Assesment of Insecticide Treated Nets Coverage for Malaria Control in Kafta-Humera District, Tigray: Possession versus Use by High-risk Groups

Abstract

Abstract
Background: In endemic areas, children under five and pregnant women are vulnerable to malaria and are likely to
benefit most from the use of mosquito nets. Use of insecticide treated nets (ITNs) for protection against mosquito bite
during sleep is highly effective. Nevertheless, prioritization pertaining to the use of nets does not seem to be optimal in
most endemic setups.
Objective: To examine the status of ITNs coverage, use and its determinants for malaria control among children under
five and/or pregnant women in Kafta-Humera District in Tigray Regional State.
Methods: A comparative cross-sectional quantitative study was conducted in the rural and urban areas of the District.
Qualitative data were also collected through focus group discussions (FGDs) to identify views of participants,
pertaining to possession and utilization. An early morning survey was also carried out in order to observe the actual
behavior of the community towards net use.
Result: Net and ITN possession was 84.5% and 80.0% for rural, but 96.1% and 91.1% for urban settings, respectively.
Net possession was higher among urban (OR 3.33, 95%CI 1.39, 7.98) compared to rural areas. Observed net and ITN
use during the preceding night by children under five years of age was 68.6% and 67.0% for rural; and 84.6% and
79.5% for urban areas, respectively. Likewise, similar practice for net and ITN in 52.1% and 64.7% of pregnant
women was observed in rural and urban areas, respectively. The FGD results of this study suggested that lower net
possession in rural areas could be due to insufficiency of mosquito net provision and inequity during distribution.
Occupation, family size in rural areas; radio possession in urban areas and relative wealth and number of sleeping
places had significant effect in both settings to own a net. Relative wealth, radio possession, malaria education
message in rural and occupation in both settings had a positive effect on net use.
Conclusion: Not all nets owned by the households were being utilized properly. Yet, maldistribution and shortage of
ITN were also observed within rural and urban settings. Effective Information, Education and Communication (IEC)
should be promoted and continuous availability of ITNs should be in place to achieve effective control of malaria
among the high-risk groups. [Ethiop.J.Health Dev. 2008;22(3):259-267]
