The Oxford Health Alliance Background Non-communicable diseases (NCDs) account for 60% of all deaths globally, with 80% occurring in low and middle income countries Four NCDs are largely responsible; cardiovascular disease, chronic respiratory disease, cancer and diabetes These diseases are preventable. Approximately 80% could be prevented by addressing the main risk factors The three main risk factors are tobacco use, unhealthy diet and physical inactivity Action Plan, WHO 2010
The Oxford Health Alliance Individual or Community Interventions? Traditionally, medical research investigating risk of NCD targets the at-risk individual Randomised controlled trail are conducted, comparing an intervention group with a control group Effective interventions at the individual level are identified These individual-level behaviour change interventions are often unsuccessful at community or population level The challenge is to find a way to change the environment to promote health and reduce risk of disease
The Oxford Health Alliance Community Interventions for Health (CIH) CIH is the largest and most comprehensive multinational collaborative study for community interventions ever undertaken The long-term goal of the CIH study is to create sustainable interventions that prevent and control the leading chronic diseases by addressing the three main risk factors CIH aims to develop, evaluate and showcase sustainable interventions in addressing tobacco use, unhealthy diet and physical inactivity in communities

The Oxford Health Alliance Study design In each study area, an intervention and control site has been selected for comparison Baseline data have been collected from all sites and comprise: -Questionnaires from a sample of the population -Biometrics from a sub-sample -Environmental scans Interventions have been implemented Final data collection for comparison with baseline will be collected at the end of 2011

The Oxford Health Alliance Interventions – improving diets to reduce obesity in Mexican school children School meals are not routinely provided in Mexican schools Many children eat snacks and fast food from vendors Parents in some schools have begun to cook and provide healthy meals
The Oxford Health Alliance Interventions – increasing physical activity in girls in India Culturally, girls in India are not encouraged to take exercise CIH provides bicycles for school girls and organises cycling lessons

The Oxford Health Alliance Challenges ahead Data collection is due to be completed by the end of 2011 Analysis of the data will involve: –organisation and collation –support for the statistical team – one year’s duration (2012) to allow reports from each country individually and then to combine data to give overview results and messages –papers to be prepared for publication
