Cross-sectional association of light sensor-measured time outdoors with physical activity and gross motor competency among U.S. preschool-aged children: the 2012 NHANES National Youth Fitness Survey.

BACKGROUND: Time spent outdoors (outdoor time) has been suggested to be beneficial for physical activity (PA) and healthy development among preschool-aged children. The aim of this study was to quantify PA level and gross motor competency associated with light sensor-measured daily outdoor time in a representative sample of U.S. children aged 3 to 5 years. METHODS: The study sample included 301 participants (149 girls) aged 3 to 5 years from the 2012 U.S. National Health and Examination Survey National Youth Fitness Survey. ActiGraph GT3X+ accelerometers with a built-in ambient light sensor were used to measure PA (expressed in monitor-independent movement summary [MIMS]) and outdoor time. The Test of Gross Motor Development-Second Edition (TGMD-2) was used to assess gross motor skills. Multivariable linear regression models were fit to predict daily and gross motor scores by daily outdoor time. RESULTS: Average daily outdoor time was 95 min (median of 84 min; interquartile range of 52 to 123 min). Means of daily outdoor time and daily MIMS were not significantly different between boys and girls. Among girls, every additional 10 min of daily outdoor time was associated with an additional 540 daily total MIMS (95% CI = 372, 708). Among boys, every additional 10 min of daily outdoor time was associated with an additional 296 daily total MIMS (95% CI = 131, 460). Every additional 10 min of daily outdoor time was associated with a 0.1-point (95% CI = 0.001, 0.130) higher object control standard score. Daily outdoor time was not associated with a locomotor standard score. CONCLUSIONS: In a representative sample of U.S. preschool-aged children, daily outdoor time was positively associated with daily PA. The contribution of outdoor time to PA was greater among girls than boys, suggesting that providing outdoor opportunities is critical for promoting PA, particularly among girls.

The Associations of Child's Clinical Conditions and Behavioral Problems with Parenting Stress among Families of Preschool-Aged Children: 2018-2019 National Survey of Child Health.

To understand parental stress resulting from parenting young children, the current literature has primarily focused on families of children with clinical conditions, but has placed far less attention on the general population. The aim of this study was to examine parenting stress related to children's clinical conditions and behavioral problems in a nationally representative sample of US children aged 3 to 5 years. The study sample included 8454 children aged 3 to 5 years and their parents who participated in the 2018-2019 US National Survey of Child Health (NSCH). Using online/paper NSCH questionnaires, parents reported their children's special health care needs (SHCN), clinically diagnosed mental, emotional, developmental, and behavioral (MEDB) problems (e.g., anxiety problem, developmental delay), and externalizing behaviors. Parents also reported the frequency of feeling aggravated from parenting the participating child as an indicator of elevated parenting stress. In the sample, the prevalence of elevated parenting stress was 5.1% overall (95% CI = 4.2, 6.0); however, it was significantly higher among parents of children with SHCN (20.8%; 95% CI = 16.7, 24.9), with MEDB problems (24.8%; 95% CI = 19.9, 29.8), and with externalizing behavior problems (14.7%; 95% CI = 11.8, 17.6). A multivariable logistic regression model showed that elevated parenting stress was associated with the child's SHCN (adjusted odds ratio [AOR] = 2.3; 1.3, 3.9), MEDB problems (AOR = 4.8; 95% CI = 2.5, 9.1), and externalizing behavior problems (AOR = 5.4; 95% CI = 3.1, 9.4). Even in children without SHCN or MEDB problems, externalizing behavior problems were associated with elevated parenting stress (AOR = 6.4; 95% CI = 3.3, 12.7). The findings call for greater attention to subclinical or yet to be diagnosed externalizing behavior problems among the general preschool-aged child population and their underestimated impact on parenting stress.

Evaluation of Pediatrician Adherence to the American Academy of Pediatrics Health Supervision Guidelines for Down Syndrome.

The American Academy of Pediatrics's guideline on health supervision for children with Down syndrome (DS) offers pediatricians guidance to improve detection of comorbid conditions. Pediatrician adherence has not yet been comprehensively evaluated. Medical records of 31 children with DS who received primary care at two urban academic clinic sites from 2008-2012 were reviewed. Data was extracted on adherence to age-specific individual guideline components for each subject by year-of-life (total 84 years-of-life). Overall adherence across all components was 83% (2001 guideline) and 67% (2011 guideline). Adherence to thyroid, hearing, vision, and developmental components was >85%, and anticipatory guidance regarding atlantoaxial instability and sexuality was <35%. Overall adherence was higher when a subject was younger and when a provider was an attending-level pediatrician.
