Description of data capture Data Collection Methods: Staff were trained to collect anthropometric data at regular intervals. Recumbent length was used for children below the age of 2, while height for children above age 2 was measured using a Leicester height measure. Survey data was administered by field staff using paper questionnaires and in the local language, Chitumbuka. Data collection was supervised and managed on site by a team of scientists, field enumerators and data entry personnel. Data was then double-entered into MS Access by the data entry office for further analysis. Informed consent to participate in the study was sought from household heads. Further details on data collection methods can be found in the paper. Data Analysis and Preparation: Raw anthropometric data was transformed into height-for-age z-scores (HAZ) based on the WHO growth references for children below and above age 5. Growth failure/stunting was defined as the HAZ <-2SD. Growth trajectories between early and late childhood were defined as being never stunted, improvers (stunted in early but not stunted in late childhood), decliners (not stunted in early but stunted in late childhood) or persistently stunted (in early and late childhood). For data on school outcomes, age at entry was determined by the cut-off of age 6 (<6 being underage, >6 being overage enrolment). Age-for-grade is the number of years a child is ahead/behind in class based on the official age-for-grade and provides a cumulative measure of school performance. The effects of stunting on grade repetition in Standard 1, which is has the highest proportion of repeaters in primary school, was also examined.
