Table 2 Odds ratios (95% CI) and prevalence percentages of SGA and PTB and maternal alcohol intake during pregnancy

From: Preterm birth and small for gestational age in relation to alcohol consumption during pregnancy: stronger associations among vulnerable women? results from two large Western-European studies

  ABCD study KiGGS study  
Abstainer Non-daily drinker Daily drinker Abstainer Non-abstainer
N = 3049 N = 1894 N = 295 N = 14089 N = 2012
SGA      
Prevalence 9.0 8.3 6.8 9.5 9.5
Crude Model 1.00 0.94 (0.76, 1.15) 0.72 (0.44, 1.16) 1.00 1.01 (0.84, 1.21)
Full Model 1.00 1.14 (0.91, 1.43) 0.77 (0.47, 1.27) 1.00 0.98 (0.81, 1.19)
PTB      
Prevalence 5.5 4.1 1.7 6.5 4.8
Crude Model 1.00 0.73 (0.56, 0.97) 0.30 (0.12, 0.73) 1.00 0.71 (0.54, 0.93)
Full Model 1.00 0.77 (0.58, 1.04) 0.31 (0.13, 0.77) 1.00 0.75 (0.57, 0.99)
  1. Full Model: adjusted for education, smoking during pregnancy, maternal height, parity, BMI, maternal age, ethnicity, maternal distress (in ABCD study only) and hypertension (in ABCD study only).
  2. For all analyses on SGA, parity was excluded, because SGA is corrected for parity by definition.
  3. CI = confidence interval; SGA = small for gestational age; PTB = preterm birth;
