Background: The relationship between long-term changes in BMI and blood pressure (BP) and associated comorbidities remain to be clarified.
Objectives and Methods: A total of 476 office workers who had received routine medical checks in both 2010 and 2019 were enrolled as a retrospective cohort. Changes in BMI and BP were analyzed in relation to age, sex, antihypertensive treatment, and body shape.
Results: Weak but significant positive correlations were found between decade-long changes in BMI and BP. The correlation coefficients tended to be higher in males and obese persons in their 50–60s. In patients under antihypertensive treatment, a decline in BMI resulted in better control of BP. Meanwhile, in normotensive people, an increase in BMI resulted in a significant elevation in BP. A more than 10% decline in BMI in obese individuals resulted in a significant decrease in BP, whereas a greater than 10% increase in BMI in normal shape people resulted in a significant increase in BP.
Conclusion: Long-term control of BMI within the normal range is essential for good control of BP and a reduction in cardiovascular risk.
