Physical activity may influence both fat and lean body mass. This study investigated the association between physical activity in children between the ages of 11 and 13 years and both fat and lean mass.
A subsample of the 1993 Pelotas (Brazil) Birth Cohort was visited in 2004–2005 and 2006–2007. Physical activity was estimated through standardized questionnaires. Body composition (ie, fat and lean mass) was measured using deuterium dilution. Those with moderate-to-vigorous activity greater than 420 min/wk were classified as active, and physical activity trajectory was defined as being above or below the cutoff at each visit.
Four hundred eighty-eight adolescents (51.8% boys) were evaluated. The mean difference in fat mass in boys and girls who reported ≥ 420 min/wk of physical activity in both visits compared with those who were consistently inactive was –4.8 kg (P ≤ .001). There was an inverse association between physical activity and fat mass among boys in both crude and confounder-adjusted analyses, whereas for girls, the association was evident only in the crude analysis. There was no significant association between physical activity and lean mass.
Physical activity may contribute to tackling the growing epidemic of adolescent obesity in low- and middle-income countries.

Assessment of physical activity using self-report has the potential for measurement error that can lead to incorrect inferences about physical activity behaviors and bias study results.
To provide recommendations to improve the accuracy of physical activity derived from self report.
We provide an overview of presentations and a compilation of perspectives shared by the authors of this paper and workgroup members.
We identified a conceptual framework for reducing errors using physical activity self-report questionnaires. The framework identifies 6 steps to reduce error: 1) identifying the need to measure physical activity, 2) selecting an instrument, 3) collecting data, 4) analyzing data, 5) developing a summary score, and 6) interpreting data. Underlying the first 4 steps are behavioral parameters of type, intensity, frequency, and duration of physical activities performed, activity domains, and the location where activities are performed. We identified ways to reduce measurement error at each step and made recommendations for practitioners, researchers, and organizational units to reduce error in questionnaire assessment of physical activity.
Self-report measures of physical activity have a prominent role in research and practice settings. Measurement error may be reduced by applying the framework discussed in this paper.

This article describes the procedures and development of the first Portuguese Report Card on Physical Activity in Children and Adolescents.
Comprehensive searches for data related to indicators of physical activity (PA) were completed by a committee of physical activity and sports specialists. Grades were assigned to each indicator consistent with the process and methodology outlined by the Active Healthy Kids Canada Report Card model.
Nine indicators of PA were graded. The following grades were assigned: Overall Physical Activity Levels, D; Organized Sport Participation, B; Active Play, D; Active Transportation, C; Sedentary Behaviors, D; Family and Peers, C; Schools, B; Community and the Built Environment, D; and Government, C.
Portuguese children and adolescents do not reach sufficient physical activity levels and spend larger amounts of time spent in sedentary behaviors compared with recommendations. Effective policies of PA promotion and implementation are needed in different domains of young people’s daily lives.

The validity of physical activity (PA) self-report measures can be a problem when using these measures with target populations that differ from the population for which the measures were originally developed.
Describe an approach to further tailor PA self-report measures to a target community, and report on focus group and cognitive interview findings.
Topics relevant to culturally tailoring measures are discussed, including translation, focus groups, and cognitive interviews. We describe examples from our own work, including focus groups and cognitive interviews conducted to assess Latinos’ interpretations of PA questions derived from various epidemiological surveys that were developed in White communities.
Findings from focus groups and cognitive interviews provide valuable information about the comprehension, interpretation, and cultural relevance of the PA questions to Latino communities.
It is recommended that investigators collect formative data to better assess the equivalence of items being applied to a different cultural group. Guidelines for cultural attunement of self-report instruments are described to promote more uniform and rigorous processes of adaptation and facilitate cross-cultural investigations.

We aimed to determine the likelihood that adult dog owners who walk their dogs will achieve a healthy level of moderate-intensity (MI) physical activity (PA), defined as at least 150 mins/wk.
We conducted a systematic search of 6 databases with data from 1990–2012 on dog owners’ PA, to identify those who achieved MIPA. To compare dog-walkers’ performance with non-dog walkers, we used a random effects model to estimate the unadjusted odds ratio (OR) and corresponding 95% confidence interval (CI).
We retrieved 9 studies that met our inclusion criterion and allowed OR calculations. These yielded data on 6980 dog owners aged 18 to 81 years (41% men). Among them, 4463 (63.9%) walked their dogs. Based on total weekly PA, 2710 (60.7%) dog walkers, and 950 (37.7%) non-dog walkers achieved at least MIPA. The estimated OR was 2.74 (95% CI 2.09–3.60).
Across 9 published studies, almost 2 in 3 dog owners reported walking their dogs, and the walkers are more than 2.5 times more likely to achieve at least MIPA. These findings suggest that dog walking may be a viable strategy for dog owners to help achieve levels of PA that may enhance their health.

The ParticipACTION Report Card on Physical Activity for Children and Youth is the most comprehensive assessment of child and youth physical activity in Canada and provides an update or “state of the nation” that assesses how Canada is doing at promoting and facilitating physical activity opportunities for children and youth. The purpose of this paper is to summarize the results of the 2016 ParticipACTION Report Card.
Twelve physical activity indicators were graded by a committee of experts using a process that was informed by the best available evidence. Sources included national surveys, peer-reviewed literature, and gray literature such as government and nongovernment reports and online content.
Grades were assigned to Daily Behaviors (Overall Physical Activity: D-; Organized Sport and Physical Activity Participation: B; Active Play: D+; Active Transportation: D; Physical Literacy: D+; Sleep: B; Sedentary Behaviors: F), Settings and Sources of Influence (Family and Peers: C+; School: B; Community and Environment: A-), and Strategies and Investments (Government: B-; Nongovernment: A-).
Similar to previous years of the Report Card, Canada generally received good grades for indicators relating to investment, infrastructure, strategies, policies, and programming, and poor grades for behavioral indicators (eg, Overall Physical Activity, Sedentary Behaviors).

Regular physical activity improves physical and mental health, yet children’s physical activity levels were low in England’s 2014 Report Card. Within this paper, we update the 2014 Report Card to assess current information for the 9 indicators of physical activity.
A search for nationally representative data on 9 indicators of physical activity was conducted and the data were assessed by an expert panel. The panel assigned grades [ie, A, B, C, D, F, or INC (incomplete)] to each indicator based on whether children across England were achieving specific benchmarks. The 2016 Report Card was produced and disseminated.
The following grades were awarded: Overall Physical Activity Levels: D-; Organized Sport Participation: D; Active Play: INC; Active Transportation: C-; Sedentary Behaviors: INC; Family and Peers: INC; School: B+; Community and the Built Environment: B; Government Strategies and Investment: INC.
The grades have not improved since the 2014 Report Card and several gaps in the literature are still present. While children’s physical activity levels remain low alongside competing sedentary choices, further national plans and investment with local actions are urgently needed to promote physical activity especially via active play, active transport, and family support.

With increasing evidence of the detrimental effects of physical inactivity, there is interest in enhancing research on policies that may influence physical activity in communities. Given the potential policy impact, a framework that organized and conceptualized policy interventions and priorities for public health efforts to promote physical activity was developed. In addition, the Physical Activity Policy Research Network (PAPRN) was formed as a way to operationalize the contents of the framework. Recommendations for future work in this area include enhancing transdisciplinary collaborations, raising the priority of policy evaluation, studying policies at all levels, and emphasizing dissemination of findings.

The Active Healthy Kids Scotland Report Card aims to consolidate existing evidence, facilitate international comparisons, encourage more evidence-informed physical activity and health policy, and improve surveillance of physical activity.
Application of the Active Healthy Kids Canada Report Card process and methodology to Scotland, adapted to Scottish circumstances and availability of data.
The Active Healthy Kids Scotland Report Card 2013 consists of indicators of 7 Health Behaviors and Outcomes and 3 Influences on Health Behaviors and Outcomes. Grades of F were assigned to Overall Physical Activity, Sedentary Behavior (recreational screen time), and Obesity Prevalence. A C was assigned to Active Transportation and a D- was assigned to Diet. Two indicators, Active and Outdoor Play and Organized Sport Participation, could not be graded. Among the Influences, Family Influence received a D, while Perceived Safety, Access, and Availability of Spaces for Physical Activity and the National Policy Environment graded more favorably with a B.
The Active Healthy Kids Canada process and methodology was readily generalizable to Scotland. The report card illustrated low habitual physical activity and extremely high levels of screen-based sedentary behavior, and highlighted several opportunities for improved physical activity surveillance and promotion strategies.
