Prevalence of multiple sclerosis in Saskatoon
Canadian Medical Association Journal
|August 15, 1982
Summary
Multiple sclerosis (MS) prevalence in Saskatoon was significantly higher than in other Canadian cities. This epidemiologic survey highlights elevated MS rates among residents and Saskatchewan-born individuals.
Area of Science:
- Epidemiology
- Neurology
Background:
- Multiple sclerosis (MS) is a chronic neurological disease with varying geographic prevalence.
- Understanding regional incidence and prevalence is crucial for public health initiatives.
Purpose of the Study:
- To determine the prevalence and incidence of probable and possible multiple sclerosis (MS) in Saskatoon.
- To compare these rates with those reported in other Canadian cities.
Main Methods:
- An epidemiologic survey was conducted using medical records from Saskatoon's three general hospitals.
- Data spanned from 1955 to 1980, with prevalence assessed on January 1, 1977.
Main Results:
- Probable MS prevalence was 111/100,000; combined probable and possible MS was 134/100,000.
- Average annual incidence over three decades was 4.8/100,000, 2-3 times higher than other Canadian cities.
- Prevalence was 64/100,000 among residents, 77/100,000 for Saskatchewan-born individuals, and 48/100,000 for immigrants.
Conclusions:
- Saskatoon exhibits notably higher multiple sclerosis prevalence and incidence rates compared to other Canadian urban centers.
- Geographic variations in MS risk factors may contribute to these observed differences.
