“…The authors mentioned that this temporal trend of increasing prevalence of orofacial clefts, limited to the poorest regions of the country, may be attributed to changes in risk factors, as well as to the improvement of the record-taking process for this malformation in the SINASC. 15 Considering geographic regions individually, our study observed no consistency in the increase or decrease in the number of records between the years 2009 and 2013, except for the Southeast, which presented a steadily increasing trend. Taking into account the country as a whole, the authors of this study observed a slightly increasing trend in the period studied (Figure 2).…”

“…Another study carried out later with data between 1998 and 2002 found a prevalence rate of 3.6 per 10,000 live births. 14 Recently, Abreu et al 15 reported an overall prevalence of 4.85 per 10,000 live births, up from 3.94 to 5.46 between 2000 and 2013. In this study, it was observed that this trend occurred mainly in the Northeast (4.7% per year), the North (3.3% per year) and the Center-West (2.9% per year).…”

“…13 Knowing the prevalence of patients with orofacial clefts per region can help reduce the inequality in obtaining treatment. Rodrigues et al 13 and, more recently, Abreu et al, 15 used data from the National Live Birth System (SINASC) to estimate the prevalence of live births with orofacial clefts, considering Brazil's different geographic regions as the units of analysis.…”

The objective of this study was to investigate the prevalence of live births with orofacial clefts in Brazil from 2009 to 2013, according to Brazil's federative units and regions, and correlate it with the number of corrective surgery procedures for cleft lip and palate performed through the Brazilian National Health System in the same period. The data were collected from the National Live Birth System (SINASC in Portuguese) and the Hospital Information System (SIH-SUS in Portuguese). The results showed that the average prevalence of oral clefts in the period was 5.86 per 10,000 live births, with differences observed between the federative units and the regions. The correlation between the prevalence of orofacial clefts and the number of medical procedures associated with this anomaly was statistically significant (r=0.94; p <0.001). This result indicates that greater investments are being made in areas with a higher number of cases. The relationship between supply and demand for corrective surgeries suggests that only 18.91% of the live births with orofacial clefts in this period may have received this service under the Brazilian National Health System.

“…The presence of cleft was associated with prematurity, race/color white, children of mothers with age greater than or equal to 35 years old and worse conditions of vitality at birth. [12][13][14][15][16] The average rate of cleft lip and/or cleft palate was 0.51/1000 live births; corroborating an analysis carried out in the period from 2000 to 2013 that pointed to a national average of 0.48/1000 live births. 13 As regards the Brazilian regions most affected by this anomaly, the South and Southeast regions presented higher rates, a fact that is consistent with the literature, in which the higher prevalence of cleft lip and/or cleft palate in Brazil was verified in the South region, being the lowest rate corresponding to the northeast region.…”

Objectives: to analyze the trend and the associated factors with the presence of cleft lip and/or cleft palate in Brazilian newborns, in order to verify possible associations with maternal care and newborn factors. Methods: a cross-sectional and ecological study, involving all live births in Brazil, recorded in the Information System on Live Births from 2005 to 2016. Maternal and infant information were evaluated using trend analysis and odds ratio, with a 95% confidence interval. The analyses were performed using SPSS software. Results: we analyzed 17,800 live births with presence of cleft lip and/or cleft palate. The Brazilian prevalence rate was 0.51 / 1000 live births, with South and Southeast Regions registering higher rates than the national rate. There was an association with maternal age above 35 years old, with no partner, less than seven prenatal consultations, premature birth and cesarean section. About the factors of the newborn, being male, Apgar less than seven in the 1st and 5th minutes of life, low birth weight and white color were associated. Conclusions: Brazil has an increasing tendency for cleft lip and/or cleft palate (p=0.019), reinforcing the need to strengthen health care networks, providing adequate support for newborn with cleft lip and/or cleft palate and their families.

“…This CP underreporting was described by Nunes et al () with data from cleft patients investigated at treatment centers in Campos dos Goytacazes, in Rio de Janeiro, Brazil and was different from that recorded in the SINASC database in the same period and for the same population. However, the pattern of the CLP‐deficient frequency that we observed has already been published with the SINASC data from Mato Grosso do Sul in 2003–2007 (Gardenal, Bastos, Pontes, & Bogo, ) and from Brazil in 2009–2013 (Sousa & Roncalli, ), and 2000–2013 (Abreu et al, ), although this issue was not thoroughly discussed. Thus, assuming that the combined CL and CLP represent 74% of clefts, as described by Loffredo, Freitas, and Grigolli () in Brazil, and considering that CP is more under‐reported than other types of clefts, it is likely that the high CLP under‐reporting observed in the SINASC data is the result of encoding issues rather than of deficiencies related to case ascertainment.…”

We compared Brazilian oral cleft (OC) frequencies between the population-based Brazilian System of Live Birth (SINASC) and the hospital-based Latin American Collaborative Study of Congenital Malformations (ECLAMC), trying to understand the paucity of cleft of lip and palate (CLP) in the first system. SINASC uses the International Classification of Disease version 10 (ICD-10) for congenital defects coding, ECLAMC uses ICD-8 with modifications. In SINASC, the CLP frequency was 1.7 per 10,000 (95% confidence limits 1.7-1.8), cleft lip (CL) 1.6 (1.5-1.7), and cleft palate (CP) 2.0 (1.9-2.1). In ECLAMC, the CLP frequency was 10.4 per 10,000 (9.0-12.1), CL 5.5 (4.5-6.7), and CP 4.4. (4.5-6.7). In SINASC, only 33% of the oral clefts were CLP, versus 51% in ECLAMC. Part of this discrepancy may have been due to the relative excess of CP and CL cases. Although congenital defect frequencies are usually lower in population than in hospital-based registries, differences in the proportion of the main OC categories are not expected and are probably due to ICD-10 coding issues, such as lumping of unilateral CL and CL without other specifications. ICD-10 codes, whose deficiency for oral clefts is fully explained in the literature, lack modifiers for severity, or clinical subtypes. This paper shows the practical aspect of the ICD-10 system deficiency in capturing cleft lip and palate (CLP) subtypes, as demonstrated in SINASC covering three million births per year. Such errors are expected to occur in any registry that uses the ICD-10 coding system, and must be adjusted, given its relevance worldwide.
