Data-centric AI governance for responsible organizational value: Evidence from a European public administration
This paper explores how data-centric artificial intelligence governance frameworks enable responsible organizational value creation within complex institutional environments. Using an empirical case from a European public administration, it examines the implementation of an automated legislative monitoring system designed to detect, classify, and summarize regulatory information. The study highlights the shift from model-centric experimentation t…
Breastfeeding counselling mentorship programme feasibility: A mixed-methods study
Objectives: To determine the feasibility of implementing a facility-based breastfeeding counselling (BFC) mentorship programme and its effect on mentee confidence and client perceptions of BFC. Setting: Mbagathi County Referral Hospital in Nairobi, Kenya. Participants: Health facility management, health workers (twenty-one mentees and seven mentors), 120 pregnant women in the third trimester who attended an antenatal care (ANC) appointment at Mba…
The impact of a counselling intervention on nutrition practices among caregivers of children under two in the Kyrgyz Republic
Objective: To evaluate the impact of a counselling programme to strengthen the health and nutrition behaviours of caregivers of children under 2 and the sustainability of that impact through reduced intervention intensity one year later. Design: The programme trained community- and facility-based health staff to provide nutrition counselling. We conducted an impact evaluation with a modified stepped-wedge design using difference-in-differences an…
Assessing the performance of national sentinel food lists at subnational levels in six countries
Objective: To assess how well national sentinel lists of the most frequently consumed foods in each food group capture data at subnational levels to measure minimum diet diversity (MDD). Design: We analysed data from seven surveys with 24-h open dietary recalls to evaluate: (1) the percentage of reported foods that were included in each sentinel food list; (2) whether these lists captured consumption of some food groups better than others and (3)…
Risk factors for anaemia among women and their young children hospitalised with suspected thiamine deficiency in northern Lao PDR
Anaemia among women and young children remains a major public health concern. This secondary study describes the anaemia prevalence among young hospitalised children and their mothers in northern Lao People's Democratic Republic and explores possible nutritional causes and risk factors for anaemia. Hospitalised children (ages 21 days to <18 months) with clinical symptoms suggestive of thiamine deficiency disorders were eligible along with their m…
Attitudes, beliefs and social norms regarding infant and young child feeding among Nigerian mothers, fathers and grandmothers across time
Infant and young child feeding (IYCF) interventions in low-resource countries mainly target pregnant women and mothers of young children; however, fathers and grandmothers also influence IYCF practices. We conducted focus group discussions with mothers, fathers and grandmothers of young children across three time points in areas where an IYCF social and behaviour change intervention was implemented in Nigeria to explore differences by participant…
Micronutrient deficiencies among preschool-aged children and women of reproductive age worldwide: A pooled analysis of individual-level data from population-representative surveys
BACKGROUND: Micronutrient deficiencies compromise immune systems, hinder child growth and development, and affect human potential worldwide. Yet, to our knowledge, the only existing estimate of the global prevalence of micronutrient deficiencies is from over 30 years ago and is based only on the prevalence of anaemia. We aimed to estimate the global and regional prevalence of deficiency in at least one of three micronutrients among preschool-aged…
Exclusive breastfeeding: Measurement to match the global recommendation
The World Health Organization (WHO) and United Nations Children's Fund (UNICEF) recommend exclusive breastfeeding (EBF) for the first 6 months of life. To estimate the proportion of infants that are exclusively breastfed, many agencies use the point prevalence of EBF among infants currently 0-5.9 months of age, as recommended by WHO and UNICEF. This measure tends to overestimate the percentage of infants that are exclusively breastfed for the ent…
Measuring coverage of infant and young child feeding counselling interventions: A framework and empirical considerations for survey question design
Most countries implement nutrition counselling interventions as part of programmes to support breastfeeding and complementary feeding. However, data to track coverage of counselling interventions are rarely available. As a result, little is known about the coverage of counselling on infant and young child feeding (IYCF). Survey-based data collection systems generally collect data on IYCF practices but do not collect data on coverage of interventi…
Lessons from using cluster-randomized evaluations to build evidence on large-scale nutrition behavior change interventions
Importance of coverage and quality for impact of nutrition interventions delivered through an existing health programme in Bangladesh
Understanding implementation of interventions is critical to illuminate if, how, and why the interventions achieve impact. Alive & Thrive integrated a nutrition intervention into an existing maternal, neonatal, and child health (MNCH) programme in Bangladesh, documenting improvements in women's micronutrient supplement intake and dietary diversity. Here, we examined how well the nutrition intervention was implemented and which elements of impleme…
Suaahara in Nepal: An at‐scale, multi‐sectoral nutrition program influences knowledge and practices while enhancing equity
The burden of undernutrition in South Asia is greater than anywhere else. Policies and programmatic efforts increasingly address health and non-health determinants of undernutrition. In Nepal, one large-scale integrated nutrition program, Suaahara, aimed to reduce undernutrition among women and children in the 1,000-day period, while simultaneously addressing inequities. In this study, we use household-level process evaluation data (N = 480) to a…
The Association of a Large-Scale Television Campaign With Exclusive Breastfeeding Prevalence in Vietnam
Objectives. To examine the association between exposure to breastfeeding television spots and exclusive breastfeeding (EBF). Methods. We performed face-to-face interviews with 11 722 mothers of infants younger than 6 months using 5 cross-sectional surveys 6 or more months apart between 2011 and 2014 in Vietnam. Sample sizes were 2065 to 2593, and approximately 50% of participants lived in areas with (Alive & Thrive [A&T]-intensive [I]) and approx…
Exposure to mass media and interpersonal counseling has additive effects on exclusive breastfeeding and its psychosocial determinants among Vietnamese mothers
The pathways through which behavior change interventions impact breastfeeding practices have not been well studied. This study aimed to examine: (1) the effects of exposure to mass media and interpersonal counseling on exclusive breastfeeding (EBF) and hypothesized psychosocial determinants (i.e. knowledge, intention, beliefs, social norms, and self-efficacy); and (2) the pathways through which exposure to mass media and interpersonal counseling …
Integrating a project monitoring system into a public health network: Experiences from Alive & Thrive Vietnam
Little information is available about how to build a monitoring system to measure the output of preventive nutrition interventions, such as counselling on infant and young child feeding. This paper describes the Alive & Thrive Vietnam (A&T) project experience in nesting a large-scale project monitoring system into the existing public health information system (e.g. using the system and resources), and in using monitoring data to strengthen servic…
