INTRODUCTIONSerum 25-hydroxyvitamin D (25OHD) deficiency (<50 nmol/l or 20ng/ml) has been associated with increased blood pressure (BP) in observational studies. A paucity of data on this relationship is available in Latin American or child populations. This study investigates the association between 25OHD levels and BP in adolescents at risk for vitamin D deficiency in 2 Peruvian settings.METHODSIn a population-based study of 1,441 Peruvian adolescents aged 13–15 years, 1,074 (75%) provided a serum blood sample for 25OHD analysis and BP measurements. Relationships between 25OHD and BP metrics were assessed using multiple linear regressions, adjusted for anthropometrics and sociodemographic factors.RESULTS25OHD deficiency was associated with an elevated diastolic BP (DBP) (1.09mm Hg increase, 95% confidence interval: 0.04 to 2.14;P= 0.04) compared to nondeficient adolescents. Systolic BP (SBP) trended to increase with vitamin D deficiency (1.30mm Hg increase, 95% confidence interval: −0.13 to 2.72;P= 0.08). Mean arterial pressure (MAP) was also greater in adolescents with 25OHD (1.16mm Hg increase, 95% confidence interval: 0.10 to 2.22;P= 0.03). SBP was found to demonstrate a U-shaped relationship with 25OHD, while DBP and MAP demonstrated inverse J-shaped relationships with serum 25OHD status. The association between 25OHD deficiency and BP was not different across study sites (allP≥ 0.19).DISCUSSIONAdolescents deficient in 25OHD demonstrated increased DBP and MAP and a trend toward increased SBP, when compared to nondeficient subjects. 25OHD deficiency early in life was associated with elevated BP metrics, which may predispose risk of hypertension later in adulthood.
