Effect of visit-to-visit blood pressure variability on cardiovascular events in populations with different body mass indexes: a prospective cohort study.

ABSTRACT:

Objective

This study was performed to explore the effects of visit-to-visit blood pressure variability (BPV) on cardiovascular events (CVEs) in people with various body mass indexes (BMIs).

Design

Prospective cohort study.

Setting

The average real variability of systolic blood pressure (ARV_SBP) was the indicator for visit-to-visit BPV. The participants were divided into three groups: normal weight, overweight and obesity. We further divided these groups into four subgroups based on the ARV_SBP. A Cox regression model was used to calculate the HRs of the ARV_SBP on CVEs in the same and different BMI groups. Additionally, a competitive risk model was used to calculate the HRs of the ARV_SBP on CVEs in the same BMI group.
