Effects of community-based educational video interventions on nutrition, health and utilisation of health services in low- and middle-income countries: Systematic review and meta-analysis
Summary
This systematic review and meta-analysis evaluate the effects of video-based educational interventions on nutrition, health, and health service utilization in low- and middle-income countries (LMICs). It demonstrates that video interventions improve key outcomes such as maternal knowledge of newborn care, colostrum feeding practices, continued breastfeeding, and the intention to use family planning. However, some areas, such as exclusive breastfeeding and dietary diversity, showed limited or no improvement. Video-based approaches were found to be both feasible and acceptable among target populations, enhancing behavior change communication. Nonetheless, the study underscores challenges like sustainability, variability in intervention design, and the need for stronger research designs to assess long-term impacts.
Abstract
his systematic review and meta-analysis examine the impact of video-based educational interventions on nutrition, health, and health service utilization in low- and middle-income countries (LMICs). The analysis reveals that video interventions significantly improve maternal knowledge of newborn care, colostrum feeding practices, continued breastfeeding, and the intention to use family planning. Despite these gains, limited effects were observed in areas such as exclusive breastfeeding and dietary diversity. Video-based education emerged as a feasible and culturally acceptable tool for behavior change communication in LMICs. However, challenges related to intervention sustainability, design variability, and the assessment of long-term outcomes highlight the need for more robust research methodologies. The findings support video-based interventions as an effective strategy to enhance health and nutrition behaviors, with recommendations for tailored implementation in diverse settings.
