Socioeconomic variables included monthly income, cost and time to travel to clinic, number of family members (all continuous variables), parental education (secondary level or greater vs primary level or less), and the presence of a household telephone.
Social variables included education (higher than secondary level, secondary level, primary/elementary level, no schooling) and living arrangements (living with children, living with spouse, living alone and living with others, including relatives and non-relatives).
Education was defined as a four level variable (no school/primary without diploma, primary with diploma, secondary without a baccalaureate degree, baccalaureate/university degree).
A three-class variable was constructed: primary (only primary level education), medium (secondary level or lower degree tertiary) and high (higher degree level tertiary or higher).
For the education variable, the highest level of educational attainment was used and grouped into: "no education", "elementary level", and "secondary level or higher".
