Mortality deceleration at older ages in Kerala
Dr. Laya KS
The rate of mortality increases almost exponentially with age through most of the adult age range in human populations. However, the rate of mortality increase with age tends to slow down at older ages and evidences of this deceleration encouraged the researchers to switch from the exponential to the logistic power function in which the rate of mortality increase slows down with advancing age. The present study is an attempt to examine whether there exist any evidence of deceleration in the age pattern of mortality at older ages in general and for males and females separately in the state of Kerala in India. An attempt has also been made to compare the phenomenon of mortality deceleration at older ages in Kerala with that in India. Death rates for the elderly by age and sex during 1997-2016, taken at five year intervals, from the SRS of India were analysed using Life Table Ageing Rate (LAR) technique.
The study shows clear evidence of mortality deceleration taking place at older ages in Kerala and is around the age of 75 years. Even though females in Kerala live longer compared to males, the pace of mortality increase with age at older ages is faster for females. That is, females are frailer than males at their older ages in Kerala. The study also found evidences of mortality deceleration taking place at older ages in India. The implications of mortality deceleration are many. The Government need to provide more support programmes for the elderly, especially for the elderly women. Focus should be placed on frailty, which underlies mortality, morbidity and disability at older ages.
