Abstract Objectives The aims were to explore multidimensional sleep health and the different dimensions of sleep health in the adult Norwegian population in relation to sex, age, education, circadian preference, and chronic insomnia. Methods A representative sample of 1028 Norwegians, aged 18 + years completed a cross-sectional web-based survey. Sleep health was measured with the multidimensional RUSATED scale, which assesses the dimensions of regularity, satisfaction, alertness, timing, efficiency, and duration. Insomnia was assessed with the Bergen Insomnia Scale. Data were analyzed with chi-square tests, t-tests, one-way ANOVAs, and regression analyses, as appropriate. Response rate was 33. 5%. Results Sleep health was better in males, with increasing age, and with higher educational level, and was poorer in participants with evening preference and chronic insomnia, compared to their respective counterparts. When investigating the different sleep health dimensions, males scored better than females on satisfaction (adjusted odds ratio aOR = 0. 69, 95% CI = 0. 51 to 0. 93), timing (aOR = 0. 66, 95% CI = 0. 49 to 0. 88), and efficiency (aOR = 0. 68, 95% CI = 0. 52 to 0. 89). Older age was associated with better scores on regularity and satisfaction, whereas young age was associated with better scores on alertness and duration. High educational level was associated with better scores on alertness, timing, and duration. Evening types scored worse than morning types on regularity (aOR = 0. 27, 95% CI = 0. 18 to 0. 41), satisfaction (aOR = 0. 37, 95% CI = 0. 26 to 0. 53), and timing (aOR = 0. 36, 95% CI = 0. 26 to 0. 51). Participants with chronic insomnia scored worse than participants without insomnia on all six sleep health dimensions. Conclusions Sleep health differed significantly in relation to sex, age, education, circadian preference, and chronic insomnia. However, specific group differences were not equally evident in all sleep health dimensions.
