This can result in increased risk of depression, post-traumatic stress disorder, and anxiety disorders in adulthood.
A study of Danish soldiers found that childhood experiences of family violence and emotional problems predicted the onset of PTSD. The researchers suggest that social support and camaraderie during army life minimized mental health benefits for these soldiers, leading to increased symptoms after deployment.
Only three percent of patients receive stress management counselling, highlighting the need for restructuring primary care delivery to include this crucial service as prevention. Stress management counseling is associated with longer office visits, underscoring the importance of providing this support earlier in the disease process.
