To investigate dietary health understandings, healthy foods access perceptions and the main sources of nutritional knowledge of residents in three urban communities of varying socio-economic make-up.
An ethnographic approach to primary qualitative data collection, involving frequent visits to study areas over 4 months and in-depth interviews. Interviews were recorded, transcribed verbatim and analysed through an iterative approach.
Yogyakarta, Indonesia.
A purposive sample of 45 participants divided equally among the 3 communities. Participants were mostly female (93 %), aged between 27 and 75 years (mean 47·7) and largely identified as the person responsible for household food-related decisions (93 %).
Three overarching themes emerged: (i) dietary health understandings; (ii) healthy foods access perceptions and (iii) sources of nutritional knowledge. Participants employed multifaceted conceptualisation of dietary health. Most identified healthy foods with traditional plant-based foods, inexpensive and locally available from multiple sources. Thus, all participants perceived healthy foods as highly available in the local environment and most (80 %) as affordable. Reported affordability issues referred to specific foods (particularly animal source products) and were independent of income levels. Participants acquired nutritional knowledge from multiple sources, including many community-based initiatives. These were overall perceived as useful, but also as presenting some limitations.
The variety in dietary health understandings reported by study participants, and their high perceptions of healthy foods availability in the local environment reinforce the idea that individual- and food environment-level determinants of nutritional behaviours are highly contextual.
调查三个不同社会经济构成的城市社区居民的饮食健康认知、健康食品获取感知以及营养知识的主要来源。
采用原始定性数据收集的人种学方法，在 4 个月的时间里频繁访问研究区域，并进行深入访谈。访谈进行了录音、逐字转录，并通过迭代方法进行分析。
印度尼西亚日惹。
在 3 个社区中，每个社区均有 45 名参与者，采用目的性抽样法，参与者的性别构成基本相同（93%为女性），年龄在 27 至 75 岁之间（平均 47.7 岁），且很大程度上作为家庭食品相关决策的负责人（93%）。
出现了 3 个总体主题：（i）饮食健康认知；（ii）健康食品获取感知；（iii）营养知识来源。参与者对饮食健康采用了多方面的概念化。大多数人将健康食品与传统植物性食物、价格低廉且本地多种来源的食物联系起来。因此，所有参与者均认为健康食品在当地环境中高度可获得，而且大多数（80%）认为价格可承受。报告的负担能力问题涉及特定食品（尤其是动物源产品），且与收入水平无关。参与者从多种来源获取营养知识，包括许多社区为基础的举措。这些举措总体上被认为是有用的，但也存在一些局限性。
研究参与者报告的饮食健康认知的多样性，以及他们对当地环境中健康食品的高度感知，强化了这样一种观点，即营养行为的个体和食物环境水平决定因素具有很强的背景依赖性。
