Correlates of sedentary behavior in older adults living in the UK

  • Presented on May 21, 2014

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: ...


How does retirement community environment affect changes in step counts over time?

  • Presented on May 21, 2014

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 ...


Objective measurements of free-living sleep and activity patterns in older Icelandic men and women

  • Presented on May 21, 2014

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 ...




Where does the time go? Patterns of daily PA in adolescent youth as measured by accelerometer

  • Presented on May 21, 2014

Purpose: The purpose of this study was to explore differences in daily physical activity (PA) patterns between adolescents meeting and not meeting the minimum 60-minute daily moderate to vigorous PA (MVPA) guideline. Methods: 388 adolescents (11 – 13 years) were asked to wear an Actigraph accelerometer for a 9-day period. Data sets were included ...


Effect of ACIVITAL 2-yr-intervention program on screen time, PA and fitness according to weight status and fitness levels in adolescents

  • Presented on May 21, 2014

Purpose: Compared to normal weigh and fit adolescents, overweight and unfit adolescents are more likely to develop cardiovascular disease in adulthood. Despite this, there is insufficient evidence regarding the effectiveness of general schoolbased interventions in these high-risk groups. We assessed if overweight/obese and unfit adolescents responded differently to a ...


Perceived environmental barriers as a predictor of step count changes in older adults

  • Presented on May 21, 2014

Purpose: To investigate the relationship between environmental perceptions and step counts in older adults living in retirement communities. Methods: Older adults (average age 83) were recruited from 11 retirement communities randomized to an attention control condition or a walking intervention that addressed environmental barriers. 7-day step counts were measured at baseline and 3 ...



Associations between neighbourhood typologies and MVPA and sedendtary time

  • Presented on May 21, 2014

Purpose: Most studies of neighbourhood features examine singular neighbourhood attributes, which may pattern in different ways. This study aimed to identify typologies of neighbourhood attributes and their associations with physical activity among children. Methods: The homes of 808 children aged 5-6 and 10-12 years were mapped in a Geographic Information System. ...
