Brief Summary:
To examine the impact of health determinants at the individual (e.g. health related behaviors) and societal level (e.g. environmental factors, health related policy, quality of health systems) on health outcomes (e.g. death, non-communicable disease development) across a range of socioeconomic and health resource settings. Additional components of this study will examine genetic factors for non-communicable diseases. This will be examined both through a cross sectional component, and prospectively (cohort component).

Condition or disease
Cardiovascular Diseases Risk Factor, Cardiovascular Health Behavior Environmental Exposure Lung Diseases Cancer Injuries Renal Disease Communicable Disease

Detailed Description:
  1. To examine the relationship between societal influences and prevalence of risk factors and chronic noncommunicable diseases. Societal determinants are measured by an index of measures from each of the 4 domains of interest: built environment, food and nutrition policy, psychosocial/socioeconomic factors, and tobacco.
  2. To examine the relationship between societal determinants and incidence of chronic noncommunicable disease events (e.g. cardiovascular disease, cancer) and on changes in rates of selected risk factors (e.g. smoking)
  3. To examine the relationship between health related behaviors (e.g. diet, physical activity, smoking, alcohol) and health outcomes (e.g. death, non-communicable diseases)
  4. The quality of health systems across a diverse range of health resource settings, and how this impacts health outcomes
  5. Genetic factors for non-communicable diseases

Plan to Share IPD: Yes
Plan Description: During study conduct only with the investigators who have participated /contributed to the study. Select summary data may be shared with policy makers for specific purposes.The study exec will consider specific requests for data analyses by non-contributing individuals 3 years after the study has been completed (i.e. complete recruitment and a minimum of 10 years follow up in all) and the participating investigators have had an opportunity to explore questions that they are interested in. Costs related to data curating ,and related efforts will need to be met by anybody not contributing to the study and requesting analyses
