Blood pressure and lipid profiles in adolescents with hypertensive parents
problem of increasing prevalence and causes high morbidityand mortality. It is found primarily in young males, with afamilial history of hypertension and/or cardiovascular disease.Examination of lipid profiles has been used to detect the risk ofhypertension in adolescents.Objective To compare blood pressure and lipid profiles inadolescents with and without a parental history of hypertension.Methods This cross-sectional study was conducted from January toFebruary 2012 on students from a senior high school in the TobaSamosir District, North Sumatera. Sixty-eight adolescents wereincluded, aged 15 to 18 years. Group I comprised 34 adolescentswith hypertensive parents, and group II comprised 34 adolescentswith normotensive parents. Subjects were selected based onquestionnaires. Subjects’ blood pressures were measured at rest.Three measurements were made in intervals of 10-15 minutes,then averaged for both systolic and diastolic blood pressures. Lipidprofiles were measured using the CardioCheck cholesterol testafter subjects had fasted for 12 hours.Results The median systolic blood pressures (SBP) in groupsI and II were 110 mmHg (range 93.3-123.3) and 106.7 mmHg(range 96.7-123.3), respectively, (P=0.584). The median diastolicblood pressures (DBP) were 73.3 mmHg (range 66.7-83.3) and71.7 mmHg (range 63.3-80.0), respectively, (P=0.953). Totalcholesterol and low-density lipoprotein cholesterol (LDL-C) levelsin group I were significantly higher than those levels in group II[median total cholesterol: 162.0 (range 158-170) vs. 159.0 (range150-170), respectively; (P=0.001); and mean LDL-C: 103.5 (SD3.72) vs. 99.1 (SD 4.63), respectively; (P=0.001). Multivariateanalysis revealed a correlation of moderate strength betweenparental history of hypertension and increased LDL-C (P<0.001)in adolescents.Conclusion Adolescents with and without familial historyof hypertension have no significant median blood pressuredifferences. However, adolescents with hypertensive parents have afsignificantlyhigher median total cholesterol and mean LDL-C.Furthermore, we find a correlation between parental history ofhypertension and increased LDL-C in adolescents.
