This systematic review and meta-analysis aimed to assess the robustness of designs and tools used in NSBCC interventions and establish their effectiveness. EBSCOhost as an umbrella database including Medline (Ovid) and CINAHL, EMBASE and ProQUEST databases were searched for peer-reviewed articles from January 1960 to October 2018. Additional sources were searched to identify all relevant studies including grey literature. Studies’ biases were assessed according to Cochrane handbook. Pooled estimate of effectiveness of interventions on infant and young child feeding (IYCF) practices and child nutritional status with 95% confidence intervals were measured using random-effects models. Eighty studies were included in this review: Fifty-one (64%) were cluster randomised trials (RCTs), 13 (16%) were RCTs and 16 (20%) quasi-experimental. Of the included studies, 22 (27%) measured early initiation of breastfeeding, 38 (47%) measured exclusive breastfeeding, 29 (36%) measured minimum dietary diversity, 21 (26%) measured minimum meal frequency, 26 (32%) measured HAZ, 23 (29%) measured WHZ, 27 (34%) measured WAZ, 20 (25%) measured stunting, 14 (17%) measured wasting, and 11 (14%) measured underweight. The overall intervention’s effect was significant for EBF (OR = 1.73; 95% CI: 1.35–2.11, p < 0.001), HAZ (Standardized Mean Differences, SMD = 0.19; 95% CI: 0.17–0.21; p < 0.001), WHZ (SMD = 0.02; 95% CI: 0.004 to 0.04; p < 0.001), and WAZ (SMD = 0.04; 95% CI: 0.02 to 0.06; p < 0.001). Evidence shows the effectiveness of NSBCC in improving EBF and child anthropometric outcomes. Further research should test the impact on child nutritional status with clearly specified and detailed NSBCC interventions.
It is necessary to significantly accelerate the progress for optimal young child feeding practices in order to attain global nutrition goals and targets. Innovative and compelling communication approaches should be explored and tested to change social behaviours towards nutrition. A concept promoted in Nepal known as Poshan Nanglo (Nutrition Tray), is an interactive demonstration of locally available and nutritiously diverse foods. Using qualitative methodology, this study adopts the phenomenology method to understand preferences and perceptions of Poshan Nanglo among mothers of young children. A total of 305 mothers of children aged 6 to 23 months were interviewed from September 2019 to January 2020. 90%preferred Poshan Nanglo over printed materials. Three themes emerged: a simple and an easy way to learn, the use of real foods help to understand better and it is a practical approach. Thus mothers preferred and appreciated Poshan Nanglo to improve their understanding of good child feeding practices. These mothers also showed improvements in relating the importance of locally available nutritious foods for optimal dietary diversity. Approaching behaviour change should be informed and shaped by the beneficiaries’ interests and preferences. As a simple and sustainable approach in communicating about dietary diversity and good nutrition, Poshan Nanglo has wide relevance and potential.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
