They say: "The striking loss of DFLE
in diabetes reported in this study is likely to raise concern about the burden of diabetes in future decades, indicating a need to respond by implementing intervention and prevention of disability.
1--Absolute compression and relative compression of morbidity: a reduction in LE-D and increase in the percentage of DFLE in LE.
2--Absolute compression and relative expansion of morbidity: a reduction in LE-D and a reduction in the percentage of DFLE in LE.
3--Absolute expansion and relative compression of morbidity: an increase in LE-D and an increase in the percentage of DFLE in LE.
Average DFLE for panel/was calculated as the average number of life years free of disability over all age cohorts, weighted by the gender and race/ethnicity distribution in panel i.
Trends in DFLE reflect the complex interaction over time among trends in disability incidence, recovery, and mortality.
6 years in 2002, whereas average DFLE increased significantly by 1.
DFLE incorporates a dichotomous weighting in which '1' is ascribed to perfect health and '0' to the diseased and death statuses (36).
Total life expectancy, diabetes-free life expectancy (DFLE) and diabetes life expectancy (DLE) at 60 years of age, by sex, based on self-reported diabetes from the Survey on Health, Well-Being, and Aging in Latin America and the Caribbean, 2000 (SABE); and the Mexican Health and Aging Study, 2001 (MHAS) (weighted estimates) Total life expectancy Standard at age 60 DLE DFLE error of Sex and geographic area ([e.
Table 2 shows that the DFLE estimate at birth (age zero) for males are about four years less than that for females, which means that in comparison to women the overall effect of disabilities on the life span of men is more prolonged.
Since disability rates are inversely related to level development the DFLE (and the DFLE/LE ratios) for Pakistan should be logically higher than those for the developed countries.
It is my feeling here that the analysis done in the paper with respect to DFLE is rather premature.
