Abstract

Background: diabetes is a complex disease that requires multiple strategies for glycemic control. The most challenging part is acquiring healthy eating practices. What is needed is to keep patients well informed and involved with their disease; for this, standardized, reliable instruments are required that allow evaluating the dietary practices in this population.

Objective: to build and to validate a highly reliable evaluation scale of feeding habits in patients with diabetes type 2.

Methodology: a cross-sectional design for the construction and validation of an evaluation scale for feeding habits in diabetes 2 patients. There were listed 63 questions subjected to review and statistics analysis that reduced it into a 30 ítems scale that was applied to 495 diabetes 2 patients in a first level attention clinic. There were used exploratory factorial analysis, sphericity Bartlett test, KMO, total variance explained, Spearman's r-test and Cronbach's alpha.

Results: a final version was obtained containing 30 ítems distributed in 8 dimensions with 3 response options on the Likert scale, with a Cronbach's alpha of 0.811. The exploratory factor analysis showed factor loads > 0.30. The total explained variance threw eight principal components; the KMO test = 0.833, Bartlett's test of sphericity, p = 0.000.

Conclusion: the scale to evaluate eating practices in patients with type 2 diabetes has the validity and high reliability to be able to apply it to this population.

.背景：糖尿病是一种复杂的疾病，需要采取多种策略控制血糖。最具挑战性的部分是获得健康的饮食习惯。我们需要让患者充分了解并参与到他们的疾病中来；为此，我们需要标准化、可靠的工具来评估这一人群的饮食习惯。方法：采用横断面设计，构建并验证糖尿病 2 型患者饮食习惯评估量表。方法：采用横断面设计，构建并验证 2 型糖尿病患者进食习惯评估量表。对列出的 63 个问题进行审查和统计分析，将其缩减为 30 个项目的量表，并应用于一家一级护理诊所的 495 名 2 型糖尿病患者。结果：最终版本包含 30 个项目，分布在 8 个维度上，在李克特量表上有 3 个回答选项，Cronbach's alpha 为 0.811。探索性因子分析显示因子载荷大于 0.30。结论：评价 2 型糖尿病患者饮食习惯的量表具有有效性和高可靠性，可用于该人群。

期刊介绍： The journal Nutrición Hospitalaria was born following the SENPE Bulletin (1981-1983) and the SENPE journal (1984-1985). It is the official organ of expression of the Spanish Society of Clinical Nutrition and Metabolism. Throughout its 36 years of existence has been adapting to the rhythms and demands set by the scientific community and the trends of the editorial processes, being its most recent milestone the achievement of Impact Factor (JCR) in 2009. Its content covers the fields of the sciences of nutrition, with special emphasis on nutritional support.
