    Family PArtners in Lifestyle Support (PALS): Family-based weight loss for African American adults with type 2 diabetes.
    (Obesity (Silver Spring), 2017-01) Samuel-Hodge, Carmen D; Holder-Cooper, Judith C; Gizlice, Ziya; Davis, Gwendolyn; Steele, Sonia P; Keyserling, Thomas C; Kumanyika, Shiriki K; Brantley, Phillip J; Svetkey, Laura P
    OBJECTIVE: To develop and test a family-centered behavioral weight loss intervention for African American adults with type 2 diabetes. METHODS: In this randomized trial, dyads consisting of an African American adult with overweight or obesity and type 2 diabetes (index participant) paired with a family partner with overweight or obesity but not diagnosed with diabetes were assigned in a 2:1 ratio to a 20-week special intervention (SI) or delayed intervention (DI) control group. The primary outcome was weight loss among index participants at the 20-week follow-up. RESULTS: One hundred eight participants (54 dyads-36 (SI) and 18 (DI) dyads) were enrolled: 81% females; mean age, 51 years; mean weight,103 kg; and mean BMI, 37 kg/m(2) . At post-intervention, 96 participants (89%) returned for follow-up measures. Among index participants, mean difference in weight loss between groups was -5.0 kg, P <0.0001 (-3.6 kg loss among SI; 1.4 kg gain in DI). SI index participants showed significantly greater improvements in hemoglobin A1c, depressive symptoms, family interactions, and dietary, physical activity, and diabetes self-care behaviors. SI family partners also had significant weight loss (-3.9 kg (SI) vs. -1.0 kg (DI), P = 0.02). CONCLUSIONS: A family-centered, behavioral weight loss intervention led to clinically significant short-term weight loss among family dyads.

    Impact of 5-year weight change on blood pressure: Results from the weight loss maintenance trial
    (Journal of Clinical Hypertension, 2013) Tyson, Crystal C; Appel, Lawrence J; Vollmer, William M; Jerome, Gerald J; Brantley, Phillip J; Hollis, Jack F; Stevens, Victor J; Ard, Jamy D; Patel, Uptal D; Svetkey, Laura P
    In this secondary analysis of the Weight Loss Maintenance trial, the authors assessed the relationship between blood pressure (BP) change and weight change in overweight and obese adults with hypertension and/or dyslipidemia who were randomized to 1 of 3 weight loss maintenance strategies for 5 years. The participants were grouped (N=741) based on weight change from randomization to 60 months as: (1) weight loss, (2) weight stable, or (3) weight gain. A significant positive correlation between weight change and systolic BP (SBP) change at 12, 30, and 60 months and between weight change and diastolic BP (DBP) change at 30 months was observed. From randomization to 60 months, mean SBP increased to a similar degree for the weight gain group (4.2±standard error=0.6 mm Hg; P<.001) and weight stable group (4.6±1.1 mm Hg; P<.001), but SBP did not rise in the weight loss group (1.0±1.7 mm Hg, P=53). DBP was unchanged for all groups at 60 months. Although aging may have contributed to rise in BP at 60 months, it does not appear to fully account for observed BP changes. These results suggest that continued modest weight loss may be sufficient for long-term BP lowering. © 2013 Wiley Periodicals, Inc.
