Low prevalence of physical activity (PA) and high levels of sedentary behavior (SB) are independent public health concerns ( Greer, Sui, Maslow, Greer, & Blair, 2015 ; Maher, Mire, Harrington, Staiano, & Katzmarzyk, 2013 ). In response to this problem, considerable research efforts have focused on

Regular physical activity among children and youth (ie, adolescents) has been consistently associated with decreased adiposity, healthy cardiometabolic biomarkers, improved physical fitness, and better bone health, as well as with favorable psychological and cognitive health outcomes. 1 The public

The overall health benefits of physical activity (PA) are well documented. 1 Among youth, PA is known to have positive effects on cardiovascular, bone, and metabolic health; improving fitness; weight status; sleep; and mental health. 1 , 2 The current guidelines for children between 5 and 18

A widely used tool to assess physical activity (PA) and sedentary behavior (SB) is the wearable accelerometer. Accelerometers are often used in free-living settings for surveillance and intervention studies. To quantify the amount and intensity of body movement, prediction models are applied to

Individuals who engage in regular physical activity have a lower risk of chronic disease and premature death. 4 Walking, in particular, has been

Physical activity recall instruments provide an inexpensive method of collecting physical activity patterns on a sample of individuals, but they are subject to systematic and random measurement error. Statistical models can be used to estimate measurement error in activity recalls and provide more accurate estimates of usual activity parameters for a population.
We develop a measurement error model for a short-term activity recall that describes the relationship between the recall and an individual’s usual activity over a long period of time. The model includes terms for systematic and random measurement errors. To estimate model parameters, the design should include replicate observations of a concurrent activity recall and an objective monitor measurement on a subsample of respondents.
We illustrate the approach with preliminary data from the Iowa Physical Activity Measurement Study. In this dataset, recalls tend to overestimate actual activity, and measurement errors greatly increase the variance of recalls relative to the person-to-person variation in usual activity. Statistical adjustments are used to remove bias and extraneous variation in estimating the usual activity distribution.
Modeling measurement error in recall data can be used to provide more accurate estimates of long-term activity behavior.

Inclusion is a process that encourages individuals with a wide range of abilities to engage together in meaningful participation in an environment that fosters a sense of belongingness and autonomy ( DePauw & Doll-Tepper, 2000 ; Goodwin, 2003 ; Grenier, 2011 ). Inclusive physical activity (PA

The 2008 Physical Activity Guidelines recommend youth participate in a variety of physical activities; however, few nationally representative studies describe the types and variety of youth activity. This study assessed the most frequently reported types and variety of activities among U.S. high school students, and examined the association between variety and meeting the 2008 Guidelines for aerobic activity (aerobic guideline).
We analyzed data on 8628 U.S. high school students in grades 9–12 from the 2010 National Youth Physical Activity and Nutrition Survey. Types of physical activity were assessed by identifying which activities each student reported in the past 7 days. Variety was assessed by the total number of different activities each student reported. Percentage (95% CI) of students who reported engaging in each activity was assessed. Logistic regression was used to examine the association between variety and meeting the aerobic guideline.
Walking was the most frequently reported activity among U.S. high school students. On average, students reported participating in 6 different activities. Variety was positively associated with meeting the aerobic guideline.
These findings support encouraging youth to participate in many physical activities and may be useful for developing interventions that focus on the most prevalent activities.

Most youth are not meeting physical activity guidelines, and schools are a key venue for providing physical activity. School districts can provide physical activity opportunities through the adoption, implementation, monitoring, and evaluation of policies. This paper reports results of a 2009 survey of California school governance leaders on the barriers and opportunities to providing school-based physical activity and strategies to promote adoption of evidence-based policies.
California school board members (n = 339) completed an 83 item online survey about policy options, perceptions, and barriers to improving physical activity in schools.
Board members’ highest rated barriers to providing physical activity were budget concerns, limited time in a school day, and competing priorities. The key policy opportunities to increase physical activity were improving the quantity and quality of physical education, integrating physical activity throughout the school day, supporting active transportation to/from school, providing access to physical activity facilities during nonschool hours, and integrating physical activity into before/after school programs.
Survey findings were used to develop policy resources and trainings for school governance leaders that provide a comprehensive approach to improving physical activity in schools.
