Identifying the built-environment attributes that may reduce vehicular sitting time can inform future initiatives linking the public health, urban design, and transportation sectors. Data collected in 20...
Clustering of risk factors for noncommunicable diseases in Brazilian adolescents: prevalence and correlates.
We evaluated the clustering of risk factors and their associations with sociodemographic variables. We used a cross-sectional study carried out in 2011 comprising 1132 students aged 14-19 years from Santa Maria, Brazil. The cluster index was created as the sum of the risk factors. For the correlates...

Steps that count: the association between the number and intensity of steps accumulated and fitness and health measures.
We aim to examine this relationship. A convenience sample (N = 70, 35 men, 32 ± 8yrs) wore a pedometer (4 days). The pedometer classified steps as "aerobic" (≥ 60 steps/minute, minimum duration of 1 minute) or "non-aerobic" (< 60 steps/minute and/or < 1 minute). Estimated maximal oxygen uptake (VO2m...
Associations between breaks in sedentary time and body size in Pacific mothers and their children: findings from the Pacific Islands Familie...
Breaks in sedentary behavior are associated with reduced body size in general populations. This study is the first to consider the relationship between objectively assessed sedentary breaks and body size in Pacific children and their mothers. Pacific children aged 6 years (n = 393) and their mothers...
Patterns of noncompliance in adolescent field-based accelerometer research.

Evaluation of school transportation patterns and the associated impact on BMI in 2 Midwestern communities.
The decline in active commuting to and from school in the United States is, in part, due to urban design standards and public policies that promote automobile travel and discourage pedestrian activity. The current investigation examines active commuting at neighborhood schools and how it is altered...
Neighborhood walkability and walking behavior: the moderating role of action orientation.
In promoting physical activity, it is important to gain insight into environmental factors that facilitate or hinder physical activity and factors that may influence this environment-behavior relationship. As the personality factor of action orientation reflects an individual's capacity to regulate...
