Assessing ITN textile preferences: A comparative study of polyethylene and polyester nets across different settings in Burkina Faso

---

Résumé

Insecticide-treated nets (ITNs) are crucial for preventing malaria and other vector-
borne diseases, effectively reducing transmission and mortality rates. However, their
uptake remains low, influenced by textile preferences, with polyester nets being
favored for comfort, despite their shorter lifespan compared to other materials. A
study in Burkina Faso aimed to understand community preferences for ITN fabrics
across different environmental contexts to improve malaria control strategies. Using a
mixed-methods approach, the study surveyed and interviewed urban and rural com
munities in three climatic zones of Burkina Faso to identify socio-economic, environ
mental, and cultural factors shaping ITN material preferences. The study found that
95.2% (95% CI: 94.6–95.7) of participants had a preference for a specific ITN fabric,
with 93% (95% CI: 92.3-93.6) favoring polyester over polyethylene, citing superior
comfort, breathability, and protection. Regional differences emerged, with rural areas
and the Humid savannah-Sahelian zone showing a stronger preference for poly
ester nets, especially in larger sizes. The study recommended that malaria control
programs prioritize polyester-based nets, offer larger sizes for rural populations, use
smaller mesh sizes, and adopt rectangular designs to improve coverage and comfort.
Urban populations emphasized comfort and efficacy, while rural areas focused more
on durability and size. Factors like ease of maintenance, comfort, and local climate
were significant in shaping preferences. The study concluded that tailoring ITN
distribution strategies to regional needs such as adjusting net size and mesh could
improve malaria control efforts. These insights can guide the optimization of malaria
prevention programs, enhancing their effectiveness and long-term sustainability in
diverse settings.
