In 2011, three first-wave varieties of yellow cassava, containing 6-7 ppm of provitamin A, were released in Nigeria, while the full target (15 ppm of provitamin A) varieties are expected to be released in 2015/2016.  Initially, the target levels of provitamin A in cassava were set by using rough estimates on cassava intake (grams/day); bioconversion, the retinol equivalency of provitamin A carotenoids, and losses of provitamin A during processing and cooking. However, accurate information on the above parameters were needed to confirm our initial assumptions. A study on bioconversion was performed as well as retention studies. In the present study we aimed to assess the cassava intake and the vitamin A deficiency among women and preschool children in Nigeria.  Therefore, we conducted a cross-sectional survey in rural to moderately-urbanized areas of Akwa-Ibom, a state identified as having high cassava consumption and high prevalence of vitamin A deficiency among children under the age of 5. The specific aims of the study were: 1) to quantify the cassava and nutrient intake, and 2) to assess the vitamin A and iron status among preschool children and women of childbearing age."},"dsDescriptionDate":{"typeName":"dsDescriptionDate","multiple":false,"typeClass":"primitive","value":"2015-03-24"}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Medicine,

The sampling procedure was a multistage cluster selection process of local government areas (LGAs) and further by enumeration areas (EAs), which is the smallest geographical cluster of households. The LGAs are grouped according to the level of urbanization (rural, moderate-urban, and urban) within each state. A comprehensive list of all EAs in selected local government areas was obtained from the State National Population Commission. Of the 31 LGAs in Akwa Ibom (16 rural, 10 moderate-urban, and 5 urban), 10 were randomly selected from the 26 non-urban LGAs, followed by the random selection of three EAs within each LGA. Therefore, each LGA comprised 3 clusters for a total of 30-cluster survey or 22 households per cluster for a total of 660 households. Out of 660 households, 587 (89%) particip\r\nated in the dietary assessment and socio-economic components, and 640 mother/child pairs (97%) provided blood samples.
