Background: Multiple sclerosis (MS) is a complex inflammatory disease of the central nervous system. Despite extensive research, its exact cause is unknown. One of the roles of nurses is discovery and prevention of factors related to the disease. This study aimed to investigate several food items concerning the etiology of MS in a population of Ahvaz (Iran).

Materials and Methods: This case-control study was conducted on 113 MS patients and 113 healthy women. Food information was collected through interviews using a standard designed questionnaire. Statistical analysis was performed by adopting descriptive tests (mean, frequency, standard deviation) and inferential tests (Chi-square test, Fisher’s exact test, logistic regression, and multivariate conditional logistic regression with a significance level of 0.05 and 95% confidence interval) through SPSS version 19.

Results: Univariate regression analysis showed a significant association between MS and consumption of solid vegetable oil (P = 0.004), fruits (P = 0.002), vegetables (P = 0.016), dates (P = 0.02), and low-fat dairy (P = 0.009) more than five times a week. According to multivariate conditional logistic regression analysis, consumption of fruits (P = 0.03) and low-fat dairy (P = 0.04) more than five times a week had a protective role and solid vegetable oil consumption was significantly associated with a risk for MS (P = 0.01).

Conclusions: This study suggests a protective role of consumption of fruits and low-fat dairy in MS and an increased risk of MS with solid vegetable oil consumption in Ahvaz (Iran).
