Motor development of children between 0 and 18 months of age: Differences between sexes
AbstractThe first years of life are fundamental to the acquisition of motor, cognitive, and social skills; thereforethe opportunities provide to the child as well as the social’ exceptive affect the development. The objectiveof this study was to assess and compare the motor development of boys and girls ages from 0to 18 months. Ninety infants, ages from 0 to 18 (45 boys and 45 girls, stratified by age groups), thatlived in the south of Brazil, attending to daycares participated in the present study. The Alberta InfantMotor Scale (AIMS) was used to evaluate motor development. The majority of the infants showed typicaldevelopment (73.3%); no significant differences between the sexes was found for motor developmentfor the AIMS total scores (pesc.total = .76; ppercentil = .38) and postures (pprono = .71; psupino = .49; psentado =.71; pempé = .97; pesc.total = .76; ppercentil = .38); non-significant differences’ for association between motordevelopment and sex were found (Eta² = .008; Eta² = .108). In the two first years of life, boys and girlsdemonstrated similar motor development performance. It is conjectured that the differences betweensexes observed latter is affected by opportunities of the environment.
