To determine the prevalence and determinants of physical activity in older Koreans, we assessed KNHANES-V, a cross-sectional and nationally representative survey conducted by the Korean Ministry of Health and Welfare. We also compared population estimates based on age, gender and major chronic conditions that the elderly frequently reported. In the data from KNHANES-V, 1964 out of 6193 were age...

Anthrax toxin comprises three different proteins, jointly acting to exert toxic activity: a non-toxic protective agent (PA), toxic edema factor (EF), and lethal factor (LF). Binding of PA to anthrax receptors promotes oligomerization of PA, binding of EF and LF, and then endocytosis of the complex. Homomeric forms of PA, complexes of PA bound to LF and to the endogenous receptor capillary morph...

In this review, we identify the health benefits associated with physical activity (PA); address the physical activity and sedentary guidelines issued by public health scientists as well as children's compliance to these guidelines; discuss the importance of motor skill acquisition during early childhood; and identify different settings that contribute to physical activity participation and stra...

The prevalence of overweight and obese in the U.S. has been thoroughly documented. With the advent of inactivity physiology research and the subsequent interest in sedentary behavior, the work environment has come under closer scrutiny as a potential opportunity to reverse inactivity. Therefore, the purpose of this study was to determine the sitting and physical activity (PA) habits among diffe...

Children’s motivation towards Physical Education (PE) decreases over the elementary school year, but little is known about how and why those declines influence changes of children’s intention and Physical Activity (PA). Guided by the expectancy-value model, this study attempted to examine the relationship between changes of children’s motivation to changes in children’s intention for future par...

OBJECTIVES Traditional physical activity (PA) programs have not been effective in increasing PA in African American girls. Currently, there is limited information regarding the components of PA programs that drive participation in African American girls. The purpose of our investigation was to describe the facilitators, barriers, and components of a culturally tailored afterschool PA program th...

Organized and unorganized physical activity (PA) hold an important role in the daily life of children and adolescents. Regular representative tracking of PA in different settings is important to evaluate social trends and implemented interventions. In this paper, representative PA data of German children and adolescents from the MoMo Baseline-Study (2004, n = 4528) are compared to those of Wave...

OBJECTIVE To assess the relation of physical activity (PA) with feelings of sadness and suicidal thoughts and behaviors among Hispanic and non-Hispanic white adolescent boys and girls. DESIGN Cross-sectional study using a modified 2001 Youth Risk Behavior Survey. PARTICIPANTS One thousand eight hundred seventy Hispanic and non-Hispanic white adolescents, aged 14 to 18 years, attending high ...

BACKGROUND Evidence suggests that differences exist in physical activity (PA) participation among Culturally and Linguistically Diverse (CALD) children and adolescents. It is possible that these differences could be influenced by variations in measurement technique and instrument reliability. However, culturally sensitive instruments for examining PA behaviour among CALD populations are lacking...
