Key result
Upper levels of normal systolic blood pressure (110-119 mm Hg) increased the risk of developing hypertension compared to <110 mm Hg in women (HR 2.43; 95% CI 1.50-3.93) and men (HR 2.44).
Why the study?
Does high-normal blood pressure increase the risk of developing hypertension in a low-income Mexican population?
Cohort (n=1,572)
Does high-normal blood pressure increase the risk of developing hypertension in a low-income Mexican population?
Hazard Ratio: 2.43 (95% CI 1.5–3.93)
Even within the normal blood pressure range, higher baseline blood pressure levels are associated with a significantly increased risk of progression to hypertension.

Incidence rises across normal BP subcategories in this cohort; leaves open targeted prevention strategies in similar populations.
Jiménez-Corona et al. (2007) conducted a cohort in Prehypertension and Normal Blood Pressure (n=1,572). Upper levels of normal systolic blood pressure (110 to 119 mm Hg) vs. Systolic blood pressure <110 mm Hg was evaluated on Incidence of hypertension (SBP ≥140 mm Hg, DBP ≥90 mm Hg, or physician diagnosis with antihypertensive medications) (HR 2.43, 95% CI 1.50-3.93). Upper levels of normal systolic blood pressure (110-119 mm Hg) increased the risk of developing hypertension compared to <110 mm Hg in women (HR 2.43; 95% CI 1.50-3.93) and men (HR 2.44).
