Abstract

BACKGROUND: There is a paucity of data describing the sustained benefits of lifestyle interventions on health behaviors and blood pressure (BP). METHODS: We examined the persistence of changes in health habits and BP in the ENCORE study, a trial in which 144 overweight individuals with above-normal BP were randomized to one of the following 16-week interventions: Dietary Approaches to Stop Hypertension (DASH) diet alone (DASH-A), DASH diet plus a behavioral weight management intervention (DASH-WM), or Usual Care. Follow-up assessments were conducted 8 months after the end of treatment. RESULTS: At 16 weeks, systolic BP was reduced by 16.1 (95% confidence interval (CI) = 13.0-19.2) mm Hg in the DASH-WM group, 11.2 (95% CI = 8.1-14.3) mm Hg in the DASH-A group, and 3.4 (95% CI = 0.4-6.4) mm Hg in the Usual Care group. A decrease in BP persisted for 8 months, with systolic BP lower than baseline by 11.7 (95% CI = 8.1-15.3) mm Hg in the DASH-WM group, 9.5 (95% CI = 6.7-12.1) mm Hg in the DASH-A group, and 3.9 (95% CI = 0.5-7.3) mm Hg in the Usual Care group (P < 0.001 for active treatments vs. Usual Care). DASH-WM subjects lost 8.7 kg during the intervention and remained 6.3 kg lighter on follow-up examination. Changes in diet content were sustained in both DASH intervention groups. Among those who participated in DASH-WM, however, caloric intake was no longer lower, and only 21% reported still exercising regularly 8 months after completing the intervention. CONCLUSIONS: Changes in dietary habits, weight, and BP persisted for 8 months after completion of the 16-week ENCORE program, with some attenuation of the benefits. Additional research is needed to identify effective methods to promote long-term maintenance of the benefits of lifestyle modification programs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
