Background:
Obesity is common in the United States and is associated with a higher risk of relapse and comorbidities, and increased disease progression, in people with MS.
Methods:
We examined the prevalence of overweight and obesity in the MS Sunshine Study, a matched case-control study of multiple sclerosis in Southern California (470 cases, 519 controls). We reported the proportion of participants who adopted a specific diet for nutrition or weight loss purposes, and identified independent predictors of dieting.
Results:
In the total population, 32% and 37% were overweight and obese, respectively. Case participants were no more likely to adopt a specific diet for nutrition or weight loss purposes than control participants (10% and 11%, respectively). Being obese, younger, female or non-Hispanic were independently associated with dieting.
Conclusion:
Despite the evidence that obesity can worsen MS prognosis, and the high prevalence of overweight/obesity, case participants were no more likely to adopt a specific diet than control participants. Improved nutrition education may help people with MS make healthy dietary changes for nutrition or weight loss purposes.
Insights
Despite high obesity rates in multiple sclerosis (MS) patients, those with MS were no more likely to diet than controls. Improved nutrition education is recommended for MS patients to encourage healthy dietary changes.
Area of Science:
- Neurology
- Public Health
- Nutrition Science
Background:
- Obesity is prevalent in the United States, posing risks for multiple sclerosis (MS) patients.
- Obesity is linked to increased MS relapse rates, comorbidities, and disease progression.
Purpose of the Study:
- To determine the prevalence of overweight and obesity in individuals with MS.
- To compare dieting behaviors between MS patients and controls.
- To identify predictors of dieting in this population.
Main Methods:
- A matched case-control study, the MS Sunshine Study, analyzed 470 MS cases and 519 controls in Southern California.
- Prevalence of overweight and obesity was assessed.
- Diet adoption for nutrition or weight loss and its predictors were reported.
Main Results:
- Overall, 32% of participants were overweight and 37% were obese.
- MS cases and controls showed similar rates of adopting specific diets (10% vs. 11%).
- Obesity, younger age, female sex, and non-Hispanic ethnicity were associated with dieting.
Conclusions:
- High rates of overweight/obesity exist in MS patients, yet they do not diet more frequently than controls.
- Obesity negatively impacts MS prognosis, highlighting a gap in dietary intervention.
- Enhanced nutrition education may facilitate healthier dietary choices for individuals with MS.
