Positive Deviance/Hearth (PDH) is an internationally recognized nutrition rehabilitation program. However, nutritional improvements are inconsistent across contexts. It is unclear if variations are due to differences in program design, implementation, utilization, or other contextual factors. Furthermore, few PDH programs have addressed the high time and work burdens of caregivers and volunteers. To address this, the study integrated interactive voice calling (IVC) with PDH. A program impact pathway (PIP) analysis was used to evaluate the secondary outcomes of facilitators, barriers, and contextual factors that influenced the design, implementation, and utilization of a Positive Deviance/Hearth-Interactive Voice Calling program to improve the nutritional status of children in Cambodia. A PIP analysis was done on data collected through in-depth interviews with caregivers (n = 32), key informant interviews with volunteers (n = 16) and project staff (n = 3), and surveys of project staff (n = 5). In the design phase, facilitators included quality training, technical support and design tools, community mobilization, and linkage to existing health services. Barriers included poor community mobilization. For the implementation phase, facilitators were good volunteer knowledge, follow-up tools and guidance, supervision, and spot checks of volunteers. Barriers were lack of time and overworked older caregivers. For the utilization phase, facilitators included family and volunteer support and access to phones, whereas barriers were lack of support, time, and financial resources; low levels of education and old age of caregivers; and inconsistent phone use. Contextual factors included food insecurity and increased childcare responsibilities of grandmothers due to migration of mothers. The PIP analysis identified facilitators, barriers, and contextual factors that may affect the design, intervention, and utilization of IVC interventions for health and nutrition behavior change and elements to consider when designing and implementing them. When implementing child nutrition programs in Cambodia, supporting interventions addressing mental health and time and resource constraints of elderly caregivers should also be included. This trial was registered at clinicaltrials.gov as NCT03399058.

Suboptimal infant and young child feeding (IYCF) practices contribute to child undernutrition. Sierra Leone Demographic and Health Survey data show that IYCF practices remain poor despite modest improvements. Recent studies have identified the role of grandmothers as critical to child nutrition; however, in Sierra Leone to date, the potential for grandmothers to influence IYCF practices has not been investigated. We examined how an innovative grandmother-inclusive approach (GMIA) can be used to address suboptimal IYCF practices. Using a quasi-experimental design, we compared IYCF beliefs and practices between GMIA intervention communities (receiving monthly dialogue sessions on nutrition, quarterly community praise sessions, and intergenerational forums) and comparison communities (receiving standard nutrition education) in Bum chiefdom from 2013 and 2016. The quantitative endline survey targeted 101 pregnant women, 291 women with children aged t tests and χ² tests to examine differences between intervention and comparison communities at endline. Multivariate regression was used to determine the intervention's effect on IYCF outcomes of interest. Awareness of and participation in the GMIA was high among mothers and grandmothers in intervention communities. The percentage of infants and young children aged 0–23 mo (n = 291) exclusively breastfed during the first week of life was significantly higher in the intervention group (90.2% compared with 79.4%, P = 0.01). Among infants aged 6–23 mo (n = 219), the percentage achieving minimum dietary diversity and minimum acceptable diet was significantly higher in the intervention group (77.2% compared with 51.8%, P < 0.001; and 53.8% compared with 22.6%, P < 0.001, respectively). Differences in percentages achieving minimum meal frequency (MMF) were only significant for infants aged 9–23 mo, with the intervention group achieving a higher MMF (54.6% compared with 36.9%, P = 0.02). Results suggest that a GMIA that recognizes grandmothers’ roles and strengthens their knowledge can contribute to improved IYCF practices.

Despite the recent international focus on maternal and child nutrition, little attention is paid to nutrition capacity development. Although infant feeding counselling by health workers increases caregivers’ knowledge, and improves breastfeeding, complementary feeding, and children’s linear growth, most of the counselling in sub-Saharan Africa is primarily conducted by nurses or volunteers, and little is done to develop capacity for nutrition at the professional, organizational, or systemic levels. The Cameroon Baptist Convention Health Services Nutrition Improvement Program (NIP) has integrated a cadre of nutrition counselors into prevention of mother-to-child transmission of HIV programs, infant welfare clinics, and antenatal clinics to improve infant and young child feeding practices (IYCF). The study objective was to evaluate the effects of NIP’s infant feeding counselors on exclusive breastfeeding (EBF), complementary feeding (CF), and children’s linear growth. A cross-sectional evaluation design was used. Using systematic random sampling, caregivers were recruited from NIP sites (n = 359) and non-NIP sites (n = 415) from Infant Welfare Clinics (IWCs) in the Northwest (NWR) and Southwest Regions (SWR) of Cameroon between October 2014 and April 2015. Differences in EBF and CF practices and children’s linear growth between NIP and non-NIP sites were determined using chi-square and multiple logistic regression. After adjusting for differences in religion, occupation, and number of months planning to breastfeed, children were almost seven times (Odds Ratio [OR]: 6.9; 95% Confidence Interval [CI]: 2.30, 21.09; β = 1.94) more likely to be exclusively breastfed at NIP sites compared to non-NIP sites. After adjusting for differences in occupation, religion, number of months planning to breastfeed, rural environment, economic status, attending other Infant Welfare Clinics, and non-biological caregiver, children were five times (OR: 5.5; CI: 3.37, 9.02; β = 1.71) more likely to be stunted at non-NIP sites compared to non-NIP sites. Training a cadre of nutrition counselors is one approach towards increasing nutrition human resources to implement nutrition interventions to improve maternal and child nutrition. In this research project, the study design did not allow for conclusive results, but rather suggest IYCF counseling provided by nutrition counselors was effective in increasing EBF and reduced the risk of stunting in children 6–8 months.
