**Abstract**

The neurodevelopment screening test Valoración Neuroconductual del Lactante (VANEDELA's) allows the professional to follow the rapid and economic application development in which high- and moderate-risk children who do not reach their optimum development potential during the first 2 years of life can be detected in a timely manner. It also provides a tracking tool to follow-up the recommendations and interventions of children who had developmental delays to see how adaptive strategies work.

### **1. Introduction**

Infant tracking is one of the important services in pediatrics, as there are different risk factors that affect the structure or those that are the product of parenting either by default or oversolving their needs without allowing the child to explore and participate in the construction of their competences, which are children without any organic pathology; however, they are delayed in development, as we will see later, leaving them unattended until the problem becomes apparent, given that the current health model focuses on the detection of children at risk of disability, escaping or belatedly detecting alterations in growth and development. World Health Organization (WHO) reported in 2010 that 249.4 million (43%) children under the age of 5 in the world and 9.7 million (18%) in Latin America and Caribbean presented risks of not reaching their development potential for various causes such as poverty, poor nutrition, unresponsive care and others. In addition, many research in the open population in Mexico reported figures of 40% of children with mild and moderate delays [1–3]. Mexico's cases are reported and recorded in which the sequel is clearly established, the technique "wait and see" issued, waiting for the infant to solve the problem or to structure the disability through maturation, being late his attention. For example of this is parents who come and go with their children, reporting to health personnel observations of behaviors that do not perform or make them different to other children of the same age, because having no early referrals tend to leave ample waiting times if provide an adequate solution to

the patient and the family, which causes the delay [4–6] to increase and adequate solutions to the patient and the family, which causes the delay to increase.

gives normal when they present the reactions that are evaluated at the age cohort, slight risk to find any of the reactions evaluated that are still in process, and risk of alteration when the expected reaction does not occur or is accompanied by signs. It is necessary to emphasize the reactions of the development, allow the infant to organize the different movement patterns, and reach the bipedal posture and move. In order to analyze the importance of early monitoring of infants, the first 2 years of life optimize their development. In a study conducted in newborns and infants from 2011 to 2014, in the Neurodevelopment Monitoring Laboratory in National Institute of Pediatrics and the Tlalpan Family Medicine Clinic, ISSSTE, parents accepted and signed the informed consent letter. The VANEDELA's test was applied to determine the behaviors that were being constructed as part of the research "*Acquisition ages in Mexican infants of the evolutionary sequences of the white behaviors of the VANEDELA's screening test*" approved by the Research Commissions and Ethics of the National Institute of Pediatrics (Registration

The average age of the mothers was 29.32 5.43 years, with a minimum age of 16 and a maximum age of 43 years; average age of the father was 33.37 6.80 years, with a minimum age of 20 and a maximum age of 53 years. With medium to professional studies and that one of the parents had a stable job, the Gini's coefficient of 0.1292 was obtained, which places them as a population with an adequate

With this follow-up, we observed that children can present some obstacles in the process of building different competences in the course of development both without and with perinatal risk [16]. According with the instrument, we have 202 infants from 1 to 24 months, follow the trajectory expected, 127 perform behaviors among 9–8 of the proposals, here we could be seeing both children if perinatal risk or infants at risk who are in follow-up are building the various skills and 113 are at

The relation, the three-risk group and the score obtained in the format of developmental behaviors and developmental reactions is significant when analyzing the relationship for each group the low-moderate risk relationship in development reactions does not show significant difference what is if the alterations in the development reactions will be delayed when neurological damage occurs, however, after 8 months, we observe that the difference between low and high risk, probably the reactions of actively rolling and protection to the front, is not significant, they

In the analyze, by month to cohort and month the children (a) of low risk presents a proportion of realization between (1) and (0.92); those of moderate risk between (1) and (0.60), making the reagents of visual tracking 45° on each side difficult, try to raise the head, activating the muscles of the neck, although the labyrinthine optical reflex is present and the flexion of prone members, possibly some of these children presented low tone; high-risk infants are between (0.36) and (0.93), where the behaviors that occur most often are heard the sound of the rattle

(51%) boys and 218 (49%) girls were distributed by gender. According to their performance in the EEC Gesell's development test [15], three low risk groups were configured, which are children who did not present perinatal risk and their performance is as expected. Moderate risk those children who does not present perinatal risk; but a minor problem such as allergy or problems of upbringing or a performance lower than 85. But greater than 76 and high risk those who presented perinatal risk as at birth congenital heart disease, congenital hypothyroidism, premature infants, perinatal asphyxia, and epilepsy who attended mainly to the

perinatal risk that will have scores of 7 or less.

The protective factors are intimately linked to organizational possibilities and stimulating variability that allow the child to explore and interpret, creating categories of greater complexity, integrating motor, cognitive, communication, emotional interaction, social interaction, and self-care [7, 8]. Faced with this problem, screening instruments allow timely detection of children who present obstacles at different times in the first years of life, as well as being a useful and quick tool to follow-up [9–11]. "Valoración Neuroconductual del Lactante" (VANEDELA) is a Mexican sieve test with sensitivity (79–89%) and specificity (83–95%) [12]. In order to detect early infants at risk for sequelae at the first level of care, six cohorts of ages 1, 4, 8, 12, 18, and 24 months (M) are evaluated, with white-indicators, which children with delays do not perform at the proposed age. The instrument consists of three formats and somatometry is taken into account [13]. For this chapter, the formats of developmental behaviors (CDs) and developmental reactions (RDs) were analyzed in infants.

## **2. Development behaviors format (CD)**

It consists of 60 behaviors that are grouped in different areas of development such as feeding, gross and fine motor, receptive and expressive language, cognitive development. The evaluation sheet is presented in six cohorts of ages 1, 4, 8, 12, 18, and 24 months; each cut includes 10 reagents, which qualifies a positive point when the observation or negative reference is met if performing qualitatively prior to that requested, the final score considers risk-free when the child gets 10 points, mild risk 9–8, and risk of alteration 7 or fewer points.

Correlation data were obtained from Pearson and Student's t-test to assess the difference between mean and rating groups in behaviors and reactions of developmental will be used at J MP 8 statistical software.

### **3. Reactions of development format (RD)**

A total of 10 reactions divided into 3 groups are evaluated according to their evolution: four are straightening reactions, three defense, and three balance. The evaluation sheet is presented in cohort of age. The first month evaluates the reaction of optical, labyrinth, and head straightening acting on the body; Landau reflux in 4 months; straightening of the body and sitting lateral defense in 8 months; the reaction of defense forward and defense sitting back in 12 months; the sitting equilibrium reaction at four points by 18 months; and the equilibrium reaction stopped in 24 months.
