Tracking of Blood Pressure over a 40-Year Period in the University of Manitoba Follow-up Study, 1948–1988
Key result
Blood pressure tracking was significant over 5 to 35-year intervals in men aged 25-75 years, with the strongest evidence for tracking observed in middle age (45-55 years).

Implication
May identify high-BP men for early monitoring; extends tracking data but remains hypothesis-generating without intervention trials.
Key Points
- The aim is to examine the tracking of blood pressure measurements over a 40-year period to identify risk factors for hypertension.
- Cohort of 3,983 men followed from 1948 to 1988.
- Used correlation analysis and likelihood quantification for tracking blood pressure.
- Measurements analyzed for ages 25-75 years with intervals from 5 to 35 years.
- Significant evidence for blood pressure tracking found, especially between ages 45-55 years.
- Strength of tracking decreased as time between measurements increased.
- Men in the highest blood pressure quintile were identifiable at a younger age, highlighting prevention opportunities.

Outcome
Tracking of blood pressure over time (correlation analysis and likelihood of remaining in top or bottom quintile)surrogate
Blood pressure tracks significantly over time in men, suggesting that those at highest risk for hypertension can be identified in early adulthood for targeted prevention.
Cite This Study
Tate et al. (1995) conducted a cohort in High blood pressure (n=3,983). Blood pressure was evaluated on Tracking of blood pressure over time. Blood pressure tracking was significant over 5 to 35-year intervals in men aged 25-75 years, with the strongest evidence for tracking observed in middle age (45-55 years).
