Association between Contextual Factors and Affordances in the Home Environment of Infants Exposed to Poverty.

Home environments of infants exposed to poverty exhibit fewer affordances for child development. This study aimed to investigate the association between contextual factors and affordances in the home environments of infants facing poverty. Term infants (n = 128) were divided into two groups: (1) exposed group (EG), comprising term infants exposed to poverty, and (2) comparison group (CG), consisting of term infants classified with medium and high socio-economic status. The main dependent variables were physical space, variety of stimulation, gross and fine motor toys, and the total score; measured using the Brazilian version of the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) questionnaire, named Affordances no Ambiente Domiciliar para o Desenvolvimento Motor-Escala Bebê. Statistical analysis employed independent sample t-tests or Mann-Whitney tests, chi-square tests, and stepwise multiple linear regression models to evaluate predictors of less adequate home environments. The EG presented significantly fewer affordances in gross motor toys (Cohen's r = 0.353; p < 0.01); fine motor toys (Cohen's r = 0.327; p < 0.01); and total score (Cohen's r = 0.377; p < 0.01). Binary logistic regression analysis showed a significant association (r2 = 0.828, p < 0.01) between the less than adequate home environment category and maternal age (p = 0.043, OR: 0.829 (0.692-0.994)), revealing that maternal age was associated with better quantity and quality of affordances for child development.

Parental Practices and Environmental Differences among Infants Living in Upper-Middle and High-Income Countries: A Cross-Sectional Study.

Parental practices and environmental factors can impact a child's development and, consequently, functionality. The objective is to assess the parental practices and environmental differences in healthy and at-risk infants at 3-6 months of age living in upper-middle (Brazil) and high-income (Italy) countries. A total group of 115 infants was identified and classified into four groups: healthy Italian infants (H_IT); Italian infants exposed to biological risk factors (R_IT); healthy Brazilian infants (H_BR); and Brazilian infants exposed to environmental risk factors (L_BR). The dependent variables were parental practices and environmental factors, which were assessed through a semi-structured interview and the "variety of stimulation dimension" from the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) questionnaire. Descriptive analyses, a multivariate analysis of variance (MANOVA), and correlation tests were applied. Regarding the environment and parental practices, the mother's age, maternal and paternal education, civil status, and variety of stimulation showed significant differences among the infants living in Brazil or in Italy. There were strong dissimilarities in parental practices and environmental factors among infants living in low/upper-middle and high-income countries. Since the home environment is the main stimulus for infant growth and development, our results are meaningful for providing knowledge about these two different cultures.
