Population Growth00:57

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
Applications of Life Tables01:22

Applications of Life Tables

Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Study Designs in Epidemiology01:20

Study Designs in Epidemiology

Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.

Summary
This summary is machine-generated.

Planned births, including inductions and cesarean deliveries before term, are rising. This trend has not reduced stillbirth rates but has coincided with increased maternal and neonatal morbidity.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Neonatal Health

Background:

  • Planned births, encompassing prelabor cesarean sections and labor inductions, have become more common.
  • Understanding the trends and associated outcomes of these interventions is crucial for optimizing perinatal care.

Purpose of the Study:

  • To describe the trends in planned births (prelabor cesarean section and labor inductions) from 2001-2009.
  • To analyze the association between increasing planned births and maternal/neonatal outcomes, including stillbirth rates.

Main Methods:

  • Analysis of linked birth and hospital records for 779,521 singleton births at ≥33 weeks' gestation (2001-2009).
  • Examination of trends in prelabor cesarean deliveries and labor inductions before 40 weeks' gestation.
  • Assessment of composite indicators for maternal and neonatal morbidity/mortality.

Main Results:

  • A significant increase in labor inductions and prelabor cesarean deliveries before 40 weeks' gestation was observed between 2001-2009.
  • Despite the rise in planned births, there was no significant decrease in the stillbirth rate.
  • An increase in neonatal and maternal morbidity rates was noted, coinciding with earlier birth timing.

Conclusions:

  • The increasing rate of planned births before the due date is not associated with a reduction in stillbirths.
  • The shift towards earlier planned births may be linked to increased maternal and neonatal morbidity.
