From: Effects of tobacco exposure on perinatal suicidal ideation, depression, and anxiety

Suicidal ideation vs. Perinatal perioda 1st trimester 2nd trimester 3rd trimester

 High secondhand smoke exposure 2.05 0.80 ~ 5.22 1.71*** 1.27 ~ 2.29 0.84 0.42 ~ 1.67
  1. *p < 0.05; **p < 0.01; ***p < 0.001. OR, odds ratio; CI confidence interval
  2. aModel was adjusted for perinatal period, marital status, monthly income, employment status, educational level, planned pregnancy, history of depression, sleep problems, and secondhand smoking
  3. bThe postpartum data were invalid because no participant exposed to secondhand smoke reported suicidal ideation
  4. cModel was adjusted for perinatal period, marital status, monthly income, employment status, educational level, planned pregnancy, history of depression, and sleeping problems
