Introduction Life expectancy is used as a development indicator for measuring developing of any country. Developed countries of the world have achieved considerable increase in life expectancy due to advancement in medical science. However, developing countries are still struggling hard to achieve the same level. The cause-specific death rates can demonstrate most prevalent diseases in the country. An age and cause specific death rate would give a more refined result of the same.
Methods Life table technique helps in examining the effect of elimination of a specific cause of death in life expectancy. One gets an idea about gain in life expectancy if one is able to control a specific disease. Diseases of circulatory system have become a major cause of death in developing countries including India. Therefore, present paper aims to construct such a life table using Medical Certification of Cause of Death data of Sample Registration System (SRS) in four selected states of India namely, Bihar, Rajasthan, Maharastra and Tamil Nadu to find out potential gain in average years of life due to prevention of mortality related circulatory system diseases.
Results The net gain in life expectancy at birth is found to be higher among females than males in all the states. Life tables are adjusted for the impact of differential risks of dying from other causes.
Conclusion This technique is useful in finding out potential benefits of cause elimination in health services and is essential for health policymakers and planners to set-up priorities in intervention programmes.
