Insights

Inadequate birth weight in newborns during the COVID-19 pandemic was linked to premature birth and cesarean delivery. Maternal factors like lack of exercise and lower gestational weight gain also played a role.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Health
  • Epidemiology

Background:

  • The COVID-19 pandemic introduced unprecedented challenges to maternal and neonatal healthcare.
  • Understanding the impact of pandemic-related factors on birth weight is crucial for public health strategies.

Purpose of the Study:

  • To evaluate the birth weight of newborns born to mothers during the COVID-19 pandemic.
  • To identify factors associated with inadequate birth weight in this population.

Main Methods:

  • A cross-sectional study involving 470 mother-newborn pairs from Brazilian public hospitals in 2020.
  • Data collected via medical records and postnatal interviews.
  • Multinomial logistic regression analysis to determine associations with birth weight.

Main Results:

  • Prevalence of low and insufficient birth weight was 9.8% and 25.7%, respectively.
  • Low birth weight was significantly associated with prematurity and cesarean delivery.
  • Insufficient birth weight was linked to prematurity, maternal physical inactivity, and lower gestational weight gain.

Conclusions:

  • Inadequate birth weight during the pandemic is multifactorial, influenced by prematurity, delivery mode, and maternal lifestyle factors.
  • Emphasizes the need for robust prenatal care and promotion of healthy maternal lifestyles, even during public health crises.

Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

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...

Obesity01:24

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

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...

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.

Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
