Background. Vitamin A deficiency is a public health problem in Zimbabwe. Addressing vitamin A deficiency has the potential to enhance resistance to disease and reduce mortality, especially in children aged <5 years. Objective. To describe a vitamin A supplementation outreach strategy implemented in one of the remote rural districts in Zimbabwe, which increased coverage after being implemented in difficult circumstances in a remote rural region. Methods. We implemented and adapted a vitamin A supplementation outreach strategy within the national immunisation days (NIDs) and extended programme of immunisation in a remote rural district in Zimbabwe. The strategy involved supplementating children at prescheduled outreach points once per month for the whole year. Despite usual operational challenges faced at implementation, this approach enabled the district to increase delivery of vitamin A supplements to young children in the district. Results. The strategy covered 63 outreach sites, with two sites being covered per day and visited once per month for the whole year. Coverage reached 71% in an area in which previous coverage rates were around <50%. Conclusion. Implementing a vitamin A supplementation outreach strategy increased vitamin A supplementation coverage among child ren living in a remote rural region. This strategy can potentially be used by Scaling Up Nutrition (SUN) member states. However, we recommend further exploration of this strategy by others working in similar circumstances.

AbstractPurpose -The purpose of this paper is to examine asymmetric co-integration effects between nutrition and economic growth for annual South African data from the period 1961-2013. Design/methodology/approach -The authors deviate from the conventional assumption of linear co-integration and pragmatically incorporate asymmetric effects in the framework through a fusion of the momentum threshold autoregressive and threshold error correction (MTAR-TEC) model approaches, which essentially combines the adjustment asymmetry model of Enders and Silkos (2001); with causality analysis as introduced by Granger (1969); all encompassed by/within the threshold autoregressive (TAR) framework, a la Hansen (2000). Findings -The findings obtained from the study uncover a number of interesting phenomena for the South Africa economy. First, in coherence with previous studies conducted for developing economies, the authors establish a positive relationship between nutrition and economic growth with an estimated income elasticity of nutritional intake of 0.15. Second, the authors find bi-direction causality between nutrition and economic growth with a stronger causal effect running from nutrition to economic growth. Lastly, the authors find that in the face of equilibrium shocks to the variables, policymakers are slow to responding to deviations of the variables from their co-integrated long run steady state equilibrium. Originality/value -In the study, the authors make a novel contribution to the literature by exploring asymmetric modelling in the correlation between nutrition intake and economic growth for the exclusive case of South Africa.
