Hi there, I observed that 22 countries out of the 34 SSA countries I am working with have 50% or more of the BMI data missing for adult females. I am aware that in these countries BMI data was collected by randomly sampling a smaller subset of the larger DHS sample. However, I was wondering why fewer people were sampled for BMI in recent years. Is it due to reasons of cost or something else?

Subsamples are used for questions or biomarkers in many DHS surveys for a variety of reasons, including cost savings, ensuring data quality by reducing the total interview time, the lack of a need of estimates of certain indicators at the lowest administrative level, or the fact that similar information was recently collected in another survey.
