Strategy researched

Nutrition social behaviour change communication (NSBCC) interventions (interpersonal counselling, use of media (IEC materials, mass media, phone messaging), community mobilisation)

Impact achieved

Overall, almost two-thirds of the studies reported a significant positive effect on early initiation of breastfeeding (EIBF). Of the 38 cluster RCTs studies reporting on exclusive breastfeeding (EBF), 33 (87%) found a statistically significant positive impact. All studies across all study designs: 6 out of 13 (46%) RCTs measured or reported on EBF and of these, 5 (83%) found a significant positive effect. Twenty-two out of the 51 (43%) cluster randomised trials measured and reported on EBF and of these, 20 (91%) reported a statistically significant positive impact.

Countries of study

38 studies from Asia, 35 from Africa, 6 from South America, and 1 from Europe

Research methodology

Systematic review with 80 studies (51 cluster RCTs and 13 RCTs)

The effectiveness of interventions on nutrition social behaviour change communication in improving child nutritional status within the first 1000 days: Evidence from a systematic review and meta-analysis

Excerpt from Abstract

"The overall intervention's effect was significant for exclusive breastfeeding (EBF) (odds ratio = 1.73; 95% confidence interval [CI]: 1.35-2.11, p < 0.001), HAZ [height for age z-scores] (standardized mean differences [SMD] = 0.19; 95% CI: 0.17-0.21; p < 0.001), WHZ [weight for height z-scores] (SMD = 0.02; 95% CI: 0.004-0.04; p < 0.001), and WAZ [weight for age z-scores] (SMD = 0.04; 95% CI: 0.02–0.06; p < 0.001). Evidence shows the effectiveness of NSBCC in improving EBF and child anthropometric outcomes."

Your Priorities, Opportunities and Challenges? Complete the SURVEY

Why the focus on direct impact data?

A common challenge from policy makers, funders, community members, people directly experiencing development issues, and governments is: Demonstrate your Impact. Prove that what you are doing works. The high quality, highly credible data presented on the cards below is designed to help you answer that question for your social change, behaviour change, community engagement, communication and media for development, strategy formulation, policy engagement and funding initiatives. At this link filter the research data to your specific interests and priorities

Why a playing cards design?

There is a physical pack of cards with this data (to get a copy please request through the comment form for any card). The card approach allows for easy identification and selection of relevant direct impact data in any context. For example if talking with a donor and you need to identify proof of impact say "take a look at the 7 of Hearts". Quick access can be provided to high-quality data for many areas of your work – funding, planning, policy, advocacy, community dialogue, training, partner engagement, and more. A card deck is also engaging, easy to use and share, a conversation starter, and a resource - and they are fun and different. So we kept that design for the online images as it can serve similar purposes.
