摘要

背景:健康饮食是保持长期健康的关键因素。在此背景下,除了促进健康的食品环境外,居民的营养健康素养(NHL)和食品素养(FL)也很重要。本文介绍了 2021 年奥地利营养素养调查(Austrian Nutrition Literacy Survey 2021)中使用的两种测量居民营养素养的简易工具的开发和验证情况:方法:对营养健康素养测量工具(营养健康素养量表;NHLS)进行了改编和进一步开发。为了测量FL,对Poelman等人的 "自我感觉食物素养量表"(SPFL-SF)进行了修改和缩短。2021 年在奥地利对近 3000 名 18 岁及以上的参与者进行了网络调查,根据调查数据对这些工具进行了验证。为了评估问卷的因子有效性/维度性,我们对问卷进行了探索性和确认性因子分析。此外,还使用 Cronbach's alpha、ordinal alpha 和 McDonald's omega 评估了内部一致性:结果:两种工具都显示出极佳的数据模型拟合度。NHLS 也显示出极佳的内部一致性(α = 0.91),而 SPFL-SF 除一个子维度(抵制诱惑 α = 0.61)外,其他维度都显示出足够的内部一致性(α 在 0.70 和 0.89 之间)。此外,从项目的分布来看,测量结果是可以理解的,也是合适的,这一点可以从样本中没有缺失值得到证明。此外,两种工具的项目在难度或一致性方面也存在差异:NHLS和SPFL-SF是测量普通成年人NHL和FL的可靠有效的工具。测量营养素养不同方面的简明工具可轻松用于营养或评估研究。还需要进一步研究其他方面的有效性。

Brief instruments for measuring nutrition literacy - the Nutrition Health Literacy Scale and the Self-Perceived Food Literacy Scale Short Form.

Background: A healthy diet is a critical factor in maintaining long-term health. In addition to a health-promoting food environment, the nutrition health literacy (NHL) and food literacy (FL) of the population are important in this context. This paper describes the development and validation of two short instruments to measure the nutrition literacy of the population, used in the Austrian Nutrition Literacy Survey 2021.

Methods: An instrument to measure NHL (Nutrition Health Literacy Scale; NHLS) has been adapted and further developed. To measure FL, the Self-perceived Food Literacy Scale by Poelman et al. has been modified and shortened (SPFL-SF). Validation of the instruments was based on data from a web survey conducted in Austria in 2021 with almost 3,000 participants aged 18 years and older. Exploratory and confirmatory factor analyses were performed to assess the factorial validity/dimensionality of the instruments. Additionally, internal consistency was assessed using Cronbach's alpha, ordinal alpha, and McDonald's omega.

Results: Both instruments demonstrate excellent data-model fit. The NHLS also shows excellent internal consistency (α = 0.91), while the SPFL-SF displays a sufficient internal consistency for all (α between 0.70 and 0.89) but one sub-dimension (resisting temptation α = 0.61). Furthermore, the distribution of the items indicates that the measures are understandable and suitable, as evidenced by the absence of missing values in the sample. In addition, the items of both instruments differ in their level of difficulty or agreement.

Conclusions: The NHLS and SPFL-SF are reliable and valid instruments for measuring NHL and FL in the general adult population. The brief instruments measuring the different aspects of nutrition literacy can be easily used in nutritional or evaluation studies. Further work is required to investigate other aspects of validity.

期刊介绍: Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered. Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies. In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
