Cause-specific contributions to sex differences in adult mortality among whites and African Americans between 1960 and 1995

The purpose of this paper is to describe trends in sex differences in mortality in young adulthood and in middle age among African Americans and whites in the United States between 1960 and 1995. We examine trends in all-cause mortality and estimate the contribution of leading causes of death to the change in the sex difference in mortality over time. Between 1960 and 1995 the sex difference in mortality increased for African Americans and whites at ages 15-39 and declined for whites but increased for African Americans at ages 40-64. Our results reveal considerable variation in the sex difference in mortality by cause of death as well as in the contribution various causes of death make to the change in the sex mortality difference over time.cause of death, mortality, USA

Chloride-depletion of photosynthetic water oxidase No proton release during the second oxidation step, S2∗ ⇒ S3∗, and a transmembrane radical pair recombination from the third on

AbstractChloride depletion blocks the normal four-step progress of photosynthetic water oxidation. We studied proton release in chloride-depleted thylakoids which were dark-adapted and excited by flashing light. Proton release was blocked from the second flash on, possibly leaving an uncompensated positive charge in the catalytic centre. The reduction of P+680 by Tyrz was still very rapid (⪡ 10 μs). From the third flash on, P+680 was reduced more slowly (70 μs200 μs), and by an electrogenic back-reaction. The uncompensated positive charge may be the reason why the rapid reduction of P+680 by Tyrz is prevented and the transmembrane charge-pair recombination is facilitated

Black-White Differentials in Cause-Specific Mortality in the United States during the 1980s: The Role of Medical Care and Health Behaviors

In this paper, we examine black-white differences in cause-specific mortality during the 1980s when black-white disparities in mortality widened in the United States. We group causes of death to those amenable to medical intervention, those closely linked to health behaviors or residential location, and all other causes combined. At older ages, we treat cardiovascular disease, stroke, and forms of cancer not amenable to medical or behavioral intervention as distinct causes. We conduct separate analyses by gender and age group. Causes of death amenable to medical intervention and those linked to health behaviors and residential location accounted for over 60% of the absolute black-white difference in male and female mortality at ages 25-44, male mortality at ages 45-74, but somewhat less than 50% of the black-white difference in female mortality at these older ages. The relative black excess risk was most pronounced for causes amenable to medical intervention with and without adjustment for socio-demographic characteristics

Childhood Conditions that Predict Survival to Advanced Ages Among African Americans

This paper investigates the social and economic circumstances of childhood that predict the probability of survival to age 85. It uses a unique study design in which survivors are linked to their records in U.S. Censuses of 1900 and 1910. A control group of age and race-matched children is drawn from Public Use Samples for these censuses. It concludes that the factors most predictive of survival are farm background, having literate parents, and living in a two-parent household. Results support the interpretation that death risks are positively correlated over the life cycle

Is the pen mightier than the sword? Exploring urban and rural health in Victorian England and Wales using the Registrar General Reports

YesIn AD 1836, the General Register Office (GRO) was established to oversee the national system of civil registration in England and Wales, recording all births, deaths and marriages. Additional data regarding population size, division size and patterns of occupation within each division permit urban and rural areas (and those with both urban and rural characteristics, described here as ‘mixed’) to be directly compared to each other. The annual Reports of the Registrar General summarize the collected data, including cause of and age at death, which is of particular value to historical demographers and bioarcheologists, allowing us to investigate demographic patterns in urban and rural districts in the nineteenth century. Overall, this paper aims to highlight how this documentary evidence can supplement osteological and paleopathological data to investigate how urbanization affected the health of past populations. It examines the data contained within the first Registrar General report (for 1837-8), in order to assess patterns of mortality of diverse rural, urban, and mixed populations within England and Wales at a point in time during a period of rapid urbanization. It shows that urban and mixed districts typically had lower life expectancy and different patterns in cause of death compared to rural areas. The paper briefly compares how the documentary data differs from information regarding health from skeletal populations, focusing on the city of London, highlighting that certain age groups (the very young and very old) are typically underrepresented in archeological assemblages and reminding us that, while the paleopathological record offers much in terms of chronic health, evidence of acute disease and importantly cause of death can rarely be ascertained from skeletal remains.This research was funded by the Royal Society of London (Grant Reference IES\R1\180138) and supported by the University of Bradford and SUNY Plattsburgh

Early life patterns of common infection: a latent class analysis

Early life infection has been implicated in the aetiology of many chronic diseases, most often through proxy measures. Data on ten infectious symptoms were collected by parental questionnaire when children were 6 months old as part of the Avon Longitudinal Study of Parents and Children, United Kingdom. A latent class analysis was used to identify patterns of infection and their relationship to five factors commonly used as proxies: sex, other children in the home, maternal smoking, breastfeeding and maternal education. A total of 10,032 singleton children were included in the analysis. Five classes were identified with differing infectious disease patterns and children were assigned to the class for which they had a highest probability of membership based on their infectious symptom profile: ‘general infection’ (n = 1,252, 12.5%), ‘gastrointestinal’ (n = 1,902, 19.0%), ‘mild respiratory’ (n = 3,560, 35.5%), ‘colds/ear ache’ (n = 462, 4.6%) and ‘healthy’ (n = 2,856, 28.5%). Females had a reduced risk of being in all infectious classes, other children in the home were associated with an increased risk of being in the ‘general infection’, ‘mild respiratory’ or ‘colds/ear ache’ class. Breastfeeding reduced the risk of being in the ‘general infection’ and ‘gastrointestinal’ classes whereas maternal smoking increased the risk of membership. Higher maternal education was associated with an increased risk of being in the ‘mild respiratory’ group. Other children in the home had the greatest association with infectious class membership. Latent class analysis provided a flexible method of investigating the relationship between multiple symptoms and demographic and lifestyle factors
