Preventing Weight Gain One-Year Results of a Randomized Lifestyle Intervention: one-year results of a randomized lifestyle intervention

Background: Lifestyle interventions targeting prevention of weight gain may have better long-term success than when aimed at weight loss. Limited evidence exists about such an approach in the primary care setting. Design: An RCT was conducted. Setting/Participants were 457 overweight or obese patients (BMI=25-40 kg/m(2), mean age 56 participants: years, 52% women) with either hypertension or dyslipidemia, or both, from 11 general practice locations in the Netherlands. Intervention: In the intervention group, four individual visits to a nurse practitioner (NP) and one feedback session by telephone were scheduled for lifestyle counseling with guidance of the NP using a standardized computerized software program. The control group received usual care from their general practitioner (GP). Main outcome measures: Changes in body weight, waist circumference, blood pressure, and blood lipids after 1 year (dropout Results: There were more weight losers and stabilizers in the NP group than in the general practitioner usual care (GP-UC) group (77% vs 65%; p Conclusions: Standardized computer-guided counseling by NPs may be an effective strategy to support weight-gain prevention and weight loss in primary care, in the current trial, particularly among men.
