Effectiveness of an integrated multilevel early child development intervention on caregiver knowledge and behavior: a quasi-experimental evaluation of the Malezi program in Tanzania.

BACKGROUND: The quality of caregiving and the parent-child relationship is critical for early child development (ECD) and has been shown to be modifiable. This study evaluated an ECD project in Tanzania, assessing the effectiveness of radio messaging (RM) alone and a combined radio messaging/video job aids/ECD (RMV-ECD) intervention. METHODS: This two-arm pre-post evaluation study enrolled a cohort of caregivers of children 0-24 months in four districts of Tabora region, following them for 9 months. ECD radio messages were broadcast on popular stations at least 10 times/day reaching all study districts. In two districts, community health workers (CHW), trained in UNICEF's Care for Child Development package, used ECD videos in home- and facility-based sessions with caregivers. We used McNemar's testing (pre-post pairs) within intervention group to describe how the intervention was associated with change in five outcomes: ECD knowledge, early stimulation, father engagement, responsive care, and environment safety. Logistic regression was used to describe the relative benefits of the combined intervention package (RMV-ECD) compared to radio messaging (RM). RESULTS: In the RMV-ECD arm, all outcomes at endline except environment safety significantly improved after the intervention with the largest change seen in ECD knowledge (35.8% increase, p < .0001) and the smallest in father engagement (6.7%, p = .015). In the RM arm, ECD knowledge (5.7%, p = .031) and environment safety (18.1%, p = <.0001) improved. High measures of parenting stress were associated with lower likelihood of having good ECD knowledge (AOR 0.50, 95%CI: 0.35, 0.71), father engagement (AOR 0.72, 95%CI: 0.52, 0.99) and responsive care (AOR 0.31, 95%CI: 0.18, 0.54). CONCLUSIONS: An intervention that includes mass media, educational video content and CHWs who counsel caregivers in their homes and health facilities was associated with significant improvements in ECD parenting knowledge and behaviors but a relationship with responsive care could not be established. The less costly mass media-only intervention was associated with improved parenting knowledge and household environment safety. Parenting interventions targeting young children could be improved by incorporating more messaging and caregiver coaching in managing parental stress.

A Qualitative Exploration on Perceived Socio-Cultural Factors Contributing to Undernutrition Among Under-Fives in the Southern Highlands of Tanzania.

Objective: Under nutrition especially among under-fives is a major public health challenge in Tanzania. However, the contribution of cultural practices to child under nutrition is often overlooked. This study aimed to explore the perceived socio-cultural factors contributing to the persisting under nutrition among under-fives in Tanzania. Methods: The study applied focus group discussion (FDGs) with forty practitioners to examine the sociocultural factors contributing to under nutrition during early childhood. The study participants were purposively selected and thematic analysis was used to identify themes within the data. Results: This study revealed that, under nutrition for under-fives is caused by a number of socio-cultural factors including existence of gender inequality related to dietary practices and qualities, women's excessive workload, patriarchy social-norm, excessive alcohol use and cultural taboos prohibiting women and girls from eating certain types of nutrient dense foods. Conclusion: The study highlights the multiplicity of factors including socio-cultural perspectives contributing to under nutrition among under-fives, and calls for a concerted efforts in developing and implementing issue-specific and culturally sensitive strategies towards elimination of child under nutrition.

Improvement of community health worker counseling skills through early childhood development (ECD) videos, supervision and mentorship: A mixed methods pre-post evaluation from Tanzania.

BACKGROUND: Community health workers (CHWs) play significant roles in improving health practices in under- resourced communities. This study evaluated an early childhood development (ECD) project in Tanzania assessing the effect of mobile video use, supervision and mentorship to improve quality of CHW counseling skills. METHODS: CHWs participating in the Malezi Project in Tabora Region were enrolled in a mixed methods pre-post evaluation. CHWs previously trained in UNICEF's Care for Child Development package were further trained in counselling caregivers on nurturing care and father engagement using videos. Health providers were trained to provide ECD-focused supervision/mentorship of CHWs in facilities and during home visits. At baseline and endline, CHWs completed interviews and trained study staff observed and scored CHW counseling sessions using a structured checklist which were reduced into six dimensions through principal component analysis: introduce, educate, ask, plan/problem solve, interact/encourage, and responsive care. Twenty-five in-depth interviews were completed with caregivers and four focus group discussions with CHWs were conducted. RESULTS: Almost all (n = 107; 95%) 119 enrolled CHWs completed the expected eight observations (n = 471 baseline; n = 453 endline). At endline, more CHWs reported having one-on-one meetings with their supervisors (51% increasing to 75%; p < .0002) and that supervisors accompanied them to households for mentoring (60% increasing to 89%; p < .0001). We observed a shift in CHW counselling skills in clinic and home sessions. Scores in the categories of introduce, plan/problem solve, and interact/encourage significantly improved between baseline and endline; scores for ask and educate remained unchanged or decreased at both timepoints. Two-thirds of caregivers interviewed reported that father's involvement with their child increased due to CHW visits. Male participation increased in home observation sessions from 5.6% at baseline to 17.6% at endline (p < .0001). CONCLUSION: Use of videos, supervision, and mentorship were associated with CHW performance improvements in providing nurturing care counselling and in father engagement, especially in home settings.
