Background: Availability of parks is associated with higher levels of physical activity among children and adolescents. Few studies examine actual park use and park-based physical activity in these populations.
Purpose: This study examined associations among individual, park, and neighborhood environmental characteristics and children's and adolescent's park-based physical activity.
Methods: Data were collected in 2007 on 2712 children in 20 randomly selected parks in Durham NC. The System for Observing Play and Recreation in Communities (SOPARC) provided measures of physical activity. Hierarchic regression analysis assessed associations among individual, park, and neighborhood environmental characteristics and children's park-based physical activity. Data were analyzed in 2010.
Results: Of the 2712 children observed, 34.2% and 13.2% were engaged in walking or vigorous physical activity. Environmental features of parks were associated with activity levels whereas neighborhood characteristics were not. Physical activity was negatively associated with gender (girls) (p=0.003); presence of a parent (p<0.0001); presence of nonparental adult (p=0.006); and an interaction involving the 0-5 years age group and style of play (p=0.017). Higher level of physical activity was associated with presence of other active children (p<0.0001); courts (e.g., basketball); and an interaction between number of recreation facilities and formal activities (p=0.004).
Conclusions: These social factors and design features should be considered in order to stimulate higher levels of park-based physical activity among children and adolescents.

IntroductionAsthma attacks are set off by triggers such as pollutants from the environment, respiratory viruses, physical activity and allergens. The aim of this research is to create a machine learning model using data from mobile health technology to predict and appropriately warn a patient to avoid such triggers.MethodsLightweight machine learning models, XGBoost, Random Forest, and LightGBM were trained and tested on cleaned asthma data with a 70-30 train-test split.

The dorsolateral prefrontal cortex (dlPFC) is increasingly targeted by various noninvasive transcranial magnetic stimulation or transcranial current stimulation protocols in a range of neuropsychiatric and other brain disorders. The rationale for this therapeutic modulation remains elusive. A model is proposed, and up-to-date evidence is discussed, suggesting that the dlPFC is a high-level cortical centre where uncertainty management, movement facilitation, and cardiovascular control processes are intertwined and integrated to deliver optimal behavioural responses in particular environmental or emotional contexts.

Sedentary lifestyles and prolonged physical inactivity are often linked to poor mental and physical health as well as an increased risk of a number of chronic illnesses, including cancer, obesity, type 2 diabetes, and cardiovascular problems. Metabolic Syndrome (MetS), as the new disease, has emerged as the world's leading cause of illness. Despite having its roots in the West, this issue has now completely globalized due to the development of the Western way of life throughout the world.

Background: Increased burden of socially determined vulnerabilities (SDV), which include nonmedical conditions that contribute to patient health, is associated with incident heart failure (HF). Mediators of this association have not been examined. We aimed to determine if a healthy lifestyle mediates the association between SDV and HF.

Modulating immune function is a critical strategy in cancer and atherosclerosis treatments. For cancer, boosting or maintaining the immune system is crucial to prevent tumor growth. However, in vascular disease, mitigating immune responses can decrease inflammation and slow atherosclerosis progression.
