Insights

This systematic review found the prevalence of autism spectrum disorder (ASD) in India to be 0.11% in rural areas and 0.09% in urban areas. More research is needed to understand the full burden of ASD in India.

Area of Science:

  • Epidemiology
  • Neurodevelopmental Disorders
  • Public Health

Background:

  • Autism spectrum disorder (ASD) is a significant developmental disability with broad public health and economic implications.
  • Estimating the population prevalence of ASD in India is crucial for resource allocation and service development.
  • There is a notable lack of evidence-based prevalence data for ASD in the Indian population.

Purpose of the Study:

  • To systematically review and determine the population prevalence of autism spectrum disorder (ASD) in India.
  • To synthesize existing data on ASD prevalence across different settings within India.

Main Methods:

  • A systematic review and meta-analysis of published studies on ASD prevalence in community settings.
  • Literature search conducted across major databases including PubMed, OvidSP, and EMBASE.
  • Data analysis performed using STATA MP12.

Main Results:

  • Four studies met the inclusion criteria for the systematic review.
  • The pooled prevalence of ASD in rural Indian children (aged 1-18) was 0.11% (95% CI 0.01-0.20).
  • The pooled prevalence of ASD in urban Indian children (aged 0-15) was 0.09% (95% CI 0.02-0.16).

Conclusions:

  • The current body of epidemiological research on ASD in India is limited.
  • There is an urgent need for high-quality, population-based studies to accurately assess the burden of ASD in India.
  • Improved data on ASD prevalence will facilitate the development of targeted rehabilitative services.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

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.

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...

The Electromagnetic Spectrum02:37

The Electromagnetic Spectrum

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...

The Electromagnetic Spectrum

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...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Review and Preview

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...
