EPIDEMIOLOGICAL EVIDENCE FOR THE LINKS BETWEEN SLEEP DURATION AND HIGH BLOOD PRESSURE: A SYSTEMATIC REVIEW AND META-ANALYSIS

ABSTRACT Objective: To review the epidemiological evidence of the association between sleep duration and blood pressure in adolescents. Data sources: We performed a systematic review of observational studies in Medline, Scopus, Lilacs, Web of Science, Science Direct databases and Virtual Libraries in English, Spanish and Portuguese published until September 2018. Studies were selected first by title and abstract, then by complete reading, according to the eligibility criteria. The reference list of selected articles was evaluated in order to retrieve relevant studies. Data synthesis: Initially, 1,455 articles were retrieved. After exclusion due to duplicity or not meeting the eligibility criteria, 13 articles were included in the review. Studies varied greatly in sample size (143 to 6,940 patients), methods of measuring blood pressure and sleep duration, cutoff points, categorization and adjustment of variables. The main evidence from the studies is that short sleep duration is associated with high blood pressure in adolescence, although the presence of association between high blood pressure and long sleep duration is possible, but not clear in the literature. Conclusions: Sleep duration, especially short duration, is associated with high blood pressure in adolescents. Such evidence draws attention to implications on cardiovascular health in this age group.

AbstractHigh blood pressure is a risk factor for atherosclerosis in adults, but whether the same is true in children and young people is not known. This is important to guide management of high blood pressure in children and young people. We aimed to investigate the association in children and young people between blood pressure and carotid intima-media thickness, a non-invasive marker of atherosclerosis, through a systematic review. Studies were retrieved from MEDLINE and EMBASE. Articles were eligible for inclusion if they included at least one measurement of blood pressure and at least one measurement of ultrasound-derived carotid intima-media thickness, both measured during childhood (0–19 years), and a measure of effect size or correlation between the two measurements. A total of 3748 studies were identified in the initial search, of which 28 studies were included in this review. The results were mixed, but the largest and highest-quality studies suggested an independent positive association between blood pressure and carotid intima-media thickness in children and young people, even after adjustment for other cardiovascular risk factors. There was no indication of a clear threshold level for the effect of blood pressure on carotid intima-media thickness, hence there are insufficient data to support a pharmacological treatment threshold for the treatment of high blood pressure in children and young people to prevent future cardiovascular disease. The studies included varied widely in terms of quality and design, and it was not possible to combine the data in a meta-analysis. There is likely to be an independent association between blood pressure and carotid intima-media thickness in childhood, but it is not clear at what point this should be treated.

Vasodilators are drugs that induce or start the widening of blood vessels and are commonly applied to treat disorders with irregularly high blood pressure, including hypertension, congestive heart failure, and angina. The present study aims to systematically review the studies on the vasodilation effects of medicinal herbs. The study was done according to the 06- Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines and registered in the CAMARADES-NC3Rs Preclinical Systematic Review and Meta-Analysis Facility (SyRF) database. Various English databases, such as Scopus, PubMed, Web of Science, EMBASE, and Google Scholar, were used to find publications about the vasodilation effects of medicinal herbs with no date limitation. The searched terms and keywords words were: "medicinal herbs", "medicinal plants", "vasodilator", "vasorelaxant", "hypertension", "high blood pressure", "vasodilation", "extract", "essential oil". Out of 1820 papers (up to 2020), 31 papers met the inclusion criteria and were reviewed. The most important medicinal plants with vasodilation/vasorelaxant activity belonged to the family Asteraceae (19.4%) followed by Zingiberaceae (9.7%). Aerial parts (30.5%), leaves (30.5%), followed by roots (11.1%) were the most common parts used in the studies. The findings showed that ethanolic extract (33.3%), followed by aqueous extract (22.2%) and methanolic extract (19.4%) was the frequency used extraction methods, whereas the essential oil (13.9%) and hydroalcoholic extract (8.3%) were the second most used herbal remedies. The results of the current review study revealed that the plant vasodilatory agents were might be used as an alternative and complementary source to treat hypertension as they had lower important toxicity. Nevertheless, more investigations, particularly clinical trials, are needed to clear this suggestion.
