Abstract
This study examined the influence of prenatal, perinatal, and postnatal factors on early motor development, comparing clinical, environmental, and cumulative risks among children of adolescent and adult mothers in Brazil. The aim was to generate evidence to guide interventions that improve maternal and child health outcomes.
Methods
This cross-sectional study included 662 infants (176 preterm; 486 full-term) and their mothers (140 adolescents; 522 adults) from 17 cities across Brazil. Infants aged 0–4 months were consecutively recruited, and those with musculoskeletal disorders, genetic syndromes, or congenital malformations were excluded. The motor development was assessed with the Alberta Infant Motor Scale (AIMS), the home affordances with the AHEMD-IS, and maternal knowledge with the KIDI. Assessments were conducted in hospitals, clinics, or home setting. Statistical analyses included ANOVA, Pearson correlations, Chi-square, and backward regression. Inter- and intra-rater reliability form motor assessments was high (α =.99 and α =.97, respectively). Ethical approval and informed consent were obtained.
Results
Infants of adolescent mothers had lower birth weights and head circumferences and were exposed to more environmental risks. Adolescent mothers showed lower education, income, and knowledge of infant development and provided fewer motor developmental opportunities. Motor scores were positively associated with birth outcomes, breastfeeding, and maternal education. Regression analysis identified breastfeeding and gestational age as the strongest predictors of motor development. Higher cumulative prenatal, perinatal, and postnatal risks were linked to poorer motor performance.
Conclusion
These findings underscored the combined influence of biological and socio-environmental factors on early motor development and highlight the need for early interventions and integrated policies to reduce health disparities and support children of adolescent mothers.
期刊介绍:
Infant Behavior & Development publishes empirical (fundamental and clinical), theoretical, methodological and review papers. Brief reports dealing with behavioral development during infancy (up to 3 years) will also be considered. Papers of an inter- and multidisciplinary nature, for example neuroscience, non-linear dynamics and modelling approaches, are particularly encouraged. Areas covered by the journal include cognitive development, emotional development, perception, perception-action coupling, motor development and socialisation.
