Hispanic Women's Perceptions of Neural Tube Defects and Folic Acid Supplementation: A Qualitative Study.

INTRODUCTION

In the United States, the prevalence of neural tube defects (NTDs) is higher among infants born to Hispanic women compared with those born to non-Hispanic women. The purpose of this study is to investigate perceptions of NTDs and the use of folic acid and folate as a preventive measure among Hispanic women.

METHODS

Purposive sampling was used to recruit Hispanic women from a prenatal clinic in a Northeastern metropolitan city. In-depth interviews were conducted by native Spanish-speaking researchers using a semistructured interview guide. Thematic analysis was used to develop themes related to a priori domains.

FINDINGS: The study sample consisted of 26 Hispanic women representing nine countries of origin. Four themes were revealed: dietary sources of folic acid, awareness of folic acid supplementation and fortification, preferences for receiving health information, and factors in decision-making concerning an NTD diagnosis.

CONCLUSIONS

This study highlights the importance of early and targeted educational interventions sensitive to the cultural needs of this population. Results suggest that current NTD health education efforts may not be sufficient to increase our participants' knowledge of NTD. Additionally, the disparity may be multimodal, potentially influenced by insufficient understanding of prenatal folic acid use and the role of religiosity in decision-making during pregnancy. If Hispanic women are more likely to continue pregnancies affected by NTDs, this factor could be a part of NTD disparities. Exploring factors beyond supplementation and fortification that might influence rates of NTDs at birth in the U.S. Hispanic population can help to inform prevention efforts.
