On March 2019, in the 62 schools supported by AVSI – 10 in LAKES (Cueibet) and 52 in EES (Torit, Magwi, Ikwoto, Kapoeta South and East) – it was conducted a nutrition screening of every student enrolled in primary two (P2) grade and in class the day of the data gathering. As schools were purposely selected (not randomly selected), the nutrition figures obtained provide reference only for the children enrolled in AVSI-supported schools.
Anthropometric measures (eight, weight and age) were gathered for a total of 2,189 P2 pupils, 1,278 of whom were estimated to be children between 5 and 10 years of age.
The Body Mass Index (BMI) was calculated only for the children between 5 and 10 years of age (as human growth is less accelerated for that age group, nutrition estimates for those children are expected to be more robust); still, enumerators gathered anthropometric data for all 2,189 pupils in order to avoid biases or distortion in the reporting of age (blind test).
Similarly, the choice to base the analysis on the BMI, rater than GAM or SAM, is aimed at reducing even further the potential errors related to the incorrect estimation of pupils’ age, as the BMI ratio varies less depending on age.
BMI cut-off points employed to classify pupils’ nutrition condition were those suggested by WHO for 9 years of age children: for females 12 for thinness and 13 for severe thinness; and for males 12.5 for thinness and 13.5 for severe thinness. (https://www.who.int/growthref/who2007_bmi_for_age/en/).
