The objective of this study was to evaluate the effect of a 32-week personalized Polar weight management program (PWMP) compared with standard care (SC) on body weight, body composition, waist circumference, and cardiorespiratory fitness in overweight or obese adults.
Overweight or obese (29 +/- 2 kg/m(2)) men and women (n = 74) 38 +/- 5 years of age were randomly assigned into either PWMP (men = 20, women = 21) or SC (men = 15, women = 18). Both groups managed their own diet and exercise program after receiving the same standardized nutrition and physical activity advice. PWMP also received a weight management system with literature to enable the design of a personalized diet and exercise weight loss program. Body weight and body composition, waist circumference, and cardiorespiratory fitness were measured at weeks 0, 16, and 32.
Eighty percent of participants completed the 32-week intervention, with a greater proportion of the dropouts being women (PWMP: 2 men vs. 7 women; SC: 2 men vs. 4 women). At 32 weeks, PWMP completers had significantly (p < 0.001) greater losses in body weight [6.2 +/- 3.4 vs. 2.6 +/- 3.6 (standard deviation) kg], fat mass (5.9 +/- 3.4 vs. 2.2 +/- 3.6 kg), and waist circumference (4.4 +/- 4.5 vs. 1.0 +/- 3.6 cm). Weight loss and fat loss were explained by the exercise energy expenditure completed and not by weekly exercise duration.
More effective weight loss was achieved after treatment with the PWMP compared with SC. The results suggest that the PWMP enables effective weight loss through tools that support self-monitoring without the requirement of more costly approaches to program supervision.
本研究的目的是评估一项为期32周的个性化宝尔体重管理计划（PWMP）与标准护理（SC）相比，对超重或肥胖成年人的体重、身体成分、腰围和心肺适能的影响。
年龄在38±5岁的超重或肥胖（29±2kg/m²）男性和女性（n = 74）被随机分为PWMP组（男性 = 20，女性 = 21）或SC组（男性 = 15，女性 = 18）。两组在接受相同的标准化营养和体育活动建议后，自行管理各自的饮食和锻炼计划。PWMP组还获得了一个体重管理系统及相关文献，以设计个性化的饮食和锻炼减肥计划。在第0周、16周和32周时测量体重、身体成分、腰围和心肺适能。
80%的参与者完成了32周的干预，其中退出者中女性比例更高（PWMP组：2名男性对7名女性；SC组：2名男性对4名女性）。在32周时，PWMP组的完成者在体重[6.2±3.4对2.6±3.6（标准差）kg]、脂肪量（5.9±3.4对2.2±3.6kg）和腰围（4.4±4.5对1.0±3.6cm）方面的减轻幅度显著更大（p < 0.001）。体重减轻和脂肪减少是由完成的运动能量消耗所解释的，而不是每周的运动时长。
与SC相比，PWMP治疗后实现了更有效的体重减轻。结果表明，PWMP通过支持自我监测的工具实现了有效的体重减轻，而无需采用成本更高的计划监督方法。
