Objective: Being a mother of a young child may be protective against alcohol misuse for some, but not all, women. This is the first paper to identify the mental health and psychosocial correlates of alcohol misuse among postpartum mothers.
Methods: Mothers with a child under 12-months (n=319) were recruited via social media to complete a cross-sectional online survey. Two hierarchical logistic regressions examined unique factors associated with heavy episodic drinking and hazardous alcohol use, including sociodemographic, mental ill-health, and psychosocial factors.
Results: On average, mothers drank alcohol at low levels (4 drinking days, 9 standard drinks in the past month). One in 10 (11.6%) reported heavy episodic drinking during this time and 1 in 12 (8.5%) were drinking at hazardous or greater levels. In the final models, older age and more severe postpartum anxiety were associated with higher likelihood of hazardous drinking (OR=1.37, OR=1.09, respectively), while breastfeeding was associated with lower odds of heavy episodic drinking (OR=0.29). Greater perceived social support was associated with lower odds of heavy episodic (OR=0.56) and hazardous drinking (OR=0.39), while higher coping-with-anxiety and social drinking motives were associated with greater odds of both forms of alcohol misuse (ORs=3.51-10.40). Conformity drinking motives (e.g., drinking to avoid social rejection) were negatively associated with heavy episodic drinking (OR=0.24).
Conclusions: Maternal anxiety, coping-with-anxiety and social drinking motives, and reduced social support are important factors associated with postpartum alcohol misuse. These modifiable factors are potential targets for screening and intervention for mothers who may need additional support and preventative care.
