Prior evidence suggests that there may be an association between asthma and food insecurity. We sought to describe the prevalence of food insecurity access, defined as having sufficient resources for appropriate foods in Lima, Peru, and evaluate its association with asthma status and control. We analyzed data from 553 children with asthma and 268 healthy controls aged nine to 19 years living in two peri-urban communities in Lima, Peru, in 2013. We used the Household Food Insecurity Access Scale to assess food insecurity. We defined uncontrolled asthma as an asthma control test score ≤19. We used multivariable logistic regressions to determine the relationship between asthma outcomes and food insecurity adjusting for age, sex, socioeconomic status, body mass index, and setting. Average age was 14.2 years (SD 2.7). There was a high prevalence of household food insecurity in our study: 330 participants (40.2%) were food insecure, and average food insecurity access score was 2.7 points (SD 4.2). While being food insecure was not associated with asthma status (OR = 1.23, 95% CI 0.85 to 1.79; = 0.28), it was associated with a higher odds of having uncontrolled asthma (OR = 2.01, 95% CI 1.13 to 3.59; = 0.02). Each one-unit increase in food insecurity score (higher scores indicating more insecurity) was associated with 8% higher odds of having uncontrolled asthma (OR = 1.08, 95% CI 1.02 to 1.14; < 0.01). Worse asthma control was associated with food insecurity. Future studies are needed to better understand the role of food security in determining the success of treatment strategies.
先前的证据表明，哮喘与食物不安全之间可能存在关联。我们旨在描述秘鲁利马的食物不安全获取的流行情况，定义为拥有足够资源以获得适当食物的情况，并评估其与哮喘状况和控制的关系。我们分析了 2013 年来自秘鲁利马两个城郊社区的 553 名哮喘儿童和 268 名健康对照者的数据，这些儿童和对照者的年龄为 9 至 19 岁。我们使用家庭食物不安全获取量表评估食物不安全。我们将未得到控制的哮喘定义为哮喘控制测试评分≤19。我们使用多变量逻辑回归来确定哮喘结果与食物不安全之间的关系，调整了年龄、性别、社会经济地位、体重指数和环境等因素。平均年龄为 14.2 岁（标准差 2.7）。我们的研究中家庭食物不安全的发生率很高：330 名参与者（40.2%）存在食物不安全，平均食物不安全获取评分 2.7 分（标准差 4.2）。虽然食物不安全与哮喘状况无关（比值比=1.23，95%置信区间 0.85 至 1.79；=0.28），但它与发生未得到控制的哮喘的几率较高相关（比值比=2.01，95%置信区间 1.13 至 3.59；=0.02）。食物不安全评分每增加一个单位（较高的分数表示更不安全），与未得到控制的哮喘几率增加 8%相关（比值比=1.08，95%置信区间 1.02 至 1.14；<0.01）。较差的哮喘控制与食物不安全有关。需要进一步研究以更好地了解食品安全在确定治疗策略的成功中的作用。
