Food and activity factors may have an impact on weight in the general population, but little is known about how this affects postbariatric surgery weight loss.
To understand the impact of environmental food and activity factors on weight loss after bariatric surgery.
A multidisciplinary integrated health system with an accredited bariatric surgery program.
An institutional review board-approved retrospective review of patients who underwent bariatric surgery from 2001-2018 was completed. Food security, food retailers, and activity factors associated with postoperative percentage of total body weight loss (TBWL) at short-term (1-2 yr), medium-term (3-5 yr), and long-term (≥6 yr) follow-up were evaluated.
Overall, 1673 patients were included; 90% experienced ≥20% TBWL in the short term and 65% in the long term. No differences in mean TBWL were observed for food deserts or areas with high versus low food insecurity. Mean TBWL was significantly different for low versus high healthy food density (32.5% versus 33.4%, P = .024) and low versus high fitness facility density (32.6% versus 33.4%, P = .048) at short-term follow-up. Increased mean TBWL was observed for counties with more versus less exercise opportunities at short and medium-term follow-up (33.4% versus 32.5%, P = .025; 31.2% versus 29.7%, P = .019).
Patients experienced significant TBWL after bariatric surgery. Living in a food desert or area with high food insecurity did not significantly impact mean TBWL. Healthy food density, fitness facility density, and exercise opportunities had a short- to medium-term impact on TBWL. These data can be used to support patients to maximize the benefits of bariatric surgery.
食物和活动因素可能会对普通人群的体重产生影响，但人们对这些因素如何影响减重手术后的体重减轻知之甚少。
了解环境食物和活动因素对减重手术后体重减轻的影响。
一个拥有认证减重手术项目的多学科综合健康系统。
对 2001 年至 2018 年间接受减重手术的患者进行了机构审查委员会批准的回顾性研究。评估了与短期（1-2 年）、中期（3-5 年）和长期（≥6 年）随访时术后体重百分比下降（TBWL）相关的食物保障、食品零售商和活动因素。
共有 1673 例患者入选；90%的患者在短期内体重减轻≥20%，65%的患者在长期内体重减轻≥20%。在食物荒漠或食物保障程度高或低的地区，TBWL 的平均值没有差异。在短期随访时，低健康食品密度与高健康食品密度（32.5%比 33.4%，P=0.024）和低健身设施密度与高健身设施密度（32.6%比 33.4%，P=0.048）的 TBWL 平均值差异显著。在短期和中期随访时，与运动机会较少的县相比，运动机会较多的县的 TBWL 平均值更高（33.4%比 32.5%，P=0.025；31.2%比 29.7%，P=0.019）。
患者在减重手术后经历了显著的 TBWL。生活在食物荒漠或食物保障程度高的地区并不显著影响 TBWL 的平均值。健康食品密度、健身设施密度和运动机会对 TBWL 有短期至中期的影响。这些数据可用于支持患者最大限度地发挥减重手术的益处。
