Insights

Adolescent pregnancy in Bangladesh does not significantly increase infant mortality risk when healthcare access is considered. Improving maternal healthcare is key to reducing infant deaths.

Area of Science:

  • Public Health
  • Demography
  • Maternal and Child Health

Background:

  • Bangladesh faces a high infant mortality rate (38 deaths/1,000 live births).
  • Adolescent pregnancy is a global risk factor for maternal and infant health.
  • The specific impact of adolescent pregnancy on infant mortality in Bangladesh is under-researched.

Purpose of the Study:

  • To investigate the association between adolescent pregnancy and infant mortality in Bangladesh.
  • To analyze how sociodemographic, contextual, and healthcare utilization factors modify this relationship.

Main Methods:

  • Cross-sectional analysis of the Bangladesh Demographic and Health Survey 2017-18 data.
  • Included 8,759 infants born to mothers aged 15-49 years.
  • Used logistic regression to assess the association between adolescent pregnancy and infant mortality, controlling for covariates.

Main Results:

  • Infants born to mothers younger than 16 initially had higher mortality odds (AOR: 1.45).
  • This association remained significant after adjusting for sociodemographic and contextual factors (AOR: 1.41).
  • The association was no longer statistically significant after accounting for healthcare utilization (AOR: 1.06).

Conclusions:

  • Delaying childbirth from adolescence to adulthood may reduce infant mortality.
  • Adolescent pregnancy alone does not elevate infant mortality risk when healthcare utilization is considered.
  • Improving access to quality antenatal and postnatal care is crucial for reducing infant mortality in Bangladesh.

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...

Oogenesis02:07

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Meiosis vs. Mitosis02:57

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...

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...

Actuarial Approach

The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
Consider the example of a high-risk surgical procedure with significant early-stage mortality. A two-year clinical study is conducted,...

Attachment

Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that...
