The Influence of Reproductive History on Post-Reproductive Mortality: A Case Study of Amish Women

The reproductive choices women make affect their health outcomes; however, the relevance of reproductive history on post-reproductive mortality varies according to the population under study. We examine whether the number of children a woman gives birth to, short birth intervals, late childbearing, having twins, and having children who die young have an influence on maternal mortality among the Amish. We use information from Amish directories to examine reproductive patterns of 228 women in this high fertility group. Our results indicate the patterns typically found for maternal mortality in the general population do not hold in our sample of Amish women. We suggest the mediating role of family and community is integral to understanding the maternal health patterns within the Amish community.

Breast cancer associated with pregnancy

Introduction. The problem of breast cancer associated with pregnancy for a long time attracts close attention. The incidence is relatively increasing, thanks in part to improved detection methods, but also to the growing trend towards late childbearing.Material and methods. The features of breast cancer treatment during pregnancy were studied, and the effect of pregnancy on the long-term prognosis and clinical course of breast cancer was evaluated.Results. All patients received treatment according to the clinical recommendations. Chemotherapeutic treatment was performed in 44 (77%) patients, surgical treatment in 54 (96%) cases, radiation therapy in 40(72%) patients, and hormone therapy in 24 (42%) women. Among the newborns, there were no significant malformations, one child (a girl) had an underdevelopment of the left lung tissue, and laterphysical development in accordance with age.Conclusion. The decision on the special treatment of breast cancer associated with pregnancy is made individually, the treatment has been planned together with obstetricians and gynecologists. Surgical and chemotherapeutic treatment (starting at 13 weeks) can be performed during pregnancy. Radiation therapy, hormone therapy, and targeted therapy should be postponed until delivery. Most patients have common forms of the disease and aggressive biological types of tumors. Currently, the features of the course of the disease, the prognosis, and the features of treatment in this category of patients are being studied.

Factor Modeling Of Russian Women’s Perceptions Of Combining Family And Career

Sociologists and demographers explain late childbearing by the transformation of the life values of modern women. This is considered as one of the reasons for the decline in the birth rate. Our study aims to reveal perceptions of the relationship between career and family in the life strategies of working Russian women by using factor analysis. We collected data in a sociological survey of working women living in the Ural region. We asked respondents to rate 10 statements about work, family and children. We constructed 3-factors model of Russian women’s perceptions of combining family and career. Then we used correlationanalysis to assess the relationship between these factors and the social and demographic parameters of the respondents. We concluded that the use of factor analysis made it possible to model a wide range of Russian women’s perceptions of combining family and career. Considering the results obtained may contribute to improving the regulation of interaction of two important societal spheres of professional and parental activities and create conditions for increasing the birth rate in Russia.

The realization of fertility intentions in the context of childbearing postponement: comparison of transitional and post-transitional populations

Childbearing postponement is a key demographic change that has been experienced by most European countries. It leads to a late-fertility pattern, with women realizing their reproductive plans preferentially after the age of 30. This may result in a lower fertility level. Since the ideal family size has not changed in most European countries, it has been argued that the end of the postponement transition further depends on the extent to which the lower fertility of younger women is compensated for by an increase in that of older women. Thus, the completion of the transition depends not only on the formation of a late childbearing pattern, but also on the capability of women to realize their reproductive plans if they commence childbearing later in their lives. This study employed a new approach to assess postponement transition based on analysis of the realization of the fertility intentions of women at later childbearing ages using survey panel data. A method that enables the differentiation between transitional and post-transitional cohorts was applied. The investigation was based on a comparison of the postponement transition in Czechia and France, the former being a post-communist and the latter a Western European country. It was found that despite having a similar pattern of fertility timing, Czechia and France underwent differing phases of postponement transition. The Czech population was identified as being transitional since only the ‘transition’ cohorts had completed their fertility during the period under study. These cohorts did not show a significant increase in realization of fertility intentions in later age. In contrast, the post-transitional French population is characterized by higher completed cohort fertility rates amongst women who entered motherhood at the age of 30 and over and by the significantly higher realization of fertility intentions for women aged 30–34 years.

Predicting Breast Cancer using Modern Data Science Methodology

Breast Cancer is the mass occurring cancer in women according to the World Health Organization(WHO), But the early prediction of breast cancer helps in the recovery for the effected one's. Reasons for breast cancer were Hormone replacement therapy or getting explore to harmful radioactive rays and due to late childbearing. The aim is to diagnose cancer by using a machine learning technique, Random Forest, for accurate solutions. The dataset we used is the Wisconsin Breast Cancer dataset. The output which the error rate was only about "0.0177"

POST-TRANSITIONAL FERTILITY: THE ROLE OF CHILDBEARING POSTPONEMENT IN FUELLING THE SHIFT TO LOW AND UNSTABLE FERTILITY LEVELS

SummaryThis study discusses fertility trends and variation in countries that completed the transition from high to around-replacement fertility in the 1950s to 1980s, especially in Europe, East Asia and North America, and summarizes the key relevant findings for those countries with a more recent experience of fertility decline towards replacement level. A central finding is that there is no obvious theoretical or empirical threshold around which period fertility tends to stabilize. Period fertility rates usually continue falling once the threshold of replacement fertility is crossed, often to very low levels. While cohort fertility rates frequently stabilize or change gradually, period fertility typically remains unstable. This instability also includes marked upturns and reversals in Total Fertility Rates (TFRs), as experienced in many countries in Europe in the early 2000s. The long-lasting trend towards delayed parenthood is central for understanding diverse, low and unstable post-transitional fertility patterns. In many countries in Europe this shift to a late childbearing pattern has negatively affected the TFR for more than four decades. Many emerging post-transitional countries and regions are likely to experience a similar shift over the next two to three decades, with a depression of their TFRs to very low levels.

Age model of fertility in Vojvodina at the beginning of the 21st century

This paper presents an outlook on fertility trends of the population of Vojvodina in the first decade of the 21st century, a period that includes the results of the previous two Censuses held in 2002 and 2011. The main concern is identifying determinants of this development process and the dynamics regarding the age model of fertility as well as the way it is manifested in Vojvodina. Methodology of this research relies on evaluating age specific rates, determining its fluctuations and shifts in order to establish the course of the change. Census of 2002 and Census of 2011 provide useful data to complete fertility analyses. Total fertility rates also show the tendency of continuous decline therefore representing the shifts in the age model of fertility. After the devastating 1990s marked by wars and sanctions, the transitional processes were initiated at the turn of the millennium, leading to a change in socio-economic environment. Along with constant economic crisis and accompanying poverty, this situation strongly influenced reproductive behaviour of women and their attitude toward childbearing in general. The trend of late childbearing and a raise of women?s mean age at first birth continued.

IDEAL VERSUS ACTUAL: THE CONTRADICTION IN NUMBER OF CHILDREN BORN TO NIGERIAN WOMEN

SummaryAlthough desired family size is often different from actual family size, the dynamics of this difference are not well understood. This paper examines the patterns and determinants of the difference between desired and actual number of children (unmet fertility desires) among women aged 15–49 years using pooled data from the 1990, 1999 and 2003 Nigeria Demographic and Health Surveys (NDHSs). The results show that more than two-thirds of the sample have unmet fertility desires (18.1% have more while 52.4% have fewer than desired). It was found that early and late childbearing increased the odds of unmet fertility desires. Also, women with low levels of education, from poor households, rural residents as well as those who had experienced child death were at a higher risk of unmet fertility desires in the multivariate context. The study highlights the policy and programme implications of the findings.
