  1. OR, odds ratio aAdverse birth outcomes included low birth weight, prematurity, and stillbirthResults are expressed as logistic regression coefficients of adverse birth outcomes with exposure categories
  2. Model 1 is adjusted for maternal age, education level and employment status
  3. Model 2 is adjusted as for model 1 and for gravidity
  4. Model 3 is adjusted as for model 2 and for secondhand smoking exposure in Indonesian cohort or anemia-associated-comorbidities in Ghanaian cohort
