To examine the association between level of food security and diabetes self-management among food pantry clients, which is largely not possible using clinic-based sampling methods.
Cross-sectional descriptive study.
Community-based food pantries in California, Ohio and Texas, USA, from March 2012 through March 2014.
Convenience sample of adults with diabetes queuing at pantries (n 1237; 83 % response). Sampled adults were stratified as food secure, low food secure or very low food secure. We used point-of-care glycated Hb (HbA1c) testing to determine glycaemic control and captured diabetes self-management using validated survey items.
The sample was 70 % female, 55 % Latino/Hispanic, 25 % white and 10 % black/African American, with a mean age of 56 years. Eighty-four per cent were food insecure, one-half of whom had very low food security. Mean HbA1c was 8·1 % and did not vary significantly by food security status. In adjusted models, very-low-food-secure participants, compared with both low-food-secure and food-secure participants, had poorer diabetes self-efficacy, greater diabetes distress, greater medication non-adherence, higher prevalence of severe hypoglycaemic episodes, higher prevalence of depressive symptoms, more medication affordability challenges, and more food and medicine or health supply trade-offs.
Few studies of the health impact of food security have been able to examine very low food security. In a food pantry sample with high rates of food insecurity, we found that diabetes self-management becomes increasingly difficult as food security worsens. The efficacy of interventions to improve diabetes self-management may increase if food security is simultaneously addressed.
研究食品救济站受助者的粮食安全水平与糖尿病自我管理之间的关联,而这在很大程度上无法通过基于诊所的抽样方法实现。
横断面描述性研究。
2012年3月至2014年3月期间,美国加利福尼亚州、俄亥俄州和得克萨斯州的社区食品救济站。
在食品救济站排队的成年糖尿病患者便利样本(n = 1237;应答率83%)。抽样的成年人被分为粮食安全、粮食安全程度低或粮食安全程度极低三类。我们使用即时糖化血红蛋白(HbA1c)检测来确定血糖控制情况,并通过经过验证的调查项目获取糖尿病自我管理情况。
样本中70%为女性,55%为拉丁裔/西班牙裔,25%为白人,10%为黑人/非裔美国人,平均年龄56岁。84%的人粮食不安全,其中一半人的粮食安全程度极低。平均HbA1c为8.1%,在不同粮食安全状况下无显著差异。在调整模型中,与粮食安全程度低和粮食安全的参与者相比,粮食安全程度极低的参与者糖尿病自我效能较差、糖尿病困扰更大、药物治疗依从性更低、严重低血糖发作患病率更高、抑郁症状患病率更高、药物支付能力挑战更多,并且在食物与药品或健康用品的权衡上更多。
很少有关于粮食安全对健康影响的研究能够考察粮食安全程度极低的情况。在一个粮食不安全率很高的食品救济站样本中,我们发现随着粮食安全状况恶化,糖尿病自我管理变得越来越困难。如果同时解决粮食安全问题,改善糖尿病自我管理的干预措施的效果可能会提高。
