Childhood stressors in the development of fatigue syndromes: a review of the past 20 years of research.
Borsini, A, Hepgul, N, Mondelli, V et al.·Psychological medicine·2014
This review looked at 31 studies to see if stressful experiences during childhood might increase the chance of developing ME/CFS or fibromyalgia later in life. The researchers found that people who experienced childhood stress were 2-3 times more likely to develop these fatigue conditions compared to those without such experiences. They also found that people with these conditions who had experienced childhood stress were more likely to also develop depression, anxiety, and pain.
