The highest level of formal education attained

▪ No education

 Employment status

If the respondent was employed at time of survey

 Wanted index pregnancy

Refers to if the respondent wanted the pregnancy when she became pregnant

▪ Pregnancy wanted

 Number of childbirths

The number of children ever born to the respondent

▪ 1

▪ 2–3

▪ 4–7

 Number of antenatal visits

Number of antenatal visits in the index pregnancy

▪ No ANC visits

▪ less than four visits

▪ at least four visits

 Distance to health facility

Refers to how much of a problem is ‘the distance to the health facility’ in getting medical help for oneself

▪ A big problem

▪ Not a big problem

 Household wealth index

Household wealth index in the NDHS is divided into five equal categories; poorest, poorer, middle, richer, richest

In this study, we recoded wealth index into 3 categories with ‘poor’ comprising of poorest and poorer, ‘middle’ comprising of middle and ‘rich’ comprising of richer and richest

▪ Poor

▪ Middle

▪ Rich

 Exposure to mass media

Mass media exposure was generated from exposure to television, radio and newspaper

Mass media exposure was defined as ‘exposed’ for those with access to at least one of television, radio or newspaper, and ‘no exposure’ for those who had no access to any of these

▪ No exposure

▪ Exposed

 Participates in healthcare decision

This refers to whether respondent participates in decision on her healthcare

This variable was derived from the variable—person who usually decides on respondent’s health care

A respondent participates if the decision is made by respondent alone, or respondent and partner

A respondent does not participate when the decision is made by her partner alone, or someone else

▪ Participates:

▪ Does not participate

 Partner’s level of education

The highest level of education of respondent’s partner

▪ No education

▪ Primary

▪ Secondary

▪ Higher

 Partner’s employment status

This refers to whether the partner was employed at the time of the survey or not

▪ Currently employed

▪ Not currently employed

Community Variables

 Community level poverty

Community level poverty was defined as the proportion of women who are from the poorest and poorer communities

▪ Low

▪ Medium

▪ High

 Community level women’s education

Community level women’s education was defined as proportion of women from community with at least secondary education

▪ Low

▪ Medium

▪ High

Community skilled prenatal care was defined as proportion of women from community with availability of antenatal care from a skilled health provider (doctor, nurse, midwives)

▪ Low

▪ Medium

 Community level of transportation support

Community level of transportation was defined as the proportion of women from community with viable means of transportation to health facility

▪ Low

▪ Medium

 Ethnic diversity

Ethnic diversity refers to the concentration of different ethnic groups in a community

It was defined as the proportion of women from different ethnic groups in the primary sampling unit

The value ranges from 0 to 100. A value of 0 (low) reflects a mono-ethnic community, whereas a value of 100 (high) relects that the community is multi-ethnic in nature

▪ Low

▪ Medium

▪ High

 Place of residence

The place of residence if urban or rural

▪ Urban

▪ Rural

 Region

This is the geographical region which the respondent lives

▪ Northcentral

▪ Northeast

▪ Northwest

▪ Southeast,

▪ South-south

▪ Southwest

  1. Community level poverty, community level women’s education, community level of skilled prenatal support, community level of transportation support and ethnic diversity were computed by aggregating individual characteristics at the cluster level (primary sampling unit), dividing the measure into tertiles and categorizing as low, medium and high. Similar procedure has been widely applied to derive community variables in DHS datasets [21,22,23]
