Measurement of outcome variables.

Outcome Variables	Measurements
Sufficient Antenatal Care (ANC) visits	This factor was assessed in the study as a dichotomous variable created from the continuous measure of the number of ANC visits during pregnancy, grouped as Sufficient ANC visits (four or more); and Insufficient ANC visits (less than four, which also includes no ANC visits). Four or more ANC visits was considered as Sufficient ANC visits based on the standard recommended by the World Health Organization (WHO) [27,28].
Delivery in a health facility (institutional delivery)	Delivery in a health facility (institutional delivery was assessed as a dichotomous variable categorized as: Institutional delivery (when the delivery was done at public, private or non-governmental health facilities); and No institutional delivery (when the delivery took place at home and others). This binary outcome variable was chosen instead of ‘skilled assistance during delivery’ to stress the utilization of institutional delivery services [23,25].
