Objective: To analyze the population prevalence and birth prevalence of oral clefts in Colombia from 2009 to 2017. Methods: A cross-sectional study using information from the National Administrative Records of Colombia. The data came from 2 types of administrative records (Surveillance System and the Individual Registry of Service Provision) and the oral health national survey. Population prevalence and birth prevalence by type of cleft lip and/or cleft (CL/P) ratios were calculated using Poisson distribution for count data and to assess stationary tests on time series (Dickey-Fuller) and (Phillips-Perron) was used. Results: Population prevalence in Colombia was 3.27 per 10 000 inhabitants (95% confidence interval [CI], 3.21-3.32) and birth prevalence was 6.0 per 10 000 live births (95% CI, 5.67-6.35). Bogotá have the highest population prevalence with CL/P. In the analysis of trends for the prevalence proportion by type of clefts in newborn babies with cleft, it was observed that the highest proportion was for babies with CLP. Cleft lip (CL) has increased from 17.4% in 2014 to 34.2% in 2017, cleft palate (CP) has decreased from 32.9% to 20.2%; and CLP changed from 49.6% to 45.5% in the same period. Conclusions: The population prevalence was 3.27 per 10 000 inhabitants. Births prevalence was 6.0 per 10 000 live births, and Orinoquia and Amazonia have higher rates than the national average. The administrative registers are adequate systems to know the behavior of oral clefts. The CL/P had a nonstationary trend during the period 2014 to 2017.

Determine the population prevalence and trends of cleft lip and/or palate (CL/P) by department for Colombia in the period 2009 to 2015. Prevalence study based on Individual Registry of Health Services in general population from 2009 to 2015. All people diagnosed with CL/P were included for all ages, type of diagnosis, and any type of health services in the mentioned period. The prevalence was calculated by period and point for each year, for each department and according to the type of cleft. Stationarity on time series was evaluated using (Dickey-Fuller) and (Phillips-Perron). A trend test was applied to estimate whether the increase in prevalence was significant in the period. The trend test used was a Poisson regression. A total 15 225 people with CL/P were identified, where 53.3% were men. The national period prevalence of CL/P is 3.37 per 10 000 with upward trend (prevalence ratio = 1.34, P = .05) and nonstationary behavior. The national period prevalence of cleft lip is 0.93 per 10 000, cleft palate 1.17 per 10 000, and cleft lip and palate (CLP) 1.26 per 10 000, where CLP is subclassify into unilateral CLP (0.83 per 10 000) and bilateral CLP (0.43 per 10 000). At the departmental level, the highest CL/P prevalence is Guaviare (11.2), followed by Guainía (8.4) and the lowest Quindío (0.49). In Colombia, the national period prevalence of CL/P is 3.37 per 10 000 with upward trend at national level indicates an increase in prevalence from 2009 to 2015. The 77% of the total CL/P population are infant or adolescent. Geographically, the central region has the highest availability of technologies.
