Purpose: To examine relationships between parent perceived neighborhood recreational environment and physical activity (PA) in adolescents. Perceived diversity and proximity of recreation facilities is a core component of activity friendly neighborhood environments which may contribute to youth PA.
Methods: Participants (N=928, mean age 14.1± 1.4 years old, with 50.4% girls, 33.4 non-white/Hispanic) were ...
Purpose: Accelerometers are commonly used as an objective measure of sedentary behavior, but the method of defining nonwear time directly affects sedentary estimates. The present study examined nonwear definitions and their impact on detection of sedentary time in youth using different ActiGraph models and filters.
Methods: 60 youth (34 children and 26 adolescents; ...
Purpose: Seasonal variations in weight gain among children are well documented. Urban minority and overweight youth are at higher risk for weight gain during the summer months, which may result from decreases in physical activity (PA) and sleep. While research has established links between PA, sleep, and BMI, the current ...
Purpose: To analyze the association of the length of sedentary behavior breaks on metabolic risk score (MRS) in Portuguese adolescents (12-18 years).
Methods: In 2012 we evaluated 400 adolescents (46% males) in a school-based study. We measured cardiorespiratory fitness (20m_shuttle-run test), blood pressure, height, waist circumference, fasting glucose and insulin, total cholesterol, ...
Purpose: There is emerging evidence that sedentary behaviors are related to indices of psychosocial well-being. This study examined associations of multiple self-reported and objectively-assessed measures of time spent sedentary with adults’ life satisfaction and physical quality of life (PQOL).
Methods: Participants (N=2119; mean age=45.2yrs, SD=10.9) were recruited from neighborhoods ...
Purpose: Research has identified psychosocial factors that are consistent correlates of physical activity (PA). It is unknown whether these factors might also be related to less sedentary behavior (SB). Well-established psychosocial correlates of PA were examined to see if they related to sedentary behavior independent of PA.
Methods: Adults (n=2199) ...
Purpose: To exam the correlates of sedentary behavior in UK adults aged 65 and above.
Methods: Data were baseline assessments from a longitudinal study. Physical activity (PA) was assessed by ActiGraph GT3X for 7 days. The potential correlates such as demographics, physical health and mental health are assessed by questionnaires.
Results: ...
Purpose: To explore whether changes in objectively assessed physical activity (PA) are related to campus environmental factors among individuals living in retirement communities (RCs).
Methods: Older adults (mean age = 83, SD = 6; 72.3% female) were recruited from 11 RCs. RCs were randomized to either an attention control condition, or a multi-level walking intervention. Step ...
Purpose: To identify cross-sectional and seasonal sleeping and physical activity (PA) patterns in a community-dwelling Icelandic healthy aging population using accelerometers.
Methods: Participants (n=244, male/female 110/134, age 79.7±4.9 years, BMI 26.9±4.8 kg/m2) wore an Actiwatch Spectrum on the non-dominant wrist to assess sleep and an Actigraph GT3X on the right ...
Purpose: Little research compares physical and emotional functioning in different aging settings. We examined associations between several indicators of mental health (MH) and physical activity (PA) among older adults in three settings: Retirement communities (RCs), senior centers (SCs), and unaffiliated with a SC or RC.
Methods: Seniors in RCs (n=236), ...
