2 Country context Population: 25 million/per capita income $240 Under 5 mortality is 61/1,000 live births* Diarrhea: major cause of child mortality –4 th for children < 5 years –2 nd for children 12-59 months * Source: Nepal Demographic and Health Survey, 2006 66% of diarrhea cases treated 27% treated by health provider –61% used Oral Rehydration Solution/Therapy (ORS/ORT) –68% used pills/syrups –0.6% used Zinc

3 Social marketing campaign – June to October 2009 Interventions: Mass media - 5 languages 3418 TV ads; 14,622 radio ads Promotion through health providers 3009 providers trained/ 2500+ job aids 8000 Point of purchase materials Objective: Increase availability and use of Baby Zinc to reduce severity of diarrhea in children under 5, while maintaining use of ORS to avoid dehydration. Campaign promoted “zinc with ORS”. Community-level activities 5030 mothers of children <5 reached Private sector increased supply and number of brands of zinc

4 Evaluation methodology Post campaign: random household survey–Dec 2009 –knowledge, attitudes and practices (KAP) –2300 households in the 27 program districts Compared to pre-intervention study – Sept 2008 –Same methodology and sample size; same research firm –Compared pre-post data only in 13 overlapping districts Oversampled in post to increase number of children with diarrhea in last 2 weeks (less than 7% of random sample), to maximize efficiency and minimize costs Also analyzed post data by comparing: –zinc usage behavior by exposure to campaign –attitudes toward zinc by recent use of zinc for diarrhea

5 Background Characteristics Background characteristics of caregivers in the 2008 and 2009 studies are similar

6 Percentage of children with diarrhea in preceding two weeks No difference in diarrhea prevalence was observed

7 Treatment practices among caregivers with children having diarrhea in last 2 weeks Total use of zinc as well as zinc with Oral Rehydration Solution (ORS) increased; however, total use of ORS decreased (all at p<0.05)

8 Impact of campaign on knowledge and usage – post only Almost all (96%) of total respondents reported exposure to a baby zinc message, with 84% reporting exposure to specific campaign messages n=2070

9 Impact of media exposure on zinc Usage Exposure to campaign messages had a significant (p<0.05) impact on zinc usage and knowledge, among those with <5 child with diarrhea in prior 2 weeks. Correct use definition: “knows that a child should be given zinc continuously for 10 days”

10 Those who used Baby Zinc to treat diarrhea are significantly more positive about its effectiveness Among those treating diarrhea in last 2 weeks with zinc (n=45) Among those NOT treating diarrhea in last two weeks with zinc (n=134) Baby Zinc is effective for treating diarrhea 96%23% Baby Zinc reduces the duration of diarrhea 87%18% Baby Zinc reduces the risk of new diarrheal episode in the following 2-3 months 67%11% Baby Zinc is the most appropriate treatment for diarrhea 91%25% Baby Zinc with ORS/ORT should be used for every type of diarrhea 73%15% Baby zinc reduces the risk of dehydration in children 69%11% Baby zinc helps strengthen the immune system 64%13% * All of the beliefs are significantly higher (p<0.05) for zinc users than for non-users; Respondents from all 27 districts

11 Almost half of the zinc used was acquired from private pharmacies, a significant increase from pre-campaign

12 Among those treating diarrhea in last 2 weeks with zinc (n=45) Among those NOT treating diarrhea in last two weeks with zinc (n=134) Availability Shops nearby always have baby zinc 87%23% There is a place nearby where I can get baby zinc when my child needs it 93%23% Baby zinc is available within walking distance of my home 93%25% Affordability I am willing to pay the current price for Baby zinc 60%13% Baby Zinc users are significantly more likely than non-users to believe the product is easily available and to be willing to pay the current price * All of the beliefs are significantly higher (p<0.05) for zinc users than for non-users; Respondents from all 27 districts

13 Summary of program results Zinc usage among caregivers of children under 5 years increased in Nepal –Could decline in other pills/syrups use be due to zinc increase? Caregivers exposed to campaign messages are more likely to use zinc (and zinc with ORS) than those not exposed Baby Zinc users are significantly more positive than non-users about Baby Zinc’s –Effectiveness –Availability –Affordability Private pharmacies – main source of zinc supply

14 Summary Evaluation Methodology A well-designed post-implementation survey can be used as an endline o If a pre-implementation study can be found, the districts overlap, and the methodology can be duplicated Oversampling of households with children <5 with diarrhea in last 2 weeks was effective at maximizing efficiency o Permitted determination of significant differences between pre and post, user and non-user, and exposed vs. not exposed, at low cost These study results indicate that it can be difficult to maintain high levels of a current practice (ORS) when promoting a new one (zinc) for the same illness/symptom
