对南非夸祖鲁-纳塔尔省城郊家庭的水果和蔬菜的供应和消费情况进行了评估。使用包含未量化食物频率问题的调查问卷对 400 名随机选择的 6 年级和 7 年级学生的照顾者进行了采访。通过重复的 24 小时饮食回忆，对学习者、看护者和家庭中 2 至 5 岁儿童的饮食摄入量进行了量化。通常的家庭水果和蔬菜消费量通过三个生活标准衡量标准（LSM）类别来表示。 2至5岁儿童的人均水果和/或蔬菜摄入量为99克，看护者为124克。对于消费者而言，水果和/或蔬菜占纤维（16-21%）、钙（13-21%）、维生素A（27-31%）和维生素C（47-62%）的膳食总摄入量。对于每天不消费水果（n=297）和蔬菜（n=178）的家庭来说，成本是主要限制因素（75%）。在所有家庭中，52% 拥有果树，25% 拥有菜园。动物破坏蔬菜是 59% 蔬菜种植者的主要制约因素。水果和蔬菜的家庭消费量比 LSM 类别有所增加。 LSM 较高组的护理人员更有可能使用印刷材料来获取有关健康饮食的信息，种植果树，对蔬菜园艺充满信心，并出售一些农产品。为了使社会经济地位较低的城郊人口能够更频繁地消费更多种类的水果和蔬菜，购买这些食品的成本需要由政府和企业部门解决。家庭应进一步获得支持，以克服阻碍家庭菜园成功的限制因素。
Availability and consumption of fruits and vegetables were assessed in peri-urban households in KwaZulu-Natal Province, South Africa. Caregivers of 400 randomly selected grade 6 and 7 learners were interviewed using a questionnaire that included unquantified food frequency questions. Using a repeated 24-h dietary recall, dietary intake was quantified for learners, caregivers and 2- to 5-year-old children in the household. Usual household fruit and vegetable consumption was expressed over three Living Standard Measure (LSM) categories. Average per capita intake of fruit and/or vegetables was 99g for 2- to 5-year-old children and 124g for caregivers. For consumers, fruits and/or vegetables contributed towards total dietary intake of fibre (16-21%), calcium (13-21%), vitamin A (27-31%) and vitamin C (47-62%). For households not consuming fruits (n=297) and vegetables (n=178) daily, cost was the major constraint (75%). Of all households, 52% had fruit trees and 25% had a vegetable garden. Animals destroying vegetables was the major constraint to 59% of vegetable growers. Household consumption of fruits and vegetables increased over the LSM categories. Caregivers in the higher LSM group more likely used printed material for information on healthy eating, had fruit trees, were confident about vegetable gardening and sold some of their produce. To enable peri-urban populations of low socio-economic status to consume more frequently a bigger variety of fruits and vegetables, the cost of purchasing these food items needs to be addressed by government and business sector. Households should further receive support to overcome constraints which hamper the success of home gardens.
