Lb. Manwell et al., Treatment of problem alcohol use in women of childbearing age: Results of a brief intervention trial, ALC CLIN EX, 24(10), 2000, pp. 1517-1524
Background: Studies suggest that 14% of women age 18 to 40 drink alcohol ab
ove recommended limits. Of special concern is the increasing use of alcohol
by women during pregnancy. This article reports 48 month follow-up data fr
om a subanalysis of a trial for early alcohol treatment (Project TrEAT) foc
used on women of childbearing age.
Methods: Project TrEAT was conducted in the offices of 64 primary care, com
munity-based physicians from 10 Wisconsin counties. Of 5979 female patients
ages 18 to 40 who were screened for problem drinking, 205 were randomized
into an experimental group (n = 103) or control group (n = 102). The interv
ention consisted of two 15 min, physician-delivered counseling visits that
included advice, education, and contracting by using a scripted workbook. A
total of 174 subjects (85%) completed the 48 month follow-up procedures.
Results: No significant differences were found between the experimental and
control groups at baseline for alcohol use, age, socioeconomic status, smo
king, depression or anxiety, conduct disorder, lifetime drug use, or health
care utilization. The trial found a significant treatment effect in reduci
ng both 7 day alcohol use (p = 0.0039) and binge drinking episodes (p = 0.0
021) over the 48 month follow-up period. Women in the experimental group wh
o became pregnant during the follow-up period had the most dramatic decreas
es in alcohol use. A logistic regression model based on a 20% or greater re
duction in drinking found an odds ratio of 1.93 (confidence interval 1.07-3
.46) in the sample exposed to physician intervention. Age, smoking, depress
ion, conduct disorder, antisocial personality disorder, and illicit drug us
e did not reduce drinking significantly. No significant differences were fo
und in health care utilization and health status between groups.
Conclusions: This trial provides the first direct evidence that brief inter
vention is associated with sustained reductions in alcohol consumption by w
omen of childbearing age. The results have enormous implications for the U.
S. health care system.
