According to the latest study in 2020, the average life expectancy at birth in Saudi Arabia was 75.28 years which is growing at an average rate of 0.69% annually. Along with this researchers have found that due to various reasons including smoking, hypertension, diabetes, and obesity the average life expectancy is reduced. It is estimated that on average 4.9 years in men and 4.1 years in women age is reduced due to various reasons.
To understand the reasons behind the reduction of life expectancy, first of all, we have to gain certain information regarding life expectancy.
Life expectancy involves the analysis of the average time an organism is expected to live depending on their birth year, their current age, and several other demographic factors including sex, genetics, or any other kind of illness.

Reasons of Reduction in Life Expectancy
Several reasons cause variations in life expectancy among different countries of the world and are mostly caused by
- Differences in public health

Along with this some of the important reasons for the reduction of average life expectancy and early deaths in children and young adults of developing countries are: Read more: Is Keto Diet Good for Your Health in Saudi Arabia?
