  • United States Life Tables, 2018.
    National vital statistics reports : from the Centers for Disease Control and Prevention National Center for Health Statistics National Vital Statistic, 2020
    Co-Authors: Elizabeth Arias
    Abstract:

    Objectives-This report presents complete period Life Tables for the United States by Hispanic origin, race, and sex, based on age-specific death rates in 2018. Methods-Data used to prepare the 2018 Life Tables are 2018 final mortality statistics; July 1, 2018 population estimates based on the 2010 decennial census; and 2018 Medicare data for persons aged 66-99. The methodology used to estimate the Life Tables for the Hispanic population remains unchanged from that developed for the publication of Life Tables by Hispanic origin for data year 2006. The methodology used to estimate the 2018 Life Tables for all other groups was first implemented with data year 2008. In 2018, all 50 states and the District of Columbia reported deaths by race based on the 1997 Office of Management and Budget revised standards for the classification of federal data on race and ethnicity. As a result, race-specific Life Tables for 2018 presented in this report are based on the new standard and show estimates for single-race groups. These estimates are not completely comparable with those of previous years, which are based on bridged-race groups. To show trends and document the impact of changing to the 1997 standards, Life expectancy estimates for 2006-2018 are reported for bridged-race categories that were in use starting with data year 2000. Results-In 2018, the overall expectation of Life at birth was 78.7 years, increasing from 78.6 in 2017. Between 2017 and 2018, Life expectancy at birth increased by 0.1 year for males (76.1 to 76.2) and females (81.1 to 81.2). In 2018, Life expectancy at birth was 81.8 for the Hispanic population, 78.6 for the non-Hispanic single-race white population, and 74.7 for the non-Hispanic single-race black population.

  • U.S. decennial Life Tables for 1999-2001: state Life Tables.
    National vital statistics reports : from the Centers for Disease Control and Prevention National Center for Health Statistics National Vital Statistic, 2012
    Co-Authors: Rong Wei, Robert N. Anderson, Lester R. Curtin, Elizabeth Arias
    Abstract:

    OBJECTIVE This report, following publication of the national Life Tables (1,2) for 1999-2001, presents state-specific Life Tables for the 50 states and District of Columbia by race (white and black) and sex. These Tables are the most recent in a series of decennial Life Tables for the United States. METHODS Data used to prepare these state-specific Life Tables include population counts by age on the census date of April 1, 2000; deaths occurring in the 3-year period of 1999-2001; and counts of U.S. resident births during 1997-2001. Methods for calculating the Life Tables were modified from the previous decennial Life Tables to automate the smoothing of age-specific mortality data and to allow for the estimation of Life Tables for smaller population subgroups, which often had insufficient data available to estimate reliable Life Tables under the previous method. The current method allows for the estimation of Life Tables for the black population in six states, which were never previously published due to small numbers of deaths. Standard errors for estimating Life expectancy and probability of dying are also presented in this report. RESULTS Among the 50 states, Hawaii had the highest Life expectancy at birth during the 1999-2001 period at 80.23 years, and Mississippi had the lowest Life expectancy at 73.88 years. Life expectancy for the District of Columbia was even lower at 73.09 years. State-specific Life expectancy at birth improved from the previous decennial period (1989-1991) for all states and the District of Columbia. Life expectancy at age 65 ranged from 20.42 years in Hawaii to 16.61 years in Kentucky. Life expectancy at age 65 also improved for all states except Kentucky.

    Abstract:

    OBJECTIVES This report presents period Life Tables for the United States based on age-specific death rates for the period 1999-2001. These Tables are the most recent in a 100-year series of decennial Life Tables for the United States. METHODS This report presents complete Life Tables by age, race (white and black), and sex. Also presented are standard errors of the probability of dying and Life expectancy. The data used to prepare these Life Tables are population estimates based on the 2000 decennial census, deaths occurring in the United States to U.S. residents in the 3 years 1999-2001, counts of U.S. resident births in the years 1997-2001, and population and death counts from the Medicare program for years 1999-2001. RESULTS In 1999-2001, Life expectancy at birth was 76.83 years for the total U.S. population, representing an increase of 27.59 years from a Life expectancy of 49.24 years in 1900. Between 1900 and 2000, Life expectancy increased by 40.08 years for black females (from 35.04 to 75.12), by 35.54 years for black males (from 32.54 to 68.08), by 28.89 years for white females (from 51.08 to 79.97), and by 26.51 years for white males (from 48.23 to 74.74).

Presented are complete Life Tables by age, race, and sex. In 1998 the overall expectation of Life at birth was 76.7 years, an increase of 0.2 years compared with Life expectancy in 1997. Life expectancy increased from 1997 to 1998 for each of the four race-sex groups for which Life expectancy is reported. Life expectancy increased for black males by 0.4 year (from 67.2 to 67.6), for black females by 0.1 year (from 74.7 to 74.8), for white males by 0.2 year (from 74.3 to 74.5), and for white females by 0.1 year (from 79.9 to 80.0).

  • United States Life Tables, 1997.
    National vital statistics reports : from the Centers for Disease Control and Prevention National Center for Health Statistics National Vital Statistic, 1999
    Co-Authors: Robert N. Anderson
    Abstract:

    The Life Tables in this report are current Life Tables for the United States based on age-specific death rates in 1997. Beginning with 1997 mortality data, complete U.S. Life Tables were constructed using a new methodology that replaces the abridged Life table methodology used previously. The methodology is similar to that used in the decennial Life Tables. Also, Life expectancy and other Life table values are shown for ages 85 to 100 years for the first time as part of the annual U.S. Life Tables. Data used to prepare these Life Tables are 1997 final mortality statistics; July 1, 1997, population estimates; and data from the Medicare program. Presented are complete Life Tables by age, race, and sex. In 1997 the overall expectation of Life at birth was 76.5 years, an increase of 0.4 years compared with Life expectancy in 1996. Life expectancy increased from 1996 to 1997 for each of the four race-sex groups for which Life expectancy is reported. Life expectancy increased for black males by 1.1 year (from 66.1 to 67.2), for black females by 0.5 year (from 74.2 to 74.7), for white males by 0.4 year (from 73.9 to 74.3), and for white females by 0.2 year (from 79.7 to 79.9).

  • On models for the estimation of the excess mortality hazard in case of insufficiently stratified Life Tables
    Biostatistics, 2019
    Co-Authors: Francisco Rubio, Bernard Rachet, Camille Maringe, Roch Giorgi, Aurélien Belot
    Abstract:

    In cancer epidemiology using population-based data, regression models for the excess mortality hazard is a useful method to estimate cancer survival and to describe the association between prognosis factors and excess mortality. This method requires expected mortality rates from general population Life Tables: each cancer patient is assigned an expected (background) mortality rate obtained from the Life Tables, typically at least according to their age and sex, from the population they belong to. However, those Life Tables may be insufficiently stratified, as some characteristics such as deprivation, ethnicity, and comorbidities, are not available in the Life Tables for a number of countries. This may affect the background mortality rate allocated to each patient, and it has been shown that not including relevant information for assigning an expected mortality rate to each patient induces a bias in the estimation of the regression parameters of the excess hazard model. We propose two parametric corrections in excess hazard regression models, including a single-parameter or a random effect (frailty), to account for possible mismatches in the Life table and thus misspecification of the background mortality rate. In an extensive simulation study, the good statistical performance of the proposed approach is demonstrated, and we illustrate their use on real population-based data of lung cancer patients. We present conditions and limitations of these methods and provide some recommendations for their use in practice.

  • deprivation specific Life Tables using multivariable flexible modelling trends from 2000 2002 to 2010 2012 portugal
    BMC Public Health, 2019
    Co-Authors: Luis Antunes, Camille Maringe, Denisa Mendonca, Ana Isabel Ribeiro, Bernard Rachet
    Abstract:

    Completing mortality data by information on possible socioeconomic inequalities in mortality is crucial for policy planning. The aim of this study was to build deprivation-specific Life Tables using the Portuguese version of the European Deprivation Index (EDI) as a measure of area-level socioeconomic deprivation, and to evaluate mortality trends between the periods 2000–2002 and 2010–2012. Statistics Portugal provided the counts of deaths and population by sex, age group, calendar year and area of residence (parish). A socioeconomic deprivation level was assigned to each parish according to the quintile of their national EDI distribution. Death counts were modelled within the generalised linear model framework as a function of age, deprivation level and calendar period. Mortality Rate Ratios (MRR) were estimated to evaluate variations in mortality between deprivation groups and periods. Life expectancy at birth increased from 74.0 and 80.9 years in 2000–2002, for men and women, respectively, and to 77.6 and 83.8 years in 2010–2012. Yet, Life expectancy at birth differed by deprivation, with, compared to least deprived population, a deficit of about 2 (men) and 1 (women) years among most deprived in the whole study period. The higher mortality experienced by most deprived groups at birth (in 2010–2012, mortality rate ratios of 1.74 and 1.29 in men and women, respectively) progressively disappeared with increasing age. Persistent differences in mortality and Life expectancy were observed according to ecological socioeconomic deprivation. These differences were larger among men and mostly marked at birth for both sexes.

  • A novel ecological methodology for constructing ethnic-majority Life Tables in the absence of individual ethnicity information
    Journal of epidemiology and community health, 2015
    Co-Authors: Melanie Morris, Laura M. Woods, Bernard Rachet
    Abstract:

    Background Deprivation-specific Life Tables have been in use for some time, but health outcomes are also known to vary by ethnicity over and above deprivation. The mortality experiences of ethnic groups are little studied in the UK, however, because ethnicity is not captured on death certificates. Methods Population data for all Output Areas (OAs) in England and Wales were stratified by age-group, sex and ethnic proportion, and matched to the deaths counts in that OA from 2000 to 2002. We modelled the relationship between mortality, age, deprivation and ethnic proportion. We predicted mortality rates for an area that contained the maximum proportion of each ethnic group reported in any area in England and Wales, using a generalised linear model with a Poisson distribution adjusted for deprivation. Results After adjustment, Asian and White Life expectancies between 1 and 80 years were very similar. Black men and women had lower Life expectancies: men by 4 years and women by around 1.5 years. The Asian population had the lowest mortality of all groups over age 45 in women and over 50 in men, whereas the Black population had the highest rates throughout, except in girls under 15. Conclusions We adopted a novel ecological method of constructing ethnic-majority Life Tables, adjusted for deprivation. There is still diversity within these three broad ethnic groups, but our data show important residual differences in mortality for Black men and women. These ethnic Life Tables can be used to inform public health planning and correctly account for background mortality in ethnic subgroups of the population.

  • Life Tables for the concord 2 study
    2015
    Co-Authors: Devon Spika, Bernard Rachet, Laura M. Woods, Finian Bannon, Camille Maringe, Audrey Bonaventure, Michel P Coleman
    Abstract:

    The CONCORD-2 study has initiated worldwide surveillance of population-based cancer survival, a metric designed to assess the overall effectiveness of health systems in managing cancer, and to inform global policy on cancer control. Patient data were obtained from 279 population-based cancer registries in 67 countries. Centralised quality control and analysis was performed on individual tumour records for 25·7 million adults (age 15-99 years) and 75,000 children (age 0-14 years) diagnosed with one of 10 cancers during 1995-2009. Net survival up to five years from diagnosis was estimated as the survival probability after compensation for background mortality from other causes. The background mortality is contained in Life Tables. More than 12,000 Life Tables are provided, classified by Continent, Country, Registry (Region), Race/Ethnicity (selected populations), Calendar year and Sex. Each Life table contains the central all-cause mortality rate per 100,000 person-years, the probability of death, and the probability of survival by single year of age (0-99 years). Researchers must complete a CSG User Registration Form to gain access.

  • the impact of Life Tables adjusted for smoking on the socio economic difference in net survival for laryngeal and lung cancer
    British Journal of Cancer, 2014
    Co-Authors: Libby Ellis, Michel P Coleman, Bernard Rachet
    Abstract:

    Net survival is a key measure in cancer control, but estimates for cancers that are strongly associated with smoking may be biased. General population Life Tables represent background mortality in net survival, but may not adequately reflect the higher mortality experienced by smokers. Life Tables adjusted for smoking were developed, and their impact on net survival and inequalities in net survival for laryngeal and lung cancers was examined. The 5-year net survival estimated with smoking-adjusted Life Tables was consistently higher than the survival estimated with unadjusted Life Tables: 7% higher for laryngeal cancer and 1.5% higher for lung cancer. The impact of using smoking-adjusted Life Tables was more pronounced in affluent patients; the deprivation gap in 5-year net survival for laryngeal cancer widened by 3%, from 11% to 14%. Using smoking-adjusted Life Tables to estimate net survival has only a small impact on the deprivation gap in survival, even when inequalities are substantial. Adjusting for the higher, smoking-related background mortality did increase the estimates of net survival for all deprivation groups, and may be more important when measuring the public health impact of differences or changes in survival, such as avoidable deaths or crude probabilities of death.

  • differences in cancer survival with relative versus cause specific approaches an update using more accurate Life Tables
    Cancer Epidemiology Biomarkers & Prevention, 2019
    Co-Authors: Goncalo Forjaz De Lacerda, Nadia Howlader, Angela B. Mariotto
    Abstract:

    Background: We investigated differences in net cancer survival (survival observed if the only possible cause of death was the cancer under study) estimated using new approaches for relative survival (RS) and cause-specific survival (CSS). Methods: We used SEER data for patients diagnosed in 2000 to 2013, followed-up through December 31, 2014. For RS, we used new Life Tables accounting for geography and socio-economic status. For CSS, we used the SEER cause of death algorithm for attributing cancer-specific death. Estimates were compared by site, age, stage, race, and time since diagnosis. Results: Differences between 5-year RS and CSS were generally small. RS was always higher in screen-detectable cancers, for example, female breast (89.2% vs. 87.8%) and prostate (98.5% vs. 93.7%) cancers; differences increased with age or time since diagnosis. CSS was usually higher in the remaining cancer sites, particularly those related to specific risk factors, for example, cervix (70.9% vs. 68.3%) and liver (20.7% vs. 17.1%) cancers. For most cancer sites, the gap between estimates was smaller with more advanced stage. Conclusion: RS is the preferred approach to report cancer survival from registry data because cause of death may be inaccurate, particularly for older patients and long-term survivors as comorbidities increase challenges in determining cause of death. However, CSS proved to be more reliable in patients diagnosed with localized disease or cancers related to specific risk factors as general population Life Tables may not capture other causes of mortality. Impact: Different approaches for net survival estimation should be considered depending on cancer under study.

  • The impact of state-specific Life Tables on relative survival.
    Journal of the National Cancer Institute. Monographs, 2014
    Co-Authors: Antoinette M. Stroup, Hyunsoon Cho, Steve Scoppa, Hannah K. Weir, Angela B. Mariotto
    Abstract:

    There is little debate that measures of survival are a valuable tool available to clinicians, epidemiologists, and public health professionals (1). First proposed by Ederer et al. (2) relative survival compares the survival probabilities of a diseased population (ie, cancer patients) to the survival probabilities of the general population. The resulting value, known as relative survival, is the ratio of observed survival to expected survival which represents the excess mortality associated with a cancer diagnosis. Relative survival is often used as the primary measure in population-based descriptive studies as in general it provides a more reliable estimate of the net survival from cancer than cause-specific survival because it does not rely on death certificate information, which is generally prone to errors in the coding of cause of death and has been shown to have high degrees of misclassification for cancer causes of death (3–5). Unlike crude probabilities of death, net survival represents cancer survival in the absence of competing risks (6). In this issue, Howlader et al.(7) and Mariotto et al. (8) further discuss differences between net and crude survival measures. A key challenge of relative survival is in choosing the population with which to compare to the cancer cohort or in choosing the best Life Tables to represent the background mortality of the study population. There is a growing body of research questioning the accuracy of relative survival estimates that use Life Tables from populations that are either not comparable to the cancer cohort [eg, background mortality risk is substantially higher or lower than the cancer cohort, misclassification or unmeasured factors such as race/ethnicity that contribute to differential death rates in the comparison population (9–11)] or when the reference population has a high rate of deaths due to cancer (12). In the United States, researchers using cancer surveillance data from the Surveillance Epidemiology and End Results (SEER) Program often use the US population Life Tables as the reference group for relative survival estimates, matched by age, sex, race, and calendar year to the cancer cohort (13). The use of US population Life Tables in and of itself is not necessarily a problem if the cancer cohort has comparable background death rates and characteristics. However, we know that background mortality varies by sex, age, race, and geographic areas as well as socioeconomic status (SES) (14–16). The use of national Life Tables to calculate state-specific or regional survival has overestimated relative survival in states with lower background death rates and underestimated relative survival in states with higher background death rates (9). Baili et al. (9) reported that even after matching on age, sex, year, and race, relative survival for several US states and regional registry populations were systematically higher when using US-matched Life Tables compared to the relative survival estimates using SLT [aka: the CONCORD approach (9)]. The only exception was found in Louisiana, which had higher US-matched relative survival estimates as compared to its state-matched relative survival estimates. The authors attributed these differences to the lower background death rates in all states/regions in their study with the exception of Louisiana, which had higher background death rates. Moreover, for early stage prostate and breast cancer, relative survival has been shown to be higher than 100%, indicating that the Life Tables may not be appropriate for representing survival from other causes when examining cancer survival for these populations (9). With the recent release of the 2000 state decennial Life Tables by the National Center for Health Statistics (NCHS) (17), this study expands on the work by Baili et al. (9) by comparing five-year relative survival using state- or regionally-matched Life Tables to US-matched five-year relative survival, focusing on a more contemporary cohort of cancer patients diagnosed from 2000 to 2009. We also examine the underlying characteristics of each state/region to identify potential root causes of variations in survival estimates and assess the variations in survival estimates by age, race, and cancer site for lung and bronchus cancer, colorectal cancer, prostate cancer, and female breast cancer.

  • Life Tables adjusted for comorbidity more accurately estimate noncancer survival for recently diagnosed cancer patients
    Journal of Clinical Epidemiology, 2013
    Co-Authors: Angela B. Mariotto, Hyunsoon Cho, Zhuoqiao Wang, Carrie N Klabunde, Barnali Das, Eric J Feuer
    Abstract:

    Abstract Objectives To provide cancer patients and clinicians with more accurate estimates of a patient's Life expectancy with respect to noncancer mortality, we estimated comorbidity-adjusted Life Tables and health-adjusted age. Study Design and Setting Using data from the Surveillance Epidemiology and End Results–Medicare database, we estimated comorbidity scores that reflect the health status of people who are 66 years of age and older in the year before cancer diagnosis. Noncancer survival by comorbidity score was estimated for each age, race, and sex. Health-adjusted age was estimated by systematically comparing the noncancer survival models with US Life Tables. Results Comorbidity, cancer status, sex, and race are all important predictors of noncancer survival; however, their relative impact on noncancer survival decreases as age increases. Survival models by comorbidity better predicted noncancer survival than the US Life Tables. The health-adjusted age and national Life Tables can be consulted to provide an approximate estimate of a person's Life expectancy, for example, the health-adjusted age of a black man aged 75 years with no comorbidities is 67 years, giving him a Life expectancy of 13 years. Conclusion The health-adjusted age and the Life Tables adjusted by age, race, sex, and comorbidity can provide important information to facilitate decision making about treatment for cancer and other conditions.

    Abstract:

    The objective of this work was to establish, under experimental laboratory conditions, a colony of Lucilia sericata, Bogota-Colombia strain, to build Life Tables and evaluate two artifcial diets. This blowfy is frequently used in postmortem interval studies and in injury treatment. The parental adult insects collected in Bogota were maintained in cages at 22°C±1 average temperature, 60%±5 relative humidity and 12 h photoperiodicity. The blowfies were fed on two artifcial diets that were evaluated over seven continuous generations. Reproductive and population parameters were assessed. The Life cycle of the species was expressed in the number of days of the different stages: egg = 0.8±0.1, larvae I = 1.1±0.02, larvae II = 1.94±0.16, larvae III = 3.5±0.54, pupae = 6.55±0.47, male adult = 28.7±0.83 and female adult = 33.5±1.0. Total survival from egg stage to adult stage was 91.2% for diet 1, while for diet 2 this parameter was 40.5%. The Lifetime reproductive output was 184.51±11.2 eggs per female. The population parameters, as well as the reproductive output of the blowfies that were assessed, showed relatively high values, giving evidence of the continuous increase of the strain over the different generations and making possible its maintenance as a stable colony that has lasted for more than two years.
