KINET: a social marketing programme of treated nets and net treatment for malaria control in Tanzania, with evaluation of child health and long-term survival

Abstract

We present a large-scale social marketing programme of insecticide-treated nets in 2 rural districts in southwestern Tanzania (population 350 000) and describe how the long-term child health and survival impact will be assessed. Formative and market research were conducted in order to understand community perceptions, knowledge, attitudes and practice with respect to the products to be socially marketed. We identified Zuiu Mbu (Kiswahili for 'prevent mosquitoes') as a suitable brand name for both treated nets and single-dose insecticide treatment sachets. A mix ofpublic and private sales outlets is used for distribution. In the first stage of a stepped introduction 3 1 net agents were appointed and trained in 18 villages: 15 were shop owners, 14 were village leaders, 1 was a parish priest and 1 a health worker. For net treatment 37 young people were appointed in the same villages and trained as agents. Further institutions in both districts such as hospitals, development projects and employers were also involved in distribution. Promotion for both products was intense and used a variety of channels. A total of 22 410 nets and 8072 treatments were sold during the first year: 18 months after launching, 46% of 312 families with children aged under 5 years reported that their children were sleeping under treated nets. A strong evaluation component in over 50 000 people allows assessment of the long-term effects of insecticide-treated nets on child health and survival, anaemia in pregnancy, and the costs of the intervention. This evaluation is based on cross-sectional surveys, and case-control and cohort studies.

Free Distribution or Cost-Sharing? Evidence from a Randomized Malaria Prevention Experiment

“…Cost-sharing programs often have a "social marketing" component, which uses mass media communication strategies and branding to increase the consumer's willingness to pay (PSI, 2003;Schellenberg, et al 1999 and2001).…”

The London School of Hygiene and Tropical Medicine: a new century of malaria research

“…If high levels of compliance are required at the individual level to afford protection at the population level, net distribution should be regarded as a public health measure (like vaccination) and should be managed as such. Alternatively, if individual nets protect individual users, net use can be viewed as a personal choice (like contraceptive use) -in which case their uptake could be promoted through health education initiatives but their provision could be managed through the commercial sector (Schellenberg et al 1999). Jo Lines, Kara Hanson and Caroline Jones are studying the effects of these two different approaches to ITBN distribution in Tanzania and also trying to answer the vexed questions of whether social marketing is an effective means of distributing a (relatively) expensive health product (i.e.…”

Investigating the Important Correlates of Maternal Education and Childhood Malaria Infections

“…Malaria prevention messages were also disseminated at public health rallies, which were disproportionately attended by educated mothers and as such better, allowed them to benefit from the health education messages. 48 Given these outlined pathways, a better understanding of these relationships will enhance malaria control efforts through implementation of more holistic programs that focus on not only understanding the behavior of malaria vectors and the disease epidemiology but also, relating malaria control to other non-health factors, like education, for effective and more sustainable malaria control programs.…”
