Question Answer
Definition of surveillance/monitoring Surveillance is the ongoing collection, analysis and use of health data for the planning, implementation, and assessment of disease control “Information for action”
What are the 4 primary purposes of population monitoring • Prevalence - is there a problem? • Trends - is it getting worse/better? • Programme planning and targeting - what should be done, which population groups, address inequalities? • Evaluation - have strategies to intervene made a difference, have population PA levels increased?
What does effective population measurement allow• Baseline prevalence of physical activity (PA) to be assessed • Assessment of trends over time for tracking national targets • Tracking of PA patterns throughout the lifespan • Identification of subgroups at high risk • Development of population-specific PA interventions • Evaluation of interventions, policies and programmes • Budgeting of public health resources
How do we monitor the population• Collect data from a large representative sample and extrapolate to estimate the whole population • Repeat over time to obtain trend data • Methods and measures MUST remain the same!
Methodological issues of population monitoring – Which sampling frame to use (to get a representative sample)? – What mode of data collection and which instrument? – Over what timeframe (weeks, months, year(s))? – Cost?
What are the 5 key large scale population surveys • Allied Dunbar National Fitness Survey (1990) • Health Survey for England (since 1991 – ongoing) • Active People – Sport England (2005/6-2015/16) • Active Lives – Sport England (2015/16 – ongoing) • National Travel Survey (1995 - ongoing)
