Multiple sclerosis (MS) is the most common non-traumatic condition that leads to disability among young individuals. It is associated with demyelination, inflammation, and neurodegeneration within the central nervous system. Information on risk factors of multiple sclerosis is crucial for the prevention and control of the disease. The aim of this study was to determine risk factors of MS among adults in Saudi Arabia. A matched multicenter case-control study, including 307 MS patients and 307 healthy controls, was conducted in MS clinics and wards in 3 main cities of Saudi Arabia. Age, gender, and hospital were matched. Information on demographics, family history of MS, past medical and family history, sun exposure at different age periods, tobacco use, diet, consanguinity, and coffee consumption was obtained from self-administered questionnaires. ORs and 95% confidence intervals (CIs) were calculated. A conditional logistic regression model was used to control for potential confounding factors. The conditional logistic regression adjusted for age and gender showed that being the first child in the family (Adjusted Odds Ratio (AOR) 1.68, 95% CI: 1.03-2.74), having a family history of MS (AOR 5.83, 95% CI: 2.83-12), eating fast food ≥5 times weekly (AOR 2.05, 95% CI: 1.03-4.08), and having had measles (AOR 3.77, 95% CI: 2.05-6.96), were independently associated with an increased risk of MS. In contrast, eating ≥5 servings of fruit per week (AOR 0.25, 95% CI: 0.16-0.38), drinking coffee daily (AOR 0.46, 95% CI: 0.31-0.68), and having a high level of sun exposure at the primary school level and university level (AOR 0.57, 95% CI: 0.38-0.85 and AOR 0.48, 95% CI: 0.30-0.76, respectively) were independently associated with a decreased risk of MS. Our study suggested that high levels of sun exposure during primary school and university, consumption of fruits and drinking coffee protect against MS. In contrast, eating fast food was associated with an increased risk of the disease. Encouraging outdoor activity and healthy diets in school, especially for females, is highly recommended.

Attention Score in Context

This research output has an Altmetric Attention Score of 10. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 July 2019.
All research outputs
of 16,722,463 outputs
Outputs from BMC Neurology
of 1,861 outputs
Outputs of similar age
of 280,999 outputs
Outputs of similar age from BMC Neurology
of 1 outputs
Altmetric has tracked 16,722,463 research outputs across all sources so far. Compared to these this one has done well and is in the 86th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,861 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.0. This one has done well, scoring higher than 84% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 280,999 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 79% of its contemporaries.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
