Lifestyle behavior changes including reduced sodium, improved fitness, and DASH diet adherence predicted SBP reductions of 0.5 to 1.5 mm Hg, but were difficult to detect when adjusting for weight.

Do individual lifestyle changes reduce systolic blood pressure in PREMIER trial participants?
Individual lifestyle changes such as reduced sodium, improved fitness, and DASH diet adherence contribute to blood pressure lowering, though their independent effects are difficult to isolate when weight loss is included in the model.
OBJECTIVES: To assess contributions of individual lifestyle changes on systolic blood pressure (SBP) changes. METHODS: We examined associations between lifestyle behavior changes and SBP after 6 and 18 months in 782 PREMIER trial participants. RESULTS: In multivariate models omitting weight, predicted SBP reductions ranged from (1)/2 to 1(1)/2 mm Hg for reduced urinary sodium, improved fitness, and adherence to the DASH diet (except sodium at 18 months). With weight included, only fitness change additionally predicted SBP at 18 months. CONCLUSIONS: Several lifestyle behavior changes are important for BP lowering, but are difficult to detect when weight is included in multivariate models.
Obarzanek et al. (Sat,) conducted a cohort in Blood pressure (n=782). Lifestyle behavior changes was evaluated on Systolic blood pressure (SBP) changes. Lifestyle behavior changes including reduced sodium, improved fitness, and DASH diet adherence predicted SBP reductions of 0.5 to 1.5 mm Hg, but were difficult to detect when adjusting for weight.
