Background:

A cross-country profile of physical activity and sedentary behavior is lacking within Eastern Mediterranean region (EMR) counties. The objectives were to examine prevalence of physical activity and sedentary behavior among adolescents of 10 EMR countries, and to describe potential differences in the 2 factors by sex, age, and BMI.

Methods:

A total of 23,562 adolescents were included from 10 EMR counties based on completeness of data (physical activity, sedentary behavior, age, sex, weight and height) from the Global school-based student health survey (GSHS).

Results:

Overall prevalence of physical activity (19%) is low and sedentary behavior is high (29%), with significant differences among counties. Oman had the highest (26%) and Egypt had the lowest (9%) prevalence of active students. Prevalence of sedentary behavior was the highest in United Arab Emirates (40%) and lowest in Pakistan (8%). Physical activity was lower and sedentary behavior was higher among female adolescents. A linear trend was observed between BMI and both physical activity and sedentary behavior; a similar pattern was seen with age.

Conclusions:

There is a need for interventions to increase the prevalence of adolescents meeting physical activity recommendations in the 10 countries. More investigation is required to understand the cultural context of sex and BMI influence on activity patterns.

and the International Diabetes Federation. 5 Because of these varying definitions, the true prevalence of MetS is uncertain. In general, the prevalence of MetS varies between 34% and 39% in developed countries. 6 Among developing nations, the prevalence is estimated to be between 16% and 32%. 7 In

“Gaps in Our Knowledge” are discussed in the context of the need to integrate biological and behavioral factors in a biocultural approach to physical activity and movement proficiency. Specific issues considered include outdoor play, organized and informal activity, biological maturation, tracking of activity, development of movement proficiency, and individual differences. Studies considered are largely based on youth in economically better-off, developed countries in the western culture context. There is a need to extend studies of physical activity and movement proficiency to different cultural contexts.

The purpose of the 2008 Earle F. Zeigler Lecture was to highlight some of the issues involved in the globalization of sport that affect the field of sport management. In particular, four issues were presented: a division of labor undertaken on an international scale where transnational corporations are drawing on developing countries’ work forces to manufacture sportswear and sport equipment; the increasing flow of athletes where country of birth and origin are no longer a limitation on where an athlete plays and competes; the increased involvement of global media conglomerates in sport; and the impact of sport on the environment. The impact and inconvenient truths of these issues on sport management were addressed.

Background:

National and international strategies to increase physical activity emphasize environmental and policy changes that can have widespread and long-lasting impact. Evidence from multiple countries using comparable methods is required to strengthen the evidence base for such initiatives. Because some environment and policy changes could have generalizable effects and others may depend on each country’s context, only international studies using comparable methods can identify the relevant differences.

Methods:

Currently 12 countries are participating in the International Physical Activity and the Environment Network (IPEN) study. The IPEN Adult study design involves recruiting adult participants from neighborhoods with wide variations in environmental walkability attributes and socioeconomic status (SES).

Results:

Eleven of twelve countries are providing accelerometer data and 11 are providing GIS data. Current projections indicate that 14,119 participants will provide survey data on built environments and physical activity and 7145 are likely to provide objective data on both the independent and dependent variables. Though studies are highly comparable, some adaptations are required based on the local context.

Conclusions:

This study was designed to inform evidence-based international and country-specific physical activity policies and interventions to help prevent obesity and other chronic diseases that are high in developed countries and growing rapidly in developing countries.

Background:

It is speculated that rural Kenyan children are more physically active than those in developed countries. The purpose of this study was to examine pedometer-measured physical activity levels of western Kenyan youth.

Methods:

Participants in this study were children in Levels 3 and 5 who attended a private primary school. The sample (n = 72) consisted of 43 girls and 29 boys (average age = 9.8 ± 1.1, range = 8−12 years). Age, gender, tribe, and height and weight measures were collected. Weight status category was determined according to CDC guidelines. Participants wore a sealed Yamax pedometer for 4 weekdays during the measurement period. Data analysis included descriptive statistics and 2-way ANOVA (age × gender).

Results:

The total sample averaged 14558 ± 3993 daily steps. There was no significant effect for age [F(4,68) = 1.682, P = .102] nor significant age × gender interaction [F(4,68)=1.956, P = .117]. There was a significant effect for gender [F(1,68) = 4.791, P = .033], with boys (16262 ± 4698) significantly more active than girls (13463 ± 3051).

Conclusions:

The observed daily steps are higher than those observed in the U.S., similar to samples in other developed countries, but lower than Amish youth.

Intake of dietary supplements is widespread among athletes in developed countries. This study evaluated the use of dietary supplements in athletes from a developing country. Dietary supplementation practices of 113 national-level athletes age 15–35 yr in Sri Lanka were assessed. All athletes from track-and-field, badminton, football, swimming, cycling, and karate squads who consented to participate in the study were administered an anonymous questionnaire by an interviewer. Information on number of supplements taken, frequency of use, nature of product, rationale, sources of advice, and reasons for taking supplements was obtained. Most athletes (94%) consumed dietary supplements. On average, 3.7 products/day were consumed. Footballers had significantly lower intake of supplements than other athletes (footballers 71%, others 98%; p < .05). They also consumed fewer products per day (footballers 0.7, others 3.5; p < .05). Popular supplements included multivitamins, vitamin E, calcium, energy foods and drinks, and creatine. Multiple supplement use was common, with 29% athletes taking 4 products/day. The athletes sought advice on supplement use from sports doctors (45%), team coaches (40%), or friends (15%). Most took supplements to improve performance (79%), and 19% claimed to take supplements to improve their overall health status. Dietary supplement use is widespread among national-level Sri Lankan athletes. The ad hoc use of supplements indicates that educational intervention in the sporting community is essential.

The know-how is available to reverse the obesity epidemic. Reversing obesity is a societal necessity because it is the predominant contributor to chronic ill health in developed countries and a growing precipitant of illness in middle and low-income countries. In the United States, for example, obesity is the chief driver of health care costs in a country that can no longer afford health care. Although some might advocate population-wide medication use to mitigate the effects of obesity on health, the more direct response is to end obesity. The goal of this paper is explain how mass-scalable obesity containment can be designed, built, and disseminated. Scalable Obesity Solutions (S.O.S.) are discussed from concept through deployment.

This research analyzes a strategic approach to managing surf tourism in Papua New Guinea (PNG). Surf tourists travel to often remote destinations for the purpose of riding surfboards, and earlier research suggests the mismanagement of surf tourism in some destinations has resulted in significant deleterious impacts on host communities. The research question in this study addresses how surf tourism can be managed to achieve sustainable host community benefits in the context of a developing country. Primary data came from semistructured interviews and participant observation. The findings demonstrate how sport governing bodies can engage host communities in a collaborative framework for the sustainable utilization of sport tourism resources. The derived knowledge from this research may decrease host communities’ reliance on less sustainable commercial activities, and inform policy and practice on sustainable approaches to using sport tourism for community building and poverty alleviation.

Background:

Prospective studies on physical activity (PA), diet, and body composition in adolescents are lacking, particularly outside high-income countries.

Goals:

To describe the methods used to assess these variables in the 1993 Pelotas (Brazil) Birth Cohort and to discuss the fieldwork challenges faced and alternatives to overcome them.

Methods:

In 2006–07 a subsample of the 1993 Pelotas cohort was revisited. PA was estimated using questionnaires, a combined heart-rate and motion sensor (Acti-Heart), and the ActiGraph GT1M accelerometer. Diet was investigated by questionnaire. Total body water was determined by stable isotopes. Thirty individuals had their total energy expenditure assessed by doubly labeled water. All data were collected at participants’ home.

Results:

The logistics of the fieldwork and the difficulties in undertaking the study and alternatives to overcome them are presented. Preliminary analyses show that 511 individuals were traced (response rate = 90.0%). Compliance of both adolescents and their families for the motion sensors and body-composition measurements was excellent.

Conclusions:

The authors conclude that it is feasible to carry out high-quality studies on PA in developing countries. They hope the article will be useful to other researchers interested in carrying out similar studies.
