- Visit the website of the National Center for Health Statistics. Spend some time studying the leading causes of death for different age groups at www.cdc. gov/nchs/data/nvsr/nvsr56/nvsr56_05.pdf. What are the three leading causes of death for each age cohort listed? What are some of the policy implications?It is often stated that excess mortality (in general) is higher in low socioeconomic populations. Which factors contribute to this statistic?Please define and compare morbidity vs mortality? Provide 3 examples for each concept
- Identify what type of mortality indicator is depicted in the following graph.Define the following and give examples of each:Density independent limiting factor - Density dependent limiting factor -Which of the following mortality rates use the estimated total mid-year population as its denominator? [ O Sex-specific mortality rate O Crude mortality rate O Age-specific mortality rate Cause-specific proportionate mortality rate A new treatment is developed that prevents death but does not produce recovery from disease. Which of the following will occur? O Prevalence will decrease O Incidence will decrease O Incidence will increase Prevalence will increase
