ANTC67H3 Lecture Notes - Lecture 1: Health Promotion, Statistical Hypothesis Testing, Prospective Cohort Study
Document Summary
Fertility rate: western world (long life and small family) vs. third world (small life big family) Access to health care: healthy countries advance faster than richer. Income: bigger the gdp per capita, the longer the child survives. Within countries there are diversity within data. Epidemiology transition: 1900 tuberculosis and pneumonia vs. 2010 cancer and chronic disease. Over time we shifted from infectious to chronic disease due to vaccination, increase life expectancy and changes in lifestyle. Lots of developing countries are still affected with infectious disease. Epidemiology: study of distribution and determinants of health-related states or events in specified population and the application of this study to the prevention and control of health problems. Study: research approach, surveillance (most often done in epidemiology), observational(looking at associations without specific hypothesis), hypothesis testing (theory and hypothesis), analytic studies and experiment. Health related outcome: diseases occurrence, death, health behavior, positive health state (quality of life), reaction to preventive medicine (side effects), health service utilization.
