Geographic regional distribution of prevalence of low birth weight in Peru
Dear. Editor
Low birth weight (LBW) continuous to be a global public health problem and it is an important health indicator that identifies the social, economic, and environmental background of the newborn and his family, determined when the birth weight is less than 2500 grams .1-2In Peru, this indicator is evaluated annually through the Encuesta Demográfica y de Salud Familiar (ENDES). The Ministry of Health of Peru (MINSA) and the Registro Nacional de Identidad y Estado Civil (RENIEC) developed and began the implementation in 2012 of the Certificado de Nacido Vivo en Línea (CNV). This system allows the registration of newborns and generates a real-time birth certificate, also records information such as gender, weight, height, characteristics of gestation and childbirth, among other nominal health variables, this system is free of charge and use by the public and private Health Care Institutions (IPRESS).3
The objective of this communication is to show the spatial distribution of the regional prevalence in Peru of LBW reported by ENDES and CNV for the year 2018. An analysis was made of the information reported by the CNV, which originates from the nominal register of health care in the IPRESS where births were attended by health personnel. The ENDES whose information is collected from health cards or information reported by the mother in the interviews conducted, although their results are referential because of its high coefficient of variation has continuity in their reports for more than a decade. The existing statistical differences were compared with the prevalence reported by the ENDES and the CNV and categorization were made into three groups according to the differences between the two sources of information.
We evaluated 494,024 records of newborns reported to the CNV for 2018 with full information to establish the prevalence of LBW and carry out the spatial distribution .4We observed a difference in the national prevalence of LBW of 1.3% in comparison with the ENDES of the same year, at the regional level we have that the group with the greatest difference (between 2.4% to 3.4%) were found Ica, Pasco, Amazonas, Junín, Madre de Dios, Lima Provinces, Moquegua and Loreto. The group with a different intermediate (between 1.3% to 1.8%) are Huánuco, Lima, Ucayali, Tumbes, Arequipa, and La Libertad. Finally, the group with a different minimum (between 0% to 1.1%) are located in Cusco, Callao, San Martín, Tacna, Ancash, Ayacucho, Puno, Piura, Cajamarca, Apurimac, Huancavelica, and Lambayeque. The differences found to show that all cases were less than ±3.5% between CNV and ENDES (Figure 1), all reported values agree with global estimates (14.6%) and for Latin America and the Caribbean (8.7%)(1), It evidences the importance of having nominated health information systems that allow accurate population health interventions .5
The CNV has been closing coverage gaps, according to the projection of births of the Instituto Nacional de Estadística e Informática (INEI), the CNV had 12.4% coverage among registered births for the year 2012, with an increasing trend over time and achieving 88.1% coverage for the year 20184, The CNV has been closing coverage gaps, according to the projection of births of the Instituto Nacional de Estadística e Informática (INEI), the CNV had 12.4% coverage among registered births for the year 2012, with an increasing trend over time and achieving 88.1% coverage for the year 20186. The difference highlights the ENDES that only gives us reference information at the regional level for the indicator of LBW7, e), the system CNV allows us to count with nominal data to track each child and allows that the Integrated Health Network Addresses (DIRIS) at the national level to coordinate health interventions with their regional and local authorities, the MINSA should continue to strengthen the systems of nominated information being implemented at the national level.6,8
En conclusión, el 6.0%4of newborns reported by the CNV have LBW compared to 7.3%6qreported by ENDES for 2018, 12 of the 26 spatial distribution have a difference of less than 1.1% between both sources of information. The CNV provides nominated information for follow-up interventions at the population level and to help improve the health of mothers and newborns.
