[PMID: 35457744 PMCID: PMC9032860 DOI: 10.3390/ijerph19084877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/03/2022] [Revised: 04/08/2022] [Accepted: 04/13/2022] [Indexed: 11/16/2022]
Abstract
AIM To compare the efficacy of two popular weight loss approaches on weight loss, body composition, and markers of health in sedentary obese women. METHODS In total, 51 sedentary women (age 34.5 ± 7.7 yrs.; weight 90.0 ± 14.5 kg; BMI 34.0 ± 5.1 kg/m2; 46.5 ± 7.0% fat) were matched and randomized to participate in the Weight Watchers® Momentum™ (WW) or Curves® (CV) Fitness and Weight Management program for 16 weeks. Participants in the WW group (n = 27) were provided a point-based diet program, received weekly progress checks and counseling, and were encouraged to exercise. Participants in the CV group (n = 24) followed a menu-based higher protein/low-fat diet (1200 kcal/d) for 1 week; 1500 kcal/d diet for 3 weeks; and 2000-2500 kcals/d for 2 weeks that was repeated three times (except the last segment) while participating in a supervised circuit-style resistance training program (3 d/wk). A general linear model (GLM) with repeated measures was used to analyze data and are presented as mean changes from baseline (mean [UL, LL]). RESULTS Supervised CV training resulted in greater amounts of vigorous and total physical activity. After 16 weeks, both groups lost weight (WW -6.1 [-7.8, -4.6], CV -4.9 [-6.2, -3.2] kg, p = 0.264). Participants in the CV group observed greater reductions in fat mass (WW -2.9 [-6.7, -0.2], CV -6.4 [-9.2, -3.6] kg, p = 0.081) and increases in lean mass (WW -2.5 [-4.3, -0.7], CV 1.3 [-0.6, 3.2] kg, p = 0.005) resulting in more favorable changes in percent body fat (WW -1.4 [-4.1, 1.2], CV -4.7 [-7.5, -1.8]%, p = 0.098). Both groups observed improvements in peak aerobic capacity and muscular endurance, although bench press lifting volume was greater in the CV group. Those in the CV group experienced a greater increase in HDLc and reduction in the CHL-HDLc ratio and triglycerides. CONCLUSION Both interventions promoted weight loss and improvements in fitness and markers of health. The CV program, which included supervised resistance training and higher protein diet menus, promoted greater fat loss, increases in lean mass, and improvements in percent body fat and blood lipids.

Abstract
Objectives. There is limited evidence on the long-term effectiveness of behavioral weight-management interventions, and thus, when conducting health economic modeling, assumptions are made about weight trajectories. The aims of this review were to examine these assumptions made about weight trajectories, the evidence sources used to justify them, and the impact of assumptions on estimated cost-effectiveness. Given the evidence that some psychosocial variables are associated with weight-loss trajectories, we also aimed to examine the extent to which psychosocial variables have been used to estimate weight trajectories and whether psychosocial variables were measured within cited evidence sources. Methods. A search of databases (Medline, PubMed, Cochrane, NHS Economic Evaluation, Embase, PSYCinfo, CINAHL, EconLit) was conducted using keywords related to overweight, weight-management, and economic evaluation. Economic evaluations of weight-management interventions that included modeling beyond trial data were included. Results. Within the 38 eligible articles, 6 types of assumptions were reported (weight loss maintained, weight loss regained immediately, linear weight regain, subgroup-specific trajectories, exponential decay of effect, maintenance followed by regain). Fifteen articles cited at least 1 evidence source to support the assumption reported. The assumption used affected the assessment of cost-effectiveness in 9 of the 19 studies that tested this in sensitivity analyses. None of the articles reported using psychosocial factors to estimate weight trajectories. However, psychosocial factors were measured in evidence sources cited by 11 health economic models. Conclusions. Given the range of weight trajectories reported and the potential impact on funding decisions, further research is warranted to investigate how psychosocial variables measured in trials can be used within health economic models to simulate heterogeneous weight trajectories and potentially improve the accuracy of cost-effectiveness estimates.

Abstract
Introduction Low-income women are disproportionately overweight or obese. The Vermont WISEWOMAN (Well Integrated Screening and Evaluation for Women Across the Nation) program, which serves Vermont women whose annual income is less than 250% of the federal poverty level, pays for members to attend 1 of 2 different evidence-based weight loss programs, Weight Watchers or Curves Complete. Purpose and Objectives We evaluated cost effectiveness of the weight-loss programs, conducted from April 2014 through March 2016, to determine which represented the best investment of WISEWOMAN program funds. Intervention Approach Vermont WISEWOMAN members who were overweight or obese during screening and who identified weight loss as a goal were invited to participate in 1 of the 2 programs on the basis of their place of residence and local Weight Watchers or Curves Complete contractual agreements with the Vermont WISEWOMAN program. Evaluation Methods Program costs and benefits were collected for a 2-year period and used to calculate the cost per participant who completed the program and the cost per participant who achieved the weight reduction goal of a 5% or more loss in body weight. Results The cost per participant achieving the weight reduction goal with Curves Complete ($8,613) was approximately 5 times the cost for Weight Watchers ($1,610). Implications for Public Health Weight Watchers, the evidence-based program with the simplest administrative structure, was significantly more cost effective than Curves Complete. Results suggest that overweight or obese low-income women aged 30 to 64 can lose 5% or more of their body weight more cost effectively through Weight Watchers than through Curves Complete.
