BACKGROUND: Neutrophil gelatinase-associated lipocalin (NGAL) is a glycoprotein released during early phases of a postischemic kidney in response to kidney injury, inflammation, and oxidative stress. It can be detected in urine after 2 hours of an ischemic event. The aim was to measure and to correlate the level of urine NGAL (uNGAL) with urea, creatinine, and glomerular filtration rate (GFR) of endurance cycling athletes (n = 19) and physically active individuals (control, n = 17)...

BACKGROUND: Residents of more socioeconomically disadvantaged neighborhoods are more likely to report poorer physical function, although the reasons for this remain unknown. It is possible that neighborhood-level perceptions of safety from crime contribute to this relationship through its association with walking for recreation. METHODS: Data were obtained from the fourth wave (collected in 2013) of the HABITAT (How Areas in Brisbane Influence HealTh and AcTivity) multilevel longitudinal study of middle- to older-aged adults (46-74 y) residing in 200 neighborhoods in Brisbane, Australia...

Physical activity can reduce the risk of at least 20 chronic diseases and conditions and provide effective treatment for many of these conditions. Yet, physical activity levels of Americans remain low, with only small improvements over 20 years. The Centers for Disease Control and Prevention (CDC) considered what would accelerate progress and, as a result, developed Active People, Healthy NationSM , an aspirational initiative to improve physical activity in 2.5 million high school youth and 25 million adults, doubling the 10-year improvement targets of Healthy People 2020...

BACKGROUND: Social relationships are among the strongest predictors of health. The extent to which one is embedded in social networks, also referred to as social integration, has been associated with physical activity in short-term longitudinal and cross-sectional studies. How changes in social integration impact physical activity over longer periods of time is not well understood. METHODS: Longitudinal data from 5 waves of the Americans' Changing Lives study were used (wave 1: n = 3617; wave 5: n = 1427)...

BACKGROUND: Extensive research demonstrates the benefits of fitness on children's health and academic performance. Although decreases in health-related fitness may increase school absenteeism, multiple years of prospective, child-level data are needed to examine whether fitness changes predict subsequent chronic absenteeism status. METHODS: Six cohorts of New York City public school students were followed from grades 5-8 (2006/2007-2012/2013; N = 349,381). A longitudinal 3-level logistic generalized linear mixed model with random intercepts was used to test the association of individual children's changes in fitness and 1-year lagged chronic absenteeism...
