Demographic variations and temporal trends in prenatal use of multiple micronutrient supplements in Beijing, 2013 – 2017

The objective of this study was to provide updated information about demographic variations and temporal trends in the prenatal use of multiple micronutrient (MMN) supplements in the metropolitan areas of China, using descriptive analysis of routine prenatal healthcare data between 2013 and 2017. Results showed that approximately two-thirds of women consumed prenatal MMN supplements during the periconceptional period in the central area of Beijing and the proportion increased over time, indicating a need to evaluate the effectiveness and safety and to develop a guideline for relatively well-nourished women.
