Age at onset of multiple sclerosis is correlated to use of combined oral contraceptives and childbirth before diagnosis

The aim of this study was to evaluate whether age of onset of multiple sclerosis is related to use of combined oral contraceptives and/or timing of childbirth. The results showed that use of combined oral contraceptives and childbirth before the first multiple sclerosis symptom was correlated to a higher mean age at the onset of the disease.
