- PURPOSE: The aim of this cross-sectional study was to describe and analyze accelerometer-measured sedentary time and physical activity (PA) among adolescents in a multicultural area characterized by low socioeconomic status (SES). METHOD: Seventh-graders (n=114 (girls n=66), mean age: 12.8±0.5 y) were recruited from three schools in a multicultural area of the city of Gothenburg, Sweden. Sedentary time and PA were measured with ActiGraph™ accelerometers. RESULT: Of total wear-time, 70 (±6)% was sedentary, with girls being more sedentary than boys. Girls had less light PA (LPA) and moderate-to-vigorous PA (MVPA) than boys. Similar patterns were shown during in-school and out-of-school hours. During wear-time, 53% had a mean of ≥60 min of MVPA per day, but only 6% of the girls and 24% of the boys were sufficiently physically active every day. Girls had more sedentary bouts of ≥10 min and fewer MVPA bouts of ≥5 min per day than boys. Those who participated in organized sports spent a mean of 15 more minutes of MVPA per day compared to those who did not. No association was observed between body mass index (BMI) and sedentary time and PA. CONCLUSION: Only a few adolescents from a Swedish multicultural area characterized by low SES met the PA recommendations every day, and girls were more sedentary and less physically active than boys. Adolescents involved in organized sports had more of MVPA per day than their non-involved peers. Sedentary time and PA were not related to BMI.

- Aim: Physical conditioning of youth has always been a controversial topic as it raises ethical, physiological, and medical issues. Current recommendations and guidelines suggest that strength training is a relatively safe and worthwhile method in conditioning youth. This, however, requires well-informed coaches who follow age-appropriate strength training recommendations and guidelines, compiles well-designed strength training programs, and provides qualified supervision and instructions. The purpose of this study was to investigate coaches’ awareness of current recommendations and guidelines regarding strength training for youth.Method: A total of 39 football (US: soccer) coaches (34 males and 5 females) training boys in age groups 8–12 years were included in this study. Data were collected using an attitude statement questionnaire, and the assertions were based upon current recommendations and guidelines.Results: The results revealed significant differences among coaches in terms of knowledge of important aspects of strength training for youth.Conclusions: The results suggested that coaches in the present study were not aware of the latest recommendations and guidelines regarding strength training for youth.

- BACKGROUND: Physical activity provides fundamental health benefits and plays a positive role in physical well-being. The aim of this present study was to investigate whether a 6-month physical activity program could influence physical self-esteem and frequency of physical activity in physically inactive female high school students in short- and long-term periods and whether personality traits were related to physical activity behaviour and compliance with the program. METHODS: The study was a cluster-randomised controlled intervention study including 104 physically inactive female high school students aged 16-19 years, 60 females in an intervention group and 44 females in a control group. The intervention group exercised at sport centres at least once per week during a 6-month period. Questionnaires were used for evaluation. RESULTS: At a 6-month follow up, the intervention group improved physical self-perception in all subdomains and significantly improved physical condition, physical self-worth and self-related health compared to the control group. At 1-year follow up, 25 females out of 53 females were still physically active, and all ratings remained almost the same as at the 6-month follow up. There were no particular personality traits that were dominant in the groups. CONCLUSION: A 6-month physical activity program can positively influence physical self-esteem and the frequency of physical activity, both from a short- and long-term perspective.

- BACKGROUND: The use of tobacco products among adolescents in Southeast Asia represents a major public health burden. Two out of ten adolescents attending school are tobacco users and several factors influence them to initiate tobacco use. Most studies related to tobacco use are quantitative, whereas qualitative studies exploring adolescents' smoking behavior and their views, knowledge and experiences are scarce.OBJECTIVE: To gain a deep understanding of Nepalese adolescents' knowledge and opinions about smoking and reasons for smoking initiation.SUBJECTS: Adolescents from four secondary schools in the Bhaktapur district, Nepal.METHODS: Eight focus-group discussions were conducted with 71 adolescents aged 13-16 years and from grades 8-10. Data were analyzed using manifest qualitative content analysis.RESULTS: The participants knew that smoking represents health risks as well as socio-economic risks, but few described the addictive nature of tobacco and health risks related to passive smoking. Most participants related smoking initiation to the smoking behavior of peers and family members, but easy accessibility to cigarettes, ineffective rules and regulations, and exposure to passive smoking also created environments for smoking. Some expressed confidence to resist peer pressure and refuse to start smoking, but also expressed the need for prevention strategies in schools and for governmental initiatives, such as more strict implementation of tobacco control and regulations to prevent and reduce smoking.CONCLUSION: Curbing the tobacco epidemic in Nepal requires healthy public policies and multifaceted interventions to address the knowledge gap on health consequences associated with smoking among adolescents, teachers and parents/adults.

- Objectives To compare self-perceived global self-esteem (GSE) and physical self-esteem (PSE) among children and adolescents aged 11 and 14 years in Southeastern Sweden, investigated in 2000 and 2017. Methods The present study consists of two independent cross-sectional study-cohorts from Southeastern Sweden, investigated in 2000 and 2017. The same protocol, procedures, and instruments were used in 2000 and 2017. In October 2000, data for self-perceived GSE and PSE, and anthropometry were collected from 11-years old children (Grade 5) (n=74) and 14-years old adolescents (Grade 8) (n=84). In October 2017, children (n=186) and adolescents (n=140) from the same grade-levels, schools and classrooms provided data for the same variables as in 2000. GSE and PSE were assessed with the Children and Youth Physical Self-Perception Profile (CY-PSPP). Results Self-perceived GSE was higher in 2017 as compared to 2000 among both 11-years old boys (p<0.001) and girls (p<0.001) and 14-years old boys (p=0.008) and girls (p<0.001). Similarly, self-perceived PSE was higher in 2017 as compared to 2000 among both 11-years old boys (p<0.001) and girls (p=0.023) and 14-years old boys (p=0.025) and girls (p=0.002). Conclusions Self-perceived GSE and PSE among children and adolescents aged 11 and 14 years in Southeastern Sweden were higher in 2017 as compared to 2000. These results are not in agreement with the increased psychological ill-health as being reported among children and adolescents during the last decade in Sweden.

- Introduction: One variable that has been consistently associated with adolescents’ physical activity is perceived activity competence. Perceived physical (or sport) competence is considered a sub-domain to the physical self-esteem or self-worth (i.e., a person’s valuation of what is good and worthy in their self-description).Objective: This study aimed to describe levels of and inter-correlations among physical self-esteem, physical activity, and body mass index in a longitudinal design spanning adolescence to early adulthood.Materials and methods: At mean ages of 12.7, 15.7, 17.7 and 22.7 years, we measured perceived physical self-esteem in 39 (22 boys) Swedish adolescents. Physical activity (steps/day) for four consecutive schooldays, height, and weight were also measured.Results: No significant difference between the four time points for any variable of perceived physical self-esteem was seen, neither in boys nor girls. In general, all physical self-variables revealed non-linear trajectories across time, where the general trend was an increase during the younger ages followed by a decrease during older ages. At ages 12 and 15 years in boys and girls physical condition and physical strength as well as body attractiveness and physical strength, respectively, had the strongest correlations to physical self-esteem. At age 17 and 22 years sports competence had the strongest correlation to self-esteem in girls, while body attractiveness and physical strength had the strongest correlation to self-esteem in boys.Conclusion: An overall stability in physical self-esteem was found. However the impact of a sub-domain upon physical self-esteem vary during adolescence and early adulthood. Such information may be useful when creating physical activity programs that support and develop physical self-esteem.

- Background: Active travel has a potential to increase children ' s physical activity (PA). Pedometers offer a valid option to measure PA, but do not capture cycling activity. Children ' s self-reported cycling distances can be analyzed by the Geografic Information System (GIS). Aim: To combine pedometry and GIS mapping to identify the relative amount of cycling in children ' s PA. Study group: Of all children in 4th grade (n = 187) in Staffanstorp Sweden, 144 had valid pedometer data. Fifty-six children were non-cyclists while 88 children (32 boys, 47 girls, 9 gender unknown) reported at least one cycle journey. Methods: Cycle trips were entered into GIS and calculated to total cycling distance. Average length of the single distances cycled per day was 676 m (SD = 534 m). A previously reported cycling speed (13.5 km/h) was used to calculate time spent cycling. Consequently distance = 676 m, speed = 13.5 km/h = 13,500 m/3600 s = 3.75 m/s and time = 676m/3.75m/s = 180.26 s = 3 min. Expenditure of 4 and 5 metabolic equivalents (METs) has in children been reported equivalent to 122 and 127 steps/min, respectively. We estimated 4.7 METs (13.5 km/h) as 126 steps for every min of cycling (127 - 122 = 5 ×?0.7 = 125.5). Results: The daily mean cycle distance was 676 m, on average 379 additional steps/day for cycling children (min. 21, max. 1385, SD = 299) with no gender difference. Additional " steps " obtained by cycling corresponded to on average 3 % of their PA. Conclusion: The relative contribution of cycling in 10-yearold children ' s PA level is quite small and stable between children across different levels of activity levels, regardless of gender. © 2013 Walter de Gruyter GmbH.
