Extensive evidence indicates that fruit and vegetable (F+V) consumption leads to reduced chances of diet related non-communicable diseases (NCDs). However, the F+V consumption levels remain low. This paper investigates the extent to which access to information technologies improves F+V consumption in South Africa. A nationally representative sample of 20,908 households was analysed using the Poisson and logit regression models. The study results indicated that most households do not consume sufficient F+V per day. Only 26% of the household heads consumed F+V at least five times a day. Access to mobile phones, radio, television, and internet was associated with increasing frequency of F+V consumption, and higher chances that a household would consume the minimum recommended levels. The association between the communication technologies and F+V consumption varied. Television access had the highest association with both foods, while internet was only significantly associated with vegetable consumption. Several demographic and socio-economic factors played a key role in shaping F+V consumption patterns. The results show that there is scope to disseminate nutrition awareness and education programs, through mobile phones, internet, radio and television in South Africa. The interventions to promote F+V consumption should be tailored according to the different socio-economic profiles of the population.
大量证据表明,水果和蔬菜(F+V)的消费可降低与饮食相关的非传染性疾病(NCDs)的发病风险。然而,F+V 的消费水平仍然很低。本文调查了获取信息技术在多大程度上能提高南非的 F+V 消费。使用泊松和对数回归模型对 20908 户具有全国代表性的家庭进行了分析。研究结果表明,大多数家庭每天没有摄入足够的 F+V。只有 26%的家庭主妇每天至少食用 F+V 五次。使用手机、广播、电视和互联网与增加 F+V 的食用频率以及家庭更有可能达到最低推荐摄入量有关。通信技术与 F+V 消费之间的关联因技术而异。电视的使用与这两种食物都有很高的关联,而互联网仅与蔬菜的消费显著相关。几个人口统计和社会经济因素在塑造 F+V 消费模式方面发挥了关键作用。结果表明,在南非,通过手机、互联网、广播和电视传播营养意识和教育计划是有一定空间的。促进 F+V 消费的干预措施应根据人口的不同社会经济状况进行调整。
