A lower body mass index at the time of body contouring surgery can optimize surgical options and, ultimately, aesthetic results. With increased emphasis on preoperative evaluation of the massive weight loss patient, the interrelationships between nutrition and exercise on body mass indices have not been well defined.
One hundred thirty-three consecutive massive weight loss patients presented for body contouring. Two-week food logs, weekly exercise regimens, and body mass indices were measured. Outcome variables were assessed by univariate and multivariate analysis.
One hundred fifteen women and 18 men presented, with a mean age of 46.5 +/- 11.0 years, a maximum body mass index of 52.8 +/- 10.6 kg/m2, current body mass index of 32.4 +/- 8.6, change in body mass index of 20.4 +/- 6.5, daily protein intake of 56.9 +/- 18.5 g, and mean exercise of 3.7 days/week. The mean change in body mass index for the bariatric surgery group was 20.9 +/- 6.4 versus 15.9 +/- 6.8 for the self-weight loss group (p = 0.01). Age correlated directly with current body mass index (p = 0.0031) and inversely with exercise (p = 0.0003). Change in body mass index was related to younger age (p = 0.0455), maximum body mass index (p < 0.0001), and bariatric surgery (p = 0.0016), but not protein intake. Exercise five or more times per week was associated with a larger change in body mass index and lower current body mass index (p < 0.0036) than exercising two or fewer times per week (p = 0.0292).
Frequent exercise optimizes body mass index at the time of presentation for body contouring surgery. Further evaluation of the elements of diet will be required to determine its role. Thus, comprehensive post-bariatric surgery or lifestyle programs that promote exercise may increase surgical options and optimize results in body contouring surgery.
在进行身体塑形手术时，较低的体重指数可以优化手术选择，并最终达到美学效果。随着对大量减重患者术前评估的重视，营养与运动对体重指数的相互关系尚未得到很好的定义。
对 133 例连续接受身体塑形的大量减重患者进行了研究。测量了两周的食物记录、每周的运动方案和体重指数。通过单变量和多变量分析评估了结果变量。
115 名女性和 18 名男性患者，平均年龄为 46.5 ± 11.0 岁，最大体重指数为 52.8 ± 10.6kg/m2，当前体重指数为 32.4 ± 8.6，体重指数变化为 20.4 ± 6.5，每日蛋白质摄入量为 56.9 ± 18.5g，平均每周运动 3.7 天。减重手术组的体重指数平均变化为 20.9 ± 6.4，而自我减重组为 15.9 ± 6.8（p=0.01）。年龄与当前体重指数呈正相关（p=0.0031），与运动呈负相关（p=0.0003）。体重指数的变化与年龄较小（p=0.0455）、最大体重指数（p<0.0001）和减重手术（p=0.0016）有关，但与蛋白质摄入无关。每周运动 5 次或以上与体重指数变化较大和当前体重指数较低有关（p<0.0036），而每周运动 2 次或以下与体重指数变化较小和当前体重指数较高有关（p=0.0292）。
频繁运动可优化身体塑形手术时的体重指数。需要进一步评估饮食元素以确定其作用。因此，促进运动的综合性减重手术后或生活方式计划可能会增加手术选择，并优化身体塑形手术的效果。
