ABSTRACT
BACKGROUND: Multiple sclerosis (MS) is accompanied by many health-related issues. This study aimed to evaluate the anthropometric indices, nutrient intakes and health-related characteristics of MS patients as well as their possible correlations. METHODS: This cross-sectional study was performed on 283 MS patients in Shiraz, Iran, during 2018-2019. Body mass index (BMI) and body composition were measured for each participant. A food frequency questionnaire was used to determine the patients' nutrient intakes. The level of fatigue, disability and quality of life of the individuals were assessed by the modified fatigue impact scale (MFIS), the expanded disability status scale and the multiple sclerosis quality of life-54 questionnaires, respectively. RESULTS: The results revealed that 43.11% of the patients were overweight or obese, and their %body fat (%BF) was 35.65 ± 7.63. Besides, intakes of vitamins A, E, D, folic acid, calcium, zinc and magnesium were significantly lower than recommendations in both genders, and sodium intake was significantly higher than the tolerable upper intake level in females. A significant positive linear correlation was observed between MFIS and BMI (r = 0.12, P = 0.045). Significant positive correlations were also found between psychosocial subscale of MFIS and both of %BF (r = 0.12, P = 0.049) and visceral fat area (r = 0.14, P = 0.02). Unexpectedly, the patients' quality of life showed significant negative correlations with fat free mass and skeletal muscle mass. CONCLUSION: Being overweight, having a high %BF and poor nutrient intakes are common among MS patients. Improving the patients' lifestyle and dietary intake is recommended to reduce fatigue and increase their life quality.
ABSTRACT
BACKGROUND: The role of dietary interventions in improving the symptoms of Multiple Sclerosis (MS) has always been considered, but few studies have been conducted in this area. This study aimed to investigate the effects of modified anti-inflammatory diet on fatigue, quality of life, and inflammatory markers among patients with Relapsing-Remitting Multiple Sclerosis (RRMS). METHODS: This randomized clinical trial was conducted on 100 patients with RRMS. The patients were randomly divided into the diet group (anti-inflammatory diet) or the control group (healthy diet recommendations) for 12 weeks. Fatigue and quality of life were assessed by Modified Fatigue Impact Scale (MFIS) and Multiple Sclerosis Quality of Life (MSQoL-54), respectively. Anthropometric measures and inflammatory biomarkers, including Interleukin 17 (IL-17), Interleukin 4 (IL-4), and high sensitivity C-Reactive Protein (hs-CRP), were assessed at baseline and end of the study. RESULTS: The results showed a significant improvement in MFIS as well as in physical and mental components of MSQoL-54 (p = 0.001, p = 0.015, and p = 0.003, respectively) in the diet group compared to the control group. The results also showed a significant increase in IL-4 level (p = 0.022). However, no significant changes were detected in IL-17 and hs-CRP levels (p = 0.091, 0.418, respectively). CONCLUSION: Modified anti-inflammatory diet could improve fatigue and quality of life and increase IL-4 level.
