Unintended effects of a targeted maternal and child nutrition intervention on household expenditures, labor income, and the nutritional status of non-targeted siblings in Ghana.

It is common for health and nutrition interventions to target specific household members and for evaluations of their effects to focus exclusively on those members. However, if a targeted intervention changes a household's utility maximization problem or influences decision-making, households might respond to the intervention in unintended ways with the potential to affect the wellbeing of non-targeted members. Using panel data from a randomized controlled nutrition trial in Ghana, we evaluate household behavioral responses to the provision of small-quantity lipid-based nutrient supplements (SQ-LNS) to mothers and their infants to prevent undernutrition. We find that targeted supplementation with SQ-LNS had a positive effect on household expenditures on food, including some nutrient-rich food groups, as well as on non-food goods and services. We also find a positive impact on labor income, particularly among fathers. We then explore intrahousehold spillover effects on the nutritional status of non-targeted young children in the household. We find evidence that the targeted provision of SQ-LNS led to higher height-for-age z-scores among non-targeted children in the LNS group compared to the non-LNS group, though only among those with relatively taller mothers, which is an indicator of a child's growth potential. These findings support existing evidence and suggest that unintended behavioral responses and spillover are a real possibility in the context of nutrition interventions targeting nutritionally-vulnerable household members. Thoughtfully considering this possibility in the design, analyses, and evaluation of targeted nutrition interventions may provide a more complete picture of overall effects.

Willingness to pay for small-quantity lipid-based nutrient supplements for women and children: Evidence from Ghana and Malawi.

Small-quantity lipid-based nutrient supplements (SQ-LNS) are designed to enrich maternal and child diets with the objective of preventing undernutrition during the first 1,000 days. Scaling up the delivery of supplements such as SQ-LNS hinges on understanding private demand and creatively leveraging policy-relevant factors that might influence demand. We used longitudinal stated willingness-to-pay (WTP) data from contingent valuation studies that were integrated into randomized controlled nutrition trials in Ghana and Malawi to estimate private valuation of SQ-LNS during pregnancy, postpartum, and early childhood. We found that average stated WTP for a day's supply of SQ-LNS was more than twice as high in Ghana than Malawi, indicating that demand for SQ-LNS (and by extension, the options for effective delivery of SQ-LNS) may be very context specific. We also examined factors associated with WTP, including intervention group, household socioeconomic status, birth outcomes, child growth, and maternal and child morbidity. In both sites, WTP was consistently negatively associated with household food insecurity, indicating that subsidization might be needed to permit food insecure households to acquire SQ-LNS if it is made available for purchase. In Ghana, WTP was higher among heads of household than among mothers, which may be related to control over household resources. Personal experience using SQ-LNS was not associated with WTP in either site.

Maternal and Child Supplementation with Lipid-Based Nutrient Supplements, but Not Child Supplementation Alone, Decreases Self-Reported Household Food Insecurity in Some Settings.

Background: It is unknown whether self-reported measures of household food insecurity change in response to food-based nutrient supplementation.Objective: We assessed the impacts of providing lipid-based nutrient supplements (LNSs) to women during pregnancy and postpartum and/or to their children on self-reported household food insecurity in Malawi [DOSE and DYAD trial in Malawi (DYAD-M)], Ghana [DYAD trial in Ghana (DYAD-G)], and Bangladesh [Rang-Din Nutrition Study (RDNS) trial].Methods: Longitudinal household food-insecurity data were collected during 3 individually randomized trials and 1 cluster-randomized trial testing the efficacy or effectiveness of LNSs (generally 118 kcal/d). Seasonally adjusted Household Food Insecurity Access Scale (HFIAS) scores were constructed for 1127 DOSE households, 732 DYAD-M households, 1109 DYAD-G households, and 3671 RDNS households. The impact of providing LNSs to women during pregnancy and the first 6 mo postpartum and/or to their children from 6 to 18-24 mo on seasonally adjusted HFIAS scores was assessed by using negative binomial models (DOSE, DYAD-M, and DYAD-G trials) and mixed-effect negative binomial models (RDNS trial).Results: In the DOSE and DYAD-G trials, seasonally adjusted HFIAS scores were not different between the LNS and non-LNS groups. In the DYAD-M trial, the average household food-insecurity scores were 14% lower (P = 0.01) in LNS households than in non-LNS households. In the RDNS trial, compared with non-LNS households, food-insecurity scores were 17% lower (P = 0.02) during pregnancy and the first 6 mo postpartum and 15% lower (P = 0.02) at 6-24 mo postpartum in LNS households.Conclusions: The daily provision of LNSs to mothers and their children throughout much of the "first 1000 d" may improve household food security in some settings, which could be viewed as an additional benefit that may accrue in households should policy makers choose to invest in LNSs to promote child growth and development. These trials were registered at clinicaltrials.gov as NCT00945698 (DOSE) NCT01239693 (DYAD-M), NCT00970866 (DYAD-G) and NCT01715038 (RDNS).

The relationship between religion and livelihood activities of women: Empirical evidence from the Yilo and Lower Manya Krobo Districts of Eastern Ghana.

The study examines the effect of religious affiliation on livelihood activity choice amongst a sample of 1209 women in the Yilo and Lower Manya Krobo Districts of Ghana. We attempt to disentangle the effect religion would have through its effect on risk preferences, from the effect it would have due to creation of social capital or the effect of clustering due to social identity. We find evidence that there is a strong positive social capital or social identity effect of being Catholic, Pentecostal or Protestant when it comes to farming. This effect is also positive for Protestant and Catholic women for wage employment. This social capital and social identity effect is significantly negative for Catholic, Pentecostal and Protestant women in the case of petty retailing. Women who are willing to take risk are more likely to be in farming and less likely to be wage employed than risk averse women. However, the effect of risk aversion as a result of being Catholic, Protestant or Pentecostal only seems to have a negative effect in the case of farming. The risk aversion effect does not appear to act through religious affiliation when it comes to wage employment. It is recommended that any policy intervention aimed at enhancing livelihood activities of women in this area should take into consideration any relative advantage of having a specific religious affiliation. Such policies should take cognizance of both clustering and networking effects resulting from belonging to a religious group. Risk profiles of women are also important when implementing such policies. Other important considerations are age, household headship, education, dependency ratio, household farm ownership and household enterprise ownership.
