Description détaillée
The Global Alliance for Improved Nutrition (GAIN) seeks to improve dietary quality among children under-five years of age in Kaduna by increasing the demand for eggs through above-the-line and below-the-line behavior change interventions incorporating mass media, social media, and point-of-sale (POS) marketing. Above-the-line (ATL) interventions include television, radio, celebrity ambassadors and out-of-home (OOH) advertising (e.g., billboards). Below-the-line interventions (BTL) include interpersonal communication (IPC) activation, trade promotions, point-of-sale materials, food demonstrations and giveaways and door-to-door activation.
GAIN conducted a quasi-experimental longitudinal study of a demand creation campaign, using ATL and BTL interventions, among families of children 6-59 months of age to determine the impact on egg consumption among children and egg acquisition. Kaduna state was chosen as the intervention arm, and Kano state as the comparison arm. Within Kaduna state, the Kaduna North and Chikun local government areas (LGAs) were selected to receive ATL and BTL demand creation interventions. The comparison state, Kano, received no demand creation campaign.
The principal comparison for measuring the effect of demand creation interventions will be across states, comparing the combined effects of ATL and BTL interventions with the comparison areas which received no intervention.
Investigators also set out to determine the impact of this intervention on mediating outcomes in the hypothesized causal framework. Proximal mediators included caregivers' attitudes and beliefs toward eggs and willingness to pay for eggs.

Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Change in the consumption of any eggs by children 6-59 months from baseline to endline in the two study arms
Délai: From baseline to 14 months
|
Change in the consumption of one or more eggs by children 6-59 months of age from baseline to endline
|
From baseline to 14 months
|
|
Change in caregivers' (of children 6-59 months) attitudes, beliefs, and knowledge of eggs from baseline to endline
Délai: From baseline to 14 months
|
Change in the mean factor score created from Likert scales of attitudes (attitudes scale, higher score reflects better attitudes towards eggs), perceived benefits (benefits scale, higher score reflects better perceived benefits towards eggs), norms (norms scale, higher score reflects better norms towards eggs), self-efficacy (self-efficacy scale, higher score reflects better self-efficacy), and intention towards eggs (intent to feed eggs to child, higher score reflects more intent to feed eggs) from baseline to endline between the two study arms; change will be examined for a meta factor score combining all scales and each scale separately.

From baseline to 14 months
|
|
Change in caregivers' willingness to pay for eggs from baseline to endline
Délai: From baseline to 14 months
|
Change in willingness to pay for eggs, using for example the change in mean maximum price that caregivers would be willing to pay for eggs from baseline to endline between the two study arms.
