背景登革热是一种新出现的媒介疾病，在尼泊尔暴发频繁，对公众健康构成了重大威胁。登革热控制活动大多是暴发驱动的，仍然缺乏系统的干预措施，而大多数人缺乏与健康有关的知识和做法。移动短信服务是一种低成本的健康促进干预措施，可以提高受影响社区的登革热预防知识和做法。本研究旨在探讨移动短信干预在改善登革热控制实践中的可接受性、适宜性和有效性。方法采用混合方法设计和干预的实施研究。将300户家庭分为3组，即1个对照组、1个登革热预防单张(DPL)干预组和1个DPL+流动短信干预组(DPL+SMS)。我们使用结构化问卷收集参与者关于登革热预防知识和行为的信息。我们对主要信息提供人进行了深入访谈，以衡量干预措施的可接受性和适当性。采用均数标准差(SD)、单因素方差分析、配对t检验和回归分析等方法评价干预效果。结果干预组的平均知识差异(32.713.7SD比13.3+/-8.8SD)和平均实践差异(27.9+/-11.4SD比4.9+/-5.4SD)显著高于单纯干预组(p=0.000)。多因素分析显示，DPL+短信干预有效，与对照组相比，知识增加28.6分，实践增加28.1分。研究参与者和主要利益攸关方认为干预是可以接受和适当的。感知障碍包括专有网络用户和偏远地区网络差，而促成因素包括手机普及率、低成本和分担责任。结论移动短信是一种有效、可接受和适当的健康干预措施，可改善社区的登革热预防实践。这一干预措施可以作为预防登革热和其他疾病的健康教育的一种很有前途的工具。
BackgroundDengue is an emerging vector disease with frequent outbreaks in Nepal that pose a major threat to public health. Dengue control activities are mostly outbreak driven, and still lack systematic interventions while most people have poor health-related knowledge and practices. Mobile Short Message Service (SMS) represents a low-cost health promotion intervention that can enhance the dengue prevention knowledge and practices of the affected communities. This study aimed to explore the acceptability, appropriateness, and effectiveness of mobile SMS intervention in improving dengue control practices.MethodsThis study was an implementation research that used mixed-methods design with intervention. A total of 300 households were divided into three groups, i.e. one control group, one dengue prevention leaflet (DPL) only intervention group and one DPL with mobile SMS intervention group (DPL+SMS). We used a structured questionnaire to collect information regarding participants' knowledge and practice of dengue prevention. We conducted in-depth interviews with key informants to measure acceptability and appropriateness of intervention. Mean difference with standard deviation (SD), one-way ANOVA, paired t-test and regression analyses were used to assess the effectiveness of the interventions. Thematic analysis was used to assess the acceptability, and appropriateness as well as barriers and enablers of the intervention.ResultsThe DPL+SMS intervention produced significantly higher mean knowledge difference (32.713.7 SD vs. 13.3 +/- 8.8 SD) and mean practice difference (27.9 +/- 11.4 SD vs 4.9 +/- 5.4 SD) compared to the DPL only group (p =0.000). Multivariate analysis showed that the DPL+SMS intervention was effective to increase knowledge by 28.6 points and practice by 28.1 points compared to the control group. The intervention was perceived as acceptable and appropriate by the study participants and key stakeholders. Perceived barriers included reaching private network users and poor network in geographically remote areas, while enabling factors included mobile phone penetration, low cost, and shared responsibility.Conclusions Mobile SMS is an effective, acceptable and appropriate health intervention to improve dengue prevention practices in communities. This intervention can be adopted as a promising tool for health education against dengue and other diseases.
