RESUMEN
Objective:To analyze the incidence of congenital cleft lip and cleft palate in Shanxi province and its trend from 2010 to 2020.Methods:The clinical data of perinatal infants from 2010 to 2020 were collected from Shanxi Provincial Hospital Monitoring System, and the distribution, prenatal diagnosis, the incidence of cleft lip, cleft palate, and the trend were analyzed.Results:From 2010 to 2020, among 843 457 prenatal infants in Shanxi province, there were 1 264 cases of cleft lip and/or cleft palate with an overall incidence rate of 1 4.99/10 4. Among them 199 cases were cleft palate (15.74%) with an incidence rate of 2.36/10 4; 358 cases were cleft lip (28.33%) with an incidence rate of 4.24/10 4; 707 cases were cleft lip with cleft palate (55.93%) with an incidence rate of 8.38/10 4. The overall incidence of cleft lip and/or cleft palate was significantly decreased from 2010 to 2020 ( χ2=104.04, P<0.001). The incidence of cleft lip in rural area was higher than that in urban areas (19.13/10 4vs. 11.50/10 4, χ2=81.29, P<0.001); the incidence in male infants was higher than that in female infants (16.41/10 4vs. 13.41/10 4, χ2=90.59, P<0.001). There were significant differences in the incidence of cleft lip and cleft palate among different maternal ages ( χ2=58.40, P<0.001); the incidence in maternal age<20 years (21.66/10 4) and 20-<25 years (21.06/10 4) was higher than that of other groups. The proportion of prenatal diagnosis of total cleft lip was 27.85% (352/1 264), which showed an increasing trend ( χ2=6.96, P=0.008). Conclusion:From 2010 to 2020, the incidence of congenital cleft lip and palate in Shanxi province shows a decreasing trend, while the prenatal diagnosis rate shows an increasing trend.
