While in Spain and Italy cohabitation has not acquired the same role that it has had in Northern Europe, in both of these Mediterranean countries cohabitation is no longer a marginal phenomenon. Moreover, the nature of cohabiting couples is diverse. According to the most recent FFS data, first cohabitations constitute a temporary arrangement that usually ends in the formalization of the union (marriage), and within 5 years 28.9 % of first cohabitations in Spain and 51.7 % in Italy were transformed into marriages. Within a Western context of changes in union formation patterns, the study of the choice between marriage and cohabitation as first union is of great significance. Is it possible to identify a shared pattern of union formation in Mediterranean countries like Italy and Spain? The purpose of this paper is to examine the choice between cohabitation and marriage as first union (timing, incidence and determinants) using a comparative life course approach. For the analysis of the timing and prevalence, cumulative incidence curves are calculated by birth cohorts and regions; while two semiparametric competing-risks models are estimated for the determinants of first partnership formation (one for each country), considering birth cohort, parental separation, educational attainment, employment status, age at leaving the parental home and birth of a child (the last three time-varying) as independent variables.  相似文献

The dynamics of leaving home for youth from migrant families in the Netherlands are examined using individual administrative data on the 1977 and 1983 birth cohorts for the period 1999–2004. A competing-risks approach is applied to distinguish leaving home for union formation, to live independently, and to share with others. Migrant youth, and particularly Turkish and Moroccan youth, leave home at a significantly younger age than Dutch youth, given the relevant background variables. This is remarkable, given the older ages at which young people in the origin countries leave the parental home. The result may be seen as evidence of how the potential effects of cultural norms are counter-affected by other factors, such as the facilities of the welfare state and the awkward position of migrant youth between two cultures. Considering the pathways out of home, the analysis largely confirms the expected pattern: Turkish and Moroccan youth leave home more often for union formation and particularly marriage, while this pathway is of minor importance for Dutch youth at early ages.  相似文献

Trends and determinants of daughter-parent coresidence over the twentieth century are examined by using the 1987-1988 National Survey of Families and Households. Young women from more recent birth cohorts leave their parents’ homes for the first time at earlier ages, but are more likely to make return trips home than those born earlier. Thus cohorts show remarkable consistency in the proportion of life lived in the parental home. For the 1900-1929 birth cohorts, daughters’ lifetime probability that a parent will move in with them is approximately 15%; younger cohorts show similar age-specific probabilities to date. Explanations for these trends are considered.  相似文献

This paper analyzes cross-cohort trends in the age pattern of women at first birth in the United States. The analysis involves fitting the Coale-McNeil marriage model to the age distribution of first birth frequencies for a number of recent white and nonwhite cohorts. Methodologically, the results (a) provide support for the application of the Coale-McNeil marriage model to first birth data, and (b) demonstrate the ability of the model to accurately project first birth fertility for cohorts which have yet to complete their childbearing years. Substantively the results indicate (a) that the proportion of women who will never have a first birth is increasing across cohorts and can be expected to be as high as .25 and .20 for recent white and nonwhite cohorts respectively; (b) that recent nonwhite cohorts have an appreciable number of first births at earlier ages than their white counterparts, as well as a lower mean age at first birth and increasingly less dispersion (across cohorts) in their age at first birth; and (c) that the mean age at first birth and the proportion of first births occurring between ages 25 and 34 is increasing across cohorts of white women but is stable across cohorts of nonwhite women.  相似文献

This paper examines the concept of delayed childbearing in Australia, in comparison with other Western countries. In addition to presenting statistics to examine changes in the age at which women enter parenthood, survey data from the Australian Family Project are used to investigate the factors influencing the timing of the first birth. Using a framework proposed by Bloom (1984), the paper presents a proportional hazards regression model of first birth timing. Some attempt is made to examine changes over time in the factors affecting the age at first birth.  相似文献

Cohort lifetime distribution functions have been estimated for the twenty separate calendar year cohorts of South Australian males born in 1881–1900. A cohort life expectancy at birth was calculated from each of these distribution functions, and a composite assessment made of the reduction in cohort life expectancy at birth due to both World War I 1914–1918 and the 1918 Influenza Pandemic. By partitioning each cohort, the cohort life expectancy at birth of the subgroup that had overseas military service is estimated to be 85 to 90 per cent of the cohort life expectancy at birth of the subgroup that remained in South Australia.  相似文献

This paper examines the nature of the inverse association between age at first birth and fertility across successive generations of Ghanaian women. Within the context of enhanced non-marital opportunities for contemporary women and declining fertility, we develop a rationale for and test the hypothesis that in a medium fertility environment as currently found in Ghana, the effect of age at first birth on fertility becomes more important than ever before. Five birth cohorts were identified (1938–1944; 1945–1949;1950–1954; 1955–1959; 1960–1964)from a merged file of the 1988, 1993 and 1998 Ghana Demographic and Health Surveys. The analyses were restricted to women over 35 years old at the time of the surveys, which allowed us to use current parity as a reasonable proxy for completed fertility. Preliminary results suggest that women who had first births early tend to have a higher number of births than those whose first births occur late, regardless of birth cohort. In multivariate analyses, the effect of age at first birth as a determinant of fertility was found to be more substantial among later cohorts. The implications of the findings are discussed.  相似文献

The paper examines the change in the level and pattern of fertility that took place in the post-1971 period, and the downward completed fertility of successive generations of Australian women born since 1933–37. The change in cohort fertility is assessed in terms of the cohort parity progression ratios, and the four components of cohort total fertility: the proportion of women who proceeded to have a birth, mean age at first birth, mean age at last birth, and average interbirth interval for women who had at least two births. The other aspects discussed are the cohort fertility differentials and the implications of the current trends for future fertility in Australia.  相似文献

Objective

To identify the risk factors for preterm birth, low birthweight and small for gestational age babies among remote-dwelling Aboriginal women.

Methods

The study included 713 singleton births from two large remote Aboriginal communities in Northern Territory, Australia in 2004–2006 (retrospective cohort) and 2009–2011 (prospective cohort). Demographic, pregnancy characteristics, labour and birth outcomes were described. Multivariate logistic regression analysis was conducted and adjusted odds ratios were reported.

Results

The preterm birth rate was 19.4%, low birthweight rate was 17.4% and small for gestational age rate was 16.3%. Risk factors for preterm birth were teenage motherhood, previous preterm birth, smoker status not recorded, inadequate antenatal visits, having pregnancy-induced hypertension, antepartum haemorrhage or placental complications. After adjusting for gender and birth gestation, the only significant risk factor for low birthweight was first time mother. The only significant risk factor for small for gestational age baby was women having their first baby.

Conclusions

Rates of these events are high and have changed little over time. Some risk factors are modifiable and treatable but need early, high quality, culturally responsive women centred care delivered in the remote communities themselves. A different approach is recommended.  相似文献

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.  相似文献

ProblemTo date there is has been very little research into midwifery in Western Australia (WA), therefore this paper addresses a significant gap in the literature. The aim of this paper was to gain insight into the history of midwifery in WA.BackgroundSince the beginning of recorded history midwives have assisted women in childbirth. Midwifery is recognised as one of the oldest professions; midwives are mentioned in ancient Hindu texts, featured on Egyptian papyrus and in The Bible. Up until the seventeenth century childbirth was the responsibility of midwives, but the gradual emergence of barber-surgeons, then man-midwives and obstetricians heralded a shift from women-led and community-supported birth to a patriarchal and medical model. Throughout the twentieth century childbirth practices in the Western World have continued to change, leading to a move from midwifery-led care at home to doctor-led care in the hospital.DiscussionThe first non-Indigenous Australian midwives were not formally trained; they came on ships bringing convicts to Australia and are described as ‘accidental’ midwives, as assistance in childbirth came from whoever was available at the time. This period was followed by what was called the ‘Aunt Rubina’ period where older married women helped younger women in childbirth. Throughout the early 1800s untrained or ‘lay’ midwifery care continued alongside the more formally trained midwives who had arrived with the colonists.From the early 20th century, when birth moved into the hospital, midwives in WA have been incorporated into the hierarchy of the professions with obstetrics as the lead profession and midwifery considered a speciality of nursing. The role of the midwife has been subordinated, initially controlled by medicine and then incorporated into the institutions and nursing. The increase in legislative and training requirements for midwives throughout Australia and the move from home to the hospital, gradually led to the decrease in autonomous midwives working within the community, impacting women’s choice of birth attendant and place of birth.ConclusionThe historical suppression of midwifery in Australia has impacted the understanding of the role of the midwife in the contemporary setting. Understanding the development and evolution of the midwifery profession in Australia can help future directions of the profession.  相似文献

This paper presents estimates of delayed childbearing and permanent childlessness in the United States and the determinants of those phenomena. The estimates are derived by fitting the Coale-McNeil marriage model to survey data on age at first birth and by letting the parameters of the model depend on covariates. Substantively, the results provide evidence that the low first birth fertility rates experienced in the 1970s were due to both delayed childbearing and to increasing levels of permanent childlessness. The results also indicate that (a) delayed childbearing is less prevalent among black women than among nonblack women; (b) education is an important determinant of delayed childbearing whose influence on this phenomenon seems to be increasing across cohorts; (c) education is positively associated with heterogeneity among women in their age at first birth; (d) the dispersion of age at first birth is increasing across cohorts; (e) race has an insignificant effect on childlessness; and (f) education is positively associated with childlessness, with the effect of education increasing and reaching strikingly high levels for the most recent cohorts.  相似文献

With increases in nonmarital fertility, the sequencing of transitions in early adulthood has become even more complex. Once the primary transition out of the parental home, marriage was first replaced by nonfamily living and cohabitation; more recently, many young adults have become parents before entering a coresidential union. Studies of leaving home, however, have not examined the role of early parenthood. Using the Young Adult Study of the 1979 National Longitudinal Survey of Youth (n = 4,674), we use logistic regression to analyze parenthood both as a correlate of leaving home and as a route from the home. We find that even in mid-adolescence, becoming a parent is linked with leaving home. Coming from a more affluent family is linked with leaving home via routes that do not involve children rather than those that do, and having a warm relationship with either a mother or a father retards leaving home, particularly to nonfamily living, but is not related to parental routes out of the home.  相似文献

As parental ages at birth continue to rise, concerns about the effects of fertility postponement on offspring are increasing. Due to reproductive ageing, advanced parental ages have been associated with negative health outcomes for offspring, including decreased longevity. The literature, however, has neglected to examine the potential benefits of being born at a later date. Secular declines in mortality mean that later birth cohorts are living longer. We analyse mortality over ages 30–74 among 1.9 million Swedish men and women born 1938–60, and use a sibling comparison design that accounts for all time-invariant factors shared by the siblings. When incorporating cohort improvements in mortality, we find that those born to older mothers do not suffer any significant mortality disadvantage, and that those born to older fathers have lower mortality. These findings are likely to be explained by secular declines in mortality counterbalancing the negative effects of reproductive ageing.  相似文献

Data from the 1983 National Demographic Survey are used to analyze the proximate determinants of Philippine fertility in each of the 3 stages of family formation and to identify all of the direct and indirect factors affecting fertility levels and trends. 10,843 ever-married women and 12,771 children were included. The analysis pertains first to the starting patterns of family formation, the age at first birth, and the proximate determinants (age at menarche, age at first marriage/union, conception before first birth, fetal wastage first birth, interval between first marriage and first birth). Further analysis examines birth spacing patterns including the postpartum nonsusceptible period, the exposure interval and stopping patterns. Almost all births occur within marriage, and childbearing begins late at 22.5 years. However, 15.4% of first births are conceived premaritally. The mean age at first birth increases from younger to older cohorts. Urban women were slightly older (23.0 years) at the birth of their first child. Those with education below the 4th grade had first births 3.5 years earlier. Contraceptive use was low at 1.8% before first birth. Younger cohorts were more likely to use birth control and urban wives were more likely to use it than rural wives. 6.4% reported a first pregnancy ending in nonlive births, which were primarily spontaneous abortions (5.2%), stillbirths (1.0%), and induced abortions (.2%). 5.8% report never having been pregnant and 1.1% never having given birth to a live-born child. 20.4% were childless between the ages of 15-24 years, and 4.6% between 25-34 years. Childlessness was slightly higher among urban women (7.1%) than rural women (6.7%). A decreasing age at menarche has appeared; i.e., 13.6 years for the cohort 15-24 years, and 14.0 for the oldest cohort. By age 15, 82.9% had begun menstruating. The mean age at marriage is early at 20.7 years, and older cohorts tended to marry later at 21.4 years. Urban women marry a year later (21.4 years) than rural women. Lower educated women marry 4 years earlier. The mean length between first marriage and first birth was 18.4 months. In the younger cohorts, spacing patterns are shorter. Postpartum susceptibility is short. Return to sexual relations after a birth occurred at 2.8 months. The exposure time required to conceive is fairly long at 16.6 months and is attributed to contraceptive use, since coital frequency is high and temporary separation is infrequent. The average age at last birth is late at 37.6 years.  相似文献

BackgroundWomen born outside Australia make up more than a fifth of the Queensland birthing population and like migrants in other parts of the world face the challenges of cultural dislocation and possible language barriers. Recognising that labour and birth are major life events the aim was to investigate the experiences of these women in comparison to native-born English speaking women.MethodsSecondary analysis of data from a population based survey of women who had recently birthed in Queensland. Self-reported clinical outcomes and quality of interpersonal care of 481 women born outside Australia who spoke a language other than English at home were compared with those of 5569 Australian born women speaking only English.ResultsAfter adjustment for demographic factors and type of birthing facility, women born in another country were less likely to be induced, but more likely to have constant electronic fetal monitoring (EFM), to give birth lying on their back or side, and to have an episiotomy. Most women felt that they were treated as an individual and with kindness and respect. However, women born outside Australia were less likely to report being looked after ‘very well’ during labour and birth and to be more critical of some aspects of care.ConclusionIn comparing the labour and birth experiences of women born outside the country who spoke another language with native-born English speaking women, the present study presents a largely positive picture. However, there were some marked differences in both clinical and interpersonal aspects of care.  相似文献

The growing study of leaving home in young adulthood in the United States has been hampered by data and measurement problems, which are producing a major theoretical confusion about the role of parental resources in influencing young adults’ leaving home. Does high parental income retain young adults in the home or subsidize their leaving (and parental privacy)? This paper uses the 1984 panel of Survey of Income and Program Participation to clarify this issue, and shows that the effects of parental resources differ depending on the route out of the home under consideration (marriage or premarital residential independence). Effects change substantially over the nest-leaving ages, but relatively few differences are found between young men and young women.  相似文献
