AUTISM SPECTRUM DISORDER AND POSTNATAL FACTORS: A CASE-CONTROL STUDY IN BRAZIL
Fernanda Alves Maia1, Liliane Marta Mendes Oliveira1, Maria Tereza Carvalho Almeida1

Summary
Congenital malformations, neonatal jaundice, and childhood seizures are linked to Autism Spectrum Disorder (ASD). Multiple postnatal complications significantly increase ASD risk in Brazilian children.
Area of Science:
- Neurodevelopmental Disorders
- Pediatric Health
- Epidemiology
Background:
- Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition.
- Understanding the role of postnatal factors in ASD etiology is crucial for early intervention.
- Previous research has explored various risk factors, but population-specific data are needed.
Purpose of the Study:
- To investigate the association between Autism Spectrum Disorder (ASD) and specific postnatal factors.
- To quantify the magnitude of these associations in a Brazilian population.
- To identify potential etiological contributors to ASD.
Main Methods:
- A case-control study design was employed.
- Data were collected from 253 individuals with ASD and 886 controls.
- Semi-structured questionnaires and multiple logistic regression analysis were used to determine Odds Ratios (OR).
Main Results:
- Congenital malformations showed a strong association with ASD (OR 4.24).
- Neonatal jaundice (OR 1.43) and absence of crying at birth with childhood seizures (OR 5.75) were also associated.
- Individuals with two or more postnatal complications had a significantly higher risk (OR 6.39).
Conclusions:
- Postnatal factors including malformations, neonatal jaundice, and childhood seizures are significant considerations in ASD etiology.
- These findings highlight the importance of monitoring and addressing specific postnatal complications.
- Further research into these associations can inform preventative strategies and clinical management of ASD.

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

02:37The Electromagnetic Spectrum
64.8K
The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...

Electromagnetic waves are categorized according to their wavelengths and frequencies, giving the electromagnetic spectrum. These waves are classified as radio, infrared, ultraviolet, etc. Radio waves refer to electromagnetic radiation with wavelengths ranging from millimeters to kilometers. Radio waves are commonly used for audio communications (i.e., radios) and typically result from an alternating current in the wires of a broadcast antenna. They cover a broad wavelength range and are used...

01:19IR Spectrum
2.0K
When infrared (IR) radiation passes through a molecule, the bonds stretch or bend by absorbing the radiation. This absorption creates the molecule's absorption spectrum, which is the plot of its percentage transmittance versus wavenumber.
Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0%...

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

4.0K
A mass spectrum is the graphical representation of the relative abundance of the charged fragments in an analyte plotted against their mass-to-charge ratio (m/z). The plot's x-axis represents the ratio of the mass of the charged fragment to the number of charges it carries. The y axis of the plot represents the relative abundance of each charged species. The relative abundance is calculated from the signal intensity of each charged species recorded at the detector. The most intense signal (the...
