Abstract:

Malaria control efforts currently lay emphasis on reducing transmission by limiting human-vector contact. Meanwhile, Mosquito-Avoidance Practices (MAPs) have been shown to be sub-optimal in urban areas, especially among under-five children (U-5C), resulting in high child morbidity and mortality. This study was therefore designed to investigate MAPs among caregivers of U-5C living in Somolu; an urban Local Government Area (LGA) in Lagos State, Nigeria.

A cross-sectional survey was conducted involving 394 female caregivers of U-5C. The LGA was stratified into three layers based on the level of planning and drainage using a geographic information system (GIS). Data were collected using a semi-structured, interviewer-administered questionnaire and were analysed using descriptive statistics and Chi-square test at p=0.05.

Mean age of respondents was 33.6±7.7 years. The proportion who mentioned mosquito nets as a MAP by strata were: S1-59.3%, S2-80.7% and S3-64.3%. Other MAPs reported included: spraying insecticide: S1-20.5%, S2-26.3% and S3-17.1%, shutting door after sunset: S1-9.6%, S2-10.5% and S3-11.4%, and clearing surroundings: S1-2.9%, S2-5.3% and S3-2.9%. Ownership of bed nets was: S1-76.0%, S2-75.4% and S3-68.6%, and out of these, S1-73.1%, S2-70.7% and S3-72.4% reported that their child slept under the net the night before the survey.

The most common mosquito-avoidance practice among caregivers of under-five children was the use of bed nets, and this did not differ by level of planning and drainage of the study site. Therefore, strategies to improve and sustain the use of bed nets and to promote the use of other effective mosquito-avoidance practices should be encouraged.
