Association between higher blood pressure level in children and adult blood pressure: 17 years follow-up results / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>Essential hypertension may begin at childhood. The aim of this study is to identify the risk factors of hypertension and detect the evolvement tracking of blood pressure in childhood.</p><p><b>METHODS</b>In this study, we followed up blood pressure changes in 4623 school children (6 - 15 years-old) from 1987 to 2005 in Hanzhong rural area. A total of 152 children were grouped to higher blood pressure group [systolic blood pressure (P(SBP)) >or= 75(th) (P(75))] and 140 children grouped to normal blood pressure group [P(SBP) < 50(th) (P(50))] and their blood pressure were re-measure 18-years later.</p><p><b>RESULTS</b>The total follow-up rate was 70.2%. Follow-up blood pressure was significantly higher in higher blood pressure group at baseline than that in normal blood pressure group at baseline (P < 0.05). The hypertension rate at follow up was significantly higher in higher blood pressure group at baseline than that in normal blood pressure group at baseline (28.0% vs. 4.1%, P < 0.01). The risk for hypertension was 6.88 greater in higher blood pressure group at baseline than that in normal blood pressure group at baseline.</p><p><b>CONCLUSIONS</b>Higher blood pressure at childhood is a risk of developing hypertension at adulthood.</p>
