Anambra State Post-Campaign Net Tracking Survey

Impact on actual behaviour
Anambra LLIN campaign evaluation
The two variables “intention of household to use nets every or most nights” and “household
discussed net use in family”, both positively associated with exposure to messages on net use,
were then used to explore the question whether these had impact on the actual behaviour of
the household regarding hanging and use of nets. Using only households with any nets (N=792)
multivariate regression analysis was applied adjusting for any potential confounder or effect
modifier and resulting Odds-Ratios (OR) of the two variables of interest are shown in Figure 15.
Both, discussing net use and expressed intention to use were significantly associated with
hanging or using the nets with little difference between any or all nets hung or used. The only
difference was that for net use the intention had a somewhat stronger association than
discussion although not statistically significantly. There was no interaction between discussion
and intention, i.e. having discussed and intention did not increase the chances of hanging or
using the nets. There also was a dose-response relationship with the number of net messages
recalled for the hanging of nets suggesting that the odds of hanging any net increased by 39%
with each additional message recalled (p=0.014). This was not the case for the use of nets,
however, use was associated with recalling any message specifically referring to net use (OR
1.67; 95%CI 1.00 to 2.79, p=0.05). None of the background characteristics nor educational level
of the head of household had any association with the outcome variables.
