Abstract
WHAT IS ALREADY KNOWN ON THIS TOPIC? Neural tube defects can be effectively prevented by folic acid supplementation. However, compliance with the recommendations for supplementation is still low in China. WHAT IS ADDED BY THIS REPORT? This study investigated the rate of correct use of folic acid supplementation and its risk factors among pregnant women in Beijing. Women who took folic acid correctly only comprised less than 50% of the total, possibly due to unexpected pregnancy. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? Given the low rate in Beijing, an area with high health literacy, the rate may also be low in other areas in China. Regulations for mandatory fortification of food with folic acid are recommended in China.
