Context:
Improving maternal nutrition and promoting alcohol abstinence during pregnancy are key to reducing subsequent economic and social impacts. However, antenatal nutrition and alcohol interventions are underused, partly because economic evidence to support investment is limited.
Objective:
The purpose of this systematic literature review was to assess the extent to which economic evaluations have been applied to antenatal public health interventions, and implementation strategies addressing maternal nutrition and alcohol intake.
Data Sources:
Two separate systematic reviews were conducted to address the 2 stated aims. Both reviews adhered to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The searches were conducted using the following databases: Medline, EMBASE, Cochrane, EconLit, CINAHL, and the National Health Service Economic Evaluation Database, accompanied by a handsearch of gray literature.
Data Extraction:
Review 1 returned 9599 records after duplicates were removed, from which 12 economic evaluations were included. Review 2 returned 136 records after duplicates were removed, with none eligible for inclusion. The articles included in review 1 comprised 10 economic evaluations of nutrition interventions and 2 evaluations of alcohol interventions.
Data Analysis:
Methodological quality was assessed using the Drummond 10-point quality checklist. Methodological quality was high, with variation in reporting practices and predominance of modeled evaluations.
Results:
Antenatal nutrition and alcohol interventions offer value for money and have potential to considerably reduce healthcare costs. No evidence regarding intervention implementation cost was identified.
Conclusion:
The current evidence base has important gaps that limit its value to decision makers. Incorporating health economic principles and methods into health promotion interventions will inform decisions about how to derive value from investment in healthcare.
