Task 6
Stress Level Tied to Education Level
People with less education suffer fewer stressful days,according to a report in the current issue of the Journal of Health and SocialBehavior.
However, the study also found that when 1ess-educatedpeople did suffer stress it was more severe and had a larger impact on theirhealth.
From this。researchers have concluded that the day-to-day factors that cause stressare not random.Ⅵr11ere you are in society determines the kinds ofproblems that you have each day, and how well you will cope with them.
The research team interviewed a national sample of 1.031 adults daily for eight days about their stress level and health.Peoplewithout a high school diploma reported stress on 30 percent of the study days,people with a high school degree reported stress 38percent of the time,and people withcollege degrees reported stress 44 percent of the time.
Less advantaged people are less healthy on a dailybasis and are more likely to have downward turns in their health。’”lead researcher Dr.Joseph Grzywacz,of Wake Forest University Baptist Medical Center, saidin a prepared statement.“The downwardturns in health were connected with daily stressors.and the effect of dailystressors on their health is much more devastating for the less advantaged.”
Grzywacz suggested follow-up research to determine whyless-educated people report fewer days of stress when it is known their stress ismore acute and chronic.
“If something happens every day, maybe it’s not seen as a stressor”Grzywacz says.“Maybe it is just1ife.”
