在乌干达，基于杀虫剂的工具对于控制病媒传播疾病仍然至关重要。确保目标人群对此类工具的公众支持是维持其长期有效性的重要组成部分。然而，关于病媒控制方案在目标家庭中的预期效益和成本，几乎没有量化证据。对乌干达北方古卢和奥亚姆地区的612个家庭进行了一次整群随机抽样调查，当时正值疟疾传播率很高的时期，并开展了室内滞留喷洒试点方案。在调查中进行了离散选择实验，受访者表示他们的偏好不同的IRS方案相对于金钱补偿在一系列实验控制，假设的选择集。使用条件logit回归模型对数据进行分析，以估计受访者愿意接受（WTA）一定数额的金钱补偿，以代替放弃疟疾风险降低。潜类模型被用来分析是否受访者的特征预测WTA。疟疾风险降低10%的平均WTA估计为每年8.94美元，IRS的额外共同效益估计为每轮IRS平均54 - 56美元（取决于杀虫剂类型）。观察到的差异很大：在乌干达北方，五分之四的户主对室内滞留喷雾杀虫剂方案的评价很高，而其余20%的户主则经历了室内滞留喷雾杀虫剂昂贵的副作用（每轮价值在2美元至3美元之间）。属于高价值群体的统计学显著预测因素包括受访者性别，家庭成员的平均年龄，参与以前的IRS，蚊子繁殖的基本知识，以及拥有的蚊帐数量。家庭收入和财富的代理人没有被发现是统计上显着的预测WTA。这项研究表明，像乌干达北方这样疟疾高传播地区的大多数人高度重视使用IRS的病媒控制方案。然而，在感知的副作用（积极和消极）方面存在显著异质性。这对维持公众对这些方案的长期支持具有影响。本文的在线版本（doi：10.1186/s40249-016-0190-1）包含补充材料，可供授权用户使用。
Insecticide-based tools remain critical for controlling vector-borne diseases in Uganda. Securing public support from targeted populations for such tools is an important component in sustaining their long-run effectiveness. Yet little quantitative evidence is available on the perceived benefits and costs of vector control programmes among targeted households. A survey was administered to a clustered random sample of 612 households in Gulu and Oyam districts of northern Uganda during a period of very high malaria transmission and following a pilot indoor residual spray (IRS) programme. A discrete choice experiment was conducted within the survey, in which respondents indicated their preferences for different IRS programmes relative to money compensation in a series of experimentally controlled, hypothetical choice sets. The data were analysed using conditional logit regression models to estimate respondents’ willingness to accept (WTA) some amount of money compensation in lieu of foregone malaria risk reductions. Latent class models were used to analyse whether respondent characteristics predicted WTA. Average WTA is estimated at $8.94 annually for a 10 % reduction in malaria risk, and additional co-benefits of IRS were estimated to be worth on average $54–$56 (depending on insecticide type) per round of IRS. Significant heterogeneity is observed: Four in five household heads in northern Uganda have high valuations for IRS programmes, while the remaining 20 % experience costly side effects of IRS (valued at between $2 and $3 per round). Statistically significant predictors of belonging to the high-value group include respondent gender, mean age of household members, participation in previous IRS, basic knowledge of mosquito reproduction, and the number of mosquito nets owned. Proxies for household income and wealth are not found to be statistically significant predictors of WTA. This study suggests that the majority of people in areas of high malaria transmission like northern Uganda place a high value on vector control programmes using IRS. However, there is significant heterogeneity in terms of the perceived side effects (positive and negative). This has implications for sustaining public support for these programmes in the long-term.
