Household and market survey on availability of adequately iodized salt in the Volta region, Ghana

This is an Accepted Manuscript of an article published by Taylor & Francis in International Journal of Health Promotion and Education on 27/10/2016, available online: http://www.tandfonline.com/doi/full/10.1080/14635240.2016.1250658Consumption of adequately iodized salt (AIS) ≥15ppm is one of the criteria for measuring progress towards universal salt iodization (USI) and sustainable elimination of iodine deficiency disorders. After series of health promotion activities, this survey was conducted to evaluate the extent to which USI was achieved. Cross-sectional survey was conducted in 1,961 households and 350 markets to estimate the iodine levels of salt consumed or sold. Three degrees of iodization were estimated from fine, coarse and granular texture salt using MBI rapid field test kits. Differences in iodization levels were determined using Bonferroni test in STATA. Determinants for household utilization of AIS were identified using regression analysis and reported as odds ratio (OR). Availability of AIS in households (24.5%) and markets (30.9%) was far below the 90% recommendation. No differences where observed in urban (26.8%) and rural (24.1%) households. Households that used fine-texture salt (OR: 40.13; CI: 30.1-53.4) or stored salt in original packs (OR: 8.02; CI: 6.01-10.70) were more likely to consume AIS. Across districts, highest household availability of AIS was 51.7% while the least was 7.5%. The district with the highest market availability of AIS was 85.7% while the least was 8.3%. Almost 32% of the traders were aware that selling non-iodized salt was unauthorized but out of this, only 12% sold AIS. Public education should emphasis appropriate handling and storage of salt throughout the supply chain. To ensure adequate salt fortification with iodine, improved surveillance of factories and mining sites is recommended

Agricultural exports and economic growth in less developed countries

This article examines the contribution of agricultural exports to economic growth in less developed countries (LDCs). A sources-of-growth equation is developed from a dual economy model where agricultural and nonagricultural sectors are both divided into export and nonexport subsectors. This is then estimated using panel data for 62 LDCs for 1974-1995. Results provide evidence that there are significant structural differences in economic growth between low, lower-middle, and upper-income LDCs. Investment in the agricultural export subsector has a statistically identical impact on economic growth as investment in the nonagricultural export subsector. The marginal productivities in nonexport subsectors are over 30% lower than those in respective export subsectors. From a policy perspective, the results suggest that export-promotion policies should be balanced. Copyright 2005 International Association of Agricultural Economics.
