This study examined whether administering the instruction with a practice question may help interviewers identify the means by which individual children signal incomprehension. We examined 446 interviews with children questioned about abuse, including 252 interviews in which interviewers administered the instruction with a practice question (4- to 13-year-old children; Mage = 7.7). Older children more often explicitly referred to incomprehension when answering the practice question and throughout the interviews, whereas younger children simply requested repetition or gave "don't know" responses, and individual children's responses to the practice questions predicted their responses later in the interviews. Similarly, older children were more likely to seek confirmation of their understanding of interviewers' questions and to request specification. The results highlight the need for interviewers to test and closely monitor younger children's responses for ambiguous signs of incomprehension.This paper reviews and analyses the importance of maize as staple food in Eastern and Southern Africa (E&SA) and contributes in understanding the nexus between maize nutritional composition and prevalence of micronutrient deficiencies (MNDs) in these regions. MNDs remain a major public health concern particularly for women and children, with calcium, iodine, iron, selenium, zinc, folate and vitamin A deficiencies being the most common. Estimates of their prevalence are among the highest in E&SA iron-deficient anemia affected 26 to 31% of women of reproductive age, and deficiencies up to 53%, 36%, 66%, 75% and 62% f
