Background: Obesity in late adolescence has been associated with an increased risk of multiple sclerosis (MS); however, it is not known if body size childhood MS risk. Methods: Using a prospective design we examined whether mass index (BMI) at ages 7–13 years was among 302,043 individuals the Copenhagen School Health Records Register (CSHRR). Linking CSHRR Danish registry yielded 774 cases (501 girls, 273 boys). We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95%...

A diagnosis of multiple sclerosis (MS) may impact the choice parenthood.To investigate number live births, abortions and ectopic pregnancies among persons with MS.From Danish Multiple Sclerosis Registry, we extracted data from all diagnosed MS 1960 to 1996 matched each person four reference persons. We used a negative binomial regression model for births Poisson pregnancies. The total fertility rate (TFR) during 1960-2016 annual in population were analysed.Persons had fewer children than...
