Key result
Lower usual SBP by 20 mm Hg linked to ~35% lower vascular mortality in Mexican adults.
Why the study?
There is little direct evidence demonstrating the association between elevated blood pressure and cause-specific mortality in Hispanic populations, particularly in those with high prevalence of uncontrolled diabetes.
Population
133,613 Mexican adults aged 35 to 74 years without chronic disease besides diabetes
Comparison
Blood pressure levels and cause-specific mortality
Design
Prospective cohort study
Follow-up
Up to January 2018

Lower SBP was associated with reduced vascular mortality in Mexican adults; extends global evidence yet leaves causal effects and practice change open.

TAPIA-CONYER et al. (2020) conducted a cohort in General population with and without diabetes (n=133,613). Systolic blood pressure vs. Reference systolic blood pressure was evaluated on Vascular mortality between ages 35 to 74 years (RR 0.65, 95% CI 0.61-0.68). Each 20 mm Hg lower usual systolic blood pressure was associated with a 35% lower rate of vascular mortality (RR 0.65) among Mexican adults aged 35 to 74 years.
