Desenvolvimento motor, cognição e linguagem em lactentes que frequentam creches

AIMS: To evaluate the acquisition of motor milestones in the first two years of life and the relationship between gross motor function and manipulation, cognition and language in infants who attend day care centers. METHODS: Cross-sectional study with a non-probabilistic sample of infants attending public and private day care centers in a city in southern Brazil. The Alberta Infant Motor Scale and the Bayley Scales of Infant and Toddler Development were used to assess the motor performance of each child. Descriptive statistics were used for the characterization of the sample and simple linear regression in three different age groups (group 1: between six and nine months; group 2: between 10 and 12 months; group 3: between 13 and 16 months) for the analysis of relationships between the variables gross and fine motor skills, cognition and language. RESULTS: We studied 63 infants between six and 16 months of age who did not present statistically significant differences in their biological and sociodemographic characteristics when the three stratified groups were compared. Most children did not acquire the developmental milestones in the period expected for their age group. There was correlation between the developmental scores, and the gross motor function was able to explain a large part of the variability in the fine motor function, cognition and language scores (R 2 ajust>0.5) over the first two years of life. CONCLUSIONS: The evaluated motor skills occurred generally late in the sample. The delay in the acquisition of gross motor milestones had an impact on the overall developmental skills, corroborating the influence of gross motor function in the other domains of development.

Cognición y ambiente son predictores del desarrollo motor de bebés a lo largo del tiempo

We conducted a longitudinal investigation on the relationships among motor and cognitive development, biological aspects, maternal practices, parental knowledge, and family environments of infants. Forty-nine infants aged between 3 and 16 months participated in the study. They were evaluated through the Alberta Infant Motor Scale and the Cognitive Scale of the Bayley Scales of Infant Development. Their parents answered a questionnaire about biological factors, the Daily Activities of Infant Scale, affordances for motor development (Baby Scale) in the home environment, and the Brazilian version of the Knowledge of Infant Development Inventory. We conducted evaluations in schools for 4 months. Generalized estimating equations, Bonferroni correction, and Spearmans rank correlation coefficient were used. Significant associations were found in the (1) univariate analysis between motor and cognitive development and environmental factors (education level, income, toy availability, physical space, parental practices and knowledge, breastfeeding duration, and school frequency); (2) multivariate analyses between motor development and income, and between fathers age and physical space at home. Motor and cognitive developments were concluded to depend on each other, and environmental factors were shown to be more significant in the associations rather than the biological ones, stressing the importance of home, of parental care, and of the experiences children go through along the first years of their lives.Se investigo longitudinalmente relaciones entre desarrollo motor y cognitivo, aspectos biologicos, practicas maternas, conocimiento parental y ambiente familiar de bebes. Participaron del estudio 49 bebes (3-16 meses) evaluados con la Alberta Infant Motor Scale y la Escala Mental da Bayley Scale of Infant Development. Los padres respondieron al cuestionario sobre factores biologicos Daily Activities of Infant Scale, el Affordance en el Ambiente Domiciliario para el Desarrollo Motor - Escala Bebe, y el Inventario sobre Conocimiento del Desarrollo Infantil. Se condujeron evaluaciones en las escuelas a lo largo de 4 meses. Se utilizaron Ecuaciones de Estimativa Generalizada, prueba de Bonferroni y coeficiente de correlacion de Spearman. Se observo asociaciones significativas en la (1) analisis univariada entre desarrollo motor y cognitivo y factores ambientales (escolaridad, renta, disponibilidad de juguetes, espacio fisico, practicas y conocimiento parental, tiempo de amamantamiento y frecuencia en la escuela); (2) multivariada entre el desarrollo motor y renta, edad del padre y espacio fisico de la residencia. Se concluye que los desarrollos motores y cognitivos se mostraron interdependientes y factores ambientales se mostraron mas significativos en las asociaciones debido a los factores biologicos, se reforzando la idea de la importancia del hogar, del cuidado de los padres y de las experiencias que el nino vive a lo largo de sus primeros anos de vida.
