Assessing moderate to vigorous physical activity in rural West Virginia elementary school physical education classes.

BACKGROUND: Physical education (PE) provides a natural opportunity for students to be physically active during the school day; however, the amount and intensity of this activity varies. The Centers for Disease Control and Prevention recommends that students engage in MVPA for at least 50% of their PE class period. The purpose of the present study was to quantify the amount of MVPA that occurs during elementary school PE. METHODS: Accelerometer data were collected from 203 students (100 2nd grade; 103 5th grade) in 10 West Virginia elementary schools. At each school, PE teachers identified three 2nd grade classes and three 5th grade classes in which to collect the physical activity data. For each selected class, the teachers identified the first 4 students on their alphabetic roll to wear the accelerometers. PE teachers recorded the date and time of the class and the gender of the students wearing the accelerometers. RESULTS: Using 5-second epochs and Puyau's cut-offs, results indicated that, on average, students engaged in MVPA for 27% of their PE class. No significant differences were observed in MVPA between 2nd and 5th grade students or between males and females. Male and female students spent equal amounts of PE class in MVPA. CONCLUSION: Findings support policy to increase the required minimum amount of MVPA during each PE class.

Adolescent caffeine consumption and self-reported violence and conduct disorder.

Caffeine is the most widely used psychoactive substance in the world and currently the only one legally available to children and adolescents. The sale and use of caffeinated beverages has increased markedly among adolescents during the last decade. However, research on caffeine use and behaviors among adolescents is scarce. We investigate the relationship between adolescent caffeine use and self-reported violent behaviors and conduct disorders in a population-based cross-sectional sample of 3,747 10th grade students (15-16 years of age, 50.2 % girls) who were enrolled in the Icelandic national education system during February 2012. Through a series of multiple regression models, while controlling for background factors, Attention Deficit Hyperactivity Disorder symptoms and current medication and peer delinquency, and including measures on substance use, our findings show robust additive explanatory power of caffeine for both violent behaviors and conduct disorders. In addition, the association of caffeine to the outcomes is significantly stronger for girls than boys for both violent behaviors and conduct disorders. Future studies are needed to examine to what extent, if at all, these relationships are causal. Indication of causal connections between caffeine consumption and negative outcomes such as those reported here would call into question the acceptability of current policies concerning the availability of caffeine to adolescents and the targeting of adolescence in the marketing of caffeine products.

Mandatory reporting in the context of home visitation programs: intimate partner violence and children's exposure to intimate partner violence.

The mandatory reporting of intimate partner violence (IPV) is a controversial issue that is receiving increased attention. A related concern is whether children's exposure to IPV constitutes child maltreatment, making it reportable to child protective services. These issues have been relatively unexplored within the context of home visitation programs. A secondary analysis of qualitative data collected from community stakeholders, clients, and home visiting nurses in the Nurse-Family Partnership program was carried out. Participants' perceptions about mandatory reporting of IPV and reporting of children's exposure to IPV are highlighted. Emergent themes and implications for research, practice, and policy are discussed.

Effects of the built environment on physical activity of adults living in rural settings.

OBJECTIVE: To conduct a systematic review of the literature to examine the influence of the built environment (BE) on the physical activity (PA) of adults in rural settings. DATA SOURCE: Key word searches of Academic Search Premier, PubMed, CINAHL, Web of Science, and Sport Discus were conducted. STUDY INCLUSION AND EXCLUSION CRITERIA: Studies published prior to June 2008 were included if they assessed one or more elements of the BE, examined relationships between the BE and PA, and focused on rural locales. Studies only reporting descriptive statistics or assessing the reliability of measures were excluded. DATA EXTRACTION: Objective(s), sample size, sampling technique, geographic location, and definition of rural were extracted from each study. Methods of assessment and outcomes were extracted from the quantitative literature, and overarching themes were identified from the qualitative literature. DATA SYNTHESIS: Key characteristics and findings from the data are summarized in Tables 1 through 3. RESULTS: Twenty studies met inclusion and exclusion criteria. Positive associations were found among pleasant aesthetics, trails, safety/crime, parks, and walkable destinations. CONCLUSIONS: Research in this area is limited. Associations among elements of the BE and PA among adults appear to differ between rural and urban areas. Considerations for future studies include identifying parameters used to define rural, longitudinal research, and more diverse geographic sampling. Development and refinement of BE assessment tools specific to rural locations are also warranted.
