Recent studies have shown that inclusion of eggs in young children’s diet can help meet nutritional requirements associated with cognitive development. This study aims to investigate the effect of egg consumption on early childhood development using Ages and Stages Questionnaire-3 in Burkina Faso.

The study presented here uses data collected during a follow-up of the Un Oeuf-a three-arm clustered randomised controlled trial (RCT), conducted roughly 4 months after the end of the RCT.

This research was conducted in eighteen rural villages within the Kaya Department of the Sanmatenga Province in Burkina Faso.

Participants of this study include a total of 244 children aged between 18 and 33 months, with seventy-eight children in the full intervention group, eighty-three in the partial group, and eighty-three in the control group.

Results show that children with consistent egg consumption (in all months) had a lower odd of falling below the cut-off scores in gross motor (${\rm{OR}} = {\rm 0\!\cdot\!13},{\it P} = \rm{0\!\cdot\!02}$) and personal social skills (${\rm{OR}} = 0\!\cdot\!34,{\it P} =0 \!\cdot\!05$). And a dose–response was established; for each additional egg/week, a 1·9 % increase in scores for problem-solving skills was observed.

Findings from this study contribute to a growing body of evidence that increasing egg consumption among children in low- and middle-income countries (LMIC) can improve growth and development. The study highlights the need for additional research in LMIC to better understand the multifactorial relationship between diet and childhood development.

To examine the height-for-age z-score (HAZ) of 0–35 months’ children along with stunting prevalence to identify trends, changes and available nutrition-sensitive and specific determinants that could help explain the long-term variation in child linear growth using successive Bangladesh Demographic and Health Surveys (BDHS) data from 1996 to 2018.

The BDHS pooled data are used for determining the key outcome variables HAZ, stunting and severe stunting. Trends, kernel-weighted local polynomial smoothing illustrations, pooled multivariable linear probability model (LPM), ordinary least squares method (OLS) and regression decomposition were used.

Mothers having 0–35 months’ children, the most critical age range for growth faltering.

The mean HAZ increased by 0·91(±1·53) with 0·041 annual average change, while the percentages of stunting (–26·63 ± 0·54) and severe stunting (–21·12 ± 0·48) showed a reduction with 1·21 and 0·96 average annual changes, respectively. The average HAZ improvement (0·42 ± 1·56) in urban areas was less than the rural areas (1·16 ± 1·44). Similar patterns followed for stunting and severe stunting. The prenatal doctor visits (3064·65 %), birth in a medical facility (1054·32 %), breastfeeding initiation (153·18 %) and asset index (144·73 %) demonstrated a huge change. The findings of OLS, LPM and regression decomposition identified asset index, birth order, paternal and maternal education, bottle-fed, prenatal doctor visit, birth in a medical facility, vaccination, maternal BMI and ever-breastfed as influencing factors to predict the long-term changes of stunting and severe stunting.

The nutrition-sensitive and specific factors identified through regression decomposition describing long-term variation in child linear growth should be focused further to attain the sustainable development goals.

This process evaluation aimed to understand factors affecting the implementation of a government-sponsored short message service (SMS) programme for delivering nutrition information to rural populations, including message access, acceptability and putting messages into action.

The study was nested within a larger randomised controlled trial. Cross-sectional data collection included structured surveys and in-depth interviews. Data were analysed for key trends and themes using Stata and ATLAS.ti software.

The study took place in Tanzania’s Mtwara region.

Surveys were conducted with 205 women and 93 men already enrolled in the randomised controlled trial. A sub-set of 30 women and 14 men participated in the in-depth interviews.

Among women relying on a spouse’s phone, sharing arrangements impeded regular SMS access; men were commonly away from home, forgot to share SMS or did not share them in women’s preferred way. Phone-owning women faced challenges related to charging their phones and defective handsets. Once SMS were delivered, most participants viewed them as trustworthy and comprehensible. However, economic conditions limited the feasibility of applying certain recommendations, such as feeding meat to toddlers. A sub-set of participants concurrently enrolled in an interpersonal counselling (IPC) intervention indicated that the SMS provided reminders of lessons learned during the IPC; yet, the SMS did not help participants contextualise information and overcome the challenges of putting that information into practice.

The challenges to accessing and implementing SMS services highlighted here suggest that such platforms may work well as one component of a comprehensive nutrition intervention, yet not as an isolated effort.
