Schools were categorized as low or high SES if the median household income of the census tract in which they are located was below or above the regional

Urbanization affects lifestyles in the developing world but no studies have assessed the impact on objectively measured physical activity in children and adolescents from sub-Saharan Africa.
To compare objectively measured habitual physical activity, sedentary time, and indices of adiposity in adolescents from rural and urban areas of Kenya.
Physical activity and sedentary time were assessed by accelerometry for 5 consecutive days in 97 (50 female and 47 male) rural and 103 (52 female and 51 male) urban adolescents (mean age 13 ± 1 years). Body Mass Index (BMI) and BMI z-scores were used to assess adiposity.
Rural males spent more time in moderate-to-vigorous intensity physical activity (MVPA) compared with urban males (68 ± 22 vs. 50 ± 17 min, respectively; P < .001). Similarly, Rural females spent more time in MVPA compared with urban females (62 ± 20 vs. 37 ± 20 min, respectively; P < .001). Furthermore, there were significant differences in daily sedentary time between rural and urban subjects. Residence (rural vs. urban) significantly (P < .001) influenced BMI z-score (R 2 = .46).
Rural Kenyan adolescents are significantly more physically active (and less sedentary) and have lower indices of adiposity compared with urban adolescents and this is a likely refection of the impact of urbanization on lifestyle in Kenya.

Within this paper we “hold together” an amalgam of intensive and extensive glocalization and the simultaneous reinscription of the importance of the global growth rationalities to aid understandings of contemporary Pacific Asian sporting spectacles. Through a series of four vignettes, we point to the place of sport within intense transformations within urban conglomerations in Pacific Asia. In so doing, we point to three central, and interrelated, problematics that appear endemic to Pacific Asian mega-events; raising questions over whose histories, whose representations and which peoples matter to, and for, the Pacific Asian sporting spectacle. Conclusions are centered on attuning our scholarly directions toward the structural inequalities embedded within these processes and transformations.

Approximately 17.4% of people in Mexico self-report physical activity levels below the World Health Organization’s guidelines and an average sedentary time of 16 hours per day.1 Low physical activity has been associated with noncommunicable disease risk factors and previous research suggests that urbanicity might be an important determinant of physical activity. The aim of this study was to measure urbanicity in Mexico and assess if it is associated with physical activity and sitting time.
A sample of 2880 men and 4211 women aged 20 to 69 was taken from the 2012 Mexico National Health and Nutrition Survey and multivariable linear regression models were used to examine the association between physical activity, sitting time and urbanicity; adjusting for sex, education level, socioeconomic status and Body Mass Index. The urbanicity score and the 7 urbanicity subscores were estimated from the CENSUS 2010.
The subscores of demographic, economic activity, diversity and communication were negatively associated with physical activity. Sitting time was positively associated with the overall urbanicity, and the demographic and health subscores.
There was evidence of associations between urbanicity and physical activity in Mexico.

Geographic differences in the prevalence of physical activity (PA) have been found among adults in the US; similar studies have not been conducted among adolescents.
Using nationally representative cross-sectional data from the CDC’s 2003 Youth Risk Behavior Survey, we estimated the prevalence of PA and sedentary behaviors by metropolitan status and geographic region.
The prevalence of PA was lowest and prevalence of sedentary behavior highest for urban students. Students from the South reported the lowest prevalence of PA and the highest prevalence of TV watching, while students from the West generally reported the highest PA prevalence and lowest sedentary behavior prevalence. Prevalence differences ranged from < 1.0% to > 15%, with most differences falling between 5% and 10%.
Findings mirror regional variations previously observed in adult PA. We need to understand factors that contribute to lower PA in youth living in the South and in urban settings.

Physical activity is important for the prevention of chronic disease morbidity and mortality, and the lack of adequate levels of physical activity represents a growing public health burden around the world. The purpose of this report is to introduce the concept of the “Physical Activity Transition” and to explore the potential effects that declining physical activity levels may play on health and life expectancy as countries undergo economic and demographic changes. Physical activity is related to mortality rates in humans, and the available evidence suggests that the adoption of a lifestyle characterized by lower levels of physical activity will attenuate the expected gains in life expectancy associated with the epidemiological transition. Advances in the measurement of physical activity at work, in the home, for transport, and in leisure time in a wide variety of populations will be integral to advancing the current understanding of how macro-level factors shape physical activity patterns and patterns of morbidity and mortality.

Little is known about the role that socioeconomic status (SES) and the degree of urbanization may have on the type of barriers that the parents of Portuguese children are faced with.
