Abstract

Insights

This meta-analysis reveals a high and increasing prevalence and incidence of multiple sclerosis (MS) in Iran. The study highlights the rising trend of MS epidemiology in the country over time.

Area of Science:

  • Neurology
  • Epidemiology

Background:

  • Multiple sclerosis (MS) is a common neurological disorder and a leading cause of disability.
  • Existing data on MS prevalence and incidence in Iran lacks systematic review and meta-analysis.
  • This study addresses the need for a comprehensive understanding of MS epidemiology in Iran.

Purpose of the Study:

  • To conduct a meta-analysis to determine the prevalence and incidence of multiple sclerosis (MS) in Iran.
  • To systematically review and synthesize existing epidemiological data on MS in Iran.
  • To identify trends in MS prevalence and incidence over time within the Iranian population.

Main Methods:

  • Systematic review and meta-analysis adhering to PRISMA guidelines.
  • Comprehensive search of eight international and six Persian databases until May 2018.
  • Data analysis using Comprehensive meta-analysis software (ver. 2) and registered in PROSPERO (ID: CRD42018114491).

Main Results:

  • The overall prevalence of MS in Iran was estimated at 29.3/100,000, with higher rates in women (44.8/100,000) than men (16.5/100,000).
  • The incidence of MS in Iran was estimated at 3.4/100,000, also showing a higher rate in women (44.8/100,000) compared to men (16.5/100,000).
  • Meta-regression indicated a significant increase in MS prevalence and incidence over the years (p<0.001).

Conclusions:

  • The meta-analysis provides a general overview of MS epidemiology in Iran.
  • Both the prevalence and incidence of MS in Iran are substantial and show an upward trend.
  • Findings underscore the growing public health concern of multiple sclerosis in Iran.

Review and Preview

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...

Introduction to Epidemiology

Epidemiology, known as the cornerstone of public health, involves studying the distribution and determinants of health-related events in defined populations and applying these insights to control health issues. This is essential for understanding how diseases spread, identifying populations at greater risk, and implementing measures to control or prevent outbreaks. Epidemiology addresses not only infectious diseases but also non-communicable conditions like cancer and cardiovascular disease,...

Causality in Epidemiology01:21

Causality in Epidemiology

Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

Study Designs in Epidemiology

Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

Confounding in Epidemiological Studies01:27

Confounding in Epidemiological Studies

Confounding in statistical epidemiology represents a pivotal challenge, referring to the distortion in the perceived relationship between an exposure and an outcome due to the presence of a third variable, known as a confounder. This variable is associated with both the exposure and the outcome but is not a direct link in their causal chain. Its presence can lead to erroneous interpretations of the exposure's effect, either exaggerating or underestimating the true association. This...
