The present study aimed to investigate the associations of maternal folate intake from diet and supplements with the risk of SGA births using data from a cross-sectional study in Shaanxi Province of Northwest China. A total of 7307 women who were within 12 months (median 3; 10th\u201390th percentile 0\u20137) after delivery were included. Two-level models were adopted to examine the associations of folate (dietary folate, supplemental folic acid and total folate) intake with the risk of SGA births and birth weight <jats:italic>Z<\/jats:italic> score, controlling for a minimum set of confounders that were identified in a directed acyclic graph. Results showed that a higher supplemental folic acid intake during the first trimester was negatively associated with the risk of SGA births (\u226460 d <jats:italic>v<\/jats:italic>. non-use: OR 0\u00b780; 95 % CI 0\u00b766, 0\u00b796; &amp;gt;60 d <jats:italic>v<\/jats:italic>. non-use: OR 0\u00b778; 95 % CI 0\u00b765, 0\u00b794; <jats:italic>P<\/jats:italic><jats:sub>trend<\/jats:sub> = 0\u00b7010; per 10-d increase: OR 0\u00b797; 95 % CI 0\u00b795, 0\u00b799). A higher total folate intake during pregnancy was associated with a reduced risk of SGA births (highest tertile <jats:italic>v<\/jats:italic>. lowest tertile: OR 0\u00b777; 95 % CI 0\u00b764, 0\u00b794; <jats:italic>P<\/jats:italic><jats:sub>trend<\/jats:sub> = 0\u00b7010; per one-unit increase in the log-transformed value: OR 0\u00b781; 95 % CI 0\u00b769, 0\u00b795). A similar pattern was observed for the birth weight <jats:italic>Z<\/jats:italic> score. Our study suggested that folic acid supplementation during the first trimester and a higher total folate intake during pregnancy were associated with a reduced risk of SGA
