Losses of expected lifetime in the United States and other developed countries: methods and empirical analyses.
(Demography, 2011-02) Shkolnikov, Vladimir M; Andreev, Evgeny M; Zhang, Zhen; Oeppen, James; Vaupel, James W
Patterns of diversity in age at death are examined using e (†), a dispersion measure that equals the average expected lifetime lost at death. We apply two methods for decomposing differences in e (†). The first method estimates the contributions of average levels of mortality and mortality age structures. The second (and newly developed) method returns components produced by differences between age- and cause-specific mortality rates. The United States is close to England and Wales in mean life expectancy but has higher life expectancy losses and lacks mortality compression. The difference is determined by mortality age structures, whereas the role of mortality levels is minor. This is related to excess mortality at ages under 65 from various causes in the United States. Regression on 17 country-series suggests that e (†) correlates with income inequality across countries but not across time. This result can be attributed to dissimilarity between the age- and cause-of-death structures of temporal mortality reduction and intercountry mortality variation. It also suggests that factors affecting overall mortality decrease differ from those responsible for excess lifetime losses in the United States compared with other countries. The latter can be related to weaknesses of health system and other factors resulting in premature death from heart diseases, amenable causes, accidents and violence.

Prevalence, components, and correlates of metabolic syndrome (MetS) among elderly Muscovites.
(Arch Gerontol Geriatr, 2012-09) Metelskaya, Victoria A; Shkolnikova, Maria A; Shalnova, Svetlana A; Andreev, Evgeny M; Deev, Alexander D; Jdanov, Dmitri A; Shkolnikov, Vladimir M; Vaupel, James W
The goal of this study is to estimate the prevalence of MetS, together with its components and correlates, among elderly Russians. Our population-based sample included randomly selected residents of Moscow aged 55 and older: 955 women with an average age of 67.6, and 833 men with an average age of 68.9. MetS was defined according to National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII). The prevalence of MetS was found to be 41.7% in women and 26.8% in men. It tended to decrease with age in men, but not in women. MetS was inversely related to education in women, but not in men. The most prevalent individual components of MetS were as follows: hypertension (64.4%), abdominal obesity (55%), and decreased high density lipoprotein cholesterol (HDL C) (46%) for women; and hypertension (71%) and fasting hyperglycemia (35.2%) for men. An elevated level of triglycerides (TG) was the rarest MetS component, affecting 23.5% of women and 22.1% of men. The higher female prevalence of MetS was attributable to abdominal obesity. MetS was found to be associated with markers of insulin resistance (IR), low-grade inflammation, and insufficient fibrinolysis. Although the metabolic burden is an important contributor to high levels of ill-health and cardiovascular mortality among elderly Russians (especially women), it does not explain why cardiovascular mortality is much higher in Russia than in other industrialized countries.

Steep increase in best-practice cohort life expectancy.
(Popul Dev Rev, 2011) Shkolnikov, Vladimir M; Jdanov, Dmitri A; Andreev, Evgeny M; Vaupel, James W
We analyze trends in best-practice life expectancy among female cohorts born from 1870 to 1950. Cohorts experience declining rather than constant death rates, and cohort life expectancy usually exceeds period life expectancy. Unobserved mortality rates in non-extinct cohorts are estimated using the Lee-Carter model for mortality in 1960–2008. Best-practice cohort and period life expectancies increased nearly linearly. Across cohorts born from 1870 to 1920 the annual increase in cohort length of life was 0.43 years. Across calendar years from 1870 to 2008, the annual increase was 0.28 years. Cohort life expectancy increased from 53.7 years in the 1870 cohort to 83.8 years in the 1950 cohort. The corresponding cohort/period longevity gap increased from 1.2 to 10.3 years. Among younger cohorts, survival to advanced ages is substantially higher than could have been anticipated by period mortality regimes when these cohorts were young or middle-aged. A large proportion of the additional expected years of life are being lived at ages 65 and older. This substantially changes the balance between the stages of the life cycle.
