Insights

Major malformations at birth were similar among Jewish and Christian infants but higher in Muslim and Druze infants in Israel. This may be linked to consanguinity and abortion rates in these communities.

Area of Science:

  • Public Health
  • Genetics
  • Epidemiology

Background:

  • Understanding the prevalence of major malformations is crucial for public health initiatives.
  • Religious communities may exhibit distinct patterns of congenital anomalies due to cultural and socioeconomic factors.

Purpose of the Study:

  • To determine the birth prevalence of major malformations across different religious communities in Israel.
  • To investigate potential contributing factors, such as consanguinity and abortion rates, to observed prevalence differences.

Main Methods:

  • Analysis of a national registry of birth defects data spanning a 10-year period.
  • Inclusion of over 1.2 million liveborn infants, categorized by religious affiliation.
  • Comparison of malformation rates between Jewish, Christian, Muslim, and Druze communities.

Main Results:

  • Major malformation prevalence was comparable between Jewish and Christian infants.
  • Significantly higher prevalence of major malformations was observed in Muslim and Druze infants.
  • Higher rates of consanguinity and lower rates of therapeutic abortion were noted in Muslim and Druze communities.

Conclusions:

  • Religious affiliation is associated with varying rates of major malformations at birth in Israel.
  • Consanguinity and decisions regarding therapeutic abortion appear to be significant factors influencing these disparities.
  • This research provides valuable insights for public health planning and future etiological studies on birth defects.

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...

Meiosis vs. Mitosis

Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...
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...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Testing a Claim about Mean: Known Population SD

A complete procedure of testing the hypothesis about a population mean is explained here.
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
