Abstract Background: To determine the associations of different prenatal factors with the development of non-syndromic cleft lip or/and palate (NSCL/P), as there are still no consensus to the risk factors of NSCL/P.Methods: Nested case-control study based on the gestational period health care record data of all singleton NSCL/P (n=197) and fetuses without birth defects (n=192706) born in-hospital of Zhongshan between 2016 and 2019. Results: Vagina infected (OR 3.43, 95%CI 1.34-7.19), assisted conception (OR 11.57, 95% CI 0.65-54.29), folic acid intake <3 moths during pre- and early pregnancy (OR 1.57, 95% CI 1.10-2.30), incomplete placenta or rough surface placenta (OR 4.65, 95% CI 3.23-6.57), abnormal amniotic fluid (OR 2.74, 95% CI 2.04, 3.67), low birth weight of newborns (OR 5.44, 95% CI 3.41-8.54), preterm delivery (OR 3.29, 95% CI 2.07-5.24), and post-term delivery (OR 5.94, 95% CI 0.97-18.93) were associated with a higher risk of NSCL/P. Conclusions: The status of placenta and fluid were discovered as risk factors with NSCL/P, which strengthens the importance role of interaction between the placental barrier and various environmental factors on the development of NSCL/P.
