Hematological variables change significantly as a pregnancy progresses. Similarly, hematological variables also change significantly 24 h after birth. These changes are partly attributed to blood dilution, nutrition intake during the periods of pregnancy, and bleeding in the process of delivery [1,2]. A thorough understanding of the hematological changes can serve as a guide for disease diagnos...

It is widely acknowledged that age at marriage has a significant influence on fertility, particularly in countries where childbearing occurs within marriage. However, the complexities of this relationship are poorly understood, especially during fertility transitions. This paper investigates the complex relationship between marriage age and marital fertility by examining the initiation of child...

KEY FINDINGS Data from the National Vital Statistics System •Nearly 29.0% of U.S. mothers who had a second or higher-order birth in 2014 had a short interpregnancy interval of less than 18 months. •Short intervals (i.e., less than 6 months, 6-11 months, and 12-17 months) were more common for mothers aged 35 and over (5.7%, 16.3%, and 22.1%, respectively) than mothers who were under age 20 at th...

background: in recent years, the study of birth intervals has been a main determinant of the levels of fertility in the populations, as it is associated with rates of fertility and population growth. objective: the purpose of this study was to firstly apply survival analysis for modeling of first birth interval and secondly to explore its determinants. materials and methods: in a cross sectiona...

The authors conducted a case-control study to determine whether risk factors for reading disability (RD) differentially affect boys and girls. The study population included all children born between 1976 and 1982 in Olmsted County, Minnesota (n = 5,701). A total of 303 RD cases were identified by using intelligence quotient and achievement test scores collected from school and medical records. ...

OBJECTIVES To examine the consequences of cervical conisation in terms of adverse outcome in subsequent pregnancies. DESIGN Population based cohort study. DATA SOURCES Data on cervical conisation derived from the Cancer Registry of Norway and on pregnancy outcome from the Medical Birth Registry of Norway, 1967-2003. 15 108 births occurred in women who had previously undergone cervical conis...

PURPOSE The object of this study was to determine factors leading to episiotomy in low-risk vaginal deliveries, including a comparison of family physicians with obstetricians. The research was also to assess the incidence of episiotomy in a large community hospital and compare it with a national rate of 40%. METHODS A retrospective cohort design was used with computerized records from one hos...

OBJECTIVE Mothers of multiple births face higher rates of postpartum depression, yet evidence on the marital consequences of multiple births is limited. We examined the association between twin births and parental divorce. METHODS We used the 1980 U.S. Census to identify a large sample of mothers with and without twin births. The goal was to estimate multivariate logistic models of the associ...

The authors investigated the recurrence risk of congenital anomalies as a function of changes in genetic and environmental factors in single births following the birth of a child with an anomaly. The study is a population-based historical follow-up using the Danish Medical Birth registry, hospital discharge diagnoses, and Statistic Denmark's Fertility Database. The investigators identified 8,67...
