Insights

Preterm birth affects 5.1% of newborns in Ardabil, Iran. Key risk factors include previous preterm birth, hypertension, and preeclampsia, highlighting the need for early detection and improved maternal healthcare to reduce incidence.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Health
  • Public Health

Background:

  • Preterm birth is a primary cause of neonatal mortality and long-term health issues.
  • Understanding regional prevalence and risk factors is crucial for targeted interventions.

Purpose of the Study:

  • To determine the prevalence of preterm birth in Ardabil, Iran.
  • To identify significant risk factors associated with preterm birth in the region.

Main Methods:

  • A case-control study was conducted from November 2010 to July 2011.
  • Data were collected from 6705 live births, with 346 preterm and 589 term neonates analyzed.
  • Univariate and multivariate logistic regression models were employed to assess risk factors.

Main Results:

  • The prevalence of preterm birth was found to be 5.1%.
  • Significant risk factors included prior preterm birth (OR=12.7), hypertension (OR=7.3), oligohydramnios (OR=3.9), spouse abuse (OR=3.7), preeclampsia (OR=3.6), and premature rupture of membranes (OR=3.1).
  • Other identified risks were bleeding during pregnancy, hyperemesis gravidarum, urinary tract infections, and low diastolic blood pressure.

Conclusions:

  • Early detection and management of maternal conditions like hypertension, oligohydramnios, preeclampsia, and infections are vital.
  • Improving the quality of maternal healthcare services can potentially lower the rate of preterm birth.

Prevalence and Incidence01:08

Prevalence and Incidence

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...

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Factors Affecting Illness01:18

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

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...

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...
