RESUMO

OBJECTIVE: To characterize the environmental factors of children and adolescents with Cerebral Palsy (CP) in the state of Minas Gerais (MG), Brazil. METHODS: This is a cross-sectional study involving 164 caregivers of children/adolescents with CP, aged 1-14 years. The Gross Motor Function Classification System (GMFCS) and the Manual Ability Classification System (MACS) were used to classify the participants' functioning, and environmental factors were evaluated by an on-line questionnaire that examined products and technologies, physical environment, services, and systems. A descriptive analysis was performed using percentage and frequency. RESULTS: Most participants had bilateral CP (66.9%) and 45% of them were spastic. Levels II and V of the GMFCS and MACS were the most frequent. About half (49.4%) used anticonvulsants, 27.4% underwent botulinum toxin application, and 29% went through orthopedic surgery in the lower limbs. Among the participants, 71.3% used orthoses in the lower limbs, and 51.8% used the public health care system. Most had access to physiotherapy (91.5%), but found difficulties to access interventions with other professionals, such as psychologists (28%) and nutritionists (37.8%). The school was the most frequently adapted environment (78%), and had the highest level of structural adaptation (42.7%). CONCLUSIONS: The results of this study suggest that the barriers to access health services and barriers to the physical environment may impact participation and social inclusion.

RESUMO Objetivo: Caracterizar os fatores ambientais de crianças e adolescentes com paralisia cerebral (PC) no estado de Minas Gerais (MG), Brasil. Métodos: Trata-se de um estudo transversal envolvendo 164 cuidadores de crianças/adolescentes com PC, na faixa etária de um a 14 anos. O Sistema de Classificação da Função Motora Grossa (GMFCS) e o Sistema de Classificação da Habilidade Manual (MACS) foram utilizados para classificar a funcionalidade dos participantes e os fatores ambientais foram avaliados por um questionário on-line que abordou produtos e tecnologias, ambiente físico, serviços e sistemas. Análises descritivas foram realizadas por meio de porcentagem e frequência. Resultados: A maioria dos participantes tinha PC bilateral (66,9%) e 45% deles eram espásticos. Os níveis II e V do GMFCS e MACS foram os mais frequentes. Cerca de metade (49,4%) fazia uso de anticonvulsivantes, 27,4% realizaram aplicação de toxina botulínica e 29% cirurgia ortopédica em membros inferiores. Utilizavam órteses em membros inferiores 71,3% e eram usuários do sistema público de saúde 51,8%. A maioria tinha acesso à fisioterapia (91,5%), mas dificuldade de acesso a intervenções com outros profissionais, como psicólogos (28%) e nutricionistas (37,8%). A escola foi o ambiente mais frequentado (78%) e também mais adaptado estruturalmente (42,7%). Conclusões: Os resultados deste estudo sugerem que barreiras de acesso aos serviços de saúde e barreiras no ambiente físico podem impactar a participação e inclusão social.

RESUMO

BACKGROUND: Although it is well known that obesity is frequently associated with reduced levels of habitual physical activity (HPA), which contributes to determining severe oxidative stress and inflammatory state, this association is however unknown in preschoolers so far. This study aimed to investigate the association between biomarkers of redox status and cytokines with different patterns of HPA according to the adiposity of preschoolers. METHODS: A cross-sectional study was conducted in 50 preschoolers (25 overweight/obese, OW/OB and 25 eutrophic, EU), matched for age, sex, economic level, and maternal education. Total antioxidant capacity (TAC), superoxide dismutase (SOD) and catalase (CAT) activities, substances reactive to thiobarbituric acid (TBARS), soluble tumor necrosis factor receptors (sTNFRs), and leptin levels were evaluated. HPA levels were evaluated by accelerometry (ActiGraph GT9X accelerometer). Correlation, multiple linear regression, and partial least squares regression analysis were used to determine the association between redox status biomarkers and cytokines with different patterns of HPA (HPA level, bouts of moderate to vigorous physical activity [MVPA], and multivariate pattern of HPA) in EU and OW/OB preschoolers. RESULTS: OW/OB preschoolers had lower CAT activity, higher levels of TAC, TBARS, and cytokines, and similar levels of HPA to EU preschoolers. In EU preschoolers, SOD activity exhibited a stronger negative association with moderate intensity ranges of HPA (R2 = 0.18), and negative correlation with sTNFRs (r = -0.40 to -0.46). TBARS had a stronger positive association with ranges of light intensity in the multivariate pattern of HPA (R2 = 0.10). In OW/OB preschoolers, the HPA multivariate associative pattern was predominantly from vigorous intensity ranges. Thus, SOD activity had a positive association with the multivariate pattern of HPA (R2 = 0.38) and MVPA bouts (ß [95% CI] = 0.457 [0.0026. 0.0576]). TAC had a negative association with the multivariate pattern of HPA (R2 = 0.38) and MVPA bouts (ß [95% CI] = -0.718 [-0.0025. -0.0003]). Additionally, leptin levels were lower in OW/OB preschoolers engaged in vigorous physical activity (VPA) (8000-9999 counts/min) for longer periods of time. CONCLUSION: The results of this study indicate that OW/OB preschoolers have higher levels of oxidative stress biomarkers and pro-inflammatory cytokines compared to EU preschoolers. Moreover, VPA may exert antioxidative and anti-inflammatory effects in OW/OB preschoolers.

RESUMO

Access to environmental opportunities can favor children's learning and cognitive development. The objectives is to construct an index that synthesizes environmental learning opportunities for preschoolers considering the home environment and verify whether the index can predict preschoolers' cognitive development. A quantitative, cross-sectional, exploratory study was conducted with 51 preschoolers using a multi-attribute utility theory (MAUT). The criteria used for drawing up the index were supported by the literature and subdivided in Group A "Resources from the house" extracted from HOME Inventory including: (1) to have three or more puzzles; (2) have at least ten children's books; (3) be encouraged to learn the alphabet; (4) take the family out at least every 2 weeks. Group B "Screens" (5) caution with using television; (6) total screen time in day/minutes. Group C "Parental Schooling" (7) maternal and paternal education. Pearson correlation analyses and univariate linear regression were performed to verify the relationship between the established index with cognitive test results. The index correlated with the total score of the mini-mental state exam (MMC) and verbal fluency test (VF) in the category of total word production and word production without errors. Multicriteria index explained 18% of the VF (total word production), 19% of the VF (total production of words without errors) and 17% of the MMC. The present multicriteria index has potential application as it synthesizes the preschooler's environmental learning opportunities and predicts domains of child cognitive development.

RESUMO

Background: Preschool is a crucial period for developing motor skills. Objective: This study evaluated factors associated with motor competence in preschoolers from a Brazilian urban area. Methods: A total of 211 preschoolers (51.2% girls and 48.8% boys) were evaluated. Body mass index was calculated; the Brazilian Economic Research Criterion, the Mini-Mental Scale (MMC) and the Early Childhood Environment Rating Scale®, Revised (ECERS-R™) were applied; the Habitual Physical Activity time was recorded; the Test of Gross Motor Development (TGMD-2) was performed. Univariate analysis was performed using simple linear regression for the independent variables, considering the motor test subscales as dependent variables. Variables with p < 0.20 in the univariate analysis were considered for the multiple linear regression model and were entered into the stepwise method. Results: The independent variables remaining in the Standard Score Locomotor model were BMI, presence of park at school, and MMC (R2 = 0.16). The independent variables remaining in the Standard Object Control score were MMC and gender (R2 = 0.03). The variables associated with the highest scores of Gross Motor Quotient were MMC, body mass index, and presence of a park at school, respectively (R2 = 0.11). Conclusion: Male eutrophic preschoolers who are physically active and attend schools with parks or courtyards in a Brazilian urban area have the highest scores for global cognitive function and motor competence.

RESUMO

ABSTRACT Purpose: to examine the influence of familial environment, parental perception, and socioeconomic conditions on the receptive vocabulary of elementary school children. Methods: an analytical cross-sectional observational study. The students were selected by stratified proportional sampling, using the Receptive Vocabulary Test. Those responsible for the children answered the anamnesis and the inventory of family environmental resources. Initially, a bivariate analysis was performed using the chi-square test, considering p<0.20. In the multivariate analysis of binary logistic regression, p<0.05 was considered, and the quality of the model was evaluated through the Hosmer-Lemeshow method. Results: out of the 263 students, 131 were males, 142 were in the third grade and were on average 7.6 years old (±0.57), and 111 had a low receptive vocabulary. In the bivariate analysis, there was a relationship between parental perception about learning to read and write, school failure, and the outcome (p<0.05). The variables environment, resources, and stability of family life were also used for multivariate analysis (p<0.20). Conclusion: Parental perception of difficulty in reading and writing and a lack of family stability were factors associated with poor receptive vocabulary.

RESUMO Objetivo: verificar a influência do ambiente familiar, percepção parental e condições socioeconômicas no vocabulário receptivo de escolares do ensino fundamental. Métodos: trata-se de estudo observacional transversal analítico. Os escolares, selecionados por amostragem proporcional estratificada, realizaram o Teste de Vocabulário Receptivo. Os responsáveis responderam à anamnese e ao Inventário de Recursos do Ambiente Familiar. Inicialmente, realizou-se análise bivariada pelo teste Qui-quadrado, considerando p<0,20. Na análise multivariada de regressão logística binária, considerou-se o valor p<0,05 e a qualidade do modelo foi avaliada pelo método Hosmer-Lemeshow. Resultados: dos 263 escolares, 131 são do sexo masculino, 142 do terceiro ano, possuem idade média de 7,6 anos (±0,57) e 111 apresentam vocabulário receptivo rebaixado. Na análise bivariada, observou-se relação entre percepção parental acerca do aprendizado da leitura, da escrita, repetência escolar e o desfecho (p<0,05). Também foram para análise multivariada as variáveis recursos do ambiente e estabilidade da vida familiar (p<0,20). Conclusão: a percepção parental de dificuldade de leitura e de escrita e a falta de estabilidade familiar foram fatores associados ao pior vocabulário receptivo.

RESUMO

BACKGROUND: Preschool age (3-5 years old) is a crucial period for children to acquire gross motor skills and develop executive functions (EFs). However, the association between the qualitative gross motor skills and EFs remains unknown in preschoolers, especially among overweight and obese children. METHODS: This was a cross-sectional, exploratory, and quantitative study carried out on 49 preschool children, divided into two subgroups according to their body mass index (overweight/obese: 24; eutrophic [normal weight]: 25). The mean age was 4.59 years. More than half of the sample were boys (55%) and most of the mothers had completed high school (67%) and were class C socioeconomic level (63%). Gross motor skills were assessed using the Test of Gross Motor Development-2, while EFs were evaluated using Semantic verbal fluency (SVF), Tower of Hanoi (TH), Day/Night Stroop, and Delayed Gratification tests. Multiple linear regression models adjusted for sex, age, maternal education, socioeconomic status, quality of the home environment, and quality of the school environment using the stepwise method were executed, considering the cognitive tasks as independent variables and gross motor skills as dependent variable. RESULTS: The overweight/obese preschoolers showed worse locomotor skills than their eutrophic peers and below average gross motor quotient (GMQ). Overweight/obese girls performed worse in OC skills than boys with excess weight. SVF (number of errors) and TH (rule breaks) explained 57.8% of the variance in object control (OC) skills and 40.5% of the variance in GMQ (p < .05) in the overweight/obese children. Surprisingly, there was no significant association between any of the EF tasks and gross motor skills in the eutrophic children. CONCLUSION: A relationship between EF tasks (number of errors in SVF and rule breaks in TH) and gross motor skills (OC and GMQ) was demonstrated in the overweight/obese preschoolers, indicating that worse cognitive flexibility, working memory, planning, and problem solving are associated with worse gross motor skills in this population when compared to eutrophic children.

RESUMO

OBJECTIVE: Determine the social, environmental, and personal factors associated with high fat mass index in preschoolers. DESIGN: A quantitative, exploratory, and cross-sectional study. SETTING AND PARTICIPANTS: Fifty-one Brazilian preschoolers from public schools living in urban areas. MAIN OUTCOME MEASURE(S): The preschoolers' fat mass index was determined using dual-energy radiological absorptiometry. The quality of home and school environments were accessed using the Early Childhood Home Observation for Measurement of the Environment and Early Childhood Environment Rating Scales. The physical activity levels were recorded by accelerometers. The daily energy intake was recorded and sociodemographic data using the Brazilian Economic Classification criterion. Data on exposure time to screens and parental obesity were collected according to the parents' reports. ANALYSIS: Data analyses were performed using simple and multiple regressions models. RESULTS: Parental obesity (ß, 0.516; 95% confidence interval [CI], 2.078-5.133), high quality of environmental stimulation of home (ß, 0.429; 95% CI, 1.294-4.023), and high exposure time to screens (ß, 0.256; 95% CI, 0.215-2.554) explained 43% of preschoolers' high fat mass index. CONCLUSIONS AND IMPLICATIONS: Identification of parental obesity, high quality of environmental stimulation of home, and high exposure time to screens as the most important determinants of the high fat mass index in preschoolers from Brazilian urban areas.

RESUMO

We compared the motor competence between overweight/obese and eutrophic preschoolers with similar physical activity levels, age, socioeconomic status, maternal education, quality of the home environment and quality of the school environment. We also investigated to what extent excess body fat mass explains gross motor skills in preschoolers. A cross-sectional quantitative and exploratory study was conducted with 48 preschoolers assigned into eutrophic and overweight/obese groups. Overweight/obese preschoolers had worse Locomotor subtest standard scores than the eutrophic ones (p = 0.01), but similar Object Control subtest and Gross Motor Quotient scores (p > 0.05). Excess body fat mass explained 12% of the low Locomotor subtest standard scores in preschoolers (R2 = 0.12; p = 0.007). Excess body fat mass was associated with worse locomotor skills when the model was adjusted for physical activity levels, age, socioeconomic status, maternal education, quality of the home environment and quality of the school environment. Thus, excess body fat mass partly explains lower locomotor skills in preschoolers.

RESUMO

BACKGROUND: Active play opportunities seems to influence the level of physical activity during childhood. However, a gap remains about which environmental opportunities including the daycare physical environment could have a positive impact on the level of physical activity in preschoolers. OBJECTIVES: (1) To develop an index to measure the environmental opportunities of free active play for preschoolers of middle-income countries; (2) to check the relationship and contribution of the index to explain objectively the level of physical activity. METHODS: A quantitative, cross-sectional, exploratory study with 51 preschool children. The established criteria for the index according to the literature were: (1) Outdoor time on typical days of the week. (2) Outdoor time on a typical weekend day. (3) The presence of internal space and external environment in the child's home that allows playing. (4) Presence of patio with space for games at the school. (5) Presence of a playground with a toy at the school. We applied multi-attribute utility theory for the determination of the multicriteria index of physical environmental opportunities. Pearson's correlation analysis and simple linear regression were used to verify the association between the index and the physical activity level. RESULTS: The index showed a positive correlation with the level of physical activity, e.g., the average time of MVPA (r = 0.408, p = 0.003). The univariate linear regression demonstrated that the quality of physical environmental opportunities for physical activity explained 20% of the preschooler's classification as active and 16% of the time in moderate to vigorous physical activity (p < 0.001). CONCLUSION: Physical environmental opportunities for active play have a positive effect on physical activity in preschoolers and should be encouraged in different social segments.

RESUMO

Abstract Introduction: Family-Centered Care (FCC) is a philosophy that recognizes the family as a partner in the intervention process and currently constitutes one of the most important practices in pediatric physical therapy intervention. For this reason, FCC should be part of pediatric physiotherapy training so that future physiotherapists are able to include it in their clinical practice. Objective: To verify the feasibility of applying FCC as part of an undergraduate Physiotherapy course, focusing on the activity of children with different health conditions. Methods: This is a case report, based on information collected from medical records, on an intervention program carried out with 5 children and their families, in the home, once a week for seven weeks, by students of physical therapy in pediatrics. For pre- and post-intervention assessment of the children, standardized instruments were used: Gross Motor Function Measure (GMFM) and the Alberta Infant Motor Scale (AIMS). Reports were collected from families and students regarding the FCC experience. Results: The children with neurological impairment increased the GMFM target area score by more than 5%, indicating clinical improvement. A child at biological risk had a pre-intervention AIMS percentile of < 25 and a post-intervention percentile of 50, while another child with developmental delay did not alter his percentile. At the end of the intervention, families reported greater confidence in carrying out activities with their children and students reported the experience as relevant to their professional training. Conclusion: The practical application of FCC proved promising in the academic context of pediatric physical therapy.

Resumo Introdução: O Cuidado Centrado na Família (CCF) é uma filosofia que reconhece a família como parceira no processo de intervenção e, atualmente, constitui uma das práticas mais importantes na intervenção fisioterapêutica pediátrica. Por este motivo, o CCF deveria fazer parte da formação em fisioterapia pediátrica de maneira que futuros fisioterapeutas pudessem inseri-lo em sua prática clínica. Objetivo: Verificar a viabilidade da aplicação do CCF em uma disciplina de graduação em fisioterapia, com foco na atividade de crianças com condições de saúde variadas. Métodos: Trata-se de um relato de casos, a partir de informações coletadas em prontuários, sobre um programa de intervenção realizado com cinco crianças e suas famílias no contexto domiciliar, uma vez por semana, durante sete semanas, por discentes da disciplina de fisioterapia em pediatria. Para a avaliação pré e pós-intervenção das crianças, utilizaram-se instrumentos padronizados: Avaliação da Função Motora Grossa (GMFM) e Escala Motora Infantil de Alberta (AIMS). Foram coletatos relatos das famílias e discentes quanto à experiência com o CCF. Resultados: As crianças com comprometimento neurológico aumentaram a pontuação na área-meta do GMFM em mais de 5%, indicando melhora clínica. Uma criança de risco biológico apresentou AIMS percentil pré de < 25 e pós de 50, enquanto outra criança com atraso no desenvolvimento não alterou seu percentil. Ao final da intervenção, as famílias relataram maior confiança na realização de atividades com suas crianças e os discentes relataram a experiência como relevante na formação profissional. Conclusão: A aplicação prática do CCF mostrou-se promissora no contexto acadêmico da fisioterapia pediátrica.

RESUMO

Resumo Introdução A partir da década de 1990, começou a ocorrer um aumento significativo na produção e uso de motocicletas no Brasil; paralelamente, o número de vítimas fatais de acidentes de transporte terrestre aumentou. Em 2015, os motociclistas foram as principais vítimas fatais. Objetivo Identificar os fatores que motivam os motociclistas a escolher a motocicleta, apesar dos riscos, como um meio de transporte. Este estudo foi fundamentado no conceito de motivação, proposto por Bergamini, e na noção de tempo e espaço, proposta por Harvey. Método Estudo qualitativo, com seleção de amostra por saturação, desenvolvido com os motociclistas vítimas de acidentes de trânsito em um hospital de referência para trauma. O método de coleta de dados foi a entrevista, utilizando um questionário semiestruturado com análise de conteúdo. Resultados Foram entrevistados 15 motociclistas, todos homens, com mediana de idade de 26 anos. Os fatores motivacionais foram: "o tempo", "aspectos financeiros", "gosto pela motocicleta" e "único veículo disponível". Conclusão A motivação maior para o indivíduo escolher a motocicleta como meio de transporte, independentemente de ser ou não motoboy, foi a possibilidade de gerar economia financeira e, ao mesmo tempo, proporcionar um ganho de tempo no dia a dia, embora outros fatores pessoais também tenham contribuído para essa motivação.

Abstract Background Since the 1990s, there has been a significant increase in the production and use of motorcycles in Brazil. At the same time, the number of fatal victims of land transport accidents has increased. In 2015, motorcyclists were the main fatal victims of these accidents. Objective To identify the factors that motivate motorcyclists to choose the motorcycle as a means of transportation despite the risks. This study was based on the concept of motivation proposed by Bergamini and on the notion of time and space proposed by Harvey. Method A qualitative study, with sample selection by saturation, conducted with motorcyclists who were victims of traffic accidents in a reference trauma hospital. The data were collected through semi-structured interviews and analyzed. Results Fifteen motorcyclists, all men with median age of 26 years, were interviewed. The motivational factors revealed were "time", "financial aspects", "motorcycle appreciation", "only vehicle available". Conclusion The greatest motivation for choosing the motorcycle as a means of transportation was the possibility of generating financial savings while providing a daily gain of time, although other factors also contributed to this motivation.

RESUMO

PURPOSE: To identify the factors associated with the cognitive development of children from 24 to 42 months of age, as well as to characterize the availability of toys and resources present in the family environment, and the parental practices that signal family stability. METHODS: Cross-sectional analytical study conducted with children regularly enrolled in public and private educational institutions of a medium-sized city. Cognitive development was assessed by means of the Bayley test and the quality of the environment was evaluated using the Adapted Family Environment Resource Inventory (FERI). The children were allocated into two groups based on the cognitive test result and compared regarding activities performed at home; reports of outings and trips in the last year; presence of regular scheduled activities; activities developed with parents; toys the child has or has had; presence of newspapers, magazines, and books at home; the person responsible for monitoring the child during day-care; and routines of the child and family. RESULTS: Of the 104 children evaluated, 72% were enrolled in the public education network and 69% belonged to economic classes C and D. Regarding cognitive development, 55% had above-average development. In the bivariate analysis, it was observed that greater availability of toys and materials for the child and higher economic levels were related to better scores on the cognitive development test. These remained as predictors of cognitive development in binary logistic regression analysis. CONCLUSION: Greater availability of resources in the family environment and economic levels were positively associated with cognitive development in children.

OBJETIVO: Identificar fatores associados ao desenvolvimento cognitivo de crianças de 24 a 42 meses de idade, assim como caracterizar a disponibilidade de brinquedos e recursos presentes no ambiente familiar e as práticas parentais que sinalizam estabilidade familiar. MÉTODO: Estudo transversal analítico realizado com crianças regularmente matriculadas em instituições de ensino públicas e privadas de uma cidade de médio porte. O desenvolvimento cognitivo foi avaliado por meio do teste Bayley e a qualidade do ambiente que vive a criança foi avaliada utilizando-se o Inventário de Recursos do Ambiente Familiar- RAF adaptado. Para conhecimento do nível econômico das famílias utilizou-se o Critério de Classificação Econômica Brasil 2015 (CCEB). As crianças foram alocados em dois grupos com base no resultado do teste cognitivo e comparadas quanto às atividades e rotinas da família e recursos presentes no domicílio. RESULTADOS: Das 104 crianças avaliadas, 72% são matriculadas na rede de ensino público, 69% pertencentes as classes econômicas C e D. De acordo com o desenvolvimento cognitivo, 55% obtiveram desenvolvimento acima da média aritmética. Na análise bivariada observou-se que os passeios e viagens realizados pela criança, maior escolaridade materna e paterna, vínculo com creches particulares, assim como a maior disponibilidade de recursos e níveis econômicos maiores foram relacionados a melhores escores cognitivos. Os dois últimos fatores permaneceram como preditores do desenvolvimento cognitivo na análise de regressão logística binária. CONCLUSÃO: Maior disponibilidade de recursos no ambiente familiar e níveis econômicos foram positivamente associados ao desenvolvimento cognitivo.

RESUMO

The use of media by children in early childhood is increasingly common, and it is necessary to investigate the determinants of screen time, which is understood as the total child screen exposure time, including television and interactive media. This is a descriptive, exploratory, and cross-sectional study conducted with 180 children between 24 and 42 months of age, allocated in Group 1, less than two hours daily screen exposure time; Group 2, daily screen exposure time equal to or more than two hours. Bivariate and binary logistic regression analyses were performed. Screen time determining factors studied were family environment, evaluated with the Family Environment Resource Inventory; socioeconomic factors; nutritional status and child development status, evaluated with the Bayley III test. As a result, 63% of children had daily screen time exceeding two hours, and television still is the main culprit for children screen exposure. We observed that screen time exposure was positively associated with family resources, economic level, and language development. However, only the last two factors explained the longer screen time.

O uso de mídias por crianças na primeira infância está cada vez mais habitual, o que torna necessário investigar os fatores determinantes para o tempo de tela, entendido como o tempo total pelo qual a criança permanece exposta a todas as telas, incluindo televisão e mídias interativas. Trata-se de um estudo transversal, descritivo e exploratório, realizado com 180 crianças, entre 24 a 42 meses de idade, alocadas em: Grupo 1, exposição à tela inferior a duas horas/dia; Grupo 2, exposição à tela igual/superior a duas horas/dia. Realizou-se análise bivariada e de regressão logística binária. Os fatores determinantes no tempo de tela estudados foram os recursos do ambiente familiar, investigado por meio do Inventário de Recursos do Ambiente Familiar; fatores socioeconômicos; estado nutricional e status do desenvolvimento infantil, mensurado pelo teste Bayley III. Como resultado verificou-se que 63% das crianças apresentaram tempo de tela superior a 2 horas/dia e que a televisão ainda é a principal responsável pela exposição das crianças às telas. Observou-se que o tempo de exposição à tela esteve positivamente associado aos recursos familiares, nível econômico e desenvolvimento da linguagem. Entretanto, apenas os dois últimos fatores explicaram o maior tempo de tela.

Results Of the 104 children evaluated, 72% were enrolled in the public education network and 69% belonged to economic classes C and D. Regarding cognitive development, 55% had above-average development. In the bivariate analysis, it was observed that greater availability of toys and materials for the child and higher economic levels were related to better scores on the cognitive development test. These remained as predictors of cognitive development in binary logistic regression analysis. Conclusion Greater availability of resources in the family environment and economic levels were positively associated with cognitive development in children.

RESUMO

To evaluate whether frequent interactive tablet-use at preschool age is associated with improved fine motor skills and to describe tablet-use in young children. Cross-sectional study with 78 children, aged 24-42 months: group 1 with previous frequent tablet-use exposure (n = 26), group 2 without previous tablet-use exposure (n = 52). Fine motor skills were evaluated with the Bayley-III. Socioeconomic data and home environment quality were similar in both groups. Fine motor skills of group 1 were better than those of group 2 (p = 0.013). Most participating children carried out passive and active tablet activities, usually accompanied by parents, not exceeding time recommendations for young age. We observed a difference in fine motor skills in young children slightly favoring those with tablet-use experience.

RESUMO

OBJECTIVE: To describe the prevalence of interactive media (tablets and smartphones) use by children aged two to four years old, as well as to characterize this use, and investigate habits, practices, parents' participation and opinion about their child's interactive media use. METHODS: A cross-sectional study with 244 parents or legal guardians of children enrolled in daycare centers in a small Brazilian municipality was conducted. A questionnaire based on interactive media use and related habits were applied, and economic level was assessed. Children were divided into three different groups according to media use: Group 1 did not use (n=81); Group 2 uses up to 45 min/day (n=83) and Group 3 uses more than 45 min/day (n=80). Then, they were compared with regard to the sociodemographic variables and media use by the Chi-square test and Student's t-test. RESULTS: The prevalence of interactive media use was 67.2%, with a mean time of use of 69.2 minutes/day (confidence interval of 95% - 95%CI 57.1-81.2). The activities most performed were watching videos (55%), listening to music (33%) and playing games (28%). Most parents reported allowing media use in order to stimulate their child's development (58.4%), accompanying them during use (75.2%), and limiting media time (86.4%). CONCLUSIONS: We observed high interactive media use prevalence. The predominant way of using these devices was marked by parent-child participation. Most parents reported believing in the benefits of interactive media. Passive activities were more frequent, with restricted time of use.

RESUMO

Abstract Aim: to investigate through a systematic review of randomized controlled trials (RCTs) the effects of interactive media on the cognitive, language, and motor development of children and adolescents. Methods: Searches were performed with the Medline, AMED, Embase, PEDro, Cochrane, Psychinfo, and ERIC databases in May 2017 with updated in July 2020. For the search strategy, we used descriptors related to "randomized controlled trial", "interactive media" and "children and adolescents up to 18 years old". RCTs that investigated the effectiveness of interactive media in cognitive, motor, and language development of children and adolescents up to 18 years of age with typical development were included. When appropriate, meta-analyses were conducted using a random-effects model. Pooled data were presented using standardized mean difference and 95% confidence interval. We assessed the quality of evidence using the GRADE methodology and the methodological quality using the PEDro scale. Results: of the trials found, 14 references were eligible for this study. The GRADE methodology was used in 13 RCTs. Estimates showed a low level of evidence of a small effect of media use on cognitive development compared to that in the control group and another intervention. No effect on motor and language development. Conclusion: The results of this systematic review do not support claims about the advantages or disadvantages of interactive media in child development. High-quality evidence was found that interactive media is not superior to other interventions for cognitive and language development outcomes and quality of moderate evidence for motor and language development.

RESUMO Objetivo: Descrever a prevalência do uso de mídias interativas (tablets e smartphones) pelas crianças de dois a quatro anos de idade, assim como caracterizar esse uso, investigar hábitos, práticas, participação e opinião dos pais acerca da sua utilização. Métodos: Estudo transversal com 244 pais ou responsáveis de crianças matriculadas em creches de um município brasileiro de pequeno porte. Foi aplicado um questionário sobre hábitos de utilização de mídias interativas e investigação do nível econômico. As crianças foram divididas em 3 grupos de acordo com o uso das mídias: grupo 1 - não utiliza; grupo 2 - utiliza até 45 minutos por dia; e grupo 3 - utiliza mais do que 45 minutos por dia. Os grupos foram comparados quanto às variáveis sociodemográficas e de caracterização do uso das mídias por meio dos testes do qui-quadrado e t de Student. Resultados: A prevalência do uso de mídias interativas foi de 67,2%, com tempo médio de utilização de 69,2 minutos por dia (intervalo de confiança de 95% - IC95% 57,1-81,2). As atividades mais realizadas foram: ver vídeos (55%), escutar músicas (33%) e jogar games (28%). A maioria dos pais relatou permitir a utilização da mídia para estimular o desenvolvimento do seu filho (58,4%), acompanhá-lo durante o uso (75,2%) e limitar o tempo com a mídia (86,4%). Conclusões: Observou-se elevada prevalência do uso de mídias interativas. A forma predominante de utilização das mídias envolve conjuntamente crianças e pais, os quais acreditam nos seus efeitos benéficos. Atividades passivas são as mais realizadas, com restrição do tempo de uso.
