Food-based interventions can reduce the prevalence of undernutrition and improve household food security, but nutritious and accessible foods may be underutilized. In Ecuador, eggs are inexpensive and widely available, but while they are a valuable source of essential nutrients for infants and young children, medical advice and community-based information have limited their inclusion in infants' diets.
A qualitative component was conducted to understand local perceptions, knowledge, and practices to complement a randomized control trial that studied the effect of introducing eggs on nutritional status and growth in infants from 6 to 9 months in rural communities in the highland province of Cotopaxi, Ecuador.
The qualitative inquiry consisted of key informant interviews, focus group discussions (FGDs), and structured observations in order to understand perceptions, knowledge, and practices related to household egg consumption and to the introduction of eggs in infants' diets.
The two principal findings were that: (i) eggs are an available and culturally acceptable food source although they are not always a part of the diet; and (ii) perceptions and practices related to household consumption and the introduction of eggs into the diet of infants are shaped by local knowledge and practices, which are shaped by biomedical information and advice provided by public health professionals.
Through an effective food-based intervention that includes qualitative research and a social marketing component, the behaviors of mothers and other caregivers can be modified, enabling children to realize the nutritional advantages of early introduction of eggs into their diet.
基于食物的干预措施可以降低营养不良的发生率并改善家庭粮食安全,但营养丰富且易于获取的食物可能未得到充分利用。在厄瓜多尔,鸡蛋价格低廉且随处可得,然而尽管它们是婴幼儿必需营养素的重要来源,但医学建议和社区信息却限制了其在婴儿饮食中的添加。
开展一项定性研究,以了解当地的认知、知识和做法,作为对一项随机对照试验的补充。该随机对照试验研究了在厄瓜多尔高地科托帕希省农村社区,给6至9个月大的婴儿引入鸡蛋对其营养状况和生长的影响。
定性调查包括关键信息访谈、焦点小组讨论(FGD)和结构化观察,以了解与家庭鸡蛋消费以及在婴儿饮食中引入鸡蛋相关的认知、知识和做法。
两个主要发现是:(i)鸡蛋是一种可获取且在文化上可接受的食物来源,尽管它们并不总是饮食的一部分;(ii)与家庭消费以及在婴儿饮食中引入鸡蛋相关的认知和做法受到当地知识和做法的影响,而当地知识和做法又受到公共卫生专业人员提供的生物医学信息和建议的影响。
通过一项包括定性研究和社会营销部分的有效基于食物的干预措施,可以改变母亲和其他照顾者的行为,使儿童能够认识到早期在饮食中引入鸡蛋的营养益处。
