Background: Growing evidence suggests that the broader neighborhood socioeconomic environment is independently associated with cardiometabolic health. However, few studies have examined this relationship among younger populations. Purpose: The purpose of the study was to (1) investigate the association between neighborhood socioeconomic deprivation (SED) and cardiorespiratory fitness and (2) determine the extent to which physical activity mediates this relationship. Methods: Data from 312 youth (aged 12–15 y) were obtained from the 2012 National Health and Nutrition Examination Survey National Youth Fitness Survey. Cardiorespiratory fitness was measured using a standard submaximal treadmill test, and maximal oxygen consumption was estimated. Physical activity was self-reported time spent in moderate to vigorous activity. Neighborhood SED was measured by a composite index score at the census tract of residence. Logistic regression analyses examined relationships between neighborhood SED, physical activity, and cardiorespiratory fitness, adjusting for individual-level characteristics and the complex sampling design. Results: Neighborhood SED was not significantly associated with cardiorespiratory fitness or physical activity among youth in the study sample. Conclusions: While not significant, cardiorespiratory fitness levels were observed to decrease as neighborhood SED increased. Future research is needed to better understand this relationship and to identify underlying mechanisms beyond fitness or physical activity that may drive the relationship between neighborhood SED and health.

Background:

The aims of this study were to describe the physical activity levels of girls during dance classes and to identify factors associated with moderate-to-vigorous physical activity (MVPA) in those classes.

Methods:

Participants were 137 girls (11 to 18 years-old) enrolled in ballet, jazz, or tap dance classes from 11 dance studios. Participants wore an accelerometer during the selected dance class on 2 separate days. Factors hypothesized to be associated with MVPA were dance style, instructional level, instructor’s experience, percent of class time spent in choreography, and participants’ age, race/ethnicity, BMI-for-age percentile, and years of dance training. Data were analyzed using generalized linear mixed models.

Results:

Girls engaged in 9.8 minutes of MVPA, 6.0 minutes of moderate, 3.8 minutes of vigorous, 39.3 minutes of light, and 10.9 minutes of sedentary behavior per hour of dance class participation. Jazz/tap classes provided more MVPA than ballet classes, and intermediate level classes provided more MVPA than advanced level classes. Girls with more dance training obtained more MVPA than girls with less dance training.

Conclusion:

Dance classes provide valuable opportunities for adolescent girls to be physically active.

Background:

Efforts to increase population levels of physical activity are increasingly taking the form of strategic plans at national, state/regional, and local levels. The processes employed for developing such plans have not been described previously. The purpose of this article is to chronicle the processes employed in and lessons learned from developing the US National Physical Activity Plan (NPAP).

Methods:

The Coordinating Committee oversaw development of the NPAP. Key steps in the process included creating a private–public coalition based in the private sector, organizing the NPAP around 8 societal sectors, reviewing the evidence base for promotion of physical activity in each sector, conducting a national conference to initiate development of the NPAP’s core content, ensuring broad participation in developing and refining the NPAP, and launching the NPAP through a press event that attracted national attention.

Results and Conclusion:

The 3-year effort to develop the NPAP was guided by a private–public collaborative partnership involving private sector organizations and government agencies. Launched in May 2010, the NPAP included more than 250 evidence-based recommendations for changes to policy and practice at the national, state, and local levels across 8 societal sectors.

Field tests of upper body muscular strength and endurance (UBMSE) are often administered to children, but little is known about the determinants of performance on these tests. Therefore the purpose of this investigation was to examine potential determinants of performance on several common field tests of UBMSE including pull-ups, flexed-arm hang, push-ups, and two types of modified pull-ups. Subjects were 56 girls and 38 boys, ages 9 to 11 years. Potential determinants assessed were age, height, weight, gender, % fat, physical activity, and laboratory measures of muscular strength and endurance. Multiple regression analysis revealed that the laboratory measures of UBMSE failed to account for significant fractions of variance in performance on four of the five tests. However, % fat was significantly associated with performance on four of five tests. These results indicate that factors other than muscular strength and endurance account for most of the variance in performance, and that % fat appears to be a particularly important determinant of performance.

This paper reviews the descriptive epidemiology of physical activity in adolescents. Large population-based studies were reviewed, along with smaller studies using objective monitoring of physical activity. Estimates showed that adolescents engage in physical activity of any intensity for a mean of one hour per day. Approximately two thirds of males and one quarter of females participate in moderate to vigorous activity for 20 min 3 or more days per week. Activity levels decline with increasing age across adolescence, and this decrease is more marked in females than in males. Comparison of these data to physical activity guidelines for adolescents suggests the vast majority are meeting the guideline of accumulating physical activity. However, a substantial number of males, and the majority of females, are not meeting the guideline for moderate to vigorous physical activity.

Background:

Architects of the United States national physical activity plan can benefit from a thorough understanding of national physical activity plans from other nations. The purpose of this paper was to search for and analyze comprehensive national physical activity plan documents that can best inform the development of the U.S. plan.

Methods:

Electronic databases were searched for national physical activity plan documents, yielding 252 documents from 56 countries. After eliminating documents that were not written in English, did not address physical activity primarily, and did not meet our definition of a national physical activity plan, we were left with physical activity plans from 6 countries—Australia, United Kingdom, Scotland, Sweden, Northern Ireland, and Norway.

Key recommendations:

Architects of the U.S. plan can learn as much from what was present in many documents as from what was absent. Examples of recommended components of national plans have been identified and highlighted for each of the 6 countries. Missing from all but 1 national plan document was a detailed process for accountability. Providing a clear path and detailed process of accountability will assist greatly in measuring short- and long-term success of the U.S. plan.
