This can result in increased risk of depression, post-traumatic stress disorder, and anxiety disorders in adulthood.
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.

Women also showed stronger emotional responses to the negative news they had viewed previously, suggesting a gender difference in how we react to negative news in the media.
Researchers found that chronic stress predicts greater increases in body weight over time in both black and white girls. However, the negative effect of chronic stress on black girls' weight may explain racial disparities in obesity levels. The study suggests stress may play a role in the obesity epidemic and racial disparities.
