BACKGROUND: During the past 3 decades, numerous cities and states have adopted laws that ban smoking in public indoor spaces. The rationale for these policies has been to protect nonsmokers from the adverse health effects of secondhand smoke.

OBJECTIVE: To determine whether the implementation of indoor smoking legislation is associated with a decrease in emergency department visits for asthma in children.

METHODS: This retrospective analysis used a natural experiment to estimate the impact of clean indoor air legislation on the rate of emergency department admissions for asthma exacerbation in children. Data were obtained from the Pediatric Health Information System. A …

High-level exposures to a number of agents are known to have direct nephrotoxic effects in children. A growing body of literature supports the hypothesis that chronic, relatively low-level exposure to various nephrotoxicants may also increase the risk for chronic kidney disease (CKD) or accelerate its progression. In this review we highlight several environmental nephrotoxicants and their association with CKD in children and adolescents. We also discuss unique epidemiological challenges in the use of kidney biomarkers in environmental nephrotoxicology.

OBJECTIVES: To compare adolescents' physical activity at home, near home, at school, near school, and at other locations.

METHODS: Adolescents (N = 549) were ages 12 to 16 years (49.9% girls, 31.3% nonwhite or Hispanic) from 447 census block groups in 2 US regions. Accelerometers and Global Positioning System devices assessed minutes of and proportion of time spent in moderate to vigorous physical activity (MVPA) in each of the 5 locations. Mixed-effects regression compared MVPA across locations and demographic factors.

RESULTS: Forty-two percent of adolescents' overall MVPA occurred at school, 18.7% at home, 18.3% in other (nonhome, nonschool) locations, and …
