Hicks, M., Tough, S., Johnston, D., Siever, J., Clarke, M., Sauve, R., Brant, R., & Lyon, A. (2014). T-ACE and predictors of self-reported alcohol use during pregnancy in a large, population-based urban cohort. The International Journal Of Alcohol And Drug Research, 3(1), 51-61. doi:10.7895/ijadr.v3i1.117
Aims: To determine 1) the relationship between T-ACE score and maternal self-reported alcohol use prior to and during pregnancy, and 2) the relationship between T-ACE score and maternal demographics, mental health and life circumstances.
Design: Prospective, population-based cohort study.
Setting: Three urban maternity clinics in Calgary, Canada.
Participants: 1,929 pregnant women attended by family physicians at low-risk maternity clinics.
Measures: Women completed three standardized questionnaires over the telephone in the first and third trimesters and eight weeks post-delivery, including the T-ACE and questions about drug and alcohol use, demographics, mental health and life circumstances.
Findings: 43.6% of subjects had a positive T-ACE score at intake (score 2 or greater). A positive T-ACE score was predictive of alcohol use throughout pregnancy, although most women reported no alcohol after the first trimester (93.1%). Multivariate analysis indicated that a positive T-ACE score was significantly associated with being less than 30 years of age; being Caucasian; smoking during pregnancy; having an income of less than $80,000 per annum; having a history of depression; having a history of alcohol use and binge drinking during a previous pregnancy; lower social support; and poor network orientation.
Conclusions: There was a positive association between the T-ACE score and maternal self-report of alcohol use, poor mental health and poor social support. Routine use of the T-ACE to assess for risk of an alcohol-exposed pregnancy may also help identify women with complex needs who could benefit from additional prenatal support.
