Harris, Tess; Kerry, Sally M.; Victor, Christina R.; Ekelund, Ulf; Woodcock, Alison; Iliffe, Steve; Whincup, Peter H.; Beighton, Carole; Ussher, Michael; Limb, Elizabeth S.; David, Lee; Brewin, Debbie; Adams, Fredrika; Rogers, Annabelle; Cook, Derek G. (Journal article; Peer reviewed, 2015-02-17)Background: Brisk walking in older people can increase step-counts and moderate to vigorous intensity physical activity (MVPA) in ≥10-minute bouts, as advised in World Health Organization guidelines. Previous interventions ... -
Cross-sectional study of ethnic differences in physical fitness among children of South Asian, black African–Caribbean and white European origin: the Child Heart and Health Study in England (CHASE)
Nightingale, C. M.; Donin, A. S.; Kerry, S. R.; Owen, C. G.; Rudnicka, Alicja R.; Brage, Søren; Westgate, Kate L.; Ekelund, Ulf; Cook, Derek G.; Whincup, Peter H. (Journal article; Peer reviewed, 2016)Objective: Little is known about levels of physical fitness in children from different ethnic groups in the UK. We therefore studied physical fitness in UK children (aged 9–10 years) of South Asian, black African–Caribbean ... -
Effect of a primary care walking intervention with and without nurse support on physical activity levels in 45- to 75-year-olds: The pedometer and consultation evaluation (PACE-UP) cluster randomised clinical trial
Harris, Tess; Kerry, Sally M.; Limb, Elizabeth S.; Victor, Christina R.; Iliffe, Steve; Ussher, Michael; Whincup, Peter H.; Ekelund, Ulf; Fox-Rushby, Julia; Furness, Cheryl; Anokye, Nana; Ibison, Judith; DeWilde, Steve; David, Lee; Howard, Emma; Dale, Rebecca; Smith, Jamie; Cook, Derek G. (Journal article; Peer reviewed, 2017-01-03)Pedometers can increase walking and moderate-to-vigorous physical activity (MVPA) levels, but their effectiveness with or without support has not been rigorously evaluated. We assessed the effectiveness of a pedometer-based ... -
Effect of pedometer-based walking interventions on long-term health outcomes: Prospective 4-year follow-up of two randomised controlled trials using routine primary care data

(Peer reviewed; Journal article, 2019)Background: Data are lacking from physical activity (PA) trials with long-term follow-up of both objectively measured PA levels and robust health outcomes. Two primary care 12-week pedometer-based walking interventions in ... -
Evaluation of reliability and validity of the General Practice Physical Activity Questionnaire (GPPAQ) in 60–74 year old primary care patients
Ahmad, Shaleen; Harris, Tess; Limb, Elizabeth S.; Kerry, Sally; Victor, Christina; Ekelund, Ulf; Iliffe, Steve; Whincup, Peter; Beighton, Carole; Ussher, Michael; Cook, Derek G. (Journal article; Peer reviewed, 2015-09-02)BACKGROUND: GPPAQ (General Practice Physical Activity Questionnaire) is a self-assessment physical activity questionnaire widely used in primary care. Reliability and validity data in older people are lacking. The ... -
Interpreting population reach of a large, successful physical activity trial delivered through primary care
Kerry, Sally M.; Morgan, Katy E; Limb, Elizabeth S.; Cook, Derek G.; Furness, Cheryl; Carey, Iain; DeWilde, Stephen; Victor, Christina R.; Iliffe, Steve; Whincup, Peter; Ussher, Michael; Ekelund, Ulf; Fox-Rushby, Julia; Ibison, Judith; Harris, Tess (Journal article; Peer reviewed, 2018)Background: Failure to include socio-economically deprived or ethnic minority groups in physical activity (PA) trials may limit representativeness and could lead to implementation of interventions that then increase health ... -
Measuring change in trials of physical activity interventions: A comparison of self-report questionnaire and accelerometry within the PACE-UP trial 11 Medical and Health Sciences 1117 Public Health and Health Services
Limb, Elizabeth S.; Ahmad, Shaleen; Cook, Derek G.; Kerry, Sally M.; Ekelund, Ulf; Whincup, Peter H.; Victor, Christina R.; Iliffe, Steve; Ussher, Michael; Fox-Rushby, Julia; Furness, Cheryl; Ibison, Judith; DeWilde, Stephen; Harris, Tess (Peer reviewed; Journal article, 2019)Background: Few trials have compared estimates of change in physical activity (PA) levels using self-reported and objective PA measures when evaluating trial outcomes. The PACE-UP trial offered the opportunity to assess ... -
Physical activity levels in adults and older adults 3–4 years after pedometer-based walking interventions: Long-term follow-up of participants from two randomised controlled trials in UK primary care
