Effect of Decreased Marketing on Micronutrient Sprinkles Distribution in Western Kenya

Abstract

Background In 2007, CDC partnered with local Kenyan institutions to evaluate the effectiveness of community-based distribution of micronutrient Sprinkles among preschool children. Data from the first year of the study demonstrated high Sprinkles coverage and acceptability. In 2009, routine marketing and household monitoring ended as part of the study, but Sprinkles sales continued. Objective To evaluate the sustainability of market-based community distribution of Sprinkles. Methods In 2010, we conducted a cross-sectional survey of 862 children aged 6–35 months randomly selected from 60 study villages. Frequencies were calculated, and logistic regression evaluated associations between exposures and Sprinkles use. Results An average of 18.5% of households reported purchasing Sprinkles in the last 2 weeks compared to 33% in year 1. Average intake was 0.6 sachets/week, compared to 0.9 sachets/week in year 1. Factors associated with Sprinkles use included attendance at trainings or launches and receipt of promotional items including calendars, cups, and t-shirts during year 1 (p < 0.05). Neither socioeconomic status nor maternal education was associated with Sprinkles use. Conclusions Sprinkles sales were reduced after stopping household monitoring and reducing marketing activities. Promotion and ongoing monitoring of Sprinkles should be an integral component of a scaled-up program.
