To identify barriers to appropriate dietary behavior in an urban, low-income population of patients with type 2 diabetes and to examine a new instrument in the identification of these barriers in this population.
A cross-sectional survey was developed, validated, and anonymously administered to low-income adults with type 2 diabetes in an academic family medicine physician group practice with a pharmacist-operated diabetes education and comanagement service. The survey consisted of three key subscales: determinants of food selection, importance of life challenges, and barriers to appropriate eating.
The survey was administered to 98 patients with a mean age of 51.98 years, a mean duration of diabetes of 9.76 years, and a mean hemoglobin A1c of 7.99%. When asked to rate factors most important in food selection, the highest mean responses were taste (3.97 out of 5) and cost (score of 3.94 out of 5). Barriers that the majority of respondents agreed or strongly agreed were important included: stress causing over-eating or unhealthy food choices, difficulty resisting the temptation to eat unhealthy food, and healthy food being too expensive. The Cronbach's Alpha for the subscales of food selection, importance of life challenges, and barrier were 0.673, 0.853, and 0.786, respectively.
In a low-income, urban, predominantly African American and Caucasian diabetic population, cost of healthy food, stress-related inappropriate eating, and the temptation to eat unhealthy food were the most frequently reported barriers to healthy eating. Diabetes education programs serving similar populations should evaluate the presence of these barriers. The survey instrument was a reliable measure of the constructs it purported to measure.
确定 2 型糖尿病城市低收入人群适当饮食行为的障碍，并在该人群中检验一种识别这些障碍的新工具。
开发了一个横断面调查，对一家学术家庭医学医生集团实践中由药剂师运营的糖尿病教育和共同管理服务的 2 型糖尿病低收入成年人进行了验证和匿名管理。该调查包括三个关键子量表：食物选择的决定因素、生活挑战的重要性和适当饮食的障碍。
该调查共向 98 名平均年龄为 51.98 岁、糖尿病平均病程为 9.76 年、血红蛋白 A1c 平均为 7.99%的患者进行了调查。当被要求对食物选择最重要的因素进行评分时，最高的平均评分为口味（5 分制得 3.97 分）和价格（5 分制得 3.94 分）。大多数受访者同意或强烈同意的重要障碍包括：压力导致过度进食或选择不健康的食物、难以抵制吃不健康食物的诱惑、以及健康食品太贵。食物选择、生活挑战和障碍的子量表的 Cronbach's Alpha 分别为 0.673、0.853 和 0.786。
在一个低收入、城市、以非裔美国人和白人为主要人口的 2 型糖尿病人群中，健康食品的成本、与压力相关的不适当饮食以及吃不健康食品的诱惑是健康饮食的最大障碍。为类似人群提供的糖尿病教育计划应评估这些障碍的存在。该调查工具是对其声称要衡量的结构的可靠测量。
