“…PISA was an observational prospective trial assessing clinical and molecular factors responsible for BP changes associated with obstructive sleep apnea. The authors found that the 24‐hour mean systolic BP was 12.7 mm Hg higher in LIMBS and 4.7 mm Hg higher in PISA study among participants with short sleep duration, defined as less than seven hours of sleep per night, in comparison with those with longer sleep, independently of nocturnal and in‐office BP . These findings confirm and build up the existing body of knowledge whereby daily sleep duration affects health outcomes.…”

“…Unfortunately, lines of evidence pointed to the adverse effect of low‐quality sleep on blood pressure, and this association appears stronger in middle‐aged adults and in women 22 . For example, the 24‐h mean systolic blood pressure was 12.7 mmHg higher among participants with shorter sleep duration (less than 7 h) compared to those with longer sleep duration (at least 7 h) 23 . Nevertheless, all the studies mentioned above did not focus on pregnant women.…”

Aim: Previous studies indicated that excessive screen time was associated with hypertension in children and adolescents. In our hospital, pregnant women tended to spend a lot of time on electronic devices like smartphones. We aimed to explore the relationship between the screen time and hypertensive disorders of pregnancy (HDP). Methods: A case-control study was conducted from November 2019 to May 2020. A total of 160 women with HDP and 197 healthy controls who gave birth to children in the same hospital were recruited and information was recorded by questionnaires. Multivariate analysis was conducted to assess the effect of screen time on HDP. Results: The results showed that, exposure to electronic screen before nocturnal sleep in cases was significantly longer than that in controls (P = 0.011, odds ratio = 1.50). Smartphones (and/or tablet computers) used only for entertainment also significantly increased the susceptibility to HDP (P < 0.001, odds ratio = 2.84). Other related factors were following: work experience during pregnancy (P = 0.034, odds ratio = 0.53), history of diabetes mellitus (P = 0.013, odds ratio = 2.55), history of family hypertension (P < 0.001, odds ratio = 3.81), body mass index of pre-pregnancy (>25 kg/m 2) (P < 0.001, odds ratio = 6.16). Conclusion: In conclusion, long exposure to electronic screen before nocturnal sleep and the smartphones usage for only entertainment may be associated with the susceptibility to HDP.

“…Along this line, sleep quality seems to play an important role in BP control 6 with short sleep duration or poor sleep efficacy being associated with hypertension developing 7 . Sleep deprivation increases BP by changing cardiovascular autonomic modulation, mainly impairing baroreflex control and increasing cardiac sympathovagal balance 8 .…”

Hypertensives present cardiac autonomic dysfunction. Reduction in sleep quality increases blood pressure (BP) and favors hypertension development. Previous studies suggested a relationship between cardiovascular autonomic dysfunction and sleep quality, but it is unclear whether this association is present in hypertensives. Thus, this study evaluated the relationship between sleep quality and cardiac autonomic modulation in hypertensives. Forty‐seven middle‐aged hypertensive men under consistent anti‐hypertensive treatment were assessed for sleep quality by the Pittsburgh Sleep Quality Index (PSQI—higher score means worse sleep quality). Additionally, their beat‐by‐beat BP and heart rate (HR) were recorded, and cardiac autonomic modulation was assessed by their variabilities. Mann‐Whitney and t tests were used to compare different sleep quality groups: poor (PSQI > 5, n = 24) vs good (PSQI ≤ 5, n = 23), and Spearman’s correlations to investigate associations between sleep quality and autonomic markers. Patients with poor sleep quality presented lower cardiac parasympathetic modulation (HR high‐frequency band = 26 ± 13 vs 36 ± 15 nu, P = .03; HR total variance = 951 ± 1373 vs 1608 ± 2272 ms2, P = .05) and cardiac baroreflex sensitivity (4.5 ± 2.3 vs 7.1 ± 3.7 ms/mm Hg, P = .01). Additionally, sleep quality score presented significant positive correlation with HR (r = +0.34, P = .02) and negative correlations with HR high‐frequency band (r = −0.34, P = .03), HR total variance (r = −0.35, P = .02), and cardiac baroreflex sensitivity (r = −0.42, P = .01), showing that poor sleep quality is associated with higher HR and lower cardiac parasympathetic modulation and baroreflex sensitivity. In conclusion, in treated hypertensive men, poor sleep quality is associated with cardiac autonomic dysfunction.
