Physical activity patterns of ethnic children from low socio-economic environments within the UK

Many children fail to meet physical activity (PA) guidelines for health benefits. PA behaviours are complex and depend on numerous interrelated factors. The study aims to develop current understanding of how children from low Socio-economic environments within the UK use their surrounding built environments for PA by using advanced technology. The environment was assessed in 96 school children (7–9 years) using global positioning system (GPS) monitoring (Garmin Forerunner, 305). In a subsample of 46 children, the environment and PA were assessed using an integrated GPS and heart rate monitor. The percentage of time spent indoor, outdoor, in green and non-green environments along with time spent in moderate-to-vigorous PA (MVPA) in indoor and outdoor environments were assessed. A 2-by-2 repeated measures analysis of covariance, controlling for body mass index, BF%, assessed the environmental differences. The findings show that 42% of children from deprived wards of Coventry fail to meet PA guidelines, of which 43% was accumulated during school. Children engaged in more MVPA outdoor than indoor environments (P < 0.01) and a greater amount of time was spent in non-green environments (P < 0.01). Increased time outdoors was negatively associated with BF%. In conclusion, outdoor environments are important for health-enhancing PA and reducing fatness in deprived and ethnic children.  相似文献   

The Effects of Parental Behavior on Infants' Neural Processing of Emotion Expressions          下载免费PDF全文

Samantha Taylor‐Colls  R. M. Pasco Fearon 《Child development》2015,86(3):877-888

Infants become sensitive to emotion expressions early in the 1st year and such sensitivity is likely crucial for social development and adaptation. Social interactions with primary caregivers may play a key role in the development of this complex ability. This study aimed to investigate how variations in parenting behavior affect infants' neural responses to emotional faces. Event‐related potentials (ERPs) to emotional faces were recorded from 40 healthy 7‐month‐old infants (24 males). Parental behavior was assessed and coded using the Emotional Availability Scales during free‐play interaction. Sensitive parenting was associated with increased amplitudes to positive facial expressions on the face‐sensitive ERP component, the negative central. Findings are discussed in relation to the interactive mechanisms influencing how infants neurally encode positive emotions.  相似文献   

Infant vocalizing and phenotypic outcomes in autism: Evidence from the first 2 years

Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White; collected from 2007 to 2017 near Philadelphia) were analyzed at 6, 12, and 24 months. At 12 months, HR-ASD infants produced fewer vocalizations than HR-Neg infants. From 6 to 24 months, HR-Neg infants demonstrated steeper vocalization growth compared to HR-ASD and LR infants. Finally, among HR infants, vocalizing at 12 months was associated with language, social phenotype, and diagnosis at age 2. Infant vocalizing is an objective behavioral marker that could facilitate earlier detection of ASD.  相似文献   

Responding to racism at school: Ethnic-racial socialization and the academic engagement of Black and Latinx youth     

Kimberly R. Osborne  Ashley A. Walsdorf  Mia A. Smith-Bynum  Samantha Redig  Dawn Brinkley  Margaret Tresch Owen  Margaret O’Brien Caughy 《Child development》2023,94(1):219-236

Guided by the Theory of Racial Socialization in Action (TRSA; Smith-Bynum in press), this study examined observed caregiver-provided ethnic-racial socialization in response to a school-based discriminatory dilemma. Forty-five Black and 36 Latinx caregivers (88% mothers) with low-income and their children (M_age = 11.09, SD = 0.29; 46.3% female) participated in Dallas, Texas from 2018 to 2019. Dyads responded to a hypothetical scenario in which a school counselor makes a discriminatory comment to the child. Results of a factor mixture analysis suggested that caregivers engaged in the dialogue using one of four approaches: Low-engaged, Legacy, Racial Literacy, or High-engaged. Profiles were found to differ significantly by the race/ethnicity and language of caregivers and were associated with youth’s concurrent behavioral engagement (R² = .04).  相似文献   

A mixed-methods evaluation of the experience of emerging young adult care partners     

Allison Marziliano  Allison Applebaum  Samantha Siess  Anne Moyer 《Psychology in the schools》2023,60(1):143-161

There is limited literature on emerging young adult (EYA) care partners, despite a recent rise in interest in this group. The purpose of this study is to compare EYA care partners and their non-care partner peers in the domains of academic achievement and engagement, employment, health-related behaviors and self-care, and mental health and respite, as well as to assess EYA care partners’ burden and potential for positive psychosocial sequelae and life changes as a result of their role. Further, within EYA care partners, we examine the relationship between mental health variables and care partner-relevant variables. Two hundred undergraduates (100 care partners and 100 non-care partners) completed measures of academic achievement and engagement (grade point average and credit load), employment (number of paid positions held and number of hours worked per week), health-related behavior/self-care (visits to the dentist, primary care physician, optometrist, diet healthfulness, exercise, cigarette smoking, and drinks per week) and mental health/respite (depression, anxiety, loneliness, drinking, social support, peer pressure, vacation recency, and frequency). Care partners completed measures of spiritual well-being, burden, meaning, and benefit-finding, as well as provided qualitative feedback on how caregiving changed their lives. EYA care partners and non-care partners did not differ on any variables examined except for the number of jobs held, as EYA care partners held more paid jobs than EYA non-care partners. EYA care partners showed moderate burden and high levels of finding meaning/benefit, the latter of which was supported by the themes that emerged from their qualitative data. Within EYA care partners, we found that depression and anxiety (mental health variables) were significantly related to spiritual well-being, burden, benefit finding, and finding meaning through caregiving (care partner-relevant variables). It is encouraging that the care partner and non-care partner groups were similar in domains critical for this age group, such as academic achievement and engagement.  相似文献
