Risky drinking patterns are being continued into pregnancy: a prospective cohort study

Area of Science:

• Public Health
• Obstetrics
• Addiction Medicine

Background:

• Risky alcohol use before pregnancy poses risks to both mother and child.
• Understanding changes in alcohol consumption during pregnancy is vital for intervention.

Purpose of the Study:

• To characterize women with risky drinking patterns before pregnancy.
• To analyze how these drinking patterns evolve upon becoming pregnant.

Main Methods:

• Analysis of 1577 women from the Australian Longitudinal Study on Women's Health (1973-78 cohort).
• Inclusion criteria: first pregnancy between 2000-2009 and pre-pregnancy risky drinking.
• Multinomial logistic regression to identify predictors of continued risky drinking.

Main Results:

• Pre-pregnancy, 46% reported binge drinking only, 48% reported both binge and weekly drinking.
• Women with binge drinking patterns often faced financial stress, lacked partners, smoked, used drugs, were nulliparous, experienced relationship violence, and had lower education.
• 46% of women continued risky drinking into pregnancy; 40% reduced, and 14% ceased consumption.

Conclusions:

• Over one-third of women persist with risky alcohol use during pregnancy, with binge drinking being particularly common.
• Findings highlight the necessity of addressing alcohol consumption behaviors before pregnancy.
