Abstract
Purpose: To examine existing literature on the effectiveness of increased physical activity versus dietary salt restriction in blood pressure control of overweight adults.
Background: Almost 50% of adults in the United States have hypertension, a major risk factor for cardiovascular disease. Current clinical guidelines recommend lifestyle modifications such as reduced salt intake and increased physical activity to manage hypertension in overweight adults
and purport that each lifestyle change can decrease blood pressure. Single lifestyle modifications have not been adequately explored in overweight adults.
PICOT Question: In patients who are overweight, does participating in aerobic exercises help reduce hypertension as compared to limiting salt intake for 2 months or more?
Methods: This integrative literature review used electronic databases, CINAHL and Google Scholar, to search for publications between 2010 and 2023.
Results: Fifteen studies were identified that met the inclusion criteria. The results revealed that a combination of aerobic exercise and reduced salt intake decreased blood pressure in overweight adults.
Conclusion: Current evidence on the effects of either salt restriction or physical activity alone in blood pressure control for overweight adults is not certain. Further research is needed to ascertain the effectiveness of a single lifestyle modification for blood pressure control in this population.
Keywords: Hypertension, Low-Salt Diet, Aerobic Exercise, Overweight Adults
