories, both urban and rural, with sampling proportionate to the populations of those areas, sex and age. Hillman DR, Lack LC.
