Prevalence and Incidence

927
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Regression Toward the Mean

6.5K
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...

Summary
This summary is machine-generated.

The COVID-19 lockdown in Israel saw a 9.7% decrease in singleton preterm births. This reduction may be linked to environmental and lifestyle changes during the lockdown period.

Area of Science:

  • Reproductive Health
  • Epidemiology
  • Public Health

Background:

  • The coronavirus disease 2019 (COVID-19) pandemic led to unprecedented public health interventions, including national lockdowns.
  • Understanding the impact of these lockdowns on maternal and infant health outcomes is crucial for public health policy.
  • Preterm birth is a significant concern, and its potential association with lockdown measures warrants investigation.

Purpose of the Study:

  • To evaluate the effect of the COVID-19 pandemic's national lockdown period on the rate of singleton preterm births in Israel.
  • To compare preterm birth rates during the lockdown with pre-lockdown and post-lockdown periods, as well as corresponding periods in previous years.

Main Methods:

  • A population-based cohort study was conducted, analyzing data from 341,291 singleton infants born between January and July 2017-2020 in Israel.
  • Multivariable logistic regression analyses were employed to assess the influence of the lockdown period (March 11–May 5, 2020) on preterm birth rates.
  • Comparisons were made to pre-lockdown (Jan 1–Mar 10, 2020), post-lockdown (May 6–Jun 30, 2020), and corresponding periods in 2017-2019.

Main Results:

  • The preterm birth rate significantly decreased by 9.7% during the national lockdown period, falling from 5.05% in the pre-lockdown period to 4.56%.
  • This represented an adjusted decrease of -0.52% (95% CI: -0.89% to -0.15%), with an odds ratio of 0.898 (95% CI: 0.832 to 0.970).

Conclusions:

  • The national lockdown implemented in Israel during the COVID-19 pandemic was associated with a significant decline in singleton preterm births.
  • Potential contributing factors to this decrease include environmental changes and alterations in lifestyle and societal behavior during the lockdown.
  • Further research is needed to elucidate the specific mechanisms driving this observed reduction in preterm deliveries.
