Abstract

Background: Achieving appropriate feeding for infants and young children continues to be a struggle. These impediments are not only due to limited food availability but also inadequate knowledge, unfavorable attitudes, and low self-efficacy. A positive deviant approach (PDA) addressing positive and possible solutions inherent in a community focusing on problems is applied in Africa and particularly to Ethiopia. Therefore, this trial is aimed at evaluating the effectiveness of PDA in improving mothers' nutritional knowledge, attitudes, self-efficacy, and children's nutritional status.

Method: This was a cluster randomized control trial in which 516 mothers were randomly assigned to either an intervention or control group after collecting baseline data. The trial participants in the intervention cluster received a positive deviant intervention for 6 months, whereas those in the control group received only the usual care. Trained positive deviant mothers (PDM) delivered the intervention. A pretested, structured, interviewer-administered questionnaire was used for data collection. Generalized estimating equation regression analysis adjusted for baseline covariates and clustering was used to test the intervention effect.

Result: The results showed that PDA improved breastfeeding outcomes in the intervention groups compared to their counterparts. A mean difference (MD) of breastfeeding (BF) knowledge (MD = 6.47; 95% CI: 6.45-6.49), BF attitude (MD = 12.68; 95% CI: 11.96-13.40), and BF self-efficacy (MD = 3.13; 95% CI: 3.05-3.21) was observed favoring the intervention. The intervention group showed better improvement in complementary feeding (CF) knowledge, attitude, and self-efficacy among mothers compared to the control group. A mean difference in CF knowledge (MD = 4.53, 95% CI: 4.31-4.75), CF attitude (MD = 9.14, 95% CI: 8.52-9.75), and CF self-efficacy (MD = 11.64, 95% CI: 11.16-12.12) were observed favoring the intervention. At the end of the 6-month follow-up, children in the intervention group showed a lower prevalence of underweight (18.23%) (95% CI: 4.55, 22.54%; p = 0.004) compared with the control group.

Conclusion: PDA was effective in improving mothers' nutritional knowledge, attitude, and self-efficacy and reducing children's underweight in the intervention area.Clinical trial registration:ClinicalTrials.gov, identifier PACTR202108880303760.
