China Rural Health Initiative Follow up Study

China Rural Health Initiative (CRHI), a large-scale, factorial, cluster-randomized, controlled trial was conducted in 120 villages selected from 5 Northern Provinces of rural China between 2010 and 2012. Two interventions were evaluated through CRHI. One is the standard disease management program of individuals at high risk of cardiovascular disease delivered by Primary Care Providers (village doctors). Another one is a community-based Salt Reduction program delivered by community health educators. CRHI study interventions had ended for two years now and provide a good opportunity for us to understand whether its effects could be prolonged to a longer term. This study wants to evaluate the effects of CRHI interventions at 2 years after the end of CRHI (from Sep 2014 to Feb 2015). In this follow-up survey, the baseline cohort of 5050 and post-intervention cohort of 4887 CRHI participants who were randomly selected from the 120 villages from 5 northern provinces of rural China will be recruited for the follow up study from Sep 2014 to Feb 2015. A questionnaire derived from CRHI baseline and post-intervention surveys will be used to collect data on disease history, medication use, care seeking patterns, lifestyle factors and so on. Weight, height, blood pressure and heart rate will be measured in the standard ways.
