title: Obesity is associated with visit-to-visit systolic blood pressure variability in the US adults.
abstract: BACKGROUND
  Evidence has accumulated showing that blood pressure variability is associated with cardiovascular disease. A substantial increase in the prevalence of obesity has been documented globally. Our objective was to examine the relation of total and central obesity on visit-to-visit blood pressure variability.
  
  
  METHODS
  We used data collected from the cross-sectional Third National Health and Nutrition Examination Survey, to examine the association of visit-to-visit blood pressure variability with body mass index and waist circumference.
  
  
  RESULTS
  The analysis included 14,988 participants. The participants' mean age was 43.45 years. Visit-to-visit systolic blood pressure variability was associated with a body mass index ≥30 and a large waist circumference (beta coefficients were 0.25 and 0.31, respectively, P-values < 0.01). Neither the bivariate nor the multivariable analyses showed significant relationships between the obesity indicators and diastolic blood pressure variability.
  
  
  CONCLUSIONS
  Obesity is associated with visit-to-visit systolic blood pressure variability. Additional research is required to replicate the reported results in prospective studies and evaluate approaches to reduce blood pressure variability observed in clinical settings among obese persons to reduce its subsequent complications.
