Summary
Understanding insecticide-treated nets (ITNs) purchase determinants is crucial for malaria prevention. Findings show stated willingness to pay predicts actual purchases, highlighting the need for accessible distribution and equitable financing for ITNs programs.
Area of Science:
- Public Health
- Malaria Control
- Health Economics
Background:
- Insecticide-treated nets (ITNs) are a key tool for malaria prevention.
- Understanding factors influencing ITN adoption is vital for program success.
Purpose of the Study:
- To identify determinants of insecticide-treated net (ITN) purchase.
- To explore policy implications for ITN programs.
Main Methods:
- Two surveys were conducted in three villages, assessing stated willingness to pay (WTP) and actual ITN purchases.
- Contingent valuation methods (bidding game, binary with follow-up, structured haggling) and logistic regression were employed.
- ITNs were sold at a fixed price (350 Naira).
Main Results:
- Stated WTP positively correlated with actual ITN purchases (p < 0.01).
- Lower socioeconomic groups were less likely to purchase ITNs.
- Households with recent malaria and higher stated WTP were more likely to purchase; increased distance to sales points reduced purchases (p < 0.05).
Conclusions:
- Stated WTP is a reliable predictor of actual ITN purchase behavior.
- Distribution strategies reducing time and travel costs are essential for increasing ITN coverage.
- Financing mechanisms must ensure equitable access for vulnerable populations and those at high malaria risk.
