Hausler N, et al. - By analyzing two community-based cohorts, the Paris Prospective Study 3 (PPS3, France, n=6,441) and the CoLaus study (Switzerland, n=2,989), researchers examined the link between cardiovascular health (CVH), as defined by the American Heart Association and a number of sleep disturbances. Seven metrics included in CVH could be categorized as poor, intermediate and ideal, and they classified global CVH score into poor (0–2 ideal metrics), intermediate (3–4 ideal metrics) and ideal (≥5 ideal metrics) as well. They determined links between global CVH and self-reported sleep disturbances (proxy of sleep-disordered breathing [SDB], excessive daytime sleepiness, insomnia symptoms and short/long sleep duration) and SDB severity by polysomnography (PSG). Cases with previous cardiovascular disease were excluded. Lower odds of SDB and excessive daytime sleepiness were observed in relation to higher levels of CVH. However, links seemed to be bidirectional and causal interpretation could not be made.
