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...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
Testing a Claim about Mean: Known Population SD01:11

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...
One-Way ANOVA: Unequal Sample Sizes01:15

One-Way ANOVA: Unequal Sample Sizes

One-way ANOVA can be performed on three or more samples of unequal sizes. However, calculations get complicated when sample sizes are not always the same. So, while performing ANOVA with unequal samples size, the following equation is used:
Pharmacokinetics in Pediatric Patients: Drug Distribution01:17

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...

Summary

Neonatal mortality rates were higher among Alaska Native infants compared to non-native infants. This disparity is linked to higher preventable birthweight-specific mortality, suggesting issues in perinatal care access and quality.

Area of Science:

  • Public Health
  • Neonatal Mortality Research
  • Health Disparities

Background:

  • Neonatal mortality rates and causes vary significantly across different demographic groups.
  • Understanding these disparities is crucial for improving infant health outcomes.

Purpose of the Study:

  • To compare neonatal mortality rates between Alaska Native and non-native populations in Alaska.
  • To analyze birthweight-specific and preventable birthweight-specific mortality in these populations.

Main Methods:

  • Utilized natality, mortality, and cause of death data from the State of Alaska's Bureau of Vital Statistics (BVS) for 1987-1996.
  • Analyzed mortality data stratified by birthweight: <1500 grams, 1500-2499 grams, and >=2500 grams.

Main Results:

  • Low birthweight (LBW) and very low birthweight (VLBW) rates were similar between populations.
  • Alaska Native infants exhibited higher neonatal mortality rates across all birthweight categories.
  • Excluding non-preventable conditions amplified mortality differences for infants under 2500 grams.

Conclusions:

  • Higher neonatal mortality in Alaska Native infants is associated with increased overall and preventable birthweight-specific mortality.
  • Disparities in mortality likely reflect differences in access to and quality of perinatal care.
