Few studies have documented whether the behavior changes produced by home garden projects have been maintained after completion of the projects.
To determine the benefits and challenges affecting production and consumption of β-carotene-rich vegetables and fruits in a rural South African village 10 years after completion of a home garden project.
This cross-sectional survey assessed gardening practices and household consumption of β-carotene-rich vegetables and fruits using a questionnaire (n = 186). Benefits and challenges affecting production and consumption of β-carotene-rich vegetables and fruits were assessed through focus group discussions.
Thirty-nine percent of the households currently planted β-carotene-rich vegetables and fruits. Major challenges included lack of fencing, animals eating crops, and lack or shortage of water. Planting materials for β-carotene-rich vegetables were sourced from the community nursery, while papaya was grown from its own seed. Shops were the most likely alternative sources of β-carotene-rich vegetables. The frequency of consumption of orange-fleshed sweet potato, butternut, spinach, and papaya when in season differed significantly, with households planting β-carotene-rich vegetables and fruits having more frequent consumption than households not planting these vegetables and fruits. Households planting β-carotene-rich vegetables and fruits were perceived as "well-to-do" and "healthy" households and as "givers".
This study showed that 10 years after the endline evaluation of a home garden project, approximately one-third of the households in the village planted β-carotene-rich vegetables and fruits, which is very similar to the proportion at project completion and a postintervention study that was done 6 years later, despite various challenges, indicating that the practice of planting these vegetables and fruits was continued over the years.
很少有研究记录家庭菜园项目所带来的行为改变在项目完成后是否得以维持。
确定在一个南非乡村家庭菜园项目完成10年后,影响富含β-胡萝卜素的蔬菜和水果生产与消费的益处和挑战。
这项横断面调查通过问卷调查(n = 186)评估了园艺实践以及家庭对富含β-胡萝卜素的蔬菜和水果的消费情况。通过焦点小组讨论评估了影响富含β-胡萝卜素的蔬菜和水果生产与消费的益处和挑战。
目前有39%的家庭种植富含β-胡萝卜素的蔬菜和水果。主要挑战包括缺乏围栏、动物啃食作物以及缺水或水资源短缺。富含β-胡萝卜素的蔬菜的种植材料来自社区苗圃,而木瓜是用自家种子种植的。商店是富含β-胡萝卜素的蔬菜最有可能的替代来源。当季时,橙色果肉甘薯、笋瓜、菠菜和木瓜的消费频率差异显著,种植富含β-胡萝卜素的蔬菜和水果的家庭比未种植这些蔬菜和水果的家庭消费更为频繁。种植富含β-胡萝卜素的蔬菜和水果的家庭被视为“富裕”和“健康”家庭以及“给予者”。
本研究表明,在家庭菜园项目终期评估结束10年后,该村约三分之一的家庭种植富含β-胡萝卜素的蔬菜和水果,这与项目完成时以及6年后进行的一项干预后研究中的比例非常相似,尽管存在各种挑战,这表明多年来种植这些蔬菜和水果的做法得以延续。
