Maternal alcohol use, adverse neonatal outcomes and pregnancy complications in British Columbia, Canada: a population-based study

Table 2 Logistic regression between maternal attributes and alcohol use during pregnancy identified as a risk factor

Risk factor	OR	Lower 95% CI	Upper 95% CI	P-value
Maternal Age	0.91	0.90	0.92	< 0.001^**
Parity primiparous (relative to multiple)	1.51	1.30	1.76	< 0.001^**
Number of living children^a	1.26	1.18	1.34	< 0.001^**
Prior neonatal death	1.86	0.78	3.73	0.116
Prior stillbirth	1.02	0.48	1.87	0.952
Prior low birthweight newborn (< 2500 g)	0.65	0.37	1.05	0.104
Prior major congenital anomaly	1.1	0.52	2.04	0.786
Maternal history of any mental illness	2.62	2.35	2.92	< 0.001^**
Number of antenatal visits^a	0.96	0.95	0.98	< 0.001^**

^aThis was run as a continuous variable; the OR represents the effect size for each unit increase, or the odds for alcohol use being identified as a risk factor in each maternal record
^**Significance of produced odds ratio has alpha = p < 0.001
