Study design: The study was designed to review the secondary nutrition program performance data and conduct a cross-sectional study using both quantitative and qualitative data collection to gain deep insight into the impact of the SBC activities on changing the behavior of the target population. Place and Duration of Study: Data was collected in the Rohingya refugee camps, where the forcefully displaced Myanmar nationals were staying and getting nutrition support in Ukhiya of Cox’s Bazar district of Bangladesh. The main data collection took place from 10th October 2024 to 30th October for quantitative data and from 1st November to 6th November 2024 for qualitative data. Methodology: A household survey was conducted to collect quantitative data from the project beneficiaries. This survey was tailored to gather relevant indicators and assess the effectiveness of the interventions. Quantitative data were collected from the beneficiaries through household surveys. We included 250 pregnant and lactating women (PLW) and 250 caregivers of 0-59-month-old children (28 males and 459 females). Qualitative data were obtained through Focus Group Discussions (FGDs-6; 8-10 females per FGD) and Key Informant Interviews (KIIs-5; MtMSG members, nutrition and health staff, and participants from cooking demonstrations). Results: A complete package of the SBC approach is essential to breaking the social stigma and barrier targeting the audience through different methods; for example, to improve the Infants and Young Child Feeding (IYCF) indicators by providing IYCF messages through health and nutrition education, group messaging at IYCF corner, community sensitization, meetings, and workshops, mother-to-mother support groups, IYCF counseling from IYCF corner at nutrition facilities as well as health facilities. Complementary feeding cooking demonstration for hands-on learning can change the negative behavior of the targeted audience in a positive direction. In this study, we found that 94.3% of mothers changed one of the negative behaviors related to IYCF in a positive direction. All mothers knew the importance of exclusive breastfeeding, and 83.7% of mothers practiced it properly, which is higher than the exclusive breastfeeding rate of 62.3% (IYCF Survey 2022 by UNICEF-ACF) (11). 68.4% of mothers ensured the minimum dietary diversity of complementary feeding for children 6-23 months, 28.2% in the last IYCF survey by UNICEF-ACF 2022, which came from the complete SBC approach to IYCF practices. Conclusion: This comprehensive study of secondary data review and qualitative findings with validation through the quantitative survey finds that a comprehensive nutrition activity engaging the target population in the SBC activities changes the social stigma and barrier. All mothers who attended the study expressed proper knowledge of IYCF and also emphasized their physical and mental health to ensure proper IYCF practices for children 0-23 months such as exclusive breastfeeding for the first six months, starting complementary feeding after six months, and ensuring the minimum dietary diversity to ensure proper nutrition of the young children. This group of mothers can work and support other mothers in the best practices of IYCF and break the social stigma and barriers of IYCF practices.]]> Dr. Taslima Arzu, Md. Ariful Kabir Sujan, S.M.
