Can you provide a little more info? What do you mean by 'stress causing elements' ? Is there a particular setting you're interested in? For example, work or health? Or are you looking more broadly - i.e., stress as a result of disadvantage?
this is very broad and I am wondering if you are talking about the psychosocial and behavioral determinants of health as stressors or are you talking about epigenetics?? At any rate, consider looking at the NHANES data for U.S. or think about the Health and Retirement Study for adults 50 and over. Both collect various health-related stressors. Hope this is helpful to you.
