Relationship between sleep and cardiovascular health score to define phenogroups. Sleep duration was defined as adequate (≥ 7 to < 9 h) or non-adequate (< 7 and ≥ 9 h). Cardiovascular health was defined as ideal (Life’s Simple 7 Health Score: > 7), intermediate (Life’s Simple 7 Health Score: > 5 to ≤ 7), or poor (≤ 5). The relationship between sleep and cardiovascular health score revealed three phenogroups: resilient, defined by ideal cardiovascular health and non-adequate sleep (n = 83); uncoupled, defined by intermediate or poor cardiovascular health, but adequate sleep (n = 53); and concordant where sleep duration and cardiovascular health measures were aligned with adequate sleep and ideal cardiovascular health or non-adequate sleep and intermediate or poor cardiovascular health (n = 171)
