Oral Diseases (2011) 17 , 584–589 Objective: To explore the risk factors of non‐syndromic orofacial clefts. Subjects and Methods: A case–control study was conducted in China, 537 infants born with non‐syndromic cleft lip with/without cleft palate, 176 infants born with cleft palate (CP), and 221 normal controls were recruited to participate in a questionnaire based study to identify risk factors related to maternal nutrition. Results: Single‐factor Chi‐square analysis identified 12 factors as significantly related to non‐syndromic orofacial clefts ( P < 0.05). Multiple logistic regression showed five of these factors were associated with non‐syndromic orofacial clefts, male gender and maternal passive smoking during early pregnancy were risk factors for non‐syndromic orofacial clefts (OR = 1.86 and 11.42; 95%CI: 2.28–2.69 and 6.87–19.00, respectively), whereas maternal weight gain during pregnancy and folic acid supplementation during early pregnancy were protective (OR = 0.15 and 0.67; 95%CI: 0.034–0.63 and 0.44–1.00, respectively). Conclusions: Our data may provide references for cleft lip and CP prevention programs, and counseling programs in China.
