Question

1. What is the difference between mortality and morbidity? Provide two examples for each measured discussed in the text. 2. Define life erpectancy and explain how this indicator does not reflect. the age at which most people die in a country.

Answer 1

Mortality

The mortality is the state or condition of being a person or thing that is alive and therefore certain to die. mortality generally year by year and often increases greatly after a serious accident or illness.still, many people refuse to change behaviour that would improve their chances of living into old age. Mortality rates are calculated by government agencies, insurance companies and medical researchers.

Example:

1. The infant mortality rate is high -135 children die per every1,000 born, according to South Sudan Medical Journal.
2. The maternal mortality rate in 2010 was 18.8 deaths per 100,000 live births.

Morbidity

Morbidity is a term used to describe how often a disease occurs in a specific area or is a term used to describe a focus on death or departure from a state of physical or psychological well0being, resulting from disease, illness, injury or sickness..

example:

1. chronic disease such as rheumotoid arthritis are generally non-fatal, but can lead to high morbidity to patients.
2. Number of ovarian cancer cases diagnosed in many countries and they still alive.

Life expectancy

Life expectancy is the probable number of years remaining in the life of an individual or class of person determined statistically, affected by such factors such as heredity, physical condition nutrition and occupation.

Life expectancy in humans is the average number of life remaining for people of given age, assuming that everyone will experience, for the remainder of their lives, the risk of death based on a current life table.

For newborns today, life expectancy is about 77 years. Rapid declines in infant, child, maternal and late-life mortality during the 20th century led to an unprecedented 30-year increase in human life expectancy at birth from the 47 years that it was in developed countries in 1900.

To exceed this limit, the underlying processes of aging that increase vulnerability to all the common causes of death will have to be modified.
