Initial attributes Module

1.0 Overview

This module assigns initial simulant attributes. Specifically, it assigns the pregnant person’s age at the end of pregnancy and the broad outcome of the pregnancy, as well as three correlated propensities used for the delivery facility choice model: Antenatal care (ANC) attendance; Low birthweight and short gestation (LBWSG) category; and In-facility delivery (IFD) status. The propensities for these attributes should be correlated using a Gaussian copula as described in the correlated propensities section of the facility choice model document.

Note

In later waves of the model, we will add further items that will need to be assigned at initialization including pre-pregnancy BMI, blood pressure and/or hemoglobin levels. We will add further documentation covering how to assign these items at that time.

2.0 Module Diagram and Data

There is no need for a diagram for the initial attributes module of this simulation. Rather, a list of module outputs and instructions for how to apply them are included in the table below.

Module outputs

Output	Value	Dependencies
Maternal age at end of pregnancy	See the pregnancy demography model document for instructions	Will be used for rates of maternal disorders
Broad pregnancy outcome	One of “abortion/miscarriage/ectopic” or “live birth/stillbirth”, see Broad pregnancy outcome for instructions on how to choose	Will be used to assign ANC visit, birth outcome (which is the same as broad pregnancy outcome but with live and still births differentiated)
ANC propensity	See the correlated propensities section of the facility choice model document for instructions	Will be used to determine ANC attendance in ANC module
LBWSG category propensity	See the correlated propensities section of the facility choice model document for instructions	Will be used to determine LBWSG exposure in pregnancy module
In-facility delivery (IFD) propensity	See the correlated propensities section of the facility choice model document for instructions	Will be used to determine in-facility delivery status in delivery facility choice module
RDS intervention propensity	Use a random number between 0 and 1	Will be used to determine which simulants receive each RDS intervention (CPAP and ACS).
Anemia intervention propensity	Use a random number between 0 and 1	Will be used to determine coverage of the oral iron, anemia screening, and IV iron interventions, as described in the hemoglobin modeules
