Risk Factors – ITN Guinea DHS 2018

Period: 2021–2022 · Role: Lead Data Analyst · Country: Guinea

Overview

Analysis of the 2018 Guinea Demographic and Health Survey (DHS) to identify determinants of ownership and use of insecticide-treated nets (ITNs) at both household and individual levels. Understanding the factors influencing household ITN ownership and usage among those with access will enable the Guinea National Malaria Control Programme to design targeted interventions aimed at increasing bed net coverage and utilization.

Key Highlights

Main variables: wealth quintiles, education level, urban/rural setting, Age of household head, Age of individual, Sex of household head, Sex of individual, Household size, Number of rooms, Marital status, Children under five, Pregnant status, Region.
Two main outcomes: ITN ownership and ITN use the previous night (among those with access).
Accounted for complex survey design: weights, strata, and clusters.

Methods & Tools

Survey-weighted logistic regression models were implemented in R (survey, srvyr, dplyr, ggplot2, tmap) to estimate adjusted odds ratios and visualize disparities.

Deliverables

Tables and figures for manuscript and policy brief.
Fully reproducible R scripts (data cleaning, indicator generation, modeling).

Impact

Evidence to better target priority groups in ITN distribution campaigns.
Recommendations to tailor behavior change communication messages.

Visual Highlights

Regional variation in Guinea of A household ITN ownership; B proportion of the population with access to an ITN; C ITN usage; and D ITN usage among those with access.
