Objetivo: evaluar condiciones de vida familiares, el estado nutricional y el desarrollo infantil (di) de preescolares de Urabá y explicar los hallazgos según la determinación social de la salud-enfermedad de la Epidemiología Crítica. Metodología: encuesta de prevalencia. Usamos 8 cuestionarios sobre condiciones de vida. Evaluamos indicadores antropométricos calculados con Epinut 6.0 y usamos la prueba tamiz Escala Abreviada de Desarrollo para evaluar el DI. Resultados: se evaluaron 200 familias y 46 niños (2,5-4 años). Las condiciones de vida son muy deficientes en los procesos individualesfamiliares y los procesos grupales (modo de vida). Unos y otros están determinados por el sistema socio-económico, jurídico-político e ideológico-cultural vigente. Los riesgos de desnutrición, evaluados con -1 y -2 desviaciones estándar fueron, respectivamente: crónica 76% y 37%; global 61% y 17%; aguda 26% y 0%. La frecuencia de retardos madurativo y patológico fueron respectivamente: en motricidad gruesa 17% y 6%; en motricidad fina 50% y 26%; en audición-lenguaje 40% y 34%; en desarrollo personal-social 57% y 6%. Ningún coeficiente de desarrollo infantil se asoció con desnutrición crónica. Las altas deficiencias nutricionales y de desarrollo de los niños están lógicamente determinadas por las condiciones de vida de las familias y el grupo social. Conclusiones: los resultados revelan deterioro nutricional y sicomotor profundos precoces. Las condiciones de vida de este grupo social explican la situación hallada. Urge la intervención del Estado para afrontar y paliar tan grave problema colectivo.

Down syndrome (DS) is one of the most common chromosomal abnormalities. Delays in cognitive development are found in the first years of life. As years pass, it may turn into intellectual deficiencies that unfold into several aspects, including difficulty recognizing emotional facial expressions. The present study investigated the recognition of six universal facial emotional expressions in a population of children aged 6-11 years who were divided into two groups: DS group and typically developing children (TDC) group. We used the Perception Test of Facial Emotional Expressions (Teste de Percepção de Emoções Faciais; TEPEF) and Wechsler Intelligence Scale for Children (WISC-III) and found that children with DS presented alterations in the recognition of expressions of disgust, surprise, and fear, whereas the recognition of happiness, sadness, and anger was maintained at a level comparable to the TDC group. Participants with DS presented significant positive correlations between sadness and Picture completion, Mazes, Arithmetic, Vocabulary, Digits, Verbal IQ, Verbal Comprehension Index, and Working Memory Index. All other facial expressions showed significant negative correlations with the Intelligence Quotient and WISC-III factorial index subtests. Absence of correlations was found among the TEPEF's six facial expressions and Information, Coding, Symbols, and Working Memory Index. The contribution of this study is related to understanding the characteristics of the recognition of facial emotions in children with DS, an important component of social relationships with their peers, schools, and families.

Background: This paper aimed to explore the ability of people with Down syndrome (PWDS) in recognizing facial emotion by considering automatic cognitive processing levels of face recognition. Method: A sample of PWDS and participants with typical development (PWTD) participated in a set of two affective priming studies. In each study, participants had to categorize an emotional or neutral target face that was preceded by another emotional face. Stimuli presentation for each facial set (one face after another) was conducted by using an stimulus onset asynchrony (SOA) of 300 ms with the inter-stimulus interval (ISI) set at 50 ms. The first affective priming study manipulated emotion congruency between prime and target emotional faces to explore emotion classification abilities and to identify the cognitive mechanisms underlying automatic recognition of some emotional faces. The second study explored the effect that gender of a face has over categorization of facial emotion and difficulty in recognizing negative facial expressions. Results: The results strongly suggest that not all of the PWDS present difficulties in recognizing negative facial emotions. PWDS' performance pattern in categorizing emotion was similar to that of PWTDs if they had to use broad classification categories (e.g., emotion vs. no emotion). However, differences between both samples occurred if PWDS had to use a specific category task (e.g., classification of happiness, sadness, etc.). Conclusions: At least two emotion information processing styles can be identified in PWDS. Methodological and theoretical implications for exploring the emotional capabilities of people with DS are discussed.
