ABSTRACT=Objective
This study analyzed the association of high blood pressure (HBP) with physical activity, sedentary behavior, and sedentary breaks in 2-year follow-up. 
Methods
A sample of 331 middle-aged and older adults (mean age of 59.6±17.3 years) was randomly selected and assessed at baseline and after 2 years of follow-up.  HBP was considered as >140/90 mmHg values of systolic and diastolic blood pressure. Physical activity, sedentary behavior, and sedentary breaks were assessed by questionnaire. Age, sex, socioeconomic status, and body mass index were covariates. 
Results
Continuous HBP was observed in 26.3% of sample between baseline and follow-up. Adults who reported continuously high sedentary breaks at leisure activities were less likely to have HBP (OR=0.34, p=0.011), as well as those who remained high physically active (OR=0.41, p=0.016), even after mutual adjustment. No association was observed between high sedentary behavior and HBP at follow-up. 
Conclusion
Community dwelling adults who were high active and performed frequent sedentary breaks were less likely to have HBP in 2-year follow-up. Strategies for HBP control should considered both physical activities and leisure sedentary breaks in adult population.
