Impact of Food-to-Food Fortified Cereal Products on Diet Quality in Eldoret, Kenya

Basic design:

Participants will be approached/recruited by research assistants on the ground at designated local markets. Potential participants will be consented if they agree to join the study at the time of recruitment. While attendance is not required by participants, product demonstrations will be conducted at the study sites, similar to a grocery store demonstration, to show how the instant flour is reconstituted. At the same time, consumers who are attending the demonstrations may be asked if they would participate in the study. Research assistants will read the consent form to the participants and ensure they understand it. Purdue investigator(s) (one or more - Torres-Aguilar, Rendall, Hamaker) will be present in Eldoret at all study phases involving consenting and data collection.

Products will be produced, distributed on a weekly basis to sites. The investigators plan on introducing the "new" product to consumers at random at in-store displays at individual locations for 2 weeks, and then continue to promote (advertise) and sell the placed product for a period of 8 weeks. The following schedules are proposed:

Weeks 1-2: Product demonstrations and sampling for consumers Weeks 3-5: Product sold at below market cost of other cereal flour products (as part of active promotion) Weeks 6-10: At one half of the locations, product sold at parity to other cereal products (with advertising but no additional promotion, i.e. discounts).

Data to be collected both from store managers and individual consumers. Enumerators will be trained and placed at each sales' location in the morning and evening to coincide with peak shopping times. They will be tasked with collecting a random sample of consumers who are purchasing cereals (1,200 total over 10 weeks). In this sample, both purchasers and non-purchasers of the FtFF fortified products will be identified and consented. Phone numbers will be collected and a follow up appointment/interview scheduled with half of them (600).

Enumerators will also coordinate the collection of data from point of sale managers:

• Total volume/units of FtFF fortified product sold
• Total volume/units cereal products sold
• Total value of FtFF fortified product sold
• TotaI value of cereal product sold
• Product comments from consumers (include any returns or complaints)
• Number of repeat purchasers

Follow up interviews with consumers will be conducted at a private location close to the centralized market sites or points of original purchase within 2 weeks. This is to enable follow up without inconveniencing participant.
