Background/objectives: Alcohol use during pregnancy can result in adverse outcomes for the offspring, including Fetal Alcohol Spectrum Disorders (FASD). Psychosocial and contextual factors may influence gestational alcohol intake and women's risk perception. This systematic review aimed to assess pregnant women's and women of childbearing age's perceived risk of alcohol use during pregnancy and to evaluate their knowledge of its potential effects on children. Methods: Following the PRISMA guidelines, a systematic search was conducted in Web of Science, PubMed and PsycArticles databases for studies published up to May 2025. Eligible studies examined gestational alcohol use, risk perception, or knowledge of fetal consequences among pregnant women or women of reproductive age. Methodological quality was assessed with the Critical Appraisal of Qualitative Studies tool from the Centre for Evidence-Based Medicine (CEBM). Results: Twenty-nine studies were included. Reported prevalence of alcohol consumption during pregnancy varied considerably across settings. A substantial proportion of women perceived alcohol use during pregnancy as acceptable, often depending on quantity, frequency, type of beverage, or stage of gestation. Knowledge of FASDs was generally limited and frequently restricted to physical malformations. Misconceptions were more common among women with prior alcohol use. The findings highlight persistent gaps in risk perception and knowledge about FASDs. Conclusions: Prevention strategies should not be limited to pregnant women but should also target women of childbearing age, especially those with active drinking patterns, as well as their immediate sociocultural environment. Strengthening professional training, community-based interventions, and consistent public health messaging are essential to reduce gestational alcohol exposure.

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...

CNS Depressants: Alcohol and Nicotine

Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Hypothesis Test for Test of Independence01:16

Hypothesis Test for Test of Independence

The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics01:23

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by...

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

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,...

Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
