Parent-Guided Developmental Intervention for Infants With Very Low Birth Weight: A Randomized Clinical Trial

Importance

Early interventions improve neurodevelopmental outcomes after preterm birth, but few studies of early intervention have focused on preterm infants whose families reside in low- or middle-income countries (LMICs).

Objective

To evaluate whether parent-guided early intervention improves the neurodevelopmental outcomes of preterm infants in an LMIC.

Design, Setting, and Participants

This randomized clinical trial was performed at a high-risk obstetric referral hospital in Brazil, with outcome evaluations by examiners masked to randomization group. Eligibility criteria were (1) birth at the study hospital, (2) residence within 40 km of the birth hospital, and (3) gestational age of less than 32 weeks or birth weight of less than 1500 g. Of 138 enrolled infants, 19 died after randomization and 19 withdrew from the study; all other enrollees (50 per randomization group) were evaluated for the primary outcome. Data were collected from January 1, 2016, to May 31, 2022, and analyzed from June 10 to July 31, 2022.

Interventions

On postnatal day 7, infants were randomized to usual care, consisting of support for lactation, kangaroo care, and routine developmental therapies, or to a parent-guided enhanced developmental intervention, consisting of usual care plus infant massage and enhanced visual stimulation, auditory stimulation, social interactions, and support for motor development, instructed by developmental therapists.

Main Outcomes and Measures

The primary outcome was the Bayley Scales of Infant and Toddler Development-Third Edition score at 18 months of age adjusted for prematurity.

Results

Among the 100 infants included in the analysis, mean (SD) gestational age was 28.4 (2.2) weeks, and 57 (57%) were male. The mean (SD) gestational age for the intervention group was 28.3 (2.3) weeks; for the usual care group, 28.5 (2.2) weeks. Female infants accounted for 21 infants (42%) of the intervention group and 22 (44%) of the usual care group; male infants, 29 (58%) and 28 (56%), respectively. The enhanced developmental intervention group had higher cognitive scores at 18 months of corrected age (mean [SD], 101.8 [11.9] vs 97.3 [13.5]; mean difference, 4.5 [95% CI, 0.1-8.9]).

Conclusions and Relevance

In this randomized clinical trial of a parent-guided developmental intervention for early cognitive function of very preterm or very low birth weight infants implemented in an LMIC, the intervention improved very preterm infants' neurodevelopmental outcomes at 18 months of adjusted age. Parent-guided early intervention can improve neurodevelopmental outcome of very preterm infants born in LMICs.

The relationship between home environment affordances and motor development and sensory processing skills in premature infants

The availability of stimulating materials in the home environment is of great importance to optimizing an infant's development. This study, which has a cross-sectional study design, was conducted to examine the relationship between home environment conditions and equipment support and the motor development and sensory processing skills of premature infants. Children born premature, aged 10-16 months, were included in the study. Motor development was evaluated with the Peabody Motor Development Scale-2, and sensory processing skills were evaluated with the Test of Sensory Function in Infants. The Affordances in the Home Environment for Motor Development-Infant Scale was used to evaluate the home environment. A total of 51 premature infants were included in the study. It was determined that there was a significant relationship between physical space, stimulus variety and fine motor toys in the home environment and Peabody Motor Development Scale-2 gross motor and fine motor development scores. It was also shown that there was a relationship between the tactile and total scores of the Test of Sensory Function in Infants Scale and the variety of stimuli in the home environment and gross motor toy scores. These findings show that the opportunities provided in the home environment of premature infants may be related to their motor development and sensory processing skills. Consequently, the home environment may be associated with experiencing movements and sensory experiences.

Association between environmental factors during the COVID-19 pandemic and functioning of infants with biological risk in the first year of life: Cross-sectional exploratory study

BACKGROUND

Child development can be influenced by family and environmental factors, which changed during the COVID-19 pandemic. Thus, it is important to explore how these factors are associated with the functioning of infants with biological risk in the first year of life.

OBJECTIVE

This study aimed to investigate associations between family factors, home opportunities, caregiver perception of environmental support and barriers at home and environmental factors during the COVID-19 pandemic and gross motor skills and home participation in infants with biological risk in the first year of life.

METHODS

Fifty-six infants aged two to 12 months (M = 5.80 months; ±2.44) and their mothers performed remote assessments of gross motor skills using the Alberta Infant Motor Scale (AIMS); participation and environment (phone call) by the Young Children's Participation and Environment Measure (YC-PEM); family factors (income, age and maternal education), home opportunities - The Affordances in the Home Environment for Motor Development - Infant Scale (AHEMD-IS) and environmental factors during the COVID-19 pandemic (social distancing, emotional and financial factors and physiotherapy) (online forms). Regression models were constructed, considering gross motor skills and home participation as outcome variables, with a 5 % significance level.

RESULTS

We found that older maternal age (p = 0.001), more home opportunities (p = 0.043), and less rigorous social distancing (as opposed to total social distancing [p = 0.045]) were significantly associated with better gross motor skills; and higher maternal education (p = 0.050) was associated with more involvement in home activities.

CONCLUSION

Family factors, home opportunities and social distancing were differently associated with the gross motor skills and home participation of infants with biological risk in the first year of life.

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.

Gross motor trajectories of pre-term and full-term infants under different parental educational approaches

This study aimed to explore motor trajectories of Brazilian pre-term and full-term infants from 3 to 12 months old whose parents participated in an educational program and had received guidance on gross motor development. Forty-eight Brazilian infants aged 3 months old were divided into Group 1 (full-term infants and their parents who received only verbal guidance, n = 14), Group 2 (full-term infants with parents who received an educative folder in addition to the same verbal guidance, n = 23), and Group 3 (preterm infants with parents who received the same verbal guidance and educative folder, n = 11). The folder had similar information to the verbal guidance; nonetheless, it helped to teach parents and allowed later consultation at home. We applied Alberta Infant Motor Scale, Affordances in Home Environment for Motor Development-Infant Scale, and a questionnaire about infants' information at 3-, 6-, 9-, and 12-months old. In longitudinal comparison, all groups showed a significant difference for AIMS variables on total score and subscales; all subitems of AHEMD-IS; and time spent in prone, supine, sitting, and standing positions. In general, no differences were found between groups. Motor trajectory, home opportunities, and parental positioning practices were similar between full-term and preterm infants with different guidance approaches.

Mom Didn't Go to School, Dad Is Out of Work: Associations between Maternal Educational Attainment, Family Socioeconomic Status, and Infant Development

The purpose of this research is to assess the neuropsychomotor development (NPMD) of 6- to 18-month-old infants and identify factors that may pose a risk to their development. They underwent NPMD assessments, while the parents/guardians were interviewed through the other instruments. Altogether, 64 infants participated in this research. The results revealed infants with questionable NPMD: 29.7% verified with AIMS and 32.8%, with Denver II. There were significant associations between NPMD and maternal low educational attainment (P = .032); family low socioeconomic status and NPMD (P = .026), verified with AIMS and Denver II (P = .037); stimulation opportunities at home and maternal low educational attainment (P = .00026), socioeconomic status (P = .035), and NPMD, verified with AIMS (P = .02) and Denver II (P = .009). The following were identified as risk factors for NPMD: maternal low educational attainment (the lower her attainment, the more likely for the NPMD to be questionable) and family socioeconomic status (infants from disadvantaged homes tend to have questionable NPMD). Stimulation opportunities at home were also significantly associated with NPMD-that is, insufficient stimulations at home may lead to questionable NPMD.

Affordances in the home environment of children at risk of developmental delay

OBJECTIVE

The aim of this study was to verify the adequacy of affordances in the home environment of children at risk of developmental delay and to identify factors associated with their frequency.

METHODS

The cross-sectional study included 97 families who responded to the Affordances in the Home Environment for Motor Development - Infant Scale (AHEMD-IS) for 3-18 months (n=63), or AHEMD - Self-Report (AHEMD-SR) for 18-42 months (n=34). The Mann-Whitney U test was used to identify the differences between the frequencies of affordances between the groups. Multiple linear regression was used to verify the association between the child's sex, mother's marital status, education, socioeconomic level, child and mother's ages, house residents' number, per capita income, and AHEMD scores (α=0.05).

RESULTS

The home affordances' frequency in the AHEMD-IS ranged from less than adequate to excellent, while in the AHEMD-SR, the highest predominance was medium. The offer of stimuli in the AHEMD-IS was significantly higher. Higher socioeconomic level and house residents' number were associated with greater affordances.

CONCLUSIONS

The higher the socioeconomic level and house residents' number, the greater the affordances in the homes of children at risk of delay. It is necessary to provide families with some alternatives to make their home environments richer in affordances that favor child development.

Assessment of the neuropsychomotor development of HIV-exposed infants using the ICF model

ABSTRACT This study aimed to systematize and build a checklist with tools to assess child development according to the biopsychosocial model of the International Classification of Functioning, Disability, and Health (ICF) of infants exposed to HIV, aged from 4 to 12 months. This is an observational, analytical, and longitudinal study. Bayley-III Scale of Infant and Toddler Development; Affordances in the Home Environment for Motor Development-Infant Scale; Brazilian Criteria of Economic Classification; and infant’s history used in the assessment were described according to the ICF domain categories. The tools used in this study include the components of body structure and functions; activities and participation; environmental and personal factors. The description of the assessment tools in the child development of infants exposed to HIV-by the constructs and domains of the ICF-allowed for the construction of clinical reasoning during the assessment, emphasizing the surveillance of child development and functioning in their first year of life.

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.

Fisioterapia com brinquedos e terapia assistida por cães em lactentes: estudo observacional

RESUMO O objetivo deste trabalho foi comparar a fisioterapia com brinquedos com a terapia assistida por cães no desenvolvimento neuromotor de lactentes de quatro meses de idade com e sem alterações neuromotoras. Trata-se de pesquisa descritiva e observacional de caráter qualitativo, realizada com 10 lactentes, que foram avaliados pela escala motora infantil de Alberta (EMIA), divididos em grupo 1 (G1) e grupo 2 (G1) e subdivididos em grupo brinquedo (G1B e G2B) e grupo cão (G1C e G2C) para a realização das intervenções quinzenais. O questionário Affordances in the Home Environment for Motor Development - Infant Scale (AHEMD-IS) foi escolhido para avaliar as oportunidades presentes no ambiente domiciliar. A análise de dados qualitativos foi feita por meio de fotos e filmagens. A presença do cão nos grupos G1C e G2C resultou em um ambiente descontraído e divertido, interesse dos lactentes em tocar o pelo do animal, movimentos alternados de membros, contato visual, emissão de sons, evolução na interação social e sentimento de segurança. Nos grupos G1B e G2B, constatou-se diminuição da motivação, ausência de emissão de sons pelos lactentes e contato visual e interesse pelo toque restrito a brinquedos que tivessem diversas cores e sons, havendo pouca agitação e motivação para as habilidades motoras nesses grupos. Conclui-se que a presença do cão promoveu melhores resultados motores, sociais, afetivos e cognitivos. A terapia assistida por animais pode ser um método eficaz para auxiliar na fisioterapia convencional de lactentes com atraso no desenvolvimento neuropsicomotor.

A qualidade do ambiente domiciliar influencia nas habilidades funcionais de crianças na primeiríssima infância?

RESUMO A literatura extensamente associa o desenvolvimento infantil à qualidade da estimulação ambiental. Entretanto, são escassos os estudos que verificam se tal associação tem relação com as habilidades funcionais da criança. Este estudo tem por objetivo investigar quais oportunidades no ambiente domiciliar estão associadas e explicam às habilidades funcionais de mobilidade e função social de crianças na primeiríssima infância. Trata-se de um estudo transversal e exploratório feito com 74 crianças entre 6 e 18 meses. Para avaliar as oportunidades presentes no ambiente domiciliar, foi utilizado o instrumento affordances in the home environment motor development - infant scale. Para avaliar as habilidades funcionais das crianças, foi utilizado o inventário de avaliação pediátrica de incapacidade. Observou-se que a mobilidade das crianças pode ser explicada em 45,6% (R² ajustado=0,45) e a função social em 30% (R² ajustado=0,30) pela quantidade de brinquedos de motricidade grossa, pelos equipamentos e pela variedade de estimulação presente no ambiente domiciliar. Conclui-se que posições, brinquedos e materiais que mantêm a criança mais restrita e menos ativa exercem influência negativa. Por outro lado, brinquedos que oportunizam um maior deslocamento e interação favorecem as habilidades funcionais de mobilidade e função social.

Does the quality of the home environment influence the functional abilities of infants in early childhood?

ABSTRACT The literature associates child development with the quality of the environment stimulation. However, few studies verify if this is associated with the infant’s functional abilities. This study aims to assess which opportunities in the home environment are associated with functional mobility skills and social function of infants in early childhood and explain them. This is a cross-sectional and exploratory study with 74 infants aged from six to 18 months. The affordances in the home environment motor development - infant scale instrument was used to evaluate the opportunities in the home environment. The pediatric evaluation of disability inventory was used to assess the infants’ functional abilities. We observed that infants’ mobility can be explained in 45.6% (Adjusted R²=0.45) and social function in 30% (Adjusted R²=0.30) by the amount of gross motor skills toys, equipment and variety of stimulation in the home environment. We concluded that positions, toys, and materials that keep the infant more restricted and less active have a negative effect. On the other hand, toys that offer greater displacement and interaction favor the functional mobility skills and social function.

Physical therapy with toys and dog-assisted therapy in infants: observational study

ABSTRACT This study aimed to compare physical therapy with toys with dog-assisted therapy in the neuromotor development of 4-month-old infants with and without neuromotor alterations. This is a qualitative descriptive and observational study carried out with 10 infants, who were evaluated by the Alberta Infant Motor Scale, divided into Group 1 (G1) and Group 2 (G1), and subdivided into Toy Group (TG1 and TG2) and Dog Group (DG1 and DG2) for the performance of fortnightly interventions. By the Affordances in the Home Environment for Motor Development - Infant Scale, we assessed the opportunities present in the home environment. Qualitative data were analyzed using photos and videos. The presence of a dog in DG1 and DG2 resulted in a relaxed and fun environment, infants interested in touching the animal’s fur, alternating limb movements, eye contact, sound production, increased social interaction, and feeling of security. In TG1 and TG2, decrease in motivation was observed as well as the absence of sound production and eye contact by infants, and interest in touch restricted to toys that had different colors and sounds, with little agitation and motivation for motor skills in those groups. We concluded that the dog’s presence promoted better motor, social, affective, and cognitive results. Animal-assisted therapy can be an effective method to support conventional physical therapy for infants with delayed neuropsychomotor development.

The home environment and its relation to vocalizations in the first year of life

Background

Prior data has shown that the home environment impacts child development; however, there remains a paucity of research on how the home environment relates to child and adult words. Therefore, the aim of this prospective and quantitative study was to examine the relationship between the home environment and the quantity of vocalizations or words, and conversational turns produced by infants and parents at 3 and 12 months of age.

Methods

Seventy-two (56% male) full-term infants were assessed at 3 and 12 months of age. The home environment was assessed in person via interview and observation of the child's home using the Infant-Toddler Home Observation for Measurement of the Environment (IT-HOME) Inventory subscales. Vocalizations were measured using the Language Environment Analysis (LENA) device, which measures the adult word count, child vocalization count and conversational turn count. These measures were then averaged for the most voluble, or vocal hour, in the recording period.

Results

At 3 months, IT-HOME Learning Materials scores were significantly associated with a decrease in adult words. We found a statistically significant difference in LENA outcomes between 3 and 12 months when stratified by sex. Specifically, male infants had significantly fewer vocalizations at 12 months when compared to 3 months, whereas females had more vocalizations. There was also a statistically significant difference in IT-HOME Learning Materials, Organization, Responsivity, and Total scores when comparing 3- and 12-month time points.

Conclusions

These findings reveal that the home environment changes significantly over the first year of life. At 3 months, Learning Materials in the home were related to adult words, while between 3 and 12 months, several aspects of the home significantly changed. Male children had reduced vocalizations between 3 and 12 months; whereas, female children had increased vocalizations during the same time points. Future research should focus on examining these outcomes with multiple measures, time points, and patient populations.

Responsive Caregiving and Opportunities for Early Learning Associated With Infant Development: Results From a Prospective Birth Cohort in China

BACKGROUND

Infant development shapes children's health into adulthood. Although providing responsive caregiving and opportunities regarding early learning for infants have received increasing attention from the international community, few studies have been published on these topics thus far. The purpose of the present study, then, was to explore the influences of responsive caregiving and the opportunities for early learning on infant development.

METHODS

Mother-child dyads (3,714 pairs) were recruited from the Shanghai Maternal-Child Pairs Cohort (Shanghai MCPC) for the present study, and the development of infants, responsive caregiving and opportunities for early learning were collected from three waves of follow-up (2-, 6-, and 12-month old) We used the cross-lagged model to analyze the longitudinal correlation between responsive caregiving or opportunities for early learning and development of infants. We used the generalized estimation equation (GEE) to evaluate the effect of responsive caregiving and opportunities for early learning on suspected developmental delay; we also conducted a hierarchical analysis to investigate the interaction between responsive caregiving or opportunities for early learning and annual family income.

RESULTS

There was a mutual prediction between responsive caregiving or opportunities for early learning and some developmental domains of the Ages and Stages Questionnaires, third edition (ASQ-3). Sustained high-exposure to responsive caregiving or opportunities for early learning significantly decreased the risk of suspected developmental delay in most domains of the ASQ-3. And For infants whose annual family income was < ¥200,000, sustained high-exposure (Adjusted Odds Ratio = 0.456, 95% CI, 0.325-0.638) and fluctuating-exposure (Adjusted Odds Ratio = 0.510, 95% CI, 0.414-0.627) to responsive caregiving significantly reduced the risk for suspected developmental delay.

CONCLUSION

Responsive caregiving or opportunities for early learning interacted with infant development. Infants' early access to adequate responsive caregiving and opportunities for early learning exerted a sustained and positive impact on infant development, and this effect is more pronounced in relative low-income families.

Association between the home environment and development among 3- to 11-month infants in Shanghai, China

BACKGROUND

Literature highlighted the home environment as a major factor influencing the overall development of children. However, minimal information is available about the home environment in China and especially in small infants. This survey was conducted to find out the association between the home environment and the early development of infants.

METHODS

A total of 1850 infants aged 3-11 months were randomly selected during December 2014 to September 2015. Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) was used to measure the home environment considering the availability of toys, physical space and variety of stimulation. The Age and Stage Questionnaire-Chinese (ASQ-C) was used to measure potential developmental delays among infants. Bivariate logistic regression model was used to test the association between home environment and potential developmental delays.

RESULTS

The percentages of infants with insufficient activity space ranged from 25.27% to 30.23%. With the increase of age, the number of toys available to infants was also increasing. However, varieties of stimulation were decreasing. Compared with infants who have sufficient physical space, the risk of problem-solving development delay increased 26.0% (OR = 0.74, 95% CI: 0.56, 0.97). The risk of gross motor delay was 47.0% (OR = 0.53, 95% CI: 0.53, 0.99) lower in infants with sufficient variety of stimulation than infants without. Fine-motor toys were associated with all domains in ASQ-C except communication development, while gross motor toys mainly affected fine motor and problem-solving development.

CONCLUSION

Positive associations between home environment and development among 3- to 11-month infants in Shanghai, China, were revealed in the current study. The results from the study are expected to be useful for early childhood caretakers, public health practitioners and other professionals to plan interventions, especially for low-income families living in a disadvantaged environment.

Reaching skills in six-month-old infants at environmental and biological risk

OBJECTIVES

To assess kinematic parameters and proximal and distal reaching adjustments of infants at biological or environmental risk and compare with reaching performance of six-month-old full-term infants without known risk factors.

METHODS

This blinded cross-sectional study included 62 infants at six months of age divided into three independent groups: Group with no known risk factor (NRF), 28 full-terms with no risk factors; Low SES group (LSES):19 full-terms classified as low socioeconomic status and no biological risk; Very preterm group (VPT), 15 very preterm infants at six months corrected age and no environmental risk. Infants were placed in a reclined baby chair at 45°, and a malleable and unfamiliar object was presented to the infant at 5-second intervals to elicit reaching movements.

RESULTS

Infants from LSES presented reaching duration (p = 0.032, Cohen's f = 0.349) and movement unit (p = 0.033, Cohen's f = 0.351) significantly higher than VPT group. Horizontal hand orientation was moderately associated with infants at environmental risk (p = 0.031; Cramer's V = 0.30).

CONCLUSION

Infants of low socioeconomic status perform less functional reaching movements than very preterm infants at six months corrected age. Socioeconomic status may impact more on reaching skills than biological risk. Given the importance of reaching for infant development, low-cost public health strategies are needed to identify possible delays.

Home environment opportunities and motor development of infants in the first year

Abstract Introduction: The home environment is a fundamental agent for infant development in the first year of life. Objective: To evaluate the opportunities for environmental stimulation and the motor development of infants at 3, 6, 9, and 12 months of age and determine the association between these opportunities and the parents’ schooling and economic levels, at each age studied. Methods: This is a longitudinal study using the Alberta Infant Motor Scale (AIMS) to assess motor development, the Affordances in the Home Environment for Motor Development - Infant Scale (AHEMD-IS) questionnaire to assess the stimulation opportunities at home, and the Brazilian Association of Research Companies (ABEP) questionnaire to classify the economic level of the families. The association between opportunities for environmental stimulation and schooling and economic levels was determined by the chi-squared test. Results: Thirty-seven infants participated, 54.1% of whom were boys. At 3 months of age, the opportunities for environmental stimulation were unsatisfactory, while at 6, 9, and 12 months satisfactory opportunities predominated. Three infants scored below 10% on the AIMS at 3 months of age, indicating delayed motor development. There was a significant association between economic level and total AHEMD-IS score (p = 0.031), and the toy dimension for gross (p = 0.016) and fine (p = 0.043) motor skills. Conclusion: The infants’ home environment did not provide sufficient opportunities for stimulation in the first months, but improved during the first year. Motor development was considered delayed for three infants, but was suitable in subsequent evaluations.

Cognitive, language and motor development of infants exposed to risk and protective factors

INTRODUCTION

Risk factors are biological or environmental characteristics increasing the likelihood of delays in child development. Meanwhile, protective factors are conditions that can minimize risks and favor the acquisition of skills. Infants with risk indicators for hearing loss (RIHL) tend to live in less stimulating environments which may lead to lower cognitive, language, and motor development.

OBJECTIVE

To compare the cognitive, language, and motor development of infants under the influence of risk and protective factors.

METHOD

A cross-sectional observational study in which 259 infants aged 8-10 months were assessed for cognitive, language, and motor development using the Bayley Scales of Infant and Toddler Development - Third Edition (BSITD-III). The groups were formed according to the presence or absence of RIHL and the quality of the resources, being: SG-AE (Study Group with Adequate Environment), SG-IE (Study Group with Inadequate Environment), CG-AE (Compared Group with Adequate Environment)) and CG-IE (Compared Group with Inadequate Environment). Affordances were assessed using the questionnaire Affordances in the Home Environment for the Motor Development - Infant Scale (AHEMD-IS). The groups were compared using the Chi-square test or the Kruskal-Wallis test, followed by Dunn's multiple comparison test. The level of significance adopted was 5%.

RESULTS

Infants from the CG-AE performed better than the other groups in cognition and motor skills. The CG-AE language was statistically superior to the SG-IE. SG-IE showed the highest frequency of delays in all domains. CG-IE and SG-AE showed a similar frequency of delays. Adequate environment associated with the absence of RIHL (CG-AE) leads to better cognitive, language, and motor performances.

CONCLUSION

Biological and environmental risk factors have a similar impact on development, but the accumulation of both tends to increase the risks of developmental delay. The absence of RIHL and quality environments worked as protective factors and favored the acquisition of skills.

Sistematização de instrumentos de avaliação para os dois primeiros anos de vida de bebês típicos ou em risco conforme o modelo da CIF

RESUMO O objetivo deste trabalho foi identificar instrumentos de avaliação do desenvolvimento neuropsicomotor (DNPM) de crianças de 0 a 2 anos, de baixo custo, que possam ser usados no contexto de creche e/ou ambiente clínico em programas de intervenção precoce, sistematizando esses instrumentos conforme o modelo biopsicossocial da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF). Foram selecionados instrumentos de avaliação do DNPM com tradução ou adaptação para o Brasil. Para isso os domínios da CIF foram escolhidos triangulando o checklist da própria CIF-CJ, core set de estimulação precoce e a última versão da CIF, para busca na literatura de instrumentos de avaliação. A sistematização das categorias selecionadas da CIF foi realizada por dois fisioterapeutas, e um terceiro para itens discordantes. As escalas que responderam aos critérios foram: Alberta Infant Motor Scale (AIMS), Teste de Triagem de Denver II, Inventário Pediátrico sobre Qualidade de Vida (PedSQl®), Affordance in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) e vínculo mãe-bebê. Mesmo com essas escalas, verificou-se a necessidade de um questionário de anamnese complementar para o responsável, dados da Caderneta de Saúde da Criança e de um questionário socioeconômico da Associação Brasileira de Empresas de Pesquisa para o Brasil (ABEP). Essa sistematização está disponível no apêndice, e procura facilitar o olhar ampliado do fisioterapeuta ou profissional da educação com abrangência biopsicossocial dos bebês, além de possibilitar a identificação de riscos de forma precoce e subsidiar ações de promoção e intervenção em diferentes contextos.

Home environment of infants with risk indicators for hearing loss tends to be less stimulating

OBJECTIVE

To verify the home opportunities to the motor development offered to infants with and without risk indicators for hearing loss (RIHL).

METHODS

Observational transversal study was done with infants between 8 and 10 months, being 77 with RIHL (Study Group-SG) and 77 without RIHL (Control Group-CG) The instrument used to characterize the sample and obtain information about the home affordances was the questionnaire Affordances in the Home Environment for the Motor Development - Infant Scale (AHEMD-IS). The results of the AHEMD-IS between the groups were compared using the Mann-Whitney and Chi-Squared tests. The significance test adopted for the study was 5%.

RESULTS

Absolute values in the frequency of homes considered "moderately adequate" and "less than adequate" were greater in the SG in the most part of the categories, except the item Toys for Fine Motricity. It was possible to observe a statistically significant difference in the Total Score of the groups (p-value = 0.01346). Even with better results when compared with the SG, the number of homes of the CG group with affordances below expected is more than half of the sample.

CONCLUSIONS

It was possible to verify that home of infants with risk indicators for hearing loss have statistically less affordances when compared to the homes of infants without the indicators. The results alert us to the need of orientation to the infant's responsible/caretakers regarding to the importance of a favorable environment with stimulation of the infant motor development.

The Impact of Home Motor Affordances on Motor, Cognitive and Social Development of Young Children

OBJECTIVE

The present study evaluated the influence of home motor affordances on motor, cognitive, and social development of young children.

MATERIALS & METHODS

The sample consisted of 49 Iranian children, aged 24-42 months. This study was conducted in Qouchan, Khorasan, Iran in 2015. They was randomly selected by multi-stage cluster sampling from a single community. Participant's homes were assessed using the Affordances in the Home Environment for Motor Development (AHEMD). The motor behavior of young child was measured with the Denver Developmental Screening Test, aspects of cognitive development (Total cognitive, Verbal IQ, and non-verbal IQ) were assessed using the Stanford-Binet scale, and finally, social development measured by the Vineland Adaptive Behavior Scale.

RESULTS

Although no statistically significant correlations were found between Total AHEMD scores and motor development, there were significant and positive correlations (P=0.04) for Total AHEMD with total cognitive development (r=0.29), verbal IQ (r=0.29), social development (r=0.33) and (P=0.019), SES (r=0.51) with (P=0.000). There was a significant relationship between the Play Materials subscale of the AHEMD with total cognitive development (r=0.32) with (P=0.024), verbal IQ (r=0.31) and (P=0.029), and social development (r=0.35) with (P=0.012). In addition, there were significant differences between total AHEMD score with parents who had an academic education.

CONCLUSION

Motor affordances in the home can have a significant positive influence on a young child's cognitive and social development.

Family-Centered Early Intervention Program for Brazilian Infants with Congenital Zika Virus Syndrome: A Pilot Study

Aims: To evaluate the effects of a 16-week program based on Goals-Activity-Motor Enrichment (GAME) principles on infants with congenital Zika virus syndrome (CZS)'s mother report of functional goal achievement, motor and cognitive abilities, home enrichment, and parents' perceptions regarding the service provided. Methods: Quasi-experimental study with infants (n = 32) with CZS and their mothers. Twenty-two infants composed the GAME-based group and 10 were included in the control group. The primary outcome measure was the Canadian Occupational Performance Measure. Secondary outcome measures were the Bayley Scales of Infant and Toddler Development, the Affordances in the Home Environment for Motor Development-Infant Scale, and the Measure of Processes of Care. All measures were performed by blinded assessors. Results: Mothers of infants in the GAME-based group reported significant improvements in their infants' performance on functional priorities (p = 0.0001) and satisfaction with their infants' performance (p = 0.0001), the extent in which services promoted enabling and partnership (p = 0.021), provided general information (p = 0.039), specific information (p = 0.0001), and an enriched home environment (p = 0.0001). Infants in both groups did not improve in motor or cognitive abilities. Conclusions: A family-centered early intervention program based on GAME principles improved mothers' individualized outcomes and enriched infants with CZS's environment. Future studies should elucidate long-term benefits of interventions for this population.

Motor development in school-age children is associated with the home environment including socioeconomic status

The aim of the present study was to examine how the home environment, including socioeconomic status (SES), affects motor development in school-age children. Seven hundred seven children (332 boys and 375 girls) aged between 6 and 10 years participated in the study. Motor Development was determined using the Bruininks-Oseretsky Test of Motor Proficiency-Second Edition. Parents answered the Middle Childhood Home Observation Measurement of the Environment (HOME) Inventory, and Brazilian Association of Market Research Institutes Questionnaire (for SES). Children from "Adequate" homes (HOME score), compared with "Less Adequate," displayed better motor behavior. Mediation and moderation analysis revealed that motor development increased as SES increased. The proportion of variance in motor development explained by SES increased from 9% to 13% when the home was added as a mediation variable. We also found that the effect of SES on motor development was moderated by age. For older children, the effect was lower than for younger children. The best model used SES as the predictor, HOME as the mediator, and AGE as the moderator variable and explained 17% of the variance in motor development. In summary, these findings suggest that, like previous reports with young children, the HOME environment and SES may play an important role in motor development of school-age children. Our findings encourage the assessment of the home and interventions that take into account the home environment to improve motor development in school-age children.

Influência do ambiente domiciliar no desenvolvimento motor de lactentes com síndrome de Down

RESUMO Crianças com síndrome de Down apresentam atrasos no desenvolvimento neuropsicomotor relacionados a tônus muscular, controle postural e equilíbrio. O desenvolvimento motor sofre interferência multifatorial, que envolve características biológicas, psicológicas, sociais e ambientais. Assim, o ambiente em que o lactente está incluído pode atuar como facilitador do desenvolvimento neuropsicomotor. O objetivo deste estudo foi avaliar a influência do ambiente domiciliar no desenvolvimento motor de lactentes com síndrome de Down. Participaram do estudo 16 lactentes com a síndrome, divididos em grupo I (3 a 11 meses) e grupo II (12 a 18 meses), avaliados pela Alberta Infant Motor Scale (AIMS) e pelo questionário Affordances in the Home Environment for Motor Development - Infant Scale (AHEMD-IS). A análise de dados foi feita por meio do teste de Kruskal-Wallis, coeficiente de correlação de Spearman e teste de razão de verossimilhança. Os resultados evidenciaram uma correlação positiva significativa entre o escore bruto da AIMS e a variedade de estímulos (p=0,01, r=0,78) e com o escore total do questionário AHEMD-IS (p=0,02, r=0,74) no grupo II. Verificou-se, ainda, correlação entre a renda familiar e as oportunidades com brinquedos de função motora grossa (p=0,05, r=0,49), porém com correlação fraca. Conclui-se que o ambiente domiciliar tem importante papel no desenvolvimento motor de crianças com síndrome de Down entre 12 e 18 meses, por proporcionar oportunidades de vivências e experimentações. Assim, pode-se afirmar que ambientes mais adequados proporcionam melhor desempenho motor.

Cognição e ambiente são preditores do desenvolvimento motor de bebês ao longo do tempo

RESUMO Investigou-se longitudinalmente relações entre desenvolvimento motor e cognitivo, aspectos biológicos, práticas maternas, conhecimento parental e ambiente familiar de bebês. Participaram do estudo 49 bebês (3-16 meses) avaliados com a Alberta Infant Motor Scale e a Escala Mental da Bayley Scale of Infant Development. Os pais responderam o questionário sobre fatores biológicos, Daily Activities of Infant Scale, o Affordances no Ambiente Domiciliar para o Desenvolvimento Motor - Escala Bebê, e o Inventário sobre Conhecimento do Desenvolvimento Infantil. Avaliações foram conduzidas nas escolas ao longo de 4 meses. Foram utilizadas Equações de Estimativa Generalizada, teste de Bonferroni e coeficiente de correlação de Spearman. Observaram-se associações significativas na (1) análise univariada entre desenvolvimento motor e cognitivo e fatores ambientais (escolaridade, renda, disponibilidade de brinquedos, espaço físico, práticas e conhecimento parental, tempo de aleitamento e frequência na escola); (2) multivariada entre o desenvolvimento motor e renda, idade do pai e espaço físico da residência. Concluiu-se que os desenvolvimentos motores e cognitivos se mostraram interdependentes e fatores ambientais se mostraram mais significativos nas associações em detrimento dos biológicos, reforçando-se a importância do lar, do cuidado dos pais e das experiências que a criança vivencia ao longo dos primeiros anos de vida.
