Objectives: Adequate dietary consumption of long chain omega-3 fatty acids (n-3 LCPUFA) during pregnancy has been associated with better maternal and infant health outcomes. Given that the primary source of n-3 LCPUFA is fish and fish oils, concerns surrounding contamination and uncertainty of safe fish intake guidelines have negatively affected consumption of fish during pregnancy. Although obstetric healthcare providers are in a unique position to influence dietary intake patterns, a gap exists in their understanding the knowledge and practices surrounding n-3 LCPUFA. This needs assessment investigation evaluated knowledge, attitudes and prescribing/recommending practices of obstetric practitioners surrounding n-3 LCPUFA consumption and/or supplementation to generate evidence supporting the development of targeted educational initiatives.
Methods: A cross-sectional, needs assessment was conducted using anonymous online-survey of affiliate members of the American College of Nurse Midwives (N = 105). A 24-item, previously validated (α = 0.86) needs assessment survey (Obstetric Clinicians Omega-3 Survey, OCOS) was used to assess attitudes, knowledge, and prescribing practices surrounding n-3 LCPUFA.
Results: The total OCOS score representing attitudes, knowledge and prescribing patterns collectively was 69.48% (Mean = 79.90(± 12.44), score range = 24-115). Scores for the sub-domains included attitude 68.33% (Mean = 20.50(± 3.64), score range = 6-30); knowledge 71.40% (Mean = 30.70(± 5.43), score range = 9-43); and prescribing patterns 68.31% (Mean = 28.69(± 5.39), score range = 9-42).
Conclusions for practice: Although the majority of respondents had fair-moderate n-3 LCPUFA knowledge, attitudes and prescribing/recommending, our results highlight an opportunity for additional research and educational outreach targeting improved n-3 LCPUFA knowledge and practices. Specific areas of educational interest included associated health outcomes, dosing and safe consumption guidelines.
