摘要
In a Swedish population-based case-control study (1571 cases, 3371 controls), subjects with different body mass indices (BMIs) were compared regarding multiple sclerosis (MS) risk, by calculating odds ratios (OR) with 95% confidence intervals (95% CI). Subjects whose BMI exceeded 27 kg/m(2) at age 20 had a two-fold increased risk of developing MS compared with normal weight subjects. Speculatively, the obesity epidemic may explain part of the increasing MS incidence as recorded in some countries. Measures taken against adolescent obesity may thus be a preventive strategy against MS.
