Although cognitive functioning and health literacy are related to weight loss 1year following bariatric surgery, the influence of health numeracy (i.e., health-related mathematical abilities) is unknown. In addition, further research is needed to examine the impact of all these factors on longer-term weight loss outcomes to determine if they influence the ability to maintain weight loss.
Single bariatric center.
Patients (N = 567) who underwent bariatric surgery from 2014-2017 completed a brief survey including current weight. Retrospective chart reviews were conducted to gather information from the presurgical evaluation including weight, body mass index (BMI), health literacy, health numeracy and score on a cognitive screener.
Among participants in the weight loss period (< 2 years postsurgery), health literacy, health numeracy and cognitive functioning were not related to change in BMI (ΔBMI), percent total weight loss (%TWL) or percent excess weight loss (%EWL). However, for participants in the weight maintenance period (2-4 years postsurgery), higher health literacy scores were related to greater change in ΔBMI, and higher health numeracy scores were related to greater ΔBMI, %TWL, and %EWL.
Although health literacy and health numeracy did not predict weight loss outcomes for those in the initial weight loss period, they were related to weight outcomes for participants in the weight maintenance period. This suggests that health literacy and health numeracy may play a role in facilitating longer-term weight maintenance among patients who undergo bariatric surgery. Clinicians conducting presurgical psychosocial evaluations should consider routinely screening for health literacy and health numeracy.
尽管认知功能和健康素养与减重手术后 1 年的体重减轻有关，但健康算数能力（即与健康相关的数学能力）的影响尚不清楚。此外，需要进一步研究所有这些因素对长期减重结果的影响，以确定它们是否影响维持体重减轻的能力。
单一减重中心。
2014 年至 2017 年间接受减重手术的患者（N=567）完成了一项简短的调查，其中包括当前体重。对病历进行回顾性审查，以从术前评估中收集信息，包括体重、体重指数（BMI）、健康素养、健康算数能力和认知筛查分数。
在减重期间（<2 年手术后）的参与者中，健康素养、健康算数能力和认知功能与 BMI 的变化（ΔBMI）、总体重减轻百分比（%TWL）或超重减轻百分比（%EWL）无关。然而，对于处于体重维持期（2-4 年手术后）的参与者，较高的健康素养分数与 ΔBMI 的变化较大相关，较高的健康算数分数与 ΔBMI、%TWL 和 %EWL 的变化较大相关。
尽管健康素养和健康算数能力不能预测最初减重期间的减重结果，但它们与体重维持期间参与者的体重结果相关。这表明，健康素养和健康算数能力可能在促进接受减重手术的患者长期维持体重方面发挥作用。进行术前心理社会评估的临床医生应考虑常规筛查健康素养和健康算数能力。
