摘要

背景:多媒体技术因其在教育中的功效而得到公认,为传统健康教育提供了一种补充途径。在南非,社区卫生工作者(CHWs)在改善人口健康方面发挥着关键作用,但往往缺乏全面的卫生知识。本研究探讨利用多媒体教育-娱乐(MM-EE)干预提高资源匮乏乡镇卫生工作者食物和营养素养的有效性。方法:77名参与者完成了基线和干预后6个月的随访调查。MM-EE的干预措施包括以漫画小册子和30秒视频短片的形式讲述短篇故事,内容涉及食物知识、食物标签的使用、膳食准备、计划和饮食行为。材料通过移动消息服务分发,包括WhatsApp(作为主要的社交媒体平台)、彩信和短信。使用R studio 4.3.3版本进行描述性统计、卡方检验、Wilcoxon符号秩检验和多元线性回归。结果:超过70%的参与者被归类为肥胖,18.2%的参与者被归类为超重,导致88.3%的参与者被归类为超重或肥胖。相当大比例的参与者(68.8%)报告患有非传染性疾病。MM-EE干预显著提高了chw的食物和营养素养,反映在膳食准备(干预前43.1% [IQR: 19.6]对干预后62.7% [IQR: 11.7])、计划(干预前58.6% [IQR: 12.1]对干预后67.2% [IQR: 13.4])和整体食物和营养素养(干预前63.0% [IQR: 8.1]对干预后69.4% [IQR: 10.9])的中位数得分提高;p结论:该研究显示了有效的MM-EE干预结果,定位这种健康传播方法适用于提高南非卫生工作者的食物和营养素养。该研究表明,MM-EE方法在提高南非人口的健康知识方面具有潜在的有效性。然而,为了适应更广泛的人口,需要进一步研究可扩展性、可持续性和改进的干预设计,以解决扫盲的各个方面。

Supporting community health workers in South Africa for context-specific food and nutrition literacy: implementation of a multi-media education-entertainment intervention.

Background: Multimedia technology, recognized for its efficacy in education, offers a complementary approach to traditional health education. In South Africa, community health workers (CHWs) play a pivotal role in improving population health, but often lack comprehensive health knowledge. This study explores the effectiveness of using a multimedia education-entertainment (MM-EE) intervention to enhance food and nutrition literacy among CHWs in resource-challenged townships.

Methods: Seventy-seven participants completed a baseline and 6-month post-intervention follow-up survey. The MM-EE intervention comprised short stories conveyed via comic booklets and 30-second video clips, covering food knowledge, use of food labels, meal preparation, planning, and eating behaviour. Materials were distributed via mobile messaging services, including WhatsApp (as the primary social media platform), MMS, and SMS. Descriptive statistics, chi-square tests, Wilcoxon signed-rank tests, and multivariate linear regression were conducted using R studio version 4.3.3.

Results: Over 70% of participants were classified as having obesity, and 18.2% as overweight, leading to 88.3% of participants being classified as overweight or having obesity. A significant proportion of participants (68.8%) reported having an existing non-communicable disease (NCD). The MM-EE intervention significantly improved CHWs' food and nutrition literacy, reflected in improved median scores for meal preparation (43.1% [IQR: 19.6] pre- vs. 62.7% [IQR: 11.7] post-intervention), planning (58.6% [IQR: 12.1] pre- vs. 67.2% [IQR: 13.4] post-intervention), and overall food and nutrition literacy (63.0% [IQR: 8.1] pre- vs. 69.4% [IQR: 10.9] post-intervention; p <.001).

Conclusion: The study showed effective MM-EE intervention outcomes, positioning this method of health dissemination as suitable for improving the food and nutrition literacy of CHWs in South Africa. The study suggests the potential effectiveness of MM-EE approaches to enhance the health knowledge of the South African population. However, adaptation for the wider population will require further research on scalability, sustainability and an improved intervention design to address all dimensions of literacy.
