简要总结
This project will examine the impact of an infant and young child feeding (IYCF) voice messaging intervention delivered to mothers and fathers in Senegal on the consumption of a minimum acceptable diet and anemia prevalence in their children.
详细描述
This is a cluster-randomized control trial (cRCT) conducted with 488 mother, father, and child triads in 104 villages in three regions in Senegal: Thies, Diourbel and Fatick. Mothers and fathers in the experimental group will receive 16 voice and text messages over the course of 16 weeks. One voice and 1 text message with the same content will be sent per week over the 16 week period. We will include eight scripted messages which have previously been piloted. We will also include eight unscripted messages from positive deviants from communities similar to our study population that were included in our pilot study. A text message with the same content as the voice message will be sent to each triad mother and father to increase the reach of the intervention. We will conduct baseline and endline assessments of infant and young child feeding practices in both the experimental and control groups. Primary outcomes will include the prevalence of anemia and minimum acceptable diet in children. Minimum acceptable diet is an indicator of dietary diversity and a proxy for nutrient adequacy. Secondary outcomes include the frequency of consuming key foods targeted in the intervention over the previous 7 days and infant and young child feeding indicators of complementary feeding of the child. In addition, infant and young child feeding knowledge, beliefs, and norms (of mothers and fathers in triads) and intentions (of mothers in triads) will be included as secondary outcomes.

结局指标
主要结局
Number of Children Who Consume a Minimum Acceptable Diet
时间窗: At study completion, an average of 4 months after baseline
The minimum acceptable diet indicator will be used to assess diet quality in children. A list-based recall will be used to assess dietary intake over the previous day. The 24-hour recall will be used to calculate minimum dietary diversity (MDD) (consuming 5 or more of 8 food groups (breast milk; grains, roots, tubers and plantains; pulses (beans, peas, lentils), nuts and seeds; dairy products (milk, infant formula, yogurt, cheese); flesh foods (meat, fish, poultry, organ meats); eggs; vitamin A rich fruits and vegetables; other fruit and vegetables) and minimum meal frequency (MMF) (2x/day for breastfed infants 6-8 months; 3x/day for breastfed children 9-23 months; 4x/day for non-breastfed children 6-23 months). Children who meet the thresholds for both MDD and MMF are defined as consuming a MAD, based on the WHO/UNICEF IYCF indicator.
Anemia Prevalence of Children
时间窗: At study completion, an average of 4 months after baseline
Hemocue Hb301 machines to measure hemoglobin levels in children in order to determine anemia prevalence using the WHO cut-offs: mild 10 ≤ hb \< 11 g/dl; moderate 7 ≤ hb \< 10 d/dl and severe hb \< 7 g/dl. A finger prick will be used to obtain a drop of capillary blood that is placed on a cuvette and inserted in the Hemocue machine to obtain an on-the-spot assessment of hemoglobin levels.
Change in Percentage of Children Consuming a Minimum Acceptable Diet Between Baseline and Endline
时间窗: Between baseline and study completion, an average of 4 months after baseline
The change in percentage of children meeting the minimum acceptable diet indicator between baseline and endline will be used to assess diet quality in children. A list-based recall will be used to assess dietary intake over the previous day. The 24-hour recall will be used to calculate minimum dietary diversity (MDD) (consuming 5 or more of 8 food groups (breast milk; grains, roots, tubers and plantains; pulses (beans, peas, lentils), nuts and seeds; dairy products (milk, infant formula, yogurt, cheese); flesh foods (meat, fish, poultry, organ meats); eggs; vitamin A rich fruits and vegetables; other fruit and vegetables) and minimum meal frequency (MMF) (2x/day for breastfed infants 6-8 months; 3x/day for breastfed children 9-23 months; 4x/day for non-breastfed children 6-23 months). Children who meet the thresholds for both MDD and MMF are defined as consuming a MAD, based on the WHO/UNICEF IYCF indicator.
Change in Percentage of Children With Anemia Between Baseline and Endline
时间窗: Between baseline and study completion, an average of 4 months after baseline
We will use Hemocue Hb301 machines to measure hemoglobin levels in children in order to determine anemia prevalence using the WHO cut-offs: mild 10 ≤ hb \< 11 g/dl; moderate 7 ≤ hb \< 10 d/dl and severe hb \< 7 g/dl. A finger prick will be used to obtain a drop of capillary blood that is placed on a cuvette and inserted in the Hemocue machine to obtain an on-the-spot assessment of hemoglobin levels. The change in child anemia prevalence between baseline and endline will be examined (calculated as endline-baseline/baseline\*100).
