Background:

Evaluación del Desarrollo Infantil or Child Development Evaluation (CDE) test, a screening tool designed and validated in Mexico, classifies child development as normal (green) or abnormal (developmental lag or yellow and risk of delay or red). Population-based results of child development level with this tool are not known. The objective of this work was to evaluate the developmental level of children aged 1-59 months living in poverty (PROSPERA program beneficiaries) through application of the CDE test.

Methods:

CDE tests were applied by specifically trained and standardized personnel to children <5 years old who attended primary care facilities for a scheduled appointment for nutrition, growth and development evaluation from November 2013 to May 2014.

Results:

There were 5,527 children aged 1-59 months who were evaluated; 83.8% (n = 4,632) were classified with normal development (green) and 16.2% (n = 895) as abnormal: 11.9% (n = 655) as yellow and 4.3% (n = 240) as red. The proportion of abnormal results was 9.9% in children <1 year of age compared with 20.8% at 4 years old. The most affected areas according to age were language at 2 years (9.35%) and knowledge at 4 years old (11.1%). Gross motor and social areas were more affected in children from rural areas; fine motor skills, language and knowledge were more affected in males.

Conclusions:

The proportion of children with abnormal results is similar to other population-based studies. The highest rate in older children reinforces the need for an early-based intervention. The different pattern of areas affected between urban and rural areas suggests the need for a differentiated intervention.
