Summary
Hypertensive disorders in pregnancy increased globally, especially in low-income regions, despite declining age-standardized rates. Future trends predict decreasing incidence, aiding targeted health policy for maternal health.
Area of Science:
- Epidemiology
- Public Health
- Maternal Health
Background:
- Maternal hypertensive disorders represent a significant global health challenge, disproportionately affecting low sociodemographic index (SDI) regions.
- Understanding epidemiological trends is crucial for effective intervention and management.
Purpose of the Study:
- To reveal and predict epidemiological trends of hypertensive disorders during pregnancy worldwide.
- To analyze variations based on sociodemographic index (SDI) and age groups.
Main Methods:
- Utilized Global Burden of Disease 2019 data.
- Employed an age-period-cohort model to assess trends and effects.
- Applied autoregressive integrated moving average (ARIMA) models for future projections and risk factor analysis.
Main Results:
- Worldwide hypertensive disorders in pregnancy increased by 10.9% from 1990-2019, primarily in low-SDI countries.
- Age-standardized incidence declined globally (-23.6%), with a net drift of -0.8%, though some high-SDI nations showed positive drift.
- Incidence peaked in the 20-29 age group; unfavorable period effects emerged post-2010 in high/middle-high SDI countries. Projections indicate a downward trend by 2030.
Conclusions:
- Significant regional, national, and age-related variations in hypertensive disorders during pregnancy burden exist, stratified by SDI.
- Findings support targeted, cost-effective health policy, resource allocation, and improved maternal health management.

01:33Hormonal Regulation
32.8K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

01:07Teratogenicity
2.3K
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...

2.1K
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...

1.9K
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

63.3K
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...

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
