Socioeconomic factors included highest educational attainment (no education, primary education, secondary education and higher), employment status (not working vs. currently working), and quintile of socioeconomic status (SES) (very low, low, medium, high, very high).
If all our pupils could reach some basic minimum standards of literacy and numeracy by the time they left primary schools, our educational attainment as a nation would be markedly higher.
We conclude that married women with educational attainment of primary education and above are less likely get married at an early age than those who are uneducated.
In the current study, education was measured as a categorical variable where participants were asked to specify their highest level of educational attainment (primary, high school, higher education diplomas and degrees).

Demographic covariates included age, sex and highest educational attainment (primary, secondary and tertiary).
Other measures recorded during the home interview (CAPI) included age, gender, highest level of educational attainment (primary, secondary or tertiary), current smoking status, history of cardiovascular disease and medication use.
Our imputation model also included educational attainment (primary or none/secondary/tertiary), age, sex, BMI, smoking status, alcohol status, SBP, blood cholesterol, diabetes, event status (yes/no), and days to event or censoring.
We included age, educational attainment (primary, secondary, or tertiary), five quintiles of household wealth based on household assets, employment status (being in paid work vs not in paid work), in-country migration (migrant vs non-migrant), ethnic background (Javanese vs non-Javanese), and religion (Moslem vs non-Moslem) as predictor variables.
Sex, chronological age group (18 29, 30 44, 45 64, ≥65 years), BMI status (non-overweight/non-obese, overweight, obese), educational attainment (primary, middle, high), and smoking status (current, former, never) were included as categorical covariables, and asthma duration in years as a continuous covariable.
