Introduction:

Adequate psychomotor development during the first years of life significantly impacts the growth of each infant, so the timely detection of risk factors that affect this development is of vital importance. The objective was to determine sociodemographic and maternal factors associated with the presentation of psychomotor retardation in infants under two years old who attended the Centro de Rehabilitación y Educación Especial in Villahermosa (Tabasco, Mexico) in 2017.

Materials and methods:

An observational, retrospective study of cases and controls in infants under two years old. Data collection was performed using a questionnaire consisting of 45 questions, which included variables such as psychomotor retardation, prenatal, perinatal, and postnatal risk factors, that used Pearson's chi-square test and Fisher's exact test, with a significant correlation of p <.05 being accepted .

Results:

A low social class showed a significant relationship with psychomotor retardation (p =.000), while the presence of infections at a very young age in the newborn, a family history of psychomotor retardation, and a history of disease during pregnancy showed a value of p <.05.

Conclusión:

A low socioeconomic status, pregnancy-associated diseases such as malnutrition, high blood pressure, and traumatic accidents, as well as infectious diseases at birth were the main factors that conditioned psychomotor retardation.
