Screen time and allostatic load among youth
BACKGROUND: More screen time (ST) is associated with dysregulation of the individual biological systems (cardiovascular, immune, metabolic, and neuroendocrine) involved in the stress response in youth. However, its relationship with allostatic load (AL), a measure of the cumulative physiological stress response, is unclear in youth. PURPOSE: To investigate the associations between ST types and AL outcomes in youth and to explore sociodemographic …
Physical Activity and Sedentary Time Among Mothers of School-Aged Children
The Acute Relationship between Affective States and Stress Biomarkers in Ethnic Minority Youths
Background : Whether affective states acutely predict the hypothalamic-pituitary-adrenal (HPA) axis activities and whether energy balance-related behaviors moderate the affect-HPA axis relationship in obese youths are not well-understood. Methods : 87 mostly obese (94.3% obese) minority adolescents (mean: 16.3 ± 1.2 years old; 56.8% Latino and 43.2% African American) participated in a randomized crossover trial in an observation laboratory, where…
Cross-Sectional and Longitudinal Associations between Non-School Time Physical Activity, Sedentary Time, and Adiposity among Boys and Girls
This study investigated the cross-sectional and longitudinal associations of the substitution of non-school time light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), and sedentary time (ST) with adiposity in boys and girls. Boys ( n = 65, baseline M age= 9.93 ± 0.86 years) and girls ( n = 77, baseline M age = 10.17 ± 0.95 years) wore waist-worn accelerometers (ActiGraph GT3X) at baseline and at a 30-month follow-up, from …
Physical Activity, Step Counts, and Grip Strength in the Chinese Children and Families Cohort Study
Device and question-based measurement of PA and strength were readily accepted in these Chinese urban and rural populations. The PAQ on physical activity in the past year produced some plausible population averages, but individual responses suggested recall challenges. If data about specific activities are required, future studies should explore use of standardized survey questions concerning such fewer specific activities or instruments examinin…
Doing exercise or sport together with one’s child is positively associated with mothers’ momentary affect in daily life, but not with higher levels of overall physical activity
Due to the positive effect on momentary affect, combining spending time together with one's child and simultaneously doing exercise/sport might be a good strategy of pairing two relevant personal goals. However, this strategy was not associated with sufficient MVPA
Dual Versus Single Parental Households and Differences in Maternal Mental Health and Child’s Overweight/Obesity
A US/Mexico Study of Joint Associations of Physical Activity and Sedentary Behavior on Anthropometric Indicators, Migration Status, Country of Birth and Country of Residence
Joint categories of PA and SB were associated with BMI and WC by migration status, nativity and country of residence among populations with Mexican ethnicity
