The advent of web-based advertisements through media platforms such as Facebook offers a new method of reaching target audiences who can be both cost-effective and specific. A Facebook advertisement was displayed for 48 hours and consisted of a 26-character Chinese text body. The advertisement linked to an external informational video on hypertension prevention. Demographic information including age and gender were recorded. Descriptive statistics were used to compare reach and number of ad clicks between age groups. The 48-hour campaign reached a total of 508 people. Of those reached, 289 participants (56.9%) were between the ages of 55–64 years, and 170 participants (33.5%) were 65 years or older.

Aldosterone promotes vascular calcification and stiffness, but the relationships between aldosterone, MGP, and arterial stiffness are unknown. We studied 199 adults (predominantly older men) with hypertension. We assessed the relationship between levels of dephospho-uncarboxylated MGP (dp-ucMGP), aldosterone, and carotid-femoral pulse wave velocity (CF-PWV) using standard regression and mediation analyses. Plasma aldosterone was measured in a subgroup of subjects (n = 106). Aldosterone was strongly associated with dp-ucMGP (standardized β = 0.50, <em>P</em> &lt; .001), which was independent of potential confounders (β = 0.37, <em>P</em> &lt; .001).

Plasma aldosterone was also significantly associated with CF-PWV (standardized β = 0.21; <em>P</em> = .035). However, in a model that included aldosterone and dp-ucMGP, only the latter was associated with CF-PWV. Mediation analyses demonstrated a significant dp-ucMGP–mediated effect of aldosterone on CF-PWV, without a significant direct (dp-ucMGP independent) effect. Our study demonstrates a novel independent association between high aldosterone levels and dp-ucMGP, suggesting that aldosterone may influence the MGP pathway. This relationship appears to underlie the previously documented relationship between aldosterone and increased arterial stiffness.</p></div>","PeriodicalId":17220,"journal":{"name":"Journal of The American Society of Hypertension","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jash.2018.06.018","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36334009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
