The effect of inbreeding on early childhood mortality: Twelve generations of an amish settlement

An unresolved issue in research on child survival is the extent to which familial mortality risk in infancy is due to biological influences net of sociodemographic and economic factors. We examine the effect of consanguinity on early childhood mortality in an Old Order Amish settlement by using the inbreeding coefficient, an explicit measure of the degree of relatedness in one’s ancestry. Inbreeding has a net positive effect on neonatal and postneonatal deaths. We find social, demographic, and population-based sociocultural explanations for this effect among the Amish population, which is known to experience certain genetically transmitted defects associated with mortality.

Consanguineous marriage and early childhood mortality in an Amish settlement

Abstract This paper examines the effect of inbreeding as a direct measure of consanguinity on early childhood mortality. Data are from a church directory of the Old Order Amish of the Lancaster, PA, settlement. The sample includes all infant deaths and a probability sample of survivors (total N = 1,823). We find that inbreeding has a net positive effect on neonatal and infant deaths and on the instantaneous hazard rate. However, we also find socioeconomic and other explanations, even in this population, likely to experience certain genetically transmitted defects associated with infant mortality.

HEALTH OF THE ELDERLY POPULATION IN RACIALLY DIVERSE CITIES AND COUNTIES OF XINJIANG, CHINA

This research examines the impact of ethnic concentration and community socioeconomic status (SES) on elderly health in ethnically diverse communities in Xinjiang in northwest China. Effects of the concentration of two major ethnic populations are compared: the Han, which is the dominant ethnic group in China, and the Uyghur, the largest Muslim group in Xinjiang. Net of socioeconomic status, we find that population densities of the ethnic groups have a significant impact on our aggregate-level indicators of elderly health. Han density predicts good health, while Uyghur density predicts poor health. However, we do not find that SES indicators are independent predictors of community elder health. These findings suggest that rapidly developing economies, like those in China, do not necessarily provide the attention to health care that would result in improved quality of life and health status for the population.

Fertility decline in a US population favoring large families: A hazard-model analysis of the effect of sib death on Amish fertility

This paper uses proportional hazards techniques and population data from a directory of the Old Order Amish of the Lancaster, PA settlement. It examines the effect of death of the immediately prior sibling on the risk of childbearing for up to 11 children. Prior research typically has pooled data for maternal cohorts. In contrast, separate models are estimated for each maternal cohort. The results are based on all reported first marriages of Amish women born between 1884–1973 (N = 4066). Hazard models run separately for children of each birth order reveal that net of maternal age and length of the prior birth interval (and other statistical and design controls), the death of the prior sib significantly increases the risk of a subsequent birth for the lower birth orders. Separate models by maternal cohort show that sib death increases the risk primarily for later cohorts. The pattern of effects from child mortality and other variables suggests changes in fertility behavior among the Amish, who have strong, traditional norms opposing contraception and favoring large families.

Teaching Strategies and Young Women's Organizational Skills on the Job

Abstract This paper examines the extent to which teaching strategies provide socialization experiences to young women that foster the skills needed to promote their early careers. The study is guided by literature on formal social relations in schools and workplaces. Data from three methods are examined: classroom observations of female students preparing for work, personal interviews with the students and discussions with their teachers, and a mail survey of their employers. Noncollege women who can demonstrate to employers that they can successfully manage workplace rules and regulations are more likely to be rated as successful at work and obtain available promotions than are their peers without these skills. However, the work organizations they enter provide little formal access to power, and teachers do not socialize all female students for work in ways that will help them be successful in situations involving employers and clients. Further research clearly is needed on how success in work settings i...

How do maternal characteristics influence infant survival

Abstract Considerable progress has been made during the last decade in identifying the critical social and demographic factors, such as education, health care and socioeconomic status, that influence infant and child mortality. However, much less attention has been paid to the mechanisms by which these factors operate. This research examines the direct and indirect effects of social and demographic background measures on infant deaths to determine by what paths these factors operate. It also uses a design that controls for the multiplicity of factors often confounding research results. Data are from a church directory of the Old Order Amish of the Lancaster, PA, Settlement, which includes virtually all members of the community. The Amish are a traditional agricultural religious group that maintains a high degree of isolation from the rest of the community. They are homogeneous in level of education and division of work by gender, and are similar in minimum age at marriage, childrearing practices, and trad...
