Early Life Factors and Their Role in Developing Multiple Sclerosis
Recent research highlights how childhood infections, stress, maternal age, and physical activity levels can influence the risk of developing multiple sclerosis later in life. Discover how early-life factors may impact MS development and prevention strategies.
Recent research conducted by scientists at the University Medical Center Hamburg-Eppendorf (UKE) and Heidelberg University Hospital (UKHD) has shed light on potential risk factors associated with the development of multiple sclerosis (MS) during childhood and adolescence. As part of the German National Cohort (NAKO), the study analyzed various environmental and lifestyle influences that might contribute to the onset of MS.
Published in Deutsches Ärzteblatt international, the study identified that frequent childhood infections, significant stressful life events, higher maternal age at first birth, and low levels of physical activity could be linked to an increased risk of developing MS later in life. The research confirmed several established risk factors such as family history, Epstein-Barr virus infection, and childhood obesity.
The investigation involved 576 individuals with confirmed MS diagnoses and 895 control subjects without MS, matched by birth year, sex, and study center. Using statistical methods to analyze the data, researchers found that each additional childhood infection was associated with a slightly higher risk of MS, as did stressful life events. Conversely, higher physical activity levels during adolescence appeared to have a protective effect.
Interestingly, the study uncovered that being the first-born child to a mother aged 30 or older doubled the risk of MS. However, no significant associations were observed with factors like passive smoking or outdoor activity in childhood.
Dr. Anja Holz, the study's first author, emphasized the importance of preventive measures: "Encouraging childhood vaccinations, promoting healthy lifestyles, and increasing physical activity during adolescence may help reduce MS risk." The findings of this research can pave the way for further investigations into how lifestyle modifications during early life stages might influence disease severity and prevention.
Overall, the study underscores the significance of early-life health and lifestyle factors in understanding and potentially reducing the risk of multiple sclerosis.
