Background:Different approaches to measuring physical activity and fatness in youth have resulted in studies reporting relationships ranging from very strong to nonexistent.Methods:The sample comprised 787 boys and 752 girls between the ages of 7 and 16 years. Pedometer-determined physical activity, height, weight, and waist girth measures were taken.Results:Significant differences were found in activity level between body mass index-determined weight categories for the girls (F1,742 = 9.07, P = .003) but not for the boys (F1,777 = 3.59, P = .06) and between truncal adiposity groupings for the boys (F1,777 = 4.69, P = .03) and the girls (F1,742= 13.56, P = .000).Conclusions:The relationship between physical activity and body fatness differs according to the measure used and between boys and girls. Factors contributing to body fatness such as eating behaviors or sedentary activities might be more important among boys than girls.

AbstractObjectivesThe Health-promotion through Obesity Prevention across Europe (HOPE) project aims to bring the European scientific knowledge on overweight, obesity and their determinants together and use the expertise of researchers across Europe to contribute to tackling the obesity epidemic.Design/subjects/resultsThis special issue of Public Health Nutrition presents important results from one of the work packages of the HOPE project that aims at gaining and integrating knowledge on the determinants of nutrition, physical activity and obesity among schoolchildren and adolescents (aged 10–18 years) in different European regions. It includes contributions from Northern Europe (Norway), Central and Eastern Europe (Germany, Poland and the Czech Republic), Southern Europe (Greece) and Western Europe (Belgium and The Netherlands), as well as an overview of the availability of good-quality data on prevalence rates and trends in overweight (including obesity) among adolescents in European Union (EU) countries. The studies that are included report prevalence differences, data on relevant nutrition and physical activity behaviours, as well as potential physical and environmental behavioural determinants.ConclusionThese papers provide further evidence on differences in obesity and overweight prevalence among different EU regions and countries, and contribute to the further exploration of risk factors that may or should be addressed in obesity prevention efforts for school-aged children and adolescents in EU countries.

AbstractBackground: The purpose of the research was to check opinions of students of various stages of education in the Pomeranian province about the attractiveness of Nordic Walking in comparison with other activities.Material/Methods: About 500 intentionally selected students participated in the survey. These were students of 11-18 years of age. Half of them participated in Nordic walking PE lessons. The researched students’ schools were localized in the Pomeranian province in Poland. Methods of a diagnostic survey using two questionnaires were applied. The first one was used to assess the level of students’ physical activity and was also used to research health behaviours of children and adolescents in Europe (HBSC). The second one - our own - was created to asses the attractiveness of Nordic walking. In the first part, the subjects ranked Nordic walking in comparison with other forms of physical activity. In the second part, they declared eagerness to attend such lessons.Results: The collected data imply a vast diversity of students’ opinions about the attractiveness of Nordic walking in comparison with other forms of physical activity and indicate the need to do research in the area of students’ preferences in planning PE lessons at school.Conclusions: It seems that in subsequent years of education, NW will gain followers among this group because it is a natural form of movement, whose health effects are starting to be seen not only by teachers but also by students

Children’S Sleep

Abstract Objectives and background Social demands of the school-year and summer environment may affect children’s sleep patterns and circadian rhythms during these periods. The current study examined differences in children’s sleep and circadian-related behaviors during the school-year and summer and explored the association between sleep and circadian parameters and change in body mass index (BMI) during these time periods. Methods This was a prospective observational study with 119 children ages 5 to 8 years with three sequential BMI assessments: early school-year (fall), late school-year (spring), and beginning of the following school-year in Houston, Texas, USA. Sleep midpoint, sleep duration, variability of sleep midpoint, physical activity, and light exposure were estimated using wrist-worn accelerometry during the school-year (fall) and summer. To examine the effect of sleep parameters, physical activity level, and light exposure on change in BMI, growth curve modeling was conducted controlling for age, race, sex, and chronotype. Results Children’s sleep midpoint shifted later by an average of 1.5 h during summer compared to the school-year. After controlling for covariates, later sleep midpoints predicted larger increases in BMI during summer, (γ = .0004, p = .03), but not during the school-year. Sleep duration, sleep midpoint variability, physical activity levels, and sedentary behavior were not associated with change in BMI during the school-year or summer. Females tended to increase their BMI at a faster rate during summer compared to males, γ = .06, p = .049. Greater amounts of outdoor light exposure (γ = −.01, p = .02) predicted smaller increases in school-year BMI. Conclusions Obesity prevention interventions may need to target different behaviors depending on whether children are in or out of school. Promotion of outdoor time during the school-year and earlier sleep times during the summer may be effective obesity prevention strategies during these respective times.

Abstract Objectives This systematic and meta-analysis review was conducted to determine the status of Iranian children and adolescents’ physical activity. Content All the related articles which were published in the major databases, including Pubmed, Scopus, Web of Science, Embase, Magiran, SID from the beginning of 2010 to the end of 2019, were reviewed by researchers. The Newcastle-Ottawa scale was also used to evaluate the quality of articles. Moreover, I 2 index and chi-square were used to assess the heterogeneity between the results. Summary 490 articles were found as a result of the search in the selected international and local databases, where finally, 10 articles were included into the meta-analysis after the elimination of the duplicated articles and applying inclusion and exclusion criteria. The results indicated that 29.5% of the girls were considered active according to WHO criteria (16.1–42.8: 95% CI) and also 20.5% of the boys (7.3–33.7: 95% CI). Outlook Overall, this study’s findings showed that a large percentage of Iranian children and adolescents do not achieve the level of physical activity recommended by the World Health Organization. This can lead to undesirable consequences for this group of population that is considered as the human capital of any country; consequently, it seems necessary to take basic measures at the micro and macro levels in order to reduce such problems in the society.
