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 11/2 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.", pages = "545-560", url = "http://www.ingentaconnect.com/content/png/ajhb/2007/00000031/00000005/art00010", doi = "doi:10.5993/AJHB.31.5.10", keyword = "blood pressure, nutrition, physical activity, fitness, lifestyle" }
