Food insecurity (FI) is defined as "the limited or uncertain access to adequate food." One root cause of FI is living in a food desert. FI rates among people with cystic fibrosis (CF) are higher than the general United States (US) population. There is limited data on the association between food deserts and CF health outcomes. We conducted a retrospective review of people with CF under 18 years of age at a single pediatric CF center from January to December 2019 using demographic information and CF health parameters. Using a Geographic Information System, we conducted a spatial overlay analysis at the census tract level using the 2015 Food Access Research Atlas to assess the association between food deserts and CF health outcomes. We used multivariate logistic regression analysis and adjusted for clinical covariates and demographic covariates, using the Child Opportunity Index (COI) to calculate odds ratios (OR) with confidence intervals (CI) for each health outcome. People with CF living in food deserts and the surrounding regions had lower body mass index/weight-for-length (OR 3.18, 95% CI: 1.01, 9.40, ≤ 0.05 (food desert); OR 4.41, 95% CI: 1.60, 12.14, ≤ 0.05 (600 ft buffer zone); OR 2.83, 95% CI: 1.18, 6.76, ≤ 0.05 (1200 ft buffer zone)). Food deserts and their surrounding regions impact pediatric CF outcomes independent of COI. Providers should routinely screen for FI and proximity to food deserts. Interventions are essential to increase access to healthy and affordable food.
食品不安全（FI）被定义为“获取充足食物的有限或不确定”。造成 FI 的一个根本原因是生活在食品荒漠地区。囊性纤维化（CF）患者的 FI 发生率高于美国普通人群。关于食品荒漠与 CF 健康结果之间的关联，数据有限。我们对 2019 年 1 月至 12 月在一家儿科 CF 中心的 18 岁以下 CF 患者进行了回顾性研究，使用人口统计学信息和 CF 健康参数。我们使用地理信息系统，在普查区层面进行空间叠加分析，使用 2015 年食品获取研究地图集评估食品荒漠与 CF 健康结果之间的关联。我们使用多元逻辑回归分析，并根据临床协变量和人口统计学协变量进行调整，使用儿童机会指数（COI）计算每个健康结果的比值比（OR）和置信区间（CI）。生活在食品荒漠及其周边地区的 CF 患者的体质指数/体重长度比较低（OR3.18，95%CI：1.01，9.40， ≤0.05（食品荒漠）；OR4.41，95%CI：1.60，12.14，≤0.05（600 英尺缓冲带）；OR2.83，95%CI：1.18，6.76，≤0.05（1200 英尺缓冲带））。食品荒漠及其周边地区对儿科 CF 结果的影响独立于 COI。提供者应定期筛查 FI 和接近食品荒漠的情况。必须采取干预措施，以增加获得健康和负担得起的食物的机会。
