Abstract

OBJECTIVE

Examine the relationship between nutrition knowledge, diet quality, and eating behavior among active-duty US Army Soldiers.

METHODS

Cross-sectional study with data collection in February 2018 via paper surveys during the validation of the Military Eating Behavior Survey.

RESULTS

Among 440 US Army Soldiers, nutrition knowledge was positively and significantly associated with diet quality (b = 0.29, P < 0.001). For every 1-point increase in nutrition knowledge, the Healthy Eating Index-2015 score was expected to increase by 0.29 points. Nutrition knowledge was not significantly associated with skipping breakfast (odds ratio, 1.01; 95% confidence interval, 0.98-1.04) or dining out (odds ratio, 1.01; 95% confidence interval, 0.98-1.03).

CONCLUSIONS AND IMPLICATIONS

The outcomes of this study warrant further investigation to determine what interventions provide the strongest outcomes for improving nutrition knowledge and diet quality, as well as create and support an environment that enhances healthy behaviors regarding nutrition that lead to improved diet quality among active-duty Soldiers.

摘要

目的

研究美国现役陆军士兵的营养知识、饮食质量和饮食行为之间的关系。

方法

采用横断面研究，于2018年2月在军事饮食行为调查验证期间通过纸质调查问卷收集数据。

结果

在440名美国陆军士兵中，营养知识与饮食质量呈显著正相关（b = 0.29，P < 0.001）。营养知识每增加1分，2015年健康饮食指数得分预计增加0.29分。营养知识与不吃早餐（比值比，1.01；95%置信区间，0.98 - 1.04）或外出就餐（比值比，1.01；95%置信区间，0.98 - 1.03）无显著关联。
