Ten annual cohorts of men suffering from their first myocardial infarction have been followed up to a maximum period of 10.5 years. One thousand and twenty-three male patients of 1306 were smokers. Three months after the infarction 55% had stopped smoking and 45% continued smoking. These two groups were then compared and followed with regard to non-fatal reinfarctions and deaths. Preinfarction ...

This paper demonstrates the consequences of changes in mortality and health transition rates for changes in both health status life expectancy and the prevalence of health problems in the older population. A five-state multistate life table for the mid-1980s provides the baseline for estimating the effect of differing mortality and morbidity schedules. Results show that improving mortality alon...

The aim of the present study was to estimate disability-free life expectancy for the Brazilian elderly in 2003, by gender and age, based on different concepts of functional disability. The Sullivan method is used to combine the period life tables from the Brazilian Institute of Geography and Statistics (IBGE, 2003) and the prevalence of functional disability according to the 2003 National Sampl...

INTRODUCTION Physician shortages in the USA, an issue that has been particularly challenging in Mississippi, have been a concern among health scholars and policy makers for several decades. Physician shortages hinder residents from easily obtaining routine care, potentially magnifying health disparities. This study examines physician career life expectancy, or how long physicians typically prac...

Knowledge of bed bug development under varying conditions can lead to more sophisticated management techniques. Development rate, age and stage-specific life tables were compared for a laboratory strain (HS) and field strain (ECL-05) of bed bug Cimex lectularius L. (Hemiptera: Heteroptera) reared on two blood regimens: human or rabbit blood. Harlan and ECL-05 bed bugs reared on human blood had ...

For member states without a vital registration system as is Malawi, WHO uses other sources of adult mortality such as survey and census data to estimate the level of adult mortality. For under-five mortality, again, all available survey and census data are assessed, adjusted and averaged to estimate the probable trend in child mortality over the past few decades. For Malawi WHO used data from C...

This article proposes and illustrates a new lower bound on the economic benefits of reducing the number of deaths due to a particular cause and specifies the underlying economic and demographic assumptions. Unlike previous estimates of the increase in a population's output due to the extension of working lives, this new bound includes the present value to the existing population of avoiding fut...

The main goal of ecologists is nowadays to foster habitat and species conservation. Life-history tables and Leslie-Lewis transition matrices of population growth can be powerful tools suitable for the study of age-structured over harvested and/or endangered species dynamics. Red coral (Corallium rubrum L 1758) is a modular anthozoan endemic to the Mediterranean Sea. This slow growing, long live...

In an earlier paper, the development of 2 simulation models designed to describe the interaction between key elements of the rice agroecosystem and the population dynamics of Psorophora columbiae were presented (Focks et al. 1988a). The objective of the work reported herein was to validate these models with field data. The first model (WaterMod) predicts soil hydrology conditions as a function ...

Maternity histories from residents of a Pacific Island society, Tokelau, and migrants to New Zealand, are analysed using life table techniques. Inter-cohort differentials in patterns of family formation were found in the total Tokelau-origin population. The process of accelerated timing and spacing of pregnancies was more pronounced among migrants who tended to marry later, be pregnant at marri...
