Summary
Antenatal depression (AD) affects pregnant women, with lifetime major depression and intimate partner abuse identified as key risk factors. Prevalence rates in Brazil are comparable to global figures.
Area of Science:
- Obstetrics and Gynecology
- Psychiatry
- Public Health
Background:
- Antenatal depression (AD) prevalence varies globally.
- Understanding AD risk factors is crucial for maternal health.
- This study focuses on a Brazilian pregnant population.
Purpose of the Study:
- To investigate antenatal depression prevalence in Brazilian pregnant women.
- To identify significant risk factors associated with AD.
- To analyze AD patterns across the second and third trimesters.
Main Methods:
- 148 pregnant women were assessed using semi-structured interviews and standardized depression scales (Edinburgh Postnatal Depression Scale, Beck Depression Inventory, MINI-Plus).
- Data were analyzed using bivariate and multivariate statistical methods.
- Prevalence and risk factors were examined in the second and third trimesters.
Main Results:
- Antenatal depression prevalence was 13.5% (second trimester) and 10.1% (third trimester) using the MINI-Plus.
- Lifetime major depression and intimate partner abuse were identified as independent risk factors for AD.
- No significant differences in AD prevalence or risk factors were observed between trimesters.
Conclusions:
- AD prevalence in this Brazilian sample aligns with worldwide rates.
- Lifetime major depression is the primary risk factor for antenatal depression.
- Limitations include potential selection bias and participant attrition.

01:18Depression: Overview
1.2K
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

4.3K
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,...

5.5K
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...

1.1K
Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

01:28Development of the Oral Microbiota
25
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
