New research from Carnegie Mellon University's Rodlescia
Sneed and Sheldon Cohen shows that unpleasant or demanding interpersonal
encounters increase hypertension risk among older adults.
Published in the American Psychological Association's
journal Health Psychology, the study provides some of the first concrete
evidence that negative social interactions not only influence psychological
well-being but also physical health – in this case, blood pressure levels.
Hypertension affects an estimated 65 million Americans and is a major
contributor to cardiovascular disease, the leading cause of death in the U.S.
"This demonstrates how important social networks are as
we age - constructing strong, positive relationships are beneficial to
prolonged health," said Cohen, the Robert E. Doherty University Professor
of Psychology in the Dietrich College of Humanities and Social Sciences.
For the study, Sneed and Cohen used data from the Health and
Retirement Study, a multi-year survey of 1,502 healthy adults aged 50 and over.
In 2006, the frequency of negative interactions – exchanges or behaviors that
involved excessive demands, criticism, disappointment or other unpleasantness –
with their partners, children, other family members and friends was assessed by
questionnaire. Blood pressure was measured at this assessment as well as four
years later.
The results show that each increase in the total average
negative social interaction score was associated with a 38 percent increased
chance of developing hypertension over the four-year period. Younger older
adults – those aged 51-64 – were also more affected than those 65 or older.
The researchers also observed sex differences in their
findings. While negative interactions predicted hypertension risk among women,
these interactions were not related to hypertension risk among men.
"There is a body of evidence in social psychology
research suggesting that women care more about and pay more attention to the
quality of their relationships," said Sneed, a Ph.D. candidate in
psychology. "Our findings suggest that women are particularly sensitive to
negative interactions, which is consistent with this previous work."
The researchers also found that the type of relationship
matters. Negative interactions between friends and family led to an increase in
hypertension risk while poor encounters with partners and children did not make
a difference.
"Interpersonal conflicts are the most commonly reported
stressor, so understanding their impact on health and well-being is
particularly important," said Sneed.
